摘要

A user equipment (UE), comprising at least one component configured to support controlling a media stream and modifying Internet Protocol-Connectivity Access Network (IP-CAN)/Radio Access Network (RAN) and Internet Packet (IP) Multimedia Subsystem (IMS) media resources, wherein the IP-CAN/RAN and IMS media resources are modified using a Session Initiation Protocol (SIP) RE-INVITE request to an IMS network, and wherein the media stream is controlled using a Real Time Streaming Protocol (RTSP) request to a media server. Also included is a UE comprising at least one component configured to support a method comprising sending a RTSP request to a signaling/control server in communications with a media server to control a media stream, wherein a SIP RE-INVITE request associated with the RTSP request is further sent from the UE or the signaling/control server to an IMS network to modify media resources associated with the media stream.
