Abstract
In a mobile communication system having two operating systems co-existing in one area, a mobile station having a transmitting and receiving circuit and a control unit for subscribing to one of the two mobile communication systems by selecting a control channel thereof is provided. Accordingly, a normal scan of the control channel of the subscribed-to system is activated, and then an extra scan of the control channel is activated when the control channel is not available during the normal scan. The possibility of an involuntary connection to a non-subscribed-to system is thereby reduced when the mobile station is temporarily in a blind section of the subscribed-to system.
