STATE OR MODE TRANSITION TRIGGERING BASED ON SRI MESSAGE TRANSMISSION

摘要

A user equipment, UE, implements a method of processing (generating) indication messages, such as SCRl (signalling connection release indication) messages (in order to trigger a transition between states like e.g. CeIl-PCH, URA-PCH or Cell-Fach). If upper layers indicate that there is no more packet switched data for a prolonged period (e.g. no data exchange between the UE and the network for a certain period, usually estimated using an *inhibit timer"), then if a count of how many indication messages (i.e. SCRI message) have been triggered (i.e. transmitted) in at least one RRC (radio resource control) state is less than a maximum number, the UE increments the count, a cause is set in the indication message (i.e. "UE Requested PS data session end"), and the indication message (i.e. the SCRI) is sent.
