Abstract

Provided is a wireless communication system including: one or more mobile wireless station devices that communicate with one or more terminal devices; and a control device, in which the control device calculates, on the basis of a position of each of the terminal devices, a plurality of movement destination position candidates of each of the mobile wireless station devices of which communication with the terminal device satisfies a required quality, and from among a plurality of the movement destination position candidates, selects, as a movement destination position for movement control, a movement destination position candidate having a minimum sum of movement costs for movement from a home position to a movement destination for the mobile wireless station device or a movement destination position candidate for which a maximum value of a movement cost for movement from the home position to the movement destination becomes minimum for one or more mobile wireless station devices.

First claim

1 . A radio communication system comprising:
one or more mobile wireless station devices configured to communicate with one or more terminal devices; and a control apparatus including circuitry configured to:
calculate, based on a position of each of the terminal devices, a plurality of candidate destination positions of each of the mobile wireless station devices where communication with the terminal devices satisfies a required quality, and
from among the plurality of the candidate destination positions, select, as a destination position for movement control, either:
(i) a first candidate destination position where a total sum of movement costs for the mobile wireless station devices to move from respective home positions to destinations is minimized, or
(ii) a second candidate destination position where a maximum value among movement costs for at least one of the one or more mobile wireless station devices to move from a home position to a destination is minimized.

2 . The radio communication system according to claim 1 , wherein the circuitry of the control apparatus is configured to calculate the candidate destination positions of each of the mobile wireless station devices by performing clustering of the terminal devices.

3 . A control apparatus in a radio communication system including (i) one or more mobile wireless station devices configured to communicate with one or more terminal devices, and (ii) the control apparatus, the control apparatus comprising:
circuitry configured to:
calculate, based on a position of each of the terminal devices, a plurality of candidate destination positions of each of the mobile wireless station devices where communication with the terminal devices satisfies a required quality; and
from among the plurality of the candidate destination positions, select, as a destination position for movement control, either:
(i) a first candidate destination position where a total sum of movement costs for the mobile wireless station devices to move from respective home positions to destinations is minimized, or
(ii) a second candidate destination position where a maximum value among movement costs for at least one of the one or more mobile wireless station devices to move a home position to a destination is minimized.

4 . The control apparatus according to claim 3 , wherein the circuitry is configured to calculate the candidate destination positions of each of the mobile wireless station devices by performing clustering of the terminal devices.

5 . A move destination position determination method executed by a control apparatus in a radio communication system including:
one or more mobile wireless station devices that communicate with one or more terminal devices, and a control apparatus, the method comprising: calculating, based on a position of each of the terminal devices, a plurality of candidate destination positions of each of the mobile wireless station devices where communication with the terminal devices satisfies a required quality; and from among the plurality of the candidate destination positions selecting, as a destination position for movement control, either:
(i) a first candidate destination position where a total sum of movement costs for the mobile wireless station devices from respective home positions to destinations is minimized, or
(ii) a second candidate destination position where a maximum value among movement costs for at least one of the one or more mobile wireless station devices is minimized

6 . A non-transitory computer readable storage medium storing a program for causing a computer to execute the move destination position determination method of claim 5 .
