Providing CALEA/LegaI Intercept information to law enforcement agencies for internet protocol multimedia subsystems (IMS)
Abstract:
A method and apparatus for providing useful packet data to a CALEA/Legal Intercept collection function. At an access point to a network such as the Internet, sources and destinations of data connections are examined to determine whether any of the bearer messages should also be routed to a CALEA/Legal Intercept monitoring system. If this condition is recognized, the bearer messages and corresponding signaling control messages are correlated in a call packet delivery application server and then delivered to a CALEA/Legal Intercept monitoring system. Advantageously, the monitoring receives as a bundled message set the bearer message and the control messages used to route and otherwise process these bearer messages.
