Abstract: By automatic, direct point-to-point communication (N2) according to the invention, e.g. by means of Bluetooth, without involving a central server two terminals (T1, T2) establish which of the terminals (T1, T2) should preferably communicate with a transmission network (N1) and register only one of the two terminals (T1, T2) in the transmission network (N1). The terminals (T1, T2) are mutually identified as terminals belonging to a pool of terminals of a subscriber and, as well as the list of terminals of the pool, also have stored, for example, an order of precedence. The order of precedence is similar to an allocation of priorities. If two terminals (T1, T2) are located in a Bluetooth network (N2) they are mutually identified. If one terminal (T2) establishes that the priority assigned to the other terminal is lower than its own it logs on in a transmission network (N1) assigned to it by registering or remains registered in so far as it already was registered.
