Control system, control method, and control program
An objective is to provide a control system, a control method, and a control program that can appropriately set a base station forming a small cell. A detection unit ( 811 ) detects a prescribed object in an image acquired by a camera. An extraction unit ( 812 ) extracts, from the image, object information relating to the detected object. A prediction unit ( 813 ) predicts, based on the object information, communication demand for a base station from a radio terminal that the detected object has. A determination unit ( 820 ) determines a setting of the base station based on the predicted communication demand. A control unit ( 830 ) controls the base station in accordance with the determined setting.

the one or more processors are further configured to execute the computer program to:
determine, as the setting, that the RU in the first base station is to be turned either on or off, and
control the first base station to be in either an off-the-air state or an on-the-air state by controlling the RU in the first base station to be either on or off.
6. The control system according to claim 1 , wherein:
the first base station, which is the aforementioned base station, comprises an RU (Radio Unit), a virtualized DU (Distributed Unit), and a virtualized CU (Centralized Unit); and
the one or more processors are further configured to execute the computer program to:
determine, as the setting, whether to delete or to instantiate the virtualized DU, and
control the first base station to be in an off-the-air state by deleting the virtualized DU, and control the first base station to be in an on-the-air state by instantiating the virtualized DU.
7. The control system according to claim 1 , wherein:
the first base station, which is the aforementioned base station, comprises an RU (Radio Unit), a virtualized DU (Distributed Unit), and a virtualized CU (Centralized Unit); and
the one or more processors are further configured to execute the computer program to:
determine, as the setting, whether to delete, to scale in, to scale out, or to instantiate the virtualized DU, and
control the first base station to be in an off-the-air state by deleting the virtualized DU, and control the first base station to be in an on-the-air state by scaling in, scaling out, or instantiating the virtualized DU.
