Abstract

A method is provided of distributing push-to-talk group identifiers. When the PTT group is created, the user terminal for the group creator automatically generates and sends a group identification message containing the group identifier to the other group members. The user terminals receiving the message recognize that it contains a PTT group identifier and execute and group list update process to add the new group to a locally stored group list or contact list.

Claims

1. A method implemented by a Push-to-Talk (PTT) terminal of distributing a group identification for a PTT group comprising:

receiving a group identifier from a group server following registration of a PTT group;

generating a group identification message including said group identifier responsive to receipt of the group identifier from the group server; and

sending the group identification message to one or more group members.

2. The method of claim 1 wherein generating a group identification message comprises prompting the user responsive to receipt of the group identifier from the group server, receiving user input receive user input responsive to the user prompt, and generating a group identification message if the user input indicates approval to send a group identification message.

3. The method of claim 1 further comprising updating a group list stored in the PTT terminal responsive receipt of the group identifier from the group server.

4. The method of claim 3 wherein updating the group list comprises adding a new group to the group list and associating the group identifier with the new group.

5. The method of claim 1 wherein the group identification message comprises one of a text message, an instant message, email application and a multimedia message.

6. The method of claim 5 wherein the group identification message includes an active component that can be triggered by the recipient to automatically update the recipient'"'"'s group list with a new group associated with the group identifier.

7. A method implemented by a Push-to-Talk (PTT) terminal of updating a group list for storing persistent PTT groups, comprising:

receiving a group identification message including a group identifier; and

updating a group list stored in the PTT terminal responsive to receipt of the group identification message to include a new group and associating the group identifier with the new group.

8. The method of claim 7 wherein updating a group list comprises prompting the user responsive to receipt of the group identification message, receiving user input responsive to the prompt, and updating the group list if the user input indicates approval.

9. The method of claim 7 wherein the group identification message is received by a messaging application on the PTT terminal.

10. The method of claim 9 wherein updating the group list comprises detecting the group identifier in the group identification message by the messaging application, sending the group identifier from the messaging application to a PTT application, and updating the group list by the PTT application.

11. The method of claim 10 wherein the messaging application comprises one of a text messaging application, instant messaging application, email application and multimedia messaging application.

12. The method of claim 7 wherein the group identification message includes an active component that when selected by the recipient causes a new group to be added to the user'"'"'s group list.

13. A user terminal comprising:

memory to store a group list for PTT groups;

a processing circuit configured to;

register a PTT group with a group server;

receive a group identifier from the group server responsive to registration of the PTT group;

generate a group identification message including said group identifier following receipt of the group identifier from the group server; and

send the group identification message to one or more group members.

14. The user terminal of claim 13 wherein the processor generates a group identification message by prompting the user responsive to receipt of the group identifier from the group server, receiving user input responsive to the user prompt, and generating a group identification message if the user input indicates approval to generate a group identification message.

15. The user terminal of claim 13 further comprising updating a group list stored in the PTT terminal responsive receipt of the group identifier from the group server.

17. The user terminal of claim 13 wherein the group identification message comprises one of a text message, an instant message, email application and a multimedia message.

18. The user terminal of claim 17 wherein the group identification message includes an active component that can be triggered by the recipient to automatically update the recipient'"'"'s group list with a new group associated with the group identifier.

16. The user terminal of claim 16 wherein the processing circuit updates the group list by adding a new group to the group list and associating the group identifier with the new group.

19. A user terminal comprising:

memory to store a group list for PTT groups;

a processing circuit configured to;

receive a group identification message including a group identifier; and

update a group list stored in the PTT terminal responsive to receipt of the group identification message to include a new group and associating the group identifier with the new group.

20. The user terminal of claim 19 wherein the processing circuit updates the group list by prompting the user responsive to receipt of the group identification message, receiving user input responsive to the user prompt, and updating the group list if the user input indicates approval to update the group list.

21. The user terminal of claim 19 wherein the group identification message is received by a messaging application on the PTT terminal.

22. The user terminal of claim 21 wherein updating the group list comprises detecting the group identifier in the group identification message by a messaging application, passing the group identifier from the messaging application to a second application, and updating the group list by the second application.

23. The user terminal of claim 22 wherein the second application is a PTT application.

24. The user terminal of claim 22 wherein the messaging application comprises one of a text messaging application, instant messaging application, email application and multimedia messaging application.

25. The user terminal of claim 19 wherein the group identification message includes an active component that when selected by the recipient causes a new group to be added to the user'"'"'s group list.

26. A computer readable media containing a computer program, said computer program comprising code to:

register a PTT group with a group server;

receive a group identifier from the group server responsive to registration of the PTT group;

generate a group identification message including said group identifier following receipt of the group identifier from the group server; and
