In this paper, a ticket ID system is proposed for service agent based WLAN/cellular network integrated service architecture. The proposed system accelerates the authentication process for the mobile terminal in the visited network, which effectively compensates the additional cost introduced by the service agent. The design of the ticket ID system also considers the user anonymity feature of the integrated service architecture. The performance evaluation demonstrates the ticket ID system effectively reduces the overall overhead in service agent based integrated service architecture.
