A Hybrid Network/Host Mobility Management Scheme for NGNs

Next Generation Networks are becoming more and more converged. Like the System Architecture Evolution (SAE) which encourages Fixed Mobile Convergence. It is a packet switched network which connects different radio access technologies. With this heterogeneity, mobility management becomes an issue as the goal is to always achieve seamless mobility. However, various access technologies support different layer 3 schemes, such as PMIPv6 which is network-based and MIPv6 which is host based. With the heterogeneity that the SAE adopts, there are several deployment scenarios where PMIPv6 will interact with MIPv6. We propose a hybrid network/host mobility management scheme which will allow the user to roam amongst networks supporting either protocol.
