Abstract
To reduce change on a cellular network side required at the time of utilizing a cellular network by way of an IP network. A radio terminalputs a location registration message for a cellular networkon an IP packet, and sends the message to an access point. This IP packet is transferred to a control proxy server. The control proxy serverstores a correspondence between identification information on a radio terminal and an IP address based on a location registration request. If necessary, the location registration request is converted into the location registration message in compliance with a standard of the cellular network. The location registration message is transferred to an MSC/VLRvia a gateway. As the gatewaylooks like an ordinary base station to the MSC/VLRand an ordinary location registration message is usable, any change on the cellular network side is not necessary.
