Abstract

A wireless communication system and method poll subscribers based on a movement history for the subscribers. Movement information for subscribers is stored and analyzed to determine the likely current location(s) for a subscriber. Polling is performed based on a result of analyzing the movement information. For example, polling the subscriber can be performed using transmitters in a serial manner, such that a first transmitter, or group of transmitters, that corresponds to the most likely current location of the subscriber is used to poll the subscriber. If polling using the first transmitter is not successful, a second transmitter, or group of transmitters, corresponding to a second most likely location of the subscriber is used to poll the subscriber, and so on.

Claims

1. A method for polling a subscriber in a wireless communication system, comprising:

storing movement information related to a subscriber;

analyzing the movement information for the subscriber; and

polling the subscriber based on a result of analyzing the movement information for the subscriber.

2. The method of claim 1, wherein the step of storing movement information comprises storing past location information for the subscriber.

3. The method of claim 1, wherein the step of storing movement information comprises storing information in addition to location information.

4. The method of claim 1, wherein the step of analyzing the movement information comprises determining the likelihood that the subscriber is currently located at at least one location based on the movement information for the subscriber.

5. The method of claim 1, wherein the step of analyzing the movement information comprises determining the probability that a subscriber is currently at each of a plurality of locations based on the movement information for the subscriber.

6. The method of claim 5, wherein the movement information includes location and time information.

7. The method of claim 1, wherein the step of analyzing the movement information comprises selecting portions of the movement information for analysis.

8. The method of claim 1, wherein the step of polling the subscriber comprises using transmitters in the communications system in a serial manner.

9. The method of claim 1, wherein the step of polling the subscriber comprises using a first at least one transmitter that corresponds to a first most likely location for the subscriber to poll the subscriber, and if a polling operation for the first at least one transmitter is unsuccessful, using a second at least one transmitter that corresponds to a second most likely location for the subscriber to poll the subscriber.

10. The method of claim 1, wherein the step of polling the subscriber comprises controlling a frequency of polling the subscriber based on the result of analysis.

11. A method for polling a subscriber in a wireless communication system, comprising:

storing location information related to past detected locations of a subscriber;

determining a set of probable current locations for a subscriber based on the location information; and

polling the subscriber using transmitters in the communication system in a serial manner, such that a first at least one transmitter corresponding to a first most likely location for the subscriber is first used to poll the subscriber, and if a polling operation of the first at least one transmitter is unsuccessful, a second at least one transmitter corresponding a second most likely location for the subscriber is next used to poll the subscriber.

13. The wireless communication system of claim 12, further comprising:

a plurality of transmitters that can communicate with the subscriber, each transmitter having a corresponding coverage area.

14. The wireless communication system of claim 13, wherein the coverage areas for at least two transmitters overlap at least partially.

15. The wireless communication system of claim 13, wherein the polling controller uses the plurality of transmitters in a serial manner based on the result of analysis of the movement information for the subscriber.

16. The wireless communication system of claim 13, wherein the history analyzer determines a set of most likely current subscriber locations;

and

the polling controller uses the transmitters in a serial manner to poll the subscriber, such that a first at least one transmitter corresponding to a most likely current subscriber location is used to poll the subscriber, and if a polling operation for the first at least one transmitter is not successful, a second at least one transmitter corresponding to a second most likely current subscriber location is used to poll the subscriber.

17. The wireless communication system of claim 12, further comprising:

an interface that allows a user to input information into and receive information from the communications system.

18. The wireless communication system of claim 12, further comprising:

a communications network that provides information for and receives information from subscribers of the communication system.

19. The wireless communication system of claim 12, wherein the memory stores movement information for a plurality of subscribers.

20. The wireless communication system of claim 12, wherein the polling controller controls a frequency of polling for the subscriber based on the result of analysis.

12. A wireless communication system comprising:

a memory that stores movement information related to at least one subscriber;

a history analyzer that analyzes the movement information for a subscriber; and

a polling controller that polls the subscriber based on a result of analyzing the movement information for the subscriber.
