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, at a user equipment (UE), a count of signaling connection release indication (SCRI) messages sent by the UE, including incrementing, while in a paging channel state, the count to reflect the UE causing a SCRI message to be sent, each counted SCRI message having a cause set to UE Requested PS (Packet Switched) Data session end;

transmitting signaling by the UE on radio bearer 3 (RB3) or upwards;

resetting the count by the UE responsive to the transmission of signaling;

determining whether a current value of the count is equal to or exceeds a predetermined value; and

responsive to the determination, stopping the sending of further SCRI messages with a cause set to UE Requested PS Data session end.

2. The method of claim 1, wherein the signaling comprises uplink radio link control (RLC) control protocol data units (PDU).

3. The method of claim 1, wherein the paging channel state is a CELL_PCH state or a URA_PCH state.

4. The method of claim 1, further comprising determining whether a current value of the count is less than a predetermined value.

5. The method of claim 4, wherein the predetermined value is 1.

6. The method of claim 1, wherein the predetermined value is 1.

7. A method comprising:

maintaining, at a user equipment (UE), a count of signaling connection release indication (SCRI) messages sent by the UE, including incrementing, while in a paging channel state, the count to reflect the UE causing a SCRI message to be sent, each counted SCRI message having a cause set to UE Requested PS (Packet Switched) Data session end;

transmitting, from the UE to the network, packet switched (PS) data;

resetting the count by the UE responsive to transmitting the PS data;

determining whether a current value of the count is equal to or exceeds a predetermined value; and

responsive to the determination, stopping the sending of further SCRI messages with a cause set to UE Requested PS Data session end.

8. The method of claim 7, further comprising:

transmitting signaling by the UE on radio bearer 3 (RB3) or upwards, wherein the signaling comprises uplink radio link control (RLC) control protocol data units (PDU).

9. The method of claim 7, wherein the paging channel state is one of a CELL_PCH state or a URA_PCH state.

10. The method of claim 7, further comprising determining whether a current value of the count is less than a predetermined value.

11. The method of claim 10, wherein the predetermined value is 1.

12. The method of claim 7, wherein the predetermined value is 1.

13. A user equipment (UE) comprising a processor, configured to:

maintain a count of signaling connection release indication (SCRI) messages sent by the UE, including incrementing, while in a paging channel state, the count to reflect the UE causing a SCRI message to be sent, each counted SCRI message having a cause set to UE Requested PS (Packet Switched) Data session end;

transmit signaling on radio bearer 3 (RB3) or upwards;

reset the count responsive to the transmission of signaling;

determine whether a current value of the count is equal to or exceeds a predetermined value; and

responsive to the determination, stop the sending of further SCRI messages with a cause set to UE Requested PS Data session end.

14. The UE of claim 13, wherein the signaling comprises uplink radio link control (RLC) control protocol data units (PDU).

15. The UE of claim 13, wherein the paging channel state is a CELL_PCH state or a URA_PCH state.

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

17. The UE of claim 13, wherein the processor is further configured to determine whether a current value of the count is less than a predetermined value.

18. The UE of claim 17, wherein the predetermined value is 1.

19. The UE of claim 13, wherein the predetermined value is 1.

20. A user equipment (UE) comprising a processor, configured to:

maintain a count of signaling connection release indication (SCRI) messages sent by the UE, including incrementing, while in a paging channel state, the count to reflect the UE causing a SCRI message to be sent, each counted SCRI message having a cause set to UE Requested PS (Packet Switched) Data session end;

transmit, to the network, PS data;

reset the count responsive to transmitting the PS data;

determine whether a current value of the count is equal to or exceeds a predetermined value; and

responsive to the determination, stop the sending of further SCRI messages with a cause set to UE Requested PS Data session end.

21. The UE of claim 20, wherein the processor is further configured to transmit signaling on radio bearer 3 (RB3) or upwards, wherein the signaling comprises uplink radio link control (RLC) control protocol data units (PDU).

23. The UE of claim 20, wherein maintaining a count comprises using a counter.

24. The UE of claim 20, wherein the processor is further configured to determine whether a current value of the count is less than a predetermined value.

25. The UE of claim 24, wherein the predetermined value is 1.

26. The UE of claim 20, wherein the predetermined value is 1.

27. A user equipment (UE) comprising a processor, configured to:
