Abstract

A base station control system includes a first base station of which a disposition position is not determined, and a base station control device including a memory and a processor configured to: divide an existing second base station and terminals connected to the second base station into clusters through clustering; determine a position corresponding to a cluster not including the second base station among the plurality of clusters as a disposition position of the first base station; calculate the number of first terminals connected to the first base station and the number of second terminals connected to the second base station for each of a plurality of transmission powers of the first base station in a case where the first base station is disposed at the position; and select a transmission power of the first base station based on the number of first terminals and the number of second terminals.

Claims (24)

1 . A base station control system comprising:

a first base station of which a disposition position is not determined; and

a base station control device

including a memory and a processor configured to:

divide an existing second base station and terminals connected to the second base station into clusters through clustering,

determine a position corresponding to a cluster not including the second base station among the plurality of clusters as a disposition position of the first base station,

calculate the number of first terminals connected to the first base station and the number of second terminals connected to the second base station for each of a plurality of transmission powers of the first base station in a case where the first base station is disposed at the position, and

select a transmission power of the first base station based on the number of first terminals and the number of second terminals.

2 . The base station control system according to claim 1 , wherein the second base station is any of the second base stations having a relatively large number of connected terminals among the plurality of existing base stations.

3 . The base station control system according to claim 1 , wherein the processor calculates the number of third terminals that are not connectable to either the first base station or the second base station for each of the plurality of transmission powers of the first base station, and

the processor selects the transmission power of the first base station based on the number of the first terminals, the number of the second terminals, and the number of the third terminals.

4 . The base station control system according claim 1 , wherein the processor further selects the transmission power of the first base station based on a received power of the first terminal from the first base station and a received power of the second terminal from the second base station that are specified for each transmission power in a case where one transmission power cannot be selected.

5 . A base station control method executed by a base station control device including a memory and a processor configured to control a first base station of which a disposition position is not determined, the method comprising:

dividing an existing second base station and terminals connected to the second base station into clusters through clustering;

determining a position corresponding to a cluster not including the second base station among the plurality of clusters as a disposition position of the first base station;

calculating the number of first terminals connected to the first base station and the number of second terminals connected to the second base station for each of a plurality of transmission powers of the first base station in a case where the first base station is disposed at the position; and

selecting a transmission power of the first base station based on the number of first terminals and the number of second terminals.

6 . A non-transitory computer-readable recording medium having computer-readable instructions stored thereon, which, when executed, cause a computer to execute the method according to claim 5 .

7 . A base station control device that controls a first base station of which a disposition position is not determined, the base station control device comprising:

a memory and a processor configured to:

divide an existing second base station and terminals connected to the second base station into clusters through clustering;

determine a position corresponding to a cluster not including the second base station among the plurality of clusters as a disposition position of the first base station;

select a transmission power of the first base station based on the number of first terminals and the number of second terminals.
