Title: METHOD AND DEVICE FOR IDENTIFYING VISITED AND HOME AUTHENTICATION SERVERS
Abstract:
Authentication problems often occur when a user of a terminal visits a communications network while roaming. The invention therefore relates to a method for authorizing an authenticated user of a communications terminal, the terminal (UE) being intended to connect to a packet-switching network via an access gateway (AGW) over a common network to which the terminal is connected, the method being implemented by a common authentication server (vAAA) over the common network and including the following steps: receipt (v302) of a user authorization request from the access gateway (AGW), including an identifier of the user; transmission (v307) of a user authorization response to the access gateway (AGW), including parameters for authorizing the user, and a unique identifier of an authentication server that authenticated the user (hAAA).
