Title: Method for address management of IMT-2000 asynchronous mode
Inventor: KWON HYE YEON
IPC: H04L12/28
Filed: 2001-09-24
Abstract: PURPOSE: An asynchronous address management method for an IMT-2000(International Mobile Telecommunications-2000) mobile communication network is provided to perform a networking using a PPP(Point-to-Point Protocol) between a TE(Terminal Equipment) and an MT(Mobile Terminal) in a PT(Packet Terminal) of the asynchronous IMT-2000 mobile communication network and accommodate a static or dynamic IP(Internet Protocol) system using a mobile IP and a simple IP as a domain. CONSTITUTION: An SM(Session Management) layer receives a packet data protocol generation request for a packet service, and transmits a signal channel setup request message to a PMM(Packet Mobility Management) layer of a PT in case that a signal channel connection is not set up. The PMM layer of the PT requests the connection of an RRC(Radio Resource Control) layer and the Iu connection of an RNC(Radio Network Controller) and a core network, and transmits a subscriber registration request message to the RRC layer for providing a packet data service to an object core network. If the subscriber registration request message is transmitted to the core network from the RRC layer through an SGSN/GGSN(Serving GPRS(General Packet Radio Service) Support Node/Gateway GPRS Support Node), an address management server of the core network transmits a response message of the Iu connection and a subscriber registration result message to the RRC layer and the PMM layer of the PT through the SGSN/GGSN. The PMM layer of the PT transmits a subscriber registration and signal channel connection response message to the SM layer. The SM layer transmits a packet data protocol generation request message to a server of the object core network through the SGSN/GGSN using a packet data protocol address previously received in an MT. The server receives the packet data protocol generation request message, and assigns a subscriber address. In case that the subscriber address is a static address system, the server determines an address of the PT as an address requested by the PT. If the subscriber address is a dynamic address system, the server determines the address of the PT as an address assigned in the address management server. If the address of the PT is determined, the address management server transmits a packet data protocol generation result including the subscriber address to the SM layer. The SM layer transmits the assigned address and the result about a packet service call process requested in the PT to a PPP of the MT.
