Title:

METHODS AND SYSTEMS FOR INTELLIGENT SIGNALING ROUTER-BASED SURVEILLANCE

Document Type and Number:

WIPO Patent Application WO2003088507

Kind Code:

A3

Abstract:

Methods and systems for intelligent signaling-router-based surveillance are disclosed. A surveillance and signaling router (100) receives call signaling messages, identifies call signaling messages associated with user under surveillance type for the call signaling messages. If the surveillance type is content-related, the surveillance and signaling router forwards the message to a call server (108). The call server replaces parameters in the message and in subsequent messages so that the call is transparently set up trough a media proxy server (110). The media proxy server copies the media stream to a delivery function. If the surveillance type is non-content-related, the surveillance and signaling router sends a copy of the message or information extracted from the message to an external device.
