Abstract

A method and device for enabling selective privacy in a push to talk (PTT) wireless group communication session provides improved control over sharing of user identity information. The method includes processing at a PTT server a request for selective privacy. The PTT server then processes one or more selective privacy parameters, whereby at least a first session participant is enabled to receive an identification of a second session participant and a third session participant is not enabled to receive an identification of the second session participant. The PTT server then facilitates the PTT wireless group communication session between at least the first session participant, second session participant, and third session participant according to the one or more selective privacy parameters.

Claims

1. A method for enabling selective privacy in a push to talk (PTT) wireless group communication session, the method comprising:

processing at a PTT server a request for selective privacy;

processing at the PTT server one or more selective privacy parameters, whereby at least a first session participant is enabled to receive an identification of a second session participant and a third session participant is not enabled to receive an identification of the second session participant; and

facilitating at the PTT server the PTT wireless group communication session among at least the first session participant, second session participant, and third session participant according to the one or more selective privacy parameters.

2. The method of claim 1, wherein the one or more selective privacy parameters comprise an identification of the first session participant in a permitted list.

3. The method of claim 1, wherein the one or more selective privacy parameters comprise an identification of the third session participant in a not permitted list.

4. The method of claim 1, wherein the request for selective privacy is received from the second session participant.

5. The method of claim 1, wherein the one or more selective privacy parameters are automatically generated based on identity parameters associated with the first session participant, second session participant, or third session participant.

6. The method of claim 5, wherein the identity parameters include a domain name associated with the first, second, or third session participant.

7. The method of claim 1, wherein the one or more selective privacy parameters are included in a pre-defined selective privacy profile.

8. The method of claim 1, wherein the request for selective privacy is received from a PTT wireless group communication session originator or session target.

9. The method of claim 1, wherein the PTT server is a push to talk over cellular (PoC) server.

10. The method of claim 1, wherein the request for selective privacy is received from a session participant or is generated by the PTT server.

11. A push to talk (PTT) server, comprising:

a processor; and

a memory coupled to the processor, wherein the memory includes;

computer readable program code components for processing a request for selective privacy;

computer readable program code components for processing one or more selective privacy parameters, whereby at least a first session participant is enabled to receive an identification of a second session participant and a third session participant is not enabled to receive an identification of the second session participant; and

computer readable program code components for facilitating a PTT wireless group communication session between at least the first, second, and third session participants according to the one or more selective privacy parameters.

12. The server of claim 11, wherein the one or more selective privacy parameters comprise an identification of the first session participant in a permitted list.

13. The server of claim 11, wherein the one or more selective privacy parameters comprise an identification of the third session participant in a not permitted list.

14. The server of claim 11, wherein the request for selective privacy is received from the second session participant.

15. The server of claim 11, wherein the one or more selective privacy parameters are automatically generated based on identity parameters associated with the first session participant, second session participant, or third session participant.

16. The server of claim 15, wherein the identity parameters include a domain name associated with the first, second, or third session participant.

17. The server of claim 11, wherein the one or more selective privacy parameters are included in a pre-defined selective privacy profile.

18. The server of claim 11, wherein the request for selective privacy is received from a PTT wireless group communication session originator or session target.

19. The server of claim 11, wherein the server is a push to talk over cellular (PoC) server.

20. A push to talk (PTT) server, comprising:

means for processing a request for selective privacy;

means for processing one or more selective privacy parameters, whereby at least a first session participant is enabled to receive an identification of a second session participant and a third session participant is not enabled to receive an identification of the second session participant; and

means for facilitating a PTT wireless group communication session between at least the first, second, and third session participants according to the one or more selective privacy parameters.
