Abstract:
The roaming between different WiMax (Worldwide Interoperability for Microwave Access) networks as well as the interworking between WiMax and other access technologies will be a key enabler for global WiMax deployment. To provide secure and seamless roaming capability for mobile users across different access network domains, belonging to the same or different operators, we propose a roaming & interworking solution using intermediary entities, called roaming interworking intermediary (RII). A generic RII-based interworking and roaming architecture between WiMax, 3GPP (third Generation Partnership Project) and WLAN networks is presented. A test-bed has been setup, using real pre-WiMax and Wi-Fi equipments and real operational cellular network, to demonstrate and evaluate the proposed solutions. The robustness, feasibility and efficiency of the proposed architecture are proven through different user scenarios.
