Abstract

Polling performed by multiple applications running on a device is coordinated. A central scheduling function can, for example, periodically issue polling event messages to the applications. The applications can, in turn, request the transmission of polling signals to their respective servers to request application updates. By coordinating transmission of polling signals battery consumption and network communication resources can be optimized.

Claims

1. A method for polling servers from a device comprising:

receiving, at multiple applications which are running simultaneously on the device, a polling event message; and

transmitting, in response to the polling event message, a plurality of polling signals from the device, said polling signals being associated with said multiple applications which received said polling event message.

2. The method of claim 1, wherein each of said polling signals requests updated data or events from servers which each correspond to respective ones of said multiple applications.

3. The method of claim 1, further comprising:

subscribing, by said multiple applications, to a polling signal scheduling service provided by a central scheduling function.

4. The method of claim 3, wherein said step of subscribing further comprises:

sending a subscription message, from each of said multiple applications to said central scheduling function which is operating on said device, said subscription message requesting receipt of said polling event message.

5. The method of claim 4, wherein said subscription message includes information associated with a periodicity at which a respective application requests to receive said polling event message.

6. The method of claim 1, further comprising:

determining a periodicity at which to send said polling event message to said multiple applications.

7. The method of claim 5, further comprising:

determining a periodicity at which to send said polling event message to said multiple applications based upon said information associated with said periodicity at which said respective application requests to receive said polling event message.

8. The method of claim 7, wherein said periodicity is determined based on one of:

(1) an average of said periodicity at which each of said respective applications requests to receive said polling event message;

(2) a weighted average of said periodicity at which each of said respective applications requests to receive said polling event message, (3) a least frequent preferred periodicity, and (4) a most frequent preferred periodicity.

9. The method of claim 1, wherein said device includes a wireless transceiver, and said step of transmitting further comprises:

exiting, by said wireless transceiver, a low power sleep mode; and

transmitting said polling signal for each of said multiple applications during a time interval prior to re-entering said low power sleep mode.

10. The method of claim 9, further comprising:

disabling a central scheduling function which generates said polling event message when said device is in said low power sleep mode.

11. The method of claim 9, further comprising:

informing said central scheduling function that said wireless transceiver has exited said low power sleep mode; and

sending said polling event message to said multiple applications even if a timer which determines when to send said polling event message has not yet expired.

12. The method of claim 1, wherein said polling event message is broadcast to said multiple applications at the same time.

13. The method of claim 1, wherein said polling event message is sent to each of said multiple applications individually.

14. The method of claim 1, wherein said polling event message is sent to said multiple applications in two or more groups separated in time from one another.

15. A device comprising:

a processor configured to simultaneously execute multiple applications each of which periodically receive updates from respective servers and to execute a central scheduling function which periodically transmits a polling event message to said multiple applications; and

a communication interface configured to transmit, in response to the polling event message, a plurality of polling signals from the device, said polling signals being associated with said multiple applications which received said polling event message.

16. The device of claim 15, wherein said multiple applications are configured to subscribe to said central scheduling function by sending a subscription message, from each of said multiple applications to said central scheduling function which is operating on said device, wherein said subscription message requests receipt of said polling event message.

17. The device of claim 16, wherein said subscription message includes information associated with a periodicity at which a respective application requests to receive said polling event message.

18. The device of claim 15, wherein said central scheduling function is further configured to determine a periodicity at which to send said polling event message to said multiple applications.

19. The device of claim 18, wherein said central scheduling function is further configured to determine a periodicity at which to send said polling event message to said multiple applications based upon said information associated with said periodicity at which said respective application requests to receive said polling event message.

20. The device of claim 19, wherein said periodicity is determined based on one of:

(1) an average of said periodicity at which each of said respective applications requests to receive said polling event message, (2) a weighted average of said periodicity at which each of said respective applications requests to receive said polling event message, (3) a least frequent preferred periodicity, and (4) a most frequent preferred periodicity.

21. The device of claim 15, wherein said communication interface includes a wireless transceiver, and said wireless transceiver is further configured to exit a low power sleep mode, and to transmit said polling signal for each of said multiple applications during a time interval prior to re-entering said low power sleep mode.

22. The device of claim 21, wherein said processor is further configured to disable said central scheduling function which generates said polling event message when said device is in said low power sleep mode.

23. The device of claim 21, wherein said processor is further configured to inform said central scheduling function that said wireless transceiver has exited said low power sleep mode, and wherein said central scheduling function is further configured to send said polling event message to said multiple applications even if a timer which determines when to send said polling event message has not yet expired.

24. The device of claim 15, wherein said polling event message is broadcast to said multiple applications at the same time.

25. The device of claim 15, wherein said polling event message is sent to each of said multiple applications individually.

26. The device of claim 15, wherein said polling event message is sent to said multiple applications in two or more groups separated in time from one another.

27. The device of claim 15, further comprising:

a user interface which enables a user of said device to control parameters associated with said central scheduling function.

28. The device of claim 27, wherein said user interface is further configured to display information regarding how controlling polling signals associated with applications which are not currently subscribed to said central scheduling function will impact power consumption by said device.
