Abstract
Methods and systems for providing mobile subscriber surveillance identify certain call signaling messages as candidate messages for mobile subscriber surveillance. From the candidate messages, messages associated with mobile subscribers under surveillance are identified. Mobile subscriber location information is obtained for the messages associated with the mobile subscribers under surveillance. The location information is forwarded to a surveillance center, such as a state or federal law enforcement or security agency. The original call signaling messages are forwarded to their intended destinations so that surveillance is performed transparently to the mobile subscriber under surveillance.
