Abstract
Mobile communication systems and base station control apparatuses are provided, by which a spectral efficiency can be improved while preventing interference between a terrestrial cellular mobile communication system and a satellite mobile communication system, and mobile communication services using mobile station apparatuses can be provided more surely in an emergent condition in which a failure occurs in a part of terrestrial cellular base stations. A same frequency band is used for radio communications between a mobile station apparatusand each of terrestrial cellular base stationsand a communication relay apparatusof artificial satellite. A radio resource used in the terrestrial cellular base stationsand a radio resource used in a satellite base stationin a common area where the terrestrial cellular mobile communication system and the satellite mobile communication system are available are allocated so as not to overlap with each other, and the radio resource allocated for the satellite base station is increased in the emergent condition in which a failure occurs in a part of the terrestrial cellular base stations so as to be more than that in a normal condition.
