Abstract
A method and an apparatus for operating a timer in an integrated circuit (IC) are disclosed herein. The IC includes a timer a receiver configured to receive a circuit switched (CS) service notification a transmitter configured to transmit an evolved packet system mobility management extended service request (ESR) message and a processor configured to start the timer in response to transmitting the ESR and stop the timer in response to reception of a handover command and completion of a CS fallback procedure by the receiver wherein the handover command directs the IC to handover to another radio access technology (RAT) so that a CS call may be established. The processor may be configured to stop the timer in response to reception of a cell change command and completion of a CS fallback procedure by the receiver wherein the cell change command directs the IC to perform a cell change procedure.

Claim
1. A Wireless Transmit/Receive Unit (WTRU), comprising:
a timer;
a receiver configured to receive a circuit switched (CS) service notification for a CS call;
a processor configured to determine that a CS fallback procedure associated with the CS call is accepted, and generate an evolved packet system mobility management extended service request (ESR) message including information indicating the determined acceptance; and
a transmitter configured to transmit the generated evolved packet system mobility management ESR message,
wherein:
the WTRU is in a connected mode,
the processor is configured to start the timer in response to transmitting the generated ESR, and stop the timer in response to reception by the receiver of a handover command and completion of the CS fallback procedure, and
the handover command directs the WTRU to handover to another radio access technology (RAT) so that the CS call may be established.
2. A Wireless Transmit/Receive Unit (WTRU) comprising:
a timer;
a receiver configured to receive a circuit switched (CS) service notification for a CS call;
a processor configured to determine that a CS fallback procedure associated with the CS call is accepted, and generate an evolved packet system mobility management extended service request (ESR) message including information indicating the determined acceptance; and
a transmitter configured to transmit the generated evolved packet system mobility management ESR message,
wherein:
the WTRU is in a connected mode,
the processor is configured to start the timer in response to transmitting the generated ESR, and stop the timer in response to reception by the receiver of a cell change command and completion of the CS fallback procedure, and
the cell change command directs the WTRU to perform a cell change procedure.
