2 Overview of ATM Transport
Huawei radio access network (RAN) provides ATM-based Iub/Iu(Iu-CS and Iu-PS)/Iur interfaces and
ATM TRM, such as admission control based on AAL2 path bandwidth; transmission resource mapping
based on ATM QoS classes, and Iub overbooking.

ATM Transport 3 Protocol Stacks
3-1
3 Protocol Stacks
3.1 Iub Over ATM
3.1.1 Protocol Stack
Figure 3-1 shows the protocol stack for the ATM-based Iub interface.
Figure 3-1 Protocol stack for the ATM-based Iub interface
The transport network layer of the Iub interface consists of the transport network layer user plane (area
A), transport network layer control plane (area B), and transport network layer user plane (area C).
 Areas A, B, and C share the physical layer and ATM layer. Therefore, all links in the three areas can be
carried on common physical links.
 Links in areas A and B are carried on SAAL links. Based on the type of carried information, the upper
layer of area A is classified into the NodeB Control Port (NCP) and the Communication Control Port
(CCP). Only Q.AAL2 links are carried in area B.
 In area C, the user plane data is carried on AAL2 paths. The bearer at the lower layer is the ATM PVC.
Under the control of Q.AAL2, AAL2 connections can be dynamically set up or released for upper-layer
services. Therefore, each AAL2 path must have its corresponding controlling Q.AAL2.
3.1.2 Links on the Iub Interface
The links on the ATM-based Iub interface are of three types: SAAL link of User-Network Interface (UNI)
type, AAL2 path, and IPoA PVC. The SAAL link of UNI type is used to carry NCP, CCP, and ALCAP, as
shown in Figure 3-2.

3.1.3 OM IPoA Data Configuration on the Iub Interface
On the ATM-based Iub interface, the IPoA PVC functions as the Operation and Maintenance (OM)
channel.

The RINT shown in Figure 3-3 refers to ATM interface boards UOIa/UOIc, AOUa/AOUc, and AEUa.
Network Segments
Iub OM channel travels through the following network segments before reaching the NodeB:
 The 80.168.3.0 segment (with network mask of 255.0.0.0) between the OM board and the ATM
interface board. This network segment is set before delivery of the BSC6900.
 The 12.13.1.0 segment (with network mask of 255.255.255.0) between the ATM interface board and
the NodeBs. When setting this network segment, you need to take field conditions into consideration.
3.2 Iu-CS over ATM
Figure 3-4 shows the protocol stack for the Iu-CS interface.
Figure 3-4 Protocol stack for the ATM-based Iu-CS interface
The transport network layer of the Iu-CS interface consists of the following areas:
 Transport network layer user plane (area A)
 Transport network layer control plane (area B)
 Transport network layer user plane (area C)
Areas A, B, and C share the physical layer and ATM layer. Therefore, all links in the three areas can be

The MSC in an R99 network implements the functions in areas A, B, and C of the protocol stack. The
MSC server and MGW in an R4/R5/R6/R7/R8 network implement their functions as follows:
 The MSC server implements the functions in area A.
 The MGW implements the functions in areas B and C.
3.2.2 Links on the Iu-CS Interface
The Iu-CS links on the CN side are of two types: MTP3 link and AAL2 path. Figure 3-5 shows the links
on the ATM-based Iu-CS interface.
Figure 3-5 Links on the Iu-CS Interface
The RINT shown in Figure 3-5 refers to ATM interface boards of the BSC6900. The UOIa/UOIc board is recommended
when ATM transport is applied to the Iu-CS interface.
3.2.3 Differences of the Iu-CS Interface Between R99 and
R4/R5/R6/R7/R8
In the 3GPP R99, the MSC connects to the BSC6900 as one entity. In the 3GPP R4/R5/R6/R7/R8, the
MSC connects to the BSC6900 after being split into two entities, namely, MSC server and MGW.
Iu-CS Interface Defined in the 3GPP R4/R5/R6/R7/R8
Figure 3-6 shows the Iu-CS interface in the 3GPP R4/R5/R6/R7/R8.

WCDMA RAN
3-5
Figure 3-6 Iu-CS interface in the 3GPP R4/R5/R6/R7/R8
The network may require multiple MGWs depending on the traffic volume.
In practice, the MSC server is often not directly connected to the BSC6900. Data is forwarded between
the MSC server and the BSC6900 through the routes configured on the MGW. Figure 3-7 shows an
example of the network structure on the Iu-CS interface in the 3GPP R4/R5/R6/R7/R8.
Figure 3-7 Example of the network structure on the Iu-CS interface in the 3GPP R4/R5/R6/R7/R8
Data Configuration on the BSC6900
In the 3GPP R99, the BSC6900 needs to be configured with only one type of Iu-CS signaling point, that
is, the MSC.
In the 3GPP R4/R5/R6/R7/R8, the BSC6900 needs to be configured with the following two types of
Iu-CS signaling point:
 MSC server (also called Iu-CS RANAP signaling point)
 MGW (also called Iu-CS ALCAP signaling point)

Figure 3-8 Protocol stack for the ATM-based Iu-PS interface
The transport network layer of the Iu-PS interface consists of the transport network layer user plane
(area A) and the transport network layer user plane (area C).
Areas A and C share the physical layer and ATM layer. Therefore, all links in the two areas can be

3.3.2 Links on the Iu-PS Interface
The Iu-PS links on the CN side are of two types: MTP3 link and IPoA PVC. Figure 3-9 shows the links on
the ATM-based Iu-PS interface.

If the IP address of the interface board carrying the IPoA
data and the IP address of the peer SGSN are located on
different subnets, routes to the destination IP address
need to be configured at the BSC6900. DSTIP is the IP
address of the SGSN, and NEXTHOP is the IP address of
the gateway on the SGSN side.
On the Iu-PS interface, the SGSN must be configured with routes to the network segment to which the IP address of the
BSC6900 interface board belongs. The next hop is the gateway on the BSC6900 side. Otherwise, PS services cannot be
provided.

 Transport network layer user plane (area C)
3.4.2 Links on the Iur Interface
The Iur links are of two types: MTP3 link and AAL2 path. Figure 3-12 shows the links on the ATM-based
Iur interface.

The RINT shown in Figure 3-12 refers to ATM interface boards UOIa/UOIc.
3.4.3 Configuration Principles for Static Relocation Routes over Iur
The IP routes on the Iur interface are used to forward the PS data during Serving Radio Network
Subsystem (SRNS) relocation. During the SRNS relocation, the PS data is transferred from the local
BSC6900 to the SGSN and then to the neighboring BSC6900. Therefore, the prerequisites for
configuring IP routes on the Iur interface are that the IP paths between the local BSC6900 and the SGSN,
between the neighboring BSC6900 and the SGSN, and between the serving BSC6900 and the drift
BSC6900 are configured.
Figure 3-13 shows the configuration of IP routes on the Iur interface. The IP routes configured in multiple
subsystems are similar.

The RINT shown in Figure 3-13 refers to Iu-PS IP interface boards GOUa/GOUc, FG2a/FG2c, and UOIa(UOIa_IP).
3.5 ATM Transport Modes
ATM transport has three modes: UNI, fractional, and IMA.
3.5.1 UNI Mode
Principles of UNI Mode
The UNI mode is a transport mode at the Transmission Convergence (TC) sublayer of the physical layer.
In UNI mode, an ATM cell is directly carried on an E1/T1 frame and the bits of the ATM cell are
sequentially mapped to the valid timeslots on the E1/T1 frame. Figure 3-14 shows the mapping between
the ATM cell and the E1 timeslots in UNI mode. The 53 bytes of the ATM cell are sequentially carried on
E1 timeslots. Each E1 frame provides 31 timeslots (with slot 0 unavailable) for carrying the ATM cell.

WCDMA RAN
3-12
Figure 3-14 Mapping between the ATM cell and the E1 timeslots in UNI mode
The UNI mode has the characteristics of scrambling, line coding, 16-timeslot enabling, and clock mode.
The related parameters are as follows:
 Scrambling switch: specifies whether to enable scrambling.
 Line coding method: specifies the line coding method.
 16-timeslot switch: specifies whether to use timeslot 16 or not.
The settings of scrambling switch, line coding method, and 16-timeslot switch at both ends of E1/T1
must be identical.
The parameters corresponding to UNI mode are shown in Table 3-3.
Table 3-3 Parameters correspond to UNI mode
NE Scrambling Switch Line Coding Method 16-Timeslot Switch
RNC SCRAMBLESW PTCODE TS16ENABLE
NodeB SCRAM LNCODE TS16
Clock Mode
There are two clock modes on the RNC side:
 Common Transmit Clock (CTC): In CTC clock mode, all links in an IMA group share one clock source.
The clock source may be extracted from the same external clock or from a link.
 Independent Transmit Clock (ITC): In ITC mode, the clocks used by the links within an IMA group are
derived from at least two clock sources. The loopback clock mode is a special case of the ITC mode.
The clock mode on the RNC is not configurable, and the default clock mode on the RNC side is CTC.

WCDMA RAN
3-13
The clock mode on the NodeB side is specified by the parameter CLKM(UNI mode/fractional
mode)/CLKM(IMA mode). The clock mode settings at both ends of E1/T1 must be identical.
Line Coding Method
There are four line coding method:
 HDB3 (for E1 port)
 AMI (for E1/T1 port)
 AMI_ZCS (for E1/T1 port)
 B8ZS (for T1 port)
The coding methods of E1 port are HDB3 and AMI, and the HDB3 is recommended. HDB3 represents
high-density bipolar code. It is not easy to be interfered, and the transmission distance is about several
kilometers.
The coding methods of T1 port are B8ZS and AMI, and B8ZS is recommended. It helps prevent clock
signals from being lost, while AMI cannot perform this function.
3.5.2 Fractional Mode
Fractional mode (WRFD-050302 Fractional ATM Function on Iub Interface) is applicable to the
Transmission Convergence (TC) sublayer of the physical layer. This section describes the principles and
functions of fractional ATM, introduces the two implementation modes (that is, fractional IMA and
fractional ATM), and provides the principles for configuring fractional IMA links and fractional ATM links.
Principles of Fractional ATM
In the case of fractional ATM, multiple timeslots out of the 32 timeslots on an E1 (or 24 timeslots on a T1)
are used to transmit an ATM cell. At the transmission end, an ATM cell is mapped to multiple timeslots
among the 31 timeslots on an E1 (or 24 timeslots on a T1). At the reception end, the ATM cell is restored
from the associated timeslots on the E1/T1. Figure 3-15 shows the fractional ATM mode. An E1 frame
has timeslots numbered from 0 to 31. All the timeslots except timeslot 0 are available for service data
transmission. A T1 frame has timeslots numbered from 1 to 24. All the timeslots are available for service
data transmission. The timeslots to which the ATM cell is not mapped can transmit other data.
Figure 3-15 Fractional ATM mode
If multiple E1/T1 trunks exist between the transmission end and the reception end and work in IMA mode,
such an IMA mode is called fractional IMA. In fractional IMA mode, an IMA group contains multiple
fractional ATM links.
The fractional ATM mode has the characteristics of scrambling, line coding, and clock mode. For details
about clock mode, see Clock Mode. The related parameters are as follows:

WCDMA RAN
3-14
 E1/T1 timeslot: specifies the timeslot used to transmit the ATM cell.
The setting of scrambling switch, line coding method, and E1/T1 timeslot at both ends of E1/T1 must be
identical.
The parameters corresponding to fractional mode are shown in Table 3-4.
Table 3-4 Parameters correspond to fractional mode

RNC SCRAMBLESW PTCODE TSBITMAP
NodeB SCRAM LNCODE TSN
Function of Fractional ATM
After the fractional ATM function is enabled, the ATM cells of a 3G network can be transmitted over an
existing 2G network, as shown in Figure 3-16.
Figure 3-16 Fractional ATM function
Two Modes of the Fractional ATM Function
There are two implementation modes of the fractional ATM function on the Iub interface:
 Fractional ATM
In fractional ATM mode, multiple idle timeslots can be used for transmission.
 Fractional IMA
In fractional IMA mode, multiple fractional IMA links are logically gathered into a group with each
fractional IMA link occupying the same number of idle timeslots.
The parameter FRALNKT is used to specify the fractional link mode on the RNC side.

WCDMA RAN
3-15
The fractional ATM/IMA mode are applicable only to the AEUa/AOUc board.
3.5.3 IMA Mode
Overview
IMA mode (WRFD-050304 IMA Transmission for E1T1 or Channelized STM-1/OC-3 on Iub Interface) is
applicable to the Transmission Convergence (TC) sublayer of the physical layer. The IMA function is
implemented by the IMA group, which is composed of either IMA links or fractional IMA links.
All IMA links within an IMA group must be of the same type, either common IMA link or fractional IMA link.
If an IMA group is composed of fractional IMA links, the quantity of timeslots carrying each fractional IMA
link must be identical.
Principles of IMA Mode
Figure 3-17 shows the principles of the IMA mode based on the assumption that each IMA group
contains three E1/T1 links.
 At the transmission end, the IMA group receives the ATM cell stream from the ATM layer and
distributes the cells among the E1/T1 links.
 At the reception end, the IMA group reassembles the cells to restore the original ATM cell stream, and
then transfers the cell stream to the ATM layer.
The physical layer provides high-speed transport channels for ATM cells from the perspective of the ATM
layer.
Figure 3-17 Principles of the IMA mode
In IMA mode, ATM cells, IMA Control Protocol (ICP) cells, and filler cells form an IMA frame to implement
necessary controlling functions.
The length of an IMA frame, m, is defined during the setup of an IMA group. The parameter FRMLEN (at
the RNC)/FRMLEN (at the NodeB) is used to specify the length of an IMA frame.
Figure 3-18 shows an IMA frame. The mapping between the ATM cell and the physical link (that is, the
E1/T1 link) is similar to that in UNI mode.

WCDMA RAN
3-16
Figure 3-18 IMA frame
The IMA mode has the characteristics of scrambling, line coding, 16-timeslot enabling, and clock mode.
The clock mode of an IMA group is defined from the perspective of an IMA group rather than a single link.
For details about clock mode, see Clock Mode. The related parameters are as follows:
 16-timeslot switch: specifies whether to use timeslot 16 or not.
The setting of scrambling switch, line coding method, and 16-timeslot switch at both ends of E1/T1 must
be identical.
The parameters corresponding to IMA mode are shown in Table 3-5.

3.6 Timeslot Cross Connection
The timeslot cross connection function implements cross connections between timeslots on two E1/T1s
at the physical medium (PM) sublayer of the physical layer.
3.6.1 Principles of Timeslot Cross Connection
Figure 3-19 shows an example of timeslot cross connection. The timeslot cross connection device
cross-connects the timeslots on one E1/T1 to the timeslots on the other E1/T1. In the example shown in
the following figure, the device cross-connects slots 2 and 3 on one E1/T1 to slots 4 and 8 on another
E1/T1 respectively.

WCDMA RAN
3-17
Figure 3-19 Example of timeslot cross connection
3.6.2 Function of Timeslot Cross Connection
The AEUa/PEUa/POUc board supports timeslot cross connection. Through the configured timeslot cross
connection, the E1 data in TS A of the source port is transmitted to TS B of the destination port.
Therefore, the timeslot cross connection helps provide a transparent data transmission channel for the
2G equipment or NodeB monitoring equipment.
Figure 3-20 shows implementation of timeslot cross connection.
Figure 3-20 Implementation of timeslot cross connection
Neither the source timeslot nor the target timeslot of a timeslot cross connection can be used by other applications, such
as fractional ATM, IMA, and UNI.
If an E1 link is configured with a timeslot cross connection, the E1 link cannot carry any IMA or UNI link. The other
timeslots on this E1 link can carry fractional ATM or fractional IMA links.
The related parameters of the timeslot-cross connection function are as follows:

 SRCPORTNO: specifies the source port to perform the timeslot-cross connection function.
 SRCTSMASK: specifies the timeslots occupied by the source port.
 DSTPORTNO: specifies the destination port to perform the timeslot-cross connection function.
 DSTTSMASK: specifies the timeslots occupied by the destination port.
3.7 PVC Parameters of the ATM Layer
For configuring the IPoA PVCs, AAL2 paths, SAAL links, or VPCLCX links, the PVC parameters need to
be set.
3.7.1 VPI and VCI
The main characteristics of the ATM technology are multiplexing, switching, and transmitting of ATM
cells. All these operations are performed over Virtual Channels (VCs). A VC and a Virtual Path (VP) are
identified by Virtual Channel Identifier (VCI) and Virtual Path Identifier (VPI) respectively.
Figure 3-21 shows the relation between VC and VP.
 A VC is identified by a VCI. It is a logical connection between ATM nodes and is the channel for
transmitting ATM cells between two or more nodes. The VC is used for the data transmission between
mobile terminals, between networks, or between mobile terminal and network.
 A VP is a group of VCs at a given reference point. The VCs in the group have the same VPI.
Figure 3-21 Relation between VC and VP
3.7.2 Service Type
The ATM services are of five types (WRFD-05030107 CBR, RT-VBR, NRT-VBR, UBR ATM QoS Classes,
WRFD-050305 UBR+ ATM QoS Class): Constant Bit Rate (CBR), Real-Time Variable Bit Rate (RT-VBR),
Non-Real-Time Variable Bit Rate (NRT-VBR), Unspecified Bit Rate (UBR), and UBR_PLUS (UBR+).
Table 3-6 describes the types of service.
Table 3-6 Types of service
Type of Service Description
CBR No error check, flow control, or other processing
RT-VBR Rate of a service with variable-rate data streams and strict real-time requirements,
for example, interactive compressed video (video telephony).
NRT-VBR Rate of a service that is applicable to timing transmission. A service of this type, for
example, e-mail, is relatively insensitive to delivery time or delay.

WCDMA RAN
3-19
Type of Service Description
UBR Rate of a service with no commitment to transmission and no feedback on
congestion. This type of service is ideal for the transmission of IP datagrams. In
congestion, UBR cells are discarded, and no feedback or request for slowing down
the data rate is delivered to the transmission end.
UBR+ UBR+ is an enhancement of UBR with minimum desired cell rate (MDCR)
indication. UBR+ is the most suitable for Iub OAM channel. The MCR of UBR+
ensures the connectivity of OAM connection in the case of Iub transmission
resource congestion, and the best effort service of UBR+ uses the transmission
bandwidth completely.
Table 3-7 describes the characteristics of different ATM services.
Table 3-7 Characteristics of different ATM services
Characteristic CBR RT-VBR NRT-VBR UBR UBR+
Bandwidth guarantee Yes Yes Yes No Yes
Applicability to real-time
communication
Yes Yes No No No
Applicability to bursts of
communication
No Yes Yes No No
Feedback on congestion No No No No No
The ATM service type is also called ATM QoS class. The CBR, RT-VBR, NRT-VBR, or UBR ATM QoS
classes can be configured for AAL2 path, and the UBR+ ATM QoS class is generally used for Iub OAM
connection.
The service types carried on the AAL2 paths can be determined by running the ADD ATMTRF command,
and then the mapping between the service types and the transmission resources for the adjacent node
can be configured by running the ADD TRMMAP command.
3.7.3 ATM Traffic Records
The ATM traffic records are public resources, which can be used by the IPoA PVCs, AAL2 paths, SAAL
links, and VPCLCX links. You need to add the traffic record at the BSC6900 based on the traffic model of
the link on the Iub/Iu-CS/Iu-PS/Iur interface. The ATM traffic records can be configured by the ADD
ATMTRF command.
Traffic Parameters
Traffic parameters refer to the parameters used by each PVC for flow control.
Table 3-8 describes the ATM traffic parameters.
Table 3-8 ATM traffic parameters
Parameter ID Description
TRFX Identifies a traffic record.

WCDMA RAN
3-20
Parameter ID Description
ST Indicates the type of service carried over ATM. CBR and RT-VBR indicate real-time
services, which are usually carried on the user planes of the Iur, Iub, and Iu-CS
interfaces. NRT-VBR and UBR indicate non-real-time services, which are usually
carried on the user plane of the Iu-PS interface.
UT Indicates the unit of PCR, SCR, and MCR.
PCR Indicates the maximum rate of transmitting ATM cells. The value of PCR must be
greater than that of SCR.
SCR Indicates the average rate of transmitting ATM cells over a long time.
MCR Indicates the minimum rate of transmitting ATM cells.
MBS Indicates the maximum number of continuous ATM cells. Generally, the value of MBS
cannot be greater than PCR x CDVT. The value of CDVT can be set as large as
possible within the permission of the delay and delay variation.
CDVT Indicates the maximum tolerable variation in the unit of 0.1 μs.
REMARK Describes the usage of the ATM traffic record.
The traffic rate is indicated in the following ways:
 PCR: applicable when ST is set to CBR and the traffic rate is a constant value.
 Combination of PCR and SCR: applicable when ST is set to RTVBR or NRTVBR.
 MCR: applicable when ST is set to UBR_PLUS.

 In practice, ATM traffic records should be negotiated between the local and the peer equipment.
 The ATM traffic parameters, such as PCR and SCR, should be configured depending on the traffic model in use.
 When configuring ATM traffic records for links, you need to consider the traffic on the interface boards of the BSC6900.
3.8 AAL5
In ATM transport mode, AAL5 connections are used to carry the signaling on the Iub/Iur/Iu interface
(WRFD-05030105 permanent AAL5 connections for control plane traffic). As defined in 3GPP
specifications, UNI-SAAL is used for control plane connections on the Iub interface, and NNI-SAAL is
used for control plane connections on the Iur and Iu interfaces. The AAL5 connections for Iub/Iu-CS/Iur
are set up by configuring the SAAL links.
You can run the ADD SAALLNK command to configure the AAL5 connections on the Iub/Iur/Iu interface.
On the RNC side, when an AAL5 connection is configured, the TXTRFX and RXTRFX parameters need
to be set. The TXTRFX and RXTRFX parameters record the ATM traffic, and they can be configured
through the ADD ATMTRF command.
An SAAL link is carried on an ATM PVC. The parameters CARRYVPI and CARRYVCI are used to
identify the PVCs on the RNC side, and the parameters VPI and VCI are used to identify the PVCs on
the NodeB side. The PVC identifier and other PVC attributes must be negotiated between the BSC6900
and the peer end.
The signaling messages carried on the UNI-SAAL links are classified into NCP, CCP, and ALCAP, and
the signaling messages carried on the NNI-SAAL links are MTP3, as described in Table 3-10.
Table 3-10 Data carried on SAAL links
Data Type Description
NCP The NCP carries common process messages of NBAP over the Iub interface. An Iub
interface has only one NCP.
CCP A CCP carries dedicated process messages of NBAP over the Iub interface. An Iub
interface may have multiple CCPs. The number of CCPs depends on network planning.
ALCAP ALCAP is also called Q.AAL2. Typically, an Iub interface has one ALCAP.
MTP3 MTP3 links are contained in an MTP3 link set. MTP3 links are carried on the SAAL links of
Network-to-Network Interface (NNI) type.
3.9 AAL2 Path
3.9.1 AAL2 Connections and AAL2 Path
The Q.AAL2 module is responsible for dynamically setting up and releasing AAL2 connections between
the BSC6900 and the peer end. The peer end can be a NodeB, a CS CN node, or a neighboring
BSC6900. PATHID specifies the ID of an AAL2 path, and the PATHID of the same AAL2 path configured
between two AAL2 nodes must be the same. An AAL2 path contains multiple AAl2 connections. CID
specifies the ID of an AAL2 connection on the path. The CID state can be Busy or Idle. If the CID is in the
busy state, the CID carries traffic; if the CID is in the idle state, no traffic is carried on it.
The AAL2 paths can be configured for the Iub/Iu-CS/Iur interface (WRFD-05030104 Dynamic AAL2
Connections on Iub/IuCS/Iur Interface).
Figure 3-22 shows the relation between an AAL2 path and AAL2 connections on the Iub interface.

WCDMA RAN
3-22
Figure 3-22 Relation between an AAL2 path and AAL2 connections
According to different traffic classes (conversational, streaming, interactive, and background), the
following types of AAL2 path can be configured:
 CBR
 RT-VBR
 NRT-VBR
 UBR
According to different types of service (R99, HSDPA, and HDUPA), the following types of AAL2 path can
be configured:
 R99
 HSPA
 SHARE
The AAL2 path can be configured through the ADD AAL2PATH command. On the RNC side, when an
AAL2 path is configured, the TXTRFX and RXTRFX parameters need to be set. They determine the type
of path. The TXTRFX and RXTRFX parameters record the ATM traffic, and they can be configured
through the ADD ATMTRF command. For details, see section 3.7.3 "ATM Traffic Records."
An AAL2 path is carried on a PVC. The parameters VPI and VCI are used to identify the PVCs. The PVC
identifier and other PVC attributes must be negotiated between the BSC6900 and the peer end.
3.9.2 AAL2 Route
An AAL2 path may reach not the destination node but an adjacent node. In this case, AAL2 routes can
be configured to reach the destination node. The AAL2 route to an ATM node can be configured through
the ADD AAL2RT command.
Figure 3-23 shows an example of the AAL2 route.
Figure 3-23 Example of the AAL2 route

WCDMA RAN
3-23
 Even if the destination node and the adjacent node are the same, an AAL2 route needs to be configured.
 The AAL2 route cannot be configured for the adjacent node of the IUPS type.
3.10 MTP3
3.10.1 MTP3 Links
MTP3 links are contained in an MTP3 link set. MTP3 links are carried on the SAAL links of
Network-to-Network Interface (NNI) type. You can run the command ADD MTP3LKS to specify an MTP3
link set, and then run the command ADD MTP3LNK to add the MTP3 links by using the parameter
SIGLKSX.
MTP3 Links for Iu-CS Interface
The configuration of MTP3 links between the BSC6900 and the MSC server depends on the networking
between the MSC server and the BSC6900:
 If the MSC server is directly connected to the BSC6900, at least one MTP3 link is required for the MSC
server (IUCS_RANAP signaling point). It is recommended that more than one MTP3 link be
configured.
 If the MSC server is connected to the BSC6900 through the MGW, the MSC server (IUCS_RANAP
signaling point) does not require any MTP3 link.
 If the MSC server is connected to the BSC6900 not only directly but also through the MGW, as shown
in Figure 3-24, the MSC server (IUCS-RANAP) requires at least one MTP3 link. It is recommended
that more than one MTP3 link be configured.
Figure 3-24 Example of connections between the MSC server and the BSC6900
MTP3 Links for Iu-PS Interface
An Iu-PS interface requires at least one MTP3 link. It is recommended that more than one MTP3 link be
configured.
MTP3 Links for Iur Interface
The configuration of MTP3 links depends on the networking between the BSC6900 and the neighboring
BSC6900:
 If the BSC6900 is directly connected to the neighboring BSC6900, the Iur interface requires at least
one MTP3 link. It is recommended that more than one MTP3 link be configured.

WCDMA RAN
3-24
 If the BSC6900 is connected to the neighboring BSC6900 through a Signaling Transfer Point (STP),
no MTP3 link is required.
It is recommended that the SAAL links of NNI type be evenly distributed to the CPUS subsystems in the
MPS/EPS so that the signaling exchange can be reduced between the CPUS subsystems.
3.10.2 Types of MTP3 DSPs
The BSC6900 supports seven types of Destination Signaling Point (DSP): IUCS, IUCS_ALCAP,
IUCS_RANAP, IUPS, IUR, STP, and AAL2SWITCH. DSPs of different types have different meanings.
Table 3-11 describes the types of DSP.
Table 3-11 Types of DSP
DSP Type Description
IUCS R99 MSC DSP. The IUCS DSP has the control plane functions of both radio
network layer and transport network layer on the Iu-CS interface.
IUCS_ALCAP R4 MGW DSP. The IUCS_ALCAP DSP has the control plane functions of the
transport network layer on the Iu-CS interface.
IUCS_RANAP R4 MSC server DSP. The IUCS_RANAP DSP has the control plane
functions of the radio network layer on the Iu-CS interface.
IUPS Signaling point in the Iu-PS control plane
IUR Other BSC6900 signaling points
STP Signaling transfer point
AAL2SWITCH AAL2 transfer point
3.10.3 Signaling Route Mask and Signaling Link Mask
The number (represented by n) of 1s in a signaling route mask determines the maximum number of
routes (2n
). For example, B0000 indicates that there is at most one route. B0001 or B1000 indicates that
there are at most two routes.
The number (represented by n) of 1s in a signaling link mask determines the maximum number of links
(2n
). For example, B0000 indicates that there is at most one link. B0001 or B1000 indicates that there
are at most two links.
The result of the logical AND operation on the signaling link mask and the signaling route mask must be
0, as shown in Figure 3-25.
Figure 3-25 Relation between signaling link mask and signaling route mask

WCDMA RAN
3-25
3.11 IPOA PVC
IPOA is a technology in which IP packets are transmitted over the ATM transport network. Essentially,
the ATM links over each interface are carried over PVCs. The IPoA PVCs on the Iub interface are used
to transmit the OM information of a NodeB. In this case, the IPoA PVC is called the management plane
IPoA PVC. The IPoA PVC on the Iu-PS interface is a PVC to the SGSN gateway.
The IPOA PVC can be configured through the ADD IPOAPVC command. If the parameter PEERT is set
to IUB, the IPOA link can only be used as an OM channel. The parameters CARRYVPI and CARRYVCI
are used to identify the PVCs.
When an IPOA PVC is configured, the TXTRFX and RXTRFX parameters need to be set. The TXTRFX
and RXTRFX parameters record the ATM traffic, and they can be configured through the ADD ATMTRF
command.
Users can run the ADD OMCH command to enable a third-party device to access the OM channel of a
NodeB. The OM channel forwards the OM data of the third-party device. The OM data is routed from the
NodeB to the M2000 through IPOA. The NodeB OM IP address serves as the default gateway IP
address for the third-party device.
For details about relevant parameters, see section 3.2.5 "OM Channel Configuration on the NodeB Side
" in the IP RAN Feature Parameter Description.
3.12 F5
Huawei supports operations on ATM OAM F5 end-to-end flows specified in ITU I.610 (WRFD-05030110
F5):
 Fault management
− AIS: alarm indication signal
− RDI: remote defect indication
− CC: continuity check and loopback
 Performance management
− Forward monitoring
− Backward reporting
 Activation and deactivation
The CC can be activated to monitor the end-to-end AAL2 path virtual connect link (VCL) and Iu-PS user
plane VCL. When one VCL for AAL2 path or Iu-PS GTPU is loss of continuity (LOC), AIS, or RDI, this
VCL is blocked. Then the service is established on other alternative VCLs to prevent the failure of the
call. You can run the ACT VCLCC command to activate the CC function and the DEA VCLCC command
to deactivate the CC function. When the parameter VCLTYPE is set to CC, the CC function is activated.
Huawei also supports proprietary delay detection function. When an NE receives a detection start
command from the NMS, it starts detecting delay on the current AAL2 link or AAL5 link and periodically
reports the delay to the NMS. The 8-byte reserved IE (LB IE) in the loopback message is used to store
the message transmission time. When an NE receives the loopback message, it calculates the delay
based on the time difference between transmission and reception.

4 ATM Transmission Resources
ATM transmission resources can be classified into physical resources, logical ports, resource groups,
and paths. The transmission resources for Iub/Iu/Iur interfaces vary according to different networking.
Huawei supports the following types of ATM transmission:
 ATM over E1T1 on Iub interface (WRFD-05030101 ATM over E1T1 on Iub interface)
 ATM over channelized STM-1/OC-3 on Iub interface (WRFD-05030102 ATM over channelized
STM-1/OC-3 on Iub interface)
 ATM over non-channelized STM-1/OC-3c on Iub/Iu/Iur interface (WRFD-05030103 ATM over
non-channelized STM-1/OC-3c on Iub/Iu/Iur interface)
For details about the ATM transmission resources, see "Transmission Resources" in the Transmission
Resource Management Feature Parameter Description.

5 ATM Transmission Resource Management
For ATM transport, Huawei provides the following transmission resource management:
 Admission control (WRFD-05030106 Call Admission Based on Used AAL2 Path Bandwidth), which is
used to allow more users to be admitted with the QoS guaranteed.
 Transmission resource mapping, in which the CBR, RT-VBR, NRT-VBR, and UBR ATM QoS classes
are used to implement differentiated services.
 Iub overbooking (WRFD-050405 Overbooking on ATM Transmission, WRFD-050406 ATM QoS
Introduction on Hub Node B (Overbooking on Hub Node B Transmission)), which is used to improve
the usage efficiency on ATM transport scenario

6.5.2 Procedure
Step 1 Run the BSC6900 MML command ACT VCLCC to activate the VCL CC or loopback function for
a link. To activate the function for multiple links, run this command repeatedly. There are three
types of links, that is, SAALLNK, AAL2PATH, and IPOAPVC.
Step 2 Run the BSC6900 MML command ACT VCLPM to activate the VCL PM function for a link. To
activate the function for multiple links, run this command repeatedly. There are three types of
links, that is, SAALLNK, AAL2PATH, and IPOAPVC.
Step 1 Run the BSC6900 MML command DSP VCLCC to query the CC result of a VCL.
− If the VCL CC is activated and the PVC is functional, the SINK activated state and SOURCE
activated state are UP, and LOC, AIS, and RDI alarm state is normal.
− If the loopback is activated and the PVC is functional, the loopback query result is UP, and LOC, AIS,
and RDI alarm state is normal.
Step 2 Run the BSC6900 MML command DSP VCLPM to query the PM result of a VCL.
− If the VCL PM is activated, the SINK activated state and SOURCE activated state are PM_UP, and
PM Active Fail Alarm is Normal.
Step 1 Run the BSC6900 MML command DEA VCLCC to deactivate the VCL CC or loopback function
for a link. To deactivate the function for multiple links, run this command repeatedly. There are
three types of links, that is, SAALLNK, AAL2PATH, and IPOAPVC.
Step 2 Run the BSC6900 MML command DEA VCLPM to deactivate the VCL PM for a link. To
deactivate the function for multiple links, run this command repeatedly. There are three types of
links, that is, SAALLNK, AAL2PATH, and IPOAPVC.

6.6.2 Procedure
Step 1 Run the MML command ADD ATMTRF (CME single configuration: NodeB Configuration
Express > IUB_RNC > ATM Transport > ATM Traffic Record; CME batch modification center: not
supported) to add an ATM traffic record of the UBR+ class. To add more ATM traffic records, run
this command repeatedly.
Step 1 Run the MML command LST ATMTRF to query the ATM traffic configuration.
Expected result: The query result is consistent with the configuration information.
Step 1 Run the MML command RMV ATMTRF (CME single configuration: NodeB Configuration
Express > IUB_RNC > ATM Transport > ATM Traffic Record; CME batch modification center: not
supported) to delete an ATM traffic record of the UBR+ class. To delete more ATM traffic records,
run this command repeatedly.

are used by the upper
layers of the ATM layer.
The upper layers consist
of the SAAL link, AAL2
path, and IPoA PVC.
Each ATM traffic record is
uniquely numbered within
a BSC6900 by using an
ATM traffic record index.
An ATM traffic record
index ranges from 100 to
1999 (1 to 99 are reserved
for internal use). The
numbering is not
necessarily consecutive.
Specify different number
ranges for different
interfaces. For example,
specify the range of 100 to
199 for ATM traffic record
indexes over Iub, the
range of 200 to 299 for
over Iur, the range of 300
to 399 for ATM traffic
record indexes over
Iu-CS, and the range of
400 to 499 for ATM traffic
record indexes over
Iu-PS.
