Abstract

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.

First claim

1 . A control system comprising:
a detection unit that detects a prescribed object in an image acquired by a camera; an extraction unit that extracts, from the image, object information relating to the detected object; a prediction unit that predicts, based on the object information, communication demand for a base station from a radio terminal that the detected object has; a determination unit that determines a setting of the base station based on the predicted communication demand; and a control unit that controls the base station in accordance with the determined setting.

2 . The control system according to claim 1 , wherein the object information includes at least one of; object attribute information relating to an attribute of the object, and object behavior information relating to a behavioral characteristic of the object.

3 . The control system according to claim 1 , further comprising
a monitoring unit that monitors communication information relating to communication between the radio terminal and a second base station having a coverage area at least partially overlapping with a coverage area of a first base station, which is the aforementioned base station, and using a carrier frequency lower than a carrier frequency of the first base station, wherein the determination unit determines the setting further based on the monitored communication information.

4 . The control system according to claim 3 , wherein the communication information includes at least one of traffic volume and data type.

5 . The control system according to claim 1 , wherein:
the first base station, which is the aforementioned base station, comprises an RU (Radio Unit), a DU (Distributed Unit), and a CU (Centralized Unit); the determination unit determines, as the setting, that the RU in the first base station is to be turned either on or off; and the control unit controls 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); the determination unit determines, as the setting, whether to delete or to instantiate the virtualized DU; and the control unit controls the first base station to be in an off-the-air state by deleting the virtualized DU, and controls 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); the determination unit determines, as the setting, whether to delete, to scale in, to scale out, or to instantiate the virtualized DU; and the control unit controls the first base station to be in an off-the-air state by deleting the virtualized DU, and controls the first base station to be in an on-the-air state by scaling in, scaling out, or instantiating the virtualized DU.

8 . The control system according to claim 2 , wherein:
the object is a person; the object attribute information includes at least one of an age of the person, a sex of the person, and a type of radio terminal that the person has; and the object behavior information includes at least one of a movement speed of the person, an amount of change in the movement speed of the person within a prescribed time period, a stationary time period of the person, and information relating to a carrying mode indicating how the person is carrying the radio terminal.

9 . The control system according to claim 2 , wherein:
the object is a vehicle; the object attribute information includes at least one of information indicating whether or not the vehicle has functions of an ICT (Information and Communication Technology) terminal, and a type of radio terminal that the vehicle has; and the object behavior information includes at least one of a movement speed of the vehicle, an amount of change in the movement speed of the vehicle within a prescribed time period, and a stationary time period of the vehicle.

10 . The control system according to claim 1 , wherein the image is an image of at least a part of a coverage area of a first base station, which is the aforementioned base station.

11 . A control method performed by one or more processors, the control method including:
detecting a prescribed object in an image acquired by a camera; extracting, from the image, object information relating to the detected object; predicting, based on the object information, communication demand for a base station from a radio terminal that the detected object has; determining a setting of the base station based on the predicted communication demand; and controlling the base station in accordance with the determined setting.
