Abstract

A method of handling a transferring from an energy-consuming mode to an energy-saving mode for a communication device in a wireless communication system is disclosed. The method comprises transmitting or receiving a first message of an upper protocol layer; deferring the transferring, if the communication device determines that a second message of the upper protocol layer corresponding to the first message is going to be transmitted or received; and advancing the transferring, if the communication device determines that no message corresponding to the first message is going to be transmitted or received.

Claims

1. A method of handling a transferring from an energy-consuming mode to an energy-saving mode for a communication device in a wireless communication system, the method comprising:

transmitting or receiving a first message of an upper protocol layer;

deferring the transferring, if the communication device determines that a second message of the upper protocol layer corresponding to the first message is going to be transmitted or received; and

advancing the transferring, if the communication device determines that no message corresponding to the first message is going to be transmitted or received.

2. The method of claim 1, wherein the transferring is performed by the communication device at a lower protocol layer comprising at least one of a physical layer and a medium access control (MAC) layer.

3. The method of claim 1, wherein the communication device defers the transferring by increasing a value of an inactivity timer, and advances the transferring by decreasing the value of the inactivity timer.

4. The method of claim 1, wherein the upper protocol layer is a transport layer or an application layer.

5. The method of claim 4, wherein the first message is a transmission control protocol (TCP) message, a session initiation protocol (SIP) message, a domain name system (DNS) query message or a hypertext transfer protocol (HTTP) message.

6. The method of claim 1, wherein the communication device determines that no message corresponding to the first message is going to be transmitted or received, when the first message is an ending message in a procedure.

7. The method of claim 1, wherein the communication device determines that the second message corresponding to the first message is going to be transmitted or received, when the first message is an initial message triggering at least one successive message.

8. A method of handling a transferring from an energy-consuming mode to an energy-saving mode for a communication device in a wireless communication system, the method comprising:

performing a first session of an upper protocol layer;

deferring the transferring, if the communication device determines that a second session of the upper protocol layer corresponding to the first session is going to be performed; and

advancing the transferring, if the communication device determines that no session corresponding to the first session is going to be performed.

9. The method of claim 8, wherein the transferring is performed by the communication device at a lower protocol layer comprising at least one of a physical layer and a medium access control (MAC) layer.

10. The method of claim 8, wherein the communication device defers the transferring by increasing a value of an inactivity timer, and advances the transferring by decreasing the value of the inactivity timer.

11. The method of claim 8, wherein the upper protocol layer is a transport layer or an application layer.

12. The method of claim 11, wherein the first session is a transmission control protocol (TCP) session, a session initiation protocol (SIP) session, a domain name system (DNS) session or a hypertext transfer protocol (HTTP) session.

13. The method of claim 8, wherein the communication device determines that no session corresponding to the first session is going to be performed, when the first session is an ending session.

14. The method of claim 8, wherein the communication device determines that the second session corresponding to the first session is going to be performed, when the first session is an initial session triggering at least one successive session.

15. A communication device in a wireless communication system for handling a transferring from an energy-consuming mode to an energy-saving mode, the communication device comprising:

means for transmitting or receiving a first message of an upper protocol layer;

means for deferring the transferring, if the communication device determines that a second message of the upper protocol layer corresponding to the first message is going to be transmitted or received; and

means for advancing the transferring, if the communication device determines that no message corresponding to the first message is going to be transmitted or received.

16. The communication device of claim 15, wherein the transferring is performed by the communication device at a lower protocol layer comprising at least one of a physical layer and a medium access control (MAC) layer.

17. The communication device of claim 15, wherein the communication device defers the transferring by increasing a value of an inactivity timer, and advances the transferring by decreasing the value of the inactivity timer.

18. The communication device of claim 15, wherein the upper protocol layer is a transport layer or an application layer.

19. The communication device of claim 18, wherein the first message is a transmission control protocol (TCP) message, a session initiation protocol (SIP) message, a domain name system (DNS) query message or a hypertext transfer protocol (HTTP) message.

20. The communication device of claim 15, wherein the communication device determines that no message corresponding to the first message is going to be transmitted or received, when the first message is an ending message in a procedure.

21. The communication device of claim 15, wherein the communication device determines that the second message corresponding to the first message is going to be transmitted or received, when the first message is an initial message triggering at least one successive message.

22. A communication device in a wireless communication system for handling a transferring from an energy-consuming mode to an energy-saving mode, the communication device comprising:

means for performing a first session of an upper protocol layer;

means for deferring the transferring, if the communication device determines that a second session of the upper protocol layer corresponding to the first session is going to be performed; and

means for advancing the transferring, if the communication device determines that no session corresponding to the first session is going to be performed.

23. The communication device of claim 22, wherein the transferring is performed by the communication device at a lower protocol layer comprising at least one of a physical layer and a medium access control (MAC) layer.

24. The communication device of claim 22, wherein the communication device defers the transferring by increasing a value of an inactivity timer, and advances the transferring by decreasing the value of the inactivity timer.

25. The communication device of claim 22, wherein the upper protocol layer is a transport layer or an application layer.

26. The communication device of claim 25, wherein the first session is a transmission control protocol (TCP) session, a session initiation protocol (SIP) session, a domain name system (DNS) session or a hypertext transfer protocol (HTTP) session.

27. The communication device of claim 22, wherein the communication device determines that no session corresponding to the first session is going to be performed, when the first session is an ending session.

28. The communication device of claim 22, wherein the communication device determines that the second session corresponding to the first session is going to be performed, when the first session is an initial session triggering at least one successive session.
