Wireless access control method and wireless access system

Abstract

A newly developed IP layer technology can be applied to a wireless access network without a wireless base station adding or amending the new IP layer technology to a wireless region specific signal. The wireless base station transfers to a wireless access gateway a communications establishment request signal from a mobile terminal without conversion. When the mobile terminal which is the source of the communications establishment request signal is not permitted to communicate with equipment external to the wireless access network, the wireless access gateway transfers the communications establishment request signal to an access network control station. The access network control station continues communications with the mobile terminal, determines whether or not the communications between the mobile terminal and equipment external to the wireless access network is to be permitted based on the communications between the access network control station and the mobile terminal. When the communications between the mobile terminal and the equipment external to the wireless access network is permitted, it transmits a communications establishment permission signal to instruct the wireless access gateway to establish a channel between the mobile terminal and the equipment external to the wireless access network.
