POWER CONTROL FOR FLYING BASE STATION

A communication control apparatus for a communication system with a ground station, which is at least partly installed on the ground and can communicate with a communication device, and a flying base station, which can communicate with the ground station, includes: an available power estimation unit to estimate available power of the flying base station; a required total power estimation unit to estimate total power required by the flying base station for communication with each communication device connected to the ground station; and a communication mode change unit to change communication mode between at least one communication device and the flying base station, at least when the total power is more than the available power, so that the total power becomes less than the available power.
