Abstract

Various methods and devices are provided to address the need to reduce paging latency. In one method, a wireless network determines ( 201 ) that a page for a mobile needs to be transmitted over a target broadcast area. The wireless network schedules ( 202 ) the transmission of the page in an upcoming paging timeslot based on the target broadcast area and then pages ( 203 ) the mobile in the target broadcast area before transmitting an earlier scheduled page for another mobile with a different target broadcast area.

Claims (25)

1. A method for improved paging, the method comprising:

determining, by a wireless network, that a page for a mobile needs to be transmitted over a target broadcast area;

scheduling, by the wireless network, the transmission of the page in an upcoming paging timeslot based on the target broadcast area;

paging, by the wireless network, the mobile in the target broadcast area before transmitting an earlier scheduled page for another mobile with a different target broadcast area;

transmitting pages using a paging queue in First-In-First-Out (FIFO) order except when a later-queued page can be transmitted before an earlier-queued page based on a target broadcast area of the later-queued page.

2. The method as recited in claim 1 , wherein scheduling the transmission of the page in the upcoming paging timeslot based on the target broadcast area comprises

determining, by the wireless network, that the target broadcast area does not overlap with a target broadcast area of any other pages scheduled in the upcoming paging timeslot.

3. The method as recited in claim 2 , wherein the different target broadcast area of the earlier scheduled page does overlap with a target broadcast area of another page scheduled in the upcoming paging timeslot.

4. The method as recited in claim 1 , wherein transmitting pages using a paging queue in FIFO order except when a later-queued page can be transmitted before an earlier-queued page comprises

determining, by the wireless network, that the target broadcast area of the later-queued page does not overlap with a target broadcast area of any other pages scheduled in the same paging timeslot as the later-queued page.

5. The method as recited in claim 4 , wherein the target broadcast area of the earlier-queued page does overlap with a target broadcast area of another page scheduled in the same paging timeslot as the later-queued page.

6. The method as recited in claim 1 , wherein the transmission of the earlier-queued page is not delayed by transmitting the later-queued page before the earlier-queued page.

7. An article of manufacture comprising a non-transitory processor-readable storage medium storing one or more software programs which when executed by one or more processors performs the steps of the method of claim 1 .

8. Wireless network equipment in a communication system, the wireless network equipment being configured to communicate with other devices in the system, wherein the wireless network equipment is operative

to determine that a page for a mobile needs to be transmitted over a target broadcast area,

to schedule the transmission of the page in an upcoming paging timeslot based on the target broadcast area,

to page the mobile in the target broadcast area before transmitting an earlier scheduled page for another mobile with a different target broadcast area, and

to transmit pages using a paging queue in First-In-First-Out (FIFO) order except when a later-queued page can be transmitted before an earlier-queued page based on a target broadcast area of the later-queued page.

9. The wireless network equipment as recited in claim 8 , wherein being operative to schedule the transmission of the page in the upcoming paging timeslot based on the target broadcast area comprises being operative

to determine that the target broadcast area does not overlap with a target broadcast area of any other pages scheduled in the upcoming paging timeslot.

10. The wireless network equipment as recited in claim 9 , wherein the different target broadcast area of the earlier scheduled page does overlap with a target broadcast area of another page scheduled in the upcoming paging timeslot.

11. The wireless network equipment as recited in claim 8 , wherein being operative to transmit pages using a paging queue in FIFO order except when a later-queued page can be transmitted before an earlier-queued page comprises being operative

to determine that the target broadcast area of the later-queued page does not overlap with a target broadcast area of any other pages scheduled in the same paging timeslot as the later-queued page.

12. The wireless network equipment as recited in claim 11 , wherein the target broadcast area of the earlier-queued page does overlap with a target broadcast area of another page scheduled in the same paging timeslot as the later-queued page.

13. The wireless network equipment as recited in claim 8 , wherein the transmission of the earlier-queued page is not delayed by transmitting the later-queued page before the earlier-queued page.
