Kind Code:
A1
Abstract:
A policy control device (9) is arranged as a gateway to a 3GPP network (7) between a
WLAN-AP (4) in a WLAN network (2) and an authentication server (5) in a WLAN network. According
to a type (EAP type) of the authentication method of an authentication message
transmitted from a WLAN terminal (1), the policy control device (9) judges whether
a network of a transmission destination of the authentication message is to be
the 3GPP network (7) or the WLAN network (2) or an ISP network (3) and transfers the
authentication message to the decided destination. This makes only authentication messages
of EAP-AKA to be sent to the 3GPP network (7), which reduces the processing load
in a 3GPP authentication server (8).
