There is provided a communication control apparatus comprising a processor. The processor receives, from a first mobile communication apparatus, a request for permission of data transmission to a second mobile communication apparatus, the second mobile communication apparatus including a buffer memory to store received data. The processor determines whether to permit the data transmission based on a free capacity of the buffer memory and a reserved capacity indicated by a reservation setting of the buffer memory. The processor updates, when the data transmission is determined to be permitted, the reservation setting such that a capacity for received data corresponding to the data transmission is added to the reserved capacity. The processor transmits, when the data transmission is determined to be permitted, a response indicating that the data transmission is permitted to the first mobile communication apparatus.

Communication control apparatus, communication system, communication control method, and storage medium for determining whether to permit data transmission

A TCU includes: a wide-area communication section that performs wireless communication with a base station; a short-range communication section that performs wireless communication with an access point; a vehicle-to-vehicle communication section that performs wireless communication with a relay vehicle; and a communication control section that transmits upload data by using any one of the wide-area communication section, the short-range communication section, and the vehicle-to-vehicle communication section, wherein the communication control section transmits the upload data more preferentially by using the short-range communication section or the vehicle-to-vehicle communication section than by using the wide-area communication section when an upload deferment condition is met, and transmits the upload data more preferentially by using the wide-area communication section than by using the short-range communication section and the vehicle-to-vehicle communication section when the upload deferment condition is not met.

Communication device, communication method, non-transitory computer-readable storage medium storing communication program, and vehicle

A vehicle control apparatus includes a processor executing a communication control process of performing vehicle-to-vehicle communication, a data reception process of receiving and saving, in a storage unit, file data transmitted from a communication destination vehicle by the vehicle-to-vehicle communication, and an incompletely received file data management process of, in a case where the vehicle-to-vehicle communication is disconnected after reception of the file data by the data reception process is started and before the reception of the file data completes, setting, in accordance with a state of a predetermined parameter, at least one of an upper limit of a period for saving in the storage unit and a priority level for deleting from the storage unit for partial data of the file data saved in the storage unit.
