SESSION PROCESSING SYSTEM IN GGSN SYSTEM - THE PROCESSING SYSTEM IS COMPRISED OF PLURAL SIGNAL RECEIVING TASKS FOR RECEIVING SPECIFIC IPC(INTERNET PROCESSION COMMUNICATION) AND EVENT PROCESSING TASK

摘要

PURPOSE: A session processing system in a GGSN(Gateway GPRS(General Packet Radio Service) Support Node) system is provided to comprise dedicated tasks for processing specific signals, thereby processing GTP-C(GPRS Tunneling Protocol Control) at high speed without omitting IPC(Inter Processor Communication) between blocks. CONSTITUTION: A GNCC(GN Interface Connection Control) unit comprises a signal receiving task for exclusively receiving a PDP(Packet Data Protocol) context generation request message through an interface card from an SGSN(Serving GPRS Support Node), and a signal transmission task(52) for exclusively transmitting a PDP context generation response message received from a PSCC(PDP Context and Session Management Connection Control) unit(60) through a corresponding interface card. The signal receiving task performs a resource assign library call and a TEID(Tunnel End-point IDentifier) assign library call, and than transmits the PDP context generation message to the PSCC(60). The signal transmission task(52) receives the PDP context generation response message from the PSCC(60), and then transmits the response message to the SGSN through the corresponding interface card.
