ABSTRACT:
A method of signal transmission between radio base stations (BSs) in a mobile communication system by using only one transmission system commonly used for both of communication with the exchange and communication with mobile stations (MSs) is realized. Each BS has at least one each of receiver and transmitter operable in the same frequency used in an adjacent BS, a call signal to be transferred is assigned in a channel slot of same radio signal as used for communication with MSs in own radio zone, the call signal contains destination indicator indicating an identification number of the BS to which the call signal is to be transferred, and each BS compares the indicator with own identification number, and if they coincide with each other, the call signal is extracted and used in the BS, but if they do not coincide with each other, the call signal is relayed to the next BS by transmitting radio signal containing the call signal in the same channel slot as received.
