Abstract
It is suppressed of a deterioration of communication quality of a service link (SL) due to a local propagation-loss increasing part in a radio propagation path of a feeder link (FL) between an aerial-floating type communication relay apparatus and a gateway (GW) station. When the local propagation-loss increasing part occurs in the radio propagation path of the feeder link between the gateway station and the communication relay apparatus or when an occurrence of the propagation-loss increasing part is predicted, the communication relay apparatus is moved to a position capable of suppressing or avoiding the deterioration of communication quality due to the propagation-loss increasing part in the radio propagation path of the feeder link.
