Claim:
A method for creating a Content-on-Demand (CoD) service, the method comprising: receiving a Session Initiation Protocol (SIP) service request sent by a User Equipment (UE); converting the SIP service request into a Real-Time Streaming Protocol (RTSP) service request; sending the RTSP service request to a server; receiving an RTSP service response sent by the server, the RTSP service response being responsive to the RTSP service request; converting the RTSP service response into a SIP service response responsive to the SIP service request; sending the SIP service response to the UE to create the CoD service between the UE and the server, wherein the SIP service response carries RTSP content control channel parameter information and realtime transport protocol (RTP) content delivery channel parameter information; receiving an RTSP PLAY message sent by the UE, the RTSP PLAY message requesting playing of media streams; and forwarding the RTSP PLAY message to the server.
