Enhanced Fast Dormancy 2 Overview

2 Overview

Some intelligent UEs on a live network send a Signaling Connection Release Indication (SCRI) messageto the RNC after PS data transmission is complete. By sending the SCRI message, intelligent UEs

request for a transition to idle mode or the CELL_PCH or URA_PCH state to reduce batteryconsumption. Upon receiving the SCRI, the RNC can release the signaling connection and put the UEinto idle mode, or the RNC can maintain the signaling connection and put the UE to CELL_FACH orCELL_PCH/URA_PCH state. RNC_EFD_D2F_SWITCH of the Optimizat ionSwitch parameter in theSET URRCTRLSWITCH command controls the UE through CELL_FACH to CELL_PCH/URA_PCH ordirectly to CELL_PCH/URA_PCH. These procedures can reduce battery consumption, depending on theUE capability and feature activation on the RNC. By default, the RNC puts the UE into idle mode. A UEsetting up PS services in idle mode consumes more signaling resources than that in the CELL_PCH orURA_PCH state. If there are a large number of UEs transited between idle mode and CELL_DCH state,signaling storms may occur. The EFD feature puts UEs into the CELL_FACH or CELL_PCH state toreduce signaling resource consumption and eliminate signaling storms.

Huawei provides a comprehensive end-to-end solution based on network characteristics to respond to

network challenges. EFD is one component of the solution. This feature alone is not enough to eliminatesignaling storms caused by intelligent UEs. However, when applied with professional services, EFD canbe used to optimize the quality of service (QoS) for the entire network.

Consult Huawei engineers to receive the appropriate parameter settings for this feature along with other comprehensiveprofessional support. Do not configure the EFD parameters without Huawei professional technical support. Inappropriateparameter settings may lead to network failures.

The UEs on a live network can be divided into three types:

UEs that do not send SCRI messages because there is no PS data to be transmitted.

Pre fast dormancy UEs. This type of UE does not read the T323 information element (IE) carried in the

system information block type 1 (SIB1) message. After PS data transmission is complete, this type ofUE sends an SCRI message to the RNC, but the SCRI message does not carry the IE SignalingConnection Release Indication Cause. Both T323 and Signaling Connection Release Indication Causeare introduced in 3GPP Release 8.

R8 fast dormancy UEs. This type of UE reads the T323 IE carried in the SIB1 message and sends anSCRI message to the RNC after PS data transmission is complete. The SCRI message carries the IESignaling Connection Release Indication Cause that is set to "UE Requested PS Data session end."

The T323 IE carried in the SIB1 message controls the frequency at which the R8 fast dormancy UEssend SCRI messages with the IE Signaling Connection Release Indication Cause set to "UE RequestedPS Data session end". The T323 timer starts after an SCRI message is sent by the R8 fast dormancyUEs, and the second SCRI message with the IE Signaling Connection Release Indication Cause set to

"UE Requested PS Data session end" can be sent only after the T323 timer expires.

The EFD feature applies only to the pre fast dormancy UEs and R8 fast dormancy UEs. Users canconfigure EFD to be enabled for only the pre fast dormancy UEs or R8 fast dormancy UEs.

When this feature is disabled, the RNC releases the signaling connection and puts the UE into idle modeafter receiving the SCRI message regardless the UE types.

When this feature is enabled, the RNC performs different processing based on the UE type:

For the pre fast dormancy UEs, the RNC checks for compatibility issues after receiving an SCRImessage. If there are no compatibility issues, the RNC puts the UE into the CELL_FACH or PCH state.If there is a compatibility issue, the RNC puts the UE into idle mode.

For the R8 fast dormancy UEs, the RNC puts the UE into the CELL_FACH or PCH state after receivingan SCRI message.

Some pre fast dormancy UEs may have compatibility issues after moving to the CELL_FACH, CELL_PCH, or URA_PCHstate. As a result, new services cannot be initiated. This feature has been tested by using iPhones and no compatibilityissue occurred.

Enhanced Fast Dormancy 4 Identifying Fast Dormancy UEs



4-1

4 Identifying Fast Dormancy UEs

The RNC identifies the pre fast dormancy UEs and R8 fast dormancy UEs using the followingmechanisms:

R8 fast dormancy: The T323 parameter that can be set in the SET UCONNMODETIMER command issent to the UE by the SIB1 message. The R8 fast dormancy UEs send an SCRI message with the IESignaling Connection Release Indication Cause set to "UE Requested PS Data session end" after PSdata transmission is complete. The RNC identifies the R8 fast dormancy UEs by reading the value ofIE Signaling Connection Release Indication Cause.

This mechanism is standardized by 3GPP Release 8. Some Release 6 and Release 7 smartphones,such as iPhones, have been enabled with the fast dormancy function defined in Release 8.

Pre fast dormancy: The RNC identifies the pre fast dormancy UEs using the Type Allocation Codes(TACs).

This mechanism, which is not standardized, is used for the early proprietary implementations of fastdormancy.

The international mobile equipment identity (IMEI), which consists of 14 decimal digits and one checkdigit, contains TAC and SNR. TAC indicates a particular type of device that has been approved by anational GSM/WCDMA approval body. SNR is the serial number identifying the UE. The structure of theIMEI, which is shown as follows, is specified in 3GPP TS 23.003.

TAC (8bit) SNR (6bit) Spare (1bit)

To identify pre fast dormancy UEs, FD_TAC_MATCH_SWITCH of the PROCESSSWITCH parameter onthe RNC side needs to be turned on. The TAC parameter has been set for the pre fast dormancy UEs bythe ADD UIMEITAC command after FastDormancy is ebabled. The RNC checks the TAC of the IMEI in

the IDENTITY REQUEST message. If the TAC is included in the EFD list, the UE can use EFD.

Enhanced Fast Dormancy 5 State Transitions for Fast Dormancy UEs



5-1

5 State Transitions for Fast Dormancy UEs

When EFD is disabled, upon receiving an SCRI message from a UE, the RNC releases the UE’s RRCconnection. The EFD switches are specified by the RNC-level subparameter

FAST_DORMANCY_SWITCH of the parameter PROCESSSWITCH .

When EFD is enabled, state transition procedures vary according to the UE type as follows:

For R8 fast dormancy UEs and pre fast dormancy UEs in EFD list:

− If the RNC received the SCRI, The RNC transfers the UE to CELL_FACH or CELL_PCH/URA_PCH.The RNC_EFD_D2F_SWITCH of the Optimizat ionSwitch parameter in the SET URRCTRLSWITCHcommand and FD_TAC_FORCE_D2F_SWITCH of the PROCESSSWITCH parameter in the ADDUIMEITAC command controls whether the UE transits to the CELL_FACH or CELL_PCH/URA_PCHstate.

− After PS data transmission is complete, If UE is in CELL_DCH, the PS inactivity timer(PsInactTmrForFstDrmDch ) for EFD in CELL_DCH is started. If the PS inactivity timer for EFD inCELL_DCH expires, the RNC transfers the UE to CELL_FACH or CELL_PCH/URA_PCH.

− After PS data transmission is complete, If UE is in CELL_FACH, the PS inactivity timer(PsInactTmrForFstDrmFach ) for EFD in CELL_FACH is started. If the PS inactivity timer for EFD inCELL_FACH expires, the RNC transfers the UE to CELL_PCH/URA_PCH.

− If UE is transferred to CELL_PCH/URA_PCH, the PS inactivity timer (PsInactTmrForPreFstDrm ) isstarted. If the PS inactivity timer for EFD in CELL_PCH/URA_PCH expires, the RNC transfers the UEto IDLE. The value of this timer should be less than or equal to that of T305 , preventing the UE frombeing always in the CELL_PCH state and unable to enter the idle state.

− If UE is in CELL_PCH/URA_PCH and has something to send and the condition for P2D/U2D is notsatisfied, the RNC instructs the UE to enter the CELL_FACH state.

− TAC-based P2D/U2D transitions. That is, when FD_P2D_SWITCH of PROCESSSWITCH in theADD UIMEITAC command is turned on, a P2D/U2D transition starts if the UE's TAC is identical with theTAC added to the EFD list by running the ADD UIMEITAC command and the UE experiences uplinkdata transmission or has a paging response in the PS domain.

− For details about P2D/U2D transitions related to FACH congestion, see section 4.3 "FACHCongestion Control" in Flow Control Feature Parameter Description.

− If UE is in CELL_FACH and send messages whose traffic volume is higher thanFastDormancyF2DHTvmThd , The RNC will transfer the UE from CELL_FACH to CELL_DCH.

− The main factor for triggering the D2I transitions is FACH congestion. For details about statetransitions due to FACH congestion, see section 4.3 “FACH Congestion Control” in Flow ControlFeature Parameter Description.

− For details about P2U/U2U/D2D/CPC/E-FACH and D2F/F2P based on 4B event state transitions, see

State Transition Feature Parameter Description.

For pre fast dormancy UEs not in EFD list:

− If the RNC received the SCRI, the RNC transfers the UE to IDLE state.

− The state transition for pre fast dormancy UEs not in EFD list is the same to ordinary UEs. For details,see State Transition Feature Parameter Description.

− For details about state transitions due to FACH congestion, see section 4.3 “FACH CongestionControl” in Flow Control Feature Parameter Description.

Figure 5-1 shows the state transitions for R8 fast dormancy UEs and pre fast dormancy UEs in EFD list.

Type Description

D2P

D2UD2F

F2P

F2U

D2P/D2U indicates a transition from CELL_DCH to CELL_PCH/URA_PCH, F2P/F2U from

CELL_FACH to CELL_PCH/URA_PCH, and D2F from CELL_DCH to CELL_FACH.The RNC starts the PS inactivity timer for fast dormancy when inactivity on PS data isdetected.

PsInactTmrForFstDrmDch specifies the PS inactivity timer for CELL_DCH.

PsInactTmrForFstDrmFach specifies the PS inactivity timer for CELL_FACH.

PsInactTmrForPreFstDrm specifies the PS inactivity timer for CELL_PCH/URA_PCH.

If the UE is a fast dormancy UE and is not processing CS services, when the PS inactivitytimer for fast dormancy expires or the RNC receives an SCRI message from the UE, the UEchanges states as follows:

For a UE in the CELL_DCH state:

−

If RNC_EFD_D2F_SWITCH of the Optimizat ionSwitch in the SET URRCTRLSWITCHcommand is turned off or FD_TAC_FORCE_D2F_SWITCH of the PROCESSSWITCH parameter in the ADD UIMEITAC command is turned on, the RNC triggers a D2F transition.

− If RNC_EFD_D2F_SWITCH of the Optimizat ionSwitch in the SET URRCTRLSWITCHcommand is turned on and FD_TAC_FORCE_D2F_SWITCH of PROCESSSWITCH in theADD UIMEITAC command is turned off, the RNC triggers a D2P/D2U transition.

The D2F and F2P/F2U state transitions are recommended for the following reasons:

During an IOT test, some terminal issues occur. Occasionally, terminals fail to establish services after atransition from CELL_DCH to CELL_PCH/URA_PCH. This failure has a bad impact on user experience.

Compare with a state transition from CELL_DCH to CELL_FACH and then to CELL_PCH/URA_PCH,the state transition from CELL_DCH to CELL_PCH/URA_PCH does not improve the network

performance or user experience.

Some terminals send CELL UPDATE message to transfer data immediately after a state transition fromCELL_DCH to CELL_PCH/URA_PCH, which increases the signaling messages and leads to a heavyload on the Uu interface.

For a UE in the CELL_FACH state, the RNC trigger an F2P/F2U state transition.

D2I D2I indicates a transition from CELL_DCH to idle.

D2I is mainly used for FACH congestion. For details about state transitions due to FACHcongestion, see section 4.3 “FACH Congestion Control” in Flow Control Feature ParameterDescription.

P2I/U2I P2I/U2I indicates a transition from CELL_PCH/URA_PCH to idle.

If the UE is in the CELL_PCH/URA_PCH state, when the PS inactivity timer for fast dormancy(specified by PsInactTmrForPreFstDrm ) expires, the RNC releases the UE's RRCconnection and then the UE enters idle mode.

P2D

U2D

P2D/U2D indicates a transition from CELL_PCH/URA_PCH to CELL_DCH.

− TAC-based P2D/U2D transitions. That is, when FD_P2D_SWITCH ofPROCESSSWITCH in the ADD UIMEITAC command is turned on, a P2D/U2D transitionstarts if the UE's TAC is identical with the TAC added to the EFD list by running the ADDUIMEITAC command and the UE experiences uplink data transmission or has a pagingresponse in the PS domain.

− For details about P2D/U2D transitions related to FACH congestion, see section 4.3"FACH Congestion Control" in Flow Control Feature Parameter Description.

Type Description

P2F

U2F

P2F/U2F indicates a transition from CELL_PCH/URA_PCH to CELL_FACH.

When the UE has something to send and the condition for P2D/U2D is not satisfied, the RNC

instructs the UE to enter the CELL_FACH state.

F2D F2D indicates a transition from CELL_FACH to CELL_DCH.

When a fast dormancy UE is in the CELL_FACH state, When the fast dormancy UE sendmessages whose traffic volume is higher than FastDormancyF2DHTvmThd , The RNC willtransfer the UE from CELL_FACH to CELL_DCH. The FastDormancyF2DHTvmThd is anew threshold of event 4a for fast dormancy UE, This threshold is set to bigger than trafficvolume of most heartbeat messages to prevent state transitions from being triggered by asmall-sized heartbeat messages.

Enhanced Fast Dormancy 6 Engineering Guidelines



6-1

6 Engineering Guidelines

6.1 When to Use Enhanced Fast Dormancy

The EFD feature is recommended for scenarios where the proportion of intelligent UEs is high, leadingto a high CPU load on control-plane board in the RNC and on baseband processing boards in the NodeB.This feature reduces the Uu, Iu, and Iub signaling, uplink and downlink channel element (CE)consumption, and CPU load.

For the BSC6900, a signaling processing unit is the SPUa or SPUb board.

For the BSC6910, a signaling processing unit is the EGPUa board.

6.2 Deploying Enhanced Fast Dormancy

This feature cannot be configured using the CME.

6.2.1 Requirements

Dependencies on Hardware

This feature does not have any special requirements for hardware.

Dependencies on Other Features

This feature does not depend on other features.

License

The licenses "Fast Dormancy Enhancement(per PS Active User)" on the RNC side have beenactivated. For details about the license items and how to activate the license, see LicenseManagement Feature Parameter Description.

The license must be activated by performing the following operation first:

Run the RNC MML command SET LICENSE to set Fast Dormancy Enhancement-per PS Active User to anappropriate value.

Other Prerequisites

It is good practice to maintain load balancing among all frequencies in the network when using thisfeature, if the network is a service-layered network as follows andRNC_EFD_D2F_SWITCH(RNC_EFD_D2F_SWITCH) of the Optimization Switch in the SETURRCTRLSWITCH command is set to 0, in order to reduce the call drops for UEs in the CELL_FACHstate that support fast dormancy, Wait RB reconfiguration response timer and RL restorationtimer in the SET USTATETIMER command need to be set to 11000 and 15000 respectively.

− Frequency F1 carries R99 services.

− Frequency F2 carries HSPA services.

− F2 does not allow UEs in the idle, CELL_FACH, or CELL_PCH state to camp on.

6.2.2 Data Preparation

Before deploying the feature, consult Huawei engineers to obtain professional technical support.



WCDMA RAN




6-2

6.2.3 Feature Activation (The UE supporting fast dormancy is aPre-Release 8 UE)

1. Run the RNC MML command SET URRCTRLSWITCH to enable the feature Enhanced Fast

Dormancy at the RNC-level. In this step, select the FAST_DORMANCY_SWITCH under thePROCESSSWITCH.

2. Run the RNC MML command SET URRCTRLSWITCH to select theRNC_PS_QUERY_UE_IMEI_SWITCH under the PROCESSSWITCH2.

3. Run the RNC MML command SET URRCTRLSWITCH to enable cell update during CS service setup.In this step, select theAMR_F2D_OVERLAP_CELLUPT_SWITCH(AMR_F2D_OVERLAP_CELLUPT_SWITCH) checkbox under the parameter Optimization Switch.

After this feature is enabled, the number of CELL_DCH-to-CELL_FACH (D2F) procedures performed increases. If a CSservice is initiated after the UE performs a D2F procedure, a cell update procedure may be initiated during the CS servicesetup. The switch AMR_F2D_OVERLAP_CELLUPT_SWITCH(AMR_F2D_OVERLAP_CELLUPT_SWITCH) specifies

whether to allow cell update during CS service setup. When the switch is turned on, for UEs that are establishing AMRservices and shifting from the CELL_FACH state to the CELL_DCH state, the RNC stops establishing AMR services tohandle cell update if the RNC receives from the UEs a cell update message containing the cause value "cell reselection."

4. Run the RNC MML command SET URRCTRLSWITCH to enable the state transition fromCELL_PCH or URA_PCH to CELL_DCH triggered by FACH congestion. In this step, select theP2D_SWITCH(P2D_SWITCH) check box under the parameter Optimization Switch.

5. Run the RNC MML command SET URRCTRLSWITCH to enable the state transition fromCELL_DCH to CELL_FACH. In this step, select theRNC_EFD_D2F_SWITCH(RNC_EFD_D2F_SWITCH) check box under the parameter OptimizationSwitch.

The switch RNC_EFD_D2F_SWITCH(RNC_EFD_D2F_SWITCH) specifies whether to allow the state transition fromCELL_DCH to CELL_FACH. When this switch is turned on, the state transition from CELL_DCH to CELL_FACH isallowed. When this switch is turned off, the state transition from CELL_DCH to CELL_PCH is allowed.

After this feature is enabled, the FACH will carry a large amount of data, which may lead to FACH congestion. Therefore, itis recommended that a new SCCPCH be added.

For details about how to handle FACH congestion in other methods, see section "FACH Congestion Control" in the FlowControl Feature Parameter Description.

6. Run the RNC MML command SET UPSINACTTIMER to set the value of the CELL_DCH,CELL_FACH, and CELL_PCH inactivity timer respectively.

− The recommended value of the FAST DORMANCY USER T1 in CELL_DCH is 5 seconds.

− The recommended value of the FAST DORMANCY USER T1 in CELL_FACH is 5 seconds.

−

The recommended value of the FAST DORMANCY USER T1 in CELL_PCH is 1800 seconds.

This document provide the recommended value of the FAST DORMANCY USER T1 in CELL_DCH, the FASTDORMANCY USER T1 in CELL_FACH, and the FAST DORMANCY USER T1 in CELL_PCH.

7. Run the RNC MML command SET UUESTATETRANS. In this step, set Fast Dormancy UserFACH/E_FACH2DCH/HSPA 4A Threshold to D1024.

8. Run the RNC MML command SET URRCTRLSWITCH to enable the Type Allocation Code (TAC)match function. In this step, select the FD_TAC_MATCH_SWITCH under the PROCESSSWITCH.

Run the RNC MML commandADD UIMEITAC to set the value of the TAC to add the IMEI TACs ofsmart UEs to the whitelist, and set the Fast Dormancy Switch to ON.



WCDMA RAN




6-3

9. Run the RNC MML command ADD TRMFACTOR and MOD ADJMAP to change the Iu-PS activityfactor. The recommended value of the Iu-PS activity factor is 10%. If the configured Iu-PS activityfactor is smaller than 10%, retain the configured value.

After this feature is enabled, the number of UEs in the CELL_PCH or URA_PCH state increases sharply. UEs in theCELL_PCH or URA_PCH state consume a large number of Iu-PS bandwidth resources although they do not transmit anydata.

Adjusting the Iu-PS activity factor can prevent PS service admission failures due to the increase in the number of UEs inthe CELL_PCH or URA_PCH state.

The Iu-PS activity factor of all services must be set to an appropriate value. Otherwise, a large number ofPS service setups fail, and the CPU usage of the SPU boards increases sharply.

6.2.4 Feature Activation (The UE supporting fast dormancy is aRelease 8 or later Release UE)

1. Run the RNC MML command SET URRCTRLSWITCH to enable the feature Enhanced FastDormancy at the RNC-level. In this step, select the FAST_DORMANCY_SWITCH under thePROCESSSWITCH.

2. Run the RNC MML command SET UCONNMODETIMER to set the value of the Timer 323.

If the UE supporting fast dormancy is a Release 8 or later Release UE, you need to set timer 323 after enabling fastdormancy. When the network supports the CELL_PCH or URA_PCH, it is good practice to set timer 323 to 120s. Whenthe network does not support CELL_PCH or URA_PCH, it is good practice to set timer 323 to 10s.

3. Run the RNC MML command SET URRCTRLSWITCH to enable cell update during CS service setup.In this step, select theAMR_F2D_OVERLAP_CELLUPT_SWITCH(AMR_F2D_OVERLAP_CELLUPT_SWITCH) checkbox under the parameter Optimization Switch.

After this feature is enabled, the number of CELL_DCH-to-CELL_FACH (D2F) procedures performed increases. If a CSservice is initiated after the UE performs a D2F procedure, a cell update procedure may be initiated during the CS servicesetup. The switch AMR_F2D_OVERLAP_CELLUPT_SWITCH(AMR_F2D_OVERLAP_CELLUPT_SWITCH) specifieswhether to allow cell update during CS service setup. When the switch is turned on, for UEs that are establishing AMR

services and shifting from the CELL_FACH state to the CELL_DCH state, the RNC stops establishing AMR services tohandle cell update if the RNC receives from the UEs a cell update message containing the cause value "cell reselection."

4. Run the RNC MML command SET URRCTRLSWITCH to enable the state transition fromCELL_PCH or URA_PCH to CELL_DCH triggered by FACH congestion. In this step, select theP2D_SWITCH(P2D_SWITCH) check box under the parameter Optimization Switch.

5. Run the RNC MML command SET URRCTRLSWITCH to disable the state transition fromCELL_DCH to CELL_PCH. In this step, select theRNC_EFD_D2F_SWITCH(RNC_EFD_D2F_SWITCH) check box under the parameter OptimizationSwitch.

The switch RNC_EFD_D2F_SWITCH(RNC_EFD_D2F_SWITCH) specifies whether to allow the state transition fromCELL_DCH to CELL_FACH. When this switch is turned on, the state transition from CELL_DCH to CELL_FACH is

allowed. When this switch is turned off, the state transition from CELL_DCH to CELL_PCH is allowed.

After this feature is enabled, the FACH will carry a large amount of data, which may lead to FACH congestion. Therefore, itis recommended that a new SCCPCH be added.

For details about how to handle FACH congestion in other methods, see section "FACH Congestion Control" in the FlowControl Feature Parameter Description.

6. Run the RNC MML command SET UPSINACTTIMER to set the value of the CELL_DCH,CELL_FACH, and CELL_PCH inactivity timer respectively.

− The recommended value of the FAST DORMANCY USER T1 in CELL_DCH is 5 seconds.

− The recommended value of the FAST DORMANCY USER T1 in CELL_FACH is 5 seconds.

− The recommended value of the FAST DORMANCY USER T1 in CELL_PCH is 1800 seconds.

This document provide the recommended value of the FAST DORMANCY USER T1 in CELL_DCH, the FASTDORMANCY USER T1 in CELL_FACH, and the FAST DORMANCY USER T1 in CELL_PCH.

7. Run the RNC MML command SET UUESTATETRANS. In this step, set Fast Dormancy UserFACH/E_FACH2DCH/HSPA 4A Threshold to D1024.

8. Run the RNC MML command SET URRCTRLSWITCH to enable the Type Allocation Code (TAC)

match function. In this step, select the FD_TAC_MATCH_SWITCH under the PROCESSSWITCH.9. Run the RNC MML command ADD TRMFACTOR and MOD ADJMAP to change the Iu-PS activity

factor. The recommended value of the Iu-PS activity factor is 10%. If the configured Iu-PS activityfactor is smaller than 10%, retain the configured value.

After this feature is enabled, the number of UEs in the CELL_PCH or URA_PCH state increases sharply. UEs in theCELL_PCH or URA_PCH state consume a large number of Iu-PS bandwidth resources although they do not transmit anydata.

Adjusting the Iu-PS activity factor can prevent PS service admission failures due to the increase in the number of UEs inthe CELL_PCH or URA_PCH state.

The Iu-PS activity factor of all services must be set to an appropriate value. Otherwise, a large number ofPS service setups fail, and the CPU usage of the SPU boards increases sharply.

6.2.5 Activation Check

1. Run the RNC MML command DSP LICUSAGE to query the state of the license for this feature. If theresult shown in Figure 6-1 is returned, the license for this feature has been configured.

Figure 6-1 Status of the Enhanced Fast Dormancy license

2. Initiate Uu interface message tracing on the RNC LMT.

3. Use a smart UE that its IMEI TAC has been added into whitelist to set up a PS service in theCELL_DCH state. For example, use the UE to browse a Web page.

If the RRC_RB_SETUP message shown in Figure 6-2 is traced, the UE is in the CELL_DCH state.

Meaning:1) FD_P2D_SWITCH (TAC-LevelP2D Control Switch)

When the switch is turned on, state transitionfrom CELL_PCH/URA_PCH to CELL_DCH of aUE is triggered if the following conditions aremet:

1. The TAC of the UE is the same as thatconfigured on the RNC.

2. The UE is in the CELL_PCH or URA_PCH

state, and the RNC receives a CELL UPDATEmessage containing a cause value of "uplinkdata transmission" or "PS paging response."

When the switch is turned off, state transitionfrom CELL_PCH/URA_PCH to CELL_DCH isnot triggered by the CELL UPDATE messagecontaining "uplink data transmission" or "PSpaging response."

In this case, however, the state transition canbe triggered by other factors in the system. Forexample, if the UE is in the CELL_PCH or

URA_PCH state, the state transition toCELL_DCH can be triggered by a CSterminated call.

2) FD_TAC_FORCE_D2F_SWITCH(TAC-based D2F Switch for UEs SupportingFast Dormancy)

When the switch is turned on, state transitionfrom CELL_DCH to CELL_FACH is forciblyperformed on the UE with the correspondingTAC and supporting fast dormancy.

When both this switch and the RNC-levelCELL_DCH-to-CELL_FACH (D2F for short)switch are turned off, CELL_DCH toCELL_PCH/URA_PCH state transition isforcibly performed on the UE with thecorresponding TAC and supporting fastdormancy.

10)CR2284R1_SWITCH.

In section 8.6.6.28 of TS25.331 of R5Before2006, it describes that the HFN shouldadd one when UE is ciphering in the situation ofTiming re-initialized hard handover, while notspecified in RB SETUP process in the sectionof 8.6.4.3. so it is not clear whether to add ornot in RB SETUP in DRD scenarios.CR2284R1 clarify that HFN should add one inRB SETUP process with Timing re-initialized

hard handover. when it is checked ,RNCaccepts this CR2284R1; when it is notchecked ,RNC does not accept this CR2284R1.

11)CDT_MSG_FULL_TRACE.

When it is checked, CDT trace function whichstarts tracing from message RRC CONNECTREQUEST.

12)CR2284R1_COMPATIBLE_SWITCH.

CR2284R1 causes the compatible problem. ifUE is not consistent with RNC regardingwhether accept the CR2284R1 or not, it willcause the problem of streaming when UEs arecommunicating with each other. So RNCcreates this switch. when it is checked, RNC isauto-adaptive to accept the CR2284R1according to UE version information. Theprinciples that RNC judges UE whether toaccept the CR2284R1 are as follows: R5 andabove UE accepts the CR; R99/R4 UE, if itreceives the START LIST value from RBSETUP COMPLETE,RNC figures that UEaccepts the CR; R99/R4 UE, if it only receives

the START value from RB SETUPCOMPLETE,RNC figures that UE does notaccept the CR; when it is not checked, whetherRNC accept the CR or not is according toCR2284R1_SWITCH. The relations betweenthese two switches CR2284R1_SWITCH andCR2284R1_COMPATIBLE_SWITCH are asfollows:

(1)CR2284R1_COMPATIBLE_SWITCH ischecked, RNC is self-compatible, so theCR2284R1_SWITCH is invalid;

When this switch is turned on, if a UE sets up anon-PTT service on the DCH, the RNC includesthe Post-verification period information element(IE) in a Uu message to instruct the UE toperform concurrent uplink and downlinksynchronization.

When this switch is turned off, if a UE sets up anon-PTT service on the DCH, the RNC doesnot include the Post-verification period IE in aUu message. The UE first performs downlinksynchronization and then uplinksynchronization.

24)URAPCH_LAYERED_PAGING_RT_SWITCH.

Whether the RNC allows Layered Paging inURA_PCH for a UE processing real-timeservices.

When this switch is turned on, the RNC sendspaging messages to the cell on which a UEprocessing real-time services camped recentlyand to the neighboring cells of this cell. TheRNC pages the UE in the entire UTRANregistration area (URA) only when it does notreceive a response from the UE. Thissignificantly reduces the number of pagingmessages on the Uu interface.

When this switch is turned off, the RNC directlypages the UE in the entire URA.
