Abstract

A system and methods for controlling identity privacy in a communication session include processing, at a communication server, a request from a first participant of the communication session to add a second participant to the communication session. Based on the request, the communication server establishes a set of privacy rules related to the second participant that control sharing of identity information between the second participant and a third participant of the communication session.

Claims

1. A method for controlling privacy in an on-going communication session, the method comprising:

at a communication server;

processing a request from a first participant of the on-going communication session to add a second participant to the on-going communication session, wherein the request further directs the communication server to establish a set of privacy rules related to the second participant; and

establishing the set of privacy rules related to the second participant, which controls sharing of identity information between the second participant and a third participant of the on-going communication session, wherein the establishing the set of privacy rules related to the second participant is performed based on the request from the first participant and wherein the established set of privacy rules override any privacy rules and privacy settings that are requested by the second participant when joining the on-going communication session.

2. The method of claim 1 further comprising:

providing an identity of the second participant to the third participant based on the set of established privacy rules.

3. The method of claim 1 further comprising:

providing the identity of the third participant to the second participant based on the set of established privacy rules.

4. The method of claim 1, wherein establishing the set of privacy rules comprises defining a non-permitted list that identifies at least one participant of the on-going communication session that is withheld from receiving an identity of the second participant.

5. The method of claim 1, wherein establishing the set of privacy rules comprises defining a non-permitted list that identifies at least one participant of the on-going communication session having an identity that is withheld from the second participant.

6. The method of claim 1, wherein establishing the set of privacy rules comprises defining a permitted list, which identifies at least one of:

at least one participant, but fewer than all participants, of the on-going communication session to receive an identity of the second participant; and

at least one participant, but fewer than all participants, of the on-going communication session having an identity that is provided to the second participant.

7. The method of claim 1, wherein establishing the set of privacy rules comprises selecting at least one of:

a participant privacy setting;

a plurality of participant privacy settings;

a privacy profile;

or a plurality of privacy profiles.

8. The method of claim 1, wherein establishing the set of privacy rules comprises assigning, to the second participant, a privacy setting related to the third participant.

9. The method of claim 1, wherein the on-going communication session includes at least one group, and wherein establishing the set of privacy rules comprises assigning, to the second participant, a privacy setting of the at least one group.

10. The method of claim 1, wherein the second participant has an attribute, and wherein establishing the set of privacy rules comprises assigning, to the second participant, a privacy setting based on the attribute.

11. A method for sharing participant identity information in an on-going communication session, the method comprising:

at a user equipment of a first participant of the on-going communication session;

inviting a second participant to the on-going communication session; and

directing a communication server to establish a set of privacy rules related to the second participant, which control sharing of identity information between the second participant and at least one other participant of the on-going communication session, and wherein the set of privacy rules override any privacy rules and privacy settings that are requested by the second participant when joining the on-going communication session.

12. The method of claim 11, wherein the set of privacy rules determine at least one of:

whether to provide identity information related to the second participant to the at least one other participant of the on-going communication session;

whether to provide identity information related to the at least one other participant to the second participant; and

wherein the at least one other participant comprises fewer than all participants of the on-going communication session.

13. The method of claim 11, wherein the set of privacy rules comprises selecting at least one of a participant privacy setting or a privacy profile.

14. The method of claim 11, wherein the set of privacy rules is established based on an attribute of the second participant.

15. The method of claim 11, wherein the set of privacy rules is established based on an attribute of the at least one other participant of the on-going communication session.

16. A system for controlling privacy in an on-going communication session, the system comprising:

a database that maintains identity information for a plurality of participants of the on-going communication session;

an interface that receives a request, from a first active participant of the plurality of participants, to include an additional participant in the on-going communication session, wherein the request further directs the interface to establish a set of privacy rules related to the additional participant; and

a processing device that, responsive to receiving the request, establishes the set of privacy rules related to the additional participant, which control sharing of identity information between the additional participant and a second active participant of the plurality of participants, and wherein the set of privacy rules override any privacy rules and privacy settings that are requested by the second participant when joining the on-going communication session.

17. The system of claim 16, wherein the system is a push to talk over cellular (PoC) server.

18. The system of claim 16, wherein the database further maintains a permitted list, which identifies at least one of:

at least one participant, but fewer than all participants, of the on-going communication session to receive an identity of the second participant; and

at least one participant, but fewer than all participants, of the on-going communication session having an identity that is provided to the second participant.
