VIP (VHE in Mobile IP networks) Architecture

In this study we propose a new architecture named VIP (VHE in mobile IP networks) which guarantees authorized user access and user mobility management. The main goal is to bring the VIP architecture closer to the current GSM networks. To achieve this goal our architecture is based on LDAP and RADIUS services. VIP is able to ensure user’s mobility across different IP domains. For the transportation of personalized services across different networks VHE (Virtual Home Environment) is employed. VHE gives a set of recommendations for providing users their home environment in foreign networks. The VHE services are activated to transport the user’s profile between the home and the foreign network.ou
