Global Mobility: The Key Enabler for Next Generation Networks (NGN)
Global Mobility is one of the invigorating issue for Next Generation Networks (NGNs). To facilitate user roaming over NGNs, there must be an effective and efficient Global Mobility Management mechanism, so that the mobile connection with its current serving network is handoff to its target network to maintain service continuity without the need to disconnect and reconnect. Therefore, the authors propose a novel architecture that can be deployed in NGNs. Second they propose a predictive and adaptive Network Switching Decision Mechanism (NSDM) that optimizes the switching initiation time as well as selection of the most optimal network.
