CONTROL DEVICE AND BASE-STATION CONTROL METHOD
A control device includes, a predictor that predicts group traffic of a group including a plurality of base-station devices, with use of respective amounts of individual traffic of the plurality of base-station devices, and a controller that determines whether to stop or operate a base-station device in the group, in accordance with the predicted group traffic, wherein the group includes a base-station device that forms a macro-cell and a base-station device that forms a small cell, and the small cell includes a region overlapping the macro-cell.
1 . A control device comprising:
a predictor that predicts group traffic of a group including a plurality of base-station devices, with use of respective amounts of individual traffic of the plurality of base-station devices; and
a controller that determines whether to stop or operate a base-station device in the group, in accordance with the predicted group traffic, wherein
the group includes a base-station device that forms a macro-cell and a base-station device that forms a small cell, and
the small cell includes a region overlapping the macro-cell.
2 . The control device according to claim 1 , wherein
an entire region of the small cell overlaps a region of the macro-cell.
3 . The control device according to claim 1 , wherein
a proportion of the region of the small cell overlapping the macro-cell to an entire region of the small cell is a first threshold or more.
4 . The control device according to claim 1 , wherein
the controller sums up the respective amounts of individual traffic of the plurality of base-station devices to calculate the group traffic.
5 . The control device according to claim 1 , wherein
the controller allocates the group traffic in accordance with areas of respective cells that the plurality of base-station devices form to calculate respective amounts of corrected individual traffic of the plurality of base-station devices.
6 . The control device according to claim 1 , wherein
the controller calculates, with use of the group traffic, respective amounts of individual traffic of the plurality of base-station devices, and
adds, as an addition, first individual traffic of a first base-station device that is a stopping target to second individual traffic of a second base-station device that is not a stopping target and determines whether to stop or operate a base-station device while taking the addition into account.
7 . The control device according to claim 1 , wherein
the group traffic is output from a learning model that has learnt respective amounts of measured traffic of the plurality of base-station devices and predicts the group traffic.
8 . The control device according to claim 1 , wherein
the controller controls the base-station device, which is a stopping target, to stop.
9 . A base-station control method comprising:
predicting group traffic of a group including a plurality of base-station devices, with use of respective amounts of individual traffic of the plurality of base-station devices; and
determining whether to stop or operate a base-station device from among the plurality of base-station devices in the group, in accordance with the group traffic, wherein
the group includes a base-station device that forms a macro-cell and a base-station device that forms a small cell, and
the small cell includes a region overlapping the macro-cell.
