To provide a radio relay system capable of starting relay of radiocommunication promptly between a fixed base station and user equipment in the mobile communication network of multiple communication operators, after moving to a target position, by simple configuration.SOLUTION: A mobile first radio repeater station transmits and receives multiple radio signals of first frequency between multiple fixed base stations, transmits and receives multiple radio signals of second frequency between a second radio repeater station, executes frequency conversion of first and second frequencies for each communication operator and adjusts signal power after frequency conversion so as to be equal to each other between multiple communication operators. The second radio repeater station transmits and receives multiple radio signals of second frequency between the first radio repeater station, transmits and receives multiple radio signals of first frequency between user equipment, executes frequency conversion of first and second frequencies for each communication operator and adjusts signal power after frequency conversion so as to be equal to each other between multiple communication operators.SELECTED DRAWING: Figure 1

    【課題】簡易な構成で、目標位置に移動した後、複数の通信オペレータの移動通信網について固定基地局とユーザ装置との間の無線通信の中継を速やかに開始することができる無線中継システムを提供する。【解決手段】移動可能な第1無線中継局は、複数の固定基地局との間で複数の第1周波数の無線信号を送受信し、第2無線中継局との間で複数の第2周波数の無線信号を送受信し、通信オペレータごとに第1周波数と第2周波数との周波数変換を行うとともに周波数変換後の信号電力を複数の通信オペレータ間で互いに等しくなるように調整する。第2無線中継局は、第1無線中継局との間で複数の第2周波数の無線信号を送受信し、ユーザ装置との間で複数の第1周波数の無線信号を送受信し、通信オペレータごとに第1周波数と第2周波数との周波数変換を行うとともに周波数変換後の信号電力を複数の通信オペレータ間で互いに等しくになるように調整する。【選択図】図1
