摘要： A relay device acquires and stores address binding information indicating correspondence between a static communication address and a dynamic communication address of a mobile terminal which is linked to the relay device. The relay device also stores address binding information of other mobile terminals to which packets are sent from the source terminal. A management server stores the address binding information pertaining to the source terminal, and also stores the communication status information of the other mobile terminals with which the terminal is communicating. When the terminal terminates communication, the relay device and the server delete the address binding information pertaining to the source terminal by cooperating with each other.

摘要： A communication system 32 is provided with access routers 14, a location information management server 20, and a route optimization server 18. The route optimization server 18 receives a BU message from a Mobile-IP terminal 12A and receives location information of a connected access router 14A from the location information management server 20. Then the route optimization server 18 transmits the BU message to the connected access router 14A, based on the received location information of the connected access router 14A, whereby the connected access router 14A to which the communication terminal 12 is connected is notified of route optimization information. This permits the connected access router 14A to relay a packet transmitted and received between the Mobile-IP terminal 12A and the communication terminal 12, through an optimal route.

摘要： The problems of an additional load to an AR having the function of transferring a packet, a BR functioning as a border relay device, and an address management server, a packet loss due to an unnecessary inquiry to the management server, an increasing delay of a packet transfer, etc. can be reduced. According to the address identification information for identification of the type of an address, routers determine to which type the address assigned to a given packet belongs, a terminal identification address for identification of a source terminal and a destination terminal, a packet transfer address for transfer of the packet to another router, or an address requiring no address conversion. Thus, an address conversion network connected to an external IP network can be realized, an increased load by an inquiry about an erroneous address, etc. and a packet loss and delay due to an unnecessary inquiry can be reduced.

摘要： Determining a cross over router on the occasion of a migration of a mobile terminal connected to a network during communication in the network. A path control device receives path control information from each router in the network and stores the information as a path control table. Then, a pre-migration path between the mobile terminal and the correspondent terminal is recognized and, on the occasion of a migration of a mobile terminal, the path control device predicts a post-migration path between the mobile terminal and the correspondent terminal. The path control device then compares the pre-migration path and the post-migration path to derive as a common part, and a router closest to the mobile terminal in the common part is determined as a cross over router.
