- Abstract
- In order to overcome the drawbacks and combine the advantages of both 3G packet-switched mobile communication systems and WLAN, high-speed portable Internet (HPi) system based on 2.3GHz bandwidth and IEEE 802.16e has been developed in Korea. In these heterogeneous wireless networks, it is important for each wireless system to be backwardly compatible with other wireless systems and to be smoothly roamed. In order to provide wireless Internet service for users who roam to another wireless network, users should be authenticated and/or authorized. In this paper, we focus on providing authentication architecture for interworking between UMTS and HPi system based on EAP and Diameter for a mobile user authentication.
