Presently, while the various accesses come out, it is necessary to have the separate authentication process if it wants to connect to each access. The various accesses are accommodated in the future NGN leading in ITU-T and TISPAN. Service providers become to provide a service based on them. The important access network is the XDSL, WLAN, WiMax and WCDMA. The ongoing wireless LAN standardization and R&D activities worldwide, which target bit rates higher than 100 Mb/s, combined with the recent successful deployment of WLANs in numerous hotspots justify the fact that WLAN technology will play a key role in wireless data transmission. Cellular network operators have recognized this fact, and strive to exploit WLAN technology and integrate this technology' into their cellular data networks. In order that the service continuity is guaranteed while crossing the access network, the mobility management technology and integrated authentication and authorization technology are needed. In order that the seamless handover is provided, the various modes which are the same as those of the fast handover are considered. However, it has an effect that it is moreover many with authentication process. In this paper, we suppose that the various accesses are passed through. We propose for a single-sign-on for crossing from various accesses to the service level about the efficient integrated authentication technology. We focus on these interworking mechanisms, which effectively combine the various data access networks into integrated fixed, wireless and mobile data environments capable of ubiquitous data services and very high data rates in hotspot locations..
