RAN Rate Control 2 Overview of Rate Control


2 Overview of Rate Control

Rate control triggers rate decrease, rate increase, or handover according to the resource consumption conditions to ensure the QoS, maintain system stability, and improve system capacity.

2.1 Service Introduction Rate control is mainly used to control the rates of Adaptive Multi-Rate (AMR)/Adaptive Multi-Rate – Wideband (AMR-WB) services and Best Effort (BE) services.

2.1.1 AMR/AMR-WB Services AMR/AMR-WB services are 3G speech services. For AMR services, the codec rates can be adjusted according to the change of radio environments to achieve better speech quality. AMR services are classified into Adaptive Multi-Rate – Narrowband (AMR-NB) services and AMR-WB services. Their codec rates are as follows:

l AMR-NB services have eight codec rates: 4.75 kbit/s, 5.15 kbit/s, 5.9 kbit/s, 6.7 kbit/s, 7.4 kbit/s, 7.95 kbit/s, 10.2 kbit/s, and 12.2 kbit/s.

l AMR-WB services have nine codec rates: 6.6 kbit/s, 8.85 kbit/s, 12.65 kbit/s, 14.25 kbit/s, 15.85 kbit/s, 18.25 kbit/s, 19.85 kbit/s, 23.05 kbit/s, and 23.85 kbit/s.

The voice sampling frequency and bandwidth of AMR-WB services are higher than those of AMR-NB services. Thus, compared with AMR-NB services, AMR-WB services provide better speech quality.

2.1.2 BE Services BE services consist of interactive services and background services. The rates of BE services fluctuate greatly. Adjusting service rates dynamically according to user's activities can improve the resource usage on the Uu interface. Adjusting service rates dynamically according to radio environments can improve the stability of radio links.

RAN Rate Control 2 Overview of Rate Control


2.2 Procedure of Rate Control The procedure of rate control is as follows: Firstly, measurement control is performed, that is, the link quality, traffic volume, and terminal activity are measured. Secondly, service rates are adjusted or link stability control is performed according to the measurement results.

2.2.1 Measurement Control In the measurement phase, the RNC sends a measurement control message to the terminal or cell. The RNC, cell, and terminal perform measurement and report measurement events and results. The measurement items consist of TX power, uplink (UL) BLER, downlink (DL) retransmission rate, traffic volume, and throughput.

The RNC learns about the stability of AMR/AMR-WB services from the measured UL and DL TX power.

The RNC learns about the UL stability of BE services from the UE TX power and DPDCH BLER. It learns about the DL stability of BE services from the DPDCH TX power and the retransmission rate of RLC PDUs.

The RNC learns about the traffic volume from the RLC buffer occupancy, learns about the throughput from the traffic volume measured by the MAC-d, and learns about the terminal activity from the traffic volume or throughput.

2.2.2 Rate Adjustment In the rate adjustment phase, the RNC learns about the link quality, traffic volume, and terminal activity from the measurement results, chooses a rate adjustment method, and then reconfigures service rates through the signaling procedure.

The rate adjustment methods are AMRC/AMRC-WB and Dynamic Channel Configuration Control (DCCC).

AMRC/AMRC-WB Huawei RAN uses the AMRC/AMRC-WB function to adjust AMR codec rates. This function is implemented by the RNC. It dynamically adjusts the codec rates according to the TX power or cell load to achieve the balance among the system load, link stability, and QoS. The UL AMRC/AMRC-WB function and the DL AMRC/AMRC-WB function work independently.

DCCC Rate control for BE services is implemented through the DCCC function. This function is implemented by the RNC. It controls the rates of BE services according to the traffic volume, throughput, radio link quality, or cell congestion state. The UL DCCC function and the DL DCCC function work independently.

2.2.3 Link Stability Control Link stability control is implemented by the RNC. Excessively high TX power means that associated links are unstable. In this case, link stability control is performed through rate decrease, inter-frequency handover, or inter-RAT handover to ensure link stability and the QoS.

Rate decrease in link stability control is implemented through power-based rate decrease in AMRC/AMRC-WB or rate decrease in DCCC.

RAN Rate Control 3 Measurement Control


3 Measurement Control

Measurement results are the basis for rate adjustment and link stability control of AMR/AMR-WB services and BE services. By comparing the measurement results, the RNC determines an appropriate control function.

3.1 Link Stability Measurement for AMR/AMR-WB Services

Link stability measurement for AMR/AMR-WB services is performed to trigger link stability control for AMR/AMR-WB services.

3.1.1 Stability Measurement Items for AMR/AMR-WB Services In the UL, the measurement item is the TX power of the UE.

In the DL, the measurement item is the TX power of the DPDCH.

Measurement results are reported through events.

Measurement Item Event

TX power of the UE in the UL 6A1 and 6A2 6B1 and 6B2 6D

TX power of the DPDCH in the DL E1 and E2 F1 and F2

3.1.2 UL Stability Measurement for AMR/AMR-WB Services Measurement results serve as the basis of AMRC/AMRC-WB. By comparing the measurement results with associated thresholds, the UE reports corresponding events. Then, the RNC takes corresponding AMRC/AMRC-WB actions.



UL Measurement Control UL AMRC/AMRC-WB events consist of 6A1, 6A2, 6B1, 6B2, and 6D. These events indicate different states of TX power of the current UE. The RNC adjusts the maximum permissible UL AMR/AMR-WB codec rate according to the reported events.

After establishing an AMR/AMR-WB speech service, the RNC sends the following information to the UE through a MEASUREMENT CONTROL message:

l Threshold of event 6A1, 6B1, 6A2, 6B2, or 6D for TX power l Time to trigger event 6A1, 6B1, 6A2, 6B2, or 6D

Then, the UE measures the TX power in real time, filters the measurement results, and takes corresponding actions:

l If the UE TX power is above the threshold of event 6A1 for TX power for a period of time specified by UlAmrTrigTime6A1, event 6A1 is triggered.

l If the UE TX power is below the threshold of event 6B1 for TX power for a period of time specified by UlAmrTrigTime6B1, event 6B1 is triggered.

l If the UE TX power is below the threshold of event 6B2 for TX power for a period of time specified by UlAmrTrigTime6B2, event 6B2 is triggered.

l If the UE TX power is above the threshold of event 6A2 for TX power for a period of time specified by UlAmrTrigTime6A2, event 6A2 is triggered.

l If the UE TX power is equal to the maximum TX power for a period of time specified by UlAmrTrigTime6D, event 6D is triggered.

Each time a measurement event is triggered, the UE sends a measurement event report to the UTRAN through a MEASUREMENT REPORT message. Then, the UL AMRC/AMRC-WB function performs corresponding control tasks according to the report.

UL Events and Thresholds Events 6A1, 6A2, 6B1, and 6B2 have different thresholds, as shown in Figure 3-3.

Figure 3-1 UL events and thresholds



As shown in Figure 3-1, the maximum UL TX power for conversational services is specified by the parameter MaxUlTxPowerforConv. Delta_6a1, Delta_6b1, Delta_6a2, and Delta_6b2 are relative thresholds, which are the differences between the absolute thresholds of events 6A1, 6B1, 6A2, and 6B2 for TX power and the maximum UL TX power of conversational service. They are specified by the parameters UlThd6A1, UlThd6B1, UlThd6A2, and UlThd6B2 respectively.

The absolute thresholds are calculated according to the following formulas:

l Threshold of event 6A1 for TX power = MaxUlTxPowerforConv – UlThd6A1 l Threshold of event 6B1 for TX power = MaxUlTxPowerforConv – UlThd6B1 l Threshold of event 6A2 for TX power = MaxUlTxPowerforConv – UlThd6A2 l Threshold of event 6B2 for TX power = MaxUlTxPowerforConv – UlThd6B2

The threshold of event 6D is the maximum TX power of the UE.

Figure 3-2 Threshold of event 6D

3.1.3 DL Stability Measurement for AMR/AMR-WB Services Measurement results serve as the basis of AMRC/AMRC-WB. By comparing the measurement results with associated thresholds, the RNC takes corresponding AMRC/AMRC-WB actions.

DL Measurement Control DL AMRC/AMRC-WB events consist of E1, E2, F1, and F2. These events indicate different states of TX power of the current DPDCH. The RNC adjusts the maximum permissible DL AMR/AMR-WB codec rate according to the reported events.

After establishing a service, the RNC requests the NodeB to periodically send measurement reports on the DL transmitted code power (TCP) in the pilot field of the DPCCH. After receiving the request, the NodeB sends the measurement reports on the TCP to the RNC every 480 ms.

After receiving the measurement reports, the RNC converts the measured DL TCP in the pilot field of the DPCCH into the average TX power of the DPDCH. Then, the RNC compares the average DPDCH TX power with the thresholds of events E1, E2, F1, and F2 to determine the type of event.

l When the average TX power of the DPDCH is above the threshold of event E1 for TX power, event E1 is triggered.



l When the average TX power of the DPDCH is below the threshold of event E2 for TX power, event E2 is triggered.

l When the average TX power of the DPDCH is below the threshold of event F1 for TX power, event F1 is triggered.

l When the average TX power of the DPDCH is above the threshold of event F2 for TX power, event F2 is triggered.

DL Events and Thresholds Events E1, E2, F1, and F2 have different thresholds, as shown in Figure 3-3.

Figure 3-3 DL events and thresholds

The maximum DL DPDCH TX power shown in Figure 3-3 is specified by the parameter RlMaxDlPwr. Delta_E1, Delta_E2, Delta_F1, and Delta_F2 are relative thresholds, which are the differences between the absolute thresholds of events E1, E2, F1, and F2 for TX power and the maximum DL DPDCH TX power. They are specified by the parameters DlThdE1, DlThdE2, DlThdF1, and DlThdF2 respectively.

The absolute thresholds are calculated according to the following formulas:

l Threshold of event E1 for TX power = RlMaxDlPwr – DlThdE1 l Threshold of event E2 for TX power = RlMaxDlPwr – DlThdE2 l Threshold of event F1 for TX power = RlMaxDlPwr – DlThdF1 l Threshold of event F2 for TX power = RlMaxDlPwr – DlThdF2



3.2 Link Stability Measurement for BE Services Link stability measurement for BE services is performed to trigger link stability control for BE services.

3.2.1 Link Stability Measurement Items for BE Services UL quality measurement involves two measurement items: UL TX power of the UE and UL BLER.

l The UL TX power of the UE is measured on the Uu interface. If the UL TX power reaches the maximum power, you can infer that the radio link is unstable.

l The UL BLER is measured by the RNC. If the UL BLER is excessively high, you can infer that the radio link is unstable.

DL quality measurement involves two measurement items: TCP and RLC PDU retransmission rate.

l The TX power in the pilot field of the DPCCH is measured on the NodeB side. When the TX power is above the threshold of event Ea, you can infer that the radio link is unstable.

l Whether the RLC PDU retransmission rate needs to be measured can be specified by the parameter SrncBeDlRlcQosSwitch. The RLC PDU retransmission rate is reported by event A. When the RLC PDU retransmission rate is above the threshold of event A, you can infer that the radio link is unstable.

Measurement results are reported by events.

3.2.2 UL Stability Measurement for BE Services

Event 6A/6B/6D According to the measurement result of UE TX power in the UL, event 6A, 6B, or 6D is triggered. For details about triggering modes, see section 3.1.2 "UL Stability Measurement for AMR/AMR-WB Services." The following new triggering time parameters are introduced: UlBeTrigTime6A1, UlBeTrigTime6A2, UlBeTrigTime6B1, UlBeTrigTime6B2, and UlBeTrigTime6D.

Event 5A The UL BLER measurement may trigger event 5A. The RNC defines a sliding window of a certain length through the parameter StaBlkNum5A. Each time the RNC receives a data block, it compares the number of error blocks in the sliding window with the threshold of



event 5A specified by the parameter Thd5A. If the number of error blocks is above or equal to the threshold of event 5A, event 5A is triggered. Then, the RNC can trigger again event 5A only after the number of received error blocks reaches HangBlockNum5A, to avoid excessive reporting of event 5A.

Figure 3-4 shows the mechanism of triggering and reporting event 5A.

Figure 3-4 Mechanism of triggering and reporting event 5A

3.2.3 DL Stability Measurement for BE Services

Event E/F Event E is used to check whether the DL power is excessively high. Event E can trigger a DL rate decrease. Event E consists of event Ea and event Eb. Event F is used to check whether the current TX power allows a rate increase. Event F consists of event Fa and event Fb.

According to the measurement result of DL TX power in the pilot field of the DPCCH, event E or F is triggered as follows:

l If the TX power in the pilot field of the DPCCH is above the threshold of event Ea or Fa for a period of time specified by DlBeTrigTimeE or DlBeTrigTimeF, event Ea or Fa is triggered. Then, the NodeB periodically reports the measurement results of TX power to the RNC. The period for the NodeB to report measurement results is specified by the parameter ChoiceRptUnitForBeE, TenMsecForBeE, or MinForBeE for event E and by the parameter ChoiceRptUnitForBeF, TenMsecForBeF, or MinForBeF for event F.

l If the TX power in the pilot field of the DPCCH is below the threshold of event Eb or Fb for a period of time, event Eb or Fb is triggered. For BE services, this period is set to 640 ms. Then, the NodeB stops reporting the measurement results of TX power.

In RAN 11.0, the thresholds of events Fa and Fb are the same. The threshold of event F cannot be above the threshold of event Ea. Otherwise, the threshold of event F is set to the threshold of event Ea.

The threshold of event E is related to services. The relative threshold of event Ea or Eb is calculated according to the following formula:

E threshold = Maximum DL power – Relative threshold + PO3

In the equation:

l E threshold is the relative threshold of event Ea or Eb.



l PO3 is the offset from the TX power in the pilot field of the DPCCH to the TX power of the DPDCH.

l Relative threshold is the relative threshold of event Ea or Eb, specified by the parameter ThdEa or ThdEb respectively.

l Maximum DL power is the maximum DL TX power of DPDCHs.

The threshold of event F is related to the current rate and the target rate of rate increase (triggered by event 4a). The threshold of event F is calculated according to the following formula:

F threshold = Pmax – ∆p – Pmargin – Ea relative threshold + PO3

In the equation:

l ∆p is the power difference between the current rate and the target rate. l Pmargin is determined by the parameter BePwrMargin for a single service or by the

parameter CombPwrMargin for combined services. l Ea relative threshold is used to avoid repeated triggering of event Ea after a rate increase. l Pmax is the maximum DL TX power corresponding to the target rate. l PO3 is the offset from the TX power in the pilot field of the DPCCH to the TX power of

the DPDCH.

Figure 3-5 shows the mechanism of reporting event F.

Figure 3-5 Mechanism of reporting event F

Event A The DL RLC PDU retransmission rate is calculated according to the ACK or NACK feedback information. The RLC PDU retransmission rate can be set by the parameter SrncBeDlRlcQosSwitch through the SET QOSACT command.

The RLC PDU retransmission rate is reported to layer 3 from layer 2. Figure 3-6 shows the threshold for reporting the RLC PDU retransmission rate.



Figure 3-6 Threshold for reporting the RLC PDU retransmission rate

The procedure for measuring the RLC PDU retransmission rate is as follows:

1. Set up a sliding window for calculating the RLC PDU retransmission rate periodically according to the period of monitoring the retransmission rate specified by the parameter MoniterPrd.

2. Check whether the RLC PDU retransmission rate is above the threshold of event A specified by the parameter EventAThred. If it is above the threshold for a period of time, that is, MoniterPrd x TimeToTiggerA, event A is triggered and the RLC PDU retransmission rate is reported. Event A based on the RLC PDU retransmission rate is defined by Huawei. It is not a standard event specified by 3GPP specifications.

In the period of time (MoniterPrd x TimeToTiggerA) after event A is reported, the RLC PDU retransmission rate is not calculated any more. If a report on event Ea is already received before a report on event A is received, the system may reduce the DL rate.

3.3 Traffic Volume Measurement for BE Services 3.3.1 Traffic Volume Measurement Item for BE Services

In the UL, the UE measures the buffer usage of RLC entities to obtain the UL traffic volume. In the DL, the RNC measures the buffer usage of RLC entities to obtain the DL traffic volume.

The traffic volume measurements defined in 3GPP TS 25.331 are applicable to only the UL. For the DL, traffic volume measurements and associated rate adjustment are designed and implemented by Huawei.



Traffic volume (buffer usage of RLC entities) 4a and 4b



3.3.2 Traffic Volume Measurement Control for BE Services Events 4a and 4b indicate different states of UL and DL traffic volumes. The RNC can increase or decrease service rates according to the reported events. Event 4a indicates that the traffic volume is excessively high, and thus the RNC needs to decrease service rates. Event 4b indicates that the traffic volume is excessively low, and thus the RNC needs to increase service rates.

In the UL, the UTRAN sends to the UE the absolute threshold, time to trigger event 4a or 4b, and pending time after trigger through a MEASUREMENT CONTROL message. The UE sends a report on event 4a or 4b through a MEASUREMENT REPORT message.

In the DL, measurement control is also performed through messages. The difference is that all the interactions occur within the RNC in the DL.

3.3.3 Threshold for Triggering Event 4a or Event 4b For event 4a or 4b in the UL or DL:

l If the traffic volume is above the threshold of event 4a specified by Event4aThd for a period of time specified by TimetoTrigger4A, the UE sends a report on event 4a. In a period of time specified by the parameter PendingTime4A after sending the report on event 4a, the UE does not send it any more.

l If the traffic volume is below the threshold of event 4b specified by Event4bThd for a period of time specified by TimetoTrigger4B, the UE sends a report on event 4b. After sending the report on event 4b, the UE does not send it again in a period of time specified by PendingTime4B.

Rate adjustment based on traffic volume takes effect in the UL and DL separately. Associated parameters are configured in the UL and DL separately. The parameter Direction specifies whether the parameters are configured in the UL or DL.

Figure 3-7 Triggering 4a for an increase in traffic volume



Figure 3-8 Triggering 4b for a decrease in traffic volume

3.4 Throughput Measurement for BE Services DCH and E-DCH BE service rate adjustment is based on throughput measurement results. After comparing the measurement results with associated thresholds, the RNC decides whether to trigger rate adjustment.

3.4.1 Throughput Measurement Item for BE Services In each measurement period, the MAC-d measures the traffic volume of radio bearers (RBs). Then, it divides the measurement result by the measurement period to obtain the throughput.

The throughput measurement period can be specified by the parameter E2FThrouMeasPeriod for services on the E-DCH and DchThrouMeasPeriod for services on the DCH.



Throughput (traffic volume of RBs measured by the MAC-d in a measurement period)

4a and 4b

3.4.2 Throughput Measurement Control for BE Services Assume that AvgThroughput represents the throughput of an RB during a measurement period. Then:

l If the AvgThroughput is above the threshold of event 4a for a period of time specified by EdchTimetoTrigger4A and the current time is not in the pending time after trigger, then event 4a is triggered. After event 4a is triggered, it cannot be triggered any more in the period of time specified by EdchPendingTime4A.



l If the AvgThroughput is below the threshold of event 4b for a period of time specified by EdchTimetoTrigger4B or DchThrouTimetoTrigger4B and the current time is not in the pending time after trigger, then event 4b is triggered. After event 4b is triggered, it cannot be triggered any more in the period of time specified by EdchPendingTime4B or DchThrouPendingTime4B.

Figure 3-9 shows the mechanism of measuring the throughput and reporting events 4a and 4b. In this example, the time to trigger event 4a or 4b is three consecutive measurement periods, and the pending time after trigger is four consecutive measurement periods.

Initial access rate of AMR services

The RNC assigns the initial access rate to AMR services according to the cell load. The initial access rate is the maximum rate in the entire process of AMR services.

AMRC based on link stability

The RNC adjusts the UL rate of AMR services according to the UE TX power to ensure the UL stability. The RNC adjusts the DL rate of AMR services according to the DPDCH TX power to ensure the DL stability. For details, see section 4.1.3 "AMRC/AMRC-WB Based on Link Stability."

AMRC based on basic congestion

In the basic congestion state, the RNC decreases the rate of AMR services to reduce the cell load. For details, see section 4.1.4 "AMRC/AMRC-WB Rate Adjustment Based on Basic Congestion."

Table 4-2 defines the key terms involved in AMRC/AMRC-WB.

Table 4-2 Key terms involved in AMRC/AMRC-WB

Term Definition

GBR The guaranteed bit rate (GBR) is the minimum rate to ensure the normal operation of user services. It is also the minimum rate permitted in rate adjustment by the RNC. It is carried in the RAB assignment message that the CN sends to the RNC.



Term Definition

MBR The maximum bit rate (MBR) is the maximum rate of user services. It is also the maximum rate permitted in rate adjustment by the RNC.

Supported rate set

This set consists of all the AMR codec rates that can be used for service transport.

Controllable rate set

This set consists of the AMR codec rates that are contained in the supported rate set and are higher than or equal to the GBR. The rates in this set can be selected by the AMRC/AMRC-WB function for rate adjustment.

For example: Assume that the supported rate set is {0, SID, 4.75 kbit/s, 7.95 kbit/s, 12.2 kbit/s} and the GBR is 4.75 kbit/s. Then, the controllable rate set is {4.75 kbit/s, 7.95 kbit/s, 12.2 kbit/s}. SID stands for Silence Indicator. It can be used to maintain a session when there is no data.

Initial Access Rate In the UL, the initial access rate is not only the maximum permissible rate in the initial communication phase, but also the maximum rate that the UL AMRC/AMRC-WB function can select. It is equal to the maximum rate in the UL controllable rate set and UL supported rate set. In the DL, the initial access rate is the maximum permissible rate in the initial communication phase.

The RNC selects the initial access rate from the rate set listed in the RAB assignment message. The initial access rate is represented by IBR, which stands for Initial Bit Rate. The maximum initial access rate is the maximum rate in the rate set in the RAB assignment message. It cannot be higher than the maximum rate of user priority-based services (it can be configured through the LMT). The maximum initial access rate is represented by Rmax. The minimum initial access rate cannot be lower than the GBR.

When the AMRC/AMRC-WB function is enabled,

l If the cell load is normal, then IBR = max{GBR, Rmax}. l If the cell is in the basic congestion state, then IBR = GBR. For details about basic

congestion, see the Load Control Parameter Description.

When the AMRC/AMRC-WB function is disabled, IBR = max{GBR, Rmax}.

l For AMRC and AMRC-WB, the maximum rate of user priority-based services can be set through the

ADD CELLAMRC and ADD CELLAMRCWB commands. For details about the user priority, see the Load Control Parameter Description.

l If the maximum rate of user priority-based services is lower than the GBR, the initial access rate is set to the GBR.

l This NOTE is applicable to all the initial access rates used in AMRC and AMRC-WB that are mentioned in this document.

Controllable AMR/AMR-WB Rate Set The controllable AMR/AMR-WB rate set is valid only when the AMRC/AMRC-WB function is enabled. Table 4-3 lists the controllable AMR/AMR-WB rate set.

The DL code-resource-saving function is available only for the RNC. If the maximum DL rate of a single speech service is lower than or equal to 7.95 kbit/s, this function allows this service to use Spreading Factor (SF) 256 in the DL. If the DL code-resource-saving function is disabled, only SF 128 can be used in the DL.

4.1.2 AMRC/AMRC-WB Switch The AMRC/AMRC-WB function is controlled by the subparameter CS_AMRC_SWITCH of the parameter CsSwitch.

4.1.3 AMRC/AMRC-WB Based on Link Stability

UL Rate Adjustment The UL AMRC/AMRC-WB function adjusts the maximum permissible UL AMR/AMR-WB codec rate based on the TX power of the UE to ensure the UL stability.

The UL AMRC/AMRC-WB function performs corresponding control tasks according to measurement reports. This function can adjust the maximum permissible UL AMR/AMR-WB codec rate in the controllable rate set by only one level each time.

The detailed process is as follows:



l If the report on event 6A1 or 6D is received, the maximum permissible UL AMR/AMR-WB codec rate is decreased. Rate decrease is performed continually until the report on event 6B1 or 6B2 is received. If the rate is the GBR before the rate decrease or if the rate decrease fails, a soft handover is performed.

l If the report on event 6B2 is received and the UL load is normal, the maximum permissible AMR/AMR-WB codec rate is increased. Rate increase is performed continually until the report on event 6A2 or 6A1 is received. If the rate is already the maximum rate in the controllable rate set before rate increase, rate increase is not performed.

After each adjustment, the UL rate adjustment waiting timer for AMR/AMR-WB service is started to avoid frequent adjustment. The timer is specified by the parameter AmrUlRateAdjTimerLen/ WAmrUlRateAdjTimerLen. Rates involved in rate decrease and rate increase must be within the controllable rate set.

DL Rate Adjustment The DL AMRC/AMRC-WB function adjusts the maximum permissible DL AMR/AMR-WB codec rate in the controllable rate set based on the TX power of the DPDCH. This function can adjust the rate by only one level each time.

The detailed process is as follows:

l If the report on event E1 is received, the maximum permissible DL AMR/AMR-WB codec rate is decreased. Rate decrease is performed continually until the power is below the threshold of event E2. If the rate is the GBR before the rate decrease or if the rate decrease fails, a soft handover is performed.

l If the report on event F1 is received and the DL load is normal, the maximum permissible AMR/AMR-WB codec rate is increased. Rate increase is performed continually until the power is above the threshold of event F2. If the rate is already the maximum rate in the controllable rate set before rate increase, rate increase is not performed.

4.1.4 AMRC/AMRC-WB Rate Adjustment Based on Basic Congestion

AMRC/AMRC-WB based on basic congestion is one task of Load Reshuffling (LDR). For details about the LDR function, see the Load Control Parameter Description.

When the cell enters the basic congestion state, the LDR function performs corresponding tasks to reduce the cell load. When the cell exits from the basic congestion state, the LDR function does not perform any task on the UEs in the cell. When the network is congested, the RNC does not perform rate increase.

When the cell enters the basic congestion state in the UL or DL and the AMR/AMR-WB rate decrease is triggered, the maximum permissible UL or DL AMR/AMR-WB codec rate is decreased to the GBR in the UL or DL controllable rate set.

4.2 DCCC 4.2.1 Overview of DCCC

DCCC is mainly used to control the rate of BE services on the DCH.



Table 4-4 lists the functions of DCCC.

Table 4-4 Functions of DCCC

DCCC Based on Traffic Volume

The traffic volume is measured by the buffer usage of the RLC entity. The RNC increases or decreases the rate of BE services based on the traffic volume to avoid excessively high or low traffic volume. For details, see section 4.2.3 "DCCC Based on Traffic Volume."

DCCC Based on Throughput

Throughput is the traffic volume in a measurement period. The RNC adjusts the rate of BE services based on the throughput. For HSUPA BE services, the RNC performs rate decrease or rate increase based on the throughput. For DCH BE services, the RNC performs rate decrease only when the throughput is excessively high. For details, see section 4.2.4 "DCCC Based on Throughput."

DCCC Based on Link Stability

Rate adjustment based on link stability is applicable to only R99 BE services. Link quality is measured through the UE TX power or BLER in the UL or through the TCP or RLC PDU retransmission rate in the DL. The RNC performs rate decrease or rate increase for R99 BE services based on the link quality. For details, see section 4.2.5 "DCCC Based on Link Stability."

DCCC Based on Basic Congestion

When the cell enters the basic congestion state, the RNC decreases the rate of BE services. When the cell exits from the basic congestion state, the RNC increases the rate of BE services through the DCCC function. For details, see section 4.2.6 "DCCC Based on Basic Congestion."

4.2.2 DCCC Switch The DCCC function is controlled by the subparameter DRA_DCCC_SWITCH of the parameter DraSwitch.

The UL DCCC function is invalid for the BE service whose maximum UL rate is below or equal to the UL rate threshold for DCCC specified by UlDcccRateThd. Thus, excessive signaling procedures can be avoided. The DL rate is limited in the same way. The DL rate threshold is specified by DlDcccRateThd.

HSUPA DCCC and HSUPA dynamic CE resource management cannot be used simultaneously. For details about HSUPA dynamic CE resource management, see the HSUPA Parameter Description.

l If all the cells in the active set support HSUPA dynamic CE resource management, the BE service rate is adjusted to the MBR (the rate need not be adjusted if the current rate is already the MBR), and HSUPA DCCC is invalid.

l If any cell in the active set does not support HSUPA dynamic CE resource management, HSUPA DCCC is valid.

For DCCC of E-DCH BE services and DCCC rate adjustment of DCH BE services, two strategies are available, which can be specified by the parameter DcccStg or HsupaDcccStg:



l The rate can be either increased or decreased as required. l The rate can only be increased and not be decreased. This strategy is recommended if the

network resources are sufficient. When the UE is in the low active state, the UE state is changed to CELL_FACH.

4.2.3 DCCC Based on Traffic Volume The prerequisites for UL rate adjustment based on traffic volume are as follows:

l If the function of UL rate adjustment based on link quality is enabled, the UL power must be very strong. For details, see section 4.2.5 "DCCC Based on Link Stability."

l The cell is not in the basic congestion state in the UL. If the cell is in the basic congestion state in the UL, only the service rate lower than the GBR can be increased to the GBR.

The prerequisites for DL rate adjustment based on traffic volume are as follows:

l If the function of DL rate adjustment based on link quality is enabled, the DL power must be very strong, which can be determined according to event F.

l The cell is not in the basic congestion state in the DL. If the cell is in the basic congestion state in the UL, only the service rate lower than the GBR can be increased to the GBR.

After receiving a report on event 4b, the RNC triggers rate decrease. After receiving a report on event 4a, the RNC triggers rate increase. The minimum value to which the rate can be decreased is the UL rate threshold for DCCC. The maximum value to which the rate can be increased is the MBR.

The triggering and processing in the UL and DL are performed separately. Rate increase and rate decrease are performed in the following conditions. If RATE_UP_ONLY_ON_DCH (the rate on the DCH is increased but not decreased) is used, rate decrease is ignored.

l If the UL rate decrease level is 2_Rates, the rate is decreased directly to the UL rate threshold for DCCC.

l If the UL rate increase level is 2_Rates and the current rate is below the UL DCCC rate threshold, the current rate is increased to the UL DCCC rate threshold. If the current rate is above or equal to the UL rate threshold for DCCC and lower than the MBR, the current rate is increased to the MBR.

l If the UL rate decrease level is 3_Rates and the current rate is the MBR, the current rate is decreased to the UL middle rate threshold and then to the UL rate threshold for DCCC. If the current rate is lower than the MBR but higher than the UL rate threshold for DCCC, the current rate is decreased to the UL rate threshold for DCCC.

l If the UL rate increase level is 3_Rates and the current rate is below the UL DCCC rate threshold, the rate is increased to the UL rate threshold for DCCC. If the current rate is equal to the UL rate threshold for DCCC, the current rate is increased to the UL middle rate threshold and then to the MBR. If the current rate is lower than the MBR but higher than the UL rate threshold for DCCC, the current rate is increased to the MBR.

Table 4-5 lists the configuration items used in rate adjustment based on traffic volume.

Specified by the parameter UlDcccRateThd.

DL rate threshold for DCCC

Specified by the parameter DlDcccRateThd.

Figure 4-1 Rate adjustment when the UL rate increase and decrease level are 3_Rates



4.2.4 DCCC Based on Throughput This section describes the procedure of BE service rate adjustment based on throughput.

The switches for rate adjustment based on throughput are as follows:

l To enable throughput-based rate adjustment on the DCH, set the subparameter THROU_DCCC_SWITCH of the parameter CfgSwitch to ON through the SET CORRMALGOSWITCH command.

l To enable throughput-based rate adjustment for HSUPA, set the subparameter DRA_HSUPA_DCCC_SWITCH of the parameter DraSwitch to ON through the SET CORRMALGOSWITCH command.

For the DCH and E-DCH, the strategies for rate adjustment based on throughput are different.

l For throughput-based rate adjustment on the E-DCH, rate increase or decrease can be triggered according to the received event 4a or 4b respectively.

l For throughput-based rate adjustment on the DCH, only rate decrease can be performed according to the received event 4b.

Except that rate increase cannot be performed on the DCH, the rate adjustment procedures on the E-DCH and DCH are the same.

l After a report on event 4a is received, the rate is increased by one level, that is, from Rt to Rt+1. If the current rate is the MBR, no action is required.

l After a report on event 4b is received, the rate is decreased to a rate that is close to the corresponding throughput. If the reported throughput is TR and TRi-1 <TR < TRi, then the RB adjustment rate is Ri.

Figure 4-2 Average throughput between TRi–1 and TRi

If the rate adjustment strategy is only rate increase rather than rate decrease, the rate adjustment method is the same as that mentioned earlier, but rate decrease is not performed after the report on event 4b is received.

4.2.5 DCCC Based on Link Stability Rate adjustment based on link stability is applicable to BE services on the DCH.

After an event indicating that the link quality is poor is reported, the RNC triggers rate decrease. When the associated conditions are met, the RNC adjusts the service rate to the original one. The rate adjustment methods in the UL and DL are the same. The adjustment processes are performed separately.



Rate Decrease Rate decrease based on link quality is performed in the following way with the adjustment level to be 3_Rates:

l If the current rate is equal to the MBR, it is decreased to the middle rate threshold specified by UlMidRateThd or DlMidRateThd.

l If the current rate is higher than the full-coverage rate specified by UlFullCvrRate or DlFullCvrRate but lower than the MBR, it is decreased to UlFullCvrRate or DlFullCvrRate.

The middle rate threshold is the same as that described in section 4.2.3 "DCCC Based on Traffic Volume." If the rate decrease level (UlRateDnAdjLeve or DlRateDnAdjLevel) is set to 2_Rates, the middle rate for rate adjustment based on link quality is approximately equal to the MBR divided by two. This middle rate is calculated by the RNC.

Figure 4-3 Rate adjustment based on link quality when the adjustment level is 3_Rates

Rate Increase Before rate increase, the RNC checks whether the current power is sufficient. If the power is sufficient, rate increase is triggered by event 4a.

In the UL:

l If the RNC receives a report on event 6B2 but does not receive any report on event 6A2, the channel power is sufficient. In this case, rate increase based on traffic volume can be triggered by event 4a.

l If the RNC receives a report on event 6A2, no rate increase based on traffic volume can be triggered by event 4a. If the RNC receives a report on event 6B1, rate decrease is stopped and no rate increase can be triggered.



In the DL:

l If event Fa is reported, you can infer that the DL channel power is sufficient. If event 4a is also reported, a rate increase can be triggered.

l If event Fb is reported, you can infer that the DL channel power is insufficient. In this case, no rate increase can be triggered.

For details about the reporting of event 4a and the procedure of rate increase, see section 3.3 "Traffic Volume Measurement for BE Services."

4.2.6 DCCC Based on Basic Congestion Basic congestion may trigger LDR, and LDR can reduce load by reducing the rate of BE services. For details about LDR, see the Load Control Parameter Description.

When the cell enters the basic congestion state, the maximum target rate is the GBR for a BE RAB. When the cell exits from the basic congestion state, the LDR function does not perform any task on the UEs in the cell. The system decreases or increases service rates through the DCCC function.

Rate Adjustment Based on Basic Congestion When LDR triggers BE service rate decrease, the selected RAB rate is decreased to the target rate. The target rates for rate adjustment are different for DCH RAB and HSUPA RAB.

l If the selected RAB is a DCH RAB, the rate adjustment level can only be 3_Rates. − If the current rate is equal to the MBR, it is decreased to the UL middle rate threshold

(UlMidRateThd). − If the current rate is higher than the GBR but lower than the MBR, it is decreased to the

GBR.

The middle rate threshold is the same as that described in section 4.2.3 "DCCC Based on Traffic Volume." If the UL rate adjustment level (UlRateDnAdjLevel) is 2_Rates, the UL middle rate is approximately equal to the MBR divided by two. This middle rate is calculated by the RNC.

l If the selected RAB is an HSUPA RAB, a rate is selected from the HSUPA UL rate adjustment set (EdchRateAdjustSet) as the target rate for rate decrease. The selected rate must be smaller than but the closest to the current rate. The target rate must be greater than or equal to the GBR. For details about the HSUPA UL rate adjustment set (EdchRateAdjustSet), see section 3.4 "Throughput Measurement for BE Services."

Figure 4-4 shows an example of UL BE rate decrease and increase, in which the RAB is a DCH RAB. In this example, the UL rate decrease level is 3_Rates, a rate decrease is triggered by UL basic congestion, and a rate increase is triggered when basic congestion is relieved. In addition, the current UL rate can be the initial rate, middle rate, or MBR.

When the current rate is the MBR, it is decreased to the middle rate if a basic congestion report is received, and then decreased to the GBR if a second basic congestion report is received.



Figure 4-4 BE rate decrease and increase based on UL basic congestion

Rate Increase Failure and Penalty A rate increase failure may be due to lack of Iub resources, lack of cell resources, NodeB exception, UE exception, or other causes. If rate increase failures occur frequently, rate increase attempts have to be prevented for a period of time.

Figure 4-5 shows the procedure for penalizing rate increase failures when the adjustment level is 2_Rates.



Figure 4-5 Rate increase failure penalty in the case of 2_Rates adjustment

The symbols in Figure 4-5 are described as follows:

l 1–8: indicating that event 4a is reported from the UE l S1: indicating that the cell is in the normal state l S2: indicating that the cell is in the congestion state l S3: indicating that the cell is restored from the congestion state

The procedure for penalizing rate increase failures is as follows:

Step 1 After the first rate increase fails, the timer for detecting DCCC rate increase failures is started. The timer length is specified by the parameter MoniTimeLen. Each time the rate increase fails, the rate increase failure counter is incremented by one.

Step 2 The rate increase failure counter determines whether to start the timer for penalizing DCCC rate increase failures:

l Before the timer for detecting DCCC rate increase failures expires, the penalty timer is started if the number of such failures is above or equal to the corresponding threshold (FailTimeTh). No rate increase attempt is allowed before the penalty timer expires.

l When the timer for detecting DCCC rate increase failures expires, the rate increase failure counter returns to 0 and the system returns to step 1 if the number of rate increase failures is below the corresponding threshold.

Step 3 Rate increase attempts are allowed after the penalty timer expires. If a rate increase attempt is repeated when the cell is in the congestion state, the system returns to step 1.



l The timers for detecting DCCC rate increase failures in the UL and DL work independently. l When the cell is in the basic congestion state, the rates lower than the GBR can be increased.

Whether rate increase can succeed depends on whether the required resources are sufficient.

RAN Rate Control 5 Parameters


5 Parameters

This describes the parameters related to rate control.

For the meaning of each parameter, see Table 5-1. For the default value, value ranges, and MML commands of each parameter, see Table 5-2.

Table 5-1 Rate control parameter description (1)

Parameter ID Description

AmrUlRateAdjTimerLen Timer for triggering a second adjustment of the UL AMR mode. This parameter specifies the duration of waiting for the voice quality enhanced acknowledgement after the UL AMR mode adjustment when the associated command is delivered. The UL AMRC rate adjust timer starts when AMRC mode adjustment procedure is triggered, and stops when the next measurement report is received. If no measurement report is received when the UL AMRC timer expires, you can infer that the measured value remains in the same state as that before the previous UL AMRC mode adjustment. The previous AMRC mode adjustment is not effective, and another adjustment is required. The longer the UL AMRC timer is, the less frequently the AMRC mode is adjusted. In addition, the response to measurement reports becomes slower accordingly.

BeDlAct1 The first action selected by the QoS control algorithm when the DL QoS of BE service deteriorates.If QoS action is RateDegrade, then the rate will be downsized to the full coverage rate according to 3-rates rule.

BeDlAct2 The second action selected by the QoS control algorithm when the DL QoS of BE service deteriorates.If QoS action is RateDegrade, then the rate will be downsized to the full coverage rate according to 3-rates rule.

BeDlAct3 The third action selected by the QoS control algorithm when the DL QoS of BE service deteriorates.If QoS action is RateDegrade, then the rate will be downsized to the full coverage rate according to 3-rates rule.

BeE2FStateTransTimer Timer for state transition from E-DCH to FACH of BE services, used to check whether the UE with BE services carried over the E-DCH is in the stable low activity state. If the value of this parameter is too low, whether the UE is in the stable low activity state cannot be determined. If the value of this parameter is too high, the dedicated channel resources are wasted. This parameter should be set on the basis of the BE service model.




BeH2FStateTransTimer Timer for state transition from HS-DSCH to FACH of BE services, used to check whether the UE in the CELL_DCH(with HS-DSCH) state with BE services is in the stable low activity state. If the value of this parameter is too low, whether the UE is in the stable low activity state cannot be determined. If the value of this parameter is too high, the dedicated channel resources are wasted. This parameter should be set on the basis of the BE service model.

BeH2FTvmPTAT Pending time after the traffic volume event 4b is reported. This parameter is used to prevent too many traffic volume events 4b being reported.

BeH2FTvmThd This parameter is used to check whether the UE in the low activity state. If the UE is in the CELL_DCH (with HS-DSCH) state, the low activity counter increases by 1 every time traffic volume event 4b is reported.

BeH2FTvmTimeToTrig When the traffic volume is below the lower threshold and remains so for the period specified by this parameter, the event 4b is reported. This parameter prevents unnecessary traffic volume events that are caused by traffic volume instability from being triggered.

BePwrMargin The ralative power margin of single BE traffic, used to calculate the triggering threshold of event F, can avoid the fluctuation of traffic rate in case the power becomes restricted after rate is increased.

BeUlAct1 The first action selected by the QoS control algorithm when the UL QoS of BE service deteriorates.If QoS action is RateDegrade, then the rate will be downsized to the full coverage rate according to 3-rates rule.

BeUlAct2 The second action selected by the QoS control algorithm when the UL QoS of BE service deteriorates.If QoS action is RateDegrade, then the rate will be downsized to the full coverage rate according to 3-rates rule.

BeUlAct3 The third action selected by the QoS control algorithm when the UL QoS of BE service deteriorates.If QoS action is RateDegrade, then the rate will be downsized to the full coverage rate according to 3-rates rule.

BeUlEvTrigInd For BE service, When the parameter is set to SINGLE, an UL event 6A1 or 5A can independently trigger the QOS enhancement action. The 6A1, 5A switch settings decide whether to perform 6A1 or 5A measurement control. When the parameter is set to COMBINE, only combined events 6A1+5A can trigger the QOS enhancement action, and whether to perform 6A1 and 5A measurement is not controlled by the 6A1 and 5A measurement switch.

BeUlQos5AMcSwitch Event 5A measurement switch when BeUlEvTrigInd is set to SINGLE for BE service. If this parameter is set to YES, event 5A measurement is delivered.

BeUlQos6A1McSwitch Event 6A1 measurement switch when BeUlEvTrigInd is set to SINGLE for BE service. If this parameter is set to YES, event 6A1 measurement is delivered.

BeUlQos6DMcSwitch UL event 6D measurement switch for BE service. If this parameter is set to YES, event 6D measurement is delivered.

BeUlRateAdjTimerLen Timer to trigger the next QoS enhancement action for UL BE services. This parameter specifies the duration of waiting for the UL QoS enhanced acknowledgement after UL rate adjustment. The timer starts when the BE UL rate adjustment procedure is triggered, and stops when the RNC receives a 6B1/6B2 event or when the timer expires.




CellReSelectTimer Length of the cell reselection frequency timer. This parameter is used together with CellReSelectCounter to detect the frequency of cell reselection of the UE in the CELL_PCH state.

CombPwrMargin The ralative power margin of combined traffics, used to calculate the triggering threshold of event F, can avoid the fluctuation of traffic rate in case the power becomes restricted after rate is increased.

CopperMaxMode Maximum rate of the wideband AMR speech service for copper users.

CopperMaxMode Maximum rate of the narrowband AMR speech service for copper users.

CsSwitch CS algorithm switch. 1) CS_AMRC_SWITCH: When the switch is on and the AMRC license is activated, the AMR control function is enabled for AMR services. 2) CS_HANDOVER_TO_UTRAN_DEFAULT_CFG_SWITCH: When the switch is on, the default configurations of signaling and RABs, which are stipulated in 3GPP 25.331, are used for relocation of the UE from GSM to WCDMA. When the switch is not on, the default configurations are not used. Instead, the complete information of RB, TrCH, and PhyCH, which are in the HANDOVER TO UTRAN COMMAND message is used. 3) CS_IUUP_V2_SUPPORT_SWITCH: When the switch is on and the "Support IUUP Version 2" license is activated, the RNC supports the TFO/TRFO function. 4) CS_ZERO_C_AMR_CFG_TWO_CODCH_SWITCH: When the switch is on, the AMR speech service at a maximum rate of 7.95 kbit/s is carried over two DCHs. When the switch is not on, the narrowband AMR speech service at a maximum rate of 7.95 kbit/s is carried over three DCHs.

D2F2PTvmThd This parameter is used to check whether the UE in the low activity state. If the UE is in the CELL_DCH state, the low activity counter increases by 1 every time traffic volume event 4b is reported. If the UE is in the CELL_FACH state, the low activity counter increases by 1 if the traffic volume is 0 in the traffic volume event 4b report.

D2FTvmPTAT Pending time after the traffic volume event 4b is reported. This parameter is used to prevent too many traffic volume events 4b being reported.

D2FTvmTimeToTrig When the traffic volume is below the lower threshold and remains so for the period specified by this parameter, the event 4b is reported. This parameter prevents unnecessary traffic volume events that are caused by traffic volume instability from being triggered.




DcccStg Strategy for adjustment of the rate of the PS BE service when the UE is in the CELL_DCH state. RATE_UP_AND_DOWN_ON_DCH indicates that the rate over the DCH can be raised or lowered. RATE_UP_ONLY indicates that the rate over the DCH can only be raised, which means that the UE can switch to the FACH state at any rate.

DchThrouMeasPeriod This parameter specifies the period of DCH throughput ratio measurement.Macd performs statistic of traffic volume on DCH and reports 4B events which are used for the rate decrease process of BE service set up on DCH.
