Patent ID: 7920578

Claim:
A system for monitoring a Video Phone (VP) service, applied for monitoring a video communication between a calling video terminal and a called video terminal, comprising a Mobile Switching Centre (MSC) server, a Media GateWay (MGW), a Video Inter-working Gateway (VIG), and a monitoring receiving unit; wherein the MSC server sends a call to the VIG upon the calling video terminal initiating a VP call to the called video terminal and instructs the MGW to duplicate call data of the calling video terminal and the called video terminal; the MGW duplicates the call data of the calling video terminal and the called video terminal, respectively, and transmits the call data to the VIG; the VIG receives the call sent by the MSC server, establishes a connection with the MGW, and receives the call data; the VIG de-multiplexes the call data into an audio flow and a video flow, and transmits the audio flow, the video flow, and a control signaling to the monitoring receiving unit; the monitoring receiving unit plays the audio flow and video flow according to the control signaling; wherein the monitoring receiving unit comprises a real time streaming protocol (RTSP) server, an RTSP website server, and an RTSP terminal; upon receiving the call sent by the MSC server, the VIG adds a number of the calling video terminal and a number of the called video terminal to a monitoring interface of the RTSP website server; the VIG converts the call data to an RTP flow, and transmits the RTP flow to the RTSP server; the RTSP server broadcasts the RTP flow to the RTSP website server through a network; the RTSP website server receives the RTP flow, and associates the RTP flow with the number of the calling video terminal and the number of the called video terminal displayed on the monitoring interface; and the RTSP terminal plays the RTP flow via accessing the monitoring interface of the RTSP website server.
