The on-board relay station is configured to receive radio waves transmitted from a ground base station 60 to transmit the radio waves to a wireless terminal apparatus in the first wireless communication area, and to transmit radio waves transmitted from the wireless terminal apparatus in the first wireless communication area to the ground base station. The movable relay station is configured to relay radio waves transmitted/received between the on-board relay station and the ground base station.SELECTED DRAWING: Figure 3

    【課題】沿岸被災地などへ派遣される救援船(例えば、病院船)であって、被災地などの通信状況を改善しうる救援船を提供する。【解決手段】救援船1は、船体と、船体に搭載され、船体及び/又はその周囲に第1無線通信エリアを形成する船上中継局40と、船体に配備され船体から離れた任意の場所へ移動可能な少なくとも1つの移動体M(51)と、移動体に搭載された可動中継局70とを備える。船上中継局は、地上基地局60から送信された電波を受信して第1無線通信エリア内の無線端末機器へ送信し、第1無線通信エリア内の無線端末機器から送信された電波を地上基地局へ送信するように構成される。可動中継局は、船上中継局と地上基地局との間で送受信される電波を中継するように構成される。【選択図】図3
