Abstract
A relay communication station is remotely controlled without increasing communication traffic of a feeder link of communication to be relayed between a communication relay apparatus such as a HAPS located in an upper airspace and a communication network on the ground side or on the sea side. The communication relay apparatuses 10 and 20 comprise relay communication stations 110 and 210 that are respectively mounted on flying objects and relay communications between a terminal apparatus and a communication network via a feeder link for mobile communication, radio communication section 120 and 121 that transmit and receive control information to and from a remote control apparatus via a radio communication line for flight control different from the feeder link for mobile communication, and control sections (cell-optimization processing sections 122 and 123) that respectively control the relay communication stations based on the control information received from the remote control apparatus by the radio communication section.
