Abstract

A release is carried out by PP transmitting CC-person who belongs to a radio system with a short range, for example a wireless telephony system, can be temporarily transferred as guest into a second wireless telephony system. When the user moves to a second communications system, he identifies himself in it as a guest. Information relating to the temporary address of the relevant person is transferred to his home system. An incoming call to the person in question is received by the home system which forwards the call to the system in which the person sought is temporarily registered. The caller is then notified that a call is coming in by a call signal being originated. The called party then answers the call and a normal call is set up. With an outgoing call, signals are transferred from the caller to the network which registers who is establishing the call. The registration is carried out on the basis of a call occurring from a certain subscription, or person, regardless of whether the call is established from the home system or as guest in another system. The system then registers the length of the call and debits the subscriber at his home address.
