Implementation Method, System and Device of IMS Interception

An implementation system of IP multimedia subsystem (IMS) interception, comprising a content of communication trigger function (CCTF) and a content of communication internal interception function (CC-IIF), wherein

• the CCTF is adapted to control the CC-IIF to allocate media anchor points to communication parties, and control the CC-IIF to copy the communication content to complete interception of the communication content when the communication parties communicate through the media anchor points;
• and
• the CC-IIF is adapted to allocate the media anchor points to the communication parties and copy the communication content when the communication parties communicate through the media anchor points.

An implementation device of IP multimedia subsystem (IMS) interception, comprising:

• a first control module, adapted to control a content of communication internal interception function (CC-IIF) to allocate media anchor points to communication parties;
• and
• a second control module, adapted to control the CC-IIF to copy communication content when the communication parties communicate through the media anchor points to complete interception of the communication content.

An implementation device of IP multimedia subsystem (IMS) interception, comprising:

• an allocation module, adapted to allocate media anchor points to communication parties;
• and
• a copying module, adapted to copy communication content to complete interception of the communication content when the communication parties communicate through the media anchor points.
