  • Patent number: 11659431
    Abstract: A receiver mounted on a vehicle moving on a route manages an operation profile that stores data in which a section that is a part of the route and a communication quality in the section are associated, and can receive a first traffic and a second traffic having a lower priority than the first traffic. The receiver determines a section having a good communication quality to a transmission section where the second traffic can be transmitted with reference to the operation profile, and generates control information for controlling transmission of the second traffic not to hinder transmission of the first traffic when the vehicle is located in the transmission section.
