Abstract: A method and a system of providing information transfer between at least one data unit and a central server. A data unit in an area within which at least partly two different communication means have an overlapping coverage, transfer information with the central server by means of one of these communication means. Selection of one of the communication means is done from a plurality of parameters governed by a data unit profile. The central server in turn will in most applications be interconnected to one or more users and their applications by means of a further communication network, such as the internet. A user will thus communicate with the central server by means of a single communication network and method even though several different communication networks and methods are used for information transfer to and from the data unit or units.
