Abstract
Abstract The invention relates to an integrated data transfer system, the extensive basis of which is constituted by a general cellular radio system, preferably the GSM system, and in which a radio local area network, preferably the HIPERLAN network, is used for communication between data terminals (3a, 3b, 3c, 3d, 3e, 3f) in small areas with dense communications. In addition, the Internet network (6) is used for fast data transfer. The connection between networks is controlled and handled by a gateway computer (1) located in each radio local area network. In view of the cellular radio system, the gateway computer operates like a base station controller (BSC). The radio local area network consists of the coverage areas or cells (4b, 4c) of the data terminals, and it can be formed, changed and dissolved freely. The computer terminals (3c) preferably have an Internet address enabling mobility, whereby the gateway computer (1) handles the routing to the nodes of the network and the mobile Internet nodes visiting it. In a home or small office environment (HE) there can be formed a small-scale radio local area network, the gateway (10) of which is by means of an existing connection and the corresponding general data transfer network (8) connected to a certain, larger local area network, preferably located in an office environment.
