A mobile repeater for relaying radio signals between mobile stations and base station of a digital cellular radio network as the repeater moves from cell to cell. The mobile repeater includes a downlink branch for receiving from the base station and retransmitting to the mobile stations, an uplink branch for receiving from the mobile stations and retransmitting to the base stations, and an intelligent control unit for supporting the transition of the relay connection as the repeater moves from one cell to an adjacent cell. The intelligent control unit measures the repeater receiving field intensity of base station radio signals, monitors signalizing traffic, controls the signal output level to force transition to a new base station, and tunes the repeater frequency channels to those used by the new base station.
