摘要： There are provided a method, a network system, and a router capable of decreasing the chance of VRM or VLM changes so as to reduce signaling, and consequently contributing to better scalability. The method is applied to mobility management used in an IP-based network system, which contains a plurality of access routers (AR), location managers (LM) and routing managers (RM), through which a mobile node (MN) transmits and receives information. According to the method, a visited routing manager (VRM) where the MN is currently located monitors the MN, an AR currently communicating with the MN discriminates whether or not the MN is moving out of its connectivity range, and the VRM discriminates whether or not the MN is moving out of its control range. Then, the method switches mobility management over from the current AR to a new AR in accordance with the discrimination results, and switches mobility management over from the current VRM to a new VRM in accordance with the discrimination result.

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： In a network configuration in which a mobility control node is placed in the network, a packet is forwarded from a communication partner to the mobility control node by a basic IP mobility protocol for supporting movement in a local network managed by the mobility control node, a movement of a mobile terminal device across local networks formed by mobility control nodes is achieved without adding a function to the mobile terminal device. A mobility control node to be provided to the mobile terminal device is identified by a trigger reporting a movement has been performed to the network from the mobile terminal device, and, in the case of HO across between mobility control nodes, network information before the movement is reported instead of network information to be originally reported. Thus, the mobile terminal device determines that the movement is in the same network and can continue communication without performing an address generation procedure.

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.
