Abstract

Systems and methods for optimizing paging cycles in a wireless communication system are disclosed. An access terminal can include logic configured to determine an optimal paging cycle and logic configured to set the paging cycle based on the optimal paging cycle, where the paging cycle varies based on at least one optimizing metric.

Claims

1. A method comprising:

determining an optimal paging cycle; and

setting a paging cycle of an access terminal based on the optimal paging cycle, wherein the optimal paging cycle varies over time based on at least one optimizing metric.

2. The method of claim 1, wherein the at least one optimizing metric is at least one of a time of day, call arrival statistics, user profile, type of communication received, or available energy reserve.

3. The method of claim 1, wherein determining the optimal paging cycle comprises:

determining a time of day; and

setting the optimal paging cycle based on the time of day.

4. The method of claim 3, further comprising:

evaluating performance of the optimal paging cycle; and

adjusting the optimal paging cycle, if the performance falls below a threshold.

5. The method of claim 4, wherein the performance is evaluated based on call arrival statistics.

6. The method of claim 5, wherein the threshold is that 95 percent of mobile-terminated calls arrive when the access terminal is operating at a 213 ms paging cycle.

7. The method of claim 1, wherein determining the optimal paging cycle comprises:

collecting call arrival statistics; and

setting the optimal paging cycle based on the call arrival statistics.

8. The method of claim 7, wherein the call arrival statistics are determined at the access terminal.

9. The method of claim 1, further comprising:

setting the optimal paging cycle to an increased duration, if an available energy reserve falls below a threshold value.

10. The method of claim 1, wherein determining the optimal paging cycle comprises:

registering the access terminal at an application server; and

setting the optimal paging cycle based on a user profile stored for the access terminal.

11. The method of claim 1, wherein setting the paging cycle of the access terminal comprises:

generating a paging cycle request in an application to update the paging cycle;

processing the paging cycle request in an application programming interface for adjusting the paging cycle;

transmitting the paging cycle request to an access network in communication with the access terminal;

receiving a request acceptance from the access network; and

forwarding the request acceptance to the application.

12. The method of claim 1, wherein determining the optimal paging cycle comprises:

setting a reduced paging cycle based on a scheduled event.

13. The method of claim 12, wherein the reduced paging cycle is automatically set before the scheduled event based on information saved on the access terminal.

14. The method of claim 1, wherein determining the optimal paging cycle comprises:

setting a reduced paging cycle based on a type of communication received.

15. The method of claim 14, wherein the type of communication received is a push-to-talk call.

16. An apparatus comprising:

logic configured to determine an optimal paging cycle; and

logic configured to set a paging cycle on an access terminal based on the optimal paging cycle, wherein the optimal paging cycle varies over time based on at least one optimizing metric.
