Abstract

A method in a wireless communication system (100) dynamically updates paging gap times (314, 324) associated with a plurality of addresses (312, 322) of at least one wireless device (110) in a two phase paging system included in the wireless communication system (100). The method includes updating a first paging gap time (314) associated with a first address (312) of the at least one wireless device (110) in a two phase paging system, and updating a second paging gap time (324) associated with a second address (322) of the at least one wireless device (110), the second paging gap time (324) being different than the first paging gap time (314).

Claims

1. A method for dynamically updating paging gap times associated with a plurality of addresses of a wireless device in a two phase paging system included in a wireless communication system, wherein the two phase paging system comprises a first phase for transmitting a short paging message and a second phase for transmitting a full paging message wherein the full paging message is transmitted after delay of a paging gap time from the short paging message, the method comprising:

setting a first paging gap time for a first address of the wireless device, the first address being mapped to a first function in the wireless device;

setting a second paging gap time for a second address of the wireless device, the second address being mapped to a second function in the wireless device;

updating the first paging gap time associated with the first address of the wireless device; and

updating a second paging gap time associated with a second address of the wireless device, the second paging gap time being different than the first paging gap time.

2. The method of claim 1, wherein the first address is associated with a PTT function in the wireless device and the second address is associated with a telephony function in the wireless device.

3. The method of claim 2, wherein the wireless device comprises a plurality of wireless devices, and wherein the first address is associated with a PTT function in a first wireless device of the plurality of wireless devices and the second address is associated with a telephony function in a second wireless device of the plurality of wireless devices, the second wireless device being different than the first wireless device.

4. The method of claim 2, wherein the first paging gap time associated with the first address is smaller than the second paging gap time associated with the second address.

5. The method of claim 1, wherein a first paging cycle time is associated with the first address, and wherein the first paging gap time is updated to a first value if the first paging cycle time is greater than a predefined threshold and otherwise the first paging gap time is updated to a second value different than the first value.

6. The method of claim 5, wherein the first value is greater than the second value.

7. The method of claim 1, wherein the updating of the first paging gap time comprises:

transmitting an update message to the wireless device.

8. The method of claim 7, wherein the update message includes at least one page gap time setting criteria.

9. The method of claim 1, wherein the updating of the first paging gap time comprises:

updating a database record, that is associated with the wireless device, with the first paging gap time.

10. The method of claim 1, wherein the first paging gap time is updated to an infinite paging gap time and the second paging gap time is updated to a finite paging gap time, and the first address and the second address are the same.

11. The information processing system of claim 10, wherein the updating of the first paging gap time comprises:

transmitting an update message destined for reception by the wireless device.

12. The information processing system of claim 10, wherein the memory includes a page gap timing data base that includes a plurality of records corresponding to a respective plurality of addresses associated with the wireless device, and wherein the updating of the first paging gap time comprises:

updating a database record, that is associated with the wireless device, with the first paging gap time.

13. An information processing system for dynamically updating paging gap times associated with a plurality of addresses of a wireless device in a two phase paging system included in a wireless communication system, wherein the two phase paging system comprises a first phase for transmitting a short paging message and a second phase for transmitting a full paging message wherein the full paging message is transmitted after delay of a paging gap time from the short paging message, the information processing system comprising:
