Patent ID: 6957262

Claim:
A system comprising a sever and a plurality of networks that are separately connected to said server; wherein each said network includes at least one mobile terminal primarily assigned to said network as its home network that receives preselected data from said server and outputs the received preselected data, said at least one mobile terminal being movable from its primarily assigned network to another of said plurality of networks, a communication device that sends said preselected data received from said server to all mobile terminals primarily assigned to any of said plurality of networks located within a range of communication of said communication device wirelessly, and a detection device that detects any said mobile terminals primarily assigned to any of said plurality of networks present within said range of communication of said communication device by detecfing said output of said received preselected data therefrom; and wherein said server includes a communication circuit that communicates with the communication device and the detection device included in each said network, a storage circuit connected to said communication circuit, said storage circuit storing in the form of a management table for each mobile terminal (i) information specifying the network in which that mobile terminal is currently located based on information received from said detection device and (ii) prestored information specifying the home network of that mobile terminal, and a control circuit connected to said communication circuit and to said storage circuit, said control circuit being adapted to receive data and information including a vortion indicating a specified mobile terminal primarily assigned to one of said plurality of networks as the destination of a remainder of said received data and information, and to control said communication circuit such that it sends said remainder of said received data and information to the specified mobile terminal based on information concerning the specified mobile terminal contained in said management table.
