Abstract: A vehicle configured to so as to be able to be remotely driven transmits information about each vehicle to a vehicle control apparatus through a network. In the vehicle control apparatus, an analysis unit receives information about each vehicle. The analysis unit analyzes state information of each vehicle based on the received information about each vehicle. Each remote control unit performs at least one of remote monitoring or remote control for at least one of a plurality of vehicles. An assignment determination unit determines a correspondence relationship between the vehicle and the remote control unit based on the analyzed state information.

Abstract: [Problem] To estimate an open band in a wireless link precisely without imposing a communication load.[Solution] An open band in a wireless link is calculated from the bandwidth for a wireless link between a first wireless station and a second wireless station, a radio resource utilization rate, which is the ratio of the number of frequency blocks used for signal transmission with respect to the multiple frequency blocks constituting the bandwidth, and the radio quality of the wireless link.

Abstract: A radio communication system, a radio station, a network operation management apparatus, and a network optimization method are provided that make it possible to avoid performance degradation in the entire system when network optimization is performed individually. In the radio communication system in which radio stations perform network optimization based on statistical communication quality in at least one cell, a radio station (10) notifies information related to a change in statistical communication quality in a cell under the radio station (10) to another radio station (20) or a network apparatus (30) managing the another radio station.
