Abstract: A method for the operation of a radio system (28) includes muting, the fixed station (25) of the radio system (28) when no operable mobile telecommunication terminal (30) is located in its coverage area (20). A system to execute the procedure comprises a fixed station (25) for the radio system (28) and a mobile telecommunication terminal (30) suited to communicate with the radio system (28). The fixed station (25) has a circuit to detect an operable mobile telecommunication terminal (30) in its coverage area (20) and a circuit to mute the transmitter of the fixed station (25), depending on the state of the detection circuit.

Abstract: A system of digitally operating cordless telephone including a fixed station (20) connected with the common net (11) and several freely movable mobile stations (30.1 to 30.4). The naturally provided functional area (22) of the system can be enlarged by using a relay station (40). For this purpose the relay station (40) can permit the retransmission of transmission packages arriving from the fixed station (20) without changes to further mobile stations (30.5, 30.6) in a further functional area (23). In the other direction, the relay station (40) forwards respective packages arriving from the further mobile stations (30.5, 30.6) to the fixed station (20). For this purpose the relay station (40) maintains transmission channels, which are associated with each other in pairs and are chronologically very closely coupled, to the fixed station (20) as well as to the further mobile stations (30.5, 30.6) in accordance with the DECT Standards (Digital European Cordless Telecommunications).
