Abstract

The disclosed embodiments provide for methods and systems for monitoring a paging channel. In one aspect, a method for monitoring a paging channel includes monitoring a paging channel for a page message at scheduled paging slots, determining that an error has occurred at a given paging slot, and monitoring the paging channel for a re-page message at at least one scheduled re-paging slot, where the re-paging slots occur after the given paging slot but before the next scheduled paging slot. In another aspect, a method for monitoring a paging channel includes monitoring a first one of a plurality of paging channels for a page message at scheduled paging slots, determining that an error has occurred at a given paging slot, and monitoring at least a second one of the plurality of paging channels for the page message.

Claims

1. A method for monitoring a paging channel, the method comprising:

monitoring a paging channel for a page message at scheduled paging slots;

determining that an error has occurred at a given paging slot; and

monitoring the paging channel for a re-page message at at least one scheduled re-paging slot, the at least one re-paging slot occurring after the given paging slot but before the next scheduled paging slot.

2. The method of claim 1, wherein the re-page message is communicated based on detecting the error.

3. The method of claim 2, wherein the error indicates that the page message was not successfully received at the given paging slot.

4. A method for paging a target access terminal (AT), the method comprising:

sending a page message directed toward a target access terminal (AT) at scheduled paging slots; and

sending a re-page message directed toward the target AT at a scheduled re-paging slot if an error is detected at a given paging slot, the re-paging slot being after the given paging slot but before the next scheduled paging slot.

5. The method of claim 4, wherein the error is detected when no response is received that the AT has successfully monitored the page message.

6. A method for monitoring a paging channel, the method comprising:

monitoring a first one of a plurality of paging channels for a page message at scheduled paging slots;

determining that an error has occurred at a given paging slot; and

monitoring at least a second one of the plurality of paging channels for the page message.

7. The method of claim 6, wherein the plurality of paging channels are time synchronized.

8. The method of claim 6, wherein the plurality of paging channels are not time synchronized, and a following monitoring of a page message occurs at a following scheduled paging slot on the second channel.

9. A computer-readable medium embodying means for implementing a method for monitoring a paging channel, the method comprising:

monitoring a paging channel for a page message at scheduled paging slots;

determining that an error has occurred at a given paging slot; and

monitoring the paging channel for a re-page message at at least one scheduled re-paging slot, the at least one re-paging slot occurring after the given paging slot but before the next scheduled paging slot.

10. The medium of claim 9, wherein the re-page message is communicated based on detecting the error.

11. The medium of claim 10, wherein the error indicates that the page message was not successfully received at the given paging slot.

12. A computer-readable medium embodying means for implementing a method for paging a target access terminal (AT), the method comprising:

sending a page message directed toward a target access terminal (AT) at scheduled paging slots; and

sending a re-page message directed toward the target AT at a scheduled re-paging slot if an error is detected at a given paging slot, the re-paging slot being after the given paging slot but before the next scheduled paging slot.

13. The medium of claim 12, wherein the error is detected when no response is received that the AT has successfully monitored the page message.

14. A computer-readable medium embodying means for implementing a method for monitoring a paging channel, the method comprising:

monitoring a first one of a plurality of paging channels for a page message at scheduled paging slots;

determining that an error has occurred at a given paging slot; and

monitoring at least a second one of the plurality of paging channels for the page message.

15. The medium of claim 14, wherein the plurality of paging channels are time synchronized.

16. The medium of claim 14, wherein the plurality of paging channels are not time synchronized, and a following monitoring of a page message occurs at a following scheduled paging slot on the second channel.

17. An apparatus for monitoring a paging channel, comprising:

means for monitoring a paging channel for a page message at scheduled paging slots;

means for determining that an error has occurred at a given paging slot; and

means for monitoring the paging channel for a re-page message at at least one scheduled re-paging slot, the at least one re-paging slot occurring after the given paging slot but before the next scheduled paging slot.

18. The apparatus of claim 17, wherein the re-page message is communicated based on detecting the error.

19. The apparatus of claim 18, wherein the error indicates that the page message was not successfully received at the given paging slot.

20. An apparatus for paging a target access terminal (AT), comprising:

means for sending a page message directed toward a target access terminal (AT) at scheduled paging slots; and

means for sending a re-page message directed toward the target AT at a scheduled re-paging slot if an error is detected at a given paging slot, the re-paging slot being after the given paging slot but before the next scheduled paging slot.

21. The apparatus of claim 20, wherein the error is detected when no response is received that the AT has successfully monitored the page message.

22. An apparatus for monitoring a paging channel, comprising:

means for monitoring a first one of a plurality of paging channels for a page message at scheduled paging slots;

means for determining that an error has occurred at a given paging slot; and

means for monitoring at least a second one of the plurality of paging channels for the page message.

23. The apparatus of claim 22 wherein the plurality of paging channels are time synchronized.

24. The apparatus of claim 22, wherein the plurality of paging channels are not time synchronized, and a following monitoring of a page message occurs at a following scheduled paging slot on the second channel.

25. At least one processor configured to implement a method for monitoring a paging channel, the method comprising:

monitoring a paging channel for a page message at scheduled paging slots;

determining that an error has occurred at a given paging slot; and

monitoring the paging channel for a re-page message at at least one scheduled re-paging slot, the at least one re-paging slot occurring after the given paging slot but before the next scheduled paging slot.

26. The processor of claim 25, wherein the re-page message is communicated based on detecting the error.

27. The processor of claim 26, wherein the error indicates that the page message was not successfully received at the given paging slot.

28. At least one processor configured to implement a method for paging a target access terminal (AT), the method comprising:

sending a page message directed toward a target access terminal (AT) at scheduled paging slots; and

sending a re-page message directed toward the target AT at a scheduled re-paging slot if an error is detected at a given paging slot, the re-paging slot being after the given paging slot but before the next scheduled paging slot.

29. The processor of claim 28, wherein the error is detected when no response is received that the AT has successfully monitored the page message.

30. At least one processor configured to implement a method for monitoring a paging channel, the method comprising:

monitoring a first one of a plurality of paging channels for a page message at scheduled paging slots;

determining that an error has occurred at a given paging slot; and

monitoring at least a second one of the plurality of paging channels for the page message.

31. The processor of claim 30, wherein the plurality of paging channels are time synchronized.

32. The processor of claim 30, wherein the plurality of paging channels are not time synchronized, and a following monitoring of a page message occurs at a following scheduled paging slot on the second channel.
