发明名称 Method and Arrangement for Making a Call-Setup
摘要 A method and arrangement for providing a ring-back presentation to a calling terminal after receiving a call setup request from the calling terminal for a first communication session with a called terminal. A second packet-based communication session is established with the calling terminal, independent of the first session, and pre-defined media content is provided as said ring-back presentation to the calling terminal over the second session. Thereby, ring-back presentations to waiting callers can be selected from a great range of media types, including visual media. A calling user can also control the playout or display of the ring-back presentation irrespective of when the call is answered.
