The scope of the present invention is an information transfer system and a mobile station (10) connected to it. In a system according to the invention a mobile station (10) is connected to a terminal device (40) e.g. through either a cable or an infrared connection, and the radio parts of the mobile station (10) are switched off. Through the terminal device (40), a local network, ATM-network (70, 81, 80, 82) and a network server (90) the mobile station (10) is connected over a wired network to a mobile communication switching center (100) or to a telephone network exchange (110, 130). When the connection from the mobile station (10) to a mobile communication switching center (100) or to a telephone network exchange (110, 130) is broken, the mobile station (10) establishes a connection to a mobile communication switching center (100) by radio in the normal way through a base station (105) and a base station controller (104).
