Mobility management is an important topic in wireless networks. Mobile hosts are subject to changing their point of attachment from his home network to another foreign network. In terms of personalized services, the network manager must know the user location by implementing a roaming mechanism. VHE (virtual home environment) provides to the users an identical computing network environment in a foreign network to the one in their home network. In this paper we propose an architecture that ensures authorized user access and user mobility management. This architecture also guarantees the management of personalized services of the user according to the VHE specifications. We introduce a new concept named "mobility service provider" (MSP) which manages user mobility. The mechanisms for user authentication, management and update of the user profile, are based on LDAP (lightweight directory access protocol) services. For authorized user access, RADIUS (remote access dial in user service) security services are used. Additionally to user authentication, the main goal is service adaptability regardless of the equipment utilized. The VHE services are able to convey the user's profile between the home and foreign network. We present in this paper an architecture that supports user mobility.
