Integral radio communication system and communication method

PROBLEM TO BE SOLVED: To provide a data transfer system integrating a general cellular radio network and a multi-user radio local network. SOLUTION: A radio LAN is used for communication among data terminal equipments 3a-3f in a small district with high communication density. Furthermore, an internet communication network 6 is used for high speed data transfer. The connection among networks is controlled and processed by a gateway computer 1 located to each radio local area network. The gateway computer 1 processes path designation to the network node and a moving internet node visiting the network node. A small scale radio LAN is formed for an environment of a home or a small scale office. The gateway 10 is connected to LAN located in a larger scale or preferably in an office environment by the existing connection and the corresponding general data transfer network 8.
