METHOD AND SYSTEM FOR PROCESSING SIP MESSAGE WITH RTSP ENCAPSULATION IN IMS

摘要

The invention proposes a method and system for processing SIP message with RTSP encapsulation in IMS. The method comprises the following steps: defining a new SIP content type; and encapsulating a RTSP message into a SIP message with the new SIP content type. The invention realizes the use of the IMS security features, the reuse of the IMS QoS framework, the use of the existing IMS charging system, and the convergence of the RTSP-based services, such as IPTV and VoD, with the existing SIP-based IMS services.
