Abstract
A method for the operation of a radio system ( ) includes muting, the fixed station ( ) of the radio system ( ) when no operable mobile telecommunication terminal ( ) is located in its coverage area ( ). A system to execute the procedure comprises a fixed station ( ) for the radio system ( ) and a mobile telecommunication terminal ( ) suited to communicate with the radio system ( ). The fixed station ( ) has a circuit to detect an operable mobile telecommunication terminal ( ) in its coverage area ( ) and a circuit to mute the transmitter of the fixed station ( ), depending on the state of the detection circuit. The mobile telecommunication terminal ( ) has a circuit to determine its position—preferably based on signals of another radio system ( 8)—and to check whether that position is basically located within the coverage area ( ) of a fixed station ( ) of the radio system ( ) with which it is entitled to communicate, as well as a circuit to execute a registration procedure which can trigger the activation of the radio system ( ).
