WCDMA RANFast Dormancy 2 Overview


2-1

2 OverviewWhen fast dormancy or enhanced fast dormancy is applied, the UE can request the RNC to release thePS signaling connection if no more PS data is transmitted. After receiving the request, the RNC can

either release the signaling connection and put the UE into idle mode, or maintain the signalingconnection and put the UE into an efficient battery consumption RRC state such as IDLE, CELL_PCH.



WCDMA RANFast Dormancy 3 Fast Dormancy


3-1

3 Fast DormancyUEs complying with 3GPP Release 8 support the fast dormancy function, as defined in 3GPP TS 25.331CR3483. After a UE processing only PS services finishes the PS data transmission, it sends the RNC a

Signaling Connection Release Indication (SCRI) message, which contains the cause value of "UERequested PS Data session end". Upon receiving the message, the RNC releases the RRC connectionof the UE and enables the UE to quickly enter the power saving mode.

The following figure shows the procedure of fast dormancy.

Figure 3-1 Fast dormancy

The RNC sends timer T323 in SIB1 or UTRAN Mobility Information to the UE to control fast dormancy.

If the value of T323 is INVALID, the timer is not sent to the UE, and accordingly the UE does not sendthe SCRI message containing the information element (IE) "UE Requested PS Data session end".

If the value of T323 is 0, the UE sends the release request only once.

If the value of T323 is a value other than 0, the UE sends the release request and initiates timer T323.The UE sends the release request again after T323 expires.

4 Enhanced Fast Dormancy

4.1 Overview

As the number of intelligent UEs keeps increasing in mobile networks, the networks face signalingstorms produced by these UEs. With many customers all over the world, Huawei has rich experience innetwork optimization. Huawei can provide a comprehensive end-to-end solution to respond to networkchallenges based on network characteristics. This feature is a component of the comprehensive solution.Deploying this feature only cannot solve the signaling storm problem caused by intelligent UEs. It isrecommended that this feature together with professional services be deployed to optimize the quality ofservice of the entire network.

Note:

Consult Huawei engineers about the comprehensive solution to obtain professional technical support. Huawei engineerswill recommend the appropriate parameter settings for this feature based on the network conditions.

Do not configure the parameters related to this feature without Huawei professional technical support. Inappropriateparameter settings may lead to network failures.

Enhanced fast dormancy applies to a network that serves a large number of intelligent UEs supportingfast dormancy. This function can reduce the signaling processing efforts of the RNC and avoid overflowof the signaling processing unit in the RNC that fast dormancy may cause.

To save power, when there is no PS data transmission, an intelligent UE sends the RNC an SCRImessage to request the RRC connection release or to indicate to the UTRAN that one of its signalingconnections has been released. In addition, the UE periodically sends the heartbeat messages (to checknew mails in the mail server for example) to the core network.

If fast dormancy (instead of enhanced fast dormancy) is applied, the RNC releases the RRC connectionas specified by the 3GPP specifications. In such a case, the heartbeat messages will lead to performingthe procedures of RRC connection setup, authentication, encryption, and RAB setup. This greatly

increases the signaling processing efforts of the RNC and may cause overflow of the signalingprocessing unit in the RNC.

Enhanced fast dormancy is introduced to solve the preceding problem. With the application of enhancedfast dormancy, the RNC changes the UE state to CELL_PCH instead of idle mode after receiving theSCRI message from the UE. In such a case, when the UE periodically sends the heartbeat messages,the signaling procedure between the UE and RNC is simplified because the RRC connection ismaintained. As the number of signaling exchange messages decreases, the CPU resources of the RNCcan be saved significantly, and the UE consumes as less battery energy as a UE in idle mode.

The following figure shows the comparison between fast dormancy and enhanced fast dormancy.

Figure 4-1 Comparison between fast dormancy and enhanced fast dormancy

4.2 Identifying Fast Dormancy UEs

Two types of the fast dormancy mechanism are implemented in UEs. These UEs are referred to as fast

dormancy UEs in this document. R8 fast dormancy: This mechanism is standardized by 3GPP Release 8. As specified, the UE sends a

SIGNALLING CONNECTION RELEASE INDICATION (SCRI) message to the network with the IE“Signaling Connection Release Indication Cause” set to "UE Requested PS Data session end."

The RNC can identify this type of UE by the SCRI message with IE "UE Requested PS Data sessionend."

Pre-R8 fast dormancy: This mechanism, which is not standardized, is used for the early proprietaryimplementations of fast dormancy prior to Release 8.

The RNC can identify this type of UE by its IMEI and its release version.

After the RNC receives the Security Mode Command Complete message from the UE, the RNC

identifies fast dormancy UEs as follows: If the FD_TAC_MATCH_SWITCH of the parameter PROCESSSWITCH is turned on, the following

UEs are identified as fast dormancy UE.

− UE (Pre-R8 fast dormancy) that complies with 3GPP Release 5 or later releases and whose IMEIfalls into the white list. The IMEI range for white list is specified by the binary group (TAC ,FastDormancy = ON) in the RNC MML command ADD UIMEITAC. If the FastDormancy switch ison, the RNC considers the UEs specified by the IMEI (TAC ) as capable of enhanced fast dormancy.

− UE (R8 fast dormancy) from which the SCRI message whose cause value is "UE Requested PSData session end." is sent.

If the FD_TAC_MATCH_SWITCH of the parameter PROCESSSWITCH is turned off, the followingUEs are identified as fast dormancy UE.





4-3

− UEs complying with 3GPP Release 5 or later releases are identified as fast dormancy UE excludingthe UEs in the black list..The IMEI range for the black list is specified by the binary group (TAC,FastDormancy = OFF) in the RNC MML command ADD UIMEITAC. If the FastDormancy switch isOFF, the RNC considers the UEs specified by the IMEI (TAC) as incapable of enhanced fastdormancy.

The RNC can obtain the IMEI of the UE from the UE's response to the "IDENTITY REQUEST" message.The range of the IMEI is specified by the parameter TAC in the RNC MML command ADD UIMEITAC.

The IMEI (consisting of 14 decimal digits and one check digit) contains information on the origin, model,and serial number of the UE. The structure of the IMEI is specified in 3GPP TS 23.003.

TAC (8bit) FAC (2bit) SNR (6bit) Spare (1bit)

The Type Allocation Code (TAC) indicates the particular type of device that has been approved by anational GSM/WCDMA approval body. In the 3GPP specifications released later than 2003, the TAClength is changed from 6 bit to 8 bit.

The Final Assembly Code (FAC), which is manufacturer-specific, indicates the location where the UEis manufactured.

SNR is the serial number identifying the UE.

The RNC can determine whether a UE supports fast dormancy according to the information on themanufacturer and model contained in the TAC.

4.3 State Transition of Fast Dormancy UEs

If enhanced fast dormancy is disabled, the RRC connection of the UE is released after the RNC receivedthe SCRI. The switches of enhanced fast dormancy are specified by the RNC level subparameterFAST_DORMANCY_SWITCH of the parameter PROCESSSWITCH and cell level subparameterFAST_DORMANCY_ADCTRL of the parameter NBMCacAlgoSwitch.

If enhanced fast dormancy is enabled, then

If the UE is identified as R8 UE (the UE can report the SCRI with R8 extensional cause of “datasession end”),

− If the RNC received the SCRI with the cause of “data session end”, the RNC transfers the UE toCELL_FACH or CELL_PCH.

If the UE in not R8 UE and the UE is identified as fast dormancy UE,

− If the RNC received the SCRI or if the inactive timer for enhanced fast dormancy times out, the RNCtransfers the UE to CELL_FACH or CELL_PCH.

The following figure shows the detailed state transition of a fast dormancy UE.





4-4

Figure 4-2 State transition of a fast dormancy UE

Table 4-1 State Transition of Fast Dormancy UEs

Type Description

D2PD2F

F2P

D2P is from CELL_DCH to CELL_PCH. F2P is from CELL_FACH to CELL_PCH. D2F is fromCELL_DCH to CELL_FACH.

The RNC starts the PS inactivity timer for fast dormancy after the fast dormancy UE changes the

state. 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

If the UE is a fast dormancy UE and is not processing CS services, when the PS inactivation timerfor fast dormancy expires or the RNC receives the SCRI message or 4B event from the UE, thestate transition of the UE is performed as follows:

If the UE is in the CELL_DCH state,

− If RSVDBIT1_BIT29 in SET URRCTRLSWITCH is set to 0, RNC will trigger the D2F statetransition.

− If RSVDBIT1_BIT29 in SET URRCTRLSWITCH is set to 1, RNC will trigger the D2P statetransition.

If the UE is in the CELL_FACH state,

− The RNC will trigger F2P state transition.

D2I D2I is from CELL_DCH to IDLE.

When the FACH is congested, D2F won’t be triggered for inactive CELL_DCH users. Instead,RNC will trigger D2I to release this UE.

The default D2I function switch is off. You can switch on the function through the followingcommand:

SET UCORRMALGOSWITCH: ReservedSwitch0=RESERVED_SWITCH_0_BIT16-1;





4-5

P2I P2I is from CELL_PCH to IDLE.

If the UE is in the CELL_PCH state, when the PS inactivation timer for fast dormancyPsInactTmrForPreFstDrm expires, the RNC releases the RRC connection and then the UEenters the IDLE state.

P2D P2D is from CELL_PCH to CELL_DCH.

If the switch RsvdPara1 > RSVDBIT1_BIT20 (SET URRCTRLSWITCH) is turned on:

When the UE tries to set up an originated or a terminated CS service and the FACH iscongested, the RNC instructs the UE to perform P2D state transition instead of P2F2D.

SET URRCTRLSWITCH: RsvdPara1=RSVDBIT1_BIT20-0;

Note: for the switch, the value 0 means on and 1 means off.

If the switch PROCESSSWITCH > FD_P2D_SWITCH (ADD UIMEITAC) is turned on:

If the TAC of the UE is the same as that configured on the RNC and if the UE is in theCELL_PCH and the UE is going to transmit uplink data or respond to paging message, the RNCinstructs the UE to perform P2D directly.

P2F P2F is from CELL_PCH to CELL_FACH.

When the UE transmits the heartbeat messages or traffic data, the RNC instructs the UE to enterthe CELL_FACH state.

F2D F2D is From CELL_FACH to CELL_DCH.

When the fast dormancy UE is in the CELL_FACH state, the state transition of the UE isperformed as follows:

If the UE reports event 4A to the RNC, the RNC instructs the UE to enter the CELL_DCH state.

If the UE reports event 4B to the RNC, the RNC instructs the UE to enter the CELL_PCH state.

When the fast dormancy UE periodically sends small heartbeat messages, the normal state

transition mechanism will change the UE status from the CELL_FACH state to CELL_DCH state.To prevent the state transition triggered by small heartbeat messages, a new threshold for Event4A (FastDormancyF2DHTvmThd) is introduced.

To avoid too many UEs remaining in the CELL_FACH state, fast dormancy ensures that the statetransition switch does not affect the 4A and 4B measurement and state transition fromCELL_FACH to other state for fast dormancy UEs in CELL_FACH.
