摘要： A method in a mobile radiotelephone system in which an address is added to a symbol message in a control channel in order to exclude interfering connections operating on the same radio frequency as the actual connection between a base station and a mobile station. According to the proposed method, the address (A1) to the intended receiver is added to the message (M) and an error check word (E) is calculated based on both the address (A1) and the message (M). Before transmitting to the receiver, the added address is removed and the transmitted control signal includes only the symbol message (M) and the error check code (E). In the receiver, the specific address for the receiver is added to the received control signal and the same calculation is carried out as in the transmitter in order to get an accept/reject signal.
