ABSTRACT:
In a mobile communication system, when a mobile station (PS1 to PSj) makes a request for connection to a service provider (SP), a base station (BS1 to BSn) acquires an IP address "IP1" assigned for the base stations and assigns to the requesting mobile station an IP address "IP2" for the mobile stations that has been acquired in advance in place of the IP address "IP1". When data transfer is started, the base station changes the source address in data sent by the mobile station from "IP2" to "IP1" and then transfers the resulting data to the service provider. On the other hand, the base station changes the destination address of data sent by the service provider from "IP1" for the base stations to "IP2" for the mobile stations for subsequent transfer to the mobile station.
