Embodiment
Hereinafter with reference to accompanying drawing embodiments of the invention are described, it should be noted that the preferred embodiment that provides following with provide to of the present invention comprehensively and thorough, rather than the present invention carried out any restriction.
Preferred embodiment as shown in Figure 1 is the system configuration schematic diagram that is used for the audio/video multimedia conference Lawful Interception.As shown in Figure 1, this system except comprise one monitor control end 101, terminal 102, application server (Application Server are answered in a monitoring, AS) 103, be the server that is deployed on IMS or the NGN core net, be used to the processing logic of realizing that audio/video multimedia conference and meeting are monitored; Also comprise: media server (Media Server, MS) 104, be the media device of realizing audio/video multimedia conference and monitoring.
In said system, monitor control end 101 and can be custom terminal or generic browser, implementation on multimedia conferencing is decided, and can carry out communication by standard agreement (can use but be not limited to SIP, HTTP etc.) with application server 103, so that initiate the Lawful Interception indication; Monitoring is answered terminal 102 and is common communicating terminal, for example: and plain old telephone, GSM, CDMA isotype mobile phone, Personal Handyphone System, video telephone etc., and be connected to application server 103 by core net.When application server 103 is answered terminal 102 adding meetings with monitoring, the setting monitoring is answered terminal 102 and is received only medium, do not send medium, answer the audio/video multimedia conference that terminal 102 influences normal users to avoid monitoring, simultaneously, the process that terminal 102 adds meeting is answered in monitoring, all is transparent to other member in the meeting, i.e. the normal member of meeting can not perceive meeting and be monitored.104 of media servers need to support audio/video multimedia conference to hold, and do not have other specific demand.Wherein, core net 105 is used to transmit monitors the signaling of answering between terminal 102 and the application server 103, can be IMS (IP Multimedia System) core net or SS (Soft switch) core net.
Preferred embodiment as shown in Figure 2 is the method flow diagram that is used for the audio/video multimedia conference Lawful Interception.May further comprise the steps:
Step S1, be provided with one monitor control end, terminal, application server, media server are answered in a monitoring;
Step S2, the user initiates the Lawful Interception request by monitoring control end to application server, has the meeting that will monitor number in the request and answers termination number;
Step S3, after application server was received the Lawful Interception request, call monitoring was answered termination number, after terminal responds is answered in monitoring, application server is answered terminal with monitoring and is joined in the meeting of monitoring, and the user answers terminal by monitoring can monitoring audio/video multimedia conference; Can be provided with in force to monitor and answer terminal, not send medium, answer the audio/video multimedia conference that terminal influences normal users to avoid monitoring for receiving only medium.
Step S4, user are hung up and are answered terminal after Lawful Interception is finished, and application server will be answered terminal and be removed from meeting, and Lawful Interception finishes.
Be illustrated in figure 3 as each signaling interaction between devices flow process of snoop procedure.Audio/video conference between the conference member 1-n carries out according to normal signaling process.Interception request is sent to application server by monitoring control end, carries meeting number in the interception request and monitors the number information of answering terminal.Application server initiates to answer to monitoring the calling procedure of terminal, monitors and answers terminal responds, and media server carries out the medium of Lawful Interception under the control of application server handles, and makes to monitor and answers joining meeting to terminal, and meeting is implemented to monitor.After Lawful Interception is finished, monitor and answer hanging up terminal, under the control of application server, terminal is answered in monitoring and shift out meeting.And this moment, normal conference process still carried out, and each conference member can't perception for the process of Lawful Interception.
By technique scheme provided by the invention, realized flexible finishing apace in the audio/video multimedia conference business in the IMS and the NGN communications field, utilize existing device and function to realize the function of Lawful Interception, the Lawful Interception behavior is transparent fully to the normal member of audio/video multimedia conference simultaneously, can not influence the use of normal member in the multimedia conferencing, the audio/video multimedia conference member can not perceive meeting and be monitored.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
