Filed: 2002-12-30
Abstract: PURPOSE: A method for processing a user traffic of a GSN(GPRS(General Packet Radio Service) Support Node) is provided to offer a ceaseless packet service by preventing packet service failure. CONSTITUTION: If a user traffic is received to a GSN after session information is set up, an IP processor(21) attaches a sequence number to the received sequence number and transmits it to a primary GTP-U(GPRS Traffic Protocol-User) processor(23a) and a backup GTP-U processor(23b) through an ATM interface unit(22) at the same time. The primary GTP-U processor(23a) searches for the session information of a relevant user traffic using the TEID(Tunnel Endpoint ID) of the received user traffic as a search key and processes the user traffic by using the searched session information. In case that session information is contained in the received user traffic, the primary GTP-U processor(23a) updates session information, such as statistical information, billing information, a finally received sequence number, etc. The backup GTP-U processor(23b) checks the sequence number attached to the received user traffic. If the sequence number is not the next number of the most recently received and stored sequence number, the backup GTP-U processor(23b) sends a session information backup request to the primary GTP-U processor(23a).
