An MEC node acquires, from each base station, a measured traffic volume in a cell (target cell) formed by each base station, and predicts a traffic volume after a unit time in the target cell based on the measured traffic volume. Upon receiving from a vehicle in the target cell an inquiry regarding whether or not data transmission is permitted, the MEC node determines whether or not to permit data transmission by the vehicle, based on a prediction result of the traffic volume, and a volume of data to be transmitted by the vehicle which is indicated by information included in the inquiry. In accordance with a result of the determination, the MEC node transmits, to the vehicle that has transmitted the inquiry, a response indicating whether or not to permit data transmission.

Node apparatus, method for controlling the same, and storage medium

A communication controller (communication control apparatus) acquires, from an MEC node (NW information collection unit), cell transition information for each vehicle that moves in a plurality of cells formed by a plurality of base stations connected to the MEC node. The communication controller determines a vehicle group that is made up of a plurality of vehicles and is to be subjected to uplink transmission control for path-dependent data based on the acquired cell transition information. The communication controller further performs, with respect to the determined vehicle group, transmission control for limiting uplink transmission of path-dependent data to a portion of vehicles that belong to the vehicle group.

Communication control apparatus, control method thereof, and storage medium

A merging support information (MSI) distribution apparatus includes a MSI reception unit configured to receive MSI including a speed recommended for a vehicle traveling on a branch line to merge with a main line from a merging prediction apparatus, a distribution destination information reception unit configured to receive distribution destination registration information including terminal movement information indicating a movement state of a mobile terminal mounted on the vehicle traveling on the branch line and terminal identification information identifying the mobile terminal from the mobile terminal via a mobile communication network, and an information distribution unit configured to specify the mobile terminal to be a distribution destination to which the MSI is distributed based on the branch line traveling information and the terminal movement information, and distribute the MSI to the specified mobile terminal via the mobile communication network based on the terminal identification information of the specified mobile terminal.
