Abstract:
1. A method for intelligent signaling-router-based surveillance, the method comprising: at a signaling router capable of routing call-related signaling messages between users in a communications network: (a) receiving a call-related signaling message, the call-related signaling message being selected from a group consisting of signaling messages relating to the setup, progress, or tear-down of a call; (b) determining whether the message is associated with a user or device under surveillance by extracting at least one parameter from the call-related signaling and performing a lookup in a database local to the signaling router; (c) in response to determining that the message is associated with a user or device under surveillance, determining whether content-related or non-content-related surveillance is required; (d) in response to determining that content-related surveillance is required, forwarding the signaling message to a call server; and (e) in response to determining that non-content-related surveillance is required, copying data from the signaling message and forwarding the data to a delivery function.
