System and method for lawful intercept detection of call data and call content
First Claim
1. A switch for use in a telecommunications network, the switch comprising:
- a call control function; and
a lawful intercept server, wherein the lawful intercept server is capable of receiving a lawful intercept message identifying a target device and, in response to a subsequent origination of a call associated with the target device, the call control function is capable of enabling a lawful intercept detection point associated with the call, and wherein, in response to an occurrence of the enabled lawful intercept detection point, the lawful intercept server is capable of transmitting a message indicating the occurrence of the lawful intercept detection point.

Abstract
A telecommunications switch receives a lawful intercept message identifying a target device and updates a subscriber database according to the message. Upon an origination of a call associated with the target device, the switch enables a lawful intercept detection point associated with the call. When the detection point occurs, the switch transmits a message indicating the occurrence of the detection point. The switch may include a service control point co-located with the switch. The lawful intercept message may be received from, and the message indicating the occurrence of the lawful intercept detection point may be transmitted to, a lawful intercept delivery function. Upon an origination of a call associated with the target device, the switch may also cause a media gateway to transmit call content from the call to the lawful intercept delivery function.
