ABSTRACT:
A communication system includes a control unit, a switch and a diversity hand-over processing unit connected to the control unit and the switch for receiving, both a first communication signal received from a radio base station which outputs the hand-over instruction, and a second communication signal which receives it from another radio base station to which the communication signal will be hand-over to output one of the first and second communication signals to the associated interface circuit, and for transmitting the communication signal received through the radio base station from the mobile station on the reception side for communication to both the interface circuit associated with the radio base station as a source of hand-over and the interface circuit associated with the radio base station as a destination of hand-over. Thus, during the hand-over, the diversity hand-over processing unit transmits the communication signal from the mobile station on the reception side for communication to both the radio base station as a source of hand-over and the radio base station as a destination of hand-over so that the communication is established between the mobile station on the transmission side for communication and the mobile station as a destination of hand-over and on the reception side for communication.
