METHOD AND APPARATUS FOR STATE/MODE TRANSITIONING
A user equipment implements a method of processing indication messages, such as SCRI (signalling connection release indication) messages. The use equipment (UE) maintains a count of how many indication messages with a cause set have been sent by the UE while in at least one radio resource control (RRC) state. The counter is reset responsive to entering idle mode from at least one RRC state.
1 . A method performed by a user equipment (UE), the method comprising:
at the user equipment, maintaining a count of how many indication messages with a cause set have been sent by the UE while in at least one radio resource control (RRC) state;
entering idle mode from the at least one RRC state; and
resetting the count responsive to entering idle mode from the at least one RRC state.
2 . The method of claim 1 , wherein the at least one RRC state comprises a state in RRC Connected mode.
3 . The method of claim 1 , wherein the indication messages comprise signaling connection release indication messages.
4 . The method of claim 1 , wherein the indication messages in the count each have a cause set to UE Requested PS Data session end.
5 . The method of claim 1 , wherein the cause is set to UE Requested PS Data session end.
6 . The method of claim 1 , wherein the at least one RRC state comprises one of a CELL_PCH state or a URA_PCH state.
7 . The method of claim 1 , wherein maintaining a count comprises using a counter.
8 . A user equipment (UE) comprising at least one processor configured to:
maintain a count of how many indication messages with a cause set have been sent by the UE while in at least one radio resource control (RRC) state;
enter idle mode from the at least one RRC state; and
reset the count responsive to entering idle mode from the at least one RRC state.
9 . The user equipment of claim 8 , wherein the at least one RRC state comprises a state in RRC Connected mode.
10 . The user equipment of claim 8 , wherein the indication messages comprise signaling connection release indication messages.
11 . The user equipment of claim 8 , wherein the indication messages in the count each have a cause set to UE Requested PS Data session end.
12 . The user equipment of claim 8 , wherein the cause is set to UE Requested PS Data session end.
13 . The user equipment of claim 8 , wherein the at least one RRC state comprises one of a CELL_PCH state or a URA_PCH state.
14 . The user equipment of claim 8 , further comprising a counter for maintaining the count.
15 . The method of claim 1 , further comprising determining whether a current value of the count is equal to or exceeds a predetermined value.
16 . The method of claim 15 , further comprising, in responsive to the determination, stopping the sending of further indication messages with the cause set.
17 . The user equipment of claim 8 , further configured to determine whether a current value of the count is equal to or exceeds a predetermined value.
18 . The user equipment of claim 17 , further configured to, in responsive to the determination, stop the sending of further indication messages with the cause set.
