MOBILE COMMUNICATION METHOD, MOBILE COMMUNICATION APPARATUS, HOME AGENT APPARATUS, ACCESS ROUTER INFORMATION SERVER APPARATUS, AND MOBILE COMMUNICATION SYSTEM

摘要

A mobile communication apparatus (20) comprises a mobile IP/high-speed mobile IP processing part (25); an access router searching part (28) for acquiring information related to access router apparatuses; a high-speed mobile IP compliance determining part (27) for determining whether the access router apparatuses comply with a high-speed mobile IP; and a high-speed mobile IP control part (26) for controlling the contents of a message produced by the mobile IP/high- speed mobile IP processing part (25). According to this, even if any of access router apparatuses does not comply with the high-speed mobile IP, the procedure of high-speed mobile IP can be implemented, thereby reducing packet loss.
