Addresses interchange procedure in mobility management architecture for IP-based IMT network platform (IP/sup 2/)

A mobility management architecture is proposed for IP/sup 2/. It manages routing information and location information separately. To support hierarchical mobility management, each management function is separated into a local part and a global part. This reduces the signaling overhead and the delay when updating routing information and location information. We also proposed an addresses interchange procedure. It hides the location information and movement information of communicating terminals. This makes it possible for mobile terminals to communicate at any time without the need to first recognize their locations or movements.
