Abstract

A method for providing interoperable communications with dynamic event area allocation includes facilitating communications of a plurality of virtual talk groups, each virtual talk group including a plurality of endpoints of different communication networks communicating using a respective communication protocol. The method includes receiving notice of an event comprising an event location and creating an event area based on the event location. The method also includes associating an event virtual talk group with the event for communications regarding the event. The method also includes modifying the event area based on at least one location parameter associated with the event.

Claims

1. A method for interoperable communications with a dynamic event area, comprising:

facilitating communications of a plurality of virtual talk groups, each virtual talk group comprising a plurality of endpoints of different communication networks communicating using a respective communication protocol;

receiving notice of an event comprising an event location;

creating an event area based on the event location;

associating an event virtual talk group with the event for communications regarding the event; and

modifying the event area based on at least one location parameter associated with the event.

2. The method of claim 1, wherein modifying the event area based on at least one location parameter associated with the event comprises uniformly expanding the event area outward, the location parameter comprising an estimated speed with which a subject of the event is moving.

3. The method of claim 1, wherein modifying the event area based on at least one location parameter associated with the event comprises expanding the event area outward in a non-uniform manner, the outward expansion comprising a rate of expansion in at least one direction based on an estimated speed with which a subject of the event is moving.

4. The method of claim 3, wherein the estimated speed with which the subject of the event is moving is based on a speed associated with at least one roadway within the event area.

5. The method of claim 1, further comprising creating an update channel for providing endpoints within the event virtual talk group with information relating to the event and a subject of the event.

6. The method of claim 1, further comprising:

receiving a notice updating a location of a subject of the event; and

modifying the event area based on the updated location of the subject of the event.

7. The method of claim 1, further comprising notifying endpoints within the event area that they are within the event area.

8. The method of claim 1, further comprising adding endpoints within the modified event area to the event virtual talk group.

9. The method of claim 1, further comprising removing endpoints from the event virtual talk group not within the modified event area.

10. The method of claim 1, further comprising adding endpoints of a first virtual talk group, of the plurality of virtual talk groups, to the event virtual talk group.

11. The method of claim 1, further comprising adding capacity to the event virtual talk group based on the modified event area.

12. A system for interoperable communications with a dynamic event area, comprising:

an interface operable to;

facilitate communications of a plurality of virtual talk groups, each virtual talk group comprising a plurality of endpoints of different communication networks communicating using a respective communication protocol; and

receive notice of an event comprising an event location; and

a processor coupled to the interface and operable to;

create an event area based on the event location;

associate an event virtual talk group with the event for communications regarding the event; and

modify the event area based on at least one location parameter associated with the event.

13. The system of claim 12, wherein the processor operable to modify the event area based on at least one location parameter associated with the event further comprises a processor operable to uniformly expanding the event area outward, the location parameter comprising an estimated speed with which a subject of the event is moving.

14. The system of claim 12, wherein the processor operable to modify the event area based on at least one location parameter associated with the event comprises a processor operable to expand the event area outward in a non-uniform manner, the outward expansion comprising a rate of expansion in at least one direction based on an estimated speed with which a subject of the event is moving.

15. The system of claim 14, wherein the estimated speed with which the subject of the event is moving is based on a speed associated with at least one roadway within the event area.

16. The system of claim 12, wherein the processor is further operable to create an update channel for providing endpoints within the event virtual talk group with information relating to the event and a subject of the event.

17. The system of claim 12, wherein:

the interface is further operable to receive a notice updating a location of a subject of the event; and

the processor is further operable to modify the event area based on the updated location of the subject of the event.

18. The system of claim 12, wherein the interface is further operable to notify endpoints within the event area that they are within the event area.

19. The system of claim 12, wherein the processor is further operable to add endpoints within the modified event area to the event virtual talk group.

20. The system of claim 12, wherein the processor is further operable to remove endpoints from the event virtual talk group not within the modified event area.

21. The system of claim 12, wherein the processor is further operable to add endpoints of a first virtual talk group, of the plurality of virtual talk groups, to the event virtual talk group.

22. The system of claim 12, wherein the processor is further operable to add capacity to the event virtual talk group based on the modified event area.

23. Logic embodied in a computer readable medium, the computer readable medium comprising code operable to:

facilitate communications of a plurality of virtual talk groups, each virtual talk group comprising a plurality of endpoints of different communication networks communicating using a respective communication protocol;

receive notice of an event comprising an event location;

create an event area based on the event location;

modify the event area based on at least one location parameter associated with the event.

24. The medium of claim 23, wherein the code operable to modify the event area based on at least one location parameter associated with the event comprises code operable to uniformly expand the event area outward, the location parameter comprising an estimated speed with which a subject of the event is moving.
