Recently, wireless Internet service has become generalized, and required the user authentication of a mobile hosts and QoS. However, time required for user authentication during handoff Processes between a wireless LAN system and mobile hosts is long, and is unsuitable for real-time communication and multimedia applications. In this paper. we improved the existing system in order to reduce a lead time of user authentication as they extended a Fast Inter-AP handoff. We use a Mechanism to assume a confidence degree with bases by the time that stayed at individual wireless LAN systems in order to reduce the handoffs. The experiment network shows that it decreases communication load, and improves communication QoS.
