Abstract
A wireless communication network monitoring system for use in performing a user specified trace of signaling messages associated with a mobile call is disclosed. A central processing platform creates and distributes signaling message filter criteria information to a plurality of link monitoring modules (LMM). The filter criteria are asserted at a LMM and a matching signaling message is copied and subsequently transmitted to the central processing platform. Central processing platform receives the matching signaling message and uses information contained therein to create and distribute a second signaling message filter criteria. In such a manner, a call trace sequence is compiled and displayed. A billing subsystem is also disclosed and is adapted to generate a billing record based on information contained with one or more of the messages associated with the call trace sequence.
