Title:
A SYSTEM, METHOD AND NETWORK EQUIPMENT FOR IMPLEMENTING THE LAWFUL INTERCEPTION IN NEXT GENERATION NETWORK
Document Type and Number:
WIPO Patent Application WO/2007/082435
Kind Code:
A1
Abstract:
A system, method and network equipment for implementing the lawful interception in
next generation network comprise: join the lawful interception service application server
in the call signaling routing, join the lawful interception media gateway function
entity in the media routing, and the lawful interception media gateway function
entity gathers and forwards the lawful interception communication content.
Because it is independent of the access network that gathering and forwarding the
lawful interception communication content on the lawful interception media gateway
function entity, the present invention can implement lawful interception for
the calls of the users accessing through the fixed network or the mobile network in
next generation network, and the problems that the trust and authorization of
the session control layer and the access layer are avoided, thereby, a integrated and
feasible solution for gathering the lawful interception communication content
is provided for next generation network.
