SYSTEM AND METHOD FOR MINIMIZING OF HANDOFF INTERRUPTION TIME BY OPTIMIZING IP ADDRESS ASSIGNMENT PROCEDURE DURING HANDOFF FOR USE IN HIGH-SPEED PORTABLE INTERNET NETWORK
SYSTEM AND METHOD FOR MINIMIZING OF HANDOFF INTERRUPTION TIME BY OPTIMIZING IP ADDRESS ASSIGNMENT PROCEDURE DURING HANDOFF FOR USE IN HIGH-SPEED PORTABLE INTERNET NETWORK
The present invention (Mobile Subscriber Station) MSS for transmitting and receiving related to a delay time minimizing system and method due to the handoff on the optimization of the IP address assignment procedure according to the hand-off from the high-speed portable Internet network, the ranging message (Ranging Message) and RNG_REQ (Ranging Request) Compare PZID receiving the message receives, and their PZID of the MSS IP Address change or update procedure is required to include PZID (Packet Zone Identification) of the serving BS of the old (current) from the MSS after it is determined whether high-speed portable Internet, which comprises a target BS (target Base Station) that transmits RNG_RSP (Ranging Response) message containing the IP Address renewal Reuired indicating necessity result of the change or update procedure of the IP Address to the MSS network in minimal delay due to the handoff on the optimization of the IP address assignment procedure according to the hand-off system And a method.; According to the present invention, in that the target BS can omit the IP Address change or update procedure whether or not to pre-determine an extra IP Address change or update procedure by giving to notify the MSS performs, in the end to minimize service delay due to the handoff .
