Fast Dormancy 2 Overview



2-1

2 Overview

When fast dormancy, enhanced fast dormancy, or standard fast dormancy is applied, the UE can request the RNC to release the PS signaling connection if no more PS data is being transmitted. Upon receiving such a request, the RNC can either release the signaling connection and put the UE into idle mode, or maintain the signaling connection and put the UE through Cell_FACH to CELL/URA_PCH state to reduce battery consumption.

The descriptions about fast dormancy, enhanced fast dormancy, and standard fast dormancy are as follows:

With fast dormancy, after receiving a Signaling Connection Release Indication (SCRI) message from a UE, the RNC releases the UE RRC connection regardless of whether the message contains the cause value "UE Requested PS Data session end."

With enhanced fast dormancy, UEs send SCRI messages that do not contain the cause value "UE Requested PS Data session end" to the RNC. After receiving such an SCRI message, the RNC moves the UE through Cell_FACH to CELL/URA_PCH state.

Standard fast dormancy is applicable to fast dormancy UEs that comply with 3GPP Release 8 (R8 for short). With standard fast dormancy, UEs send SCRI messages that contain the cause value "UE Requested PS Data session end" to the RNC. After receiving such an SCRI message, the RNC moves the UE through Cell_FACH to CELL/URA_PCH state. Standard fast dormancy is valid only when the RNC has enabled the timer T323 in system information block type 1 (SIB1).
