Monitoring Architecture for UMTS Networks

Monitoring of a suspects' personal communications can be a very effective evidence collection mechanism in criminal investigations. Existing packet sniffer and protocol analyzer applications have limitations in their usefulness with the rapid development of wireless networks. This research outlines a monitoring architecture, which is suitable for the UMTS networks. It works on Gn interface, FPGA is used for packet sniffer and generator, following with packet parser. Experiments show the effectiveness of this architecture.
