MOBILE ROUTER, POSITION MANAGEMENT SERVER, MOBILE NETWORK MANAGEMENT SYSTEM, AND MOBILE NETWORK MANAGEMENT METHOD

摘要

When connected to an external network (7), a mobile router (5) checks an address table if a home address is allocated. If it is not allocated, the mobile router derives the address of a position management server from a position-management-server address table and sends an allocation request message to the position management server (2). The position management server (2) receives an address management table listing addresses to be allocated to each mobile network (4) and the allocation request message sent from the mobile router (5), searches the address management table for an unused address, and sends an allocation permission message to the mobile router (5) to automatically allocate a home address to the mobile router (5).
