1. A method comprising:
- when no more packet switched data is expected at an upper layer of a user equipment (UE) for a prolonged period, and when an inhibit timer is not running, and when the UE is in a CELL_PCH state or a URA_PCH state, and when a count of signaling connection release indication (SCRI) messages sent by the UE is less than a maximum number, the count of SCRI messages associated with at least one of the CELL_PCH state or the URA_PCH state, performing operations of;
incrementing the count of SCRI messages sent by the UE,setting a cause in a SCRI message to UE Requested PS Data session end,sending the SCRI message to a network for a transition of the UE to a battery-efficient radio resource control (RRC) state or to an idle mode, andresetting the count of SCRI messages upon satisfaction of at least one reset condition, the at least one reset condition comprising the UE entering RRC Connected mode.

Abstract
A user equipment implements a method of processing indication messages, such as SCRI (signaling connection release indication) messages. If upper layers indicate that there is no more packet switched data for a prolonged period, then if a count of how many indication messages have been triggered in at least one RRC (radio resource control) state is less than a maximum number, the UE increments the count, and a cause is set in the indication message, and the indication message is sent.

8. A user equipment (UE) comprising at least one memory and a processor, configured to:
when no more packet switched data is expected at an upper layer of a user equipment (UE) for a prolonged period, and when an inhibit timer is not running, and when the UE is in a CELL_PCH state or a URA_PCH state, and when a count of signaling connection release indication (SCRI) messages sent by the UE is less than a maximum number, the count of SCRI messages associated with at least one of the CELL_PCH state or the URA_PCH state, perform operations to; increment the count of SCRI messages sent by the UE, set a cause in a SCRI message to UE Requested PS Data session end, send the SCRI message to a network for a transition of the UE to a battery-efficient radio resource control (RRC) state or to an idle mode, and reset the count of SCRI messages upon satisfaction of at least one reset condition, the at least one reset condition comprising the UE entering RRC Connected mode. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method comprising:
-
determining if, at an upper layer of a user equipment (UE), no more packet switched data is expected for a prolonged period; determining if, at the UE, an inhibit timer is running; determining if the UE is in a CELL_PCH state or a URA_PCH state; determining, at the UE, if a count of signaling connection release indication (SCRI) messages sent by the UE is less than a maximum number, the count of SCRI messages associated with at least one RRC state comprising the CELL_PCH state or the URA_PCH state; and if no more packet switched data is expected for a prolonged period, and if the inhibit timer is not running, and if the UE is in a CELL_PCH state or a URA_PCH state, and if the count of SCRI messages sent by the UE is less than the maximum number, incrementing the count of SCRI messages sent by the UE, setting a cause in a SCRI message to UE Requested PS Data session end, sending the SCRI message to a network for a transition of the UE to a battery-efficient radio resource control (RRC) state or to an idle mode, and resetting the count of SCRI messages upon satisfaction of at least one reset condition, the at least one reset condition comprising the UE entering RRC Connected mode. - View Dependent Claims (16, 17, 18, 19, 20)
