상공을 이동 가능한 복수의 무선 중계 장치로 형성하는 복수의 셀의 셀 경계에 있어서의 핸드오버의 빈발에 의한 통신 품질의 열화를 억제하는 시스템 및 방법을 제공한다. 시스템은, 단말 장치와 무선 통신하는 복수의 무선 중계 장치는 각각, 상공을 비행하여 이동 가능하게 설치되고 지상 또는 해상을 향해 셀을 형성해 셀에 재권하는 단말 장치와 무선 통신하는 무선 중계국을 구비하고, 자율 제어에 의해 또는 외부로부터의 제어에 의해, 무선 중계 장치간`의 위치 관계를 유지하도록 서로 협조하여 비행한다.

    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.
