Abstract: In a digital twin system including a vehicle and a server that generates a digital twin of the vehicle, a reduction in volume of communication traffic between the vehicle and the server is achieved without a decrease in accuracy of the digital twin. A vehicle (101) includes: a plurality of sensors (S); an acquisition section (11) that acquires detection data from the respective plurality of sensors; and a communication section (2) that transmits at least some of the acquired detection data to a server (102) which predicts a future state of the vehicle by input of the detection data, and that receives, from the server, a behavioral indication based on prediction, after transmitting the detection data, the communication section transmitting subsequent detection data on the basis of a determination result indicating whether it is possible to transmit the subsequent detection data.

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.
