2Overview
2.1 Introduction
Some intelligent UEs on a live network send a Signaling Connection Release Indication (SCRI)
message to the RNC after PS data transmission is complete. By sending the SCRI message,
intelligent UEs request for a transition to idle mode or the CELL_PCH/URA_PCH state to reduce
battery consumption. Upon receiving the SCRI, the RNC can release the signaling connection
and switch the UEs to idle mode, or the RNC can maintain the signaling connection and switch
the UEs to the CELL_FACH or CELL_PCH/URA_PCH state.
By default, the RNC switches the UEs to idle mode. A UE setting up PS services in idle mode
consumes more signaling resources than that in the CELL_FACH or CELL_PCH/URA_PCH
state. If a large number of UEs are switched between idle mode and the CELL_DCH state,
signaling storms may occur. The EFD feature is introduced to switch the UEs to the
CELL_FACH or CELL_PCH/URA_PCH state to relieve signaling storms.
The UEs on a live network are classified into the following types:
l UEs that do not send an SCRI message (earlier than 3GPP Release 5)
This type of UE is of a release earlier than 3GPP Release 5 and does not send an SCRI
message after completing data transmission.
l UEs that do not send an SCRI message (3GPP Release 5 and later)
This type of UE is of 3GPP Release 5 or later and does not send an SCRI message after
completing data transmission.
l UEs that send an SCRI message (with the "UE Requested PS Data session end" cause value)
This type of UE reads the T323 information element (IE) carried in the system information
block type 1 (SIB1) message and sends an SCRI message to the RNC after completing data
transmission. The SCRI message carries the "Signaling Connection Release Indication
Cause" IE, which is set to "UE Requested PS Data session end." This type of UE complies
with 3GPP Release 8.
T323 determines the interval at which a UE sends an SCRI message. That is, the T323 timer
starts after a UE sends an SCRI message, and SCRI messages with the "UE Requested PS
Data session end" cause value cannot be sent until T323 expires.
l UEs that send an SCRI message (with other cause values or no cause value)
WCDMA RAN
Enhanced Fast Dormancy Feature Parameter Description 2 Overview
5

This type of UE does not read the "T323" IE carried in the SIB1 message, and sends an
SCRI message to the RNC after completing data transmission.
– The message carries the "Signaling Connection Release Indication Cause" IE and the
IE is set to cause values other than "UE Requested PS Data session end."
– The message does not carry the "Signaling Connection Release Indication Cause" IE.
Intelligent UEs that can use EFD are called fast dormancy UEs, and other UEs are called non-
fast dormancy UEs. Among the preceding four types of UEs, UEs that do not send an SCRI
message (earlier than 3GPP Release 5) are called non-fast dormancy UEs and the other three
types are called fast dormancy UEs.
If EFD is not enabled, the RNC releases the signaling connection of a UE and switches the UE
to idle mode after receiving an SCRI message from the UE.
If EFD is enabled, the RNC switches a UE to idle mode or to the CELL_FACH, CELL_PCH,
or URA_PCH state after receiving an SCRI message from the UE.
For details about the SCRI message, see section 8.1.14 "Signalling connection release indication
procedure" in 3GPP TS 25.331 V10.7.0.
2.2 Benefits
This feature can reduce RNC signaling load, NodeB signaling load, and NodeB CE resource
consumption caused by intelligent UEs.
For example, after the feature is enabled, if the number of PS RAB setups decreases by 70%,
the RNC SPU load decreases by 5% to 20% and both the NodeB signaling load and CE resource
consumption decrease by 10% to 30%.
NOTE
For the BSC6900, a signaling processing unit is the SPUa, SPUb, or SPUc board.
For the BSC6910, a signaling processing unit is the EGPUa board.

3Technical Description
When there is no PS data to be transmitted, the intelligent UE sends the RNC an SCRI message
to request the UTRAN to release the signaling connection. This procedure saves power. In
addition, the UE periodically sends heartbeat messages to the core network, for example, to
check for new mails on the mail server. If the EFD feature is disabled, the RNC releases the
signaling connection and switches the UE to idle mode. In this case, sending heartbeat messages
leads to the procedures for RRC connection setups, authentication, encryption, and RAB setups.
These procedures increase the RNC signaling processing load.
EFD is introduced to decrease the RNC signaling processing load. With EFD, the RNC switches
a UE to the CELL_FACH or CELL_PCH/URA_PCH state instead of idle mode upon receiving
an SCRI message from the UE. In this case, when the UE periodically sends heartbeat messages,
the signaling procedure between the UE and RNC is simplified because the RRC connection is
maintained. As the number of signaling exchange messages decreases, significant CPU
resources can be saved for the RNC, and the UE consumes less battery power than a UE in idle
mode.
To enable the EFD feature, select the FAST_DORMANCY_SWITCH check box under the
PROCESSSWITCH(BSC6900,BSC6910) parameter in the SET URRCTRLSWITCH
command.
Figure 3-1 shows the signaling processing procedures for fast dormancy UEs before and after
EFD is enabled.
WCDMA RAN
Enhanced Fast Dormancy Feature Parameter Description 3 Technical Description

Figure 3-1 Signaling processing procedures for fast dormancy UEs before and after EFD is
enabled
After EFD is enabled, the RNC identifies which UEs can use this feature through either of the
following mechanisms:
l Using the Type Allocation Code (TAC)
This mechanism, which is not standardized, is used for the early proprietary
implementations of fast dormancy.
The international mobile equipment identity (IMEI), which consists of 14 decimal digits
and one check digit, contains TAC and SNR. TAC indicates a particular type of device that
has been approved by a national GSM/WCDMA approval body. SNR is the serial number
identifying the UE. The structure of the IMEI, which is shown as follows, is specified in
section 6.2.1 "Composition of IMEI" of 3GPP TS 23.003 V8.15.0.
TAC (8 digits) SNR (6 digits) Spare (1 digit)
When the FD_TAC_MATCH_SWITCH under the PROCESSSWITCH
(BSC6900,BSC6910) parameter is enabled, the RNC determines whether fast dormancy
UEs can use EFD based on their TACs. Specifically, upon receiving an IDENTITY
REQUEST message from a fast dormancy UE, the RNC checks whether the TAC in the
IMEI IE of the message is in the EFD list.
– If so, the UE can use EFD. Upon receiving the SCRI message from the fast dormancy
UE, the RNC switches the UE to the CELL_FACH, CELL_PCH, or URA_PCH state.
WCDMA RAN
8

– If not, the UE cannot use EFD.
To enable the UE to use EFD, run the ADD UIMEITAC command to set the TAC
(BSC6900,BSC6910) parameter to the UE's TAC, set the FastDormancy
(BSC6900,BSC6910) parameter to ON, and set the TAC_FUNC(BSC6900,BSC6910)
parameter to Fast_Dormancy.
NOTE
Some fast dormancy UEs may have compatibility issues if the RNC switches them to the CELL_FACH,
CELL_PCH, or URA_PCH state after these UEs send an SCRI message. As a result, new services cannot
be initiated. This feature was tested only on iPhones and no compatibility issue occurred.
l Checking whether the UEs comply with 3GPP Release 5 or later
To enable UEs complying with 3GPP Release 5 or later to use EFD, the RNC must switch
these UEs to the CELL_FACH, CELL_PCH, or URA_PCH state or to idle mode upon
receiving the SCRI message from them. The related operations are as follows:
1. Disable the FD_TAC_MATCH_SWITCH under the PROCESSSWITCH
(BSC6900,BSC6910) parameter. This adds the TACs of UEs that comply with 3GPP
Release 5 or later to the EFD list so that these UEs can use EFD.
2. Enable the RNC_FD_SCRI_FORCE_REL_SWITCH under the
PROCESSSWITCH2(BSC6900,BSC6910) parameter. This enables the RNC to
switch fast dormancy UEs to idle mode upon receiving an SCRI message with no
cause value from them.
3. Run the RMV UIMEITAC command to remove TACs whose TAC_FUNC
(BSC6900,BSC6910) is set to Fast_Dormancy from the EFD list.
NOTE
You can run the LST UIMEITAC command to view TACs whose TAC_FUNC
(BSC6900,BSC6910) is set to Fast_Dormancy.

4State Transitions for Fast Dormancy UEs
When EFD is disabled, upon receiving an SCRI message from a UE, the RNC releases the UE's
PS signaling connection.
When EFD is enabled, state transition procedures vary according to the UE type as follows:
l For fast dormancy UEs on the EFD list:
– The RNC switches fast dormancy UEs to idle mode to prevent compatibility issues
when the RNC receives an SCRI message where the Signaling Connection Release
Indication Cause IE is set to "UE Requested PS Data session end" and then another
SCRI message that does not include the Signaling Connection Release Indication Cause
IE.
– The RNC switches UEs from the CELL_DCH or CELL_FACH state to idle mode upon
receiving an SCRI message where the Signaling Connection Release Indication Cause
IE is excluded if the RNC_FD_SCRI_FORCE_REL_SWITCH under the
PROCESSSWITCH2(BSC6900,BSC6910) parameter in the SET
URRCTRLSWITCH command is turned on. When the RNC receives an SCRI
message where the Signaling Connection Release Indication Cause IE is set to " UE
Requested PS Data session end", the RNC switches these UEs to the CELL_FACH,
CELL_PCH, or URA_PCH state.
If this switch is turned off, the RNC switches these UEs to the CELL_FACH or
CELL_PCH/URA_PCH state upon receiving the SCRI message. Note that the
RNC_EFD_D2F_SWITCH (under OptimizationSwitch(BSC6900,BSC6910) in SET
URRCTRLSWITCH) and FD_TAC_FORCE_D2F_SWITCH (under
PROCESSSWITCH(BSC6900,BSC6910) in ADD UIMEITAC) jointly control
whether these UEs are switched to the CELL_FACH or CELL_PCH/URA_PCH state
from the CELL_DCH state.
– After PS data transmission is complete, the RNC switches a UE to CELL_FACH or
CELL_PCH/URA_PCH if the UE is in CELL_DCH and the PS inactivity timer
PsInactTmrForFstDrmDch(BSC6900,BSC6910) for EFD in CELL_DCH expires.
– After PS data transmission is complete, the RNC switches a UE to CELL_PCH/
URA_PCH if the UE is in CELL_FACH and the PS inactivity timer
PsInactTmrForFstDrmFach(BSC6900,BSC6910) for EFD in CELL_FACH expires.
The RNC_DF_2_URA_PCH_SWITCH under the PROCESSSWITCH
(BSC6900,BSC6910) parameter in the SET URRCTRLSWITCH command controls
whether the UE is switched to the CELL_PCH or URA_PCH state.
WCDMA RAN
Enhanced Fast Dormancy Feature Parameter Description 4 State Transitions for Fast Dormancy UEs
10

– The RNC does not process an SCRI message where the Signaling Connection Release
Indication Cause IE is set to "UE Requested PS Data session end" when the RNC is
processing other procedures and the SCRIWITHCAUSE_OVERLAP_SWITCH under
the OptimizationSwitch3(BSC6900,BSC6910) parameter in the SET
URRCTRLSWITCH command is turned on. Instead, the RNC preferentially
processes the ongoing procedures. After completing the ongoing procedures, the RNC
triggers the state transition procedure if the UE sends the RNC another SCRI message
or the PS inactivity timer expires.
– If a UE is switched to CELL_PCH/URA_PCH and the PS inactivity timer
PsInactTmrForPreFstDrm(BSC6900,BSC6910) for EFD in CELL_PCH/URA_PCH
expires, the RNC switches the UE to idle mode. The value of this timer should be less
than or equal to that of T305(BSC6900,BSC6910), preventing the UE from being
always in the CELL_PCH/URA_PCH state and unable to enter idle mode.
– If a UE is in CELL_PCH/URA_PCH and has data to send but the conditions for P2D/
U2D are not satisfied, the RNC instructs the UE to enter the CELL_FACH state.
– TAC-based P2D/U2D transitions. That is, when the FD_P2D_SWITCH under the
PROCESSSWITCH(BSC6900,BSC6910) parameter in the ADD UIMEITAC
command is turned on, a P2D/U2D transition starts if the UE's TAC is identical with
the TAC added to the EFD list by running the ADD UIMEITAC command and the UE
experiences uplink data transmission or has a paging response in the PS domain.
– For details about P2D/U2D transitions due to FACH congestion, see section "FACH
Congestion Control" in Flow Control Feature Parameter Description.
– If a UE is in CELL_FACH and send messages whose traffic volume is higher than
FastDormancyF2DHTvmThd(BSC6900,BSC6910), the RNC switches the UE from
CELL_FACH to CELL_DCH.
– The main factor for triggering the D2I transitions is FACH congestion. For details about
state transitions due to FACH congestion, see section "FACH Congestion Control" in
Flow Control Feature Parameter Description.
– For details about P2U/U2U/D2D/CPC/E-FACH and D2F/F2P based on 4B event state
transitions, see State Transition Feature Parameter Description.
l For UEs not on the EFD list:
– If the RNC received the SCRI, the RNC switches the UE to idle mode.
– The state transition for UEs not on the EFD list is the same as that for ordinary UEs.
For details, see State Transition Feature Parameter Description.
– For details about state transitions due to FACH congestion, see section "FACH
Congestion Control" in Flow Control Feature Parameter Description.
NOTE
In the preceding descriptions, assume that single PS services are referred to. Upon receiving an SCRI
message from a UE processing CS+PS BE combined services, the RNC first releases the UE's PS signaling
connection. When the CS service is released, the RNC releases the UE's RRC connection.
UEs with a specified TAC cannot enter the CELL_PCH or URA_PCH state if you set the parameters in
the ADD UIMEITAC command as follows:
l Specify the TAC(BSC6900,BSC6910) parameter.
l Set the TAC_FUNC(BSC6900,BSC6910) parameter to Special_User_Enhance.
l Select the PCH_DISABLED_SWITCH check box under the SpecUserFunctionSwitch
(BSC6910,BSC6900) parameter.

D2P/D2U indicates a transition from CELL_DCH to CELL_PCH/
URA_PCH, F2P/F2U from CELL_FACH to CELL_PCH/URA_PCH, and
D2F from CELL_DCH to CELL_FACH.
The RNC starts the PS inactivity timer for fast dormancy when inactivity on
PS data is detected.
l PsInactTmrForFstDrmDch(BSC6900,BSC6910) specifies the PS
inactivity timer for CELL_DCH.
l PsInactTmrForFstDrmDch(BSC6900,BSC6910) specifies the PS
inactivity timer for CELL_FACH.
l PsInactTmrForPreFstDrm(BSC6900,BSC6910) specifies the PS
inactivity timer for CELL_PCH/URA_PCH.
If the UE is a fast dormancy UE and is not processing CS services, when
the PS inactivity timer for fast dormancy expires or the RNC receives an
SCRI message from the UE, the UE changes states as follows:
For a UE in the CELL_DCH state:
l If the RNC_EFD_D2F_SWITCH under the OptimizationSwitch
(BSC6900,BSC6910) parameter in the SET URRCTRLSWITCH
command is turned on or the FD_TAC_FORCE_D2F_SWITCH under
the PROCESSSWITCH(BSC6900,BSC6910) parameter in the ADD
UIMEITAC command is turned on, the RNC triggers a D2F transition.
l If the RNC_EFD_D2F_SWITCH under the PROCESSSWITCH
command is turned off and the FD_TAC_FORCE_D2F_SWITCH
under the PROCESSSWITCH(BSC6900,BSC6910) parameter in the
ADD UIMEITAC command is turned off, the RNC triggers a D2P/D2U
transition.
For a UE in the CELL_FACH state, the RNC trigger an F2P/F2U state
transition.
l The RNC_DF_2_URA_PCH_SWITCH under the PROCESSSWITCH
command controls whether the UE is switched to the CELL_PCH or
URA_PCH state.
If this switch is turned on, the RNC initiates D2U or F2U state transitions.
If this switch is turned off, the RNC initiates D2P or F2P state transitions.
D2I//F2I D2I/F2I indicates a transition from CELL_DCH/CELL_FACH to idle.
The RNC initiates D2I or F2I state transitions upon receiving an SCRI
message where the Signaling Connection Release Indication Cause IE is
excluded if the RNC_FD_SCRI_FORCE_REL_SWITCH under the
PROCESSSWITCH2(BSC6900,BSC6910) parameter in the SET
URRCTRLSWITCH command is turned on.
D2I is also used for FACH congestion. For details about state transitions due
to FACH congestion, see section "FACH Congestion Control" in Flow
Control Feature Parameter Description.
WCDMA RAN

Type Description
P2I/U2I P2I/U2I indicates a transition from CELL_PCH/URA_PCH to idle.
If the UE is in the CELL_PCH/URA_PCH state, when the PS inactivity timer
for fast dormancy (specified by PsInactTmrForPreFstDrm
(BSC6900,BSC6910) expires, the RNC releases the UE's RRC connection
and then the UE enters idle mode.
P2D
U2D
P2D/U2D indicates a transition from CELL_PCH/URA_PCH to

turned on, a P2D/U2D transition starts if the UE's TAC is identical with
the TAC added to the EFD list by running the ADD UIMEITAC
command and the UE experiences uplink data transmission or has a paging
response in the PS domain.
l For details about P2D/U2D transitions due to FACH congestion, see
section "FACH Congestion Control" in Flow Control Feature Parameter
Description.
P2F
U2F
P2F/U2F indicates a transition from CELL_PCH/URA_PCH to
CELL_FACH.
When the UE has data to send and the condition for P2D/U2D is not satisfied,
the RNC instructs the UE to enter the CELL_FACH state.
F2D F2D indicates a transition from CELL_FACH to CELL_DCH.
When a fast dormancy UE is in the CELL_FACH state and sends messages
whose traffic volume is higher than the FastDormancyF2DHTvmThd
(BSC6900,BSC6910), the RNC switches the UE from CELL_FACH to
CELL_DCH. The FastDormancyF2DHTvmThd(BSC6900,BSC6910) is a
new threshold of event 4a for fast dormancy UEs. This threshold is generally
set to a value greater than the traffic volume of most heartbeat messages to
prevent state transitions from being triggered by small-sized heartbeat
messages.

6Network Impact
System Capacity
This feature can reduce RNC signaling load, NodeB signaling load, and NodeB CE resource
consumption caused by intelligent UEs. The feature gains depend on network coverage,
proportion of intelligent UEs, and traffic model.
Network Performance
This feature has the following impacts on network performance:
l Reduced RRC connection setup success rate (The RRC connection setup failure rate does
not increase.)
– On live networks, the service-related RRC connection setup success rate is higher than
the non-service-related RRC connection setup success rate. After this feature is enabled,
the number of service-related RRC connection setup attempts significantly decreases
and the number of non-service-related RRC connection setup attempts slightly
decreases. A possible result of this is that the total RRC connection setup success rate
decreases but the number of RRC connection failures does not increase.
– The signaling exchange success rate in poor coverage areas is generally lower than that
in good coverage areas. After this feature is enabled, the number of RRC connection
setup attempts slightly decreases in poor coverage areas and the number of RRC
connection setup attempts significantly decreases in good coverage areas. A possible
result of this is that the total RRC connection setup success rate decreases but the number
of RRC connection setup failures does not increase.
l Reduced PS RAB setup success rate
The calculation formula for the PS RAB setup success rate was corrected, as described in
section 7.4.1 Requirements. According to the operation and maintenance experience of
live networks, the PS RAB setup success rate of some fast dormancy UEs is higher than
the average level of the entire network. After this feature is enabled, the number of PS RAB
setup attempts significantly decreases. As a result, the total PS RAB setup success rate may
decrease.
l Reduced paging success rate
After this feature is enabled, a large number of UEs are switched to the CELL_PCH or
URA_PCH state. As a result, the number of paging attempts in idle mode significantly
decreases, but the original paging failures cannot be eliminated. A possible consequence

Enhanced Fast Dormancy Feature Parameter Description 6 Network Impact
17

of this is that the paging success rate in idle mode decreases. The original paging failures
may be caused by the following:
– UEs that are dropped from the network or abnormally shut down
– Poor coverage
– Multiple RNCs sharing the same LAC or RAC
l Longer FACH congestion duration
After this feature is enabled, the number of UEs in the CELL_FACH state increases, the
traffic volume on the FACH increases. As a result, the FACH congestion duration may
increase.
l Increased PS call drop rate
The calculation formula for the PS call drop rate was corrected, as described in section
7.4.1 Requirements. Before this feature is enabled, the UE may be switched to idle mode
because it has no PS data transmission before TRB reset. After this feature is enabled, the
online duration of UEs performing PS services increases so that there may be more TRB
resets before the PS User Inactive Detecting Timer expires. As a result, PS call drops occur.
Therefore, if there are a large number of call drops caused by TRB resets on the live network
before this feature is enabled, the PS call drop rate may increase after this feature is enabled.
l Increased HSDPA call drop rate
The calculation formula for the HSDPA call drop rate was corrected, as described in section
7.4.1 Requirements. After this feature is enabled, the HSDPA call drop rate may still
increase.
Before this feature is enabled, the HSDPA service is normally released if the UE has no
data to transmit. Then, if the UE has data to transmit (even only a small amount of data),
the UE is switched to the CELL_DCH state. After this feature is enabled, a large number
of UEs are switched to the CELL_PCH or URA_PCH state. Afterward, the UEs only need
to be switched to the CELL_FACH state if there is a small amount of data to transmit. As
a result, the denominator in the calculation formula for the HSDPA call drop rate decreases.
After EFD is enabled, the actual HSDPA service duration basically remains unchanged.
As a result, the total number of abnormal HSDPA service releases has few changes. In
summary, the HSDPA call drop rate increases after EFD is enabled.

7Engineering Guidelines
7.1 When to Use Enhanced Fast Dormancy
The EFD feature is recommended for scenarios where the proportion of intelligent UEs is high,
leading to a high CPU load on control-plane board in the RNC and on baseband processing
boards in the NodeB. This feature reduces the Uu, Iu, and Iub signaling, uplink and downlink
channel element (CE) consumption, and CPU load.
7.2 Required Information
None
7.3 Planning
7.3.1 RF Planning
None
7.3.2 Network Planning
It is good practice to maintain load balancing among all frequencies in the network when using
this feature. If the network is a service-layered network as follows, set Wait RB reconfiguration
response timer and RL restoration timer in the SET USTATETIMER command to 11000
and 15000, respectively. This reduces the number of call drops for fast dormancy UEs in the
CELL_FACH or CELL_PCH state.
l F1 carries R99 services.
l F2 carries HSPA services.
l F2 does not allow UEs in the idle, CELL_FACH, or CELL_PCH state to camp on.

l Calculation Formula Correction for the Call Drop Rate
Before EFD is enabled, if the UE has no data to transmit for a specified period of time, it
will be switched from connected mode to idle mode. After EFD is enabled, if the UE has
no data to transmit for a specified period of time, it will be switched from the CELL_FACH
or CELL_DCH state to the CELL_PCH or URA_PCH state instead of being switched to
idle mode. From the perspective of user experience, the UE has no data to transmit in idle
mode, CELL_PCH, and URA_PCH. All scenarios in which the UE should be switched
from CELL_DCH to idle mode, CELL_PCH, or URA_PCH are considered PS service
release scenarios. For details, see Figure 7-1, Figure 7-2, and Figure 7-3.

release before EFD is enabled
Figure 7-2 UEs with no data transmission being switched to CELL_PCH/URA_PCH after
EFD is enabled
Figure 7-3 PS service release scenarios
From the perspective of user experience, switching to CELL_PCH/URA_PCH after EFD
is enabled is equivalent to switching to idle mode through normal release before EFD is
enabled. Therefore, the calculation formula for the PS call drop rate is changed to the
following:
– The PS call drop rate measures the ratio of the number of abnormal PS service releases
to the total number of normal and abnormal PS service releases. Its calculation formula
is changed to the following:
PS Call Drop Ratio with PCH (Cell) = [(VS.RAB.AbnormRel.PS –
VS.RAB.AbnormRel.PS.PCH – VS.RAB.AbnormRel.PS.D2P –

VS.DCCC.Succ.F2P + VS.DCCC.Succ.D2U + VS.DCCC.Succ.F2U)] x 100%
– The PS R99 call drop rate measures the ratio of the number of abnormal PS R99 service
releases to the total number of normal and abnormal PS R99 service releases. Its
calculation formula is changed to the following:
PS R99 Call Drop Ratio with PCH (Cell) =
[(VS.RAB.AbnormRel.PSR99 – VS.RAB.AbnormRel.PS.PCH –
VS.RAB.AbnormRel.PS.R99D2P –
VS.RAB.AbnormRel.PS.F2P)/(VS.RAB.AbnormRel.PSR99 +

– The HSDPA call drop rate measures the ratio of the number of abnormal HSDPA service
releases to the total number of normal and abnormal HSDPA service releases. Its
HSDPA Service Drop Ratio with PCH (Cell) = [(VS.HSDPA.RAB.AbnormRel –
VS.HSDPA.RAB.AbnormRel.H2P)/(VS.HSDPA.RAB.AbnormRel +
VS.HSDPA.RAB.NormRel + VS.HSDPA.HHO.H2D.SuccOutIntraFreq +
VS.HSDPA.HHO.H2D.SuccOutInterFreq + VS.HSDPA.H2D.Succ +
VS.HSDPA.H2F.Succ + VS.HSDPA.H2P.Succ)] x 100%
– The HSUPA call drop rate measures the ratio of the number of abnormal HSUPA service
releases to the total number of normal and abnormal HSUPA service releases. Its
HSUPA Call Drop Ratio with PCH (Cell) = [(VS.HSUPA.RAB.AbnormRel –
VS.HSUPA.RAB.AbnormRel.E2P)/(VS.HSUPA.RAB.AbnormRel +
VS.HSUPA.RAB.NormRel + VS.HSUPA.HHO.E2D.SuccOutIntraFreq +
VS.HSUPA.HHO.E2D.SuccOutInterFreq + VS.HSUPA.E2F.Succ +
VS.HSUPA.E2D.Succ + VS.HSUPA.E2P.Succ)] x 100%
l Calculation Formula Correction for the PS RAB Setup Success Rate
After EFD is enabled, a large number of UEs will be switched to the CELL_PCH or
URA_PCH state. Then, a large number of UEs will be switched from CELL_PCH or
URA_PCH to CELL_FACH or CELL_DCH to establish PS services, instead of releasing
PS RAB setup and then reinitiating PS RAB setup. From the perspective of user experience,
RAB setup, P2F, and P2D are all processes in which UEs initiate services. Therefore, the
calculation formula for the PS RAB setup success rate should be corrected. The PS RAB
setup success rate measures the ratio of the number of successful PS service initiations to
the number of attempted PS service initiations. Its calculation formula is changed to the
following:
PS RAB Setup Success Ratio with PCH (Cell) = [(VS.RAB.SuccEstabPS.Cell +
VS.DCCC.P2F.Succ + VS.DCCC.URAP2F.Succ + VS.DCCC.P2D.Succ +
VS.DCCC.URAP2D.Succ)/(VS.RAB.AttEstabPS.Cell + VS.DCCC.P2F.Att +
VS.DCCC.URAP2F.Att + VS.DCCC.P2D.Att + VS.DCCC.URAP2D.Att)] x 100%
l Adding a Second S-CCPCH
After EFD is enabled, both the number of UEs in the CELL_FACH state and the traffic
volume on the FACH increase. As a result, it is possible that the user plane on the FACH
is congested and the RRC connection setup fails. Therefore, you need to add an S-CCPCH
dedicated to theFACH to alleviate FACH congestion.
WCDMA RAN
22

– If there is only one S-CCPCH on the network, it is recommended that you add a second
S-CCPCH before enabling EFD.
– Add the second S-CCPCH at least three days before enabling EFD, because the addition
takes a long time.
– Add the second S-CCPCH during off-peak hours (for example, in the early morning)
because cells need to be deactivated, which interrupts services.
– After the second S-CCPCH is added, system information on the UE side may not be
updated because the Value Tag saved on the UE is consistent with that carried in the
currently broadcast system information. As a result, the UE does not know that the S-
CCPCH has changed, thereby affecting the RRC connection setup success rate.
According to section 8.1.1 "Broadcast of system information" in 3GPP TS 25.331, the
longest period during which system information is saved on the UE is six hours. When
the longest period is exceeded, the UE reads system information again. Therefore, it
takes six hours for the RRC connection setup success rate to restore to normal. To avoid
this problem, you need to enable the
CELL_SIB_NOT_UPD_NCELL_CHG_SWITCH. If this switch is enabled, system
information is not updated in the current cell when neighboring cells are being activated
or deactivated.
For details about adding a Second S-CCPCH, see section (Mandatory) Adding a Second
S-CCPCH.
l Modify the Iu-PS activity factor.
1. Run the RNC MML command ADD TRMFACTOR to select an unused FTI and set
the activity factor to 10 for all services.
2. Run the RNC MML command MOD ADJMAP to index all Iu-PS FTIs to the
preceding FTI.
3. Run the RNC MML command MOD ADJMAP to set the activity factor to 10 for

the EFD function switch.
l Enabling the state transition switch for PS services
Step 1 Run the RNC MML command SET UCORRMALGOSWITCH to select the
DRA_PS_BE_STATE_TRANS_SWITCH check box under the Dynamic Resource
Allocation Switch parameter.
Step 2 For newly deployed networks, run the RNC MML command SET
UCORRMALGOSWITCH to select the DRA_HSDPA_STATE_TRANS_SWITCH,
DRA_HSUPA_STATE_TRANS_SWITCH, and
DRA_PS_NON_BE_STATE_TRANS_SWITCH check boxes under the Dynamic Resource
Allocation Switch parameter.
For existing networks, retain the original settings for the
DRA_HSDPA_STATE_TRANS_SWITCH, DRA_HSUPA_STATE_TRANS_SWITCH,
and DRA_PS_NON_BE_STATE_TRANS_SWITCH check boxes under the Dynamic
Resource Allocation Switch parameter.
----End
l Activating fast dormancy-related parameters
Step 1 Run the RNC MML command SET UCONNMODETIMER to set the Timer 323 parameter
to D0.
WCDMA RAN
45

Step 2 Run the RNC MML command SET URRCTRLSWITCH to deselect the
FD_TAC_MATCH_SWITCH check box under the Process switch parameter, so that 3GPP
Release 5 and later UEs can use the EFD feature.
Step 3 Run the RNC MML command SET URRCTRLSWITCH to select the
RNC_FD_SCRI_FORCE_REL_SWITCH check box under the Process Control Switch 2
parameter.
RNC_EFD_D2F_SWITCH check box under the Optimization Switch parameter, so that the
RNC performs the D2F (instead of D2P) procedure on UEs that support fast dormancy.
Step 5 Run the RNC MML command SET UPSINACTTIMER to set the FAST DORMANCY
USER T1 in CELL_DCH parameter to 2.
USER T1 in CELL_FACH parameter to 5.
USER T1 in CELL_PCH parameter to 1800.
Step 8 Run the RNC MML command SET UUESTATETRANS to set the Fast Dormancy User
FACH/E_FACH2DCH/HSPA 4A Threshold parameter to D512.
Step 9 Run the RNC MML command SET UDPUCFGDATA to set the Paging Preemption Switch
parameter to ON.
RNC_PS_QUERY_UE_IMEI_SWITCH check box under the Process Control Switch 2
parameter.
Step 11 To disallow fast dormancy UEs to be switched to the URA_PCH state when EFD is enabled,
run the RNC MML command SET URRCTRLSWITCH to deselect the
RNC_DF_2_URA_PCH_SWITCH check box under the Process switch parameter.
----End
If you have to allow fast dormancy UEs to be switched to the URA_PCH state when EFD is
enabled, split the URA and run the RNC MML command SET URRCTRLSWITCH to select
the RNC_DF_2_URA_PCH_SWITCH check box under the Process switch parameter.
----End
(Optional) Activating the FACH Parameter Optimization Strategy
After EFD is enabled, both the number of UEs in the CELL_FACH state and the traffic volume
on the FACH increase. As a result, the FACH may be congested, resulting in call drops.
Therefore, the FACH parameter optimization strategy needs to be activated.
l Optimization parameters for the number of UEs in the CELL_FACH state
Step 1 Run the RNC MML command SET UCACALGOSWITCH to select the
FACH_60_USER_SWITCH check box under the CAC algorithm switch parameter to enable
the Switch for Allowing a Maximum of 60 UEs Carried on the FACH.
Step 2 Run the RNC MML command SET UCORRMPARA to deselect the
PERFENH_FACH_CONG_D2IDLE_SWITCH check box under the Performance
WCDMA RAN
46

Enhancement Switch 1 parameter. In this way, D2I is not triggered when the number of
CELL_FACH UEs reaches the upper threshold.
Step 3 Run the RNC MML command SET URRCTRLSWITCH to select the P2D_SWITCH check
box under the Optimization Switch parameter. In this way, P2D is triggered when the number
of CELL_FACH UEs reaches the upper threshold.
----End
l Other FACH optimization parameters
RNC_TVM_BASED_P2D_SWITCH check box under the Process Control Switch 3
parameter to enable the TVM-based P2D Switch.
Step 2 Run the RNC MML command SET UCORRMPARA to select the
PERFENH_PSTRAFFIC_P2H_SWITCH check box under the Performance Enhancement
Switch parameter to enable the switch for P2H triggered by PS services.
PERFENH_P2D_FAIL_RETRY_SWITCH check box under the Performance
Enhancement Switch 1 parameter, so that DRD and channel fallback are performed if P2D
fails.
RNC_F2D_RLC_SUSPEND_SWITCH check box under the Process Control Switch 3
parameter to enable the switch for RLC data transmission suspension during downlink F2D.
Step 5 Enable the RLC data transmission suspension function in the uplink during F2D.
1. Run the RNC MML command SET UUESTATETRANS to set the Tx Interruption After
Trigger parameter to D2000, which indicates the duration during which UEs are prohibited
from transmitting data over the RACH after reporting 4A measurement reports and
triggering the procedure for the CELL_FACH-to-CELL_DCH state transition.
2. Run the RNC MML command SET UCORRMPARA to select the
PERFENH_TX_INTERRUPT_AFT_TRIG_SWITCH check box under the
Performance Enhancement Switch parameter to enable the switch for including the Tx
interruption after trigger IE in the uplink 4A traffic volume measurement control message.
CMP_F2P_PROCESS_OPTIMIZATION_SWITCH check box under the Compatibility
Switch parameter.
----End
(Optional) Activating the Combined Services Parameter Optimization Strategy
After EFD is enabled, there are more scenarios in which CS+PS combined services exist.
However, the CS call drop rate in the combined services is higher than the single-CS call drop
rate. As a result, the total CS call drop rate increases. Therefore, you need to activate the
following optimization parameters for combined services:
MAP_CSPS_PS_UL_USE_DCH_SWITCH check box under the Service Mapping Strategy
WCDMA RAN
47

Switch parameter, so that PS services in combined services can be carried over the DCH in the
uplink.
MAP_CSPS_PS_DL_USE_DCH_SWITCH check box under the Service Mapping Strategy
Switch parameter, so that PS services in combined services can be carried over the DCH in the
downlink.
Step 3 Run the RNC MML command SET UFRC to set the Upper limit of UL BE data rate in AMR
services parameter to D8.
Step 4 Run the RNC MML command SET UFRC to set the Upper limit of DL BE data rate in AMR
services parameter to D8.
----End
The combined services parameter optimization strategy reduces the CS call drop rate but affects
the experience of users performing the PS service in combined services. To guarantee the
experience of users performing the PS service in combined services during a CS call, follow the
suggestions in section 11.1.1 "When to Use Bearer Channel Type and Access Rate Control Policy
for PS BE Services During a Setup of Combined Services" in Enhanced Combined Services
Feature Parameter Description.
(Optional) Activating Other Parameter Optimization Strategies
AMR_F2D_OVERLAP_CELLUPT_SWITCH check box under the Optimization Switch
parameter.
PERFENH_F2P_LIMIT_WITH_CS_IU_CON_SWITCH check box under the
Performance Enhancement Switch 1 parameter.
Step 3 Run the RNC MML command MOD UCELLMEAS to set the FACH Meas Occasion Cycle
Len Coefficient parameter. If the FACH Measurement Indicator parameter is set to
NOT_REQUIRE on the live network, do not change the setting of the FACH Meas Occasion
Cycle Len Coefficient parameter. Otherwise, set FACH Meas Occasion Cycle Len
Coefficient to 6. (Note that the settings of Inter-freq and Inter-RAT Meas Ctrl Info Ind and
FACH Measurement Indicator should be the same as the original settings.)
RB_SETUP_F2D_USE_AM_RLC_SWITCH check box under the Optimization Switch4
parameter, so that AM is used when the UE in the CELL_FACH state delivers the CS RB SETUP
message.
RB_RECFG_F2D_USE_AM_RLC_SWITCH check box under the Optimization Switch4
parameter, so that AM is used when the UE in the CELL_FACH state delivers the RADIO
BEARER RECONFIGURATION message.
RRC_CELLFACH_DL_TRB_RESET_TO_F2D_SWITCH check box under the Process
Control Switch 4 parameter.
WCDMA RAN
48

SEND_UE_CAP_ENQ_RELOC_CCH_SWITCH check box under the Improvement
Switch parameter.
Step 8 Run the RNC MML command SET UNBMPARA to select the
PERFENH_CRNTI_OPT_SWITCH check box under the Performance Switch parameter to
enable the C-RNTI allocation mechanism optimization switch.
Step 9 Run the RNC MML command SET UDPUCFGDATA to set the RLC SDU Retransmission
parameter to ON to enable the RLC SDU retransmission switch.
CMP_F2D_RLC_ONESIDE_REBUILD_SWITCH check box under the Compatibility
Switch2 parameter, so that the RLC entity can be re-established in only the uplink or downlink
during the F2D state transition.
RB_CU_FAIL_RRC_REL_CELL_OPT_SWITCH check box under the Optimization
Switch5 parameter, so that the UE can receive the RRC connection release message if the RNC
receives the cell update message with the cause value "cell reselection" during the D2F
procedure.

7.4.6 Activation Observation
Activation Observation Through Uu Interface Message Tracing
Step 1 Run the RNC MML command DSP LICUSAGE to query the state of the license for this feature.
If the result shown in Figure 7-5 is returned, the license for this feature has been configured.
Figure 7-5 Status of the Enhanced Fast Dormancy license
Step 2 Initiate Uu interface message tracing on the RNC LMT.
Step 3 Use an intelligent UE whose that its IMEI TAC has been added into EFD list to set up a PS
service in the CELL_DCH state. For example, use the UE to browse a Web page.
If the RRC_RB_SETUP message shown in Figure 7-6 is traced, the UE is in the CELL_DCH
state.

Activation Observation Through Counters
You can determine whether the EFD function has taken effect by observing the
VS.DCCC.FastDormUe.DF2P.Att and VS.DCCC.FastDormUe.DF2P.Succ counters. If the
values of these two counters are not 0, the EFD function has taken effect.
7.4.7 Deactivation
Deactivating the EFD Function
l Disable the EFD function switch.
Run the RNC MML command SET URRCTRLSWITCH to deselect the
FAST_DORMANCY_SWITCH check box under the Process switch parameter to
disable the EFD function switch.
l Restore other EFD-related parameters to the settings before feature activation.
Rolling Back the Double S-CCPCH Strategy to the Single S-CCPCH Strategy
Generally, it is not recommended that you roll back the double S-CCPCH strategy to the single
S-CCPCH strategy. If you have to, perform the following steps:
After the second S-CCPCH is added, system information on the UE side may not be updated
because the Value Tag saved on the UE is consistent with that carried in the currently broadcast
system information. As a result, the UE does not know that the S-CCPCH has changed, thereby
affecting the RRC connection setup success rate. Generally, the UE will update system
information six hours later, and the RRC connection setup success rate can be restored to normal
by then. To avoid this problem, you need to enable the
CELL_SIB_NOT_UPD_NCELL_CHG_SWITCH. If this switch is enabled, system
information is not updated in the current cell when neighboring cells are being activated or
deactivated.
Step 1 Before rolling back the double S-CCPCH strategy to the single S-CCPCH strategy, run the RNC
MML command SET UNBMPARA to select the
parameter to enable the Neighboring Cell Status Change Not Update SIB Switch.
Step 2 Run the script that is used to roll back the double S-CCPCH strategy to the single S-CCPCH
strategy for all cells. (The following describes the parameter configurations separately: when
CBS is enabled and when CBS is disabled.)
Step 3 Run the RNC MML command SET UNBMPARA to deselect the
parameter to disable the Neighboring Cell Status Change Not Update SIB Switch.

RB_RLREEST_AM_TRB_RLC_REEST_SWITCH
(Reestablish TRB RLC in AM for RL Reestablish)
When radio link (RL) reestablishment is triggered
during RB related procedures, the encryption
parameters configured for the RNC become
inconsistent with those configured for the UE if the
following conditions are met: The RB related procedure
succeeds; the TRB is in acknowledged mode (AM) or
the size of the RLC PDU changes in AM; the RLC entity
is not reestablished for the TRB. As a result, data
transmission fails on the user plane, and the TRB is
reset. This parameter specifies whether the RNC
reestablishes the RLC entity for TRBs that use AM in
the preceding scenario. 1: This switch is turned on. The
RLC entity is reestablished for the TRB in the preceding
scenario. 0: This switch is turned off. The RLC entity is
not reestablished for the TRB in the preceding scenario.

reconfigured. As a result, after the RL is reestablished,
data transmission fails on the user plane because the
encryption parameters configured for the RNC are
inconsistent with those configured for the UE. Services
are interrupted. This parameter specifies whether the
RNC reestablishes the RL for TRBs that use UM in the

ITCH: Whether the RNC makes an admission decision
on RAB setup when the resources required by RAB
setup for a low-rate PS user do not outnumber the
resources used for RRC connection setup. When this
switch is turned on, the RNC makes admission decisions
on both CS and PS RAB setups. For related admission
thresholds, see the [CMD]ADD UCELLCAC[/CMD]
command. When this switch is turned off, the RNC
makes admission decisions only on CS service
procedures. That is, the RNC always admits PS service
requests. A low-rate PS user is a user whose SF
corresponding to RAB setup is equal to or larger than
the SF reserved for a handover. The SF reserved for a

Whether the number of FACH UEs in a cell is limited
by the CELL_FACH UE number specification. When
this switch is set to on, the number of FACH UEs in a
cell is limited not only by the FACH UE number
specification but also by the CELL_FACH UE number
specification (CELL_FACH UEs include both E-FACH
UEs and FACH UEs). That is, the total number of
FACH UEs and E-FACH UEs in a cell cannot exceed
the CELL_FACH UE number specification. When this
switch is set to off, the number FACH UEs in a cell is
only limited by the FACH UE specification. 28.
PERFENH_RELOCINUSER_LDRPRE_OPT_SWIT
CH(Optimization Switch for Static Relocation User
Selection for LDR and Preemption): Whether to
optimize the user selection algorithm for LDR and
preemption. When this switch is set to on, the user
selection algorithm for LDR and preemption is
optimized. That is, the actual priority of static relocation
UEs is used for LDR and preemption, which makes the
user priority recognition more accurate. When this
switch is turned off, default user priority is used for LDR
and preemption. 29.
PERFENH_SOFTERHO_CE_OPT_SWITCH:
Calculation method of consumed CE resources. If this
parameter is set to ON, the RNC correctly calculates the
consumed CE resources. If this parameter is set to OFF,
the CE resources consumed on the link that is deleted
after a soft handover are not calculated. As a result, the
available CE resources increase and excess users access

PERFENH_LCGCE_RSRC_OPT_SWITCH: LCG CE
resource optimization switch for preempted UEs. When
this switch is set to on, the RNC correctly maintains the
LCG CE resources used by a UE after an RRC
connection setup. If the UE is preempted, these
resources are provided to the preempting UE. When this
switch is set to off, the RNC cannot update the LCG CE
resources used by a UE in time, which leads to incorrect
resource maintenance and affects the calculation of
resources for preemption. 31.

PERFENH_SRB_OVER_HSDPA_DOFF_OPT_SWI
TCH: Whether to optimize the Default DPCH Offset
Value (DOFF) allocation algorithm for a specified UE.
This switch is set to on by default. When this switch is

H: Whether the last vacant SF16 code is used as the HS-
PDSCH code when HSDPA has been activated. When
this switch is turned on and HSDPA has been activated,
no matter whether the last SF16 code is vacant, the RNC
repeatedly attempts to allocate this code to the HS-
PDSCH This improves the SF spreading code usage. If
the HS-PDSCH setup fails, the RNC allocates the last
vacant SF16 code to the HS-PDSCH. When this switch
is turned off and HSDPA has been activated, the RNC
allocates the last vacant SF16 code first to the HS-
PDSCH. This improves the HSDPA activation
efficiency. 14.
PERFENH_OLC_REJ_F2DDCCC_SWITCH:
Whether to prohibit the DCCC-triggered state transition
from CELL_FACH to CELL_DCH (F2D for short)

Whether the channel codes released by a common
channel are reserved during reestablishment of the
common channel so that the reestablished common
channel can use the same channel codes after cell setup.
When this switch is turned on, the channel codes
released by a common channel are reserved during
reestablishment of the common channel. That is, the
reestablished common channel uses the same channel

the channel codes released by a common channel are not
reserved during reestablishment of the common
channel. That is, the reestablished common channel
uses different channel codes after cell setup. 19.
ITCH: Whether the RNC makes an admission decision
on RAB setup when the resources required by RAB
setup for a low-rate PS user do not outnumber the
resources used for RRC connection setup. When this
switch is turned on, the RNC makes admission decisions
on both CS and PS RAB setups. For related admission
thresholds, see the [CMD]ADD UCELLCAC[/CMD]
command. When this switch is turned off, the RNC
makes admission decisions only on CS service
procedures. That is, the RNC always admits PS service
requests. A low-rate PS user is a user whose SF
corresponding to RAB setup is equal to or larger than
the SF reserved for a handover. The SF reserved for a
handover can be configured by the UlHoCeResvSf and

cell is limited not only by the FACH UE number
specification but also by the CELL_FACH UE number
specification (CELL_FACH UEs include both E-FACH
UEs and FACH UEs). That is, the total number of
FACH UEs and E-FACH UEs in a cell cannot exceed
the CELL_FACH UE number specification. When this

are communicating with each other. So RNC creates this
switch. when it is checked, RNC is auto-adaptive to
accept the CR2284R1 according to UE version
information. The principles that RNC judges UE
whether to accept the CR2284R1 are as follows: R5 and

START LIST value from RB SETUP
COMPLETE,RNC figures that UE accepts the CR;
R99/R4 UE, if it only receives the START value from
RB SETUP COMPLETE,RNC figures that UE does not
accept the CR; when it is not checked, whether RNC
accept the CR or not is according to
CR2284R1_SWITCH. The relations between these two
switches CR2284R1_SWITCH and
CR2284R1_COMPATIBLE_SWITCH are as follows:
1: This switch is turned on. RNC is self-compatible, so

switch must be also on before this switch takes effect.
12. DRA_HSUPA_STATE_TRANS_SWITCH: When
the switch is on, the status of the UE RRC that carrying
HSUPA services can be changed to CELL_FACH at the
RNC. If a PS BE service is carried over the E-DCH, the
switch PS_BE_STATE_TRANS_SWITCH should be

DRA_IP_SERVICE_QOS_SWITCH: Switch of the
algorithm for increasing the quality of subscribed
services. When this parameter is set to ON, the service
priority weight of the subscriber whose key parameters
(IP Address, IP Port, and IP Protocol Type) match the
specified ones can be adjusted. In this way, the QoS is
improved. 14.
DRA_PS_BE_STATE_TRANS_SWITCH: When this
switch is turned on, UEs can be transited among the
CELL_DCH, CELL_FACH, CELL_PCH, and
URA_PCH states when they are processing PS BE
services. 15.
DRA_PS_NON_BE_STATE_TRANS_SWITCH:
When this switch is turned on, UEs can be transited
between the CELL_DCH and CELL_FACH states
when they are processing real-time PS services. 16.
DRA_R99_DL_FLOW_CONTROL_SWITCH:
Under a poor radio environment, the QoS of high speed
services drops considerably and the TX power is overly
high. In this case, the RNC can set restrictions on low
data rate transmission formats based on the transmission
quality, thus lowering traffic speed and TX power.
When the switch is on, the R99 downlink flow control
function is enabled. 17.
DRA_THROUGHPUT_DCCC_SWITCH: When the
switch is on, the DCCC based on traffic statistics is
supported over the DCH. 18.
DRA_VOICE_SAVE_CE_SWITCH: when the switch
is on, the TTI selection based on the voice service type
(including VoIP and CS over HSPA) is supported when
the service is initially established. 19.

DRA_CSPS_NO_PERIOD_RETRY_SWITCH:
Whether to prohibit channel retries for CS and PS
combined services. When this switch is turned on,
channel retries are prohibited for CS and PS combined
services. When this switch is turned off, channel retries
are allowed for CS and PS combined services. 21.
DRA_SMART_FAST_STATE_TRANS_SWITCH:
Whether to activate the fast state transition algorithm.
When this switch is turned on, the RNC identifies UEs
supporting fast state transition and then quickly transits
the UEs from CELL_DCH to CELL_FACH. 22.
DRA_PCH_UE_SMART_P2D_SWITCH: Whether to
activate the algorithm for smart PCH-to-DCH state
transition specific to UEs in the CELL_PCH or
URA_PCH state. When this switch is turned on, the
RNC identifies UEs supporting smart PCH-to-DCH
state transition and then transits the UEs from
CELL_PCH or URA_PCH to CELL_DCH. 23.
DRA_BASE_RES_BE_TTI_INIT_SEL_SWITCH:
Whether initial TTI selection is allowed for
differentiated BE services based on fairness 0: This
switch is turned off. The TTI is selected according to
the original algorithm. 1: This switch is turned on. In
the dynamic TTI adjustment algorithm for
differentiated BE services based on fairness, HSUPA
UEs use 10-ms TTI if the RTWP, occupied Iub
bandwidth, or consumed CE resources are congested.
24.
H: Whether to activate the coverage-based initial TTI
selection algorithm specific to BE services. When this
switch is turned on and conditions on 2 ms TTI specific
to BE services has been met, the RNC determines uplink
coverage wideness of specific cells based on the Ec/N0
values reported by UEs during RRC connection. If the
uplink coverage of the cells is weak, the RNC allocates
a 10 ms TTI to BE services as their initial TTI. 25.
DRA_F2U_SWITCH: Whether to enable state
transition from CELL_FACH to URA_PCH.When this
switch is turned on, a UE can directly move from the
CELL_FACH to URA_PCH state. When this switch is
turned off, a UE must move from the CELL_FACH to
CELL_PCH and then to URA_PCH state. 26.

ITCH: Whether to use the algorithm of UE location-
based HSUPA scheduling. When this switch is turned
on, the algorithm is used. When this switch is turned off,
the algorithm is not used. 2.
PERFENH_HRETRY_OPT_SWITCH: Whether the
algorithm of channel retry optimization takes effect.
When this switch is turned on, the algorithm takes effect
and channel retries are triggered in all scenarios where
the preconditions are met. However, turning on this
switch may increase the CPU usage. When this switch
is turned off, the algorithm does not take effect. 3.
PERFENH_IUR_CSPS_RELOC_OPT_SWITCH:
Static relocation policy for CS and PS BE combined
services. When "PsBeProcType" is set to
CORRM_SRNSR_PSBE_DSCR: If this switch is
turned on, UEs engaged in CS and PS BE combined
services can initiate static relocation. In this case, the
RNC releases the PS BE services and then originates the
static relocation procedure. If this switch is turned off,
such UEs cannot initiate static relocation. 4.
PERFENH_HSUPA_PO_THROU_MEAS_OPT_SW
ITCH: Whether to optimize the throughput
measurement control parameters when
PC_HSUPA_DATA_CH_PO_ADAPTIVE_ADJ_SW
ITCH of the "PcSwitch" parameter in the "SET
UCORRMALGOSWITCH" command is turned on.
When this switch is turned on, the E-DCH throughput
is measured every 2400 ms. The hysteresis for event 4A,
suspending time after event 4A is triggered, hysteresis
for event 4B, and suspending time after event 4B is
triggered last for one measurement period. When this

Timer after which the rate of PS BE services whose
uplink and downlink channel types are both DCHs will
be adjusted to the low-activity rate. When this switch is
turned off, the value is equal to MAX(BeE2FState-
TransTimer, BeD2FStateTransTimer). When this
switch is turned on, the value is equal to
BeD2FStateTransTimer. When a BE service rate
reduces to the DCCC rate threshold, the low-activity
rate, as substitution to a D2F transition, is used for the
BE service because state transition has not been enabled
or the UE processing CS services cannot transit to the
CELL_FACH state. The timer value and measurement
controls for low-activity rate adjustment use the
corresponding parameter values involved in the D2F
transitions. 7.
PERFENH_CS_TRIG_PS_P2D_ZERO_SWITCH:
Whether a PS BE service is limited to 0 kbit/s on the
DCH after a UE that has the PS BE service performs a
CELL_PCH/URA_PCH-to-CELL-DCH (P2D) state
transition triggered by a CS service setup. When this
switch is turned off, the PS BE service is limited to 8
kbit/s on the DCH after the UE performs a P2D state
transition. When this switch is turned on, the PS BE
service is limited to 0 kbit/s on the DCH after the UE
performs a P2D state transition. 8.
PERFENH_FACH_CONG_D2IDLE_SWITCH:
Whether the RNC releases all resources for a UE when
the FACH is congested. When this switch is turned on,
the RNC releases all resources for a UE if the following
conditions are met: The UE performs a CELL_DCH-to-
CELL_FACH state transition. The FACH is congested.
The UE is processing a non-real-time PS service that
has a traffic volume of 0 bytes. 9.
PERFENH_P2D_FAIL_RETRY_SWITCH: Whether
a UE is allowed to access an inter-frequency co-
coverage cell using DRD or channel fallback after P2D
state transition admission fails. When this switch is
turned off, the UE remains in the CELL_PCH state after
P2D state transition admission fails. 10.
PERFENH_PTT_IUR_D2F_SWITCH: Whether a
PTT user can perform a CELL_DCH-to-CELL_FACH
(D2F for short) state transition when Iur CCH is
disabled during a soft handover over the Iur interface.
Assume that this switch is turned on. If the DRNC cell
serves as the best cell, DSCR is triggered. If the SRNC
cell serves as the best cell, D2F is triggered. When this
switch is turned off, the original flow keeps unchanged.

Whether the low-activity rate algorithm can be used on
a UE that uses DCHs in only the uplink or downlink.
When this switch is turned on, the low-activity rate
algorithm can be used on the UE that uses DCHs in only
the uplink or downlink. When this switch is turned off,
the low-activity rate algorithm can be used on the UE
that uses DCHs in both the uplink and downlink. 12.
PERFENH_SRB_FAST_HRETRY_AFTER_DRD_S
WITCH: Whether the RNC triggers channel
reconfiguration for the SRBs to switch from the DCH
to an HSPA channel immediately when the type of a
channel for carrying SRBs during a DRD procedure is
limited. When this switch is turned off, channel
reconfiguration is not triggered and the SRBs are carried
on the DCH. When this switch is turned on, the RNC
triggers channel reconfiguration for the SRBs to switch
from the DCH to an HSPA channel immediately after
the DRD procedure. 13.
PERFENH_PTT_H2F_OPT_SWITCH: Whether the
traffic and throughput are measured during a state
transition from CELL_DCH to CELL_FACH (D2F for
short) when PTT services are carried on HSPA
channels. When this switch is turned off, the traffic and
throughput will not be measured during the D2F state
transition triggered by PTT services. When this switch
is turned on, the traffic and throughput will be measured
during the D2F state transition, which prevents the UE
from transiting to CELL_FACH if the UE has data to
transmit. In this case, if data transmission occurs during
the D2F state transition, the RNC stops the D2F state
transition. 14.
PERFENH_IUR_DB_TICK_OPT_SWITCH:
Whether the algorithm for optimizing the method of
saving the information about neighboring cells of a cell
under the DRNC during a handover over Iur is enabled
so that the CPU load on the SPUb board becomes
normal. When this switch is turned off, the algorithm is
disabled and the RNC saves the information about
neighboring cells in the original way. When this switch
is turned on, the algorithm is enabled. 15.
PERFENH_P2D_LIMIT_ON_DCH_LOWRATE_S
WITCH: Whether the PS BE service rate is limited to a
low level after the UE transits from CELL_PCH to
CELL_DCH (P2D for short). When this switch is turned
off, the channel for carrying the PS BE service and the
PS BE service rate are not limited after the UE transits

CELL_PCH to CELL_DCH. 16.
PERFENH_BASE_RES_BE_TTI_DELAY_SWITCH
: Whether the RNC starts a delay timer when the
algorithm for fairness-based handovers for
differentiated HSUPA TTI users is enabled. When this
switch is turned off, the delay timer does not start. When
this switch is turned on, the RNC starts the delay timer
after the algorithm for fairness-based handovers for
differentiated HSUPA TTI users us used to establish or
modify a throughput measurement. The handover from
HSUPPA 2 ms TTI users to 10 ms HSUPPA TTI users
cannot be triggered when the delay timer is running. 17.
PERFENH_BASE_ADM_CE_TTI2MS_LIMIT_SWI
TCH: Whether the RNC considers CE resource
congestion status of the target cell for admitting HSUPA
UEs when determining whether HSUPA services
support 2 ms TTI. When this switch is turned off, the
RNC does not consider CE resource congestion status
of the target cell when determining whether the HSUPA
services support 2 ms TTI. When this switch is turned
on, the RNC considers CE resource congestion status of
the target cell when determining whether the HSUPA
services support 2 ms TTI. If the CE resources are
congested, only HSUPA 10 ms TTI UEs are admitted.
18.
PERFENH_OLPC_SIRTAR_RESEND_SWITCH:
Whether the RNC sends the FP data frames that contain
the information element (IE) "Sir Target" to the NodeB
after service setup or reconfiguration succeeds and the
NodeB then adjusts inner loop power control based on
the configured target SIR value and actual target SIR
value. When this switch is turned off, the FP data frames
do not contain the IE "Sir Target". When this switch is
turned on, the RNC sends FP data frames that contain
the IE "Sir Target" to the NodeB for up to four times at
an interval of 1s. 19.
PERFENH_F2P_LIMIT_WITH_CS_IU_CON_SWIT
CH: Whether the RNC allows a UE to set up CS services
during a decision for state transition from CELL_FACH
to CELL_PCH or URA_PCH (F2P). When this switch
is turned off, the RNC does not allow the UE to set up
the CS service and continues performing the decision
for F2P state transition if a UE initiates a CS service
during a decision for F2P state transition. When this

a decision for F2P state transition, the RNC stops
performing the decision for F2P state transition and
allows the UE to set up the CS service. 20.
PERFENH_CS_PS_F2H_RATE_LIMIT_SWITCH:
Whether to limit the maximum data rate for HSDPA PS
services after a CS service setup triggers an F2D state
transition. When this switch is turned off, the maximum
data rate for HSDPA PS services is limited after a CS
service setup triggers an F2D state transition. When this
switch is turned on, the maximum data rate for HSDPA
PS services is unlimited after a CS service setup triggers
an F2D state transition. 21.
PERFENH_TTI_MC_UPDATE_OPT_SWITCH: TTI
reconfiguration optimization switch. When this switch
is turned off, the RNC updates the throughput
measurement control parameter for this algorithm after
the handover is complete and prohibits this algorithm
from triggering dynamic TTI shifts from 2 ms to 10 ms
in the following 5s. When this switch is turned on, the
RNC does not update the throughput measurement
control parameter for this algorithm if the parameter
does not change after a handover is complete. In this
case, the RNC triggers this algorithm upon receiving a
TTI measurement report. 22.
PERFENH_HRETRY_OPT_WITH_CM_SWITCH:
Whether to allow periodic access retry for UEs in
compressed mode to the (directed retry decision) DRD-
capable cell when candidate cells for periodic retry
include the current cell and neighboring DRD cells.
When this switch is turned off, periodic access retry for
UEs in compressed mode to the DRD-capable cell is not
allowed. When this switch is turned on, periodic access
retry for UEs in compressed mode to the DRD-capable
cell is allowed. 23.
PERFENH_UL_CHL_CHG_OLPC_OPT_SWITCH:
Whether to enable normal outer loop power control after
D2E reconfiguration in case of PS hard handover with
E2D channel fallback. When this switch is turned off,
normal outer loop power control is disabled after D2E
reconfiguration in case of PS hard handover with E2D
channel fallback. When this switch is turned on, normal
outer loop power control is enabled after D2E
channel fallback. 24.

SRNS relocation for CS+PS BE combined services.
When this switch is turned on and the relocation policies
for CS and PS services are different, the serving RNC
(SRNC) releases the PS services and then triggers a
combined hard handover and SRNS relocation for the
CS services. When this switch is turned off, the
combined hard handover and SRNS relocation is not
optimized. 25.
PERFENH_GSMOPGRP_TRANSTOSRNC_SWITC
H: Whether the drift RNC (DRNC) transfers
information about the intra circle roaming (ICR) license
of the cells under the DRNC, and the operator group and
the inter-RAT cell type for neighboring GSM cells to
the SRNC over proprietary information elements (IEs).
When this switch is turned on, the DRNC transfers
information about the ICR license of the cells under the
DRNC, and the operator group and the inter-RAT cell
type for neighboring GSM cells to the SRNC over the
private IEs in the Radio Link Setup Response or Radio
Link Addition Response message. When this switch is
turned off, the DRNC does not transfer the preceding
information. 26.
PERFENH_INTERRATHO_RETRY_SWITCH:
Whether the RNC initiates inter-RAT handovers
according to the coverage-based inter-RAT periodic
measurement report after inter-RAT handovers fail.
When this switch is turned on, the RNC still processes
the coverage-based inter-RAT periodic measurement
report reported by the UE and initiates inter-RAT
handovers after inter-RAT handovers fail. When this
switch is turned off, the RNC does not process the
coverage-based inter-RAT periodic measurement
report reported by the UE. 27.
PERFENH_ICR_GSMNCELL_FILTER_SWITCH:
When this switch is turned on, the RNC initiates an
inter-RAT handover towards the neighboring GSM cell
whose operator is the same as the UE's operator. This
increases the inter-RAT handover success rate. 28.
PERFENH_AMRC_DELAY_SWITCH: Whether to
delay adjusting the uplink voice service rate raised by
Adaptive Multi-Rate Control (AMRC). When this
switch is turned off, adjusting the uplink voice service
rate is not delayed. When this switch is turned on,
adjusting the uplink voice service rate is delayed. Before
a UE sends the first valid voice frame, the RNC does
not adjust the AMR rate for the UE. This avoids mute
voices on some UEs. 29.

ITCH: Whether to use the algorithm of UE location-
based HSUPA scheduling. When this switch is turned
on, the algorithm is used. When this switch is turned off,
the algorithm is not used. 2.
PERFENH_HRETRY_OPT_SWITCH: Whether the
algorithm of channel retry optimization takes effect.
When this switch is turned on, the algorithm takes effect
and channel retries are triggered in all scenarios where
the preconditions are met. However, turning on this
switch may increase the CPU usage. When this switch
is turned off, the algorithm does not take effect. 3.
PERFENH_IUR_CSPS_RELOC_OPT_SWITCH:
Static relocation policy for CS and PS BE combined
services. When "PsBeProcType" is set to
CORRM_SRNSR_PSBE_DSCR: If this switch is
turned on, UEs engaged in CS and PS BE combined
services can initiate static relocation. In this case, the
RNC releases the PS BE services and then originates the
static relocation procedure. If this switch is turned off,
such UEs cannot initiate static relocation. 4.
ITCH: Whether to optimize the throughput
measurement control parameters when
PC_HSUPA_DATA_CH_PO_ADAPTIVE_ADJ_SW
ITCH of the "PcSwitch" parameter in the "SET
UCORRMALGOSWITCH" command is turned on.
When this switch is turned on, the E-DCH throughput
is measured every 2400 ms. The hysteresis for event 4A,
suspending time after event 4A is triggered, hysteresis
for event 4B, and suspending time after event 4B is
triggered last for one measurement period. When this
switch is turned off, the E-DCH throughput is measured
every 300 ms. The hysteresis for event 4A, suspending
time after event 4A is triggered, hysteresis for event 4B,
and suspending time after event 4B is triggered last for
eight measurement periods. 5.
PERFENH_OLPC_BLER_COEF_ADJUSTOPT:
Switch for choosing the BLER coefficient adjustment
scheme for AMR services. When this switch is turned
off, the RNC adjusts the BLER coefficient based on load
reshuffling (LDR) or overload control (OLC) status.
When this switch is turned on, the RNC adjusts the
BLER coefficient based on the cell RTWP and actual
uplink service load reported by the NodeB. 6.

Timer after which the rate of PS BE services whose
uplink and downlink channel types are both DCHs will
be adjusted to the low-activity rate. When this switch is
turned off, the value is equal to MAX(BeE2FState-
TransTimer, BeD2FStateTransTimer). When this
switch is turned on, the value is equal to
BeD2FStateTransTimer. When a BE service rate
reduces to the DCCC rate threshold, the low-activity
rate, as substitution to a D2F transition, is used for the
BE service because state transition has not been enabled
or the UE processing CS services cannot transit to the
CELL_FACH state. The timer value and measurement
controls for low-activity rate adjustment use the
corresponding parameter values involved in the D2F
transitions. 7.
PERFENH_CS_TRIG_PS_P2D_ZERO_SWITCH:
Whether a PS BE service is limited to 0 kbit/s on the
DCH after a UE that has the PS BE service performs a
CELL_PCH/URA_PCH-to-CELL-DCH (P2D) state
transition triggered by a CS service setup. When this
switch is turned off, the PS BE service is limited to 8
kbit/s on the DCH after the UE performs a P2D state
transition. When this switch is turned on, the PS BE
service is limited to 0 kbit/s on the DCH after the UE
performs a P2D state transition. 8.
PERFENH_FACH_CONG_D2IDLE_SWITCH:
Whether the RNC releases all resources for a UE when
the FACH is congested. When this switch is turned on,
the RNC releases all resources for a UE if the following
conditions are met: The UE performs a CELL_DCH-to-
CELL_FACH state transition. The FACH is congested.
The UE is processing a non-real-time PS service that
has a traffic volume of 0 bytes. 9.
PERFENH_P2D_FAIL_RETRY_SWITCH: Whether
a UE is allowed to access an inter-frequency co-
coverage cell using DRD or channel fallback after P2D
state transition admission fails. When this switch is
turned off, the UE remains in the CELL_PCH state after
P2D state transition admission fails. 10.
PERFENH_PTT_IUR_D2F_SWITCH: Whether a
PTT user can perform a CELL_DCH-to-CELL_FACH
(D2F for short) state transition when Iur CCH is
disabled during a soft handover over the Iur interface.
Assume that this switch is turned on. If the DRNC cell
serves as the best cell, DSCR is triggered. If the SRNC
cell serves as the best cell, D2F is triggered. When this
switch is turned off, the original flow keeps unchanged.

Whether the low-activity rate algorithm can be used on
a UE that uses DCHs in only the uplink or downlink.
When this switch is turned on, the low-activity rate
algorithm can be used on the UE that uses DCHs in only
the uplink or downlink. When this switch is turned off,
the low-activity rate algorithm can be used on the UE
that uses DCHs in both the uplink and downlink. 12.
WITCH: Whether the RNC triggers channel
reconfiguration for the SRBs to switch from the DCH
to an HSPA channel immediately when the type of a
channel for carrying SRBs during a DRD procedure is
limited. When this switch is turned off, channel
reconfiguration is not triggered and the SRBs are carried
on the DCH. When this switch is turned on, the RNC
triggers channel reconfiguration for the SRBs to switch
from the DCH to an HSPA channel immediately after
the DRD procedure. 13.
PERFENH_PTT_H2F_OPT_SWITCH: Whether the
traffic and throughput are measured during a state
short) when PTT services are carried on HSPA
channels. When this switch is turned off, the traffic and
throughput will not be measured during the D2F state
transition triggered by PTT services. When this switch
is turned on, the traffic and throughput will be measured
during the D2F state transition, which prevents the UE
from transiting to CELL_FACH if the UE has data to
transmit. In this case, if data transmission occurs during
the D2F state transition, the RNC stops the D2F state
transition. 14.
PERFENH_IUR_DB_TICK_OPT_SWITCH:
Whether the algorithm for optimizing the method of
saving the information about neighboring cells of a cell
under the DRNC during a handover over Iur is enabled
so that the CPU load of the CP subsystem becomes
normal. When this switch is turned off, the algorithm is
disabled and the RNC saves the information about
neighboring cells in the original way. When this switch
is turned on, the algorithm is enabled. 15.
WITCH: Whether the PS BE service rate is limited to a
low level after the UE transits from CELL_PCH to
CELL_DCH (P2D for short). When this switch is turned
off, the channel for carrying the PS BE service and the
PS BE service rate are not limited after the UE transits

turned on, the PE BE service is limited to 8 kbit/s or 0
kbit/s on the DCH after the UE transits from
CELL_PCH to CELL_DCH. 16.
: Whether the RNC starts a delay timer when the
algorithm for fairness-based handovers for
differentiated HSUPA TTI users is enabled. When this
switch is turned off, the delay timer does not start. When
this switch is turned on, the RNC starts the delay timer
after the algorithm for fairness-based handovers for
differentiated HSUPA TTI users us used to establish or
modify a throughput measurement. The handover from
HSUPPA 2 ms TTI users to 10 ms HSUPPA TTI users
cannot be triggered when the delay timer is running. 17.
TCH: Whether the RNC considers CE resource
congestion status of the target cell for admitting HSUPA
UEs when determining whether HSUPA services
support 2 ms TTI. When this switch is turned off, the
RNC does not consider CE resource congestion status
of the target cell when determining whether the HSUPA
services support 2 ms TTI. When this switch is turned
on, the RNC considers CE resource congestion status of
the target cell when determining whether the HSUPA
services support 2 ms TTI. If the CE resources are
congested, only HSUPA 10 ms TTI UEs are admitted.
18.
PERFENH_OLPC_SIRTAR_RESEND_SWITCH:
Whether the RNC sends the FP data frames that contain
the information element (IE) "Sir Target" to the NodeB
after service setup or reconfiguration succeeds and the
NodeB then adjusts inner loop power control based on
the configured target SIR value and actual target SIR
value. When this switch is turned off, the FP data frames
do not contain the IE "Sir Target". When this switch is
turned on, the RNC sends FP data frames that contain
the IE "Sir Target" to the NodeB for up to four times at
an interval of 1s. 19.
CH: Whether the RNC allows a UE to set up CS services
during a decision for state transition from CELL_FACH
to CELL_PCH or URA_PCH (F2P). When this switch
is turned off, the RNC does not allow the UE to set up
the CS service and continues performing the decision
for F2P state transition if a UE initiates a CS service
during a decision for F2P state transition. When this

switch is turned on, if a UE initiates a CS service during
a decision for F2P state transition, the RNC stops
performing the decision for F2P state transition and
allows the UE to set up the CS service. 20.
PERFENH_CS_PS_F2H_RATE_LIMIT_SWITCH:
Whether to limit the maximum data rate for HSDPA PS
services after a CS service setup triggers an F2D state
transition. When this switch is turned off, the maximum
data rate for HSDPA PS services is limited after a CS
service setup triggers an F2D state transition. When this
switch is turned on, the maximum data rate for HSDPA
PS services is unlimited after a CS service setup triggers
an F2D state transition. 21.
PERFENH_TTI_MC_UPDATE_OPT_SWITCH: TTI
reconfiguration optimization switch. When this switch
is turned off, the RNC updates the throughput
measurement control parameter for this algorithm after
the handover is complete and prohibits this algorithm
from triggering dynamic TTI shifts from 2 ms to 10 ms
in the following 5s. When this switch is turned on, the
RNC does not update the throughput measurement
control parameter for this algorithm if the parameter
does not change after a handover is complete. In this
case, the RNC triggers this algorithm upon receiving a
TTI measurement report. 22.
PERFENH_HRETRY_OPT_WITH_CM_SWITCH:
Whether to allow periodic access retry for UEs in
compressed mode to the (directed retry decision) DRD-
capable cell when candidate cells for periodic retry
include the current cell and neighboring DRD cells.
When this switch is turned off, periodic access retry for
UEs in compressed mode to the DRD-capable cell is not
allowed. When this switch is turned on, periodic access
retry for UEs in compressed mode to the DRD-capable
cell is allowed. 23.
PERFENH_UL_CHL_CHG_OLPC_OPT_SWITCH:
Whether to enable normal outer loop power control after
D2E reconfiguration in case of PS hard handover with
E2D channel fallback. When this switch is turned off,
normal outer loop power control is disabled after D2E
channel fallback. When this switch is turned on, normal
outer loop power control is enabled after D2E
channel fallback. 24.

SRNS relocation for CS+PS BE combined services.
When this switch is turned on and the relocation policies
for CS and PS services are different, the serving RNC
(SRNC) releases the PS services and then triggers a
combined hard handover and SRNS relocation for the
CS services. When this switch is turned off, the
combined hard handover and SRNS relocation is not
optimized. 25.
H: Whether the drift RNC (DRNC) transfers
information about the intra circle roaming (ICR) license
of the cells under the DRNC, and the operator group and
the inter-RAT cell type for neighboring GSM cells to
the SRNC over proprietary information elements (IEs).
When this switch is turned on, the DRNC transfers
information about the ICR license of the cells under the
DRNC, and the operator group and the inter-RAT cell
type for neighboring GSM cells to the SRNC over the
private IEs in the Radio Link Setup Response or Radio
Link Addition Response message. When this switch is
turned off, the DRNC does not transfer the preceding
information. 26.
PERFENH_INTERRATHO_RETRY_SWITCH:
Whether the RNC initiates inter-RAT handovers
according to the coverage-based inter-RAT periodic
measurement report after inter-RAT handovers fail.
When this switch is turned on, the RNC still processes
the coverage-based inter-RAT periodic measurement
report reported by the UE and initiates inter-RAT
handovers after inter-RAT handovers fail. When this
switch is turned off, the RNC does not process the
coverage-based inter-RAT periodic measurement
report reported by the UE. 27.
PERFENH_ICR_GSMNCELL_FILTER_SWITCH:
When this switch is turned on, the RNC initiates an
inter-RAT handover towards the neighboring GSM cell
whose operator is the same as the UE's operator. This
increases the inter-RAT handover success rate. 28.
PERFENH_AMRC_DELAY_SWITCH: Whether to
delay adjusting the uplink voice service rate raised by
Adaptive Multi-Rate Control (AMRC). When this
switch is turned off, adjusting the uplink voice service
rate is not delayed. When this switch is turned on,
adjusting the uplink voice service rate is delayed. Before
a UE sends the first valid voice frame, the RNC does
not adjust the AMR rate for the UE. This avoids mute
voices on some UEs. 29.

algorithm for delaying adjusting the uplink rate using
AMRC can be enabled on all UEs. When this switch is
turned on, the scope of UEs is set by running the "ADD
UIMEITAC" command. In this case, the CN must
support CS IMEI query. 30.
PERFENH_SMLC_D2F_ALLOW_SWITCH:
Whether to allow state transition from CELL_FACH to
CELL_DCH and a location measurement control
message to be sent to the UE when the RNC receives a
RANAP Location Reporting Control message from the
CN and the DRA_PS_BE_STATE_TRANS_SWITCH
switch is turned off. When this switch is turned off, state
transition from CELL_FACH to CELL_DCH is not
allowed and the RNC does not send a location
measurement control message to the UE. When the
switch is turned on, state transition from CELL_FACH
to CELL_DCH is allowed and the RNC sends a location
measurement control message to the UE after state
transition is successful. 31.
H: Whether the RNC prohibits the PS RB
reconfiguration triggered by an uplink or downlink
event 4A measurement report if the status is congested
as indicated by Combined Service Power Resource
Congest State. When this switch is turned off, the RNC
allows the PS RB reconfiguration triggered by an event

cannot guarantee that all users can access the network
with the highest service bearer supported by UEs. This
switch controls whether the RNC allocates
corresponding channels for new users based on the cell
capability reported through the NodeB private interface.
When this switch is turned on, the RNC dynamically
selects an appropriate uplink service bearer and
allocates corresponding channels for new users to
maximize the system capacity based on the actual
NodeB processing specifications. When this switch is
turned off, the optimization process is disabled. 18.

RRC_CELLFACH_TRB_RESET_TO_F2D_SWITC
H (The CELL_FACH-to-CELL_DCH state (F2D)
transition switch by TRB reset) When the RNC receives
a TRB reset request from a UE in the CELL_FACH
state, the RNC cannot respond to the UE with a confirm
message if the FACH is congested. The
H parameter specifies whether a UE performs an F2D
transition if the number of TRB reset requests from the
UE to the RNC reaches a specified threshold. 1: This
switch is turned on. The UE moves from the
CELL_FACH state to the CELL_DCH state. 0: This
switch is turned off. The UE does not move from the

Transition from CELL_FACH to CELL_PCH or
URA_PCH) Whether the RNC queries the RLC state
before and after a UE moves from the CELL_FACH
state to the CELL_PCH or URA_PCH state due to event
4B. A UE in the CELL_FACH state can move to the
CELL_PCH or URA_PCH state even when there is
downlink data transmission for the UE. When this
occurs, data packets are suspended on the RNC side.
This switch is introduced to solve this problem. 1: This
switch is turned on. The RNC queries the RLC state
before a UE moves from the CELL_FACH state to the
CELL_PCH or URA_PCH state due to event 4B. If the
state query fails, the UE does not perform the state
transition. If the state query succeeds, the UE continues
with the state transition. The RNC queries the RLC state
again after the state transition is complete and before the
L2 link is deactivated. If there is SRB3, SRB4, or TRB
data to be transmitted to the UE on the RLC, the paging

CMP_RELOCIN_IUUPVER_NOTCHG_SWITCH:
When the switch is set to ON, the Iu user plane (UP)
version is not decreased if the Uu data rate set and the
Iu data rate set in the static relocation container are
different. Otherwise, the Iu UP version is decreased to
version 1. 2.
CMP_IUBR_DM_RTT_ALTERNATIVE_FMT_SWI
TCH: When the switch is set to ON, RTT dedicated
measurement adopts the extended cell mode. When the
switch is set to OFF, RTT dedicated measurement does
not adopt the extended cell mode. This parameter is used
to solve the problem that some NodeBs do not support
RTT dedicated measurement adopting the extended cell
mode. 3. CMP_IUR_CMCF_SWITCH: When the
switch is set to ON, compressed mode is started by using
a RADIO LINK RECONFIGURATION COMMIT
message. When the switch is set to OFF, compressed
mode is started by using a COMPRESSED MODE
COMMAND message. 4.
CMP_STTD_RL_ADD_SWITCH: When the switch is
set to ON, the transmit diversity mode information
element is always carried in the RADIO LINK SETUP
REQUEST message during radio link establishment if
a cell enabled with transmit diversity and another cell
disabled with transmit diversity exist under the same
NodeB. This parameter is used to solve the problem that
transmit diversity parameters are incorrectly configured
for softer handovers because the RADIO LINK
ADDITION REQUEST message does not carry the
transmit diversity mode. 5.
CMP_STTD_ASU_SWITCH: When a UE is soft-
handed over from a cell enabled with transmit diversity
to a cell disabled with transmit diversity, the UE may
return active set update failure. If the switch is set to
ON, the RNC resends the active set update message to
the UE after an active set update failure. If the switch is
set to OFF, the RNC does not resend an active set update
message after an active set update failure. 6.
CMP_RAB_DRD_ROLLBACK_PUNISH_SWITCH:
When the switch is set to OFF, a penalty is imposed on
a failed directed retry due to any failures on the Uu
interface during the whole call. When the switch is set
to ON, no penalty is imposed on a failed directed retry
after best cell changed. By default, this switch is set to
OFF. 7. CMP_WBAMR_SUBFLOW_SWITCH:

service substreams is configured according to the
number of substreams specified in the RAB
ASSIGNMENT REQUEST message. When the switch
is set to OFF, the number of WB AMR service
substreams is 3. This switch is introduced to comply
with the Change Request (CR) specified in the related
protocol, that is, three substreams need to be established
for a WB AMR service. The switch
CMP_WBAMR_SUBFLOW_SWITCH in this version
supports configuration synchronization and delivery,
but the RNC does not use this switch any longer. Future
versions do not support this switch. Therefore, it is
recommended that users avoid using this switch. 8.
CMP_IUR_CELLCAP_BITMAP_TRANSFORM_S
WITCH: The switch is used to solve the problem that
different vendors' RNCs interpret the cell capability
bitmap differently on the Iur interface. When the switch
is set to ON, the RNC interprets the cell capability
bitmap in a sequence opposite to that specified by the
related protocol. When the switch is set to OFF, the
RNC interprets the cell capability bitmap in the
sequence specified by the related protocol. 9.
CMP_MOCN_PLMN_SEL_SWITCH: When the
switch is set to ON, if the UE supports the MOCN
feature, the SRNC preferentially uses the PLMN of the
UE's homing operator in the RELOCATION
REQUIRED message, and the TRNC preferentially
uses the PLMN of the UE's homing operator in the
LOCATION REPORT message and the DIRECT
TRANSFER message during relocation; if the UE does
not support the MOCN feature, the SRNC and the
TRNC preferentially use the common operator's PLMN
in these above messages. When the switch is set to OFF,
the SRNC preferentially uses the PLMN of the UE's
homing operator in the RELOCATION REQUIRED
message, and the TRNC preferentially uses the PLMN
of the UE's homing operator in the LOCATION
REPORT message, but the TRNC preferentially uses
the common operator's PLMN in the DIRECT
TRANSFER message during relocation. 10.
CMP_LOSSLESS_RELOC_RLCPDUSIZECHG_SW
ITCH: When the switch is set to ON, the RNC sets the
"Support for lossless SRNS relocation or for lossless DL
RLC PDU size change" IE transmitted on the Uu
interface to TRUE only if the UE supports both lossless
SRNS relocation and downlink RLC PDU size change.

CMP_CS_FIXED_RATE_WHEN_PS_EXIST_SWIT
CH: When the switch is set to ON, the RNC sets the
uplink mode of an AMR service to maximum uplink
rate, 0, and SID if the UE has an established PS service.
In this case, the AMRC algorithm is not considered. 12.
CMP_SRB_H_AMR_DRD_HHO_SWITCH:
Whether DRD can be performed during AMR service
establishment if signaling is carried over HSPA. When
this switch is turned on, DRD cannot be performed
during AMR service establishment when signaling is
carried over HSPA. When this switch is turned off, DRD
can be performed during AMR service establishment
when signaling is carried over HSPA. 13.
CMP_UU_AMR_DRD_HHO_COMPAT_ENH_SWI
TCH: Whether to enable the enhanced AMR anti-static
function. When this switch is turned on and the DRD
procedure is triggered, the RNC initiates an inter-
frequency blind handover to move a UE to the target cell
and then processes an AMR service in the target cell for
the UE if one of following conditions is met: SRBs are
carried over HSPA channels and the UE is processing
an AMR service only. The US initiates an AMR service
when a PS service is still in progress. When this switch
is turned off and the DRD procedure is triggered, the
RNC initiates an inter-frequency blind handover and
processes an AMR service in the target cell for the UE
at the same time if one of the preceding conditions is
also met. 14.
CMP_SINGLE_PTT_USE_DL_ENL2_SWITCH:
Whether to enable the DL Layer 2 Improvement feature
for E_PCH-incapable UEs processing only PTT
services. When this switch is turned on, the DL Layer 2
Improvement feature is enabled for E_PCH-incapable
UEs processing only PTT services. When this switch is
turned off, the DL Layer 2 Improvement feature is not
enabled for E_PCH-incapable UEs processing only
PTT services. 15.
CMP_F2D_RLC_ONESIDE_REBUILD_SWITCH:
Whether the RLC entity can be re-established in only
the uplink or downlink during the state transition from
CELL_FACH to CELL_DCH (F2D for short). When
this switch is turned off, the RLC entity must be re-
established in both uplink and downlink during the F2D

see 3GPP TS 25.331. 16.
CMP_DRD_SRBOVERH_SWITCH: Whether
signaling radio bearers (SRBs) can be switched over
from FACH or DCHs to HSPA channels during directed
retry. When this switch is turned off, SRBs can be
switched over from FACH or DCHs to HSPA channels
during directed retry. When this switch is turned on,
SRBs cannot be switched over from FACH or DCHs to
HSPA channels during directed retry. Note: This is a
general switch for prohibiting SRBs from being
during directed retry. To enable the prohibition to take
effect during RB setups, turn on the
CMP_RBSETUP_DRD_SRBOVERH_SWITCH
under the "CmpSwitch3" parameter. To enable the
prohibition to take effect during RB reconfiguration,
turn on the
CMP_RBCFG_DRD_SRBOVERH_SWITCH under
the "CmpSwitch3" parameter. 17.
CMP_AMRC_FIXED_INITRATE_SWITCH:
Whether the RNC considers the cell congestion state
when determining the initial AMR rate mode during an
AMR service setup and whether to use the same rate
mode for the uplink and downlink during RB
reconfigurations for WB-AMR services in the case of
code congestion. When this switch is set to off, the RNC
considers the cell congestion state during an AMR
service setup. When AMRC is enabled, the guaranteed
bit rate (GBR) is used for uplink admission if the uplink
is congested. If the downlink is congested, the GBRs are
used for both uplink and downlink admission. During
RB reconfigurations for WB-AMR services, the uplink
and downlink can use different rate modes. However,
the reconfigured uplink rate must be smaller than or
equal to the reconfigured downlink rate. When this
switch is set to on, the RNC does not consider the cell
congestion state and the maximum bit rates (MBRs) are
used for uplink and downlink admission during an AMR
service setup. During RB reconfigurations for WB-
AMR services, the RNC uses the same rate mode for the
uplink and downlink. 18.

neighboring cell for blind handovers cannot serve as the
target neighboring cell for inter-frequency blind
handovers if the difference between the downlink load
margins of the neighboring cell and the current cell is
less than the value of the "LdbDRDOffsetDCH" or
"LdbDRDOffsetHSDPA" parameter. When this switch
is turned on, the RNC does not filter out any neighboring
cell for blind handovers. 19.
CMP_AMR_A_SUBFLOW_ZERO_BLOCK_SWIT
CH: Uplink 0 kbit/s transport format of AMR service
subflow A, expressed in TbNum * TbSize. When this
switch is turned off, the format is 1*0. When this switch
is turned on, the format is 0*TbSize. 20.
CMP_IUR_MULTI_RL_ADD_RETRY_SWITCH:
Whether to enable the compatibility algorithm when
multiple RLs are added to the same DRNC. When this
switch is turned off, the RNC stops attempting to re-
establish the RL if an RL fails to be added with the
failure cause of "RadioNetwork:unspecified (14)".
When this switch is turned on, the RNC attempts to re-
establish the RL only once if an RL fails to be added
with the failure cause of "RadioNetwork:unspecified

CMP_MBDR_CALL_TYPE_OTHER_AS_AMR_S
WITCH: Whether a conversational service of a UE
complying with 3GPP Release 6 and later are allowed
for inter-RAT measurement-based directed retry
(MBDR) if CallType of the conversational service is
Other. 22.
CMP_SRNSR_WAMR_MODE_0_RESTORE_SWIT
CH: Whether the 0 kbit/s transport format is added on
the Iu interface during an incoming static relocation of
a WB-AMR speech service. When this switch is turned
off, the 0 kbit/s transport format is added on the Iu
interface if the Uu interface has the 0 kbit/s transport
format. When this switch is turned on, the 0 kbit/s
transport format is added on the Iu interface if both the
Uu interface and the RAB parameters in the
RELOCATION REQUEST message have the 0 kbit/s
transport format. 23.

Meaning: 1.
When the switch is set to ON, the Iu user plane (UP)
version is not decreased if the Uu data rate set and the
Iu data rate set in the static relocation container are
different. Otherwise, the Iu UP version is decreased to
version 1. 2.
TCH: When the switch is set to ON, RTT dedicated
measurement adopts the extended cell mode. When the
switch is set to OFF, RTT dedicated measurement does
not adopt the extended cell mode. This parameter is used
to solve the problem that some NodeBs do not support
RTT dedicated measurement adopting the extended cell
mode. 3. CMP_IUR_CMCF_SWITCH: When the
switch is set to ON, compressed mode is started by using
a RADIO LINK RECONFIGURATION COMMIT
message. When the switch is set to OFF, compressed
mode is started by using a COMPRESSED MODE
COMMAND message. 4.
CMP_STTD_RL_ADD_SWITCH: When the switch is
set to ON, the transmit diversity mode information
element is always carried in the RADIO LINK SETUP
REQUEST message during radio link establishment if
a cell enabled with transmit diversity and another cell
disabled with transmit diversity exist under the same
NodeB. This parameter is used to solve the problem that
transmit diversity parameters are incorrectly configured
for softer handovers because the RADIO LINK
ADDITION REQUEST message does not carry the
transmit diversity mode. 5.
CMP_STTD_ASU_SWITCH: When a UE is soft-
handed over from a cell enabled with transmit diversity
to a cell disabled with transmit diversity, the UE may
return active set update failure. If the switch is set to
ON, the RNC resends the active set update message to
the UE after an active set update failure. If the switch is
set to OFF, the RNC does not resend an active set update
message after an active set update failure. 6.
CMP_RAB_DRD_ROLLBACK_PUNISH_SWITCH:
When the switch is set to OFF, a penalty is imposed on
a failed directed retry due to any failures on the Uu
interface during the whole call. When the switch is set
to ON, no penalty is imposed on a failed directed retry
after best cell changed. By default, this switch is set to
OFF. 7. CMP_WBAMR_SUBFLOW_SWITCH:

service substreams is configured according to the
number of substreams specified in the RAB
ASSIGNMENT REQUEST message. When the switch
is set to OFF, the number of WB AMR service
substreams is 3. This switch is introduced to comply
with the Change Request (CR) specified in the related
protocol, that is, three substreams need to be established
for a WB AMR service. The switch
CMP_WBAMR_SUBFLOW_SWITCH in this version
supports configuration synchronization and delivery,
but the RNC does not use this switch any longer. Future
versions do not support this switch. Therefore, it is
recommended that users avoid using this switch. 8.
WITCH: The switch is used to solve the problem that
different vendors' RNCs interpret the cell capability
bitmap differently on the Iur interface. When the switch
is set to ON, the RNC interprets the cell capability
bitmap in a sequence opposite to that specified by the
related protocol. When the switch is set to OFF, the
RNC interprets the cell capability bitmap in the
sequence specified by the related protocol. 9.
CMP_MOCN_PLMN_SEL_SWITCH: When the
switch is set to ON, if the UE supports the MOCN
feature, the SRNC preferentially uses the PLMN of the
UE's homing operator in the RELOCATION
REQUIRED message, and the TRNC preferentially
uses the PLMN of the UE's homing operator in the
LOCATION REPORT message and the DIRECT
TRANSFER message during relocation; if the UE does
not support the MOCN feature, the SRNC and the
TRNC preferentially use the common operator's PLMN
in these above messages. When the switch is set to OFF,
the SRNC preferentially uses the PLMN of the UE's
homing operator in the RELOCATION REQUIRED
message, and the TRNC preferentially uses the PLMN
of the UE's homing operator in the LOCATION
REPORT message, but the TRNC preferentially uses
the common operator's PLMN in the DIRECT
TRANSFER message during relocation. 10.
ITCH: When the switch is set to ON, the RNC sets the
interface to TRUE only if the UE supports both lossless
SRNS relocation and downlink RLC PDU size change.
When the switch is set to OFF, the RNC sets the

relocation or downlink RLC PDU size change. 11.
CH: When the switch is set to ON, the RNC sets the
uplink mode of an AMR service to maximum uplink
rate, 0, and SID if the UE has an established PS service.
In this case, the AMRC algorithm is not considered. 12.
CMP_SRB_H_AMR_DRD_HHO_SWITCH:
Whether DRD can be performed during AMR service
establishment if signaling is carried over HSPA. When
this switch is turned on, DRD cannot be performed
during AMR service establishment when signaling is
carried over HSPA. When this switch is turned off, DRD
can be performed during AMR service establishment
when signaling is carried over HSPA. 13.
TCH: Whether to enable the enhanced AMR anti-static
function. When this switch is turned on and the DRD
procedure is triggered, the RNC initiates an inter-
frequency blind handover to move a UE to the target cell
and then processes an AMR service in the target cell for
the UE if one of following conditions is met: SRBs are
carried over HSPA channels and the UE is processing
an AMR service only. The US initiates an AMR service
when a PS service is still in progress. When this switch
is turned off and the DRD procedure is triggered, the
RNC initiates an inter-frequency blind handover and
processes an AMR service in the target cell for the UE
at the same time if one of the preceding conditions is
also met. 14.
CMP_SINGLE_PTT_USE_DL_ENL2_SWITCH:
Whether to enable the DL Layer 2 Improvement feature
for E_PCH-incapable UEs processing only PTT
services. When this switch is turned on, the DL Layer 2
Improvement feature is enabled for E_PCH-incapable
UEs processing only PTT services. When this switch is
turned off, the DL Layer 2 Improvement feature is not
enabled for E_PCH-incapable UEs processing only
PTT services. 15.
CMP_F2D_RLC_ONESIDE_REBUILD_SWITCH:
Whether the RLC entity can be re-established in only
the uplink or downlink during the state transition from
CELL_FACH to CELL_DCH (F2D for short). When
this switch is turned off, the RLC entity must be re-
established in both uplink and downlink during the F2D

see 3GPP TS 25.331. 16.
CMP_DRD_SRBOVERH_SWITCH: Whether
signaling radio bearers (SRBs) can be switched over
from FACH or DCHs to HSPA channels during directed
retry. When this switch is turned off, SRBs can be
during directed retry. When this switch is turned on,
SRBs cannot be switched over from FACH or DCHs to
HSPA channels during directed retry. Note: This is a
general switch for prohibiting SRBs from being
during directed retry. To enable the prohibition to take
effect during RB setups, turn on the
CMP_RBSETUP_DRD_SRBOVERH_SWITCH
under the "CmpSwitch3" parameter. To enable the
prohibition to take effect during RB reconfiguration,
turn on the
CMP_RBCFG_DRD_SRBOVERH_SWITCH under
the "CmpSwitch3" parameter. 17.
CMP_AMRC_FIXED_INITRATE_SWITCH:
Whether the RNC considers the cell congestion state
when determining the initial AMR rate mode during an
AMR service setup and whether to use the same rate
mode for the uplink and downlink during RB
reconfigurations for WB-AMR services in the case of
code congestion. When this switch is set to off, the RNC
considers the cell congestion state during an AMR
service setup. When AMRC is enabled, the guaranteed
bit rate (GBR) is used for uplink admission if the uplink
is congested. If the downlink is congested, the GBRs are
used for both uplink and downlink admission. During
RB reconfigurations for WB-AMR services, the uplink
and downlink can use different rate modes. However,
the reconfigured uplink rate must be smaller than or
equal to the reconfigured downlink rate. When this
switch is set to on, the RNC does not consider the cell
congestion state and the maximum bit rates (MBRs) are
used for uplink and downlink admission during an AMR
service setup. During RB reconfigurations for WB-
AMR services, the RNC uses the same rate mode for the
uplink and downlink. 18.

neighboring cell for blind handovers cannot serve as the
target neighboring cell for inter-frequency blind
handovers if the difference between the downlink load
margins of the neighboring cell and the current cell is
less than the value of the "LdbDRDOffsetDCH" or
"LdbDRDOffsetHSDPA" parameter. When this switch
is turned on, the RNC does not filter out any neighboring
cell for blind handovers. 19.
CH: Uplink 0 kbit/s transport format of AMR service
subflow A, expressed in TbNum * TbSize. When this
switch is turned off, the format is 1*0. When this switch
is turned on, the format is 0*TbSize. 20.
CMP_IUR_MULTI_RL_ADD_RETRY_SWITCH:
Whether to enable the compatibility algorithm when
multiple RLs are added to the same DRNC. When this
switch is turned off, the RNC stops attempting to re-
establish the RL if an RL fails to be added with the
failure cause of "RadioNetwork:unspecified (14)".
When this switch is turned on, the RNC attempts to re-
establish the RL only once if an RL fails to be added
with the failure cause of "RadioNetwork:unspecified
(14)". 21.
WITCH: Whether a conversational service of a UE
complying with 3GPP Release 6 and later are allowed
for inter-RAT measurement-based directed retry
(MBDR) if CallType of the conversational service is
Other. 22.
CH: Whether the 0 kbit/s transport format is added on
the Iu interface during an incoming static relocation of
a WB-AMR speech service. When this switch is turned
off, the 0 kbit/s transport format is added on the Iu
interface if the Uu interface has the 0 kbit/s transport
format. When this switch is turned on, the 0 kbit/s
transport format is added on the Iu interface if both the
Uu interface and the RAB parameters in the
RELOCATION REQUEST message have the 0 kbit/s
transport format. 23.

When this switch is turned off, the frequency band of
the inter-RAT neighboring cell is set as required. 24.
H: Whether the intra-frequency measurement reports of
UEs must contain synchronization information about
the cells in the active set. When this switch is turned off,
the intra-frequency measurement reports of UEs must

at a rate of 6.8 kbit/s if all the downlink traffic is on the
HSDPA channel. 8.
MAP_SRB_ON_DCH_OR_FACH_CS_RRC_SWIT
CH: When this switch is turned on, the SRB of a CS
RRC connection cannot be established on HSPA
channels. The RNC determines whether an RRC
connection request is for a CS service based on the RRC
connection setup cause and the value of Domain
Indicator. For a UE of a version earlier than Release 6,
the RRC connection setup cause of CS services is
Originating Conversational Call or Terminating
Conversational Call. For a UE of Release 6 or a later
version, the value of Domain Indicator must be CS and
the RRC connection setup cause must be Originating
Conversational Call or Terminating Conversational
Call for a CS service. 9.

MAP_CSPS_TTI_2MS_LIMIT_SWITCH: Whether
CS and PS combined services can use HSUPA 2ms
transmission time interval (TTI). When this switch is
turned on, CS and PS combined services cannot use
HSUPA 2ms TTI, which reduces CS call drops caused
by TTI switching. When this switch is turned off, CS
and PS combined services can use HSUPA 2ms TTI.
10. MAP_CSPS_PS_UL_USE_DCH_SWITCH:
Whether uplink PS services of CS and PS combined
services are carried on DCHs. When this switch is
turned off, the RNC determines the channel for carrying
uplink services of CS and PS combined services. When
this switch is turned on and CS and PS combined
services existing, the uplink PS services must be carried
on DCHs. 11.
MAP_CSPS_PS_DL_USE_DCH_SWITCH: Whether
downlink PS services of CS and PS combined services
are carried on DCHs. When this switch is turned off, the
RNC determines the channel carrying the downlink PS
services of the CS and PS combined services. When this
switch is turned on and CS and PS combined services
existing, the downlink PS services must be carried on
DCHs. 12. MAP_CSPS_MC_LIMIT_SWITCH:
Whether to allow UEs to perform CS+PS combined
services using MC HSPA.When this switch is turned on,
UEs are not allowed to perform CS+PS combined
services using MC HSPA (MC stands for multi-carrier.)
This prevents call drops that are caused by frequent
reconfigurations in areas bordered by MC and non-MC
cells.When this switch is turned off, UEs are allowed to
perform CS+PS combined services using MC HSPA.
13. MAP_CSPS_RL_RESET_0K_LIMIT_SWITCH:
Whether to allocate a 0 kbit/s DCH to the PS service of
CS+PS combined services during link reestablishment
When this switch is turned on, a 0 kbit/s DCH is
allocated to the PS service of CS+PS combined services
during link reestablishment and the data rate of the CS
service remains unchanged. This prevents call drops in
case of poor coverage.
