Abstract

A mobile communication device is provided that includes a wireless transceiver, a memory for storing contact information relating to other mobile communication devices of individuals and/or groups of individuals with whom the mobile communication device may communicate via the wireless transceiver; and a proximity-based configuration processor. The proximity-based configuration processor receives location information relating to locations of the other mobile communication devices, and configures the mobile communication device to communicate with the other mobile communication devices of the individuals and/or groups of individuals with a priority based on the location information.

Claims

1. A mobile communication device, comprising:

a wireless transceiver;

a memory for storing contact information relating to other mobile communication devices of individuals and/or groups of individuals with whom the mobile communication device may communicate via the wireless transceiver; and

a proximity-based configuration processor that receives location information relating to locations of the other mobile communication devices, and configures the mobile communication device to communicate with the other mobile communication devices of the individuals and/or groups of individuals with a priority based on the location information.

2. The mobile communication device of claim 1, wherein the proximity-based configuration processor is configured to receive the location information from the other mobile communication devices themselves.

3. The mobile communication device of claim 1, wherein the proximity-based configuration processor is configured to receive the location information from a system server responsible for providing such information.

4. The mobile communication device of claim 2, wherein the proximity-based configuration processor is configured to transmit location information requests to the other mobile communication devices to initiate receipt of the location information.

5. The mobile communication device of claim 4, wherein the location information requests include at least one waypoint with respect to which the location of the other mobile communications devices is requested.

6. The mobile communication device of claim 4, wherein the proximity-based configuration processor determines the location of the other mobile communication devices relative to a waypoint based on the received location information.

7. The mobile communication device of claim 3, wherein the proximity-based configuration processor is configured to transmit a request for the location information to the system server.

8. The mobile communication device of claim 7, wherein the location information requests include at least one waypoint with respect to which the location of the other mobile communications devices is requested.

9. The mobile communication device of claim 1, wherein the memory includes a group of individuals, and the proximity-based configuration processor effectuates the priority in a manner in which the group of individuals is displayed to a user in preparation for initiating a push-to-talk (PTT) communication.

10. The mobile communication device of claim 9, wherein a display of the group of individuals is prioritized in that group members having a nearer location relative to a waypoint are identified with higher priority than group members having a further location.

11. The mobile communication device of claim 9, wherein a display of the group of individuals is prioritized in that group members beyond a predetermined distance of a waypoint are not displayed within the group.

12. The mobile communication device of claim 9, wherein a display of the group of individuals is prioritized in that only the group member closest to a waypoint is displayed within the group.

13. A system comprising the mobile communication device of claim 1, and further comprising the other mobile communication devices, wherein each of the other mobile communication devices includes:

location determination circuitry for determining a location of the other mobile communication device; and

a wireless transceiver for communicating location information based on the determined location.

14. The system of claim 13, wherein each of the other mobile communication devices is configured to receive location information requests from another mobile device, and to respond by communicating the location information based on the determined location to the mobile device issuing the location information request.

15. The system of claim 14, wherein the location information communicated by each of the other mobile communication devices comprises the absolute location of the mobile communication device.

16. The system of claim 14, wherein the location information communicated by each of the other mobile communication devices comprises the location of the mobile communication device relative to a waypoint provided in the information requests.

17. The system of claim 13, wherein each of the other mobile communication devices is configured to receive location information requests from a system server, and to respond by communicating the location information based on the determined location to the system server.

18. The system of claim 17, further comprising the system server.

19. A method of conducting PTT communications among mobile communication devices, comprising the steps of:

presenting a group of individuals with whom the mobile communication devices may communicate via a PTT communication; and

prioritizing the group of individuals for purposes of the PTT communication based on location information relating to the locations of the individuals.

20. The method of claim 19, wherein the location information relates to the locations of the individuals relative to a predefined waypoint.

21. The method of claim 20, wherein the group of individuals are prioritized by displaying the group members on a mobile communication device initiating the PTT communication in an order based on proximity to the waypoint.

22. The method of claim 20, wherein the group of individuals are prioritized by displaying a reduced number of group members based on their proximity to the waypoint.

23. The method of claim 20, wherein the predefined waypoint is acquired from a database shared among the group of individuals.
