A system and a method for monitoring a Video Phone (VP) service monitors a video communication between a calling video terminal and a called video terminal, and the system including a Mobile Switching Centre (MSC) server, a Media GateWay (MGW), a Video Inter-working Gateway (VIG), and a monitoring receiving unit. When the calling video terminal initiates a VP call to the called video terminal, the MSC server instructs the MGW to duplicate the call data of the calling and called video terminal, transmits the call data to the VIG, and instructs the VIG to de-multiplexes the call data of calling video terminal and called video terminal into the audio flow and video flow. The VIG transmits the audio flow and video flow to the monitoring receiving unit for playing. According to the above system and method, the embodiments of the present invention implement monitoring for VPs, which makes up the vacancy of video monitoring in the prior art and moreover implements more flexible monitoring without limitation of location and time. |
