A mobile communication system has a base station and a plurality of mobile stations. When a mobile station detects a self station code, it transmits the self station code of the mobile station to the base station by using weak radio waves. The base station performs scanning, using its scanning antenna so as to change the directivity direction, catches the weak radio waves sent from the mobile station, and detects the mobile station code included in the reception signal. Thereby, a requester is told that the call of the mobile station has surely been made. By using the scanning antenna, a notification that the mobile station has surely received the call from the base station is reliably conveyed from the mobile station to the base station by using weak radio waves.
