ADDRESS PROVIDING SYSTEM AND CONSECUTIVE COMMUNICATION SYSTEM TO MOBILE TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a system for momentarily providing an address to a mobile terminal and allowing the mobile terminal to continue communication when the terminal moves between base stations and between sub-nets if it is estimated that the mobile terminal connected to the sub-nets mutually interconnected by using the Internet protocol through the dedicated short range communications is mounted on an automobile or the like and moved.

SOLUTION: The system of this invention lends an address to a base station in advance in order to momentarily provide the address to the terminal. Further, gateways of each sub-net manage addresses which all the gateways lend in order that the communication of the terminal is consecutive even when the terminal moves between the sub-nets. Moreover, the gateways retransmit deletion of records in the case of registering the IP address and a host name in order to prevent the same host name from being duplicated and registered to a dynamic DNS (Domain Name System) in different addresses.
