An Overview of Macro-Mobility Management in Next Generation All-IP Based Wireless Network Infrastructures

Next generation wireless systems are most likely to have an IP based core network. Mobile IP is a proposed standard of the IETF (Internet Engineering Task Force) designed to assist different mobile users. Mobile IP provides an elegant solution for node mobility when the mobile node infrequently moves. However, it implies a relatively large overhead and delay, due to indirect communications. In this paper, three macro-mobility management architectures based on different layers are reviewed, first of which uses Mobile IP to manage mobility for non-real-time communications, the second is based solely on SIP, while the third is based on a new solution introducing third party to manage macro-mobility. Finally, the most suitable architecture for macro-mobility management is proposed
