Abstract

Methods in wireless communications devices, for example, cellular handsets, including receiving a network control message (224), forcing an active packet session into a dormancy state in response to receiving the network control message (226), suspending a dormancy timer after receiving the network control message (230), and starting the dormancy timer upon completion of an event, for example, a voice preemption, that precipitated suspension of the active packet session.

Claims

1. A method in a wireless communications device, the method comprising:

pre-empting an active packet session with an event;

suspending operation of a dormancy timer initiated upon pre-emption of the active packet session;

re-starting the suspended dormancy timer upon completion of one of a service or application associated with the event pre-empting the active packet session.

2. The method of claim 1, resuming the pre-empted packet session upon expiration of the dormancy timer after re-starting the dormancy timer.

3. The method of claim 1, receiving a network control message with dormancy timer information before suspending the dormancy timer.

4. The method of claim 3, starting the dormancy timer after receiving the network control message.

5. The method of claim 1,

pre-empting the active packet session with a pending voice call;

re-starting the suspended dormancy timer upon completion of the voice call associated with pre-empting the packet session.

6. The method of claim 5, receiving a page, conducting the voice call after receiving the page.

7. A method in a wireless communications device, the method comprising:

pre-empting an active packet session with an event;

suspending initiation of a dormancy timer that would otherwise be initiated after pre-emption of the packet session;

initiating the suspended dormancy timer upon completion of one of a service or application associated with the event pre-empting the active packet session.

8. The method of claim 7, resuming the pre-empted packet session upon expiration of the dormancy timer initiated upon completion of the service or application associated with the event pre-empting the active packet session.

9. The method of claim 7, receiving a network control message with dormancy timer information before suspending the dormancy timer.

10. The method of claim 9, starting the dormancy timer after receiving the network control message.

11. The method of claim 7,

pre-empting the active packet session with a pending voice call;

re-starting the suspended dormancy timer upon completion of the voice call associated with pre-empting the packet session.

12. The method of claim 11, receiving a page, conducting the voice call after receiving the page.

13. A method in a wireless communications device, the method comprising:

suspending an active packet session of the wireless communication device;

suspending a dormancy timer after receiving the network control message.

14. The method of claim 13,

receiving a network control message,

suspending the active packet session of the wireless communication device in response to receiving the network control message.

15. The method of claim 13,

receiving a page after receiving the network control message,

conducting a voice call after receiving the page, and

resuming the suspended dormancy timer after completing the voice call.

16. The method of claim 13, suspending the dormancy timer includes suspending initiation of the dormancy timer otherwise started upon suspending the active packet session.

17. The method of claim 13, suspending the dormancy timer includes suspending operation of a dormancy timer after the dormancy timer has stared.

18. The method of claim 13,

starting the dormancy timer upon completion of an event precipitating the suspension of the active packet session.
