<p>A policy control device (9) is installed as a gateway to a 3GPP network (7) between a WLAN-AP (4) and authentication server (5) in a WLAN network (2). On the basis of the type (EAP type) of authentication method of an authentication message transmitted from a WLAN terminal (1), the policy control device (9) determines whether to transfer the authentication message to the 3GPP network (7) or to the WLAN network (2) or an ISP network (3), and transfers the authentication message to the determined transfer destination network. Since this allows only EAP-AKA authentication messages to be transferred to the 3GPP network (7), the processing load on an intra-3GPP authentication server (8) reduces.</p> |
