Apparatus and method for producing a tunnel in an integrated serving general packet radio service (GPRS) service node (SGSN) and gateway GPRS support node (GGSN) in a universal mobile telecommunication service (UMTS) network

摘要

An apparatus and a method are provided for producing a tunnel in an integration serving node formed by integrating a serving support node and a gateway node which connect a radio network controller of a wireless access network server to a home server of an external network. The apparatus comprises a plurality of integration traffic modules for processing upstream data and downstream data; a memory module comprising a look up table, for example, for storing integration tunnel endpoint identifiers corresponding to the integration traffic modules; a serving support node signaling module for, according to a call request of a terminal for connecting with an external server, selecting one integration traffic module from among the plurality of integration traffic modules and assigning an integration tunnel endpoint identifier corresponding to the selected integration traffic module; and a gateway node signaling module for receiving request data including the assigned integration tunnel endpoint identifier from the serving support node signaling module though internal processing communication (IPC) and storing the integration tunnel endpoint identifier in the look up table.
