Abstract

A method and apparatus for reducing power consumption in a wireless communication system is described. The monitoring of an access network is ceased by issuing a ControlChannelMAC.Deactivate command, a SharedSignallingMAC.Deactivate command and a ForwardTrafficChannelMAC.Deactivate command. Processing of resources is shut down to reduce power consumption.

Claims

1. A method of reducing power consumption in a wireless communication system, characterized in that:

ceasing to monitor an access network by issuing a ControlChannelMAC.Deactivate command, a SharedSignallingMAC.Deactivate command and a ForwardTrafficChannelMAC.Deactivate command; and

shutting down processing resources to reduce power consumption.

2. The method as claimed in claim 1, characterized in that determining if a queued OpenConnection command is present.

3. The method as claimed in claim 1, characterized in that transitioning to an Access State.

4. The method as claimed in claim 1, characterized in that transitioning to a monitor state to update overhead messages

5. The method as claimed in claim 4, characterized in that determining the time of transition to the monitor state by relying on an ExtendedChannelInfoExpiryTime.

6. The method as claimed in claim 1, characterized in that transitioning to the monitor state in superframes specified by a PageTimes array to receive pages.

7. The method as claimed in claim 6, characterized in that the transitioning comprises specifying supreframes as a function of the PageTimes array.

8. The method as claimed in claim 1, characterized in that transitioning to the monitor state in superframe T+FastRepageInterval to receive fast repages.

9. The method as claimed in claim 8, characterized in that the transitioning comprises:

determining if there was any paging error on last page read by an access terminal; and

determining if the superframe is an entry in the PageTimes array.

10. A computer readable medium including instructions stored thereon, characterized in that:

a first set of instructions for ceasing to monitor an access network by issuing a ControlChannelMAC.Deactivate command, a SharedSignallingMAC.Deactivate command and a ForwardTrafficChannelMAC.Deactivate command; and

a second set of instructions for shutting down processing resources to reduce power consumption.

11. An apparatus operable in a wireless communication system, characterized in that:

means for ceasing to monitor an access network by issuing a ControlChannelMAC.Deactivate command, a SharedSignallingMAC.Deactivate command and a ForwardTrafficChannelMAC.Deactivate command; and

means for shutting down processing resources to reduce power consumption.

12. The apparatus as claimed in claim 11, characterized in that means for determining if a queued OpenConnection command is present.

13. The apparatus as claimed in claim 11, characterized in that means for transitioning to an Access State.

14. The apparatus as claimed in claim 11, characterized in that means for transitioning to a monitor state to update overhead messages

15. The apparatus as claimed in claim 14, characterized in that means for determining the time of transition to the monitor state by relying on an ExtendedChannelInfoExpiryTime.

16. The apparatus as claimed in claim 11, characterized in that means for transitioning to the monitor state in superframes specified by a PageTimes array to receive pages.

17. The apparatus as claimed in claim 16, characterized in that means for transitioning comprises specifying superframes as a function of the PageTimes array.

18. The apparatus as claimed in claim 11, characterized in that means for transitioning to the monitor state in superframe T+FastRepageInterval to receive fast repages.

19. The apparatus as claimed in claim 18, characterized in that means for transitioning comprises:

means for determining if there was any paging error on last page read by an access terminal; and

means for determining if the superframe is an entry in the PageTimes array.
