Abstract

A method for managing a plurality of virtual talk groups includes forming a first virtual talk group associated with a first endpoint. The first virtual talk group includes the first endpoint and a second endpoint. The second endpoint is associated with a first function. The method also includes facilitating communications between the endpoints of the first virtual talk group. The method also includes, upon a change in a function of the first endpoint from the first function to a second function, receiving a request to add a third endpoint to the first virtual talk group. The third endpoint is associated with the second function. The method also includes adding the third endpoint to the first virtual talk group and removing the second endpoint from the first virtual talk group after the third endpoint has been added to the first virtual talk group for a first amount of time.

Claims

1. A method for managing a plurality of virtual talk groups, comprising:

forming a first virtual talk group associated with a first endpoint, the first virtual talk group comprising the first endpoint and a second endpoint, the second endpoint associated with a first function;

facilitating communications between the endpoints of the first virtual talk group;

upon a change in a function of the first endpoint from the first function to a second function, receiving a request to add a third endpoint to the first virtual talk group, the third endpoint associated with the second function;

adding the third endpoint to the first virtual talk group; and

removing the second endpoint from the first virtual talk group after the third endpoint has been added to the first virtual talk group for a first amount of time.

2. The method of claim 1, wherein facilitating communications between the endpoints of the first virtual talk group comprises facilitating communications of the first virtual talk group to the first endpoint through a first communication channel associated with the first endpoint.

3. The method of claim 1, wherein the request to add the third endpoint to the first virtual talk group is received from the second endpoint.

4. The method of claim 1, wherein removing the second endpoint from the first virtual talk group after the third endpoint has been added to the first virtual talk group for a first amount of time comprises receiving from the third endpoint a request to remove the second endpoint from the first virtual talk group.

5. The method of claim 1, wherein the first endpoint comprises a pilot of an airplane, the second endpoint comprises an airport dispatcher and the third endpoint comprises an air traffic controller.

6. The method of claim 1, wherein receiving a request to add a third endpoint to the first virtual talk group comprises receiving a change in a location parameter of the first endpoint, the change in the location parameter of the first endpoint corresponding to the change in the function of the first endpoint.

7. The method of claim 1, further comprising alerting the first endpoint that the third endpoint will be added to the first virtual talk group and that the second endpoint will be removed from the first virtual talk group.

8. A system for managing a plurality of virtual talk groups, comprising:

a processor operable to;

form a first virtual talk group associated with a first endpoint, the first virtual talk group comprising the first endpoint and a second endpoint, the second endpoint associated with a first function; and

facilitate communications between the endpoints of the first virtual talk group; and

an interface coupled to the processor and operable to;

upon a change in a function of the first endpoint from the first function to a second function, receive a request to add a third endpoint to the first virtual talk group, the third endpoint associated with the second function;

wherein the processor is further operable to;

add the third endpoint to the first virtual talk group; and

remove the second endpoint from the first virtual talk group after the third endpoint has been added to the first virtual talk group for a first amount of time.

9. The system of claim 8, wherein the processor operable to facilitate communications between the endpoints of the first virtual talk group comprises a processor operable to facilitate communications of the first virtual talk group to the first endpoint through a first communication channel associated with the first endpoint.

10. The system of claim 8, wherein the request to add the third endpoint to the first virtual talk group is received from the second endpoint.

11. The system of claim 8, wherein the processor operable to remove the second endpoint from the first virtual talk group after the third endpoint has been added to the first virtual talk group for a first amount of time comprises a processor operable to remove the second endpoint from the first virtual talk group after the receipt by the interface of a request from the third endpoint to remove the second endpoint from the first virtual talk group.

12. The system of claim 8, wherein the first endpoint comprises a pilot of an airplane, the second endpoint comprises an airport dispatcher and the third endpoint comprises an air traffic controller.

13. The system of claim 8, wherein the interface operable to receive a request to add a third endpoint to the first virtual talk group comprises an interface operable to receive a change in a location parameter of the first endpoint, the change in the location parameter of the first endpoint corresponding to the change in the function of the first endpoint.

14. The system of claim 8, wherein the processor is further operable to alert the first endpoint that the third endpoint will be added to the first virtual talk group and that the second endpoint will be removed from the first virtual talk group.

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

form a first virtual talk group associated with a first endpoint, the first virtual talk group comprising the first endpoint and a second endpoint, the second endpoint associated with a first function;

facilitate communications between the endpoints of the first virtual talk group;

upon a change in a function of the first endpoint from the first function to a second function, receive a request to add a third endpoint to the first virtual talk group, the third endpoint associated with the second function;

add the third endpoint to the first virtual talk group; and

remove the second endpoint from the first virtual talk group after the third endpoint has been added to the first virtual talk group for a first amount of time.

16. The medium of claim 15, wherein the code operable to facilitate communications between the endpoints of the first virtual talk group comprises code operable to facilitate communications of the first virtual talk group to the first endpoint through a first communication channel associated with the first endpoint.

17. The medium of claim 15, wherein the request to add the third endpoint to the first virtual talk group is received from the second endpoint.

18. The medium of claim 15, wherein the code operable to remove the second endpoint from the first virtual talk group after the third endpoint has been added to the first virtual talk group for a first amount of time comprises code operable to receive from the third endpoint a request to remove the second endpoint from the first virtual talk group.

19. The medium of claim 15, wherein the first endpoint comprises a pilot of an airplane, the second endpoint comprises an airport dispatcher and the third endpoint comprises an air traffic controller.

20. The medium of claim 15, wherein the code operable to receive a request to add a third endpoint to the first virtual talk group comprises code operable to receive a change in a location parameter of the first endpoint, the change in the location parameter of the first endpoint corresponding to the change in the function of the first endpoint.

21. The medium of claim 15, wherein the code is further operable to alert the first endpoint that the third endpoint will be added to the first virtual talk group and that the second endpoint will be removed from the first virtual talk group.

22. A system for managing a plurality of virtual talk groups, comprising:

means for forming a first virtual talk group associated with a first endpoint, the first virtual talk group comprising the first endpoint and a second endpoint, the second endpoint associated with a first function;

means for facilitating communications between the endpoints of the first virtual talk group;
