Abstract

A user equipment implements a method of processing indication messages, such as SCRI (signaling connection release indication) messages. For at least one RRC (radio resource control) state, if the current RRC state of the UE is a result of a previously sent indication, the UE inhibits itself from sending a further indication message.

Claims

1. A method comprising:

maintaining, by a user equipment (UE), a count of signaling connection release indication (SCRI) messages sent by the UE to a network, wherein at least one of the SCRI messages comprises a transition indicator;

entering radio resource control (RRC) Connected mode; and

after entering the RRC Connected mode, resetting the count of SCRI messages.

2. The method of claim 1, wherein the SCRI messages sent by the UE each has a cause set.

3. The method of claim 2, wherein the cause is set to UE Requested PS Data session end.

4. The method of claim 1, wherein the SCRI messages are sent by the UE while in at least one radio resource control (RRC) state.

5. The method of claim 4, wherein the at least one RRC state comprises a CELL_PCH state or a URA_PCH state.

6. The method of claim 1, wherein maintaining a count comprises using a counter.

7. The method of claim 1, wherein said maintaining includes incrementing the count.

8. A user equipment (UE), comprising:

a memory; and

at least one hardware processor communicatively coupled with the memory and configured to;

maintain a count of signaling connection release indication (SCRI) messages sent by the UE to a network, wherein at least one of the SCRI messages comprises a transition indicator;

enter radio resource control (RRC) Connected mode; and

after entering the RRC Connected mode, reset the count of SCRI messages.

9. The UE of claim 8, wherein the SCRI messages sent by the UE each has a cause set.

10. The UE of claim 9, wherein the cause is set to UE Requested PS Data session end.

11. The UE of claim 8, wherein the SCRI messages are sent by the UE while in at least one radio resource control (RRC) state.

12. The UE of claim 11, wherein the at least one RRC state comprises a CELL_PCH state or a URA_PCH state.

13. The UE of claim 8, wherein maintaining a count comprises using a counter.

14. The UE of claim 8, wherein said maintaining includes incrementing the count.

15. A tangible, non-transitory computer-readable medium containing instructions which, when executed, cause a computing device to perform operations comprising:

maintaining a count of signaling connection release indication (SCRI) messages sent by a UE to a network, wherein at least one of the SCRI messages comprises a transition indicator;

entering radio resource control (RRC) Connected mode; and

after entering the RRC Connected mode, resetting the count of SCRI messages.

16. The tangible, non-transitory computer-readable medium of claim 15, wherein the SCRI messages sent by the UE each has a cause set.

17. The tangible, non-transitory computer-readable medium of claim 16, wherein the cause is set to UE Requested PS Data session end.

18. The tangible, non-transitory computer-readable medium of claim 15, wherein the SCRI messages are sent by the UE while in at least one radio resource control (RRC) state.

19. The tangible, non-transitory computer-readable medium of claim 18, wherein the at least one RRC state comprises a CELL_PCH state or a URA_PCH state.

20. The tangible, non-transitory computer-readable medium of claim 15, wherein maintaining a count comprises using a counter.
