Call Admission Control 2 Overview of Call Admission Control



2-1

2 Overview of Call Admission Control

2.1 CAC Policy

Call Admission Control (CAC) is used to determine whether the system resources in a cell are sufficientto accept a resource request. If the system resources are sufficient, the resource request is accepted;otherwise, the resource request is rejected.

A radio link sends a resource request to the CAC functional module when additional resources arerequired, in cases such as radio resource control (RRC) connection setup, new service setup, change ofexisting services, soft handover, and cell change. Upon receiving a resource request, the CAC functionalmodule determines whether the request can be accepted by measuring the cell load and the requestedresources. For details about measuring the cell load, see theLoad Control Feature ParameterDescription.

The admission decision performed using CAC is based on the following resources: NodeB creditresources, Iub resources, code resources, and power resources. In the case of an HSPA resource

request, the admission decision is also based on the number of HSPA users. The admission succeedsonly when the resources on which CAC is based are available.

With CAC, an overloaded cell can accept resource requests for an RRC connection setup only in thecase of emergency calls, detachments, or registrations. This is because the priority of such requests ishigh. This helps maintain system stability when cells are overloaded. In addition, admitting or rejectingusers over FACH or enhanced FACH channels (HS-DSCH) in an overloaded cell can be specified bysetting FACH_UU_ADCTRLof theNBMCacAlgoSwitchparameter.

2.2 CAC Procedure

A radio link sends a resource request to the CAC functional module when additional resources arerequired. On receipt of the resource request, the CAC functional module performs the admissiondecision based on the following resources:

1. NodeB credit resources, which are used to measure the channel demodulation capability of NodeBs

2. Available Iub transmission bandwidth

3. Available cell code resources

4. Number of HSPA users:

Number of HSDPA users (only for HSDPA services)

Number of HSUPA users (only for HSUPA services)

5. Available cell power resources

A call can be admitted only when all of these resources are available.

Code resource-based and Iub resource-based admission control are mandatory and cannot be disabled.For HSDPA/HSUPA services, admission control based on the number of HSUPA/HSDPA users is alsomandatory. Other admission control policies are enabled or disabled by running the MODUCELLALGOSWITCHor SET UCACALGOSWITCH command.

Figure 2-1 shows the basic procedure for a resource-based admission decision.

Call Admission Control 3 CAC Based on NodeB Credit Resources



3-1

3 CAC Based on NodeB Credit Resources

NodeB credit resource-based CAC applies to R99, HSDPA, and HSUPA services in the uplink anddownlink.

3.1 NodeB Credit Resources

The NodeB credit resource is an RNC-related concept. It is referred to as the channel element (CE) onthe NodeB side, indicating the channel demodulation capability of a NodeB.

New services can be admitted only when there are sufficient NodeB credit resources on the RNC sideand sufficient CE resources on the NodeB side.

CEs are classified into uplink and downlink CEs:

An uplink 12.2 kbit/s voice service (SF = 64) plus 3.4 kbit/s signaling traffic consume one uplink CE.

A downlink 12.2 kbit/s voice service (SF = 128) plus 3.4 kbit/s signaling traffic consume one downlink

CE.If only 3.4 kbit/s signaling traffic is carried on a DCH or HSPA channel, one CE is still needed. CEs havebeen reserved for common and HSDPA-related channels. For details about CEs and CE consumption ofdifferent types of service, see theCE Resource Management Feature Parameter Description.

3.2 Admission on RNC

3.2.1 Calculation of the Remaining NodeB Credit Resources on theRNC Side

CE Capability Reporting

NodeB credit resource-based admission is implemented at NodeB level, local cell group (LCG) level (ifany), and local cell (LC) level. Cells in an LCG share the CEs of the LCG in the uplink. The NodeB sendsthe RNC an audit response message, reporting the CE capability of the three levels. The NodeBconsiders physical and licensed CEs when reporting the CE capability to the RNC.

The NodeB-level CEs are the licensed CEs supported by the NodeB.

In the uplink, the number of LCG-level CEs are the smaller one between the number of LCG-levelphysical CEs and the number of NodeB-level licensed CEs. In the downlink, the number of LCG-levelCEs are the sum of downlink CEs on all boards of the LCG.

In the uplink, the LC-level CEs are the physical CEs of the uplink resource group to which the cellbelongs. In the downlink, the LC-level CEs are the physical CEs of the baseband processing board towhich the cell belongs.

Relationship between NodeB Credit Resources and CEs

The relationship between NodeB credit resources and CEs is as follows:

In the uplink, the quantity of NodeB credit resources is twice that of CEs.

In the downlink, the quantity of NodeB credit resources equals that of CEs.

Remaining NodeB Credit Resources

The RNC calculates the remaining NodeB credit resources based on the reported CE capability,relationship between NodeB credit resources and CEs, and the CE consumption rule.

3-2

The RNC implements NodeB credit resource-based admission control based on the calculation result.Uplink and downlink CEs are independent from each other. Therefore, NodeB credit resource-basedadmission is implemented separately in the uplink and downlink.

3.2.2 Admission Decisions on RRC Connection Setup Requests

For an RRC connection setup request, NodeB credit resource-based admission is implemented asfollows:

If theRRCCeCodeCacChoiceparameter is set to LOOSE_CAC, NodeB credit resource-basedadmission succeeds if the available credit resources of the local cell, local cell group (if any), andNodeB are sufficient for setting up an RRC connection.

If theRRCCeCodeCacChoiceparameter is set to STRICT_CAC, the RNC implements NodeB creditresource-based admission based on the cause carried in the RRC connection setup request:

If the cause is "Emergency Call" or "Detach", NodeB credit resource-based admission succeeds ifthe available credit resources are sufficient.

For any other cause, the RNC must ensure that the available credit resources of the local cell, localcell group (if any), and NodeB exceed the reserved credit resources upon admitting an RRCconnection setup request. The reserved credit resources are calculated using SF which is specifiedby the parameterDlRRCCeCodeResvSf(for the downlink) orUlRRCCeResvSf(for the uplink).

3.2.3 Admission Decisions on Other Resource Requests

Handover Service Requests

For a handover service request, NodeB credit resource-based admission succeeds if the available creditresources of the local cell, local cell group (if any), and NodeB are sufficient for the service to beadmitted.

PS Service/CS Service (Non-AMR Service) RequestsFor PS or CS service (non-AMR service) requests, the RNC must ensure that the available creditresources of the local cell, local cell group (if any), and NodeB exceed the reserved credit resourcesupon admitting a new service.

The reserved credit resources are calculated using SF which is specified by theUlHoCeResvSf(for theuplink) orDlHoCeCodeResvSf(for the downlink) parameter.

AMR Service Requests

For AMR service requests,

If theCSRABCacOptSwitchparameter is set to ON, the credit resource-based admission is

successful if the current available credit resources of the local cell, local cell group (if any) and NodeBare sufficient for the service.

If theCSRABCacOptSwitchparameter is set to OFF, the RNC has to ensure that the currentavailable credit of the local cell, local cell group (if any) and NodeB exceeds the reserved credit afteradmitting a new service. The reserved credit is calculated through SF which is determined by theUlHoCeResvSf(for the uplink) orDlHoCeCodeResvSf(for the downlink) parameter.

3.3 Admission on NodeB

NodeB credit resource-based CAC on the NodeB side is not switch controlled and it admits new servicesat the following levels:

5 CAC Based on Code Resources

Code resource-based admission is mandatory when a non-HSDPA service attempts to access thenetwork.

The reserved code resources are shared by all HSDPA services and therefore code resource-based admission control forHSDPA services is not required. For details about code allocation for HSDPA services, see theHSDPA Feature ParameterDescription.

In code resource-based admission, the admission criteria vary with the service request.

RRC Connection Setup Requests

For an RRC connection setup request, code resource-based admission is implemented as follows:

If theRRCCeCodeCacChoiceparameter is set to LOOSE_CAC, code resource-based admissionsucceeds if the remaining code resources are sufficient for setting up an RRC connection.

If theRRCCeCodeCacChoiceparameter is set to STRICT_CAC, the RNC implements coderesource-based admission based on the cause carried in the RRC connection setup request:

If the cause is "Emergency Call" or "Detach", code resource-based admission succeeds if the currentremaining code resources are sufficient.

For any other cause, the RNC must ensure that the current remaining code resources are greaterthan the reserved code resource and the code resource for the RRC connection. The reserved coderesource is specified by theDlRRCCeCodeResvSfparameter.

Handover Service Requests

For handover service requests, code resource-based admission succeeds if the current remaining coderesources are sufficient for the service to be admitted.

PS Service/CS Service (Non-AMR Service) Requests

For PS services/CS service (non-AMR service) requests, the RNC must ensure that the currentremaining code resources are greater than the reserved resource plus the resource for the new service.The reserved resource is specified by theDlHoCeCodeResvSfparameter.

AMR Service Requests

For AMR service requests,

If theCSRABCacOptSwitchparameter is set to OFF, the RNC must ensure that the currentremaining code resources are greater than the reserved resource plus the resource for the new

service. The reserved resource is specified by theDlHoCeCodeResvSfparameter. If theCSRABCacOptSwitchparameter is set to ON, code resource-based admission succeeds if the

current remaining code resources are sufficient for the service to be admitted.

6 CAC Based on the Number of HSPA Users

6.1 CAC for HSDPA Users

HSDPA admission control is based on the number of HSDPA users.

When a new HSDPA service attempts to access the network, the admission based on the number ofHSPA users succeeds if the following conditions are met:

The number of HSDPA users in the cell does not exceed the maximum value specified by theMaxHsdpaUserNumparameter upon admitting the new service.

The number of HSDPA users in the cell does not exceed the licensed number of users upon admittingthe new service.

The number of HSDPA users in NodeB does not exceed the maximum value specified by theNodeBHsdpaMaxUserNumparameter upon admitting the new service.

Otherwise, the HSDPA service performs Directed Retry Decision (DRD) to access one of the cells thatsupport blind handovers. If none of these cells can be accessed, the HSDPA service is degraded to anR99 service and then attempts to access a cell. For details about DRD, see theDirected Retry DecisionFeature Parameter Description.

6.2 CAC for HSUPA Users

HSUPA admission control is based on the number of HSUPA users.

When a new HSUPA service attempts to access the network, the algorithm admits the service if thefollowing conditions are met:

The number of HSUPA users in the cell does not exceed the maximum value specified by theMaxHsupaUserNum

parameter upon admitting the new service. The number of HSUPA users in the cell does not exceed the licensed number of users upon admitting

the new service.

The number of HSUPA users in NodeB does not exceed the maximum value specified by theNodeBHsupaMaxUserNumparameter upon admitting the new service.

Otherwise, the HSUPA service performs Directed Retry Decision (DRD) to access one of the cells thatsupport blind handovers. If none of these cells can be accessed, the HSUPA service is degraded to anR99 service and then attempts to access a cell.

Call Admission Control 7 CAC Based on Power Resources

7 CAC Based on Power Resources

7.1 Overview

The power-based admission algorithm is optional for admission control. The power-based admissionalgorithm is enabled or disabled by theNBMUlCacAlgoSelSwitch/NBMDlCacAlgoSelSwitchparameter.

To enable power-based admission control for HSDPA or HSUPA services, select HSDPA_UU_ADCTRLorHSUPA_UU_ADCTRLunder theNBMCacAlgoSwitch parameter. This switch does not work when the uplink is overHSUPA channels and the downlink is over HSDPA channels.

CAC based on power resources is performed by using one of the following four algorithms:

Algorithm 1 (ALGORITHM_FIRST): admission control based on the cell power load and the expectedload increase caused by a new service

Depending on the current cell power load, the RNC determines whether the cell load will exceed thethreshold upon admitting the new service. If the cell load exceeds the threshold, the RNC rejects theaccess request. Otherwise, the RNC admits the service.

Algorithm 2 (ALGORITHM_SECOND): admission control based on the equivalent number of users(ENU)

Depending on the current ENU load and the access request, the RNC determines whether the ENUwill exceed the threshold upon admitting the new service. If the ENU exceeds the threshold, the RNCrejects the access request. Otherwise, the RNC admits the service.

Algorithm 3 (ALGORITHM_THIRD): admission control without considering load increase caused by anew service

This algorithm assumes that the load increase caused by the new service is 0. Based on the current

cell power load, the RNC determines whether the cell load will exceed the threshold. If the cell loadexceeds the threshold, the RNC rejects the access request. Otherwise, the RNC admits the service.

Algorithm 4 (ALGORITHM_FOURTH): admission control based on the uplink actual power load andthe expected load increase caused by a new service.

Depending on the current uplink actual power load, the RNC determines whether the cell load willexceed the threshold after admitting the new service. If the cell load exceeds the threshold, the RNCrejects the access request. Otherwise, the RNC accepts the service.

Algorithm 1, 2, and 3 apply to admission control in the uplink and downlink. Algorithm 4 applies only toadmission control in the uplink.

Figure 7-1 shows the basic procedure for a power-based admission decision.

Figure 7-1 Basic procedure for a power-based admission decision

The basic principles for a power-based admission decision are as follows:

For an intra-frequency handover request, only a downlink admission decision is required.

For a non-intra-frequency handover request, both uplink and downlink decisions are required.

If there is a rate downsizing request, the RNC accepts it directly. For a rate upsizing request, bothuplink and downlink admission control are required.

7.2 Power-based Admission Control on RRC Connection SetupRequests

The RNC performs loose or strict admission control on RRC connection setup requests. TheRRCCacChoiceparameter specifies whether to use loose or strict admission control.

Admission control is performed on RRC connection setup requests the same way as it is performed onRAB setup requests, except that the admission thresholds are different. This section only describes theadmission thresholds for RRC connection setup requests in loose and strict admission control. Fordetails about admission control for RAB setup, see section7.3 "Power-based Admission Algorithm 1 forRAB Setup."

If load increase is considered when the RNC performs admission control on an RRC connection setup request, the RNCcalculates the load increase based on the signaling radio bearer (SRB) rate of the RRC connection setup request. TheSRB rate of an RRC connection setup request is set by running the SET URRCESTCAUSEcommand.

Loose Admission Control

If an RRC connection setup request comes from emergency calls, detachments, or registrations, theRRC connection is set up directly.

If an RRC connection setup request comes from other services, admission control is performed asfollows:

When UL_UU_OLCor DL_UU_OLCunder theNBMLdcAlgoSwi tchparameter is set to 1,

If the cell is overloaded, the RRC connection setup request is rejected.

If the cell is not overloaded, the uplink or downlink OLC triggering threshold (UlOlcTrigThdorDlOlcTrigThd)is used for admission control.

When UL_UU_OLCor DL_UU_OLCis set to 0, the uplink or downlink OLC triggering threshold(UlOlcTrigThdorDlOlcTrigThd)is used for admission control.

For details about the state of an overloaded cell and overload control (OLC), see theLoad ControlFeature Parameter Description.

Strict Admission Control

If an RRC connection setup request comes from emergency calls or detachments, the RRC connectionis set up directly.

If an RRC connection setup request comes from other services, the RNC determines the admissionthreshold based on one of the following request causes:

RRC connection setup requests of real-time services

RRC connection setup requests of non-real-time services

RRC connection setup requests of other services (excluding real-time services, non-real-time services,emergency calls, and detachments)

The RNC determines the admission threshold using the following formulas:

Admission threshold for RRC of real-time services = Admission threshold offset for RRC of real-timeservices (RTRRCCacThdOffset)+UlNonCtr lThdForAMR(for the uplink) orDlConvAMRThd(forthe downlink)

Admission threshold for RRC of non-real-time services = Admission threshold offset for RRC ofnon-real-time services (NRTRRCCacThdOffset)+UlNonCtr lThdForOther(for the uplink) orDlOtherThd(for the downlink)

Admission threshold for RRC of other services = Admission threshold offset for RRC of other services(OtherRRCCacThdOffset)+UlOlcTrigThd(for the uplink) orDlOlcTrigThd(for the downlink)

7.3 Power-based Admission Algorithm 1 for RAB SetupThere are two types of power-based admission decisions based on algorithm 1: uplink and downlink.

The RNC performs admission control on services based on cell load. The measurement quantitiesrelevant to cell load are processed and reported by the load measurement module of the RNC. Fordetails about how measurement quantities relevant to cell load are measured and reported, see thesection of load measurements in theLoad Control Feature Parameter Description.

Uplink Power-based Admission Decisions for R99 Cells Based on Algorithm 1

In an R99 cell, uplink power-based admission decisions are made according to the RTWP-based total

uplink load. The RTWP-based total uplink load is calculated in real time by the load measurement

module of the RNC. It is represented by UL,R99-Totaland calculated using the following formula:

Where

PNis the received uplink background noise. It is set by theBackgroundNoiseparameter. If the

auto-adaptive background noise update algorithm is enabled, PNis updated in real time. For detailsabout the auto-adaptive background noise update algorithm, see theLoad Control Feature Parameter

Description.

RTWP is the received total wideband power in the uplink. It is measured by the NodeB and reported to

the RNC periodically.

UL,CCHis the reserved load on the uplink common channels. It is set by theUlCCHLoadFactor

parameter.

Upon receiving a service access request, the RNC makes the uplink power-based admission decision

for an R99 service. The procedure is as follows:

1. The RNC calculates the uplink load increase (UL) based on the initial admission rate of the service.

For details about the initial admission rate, see theLoad Control Feature Parameter Description.

2. If the sum of the RTWP-based total uplink load (UL,R99-Total) and the load increase caused by the new

service (UL) is lower than or equal to the corresponding admission threshold

(UlNonCtr lThdForAMR,UlNonCtr lThdForNonAMR,UlNonCtr lThdForOther,or

UlNonCtr lThdForHo), the RNC admits the service. Otherwise, the RNC performs the next step.

If theCSRABCacOptSwitchparameter is set to ON, the RNC uses the following admission threshold for AMR servicesetup, reconfiguration, or handover requests to increase the access success rate of AMR services:

When the OLC algorithm switch (UL_UU_OLCunder theNBMLdcAlgoSwi tchparameter) is turned on, the uplink OLC

triggering threshold (UlOlcTrigThd)is used as the admission threshold.

When the OLC algorithm switch (UL_UU_OLC under theNBMLdcAlgoSwi tchparameter) is turned off, the admissionthreshold is 100%.

3. The RNC checks whether the control RTWP anti-interference function switch(RTWP_RESIST_DISTURB under theNBMCacAlgoSwitchparameter) is turned on. If it is turnedon, the RNC checks whether the total uplink load of ENU on the cell is lower thanCellUlEquNumCapacity.If it is lower thanCellUlEquNumCapacity,the RNC admits the service.Otherwise, the RNC rejects the access request. For details about the total uplink load of ENU on thecell, see section7.4 "Power-based Admission Algorithm 2 for RAB Setup."

Uplink Power-based Admission Decisions for HSPA Cells Based on Algorithm1

In an HSPA cell, uplink power-based admission decisions are made based on the following load

measurements:

The RTWP-based total uplink load, which is calculated in real time by the load measurement module

of the RNC. It is represented by UL,HSUPA-Totaland calculated using the following formula:

UL,HSUPA-Total= 1 - PN/RTWP + UL,CCH+ HS-DPCCH

Where HS-DPCCHis the reserved load for the uplink HS-DPCCH. It is set by the

UlHsDpcchRsvdFactorparameter. The other variables are defined the same way as for an R99 cell

in "Uplink Power-based Admission Decisions for R99 Cells Based on Algorithm 1."

The uncontrollable uplink load, which is the load factor for the receive power of a cell excluding the

receive power used for scheduling services. It is represented by UL,NonCtrland calculated using the

following formula:

UL,NonCtrl= UL,HSUPA-Total- UL,Ctrl

Where UL,Ctrlis the controllable uplink load and equals the received scheduled E-DCH power share

(RSEPS). RSEPS is the ratio of the receive power of all scheduled users to RTWP in the current cell.

RSEPS is measured by the NodeB and periodically reported to the RNC.

The total uplink load for preferential admission of R99 services, which is represented by UL,R99Prefer-Total.

When the guaranteed bit rate (GBR) for HSUPA services is too high, the RTWP-based total uplink load

may also be too high, and therefore R99 service admission is difficult. In this case, UL,R99Prefer-Total

ensures that R99 services are preferentially admitted. It is calculated using the following formula:

UL,R99Prefer-Total= UL,NonCtrl+ ThdHSUPAMaxGBP+ UL,CCH+ HS-DPCCH

Where ThdHSUPAMaxGBPis the maximum guaranteed load threshold for HSUPA services when the RNC

makes an admission decision on an R99 service. It is set by theHsupaMaxGBPThdparameter.

If the periodic measurement switch of the total receive power used for scheduling services on the E-DCH is turned off

(HSUPA_EDCH_RSEPS_MEASunder theNBMCacAlgoSwitch parameter is set to ), the RNC performs admission

control for the cell based on ENU. For details about ENU-based admission control, see section7.4 "Power-basedAdmission Algorithm 2 for RAB Setup."

Upon receiving a service access request, the RNC performs the uplink power-based admission decision.The procedure is as follows:

1. The RNC calculates the uplink load increase (UL) based on the initial admission rate of the service.

2. The RNC determines whether to admit the service. If service admission succeeds, the RNC admitsthe service. If service admission fails, the RNC performs the next step. Note that the admissioncriteria vary with the bearer type in an HSPA cell, which is described in follow-up sections.

3. The RNC checks whether the control RTWP anti-interference function switch(RTWP_RESIST_DISTURB under theNBMCacAlgoSwitchparameter) is turned on. If it is turnedon, the RNC checks whether the total uplink load of ENU on the cell is lower thanCellUlEquNumCapacity.If it is lower thanCellUlEquNumCapacity,the RNC admits the service.Otherwise, the RNC rejects the access request. For details about the total uplink load of ENU on thecell, see section7.4 "Power-based Admission Algorithm 2 for RAB Setup."

The admission criteria for different bearer types in an HSPA cell are as follows:

For the DCH RAB

If the bearer type is the DCH RAB, a service is admitted only when the following criteria are both met:

The sum of the uncontrollable uplink load (UL,NonCtrl) and the load increase caused by the new service

(UL) is lower than or equal to the corresponding admission threshold (UlNonCtr lThdForAMR,

UlNonCtr lThdForNonAMR,UlNonCtr lThdForOther,orUlNonCtr lThdForHo).

The sum of the RTWP-based total uplink load (UL,HSUPA-Total) and the load increase caused by the new

service (UL), or the sum of the total uplink load for preferential admission of R99 services

(UL,R99Prefer-Total) and the load increase caused by the new service (UL), is lower than or equal to

UlCellTotalThd.

When the OLC algorithm switch (UL_UU_OLCunder theNBMLdcAlgoSwi tchparameter) is turned on, the uplink OLCtriggering threshold (UlOlcTrigThd)is used as the admission threshold.


For the HSUPA RAB

If the bearer type is the HSUPA RAB, the CAC algorithm combines the PBR-based admission decisionwith the load-based admission decision. The RNC admits an HSUPA service if either PBR-basedadmission or load-based admission succeeds.

IMS signaling services carried on HSUPA RABs are admitted directly.

PBR-based admission decisions

The uplink provided bit rate (PBR) is the effective uplink throughput on all UEs corresponding to ascheduling priority indicator (SPI) successfully received by the NodeB. PBR is reported by the NodeBto the RNC periodically.

The RNC performs PBR-based admission control only when the HSUPA PBR measurement switch isturned on (HSUPA_PBR_MEASunder theNBMCacAlgoSwitchparameter is set to 1). If the sum ofPBRs of some UEs is larger than the sum of their GBRs multiplied by a certain factor, the RNCdecides that the QoS requirements of the cell are met. In this case, the RNC can admit new services.PBR-based service admission succeeds if any of the following criteria are met:

Where

ThdLis the PBR threshold (HsupaLowPrior i tyUserPBRThd)for all HSUPA users whosescheduling priorities are lower than the priority of users to be admitted.

ThdEis the PBR threshold (HsupaEqualPrior i tyUserPBRThd)for all HSUPA users whosescheduling priorities are equal to the priority of users to be admitted.

ThdGEis the PBR threshold (HsupaHighPrior i tyUserPBRThd)for all HSUPA users whose

scheduling priorities are higher than the priority of users to be admitted.

Load-based admission decisions

For HSUPA scheduling services, if the sum of the RTWP-based total uplink load (UL,HSUPA-Total) and

the load increase caused by the new service (UL) is lower than or equal toUlCellTotalThd,

load-based service admission succeeds. Otherwise, load-based service admission fails.

For HSUPA non-scheduling services, load-based service admission succeeds only when both of the

following criteria are met:

The sum of the RTWP-based total uplink load (UL,HSUPA-Total) and the load increase caused by the

new service (UL) is lower than or equal toUlCellTotalThd.

The sum of the uncontrollable uplink load (UL,NonCtrl) and the load increase caused by the new

service (UL) is lower than or equal to the corresponding admission threshold

(UlNonCtr lThdForAMR,UlNonCtr lThdForNonAMR,UlNonCtr lThdForOther,or

UlNonCtr lThdForHo).

Otherwise, load-based service admission fails.


When the OLC algorithm switch (UL_UU_OLCunder theNBMLdcAlgoSwi tchparameter) is turned on, the uplink OLCtriggering threshold (UlOlcTrigThd)is used as the admission threshold.


For the DC-HSUPA RAB

Only load-based admission decisions are made for DC-HSUPA RABs.

For DC-HSUPA non-scheduling services, load-based admission decisions are made only on theprimary carrier. The admission method is the same as that for common HSUPA non-schedulingservices.

A DC-HSUPA scheduling service is admitted if the load-based admission decision is successful on theprimary or secondary carrier. The admission decision method is the same as that for a commonHSUPA scheduling service. That is, the sum of the RTWP-based total uplink load (UL,HSUPA-Total) andthe load increase after admitting the DC-HSUPA scheduling service (UL) is lower than or equal toUlCellTotalThdon the primary or secondary carrier.

Downlink Power-based Admission Decisions for R99 Cells Based onAlgorithm 1

In an R99 cell, downlink power-based admission decisions are made according to the TCP-based total

downlink load, which is calculated in real time by the load measurement module of the RNC. It is

represented by DL,R99-Totaland calculated using the following formula:

DL,R99-Total = TCP+ DL,CCH

Where

TCPis equal to the transmitted carrier power (TCP), which is the ratio of the total transmitted power on

one downlink carrier to the maximum transmission power (set by theMaxTxPowerparameter).

DL,CCHis the reserved load on the downlink common channels. It is set by theDlCCHLoadRsrvCoeff

parameter.

Upon receiving a service access request, the RNC makes the downlink power-based admission decision

for an R99 service. The procedure is as follows:

1. The RNC calculates the downlink load increase (DL) based on the initial admission rate of the

service and the pilot signal quality the user receives.

2. If the TCP-based total downlink load (DL,R99-Total) is lower than or equal to the corresponding
