Abstract
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.
