2 Overview
2.1 Background
The proportion of video services on a network is increasing continuously. When the cell load
is heavy, user experience with video playback deteriorates. For example, the video initial
buffering time is extended, and the number of video freezes increases. The Video Service
Rate Adaption feature reduces the video buffering time and the number of video freezes to
improve user experience.
When a considerable quantity of download services, such as P2P download, FTP download,
and HTTP download, are provided in a cell, these download services affect user experience
with high-priority services in the cell, such as web browsing, video playback, and over the
top (OTT) services. The Busy-Hour Download Rate Control feature decreases the priority of
download services, thereby reducing the resource preemption of download services on high-
priority services and improving user experience with high-priority services.
2.2 Introduction
The Busy-Hour Download Rate Control and Video Service Rate Adaption features rely on a
service awareness device deployed in the evolved packet core (EPC) or a third-party service
awareness device. The service awareness device identifies download services and video
services and sets differentiated services code points (DSCPs) in the service packets based on
the identification results. The eNodeB parses these DSCPs to obtain the identification results
and performs differentiated QoS guarantee for download and video services.
Using the service awareness device, the Video Service Rate Adaption feature identifies
HTTP-based video services and allocates required bandwidth to these services. This ensures
smooth video playback and improves user experience.
DSCP
The service awareness device sets DSCPs based on service type identification results. The
eNodeB parses the DSCPs to obtain the identification results.

SGBR
SGBR is short for service guaranteed bit rate, which is defined by Huawei. The SGBR
guarantees the rate of video services on non-GBR bearers and increases the priorities for
video services whose rates are lower than the SGBR.
SMBR
SMBR is short for service maximum bit rate, which is defined by Huawei. The SMBR
controls the rate of download services on non-GBR bearers and decreases the priorities for
download services whose rates have exceeded the SMBR. When a cell has sufficient
resources and the SMBR is set to a small value, the download service rate may exceed the
SMBR.
2.3 Benefits
After the Busy-Hour Download Rate Control feature is enabled, the rate of download services
is restricted during busy hours to spare air interface resources for high-priority services and
improve user experience with high-priority services.
Enabling the Video Service Rate Adaption feature reduces the video buffering time,
guarantees the video service rate, and reduces the number of video freezes.

Table 2-1 Functions of NEs
NE Function
Service awareness device The service awareness device identifies
service types such as video and download
services, and sets DSCPs in service packets
based on the identification results so that the
eNodeB can obtain the results.
eNodeB The eNodeB identifies these DSCPs and
performs differentiated scheduling based on
the service types (such as video and
download services) configured by operators
and corresponding QoS policies.
3 Technical Description
3.1 Introduction
Operators' networks provide diversified services. These services have different experience
requirements. Besides, operators are transforming from pipeline operations to experience-
oriented operations. DSCP-based service differentiation is fundamental to experience-
oriented operations, and Video Service Rate Adaption and Busy-Hour Download Rate
Control features are specific implementation of service differentiation.
3.2 Principles
3.2.1 Service Type Identification and DSCP Setting
Operators integrate a service awareness device into the S-GW/P-GW or deploy a third-party
service awareness device for service type identification. After identifying service types, the
service awareness device sets the DSCPs in service packets to different values based on the
identification results. DSCPs are in the IP headers of service packets, as shown in Figure 3-1.

Figure 3-1 DSCP position
NOTE:
After the Video Service Rate Adaption and Busy-Hour Download Rate Control features are
enabled:
 Operators need to configure DSCPs for services on the eNodeB. The configured
DSCP values and corresponding service types must be the same as those configured
on the service awareness device. For example, if the service awareness device
identifies a video service and sets the DSCP to 40, the DSCP value 40 must be
configured for video services on the eNodeB.
 If DSCPs are not configured for services on the eNodeB or the DSCP configuration
on the eNodeB is different from the DSCP configuration on the service awareness
device, the eNodeB cannot map the DSCPs in received service packets onto priority
queues and the packets are put into priority queue 0 by default.
If the DSCP value of service packets is 0, the eNodeB cannot map the DSCPs in
received service packets onto priority queues and the packets are put into priority
queue 0 by default.
 In RAN sharing scenarios, it is required that operators configure the same or totally
different DSCPs on their separate service awareness devices. For example, if operator
A configures the DSCP value 40 for video services and the DSCP value 10 for
download services, operator B is allowed to configure the DSCP value 42 for video
services and the DCSP value 12 for download services. If operator A configures the
DSCP value 40 for video services, operator B is not allowed to configure the DSCP
value 40 for download services.
3.2.2 Differentiated Scheduling

The Busy-Hour Download Rate Control and Video Service Rate Adaption features are
implemented based on differentiated scheduling on the eNodeB. The options of the
CELLALGOSWITCH.ServiceDiffSwitch parameter must be selected to enable the
features.
Differentiated scheduling consists of PDCP-based differentiated queue scheduling and Media
Access Control (MAC) scheduling. (PDCP is short for Packet Data Convergence Protocol.)
PDCP-based differentiated queue scheduling implements scheduling of multiple services
within a bearer. MAC scheduling implements scheduling among bearers. Figure 3-2 shows
the overall scheduling scheme.
Figure 3-2 Differentiated scheduling scheme
PDCP-based differentiated queue scheduling involves eight queues, for which weights can be
set by specifying the values of the SERVICEDIFFSETTING.QueueWeight0 to
SERVICEDIFFSETTING.QueueWeight7 parameters. In PDCP-based differentiated
queue scheduling, the eNodeB dynamically calculates the overall service weight based on the
queue weight and queue rate. The overall service weight has an impact on the MAC
scheduling weight.
The scheduling priority factors (indicated by STANDARDQCI.DlschPriorityFactor)
carried by each non-GBR service are different. Therefore, the priorities for different services
are calculated by the following formula: STANDARDQCI.DlschPriorityFactor x Overall
service weight. In practical use, operators may use different non-GBR bearers to implement
the QoS for gold, silver, and bronze subscribers. The product of the overall service weight
and scheduling priority factors must be considered during service planning to check whether
the product meets the QoS requirements of operators on subscribers.
NOTE:
PDCP-based differentiated queue scheduling applies only to non-GBR services.
3.2.3 Video Service Rate Adaption
When the network is congested, the video service rate for some UEs with good radio signal
quality is lower than the SGBR and the video buffering time is long or video freezes occur. In

this case, the Video Service Rate Adaption feature ensures that the video service rate
approximates the SGBR if the purchased video traffic volume is sufficient, thereby
improving user experience.
When the network load is light and UEs playing videos receive good-quality radio signals,
the video service rates for these UEs reach or exceed the SGBR. In this situation, the eNodeB
does not decrease the bearer weights to limit the video service rates to the SGBR.
When the VideoRateAdaptSwitch(VideoRateAdaptSwitch) option of the
CELLALGOSWITCH.ServiceDiffSwitch parameter is selected, the Video Service Rate
Adaption feature is enabled.
The video service rate is ensured by means of initial acceleration in the first phase and
normal-rate guarantee in the second phase. When the
IPSERVICEQOS.QosPolicyTimeSwitch parameter is set to ON(ON), phase-based
service rate guarantee is enabled. The following describes initial acceleration and normal-rate
guarantee.
Initial Acceleration
When a video is opened, the initial service rate is low and it takes some time before the video
playback starts. To accelerate the initial video download rate and reduce the video buffering
time, the eNodeB increases the scheduling weight for video services so that the video
download rate soon reaches the target rate (SGBR 1) in the first phase shown in Figure 3-3.
When a video stream initially starts, the eNodeB uses the first-phase QoS policy specified by
the IPSERVICEQOS.FirQosPolicyId parameter and accelerates the service rate for a
duration specified by the IPSERVICEQOS.FirQosPolicyTimeLength parameter. The
IPSERVICEQOS.FirQosPolicyTimeLength parameter can be adjusted based on the
acceleration effect, and you are advised to set this parameter to 8s. If the initial video
download takes a long time, increase the value of the
IPSERVICEQOS.FirQosPolicyTimeLength or QOSPOLICY.DlSgbr parameter for
initial acceleration. It is recommended that the QOSPOLICY.DlSgbr parameter be set to a
value two times of the video bitrate for initial acceleration.
You are advised not to set the IPSERVICEQOS.FirQosPolicyTimeLength parameter to
an excessively large value to prevent waste of radio resources. Similarly, you are advised not
to set the SGBR to an excessively large value for the normal-rate guarantee phase to prevent
waste of radio resources.
Normal-Rate Guarantee
After initial acceleration, the eNodeB uses the second-phase QoS policy specified by the
IPSERVICEQOS.SecQosPolicyId parameter to ensure the service rate. When the service
rate is less than SGBR 2 shown in Figure 3-3, the eNodeB increases the scheduling weight
for the bearer carrying the video service. When the service rate reaches or exceeds SGBR 2,
the eNodeB decreases the scheduling weight to prevent excessive bandwidth usage. If the
resources are sufficient, the eNodeB ensures that the service rate is not less than SGBR 2.
Admission control is not performed based on SGBR 2, which is not absolutely guaranteed.

It is recommended that the QOSPOLICY.DlSgbr parameter be set to a value 1.1 to 1.2
times of the video bitrate for normal-rate guarantee.
NOTE:
Different types of video services have different requirements for resolution and code formats
and therefore requires different video bitrates. If the service awareness device can
differentiate video bitrates, it is recommended that the service awareness device set different
DSCPs for video services of different bitrates so that different SGBRs can be configured for
video services of different bitrates. If the service awareness device cannot differentiate video
bitrates, it is recommended that DlSgbr be set based on the large video bitrates used by OTT
video websites.
Figure 3-3 Video playback acceleration
3.2.4 Busy-Hour Download Rate Control
When the DownLoadRateLimitSwitch(DownLoadRateLimitSwitch) option of the
CELLALGOSWITCH.ServiceDiffSwitch parameter is selected, the Busy-Hour
Download Rate Control feature is enabled.
SMBR-based rate control is implemented for low-value services such as P2P download, FTP
download, and HTTP download. When the download service rate exceeds the download
service rate control threshold specified by the QOSPOLICY.DlSmbr parameter, the
eNodeB reduces the number of packets in the download service queue or decreases the
download service queue weight to decrease the download service rate until the download is
complete. When the download service rate of a UE has not reached the value of the
QOSPOLICY.DlSmbr parameter, the eNodeB does not decrease the download service rate
of the UE. It is recommended that the QOSPOLICY.DlSmbr parameter be set to the
average download service rate achieved before the Busy-Hour Download Rate Control
feature is enabled. The parameter value can be adjusted based on the network plan.
This configured SMBR is only a threshold for rate control and the download service rate is
not strictly kept below the SMBR. When resources are sufficient, good user experience with
download services can be ensured. During busy hours or when a large number of high-
priority users are using services, the SMBR-based rate control can reduce the amount of

resources occupied by download services and thereby improve user experience with high-
priority services.
If the SMBR is greater than the download service rate achieved before the Busy-Hour
Download Rate Control feature is enabled, the eNodeB does not decrease the scheduling
weight for download services.
Figure 3-4 Download service rate control (1)
In Figure 3-4, the SMBR is set to a value close to or slightly below the maximum of the busy-
hour average download service rates achieved before the Busy-Hour Download Rate Control
feature is enabled. Before the Busy-Hour Download Rate Control feature is enabled, the
download service rate fluctuates around the SMBR, as indicated by line 1. After the Busy-
Hour Download Rate Control feature is enabled, the eNodeB decreases the scheduling weight
for the download service when the download service rate exceeds the SMBR. As a result, the
download service rate also decreases, as indicated by line 2.
Figure 3-5 Download service rate control (2)
In Figure 3-5, the SMBR is set to an excessively small value, for example, a value less than
30% of the maximum of the busy-hour average download service rates achieved before the
Busy-Hour Download Rate Control feature is enabled. Before the Busy-Hour Download Rate
Control feature is enabled, the download service rate is about two times the SMBR, as
indicated by line 3. After the Busy-Hour Download Rate Control feature is enabled, the

download service rate decreases when the download service rate exceeds the SMBR but is
still greater than the SMBR, as indicated by line 4.
3.2.5 DSCP and QoS Policy Configurations
QoS service information is configured for DSCPs on the eNodeB to implement DSCP-based
service differentiation.
QoS service information includes QoS policies and the mappings between DSCPs and QoS
policies. A QoS policy, which is set by configuring a QosPolicy MO, defines a priority queue
(PriQueueId) and the guaranteed maximum bit rate (DlSgbr and DlSmbr) for a type of
service. The mappings between DSCPs and QoS policies are set by configuring
IpServiceQos MOs.

5 Network Impact
System Capacity
This feature decreases the scheduling weight for download services and therefore decreases
the download service rate. As a result, the rate of high-priority services increases.
The change in cell capacity is related to the radio environment of the UEs using download
services and the proportion of the download traffic in the cell. If the UEs using download
services are located in areas with good signal quality, the cell capacity decreases. If the UEs
using download services are located in areas with poor signal quality, the cell capacity
increases. When the SMBR is set to a small value, the download service rate decreases
obviously, resulting in a big change in the cell capacity.
For example, cell congestion is simulated for a cell for which the SMBR is set to 500 kbit/s.
There are three UEs (UE A, UE B, and UE C) in the cell. UE A is located at the cell center,
UE B is located at the cell edge, and UE C is located halfway between the cell center and cell
edge. Assume that UE A is using download services, UE B is using video services, and UE C
is using other services. Before the Busy-Hour Download Rate Control feature is enabled, the
cell throughput is 2.2 Mbit/s. After the Busy-Hour Download Rate Control feature is enabled,
the cell throughput is 1.8 Mbit/s, with a 14% decrease in cell capacity. Assume that UE A is
using video services, UE B is using download services, and UE C is using other services. The
cell capacity does not change after the Busy-Hour Download Rate Control feature is enabled.
The reason for the unchanged cell capacity is that the download services are started later, the
download service rate is less than the SMBR, and therefore the scheduling weight is not
decreased for the download services.
Network Performance
This feature decreases the scheduling weight for download services and therefore decreases
the download service rate. If a download peak rate is set, you are advised not to enable this
feature during download service performance evaluation.

System Capacity
This feature increases the scheduling weight for video services and therefore ensures the
video service rate. As a result, the rate of low-priority services decreases. The change in cell
capacity is related to the radio environment of the UEs using video services and the
proportion of the video traffic in the cell.
If the UEs using video services are located in areas with good signal quality, the cell capacity
increases. If the UEs using video services are located in areas with poor signal quality, the
cell capacity decreases. When the SGBR is set to a large value, the video service rate
increases obviously, resulting in a big change in the cell capacity.
For example, cell congestion is simulated for a cell for which the SGBR is set to 2 Mbit/s.
There are three UEs (UE A, UE B, and UE C) in the cell. UE A is located at the cell center,
UE B is located at the cell edge, and UE C is located halfway between the cell center and cell
edge. Assume that UE A is using download services, UE B is using video services, and UE C
is using other services. Before the Video Service Rate Adaption feature is enabled, the cell
throughput is 2.2 Mbit/s. After the Video Service Rate Adaption feature is enabled, the cell
throughput is 1.5 Mbit/s, with a 32% decrease in cell capacity. Assume that UE A is using
video services, UE B is using download services, and UE C is using other services. The cell
capacity increases by 10% after the Video Service Rate Adaption feature is enabled.
Network Performance
This feature increases the scheduling weight for video services, ensuring that the video
service rate approximates the SGBR. When the amount of downlink services required by
various types of services in a cell is greater than the available amount of downlink resources
in the cell, this feature decreases the rates of other non-GBR services and increases the
average GBR service delay without affecting the GBR. When the amount of downlink
services required by various types of services in a cell is less than the available amount of
downlink resources in the cell, this feature does not affect other types of services.
Enabling the Video Service Rate Adaption feature reduces the video buffering time,
guarantees the video service rate, and reduces the number of video freezes.
For example, cell congestion is simulated for a cell for which the first-phase SGBR is set to
2.5 Mbit/s. In the cell, there are three UEs separately performing FTP download, P2P
download, and video services. After the Video Service Rate Adaption feature is enabled, the
initial video download delay decreases by 35%.
6 Engineering Guidelines
6.1.1 When to Use Busy-Hour Download Rate Control

The Busy-Hour Download Rate Control feature decreases the traffic volume proportion of
download services in a cell and improves user experience with high-priority services. If the
traffic volume of download services in a cell accounts for 20% of the total traffic volume in
the cell regardless of whether this occurs during busy hours or off-peak hours, you are
advised to enable the Busy-Hour Download Rate Control feature. After this feature is
enabled, the eNodeB decreases the download service rate when the download service rate
exceeds the SMBR. If the cell is heavily loaded, the download service rate decreases
considerably. If the cell is lightly loaded, the download service rate decreases slightly. It is
recommended that the SMBR be set to the average download service rate achieved before
this feature is enabled.
The SMBR value depends on operators' policies in controlling download services. The cell
average rate during busy hours can be used as a reference for SMBR. It is recommended that
the smaller value between operators' expected rate limit and cell average rate during busy
hours be used as the SMBR value.
This feature relies on a service awareness device deployed in the EPC or a third-party service
awareness device to identify service types. Before using this feature, verify that the service
awareness device can identify major services (for example, download services) on the
operator's network and encrypted services such as HTTPS. If the service awareness device
cannot identify the major services or encrypted services, you are advised not to use this
feature.
Before using this feature, obtain the service distribution statistics collected by the service
awareness device and the traffic volume proportion of download services. For example, a
Huawei service awareness device deployed in the EPC can use EPSN seven-layer parsing
performance counters to collect the statistics.
(Optional) Collect service key quality indicator (KQI) information.
If the operator's EPC is capable of KQI evaluation or an independent KQI evaluation device
is deployed, use the related EPC device or the KQI evaluation device to obtain downloading
KQIs, such as file download transmission rate. If the operator's network is not capable of KQI
evaluation, drive test is used and download services are performed on UEs to obtain the
download service rate.

6.2.1 When to Use Video Service Rate Adaption
The gain provided by this feature varies with the cell load and the proportion of video
services. Use Video Service Rate Adaption in the following scenarios:
 The video traffic volume in a cell accounts for 40% or less of the total traffic volume
in the cell and the video service rates for some UEs are less than the SGBR.
 During busy hours, the average single-UE throughput is less than 1.5 Mbit/s in a cell
and the cell load is high, for example, the physical resource block (PRB) usage is
greater than 60%.
 When video services are enabled and the video services to be guaranteed accounts for
high proportion (such as 20%), it is recommended that service identification be
performed on delay-sensitive services such as web services and higher priorities are
used to guarantee delay-sensitive services.

 It is recommended that the QosPolicy.DlSgbr parameter be set to a value two times
of the video bitrate for initial acceleration. You are advised not to set the SGBR for
video services to an excessively large value to prevent waste of radio resources.
 It is recommended that the QosPolicy.DlSgbr parameter be set to a value 1.1 to 1.2
times of the video bitrate for normal rate guarantee. You are advised not to set the
SGBR for video services to an excessively large value to prevent waste of radio
resources.
 The initial acceleration time can be configured according to site requirements. It is
recommended that this parameter be set to 8s. You are advised not to set this
parameter to an excessively large value to prevent waste of radio resources.
This feature relies on a service awareness device deployed in the EPC or a third-party service
awareness device to identify service types. Before using this feature, verify that the service
awareness device can identify major services (for example, video services) on the operator's
network and encrypted services such as HTTPS. If the service awareness device cannot
identify the major services or encrypted services, you are advised not to use this feature.
Before using this feature, obtain the service distribution statistics collected by the service
awareness device and the traffic volume proportion of video services. For example, a Huawei
service awareness device deployed in the EPC can use EPSN seven-layer parsing
performance counters to collect the statistics.
You need to obtain the video bitrates that require adjustment from OTT video websites or the
service awareness device and set the DlSgbr parameter for this feature based on the obtained
video bitrates. If video services with different resolution are performed on a network, it is
recommended that the video bitrate with the highest proportion acts as the reference for
SGBR.
The following table lists common video bitrate, which is for reference only.
Video Type Average Bitrate of
Videos (kbit/s)
Minimum Bitrate of
Videos (kbit/s)
Maximum Bitrate of
Videos (kbit/s)
360P 590 350 800
480P 1500 1000 2500
720P 2400 1000 4000
1080P 6000 4000 8000
It is recommended that average busy-hour single-user throughput in a cell be used if the
bitrate of video on a network is unavailable.
(Optional) Collect service key quality indicator (KQI) information.
If the operator's EPC is capable of KQI evaluation or an independent KQI evaluation device
is deployed, use the related EPC device or the KQI evaluation device to obtain video KQIs,

such as video stream initial buffering time and decrease in the video freezes in a cell, and use
the video KQIs to determine whether to use this feature and to evaluate the feature gain.
If the operator's network is not capable of KQI evaluation, drive test is used. By doing this,
video services are performed on UEs, the video play situation is observed to record the
following items: interval between video start to video image display, video stall times.
Measures such as screen recording and videotaping can be used to facilitate statistics and
analysis.

Adjusting the Queue Weight for Video Services
In addition to SGBR adjustment, the queue weight for video services can be adjusted to
increase the scheduling priority of video services. Before you adjust the weight, you are
advised to run the LST SERVICEDIFFSETTING command to query the current queue
weights to ensure that the sum of the weights does not exceed 100 after the adjustment. To
adjust the queue weight for video services, run the following command:
MOD SERVICEDIFFSETTING: QueueWeight6=30;
None
