Abstract

The present invention provides a method for providing route update messages paging access terminals. The method may include providing at least one route update message based upon at least one travel pattern associated with an access terminal. The method may also include providing at least one page based on at least one previously received route update message and information indicative of at least one travel pattern.

Claims

1. A method, comprising:

providing at least one route update message based upon at least one travel pattern associated with an access terminal.

2. The method of claim 1, wherein providing said at least one route update message comprises associating the access terminal with said at least one travel pattern.

3. The method of claim 2, wherein associating the access terminal with said at least one travel pattern comprises associating the access terminal with said at least one travel pattern based on at least one cell visited by the access terminal.

4. The method of claim 1, wherein providing said at least one route update message comprises providing at least one route update message in response to the access terminal entering at least one cell not included in said at least one travel pattern.

5. The method of claim 1, wherein providing said at least one route update message comprises providing at least one route update message in response to the access terminal entering at least one cell included in said at least one travel pattern when a route update message associated with said at least one travel pattern has not been provided.

6. The method of claim 1, comprising providing at least one route update message in response to the access terminal entering at least one cell that is further than a predetermined radius from a cell received a previous route update message.

7. The method of claim 1, comprising determining, at the access terminal, said at least one travel pattern.

8. The method of claim 7, wherein determining said at least one travel pattern comprises determining at least one primary cell based on at least one likelihood that the access terminal is present in said at least one primary cell.

9. The method of claim 8, wherein determining said at least one travel pattern comprises determining at least one cell visited by the access terminal after leaving said at least one primary cell and until returning to said at least one primary cell.

10. The method of claim 9, wherein determining said at least one travel pattern comprises associating said at least one cell with said at least one travel pattern based on a correlation metric.

11. The method of claim 7, comprising providing information indicative of said at least one travel pattern to at least one access network.

12. The method of claim 7, comprising dropping at least one of a cell and a travel pattern based on a probability the cell or travel pattern has been visited by an access terminal.

13. The method of claim 1, comprising receiving at least one paging message broadcast to cells associated with said at least one travel pattern.

14. A method, comprising:

receiving at least one route update message that is provided based upon at least one travel pattern associated with an access terminal.

15. The method of claim 14, wherein receiving said at least one route update message based upon said at least one travel pattern comprises receiving said at least one route update message transmitted based upon at least one travel pattern associated with the access terminal based on at least one cell visited by the access terminal.

16. The method of claim 14, wherein receiving said at least one route update message comprises receiving at least one route update message in response to the access terminal entering at least one cell not included in said at least one travel pattern.

17. The method of claim 14, wherein receiving said at least one route update message comprises receiving at least one route update message in response to the access terminal entering at least one cell included in said at least one travel pattern when a route update message associated with said at least one travel pattern has not been provided.

18. The method of claim 14, comprising receiving at least one route update message in response to the access terminal entering at least one cell that is further than a predetermined radius from a cell received the last route update message.

19. The method of claim 14, wherein receiving said at least one route update message based upon said at least one travel pattern comprises receiving said at least one route update message based upon at least one travel pattern determined at the access terminal.

20. The method of claim 14, comprising receiving information indicative of said at least one travel pattern.

21. The method of claim 14, comprising receiving information that at least one of a cell and a travel pattern should be dropped based on a probability the cell or travel pattern has been visited by an access terminal.

22. The method of claim 14, comprising providing at least one paging message to cells associated with said at least one travel pattern.

23. A method, comprising:

providing at least one page based on at least one previously received route update message and information indicative of at least one travel pattern.

24. The method of claim 23, wherein providing said at least page comprises providing said at least one page intended for an access terminal based upon a route update message received from the access terminal and at least one travel pattern associated with the access terminal.

25. The method of claim 23, wherein providing said at least one page comprises providing said at least one page to at least one cell in said at least one travel pattern.

26. The method of claim 25, wherein providing said at least one page to at least one cell in said at least one travel pattern comprises providing said at least one page to at least one cell in said at least one travel pattern in response to determining that the previously received route update message was received at a cell included in said at least one travel pattern.

27. The method of claim 23, wherein providing said at least one page comprises providing said at least one page to at least one primary cell.

28. The method of claim 27, wherein providing said at least one page to at least one primary cell comprises providing said at least one page to said at least one primary cell in response to determining that the previously received route update message was received at the primary cell.
