The invention relates to a call control method for a radio system, wherein a semi-duplex type mobile station (MS1, MS2) is commanded so as to clear a call on the radio channel of a base station (BS), by transmitting a disconnect signal to the mobile station (MS1, MS2) over said radio channel, the mobile station leaving the radio channel on receiving said disconnect signal. In order to ensure that the disconnect signal is received by the mobile station, the field intensity received by the base station (BS) on said radio channel is measured immediately after the transmission of the disconnect signal, and the radio channel is released for the next call only when the measured field intensity falls below a predetermined threshold value. |
