Abstract

In order to construct a cellular data network for the next generation mobile communication service, IP layer mobility support becomes essential. IP layer mobility support such as Mobile IP(MIP) is suitable for the global Internet environment. However, when we use MIP infrastructure for the cellular data network, we must consider the fast hand-over for rapid data transfer, and load balancing problem due to the location changes. In order to solve these problems, Mobile IP Working Group is suggesting some architectures supporting micromobility. In this paper, we define a cellular data network that supports micromobility. and we design a cellular packet network structure considering the micromobility. The proposed network and the design of Mobile IP extension support seamless regional registrations in multi-level hierarchical topology. They accept the differential mobility management strategy as well.
