Position identifier management apparatus and method, mobile computer, and position identifier processing method
First Claim
1. A position identifier management method for supporting movement of a mobile computer between networks, comprising:
- storing binding information concerning said mobile computer managed by a position identifier management apparatus in a storage means of the position identifier management apparatus, said binding information including a compatible node identifier for uniquely specifying said mobile computer and a compatible position identifier for uniquely specifying a position of said mobile computer on a network;
registering the binding information in said storage means in response to a registration request to register the binding information; and
transmitting the binding information in response to a query about the binding information concerning said mobile computer when said binding information is stored in said storage means,wherein the compatible node identifier of said mobile computer comprises a first virtual network identifier assigned to said mobile computer which moves between networks and a node identifier for uniquely specifying said mobile computer, and the compatible position identifier of said mobile computer comprises a second network identifier which is usable only by mobile computers assigned to a network to which said mobile computer is connected and the node identifier.

Abstract
When a first mobile node is moved, it reports binding information including a compatible node identifier (virtual mobile guaranteed general network identifier and a node identifier) and a compatible position identifier (mobile guaranteed real network identifier identified on a network to which the first mobile node is moved, and a node identifier) to a first server which is assigned to the first mobile node. A second mobile node also reports the binding information to a second server. For communicating with the second mobile node to which a second server is assigned, if the destination address of a packet addressed to the second mobile node is designated with a compatible node identifier, the first mobile node acquires the binding information of the second mobile node from the second server. Then, the first mobile node converts the destination address of the packet into the acquired compatible position identifier and sets the compatible position identifier of the first mobile node as the source address of the packet. The first mobile node then transmits the packet.
