Abstract

By signalling information for establishing the push-to-talk communication of a first terminal with a switching node in a mobile telecommunications network, establishing a usable link with the switching node from the first terminal and then establishing a usable link with at least one other terminal from the switching node, a push-to-talk connection is established.

Claims

1-17. -17. (canceled)

18. A method for providing a push-to-talk connection between at least two user terminals in a communications network, comprising

signaling information from a first terminal to set up a push-to-talk connection to a switching node;

establishing a usable link from the first terminal to the switching node; and

establishing a usable link from the switching node to at least one further terminal.

19. A method as claimed in claim 18, wherein useable links established are speech connections.

20. A method as claimed in claim 19, wherein the communications network is a mobile communications network.

21. A method as claimed in claim 20, wherein at least one terminal is represented by a mobile terminal.

22. A method as claimed claim 21, wherein the information is signaled by means of USSD.

23. A method as claimed in claim 22, wherein the usable link from the first terminal to the switching node is established before setting up the push-to-talk connection to the switching node.

24. A method as claimed in claim 23, wherein the information is signaled by UUS.

25. A method as claimed in claim 24, further comprising initiating ending of the useable link by one of the first terminal and the at least one other terminal.

26. A method as claimed in claim 25, further comprising acknowledging receipt of the signaled information by the switching node.

27. A method as claimed in claim 26, further comprising loading application software onto the first terminal prior to initiating the push-to-talk connection.

28. A terminal for push-to-talk communication with at least one other user terminal in a communications network having a switching node, comprising:

means for signaling information to the switching node to set up a push-to-talk connection to the switching node;

means for establishing a usable link to the switching node; and

means for requesting a usable link from the switching node to at the least one other terminal.

29. A terminal as claimed in claim 28, wherein said means for signaling information uses USSD or UUS.

30. A terminal as claimed in claim 29, further comprising means for loading application software for initiating a push-to-talk connection.

31. A switching node in a communications network for push-to-talk communication between at least two user terminals, comprising:

means for receiving signaling information from a first terminal to set up a push-to-talk connection; and

means for establishing usable links to the first terminal and at least one other terminal.

32. A switching node as claimed in claim 31, further comprising means for acknowledging the signaling information.

33. A switching node as claimed in claim 32, further comprising means for controlling the push-to-talk connection.

34. A switching node as claimed in claim 33, wherein said means for controlling uses USSD or UUS.
