Abstract: A mobile body communication system includes: a home base station that controls radio communication with a mobile unit; a macro cell base station that controls radio communication with one or more mobile units and radio communication with the home base station; and a quality control server QCS that is connected to the macro cell base station and manages communication quality between the macro cell base station and the home base station, wherein the quality control server QCS: additionally generates a session between the home base station and the macro cell base station when receiving a session generation request from the home base station; and releases the session between the home base station and the macro cell base station when receiving a session release request from the home base station. Communication quality in a radio network between the mobile unit(s) and the macro cell base station can be guaranteed.
