A system and a method for suppressing a deterioration of communication quality due to frequent occurrence of handovers at cell boundaries of a plurality of cells formed by a plurality of radio relay apparatuses that can move in an upper airspace, are provided. In the system, each of the plurality of radio relay apparatuses for performing a radio communication with a terminal apparatus comprises a radio relay station which is movably provided by flying in an upper airspace, forms a cell toward the ground or the sea, and performs a radio communication with a terminal apparatus located in the cell. Each of the plurality of radio relay apparatuses flies in cooperation with each other so as to maintain a positional relationship between the radio relay apparatuses by an autonomous control or external control.
