Abstract

A method and apparatus for sending an event from user equipment operating in a mobile network, the method comprising the steps of: monitoring whether an unrelated opportunistic event has occurred; and sending said event with said unrelated opportunistic event.

Claims

1. A method for sending an event from user equipment operating in a mobile network, the method comprising the steps of:

monitoring whether an unrelated opportunistic event has occurred; and

sending said event with said unrelated opportunistic event.

2. The method of claim 1, wherein said event is a periodic event.

3. The method of claim 2, wherein said method further includes the steps of:

setting an event timer; and

transmitting said periodic event if said monitoring step does not find an unrelated opportunistic event has occurred prior to the expiration of the event timer.

4. The method of claim 3, wherein said method further includes the step of resetting the event timer after said sending or said transmitting steps.

5. The method of claim 2 further comprising the step of checking whether the time elapsed since a previous event was sent to the network exceeds a threshold, said checking step occurring after said monitoring step detects a network connection and before the sending step, said checking step blocking said sending step if the time elapsed is below the threshold.

6. The method of claim 2, wherein said event is a keep alive message.

7. The method of claim 1, wherein said event is an automated real time event.

8. The method of claim 7, wherein said method further includes the steps of:

setting a maximum delay timer; and

transmitting said automated real time event upon the expiration of said maximum delay timer, wherein said transmitting step occurs if said monitoring step does not detect an opportunistic event.

9. The method of claim 8, further comprising the step of resetting said maximum delay timer after said sending or transmitting steps.

10. The method of claim 1, wherein the opportunistic event is an asynchronous event.

11. The method of claim 10, wherein the asynchronous event is one of an email or other application level message, a voice call and a short/multimedia message service being sent or received by the user equipment.

12. The method of claim 1, wherein the opportunistic event is the connection of the user equipment to a charger.

13. The method of claim 1, wherein the mobile network is one of a UMTS network,

14. The method of claim 13, wherein if the mobile network is the UMTS network, the sending step prevents an extra network connection to a Cell_DCH or Cell_FACH state.

15. Always-on user equipment in a mobile network adapted for sending an event, the user equipment having a radio subsystem including a radio adapted to communicate with the mobile network;

a radio processor having a digital signal processor and adapted to interact with said radio subsystem;

memory;

a user interface;

a processor adapted to run user applications and interact with the memory, the radio and the user interface and adapted to run applications, the user equipment characterized by having means for;

monitoring whether an unrelated opportunistic event has occurred; and

sending said event with said unrelated opportunistic event.

16. The user equipment of claim 15, wherein the mobile network is one of a GPRS network, a CDMA network and a UMTS network.

17. The user equipment of claim 15, wherein the opportunistic event detected by the means for monitoring is caused by a protocol message being sent from the user equipment.

18. The user equipment of claim 17, wherein the protocol message is one of a routing area update, a location area update, or a universal terrestrial radio access network area update.

19. The user equipment of claim 15, wherein the opportunistic event detected by the means for monitoring is caused by one of an email or other application level message, a voice call and a short/multimedia message service being sent or received by the user equipment.

20. The user equipment of claim 15, wherein the means for monitoring is adapted to monitor whether the user equipment is connected to a charger, and if yes, the means for monitoring is adapted to send the message to the network.

21. The user equipment of claim 15, further characterized by means for:

setting an event timer; and

transmitting said event if said monitoring means does not find an unrelated opportunistic event has occurred prior to the expiration of the event timer.

22. The user equipment of claim 21, further characterized by means for checking whether the time elapsed since a previous event was sent to a presence agent exceeds a threshold, said means for checking adapted to block the sending of the message and resetting of the timer is the time elapsed is below the threshold.

23. The user equipment of claim 15, wherein said event is an automated real time event.

24. The user equipment of claim 23, further characterized by means for:

setting a maximum delay timer; and

transmitting said automated real time event upon the expiration of said maximum delay timer, wherein said transmitting means transmits if said monitoring means does not detect an opportunistic event.

25. The user equipment of claim 24, further comprising means for resetting said maximum delay timer.

26. The user equipment of claim 15, wherein the opportunistic event is an asynchronous event.
