Lawfully Authorized Electronic Surveillance (LAES) for 3GPP IMS-Based VoIP and Other Multimedia Services
|Publication Date:||1 May 2007|
This ATIS Standard defines an interface between a TSP and an LEA for the reporting of LAES for 3GPP IMS-based VoIP and other 3GPP IMS-based multimedia services. This ATIS Standard identifies specific United States requirements for the LI.
The main purpose of this ATIS Standard is to provide capabilities for support of LAES for VoIP. In addition, the scope also includes other IMS-based multimedia services because the media type may change in mid-session (e.g., audio to video, or video to audio). The mapping of SIP messages to  messages must take place from the beginning of a session because of the potential for a change to a VoIP call in the middle of a session.
