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 mobile communications network and data delivery method in a mobile communications network is provided that can implement connectionless transfer in the mobile communications network, and obviate the need for sending a call control signal for data delivery. An IP address is assigned to each of the nodes of the mobile communications network including routing nodes (a gate node and repeater node, for example) and edge nodes and to each mobile station. A routing node, receiving data including the IP address of a mobile station, carries out routing of the data in accordance with routing information. The edge node that receives the data routed by the routing node, transmits the data to the mobile station corresponding to the IP address of the mobile station added to the data. The IP addresses are also applicable to delivering data to users of the same group, or carrying out control like handover.
