Abstract

An embodiment of the current invention is directed to a method of reducing the latency associated with communicating data to a mobile device. It is determined that a threshold period of time has elapsed since a mobile device has communicated a location-determining message. A request for the mobile device to transition to a quick-paging recognition mode is sent to a mobile device configured to perform a process. The process includes: sending a response to the first request as a location-determining message; transitioning to a quick-page recognition mode; receiving an indication to receive a paging-channel message; acquiring the paging-channel message; and returning to the quick-page recognition mode.

Claims (41)

1. One or more nontransitory computer-readable media having computer-executable instructions embodied thereon that when executed by a computing device cause the computing device to perform a method of reducing a latency associated with communicating data to a mobile device, the method comprising:

determining that a threshold period of time has elapsed since the mobile device has communicated a location-determining message to the computing device, wherein said location-determining message enables said computing device to identify an appropriate basestation that should be used to send data to the mobile device;

sending from the computing device a first request to the mobile device for the mobile device to transition to a quick-paging recognition mode, wherein said mobile device is configured to perform a process incident to receiving said first request, wherein said process includes,

(A) sending a response, responding to the first request to transition to a quick-paging recognition mode, said response being a location-determining message,

(B) transitioning to the quick-paging recognition mode,

(C) receiving an indication to receive a paging-channel message from the computing device,

(D) acquiring the paging-channel message by listening to a paging channel, and

(E) returning to the quick-paging recognition mode.

2. The media of claim 1 , wherein the process further includes:

receiving a second request, indicating a transition out of the quick-paging recognition mode; and

transitioning out of the quick-paging recognition mode.

3. The media of claim 2 , wherein transitioning out of the quick-paging recognition mode comprises listening to the paging channel at each of one or more associated time slots.

4. The media of claim 1 , wherein the first request comprises a two-bit message.

5. The media of claim 4 , wherein the first request comprises two bits of information and two bits of redundancy.

6. The media of claim 1 , wherein transitioning to a quick-paging recognition mode comprises not listening to a paging channel.

7. The media of claim 1 , wherein the response comprises a repeat of the first indication.

8. The media of claim 1 , wherein the response is sent utilizing a slotted protocol.

9. The media of claim 1 , wherein acquiring the paging-channel message comprises listening to the paging channel during a next associated time slot.

10. One or more nontransitory computer-readable media having computer-executable instructions embodied thereon that when executed by a computing device cause the computing device to perform a method of reducing a latency associated with communicating data to a mobile device, the method comprising:

sending from the computing device a first request to the mobile device for the mobile device to transition to a tracking mode, wherein said first request is responsive to a threshold period of time elapsing since the mobile computing device has communicated a location-determining message to the computing device, wherein said mobile device is configured to perform a process incident to receiving said first request, wherein said process includes,

(A) transitioning to the tracking mode, and

(B) transmitting a location-update message in response to a change in location of the mobile computing device.

11. The media of claim 10 , the process further including:

receiving a second request, indicating a transition out of the tracking mode; and

transitioning out of the tracking mode.

12. The media of claim 11 , wherein the first request is sent utilizing a slotted protocol.

13. The media of claim 11 , wherein transmitting a location-update message comprises sending a message on a data channel to a base station currently utilized for communication.

14. The media of claim 11 , wherein a change in location comprises utilizing a new base station for communication.

15. The media of claim 10 , wherein the first request comprises a two-bit message.

16. The media of claim 15 , wherein the first request comprises two bits of information and two bits of redundancy.

17. One or more nontransitory computer-readable media having computer-executable instructions embodied thereon that when executed by a mobile device cause the mobile device to perform a method of reducing a latency associated with a communication network communicating data to the mobile device, the method comprising:

receiving at the mobile device a first four-bit request, indicating the mobile device to transition to a quick-paging recognition mode, said first four-bit request being sent utilizing a slotted protocol;

transitioning to the quick-paging recognition mode;

receiving a second four-bit request, indicating a paging-channel message will be sent to the mobile device, said second four-bit request being sent utilizing a slotted protocol;

acquiring the paging-channel message by listening to a paging channel; and

returning to the quick-paging recognition mode.

18. The media of claim 17 , further comprising:

receiving a third four-bit request, indication a transition out of the quick-paging mode, said third four-bit request being sent utilizing a slotted protocol; and

transitioning out of the quick-paging, recognition mode.

19. The media of claim 17 , wherein the first request comprises two bits of information and two bits of redundancy.

20. The media of claim 17 , wherein acquiring the paging-channel message comprises listening to the paging channel during a next associated time slot.
