End-to-end network surveillance
First Claim
1. A method of providing network surveillance for a call having associated signaling units, said method comprising the steps of:
- setting to a predetermined state at least one bit within signaling units pertaining to said call, said call traversing a plurality of network elements; and
in response to said at least one bit with said predetermined state, transmitting to a processing element representation of signaling units exchanged between said network elements traversed by said call,said call being monitored on a substantially end-to-end basis.

Abstract
A method and architecture for end-to-end surveillance of network systems is disclosed. Comprehensive and rapid fault detection, fault segmentation, and self-testing of network elements are accomplished by utilizing a bit position in message signal units to indicate the surveillance of a particular call. When the surveillance bit is set, message signal units related to the selected call are copied and forwarded to a processing element. The processing element correlates message signal units received to afford fault analysis and fault segmentation of network failures on an end-to-end basis. Additionally, the method and architecture may permit quality control for the network system by utilizing information within the message signal units received by the processing element.
