Abstract
A mobile communication system and its multiple connection method enabling to perform concise and high quality multiplex communication, in which a mobile exchange station stores identifiers of a plurality of radio base stations and transmits a communication signal directed to a mobile station to all the radio base stations. The mobile exchange station stores the identifier of the radio base station which started the communication with the mobile station within the plurality of radio base stations. When the radio base station has opened a radio line with the mobile station, the radio base station which received the communication signal transmits the communication signal to a radio zone, and when the radio base station does not open the radio line with the mobile station, the radio base station disuses the received communication signal. When receiving a communication channel handover request, the radio base station which received the communication signal directed to the mobile station from the mobile exchange station executes a handover processing directly, and when not having received the communication signal, the radio base station requests the mobile exchange station to transmit the communication signal to carry out a multiple connection processing.
