Abstract: An image reception unit receives an internal image from a mobile object. An accident risk prediction unit predicts a risk of occurrence of an accident inside the mobile object based on the internal image and situation information indicating a situation of the mobile object. A quality determination unit determines internal image quality information indicating quality of the internal image based on a result of the predicted risk of the inside accident. A quality adjustment unit adjusts the quality of the internal image based on the internal image quality 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 method and a radio parameter control system, as well as a network operation management apparatus and a radio station, are provided that enable optimization control for problems varying with sites of occurrence. Using location information at the time of measurement included in a measurement report from a radio terminal (30) located in a radio cell (C10), quality indicators based on measurement information acquired by the radio terminals or the radio station are compiled in association with areas (Ai), each of which is smaller than the radio cell (C10), and control of a radio parameter is performed in the radio cell or across a plurality of radio cells, based on a result of compilation of the quality indicators for each area.
