To provide a system and a method that prevent deterioration in communication quality due to frequent handovers at cell boundaries between a plurality of cells formed by a plurality of radio relay devices capable of moving over the sky.SOLUTION: A plurality of radio relay devices for wirelessly communicating with a terminal device each include a radio relay station that is movably provided by flying over the sky, forms a cell toward the ground or the sea, and wirelessly communicates with the terminal device situated in the cell. They fly in corporation with each other so as to maintain positional relation among the radio relay devices by autonomous control or control from the outside.SELECTED DRAWING: Figure 9

    【課題】上空を移動可能な複数の無線中継装置で形成する複数のセルのセル境界におけるハンドオーバの頻発による通信品質の劣化を抑制するシステム及び方法を提供する。【解決手段】端末装置と無線通信する複数の無線中継装置はそれぞれ、上空を飛行して移動可能に設けられ地上又は海上に向けてセルを形成してセルに在圏する端末装置と無線通信する無線中継局を備え、自律制御により又は外部からの制御により、無線中継装置間の位置関係を維持するように互いに協調して飛行する。【選択図】図9
