  • METHOD AND SYSTEM FOR TRANSFER OF CALL CONTROL
    Publication number: 20120124222
    Abstract: Means and methodology for a SIP Invite receiving node to withdraw from the SIP session set-up loop by replying a redirect message to the SIP Invite sending node. The redirect message contains information for setting up alternative SIP session, said information being available in the SIP Invite receiving node. This information is needed by the SIP invite sending node for establishing an alternative SIP session as well as information needed by other nodes and applications further on in the SIP session set-up loop. The SIP Invite sending node is specially adapted to retrieve the information from the redirect message for establishing a new SIP session based on and containing the information from the redirect message. Several implementations are given for use in an IP Multimedia Subsystem of a telecommunication network.
