GTP Inspection Overview

GPRS provides uninterrupted connectivity for mobile subscribers between GSM networks and corporate
networks or the Internet. The GGSN is the interface between the GPRS wireless data network and other
networks. The SGSN performs mobility, data session management, and data compression (See

The UMTS is the commercial convergence of fixed-line telephony, mobile, Internet and computer
technology. UTRAN is the networking protocol used for implementing wireless networks in this system.
GTP allows multi-protocol packets to be tunneled through a UMTS/GPRS backbone between a GGSN,
an SGSN and the UTRAN.
