Enhanced voice pre-emption of active packet data service
View Patent ↗A method in wireless communication devices, for example, a cellular handset, including receiving a network control message, forcing an active packet session into a dormancy state in response to receiving the network control message, suspending a dormancy timer after receiving the network control message, and starting the dormancy timer upon completion of an event, for example, a voice pre-emption, that precipitated suspension of the active packet session.
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 either 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 either 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:
receiving a network control message;
suspending an active packet session of the wireless communication device in response to receiving the network control message;
suspending a dormancy timer after receiving the network control message.
14. 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.
15. The method of claim 13 , suspending the dormancy timer includes suspending initiation of the dormancy timer otherwise started upon suspending the active packet session.
16. The method of claim 13 , suspending the dormancy timer includes suspending operation of a dormancy timer after the dormancy timer has started.
17. The method of claim 13 , starting the dormancy timer upon completion of an event precipitating the suspension of the active packet session.
