  • Method and apparatus for providing customized ringback to calling party devices in an IMS network
    Publication number: 20070121595
    Abstract: An exemplary method provides ringback information to a calling party device. A call establishment request is received in an Internet Protocol (IP) Multimedia Subsystem (IMS) network from the calling party device by a session initiation protocol, SIP, application server, SIP-AS. Ringback information associated with the called party, which may require condition evaluation such as time-of-day, day-of-week or may be unconditionally determined, is identified in response to the call establishment request. A push transmission technique is used by the SIP-AS to transmit the ringback information via one or more bearer packets sent from the SIP-AS to the calling party device.
