Abstract

A paging controller to compute idle mode parameters associated with a first mobile station of at least one set of mobile stations located in a first paging group. The at least one set of mobile stations including the first mobile station and at least a second mobile station. The paging controller is to synchronize an upcoming mobile station paging listening interval for the at least one set of mobile stations.

Claims

1. An apparatus, comprising a paging controller to compute idle mode parameters associated with a first mobile station of at least one set of mobile stations located in a first paging group, said at least one set of mobile stations comprising said first mobile station and at least a second mobile station, and said paging controller to synchronize an upcoming mobile station paging listening interval for said at least one set of mobile stations.

2. The apparatus of claim 1, wherein said at least one set of mobile stations is characterized by timeslot parameters T and Δ

T, wherein T is a time instant marking the start of a paging interval for said at least one set of mobile stations, and wherein Δ

T is the duration of said upcoming mobile station paging listening interval for said at least one set of mobile stations.

3. The apparatus of claim 1, wherein said paging controller is to compute said idle mode parameters associated with multiple mobile stations located in said first paging group.

4. The apparatus of claim 1, wherein said paging controller is to dynamically compute said at least one set of mobile stations maintained in said paging controller prior to said upcoming mobile station paging listening interval for said at least one set of mobile stations.

5. The apparatus of claim 4, wherein said paging controller is to compute said idle mode parameters associated with said at least one set of mobile stations maintained in said paging controller based on a trigger.

6. The apparatus of claim 5, wherein said trigger is aperiodic, wherein said aperiodic trigger is generated when an idle mode mobile station enters or exits said first paging group;

or when an idle mode mobile station exits idle mode and enter active mode;

or when a packet is received for an idle mode mobile station.

7. The apparatus of claim 5, wherein said trigger is periodic, wherein said period trigger is computed by said paging controller to provision sufficient time to transmit a backbone message to a base station and to schedule a downlink to said at least one set of mobile stations.

8. The apparatus of claim 1, wherein said paging controller is to construct inputs for a paging message to be transmitted to a base station, said paging message comprising information to identify said at least one set of mobile stations to be paged at said synchronized upcoming mobile station paging listening interval.

9. The apparatus of claim 9, wherein said information comprising said timeslot parameters T and Δ

T and multiple mobile station media access control addresses associated with each of said mobile stations in said at least one set of mobile stations.

10. An apparatus comprising a processor to receive a first message from a paging controller, said first message comprising identification information to identify at least one set of mobile stations located in a paging group and an upcoming mobile station paging listening interval, wherein said upcoming mobile station paging listening interval is synchronized to said at least one set of mobile stations.

11. The apparatus of claim 10, wherein said processor is to schedule transmission of a second message on downlink to said set of mobile stations located in said paging group.

12. The apparatus of claim 11, wherein said processor is to transmit said second message within said synchronized paging listening interval that is common to a listening interval of each mobile station within said set of mobile stations.

13. The apparatus of claim 10, wherein said processor is to transmit said second message when each one of said mobile stations in said set of mobile stations are scheduled to receive incoming packets.

14. An apparatus comprising:

a first mobile station comprising a processor to receive a message from a base station within a synchronized mobile station paging listening interval associated with a first set of mobile stations located in a paging group, said first set of mobile stations comprising said first mobile station, and said message comprising information associated with a paging listening interval of said first mobile station.

15. The apparatus of claim 15, wherein said first paging listening interval of said first mobile station is synchronized with a paging listening interval of a second mobile station within said first set of mobile stations located in said paging group.

16. A system, comprising:

an antenna; and

a paging controller to compute idle mode parameters associated with a first mobile station of at least one set of mobile stations located in a first paging group, said at least one set of mobile stations comprising said first mobile station and least a second mobile station, and said paging controller to synchronize an upcoming mobile station paging listening interval for said at least one set of mobile stations.

17. The system of claim 16, wherein said at least one set of mobile stations is characterized by timeslot parameters T and Δ

T, wherein T is a time instant marking the start of a paging interval for said at least one set of mobile stations, and wherein Δ

T is the duration of said upcoming mobile station paging listening interval for said at least one set of mobile stations.

18. The system of claim 16, wherein said paging controller is to compute idle mode parameters associated with multiple mobile stations located in said first paging group among multiple sets of mobile stations.

19. The system of claim 16, wherein said paging controller is to dynamically compute said at least one set of mobile stations maintained in said paging controller prior to said upcoming mobile station paging listening interval for said at least one set of mobile stations.

20. The apparatus of claim 16, wherein said paging controller is to construct inputs for a paging message to be transmitted to a base station, said paging message comprising information to identify said least one set of mobile stations to be paged at said synchronized upcoming mobile station paging listening interval.

21. A method comprising:

determining idle mode parameters associated with a first mobile station located in a paging group;

computing at least a first set of mobile stations comprising said first mobile station and at least a second mobile station based on said idle mode parameters; and

constructing a message to be transmitted to said set of mobile stations, said message comprising information to identify said at least one set of mobile stations to be paged at an upcoming mobile station paging listening interval, wherein said upcoming mobile station paging listening interval is synchronized between said first and second mobile station.

22. The method of claim 21, comprising:

transmitting said first message to a base station; and

constructing a second message by said base station base don information received from said first message.

23. The method of claim 22, comprising:

scheduling said second message for transmission on downlink to said first set of mobile stations.
