This paper suggests the IP mobility which is independent with Mobile Terminal. A similar architecture had been ever proposed at other study group like IETF. Here, it applies IP mobility in accordance with macromobility procedure so that the terminals with legacy IP stacks have the same degree of mobility as a terminals with mobility aware IP stacks. This suggests the terminal mobility with using context transfer mechanism in discussion at the IETF and a new architecture for terminal mobility in wireless access networks.
