ABSTRACT:
A radio communication system having a plurality of mobile stations, at least one base station, and a control side apparatus connected to the base station. Each mobile station has a mode switching instruction reception unit for receiving an instruction for switching from a radio communication mode for performing a radio communication operation to a loudspeaker mode or a hot mic mode, a destination identifying information storage unit for storing information for identifying a communication apparatus which serves as a communication partner when the mode switching instruction reception unit receives the instruction for switching to the hot mic mode, and a destination identifying information transmission unit responsive to the received instruction for switching to the hot mic mode by the mode switching instruction reception unit for transmitting the information stored in the destination identifying information storage unit over the air.
