Abstract

In an embodiment of a method of the present invention, the method includes the acts of establishing a dispatch multi-party call between a set of communication devices and establishing a sidebar communication between a subset of the set of communication devices. The set of communication devices participate in the dispatch multi-party call and only the subset of communication devices participate in the sidebar communication. In an embodiment of a system of the present invention, the system includes a dispatch network and a set of communication devices in communication with the dispatch network. The dispatch network establishes a dispatch multi-party call between the set of communication devices and a sidebar communication between a subset of the set of communication devices, wherein the set of communication devices participate in the dispatch multi-party call and only the subset of communication devices participate in the sidebar communication.

Claims

1. A method for conducting a dispatch multi-party call, the method comprising the acts of:

establishing a dispatch multi-party call between a set of communication devices; and

establishing a sidebar communication between a subset of the set of communication devices;

wherein the set of communication devices participate in the dispatch multi-party call and wherein only the subset of communication devices participate in the sidebar communication.

2. The method of claim 1 wherein the dispatch multi-party call is a group call.

3. The method of claim 2 wherein the set of communication devices is defined by a participant in the group call prior to establishing the group call.

4. The method of claim 2 wherein the set of communication devices is selectively dynamically defined by a participant in the group call in conjunction with establishing the group call.

5. The method of claim 1 wherein the dispatch multi-party call is a chatroom.

6. The method of claim 1 further comprising the act of mixing the dispatch multi-party call and the sidebar communication to produce a single audio output.

7. The method of claim 6 wherein the act of mixing is performed in a dispatch network.

8. The method of claim 6 wherein the act of mixing is performed in the subset of communication devices.

9. The method of claim 6 wherein the act of mixing is performed in a dispatch network for a first communication device of the subset of communication devices and wherein the single audio output is provided to the first communication device from the dispatch network and further wherein the act of mixing is performed for a second communication device of the subset of communication devices in the second communication device.

10. The method of claim 6 wherein the act of mixing includes the act of attenuating the dispatch multi-party call.

11. The method of claim 6 wherein the act of mixing includes the act of muting the dispatch multi-party call.

12. The method of claim 1 wherein the sidebar communication is a dispatch call.

13. The method of claim 1 wherein the sidebar communication is an interconnect call.

14. The method of claim 1 wherein the sidebar communication is a text message session.

15. The method of claim 1 further comprising the acts of:

maintaining a profile of a participant in the sidebar communication in a dispatch network; and

determining by the dispatch network a method for conducting the sidebar communication with the participant based on the profile.

16. The method of claim 1 further comprising the act of notifying a communication device of the subset of communication devices of the establishment of the sidebar communication.

17. The method of claim 16 wherein the act of notifying includes providing an audible tone.

18. The method of claim 16 wherein the act of notifying includes providing a visible signal.

19. The method of claim 1 further comprising the act of inviting a communication device of the subset of communication devices to participate in the sidebar communication.

20. A system for conducting a dispatch multi-party call, comprising:

a dispatch network; and

a set of communication devices in communication with the dispatch network;

wherein the dispatch network establishes a dispatch multi-party call between the set of communication devices and a sidebar communication between a subset of the set of communication devices;

and wherein the set of communication devices participate in the dispatch multi-party call and wherein only the subset of communication devices participate in the sidebar communication.

21. The system of claim 20 wherein the dispatch multi-party call is a group call.

22. The system of claim 20 wherein an identification of the set of communication devices is stored in the dispatch network.

23. The system of claim 20 wherein the dispatch multi-party call is a chatroom.

24. The system of claim 20 wherein the dispatch network mixes the dispatch multi-party call and the sidebar communication to produce a single audio output.

25. The system of claim 20 wherein the subset of communication devices mixes the dispatch multi-party call and the sidebar communication to produce a single audio output.

26. The system of claim 20 wherein the dispatch network mixes the dispatch multi-party call and the sidebar communication to produce a first single audio output for a first communication device of the subset of communication devices and wherein the first single audio output is provided to the first communication device from the dispatch network and further wherein a second communication device of the subset of communication devices mixes the dispatch multi-party call and the sidebar communication to produce a second single audio output for the second communication device.

27. The system of claim 20 wherein the sidebar communication is a dispatch call.

28. The system of claim 20 wherein the sidebar communication is an interconnect call.

29. The system of claim 20 wherein the sidebar communication is a text message session.

30. The system of claim 20 wherein the dispatch network maintains a profile of a participant in the sidebar communication and wherein the dispatch network determines a method for conducting the sidebar communication with the participant based on the profile.

31. A method for conducting a dispatch multi-party call, the method comprising the acts of:

establishing a dispatch multi-party call between a set of communication devices; and

establishing a sidebar communication between at least one communication device of the set of communication devices and a communication device that is not included in the set of communication devices;

wherein the set of communication devices participate in the dispatch multi-party call and wherein only the at least one communication device of the set of communication devices and the communication device that is not included in the set of communication devices participate in the sidebar communication.
