1. A remote control apparatus for remotely controlling a communication relay apparatus having a feeder-link communication section that performs a feeder-link radio communication with each of a first gateway station and a second gateway station corresponding to each of a first cell and a second cell adjacent to each other, a service-link communication section that performs a radio communication with a terminal apparatus in each service link of the first cell and the second cell, and a control section that controls the service-link communication section so that a shape of the second cell is changed to include a whole of the first cell when a deterioration of a radio communication quality of the feeder link with the first gateway station corresponding to the first cell is predicted, the control section performing a control based on the control information received by the control-information receiving section, the remote control apparatus comprising:
an information acquisition section that acquires at least one of weather forecast information on an area including the propagation path of the feeder link with the first gateway station, maintenance schedule information of the first gateway station, monitoring information including a reception level of the feeder link with the first gateway station, flight path information on the communication relay apparatus, position information on the communication relay apparatus, and attitude information on the communication relay apparatus;
a control-information generating section that, in response to the deterioration of the radio communication quality of the feeder link between the communication relay apparatus and the first gateway station being predicted, generates control information for controlling the feeder-link communication section and the service-link communication section based on the information acquired by the information acquisition section; and
a control-information transmitting section that transmits the control information to the communication relay apparatus.
