Patent ID: 7453817

Claim:
A system for correlating signaling traffic for service sessions in a packet service network, the system comprising: a central traffic correlation system (CTCS) configured to receive a correlation request for a first service session from a client device, transmit a collection request for the first service session to a first traffic collection system (TCS) and a second traffic collection system (TCS), receive a first collection response from the first TCS indicating first data for the first service session, receive a second collection response from the second TCS indicating second data for the first service session, and transfer a correlation response to the client device indicating the first and second data; the first TCS configured to monitor and store first signaling traffic for a first network region, receive the collection request from the CTCS, process the collection request to retrieve the first data for the first service session from the first signaling traffic, and transmit the first collection response indicating the first data to the CTCS; and the CTCS further configured to process the correlation request to select the first TCS and the second TCS and generate the collection request, and process the first data and the second data to generate the correlation response.
