<p>PROBLEM TO BE SOLVED: To enable information to be fetched under comfortable environments by arranging a particular communication identifier in plural information distribution service communication networks which have the same communication network identifiers, providing a path control function for mutual connection of the service communication networks, and providing a particular communication terminal identifier for each information distribution device discrimination on the mutual connection communication network. SOLUTION: Information distribution devices 60A to 60C which have the same communication terminals and identifier for particular communication terminals have the same communication network identifiers and the particular communication network identifiers, and a system is constituted by providing the devices in information distribution services communication networks 50A to 50C mutually connected to one another by way of communication network exchanges 40A to 40C having path control functions for other communication networks and mutual connection. Then, the only connection path is decided by the path control function of an exchange 40, there is no simultaneous connection to or connection incapability to plural communication networks 50, and transmission of one communication network 50 is enabled. Since there is an information distribution device 60 of a communication terminal identifier in the communication network 5, unique decision of the distribution device 60 corresponding to a user terminal device 10 is enabled.</p> |
