Abstract

The present invention discloses a system for legitimately monitoring the audio and video multimedia conference, including: a monitoring control terminal, a monitoring answer terminal, an application server and a media server, wherein, the application server is used to realize the processing logic of audio and video multimedia conference service and the legitimate monitoring; the medium service apparatus can be used to realize the media processing of the audio and video multimedia conference and the legitimate monitoring; and the monitoring control terminal can be used to initiate monitor indication and perform monitor management. The present invention also discloses a method for legitimately monitoring the audio and video multimedia conference, which realizes legitimate monitoring function by using the apparatus and function in the audio and video multimedia conference service. The present invention is suitable for audio and video multimedia conference in the field of NGN or IMS communications.

Description

technical field [0001] The present invention relates to technologies related to audio and video multimedia conferences in the communication field of NGN (Next Generation Network, next generation communication network) or IMS (IP Multimedia Subsystem, IP Multimedia Subsystem), in particular to related technologies of legal interception in audio and video multimedia conferences. Background technique [0002] With the continuous expansion of the application fields of NGN and IMS communication networks, there are more and more related intelligent services based on NGN and IMS. Among them, the audio-video multimedia conference service is a typical service, which is initiated by users through customized terminals or IE clients. Multimedia conference, call multiple conference members, conference members talk to each other with video, etc. At the same time, the user controls the conference on the customized terminal or IE client. [0003] Due to national laws and regulations and oth...
