PURPOSE: A GTP fast processing unit in a GPRS(General Packet Radio Service) network is provided to reduce loads of processors by processing specific packet in a GTP switch, thereby improving transmission rate of user traffic. CONSTITUTION: A GTP(GPRS Tunneling Protocol) switch table(500) stores large amount of TEID(Tunneling Endpoint Identifier) switching information to tunnel user data of a plurality of terminals. A GTP switch module(600) searches for the corresponding switching information in the GTP switch table(500) for executing TEID switching to the user data. A GTP filter(700) switches packet received from a physical layer(100) to an IP module(300) if the packet is control information, and switches the packet to the GTP switch module(600) if the packet is user data. A switch driver(800) takes charge of interface between the GTP switch module(600) and the GTP filter(700). An application program matching part(900) updates the corresponding TEID switching information in the GTP switch table(500) if receiving TEID switching update information from a GTP control block(10).
