摘要:A method and apparatus for providing useful packet data to a CALEA/LegalIntercept 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 ofthe bearer messages should also be routed to a CALEA/Legal Intercept monitoringsystem. If this condition is recognized, the bearer messages and corresponding signalingcontrol messages are correlated in a call packet delivery application server and thendelivered to a CALEA/Legal Intercept monitoring system. Advantageously, themonitoring receives as a bundled message set the bearer message and the controlmessages used to route and otherwise process these bearer messages.
