Abstract: A communication system capable of realizing a three-dimensional network of the fifth generation mobile communication with low propagation delay in a radio communication is provided. The communication system comprises a radio relay station that relays a radio communication with the terminal apparatus. The radio relay station is provided in a floating object that is controlled so as to be located in a floating airspace with an altitude of 100 [km] or less by an autonomous control or an external control. When the floating object is located in the floating airspace, the radio relay station forms a three-dimensional cell in a predetermined cell-formation target airspace between the floating object and a ground level or a sea level.

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 apparatus 10 and each of terrestrial cellular base stations 20 and a communication relay apparatus 41 of artificial satellite 40. A radio resource used in the terrestrial cellular base stations 20 and a radio resource used in a satellite base station 30 in 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.

Abstract: When bandwidth is dynamically allocated for audio communication via satellite communication, newly occurring audio communication can negatively affect the communication quality of the existing audio communication. Provided is a data communication apparatus that communicates via a satellite and includes an allocation control section that allocates in advance, for audio communication via the satellite, a bandwidth that is larger than a bandwidth needed for current audio communication being performed via satellite by at least a predetermined bandwidth. A program causes a computer to function as this data communication apparatus. A satellite communication system includes this data communication apparatus and this satellite.
