Abstract

Claims (39)

1 . A control apparatus for controlling a position and a direction of a base station and a position of a specific terminal that wirelessly communicates with the base station in conjunction with each other, the control apparatus comprising:

a processor; and

a memory that includes instructions, which when executed, cause the processor to execute:

acquiring information obtained by detecting a shield;

calculating a position candidate of the specific terminal based on information obtained by detecting the shield;

determining whether there is line-of-sight of the specific terminal from the base station for each of the position candidates of the specific terminal;

determining a position of the specific terminal based on a result of determination of presence or absence of the line-of-sight;

setting a range of values in advance for a first parameter indicating a position of the base station and for a second parameter indicating a direction of the base station; and

selecting one of a plurality of combinations of the values for the first parameter and the second parameter within the range, as a parameter indicating the position and the direction of the base station.

2 . The control apparatus according to claim 1 , wherein

the specific terminal is a monitoring camera, and

the processor is further caused to execute:

calculating a size of a monitoring area of the monitoring camera; and

determining the position of the specific terminal to maximize the calculated size of the monitoring area.

3 . The control apparatus according to claim 1 , wherein the processor is further caused to execute:

calculating a cover area quality of the base station; and

selecting the parameter indicating the position and the direction of the base station to maximize the calculated cover area quality.

4 . The control apparatus according to claim 1 , wherein the determining of the line-of-sight includes calculating a Fresnel zone from the base station, and determining that there is line-of-sight for a point in which a predetermined ratio of regions is not blocked among the calculated Fresnel zones.

5 . The control apparatus according to claim 1 , wherein the processor is further caused to execute:

acquiring terminal position information indicating a position of the specific terminal,

wherein the determining of the line-of-sight includes determining whether there is a line-of-sight in the specific terminal from the base station based on the terminal position information.

6 . The control apparatus according to claim 1 , wherein the processor is further caused to execute controlling a movement of the base station based on the calculated parameter indicating the position and the direction of the base station.

7 . A non-transitory computer-readable recording medium having computer-readable instructions stored thereon, which when executed, cause a computer including a memory and a processor to execute the acquiring, the calculating, the determining, the setting, and the selecting of the control apparatus according to claim 1 .

8 . A control method executed by a computer in a control apparatus for controlling a position and a direction of a base station, and a position of a specific terminal that wirelessly communicates with the base station in conjunction with each other, the control method comprising:

acquiring information obtained by detecting a shield;

calculating a position candidate of the specific terminal based on information obtained by detecting the shield;

determining whether there is line-of-sight of the specific terminal from the base station for each of the position candidates of the specific terminal;

determining a position of the specific terminal based on a result of determination of presence or absence of the line-of-sight;

setting a range of values in advance for a first parameter indicating a position of the base station and for a second parameter indicating a direction of the base station; and

selecting one of a plurality of combinations of the values for the first parameter and the second parameter within the range, as a parameter indicating the position and the direction of the base station.

9 . A control apparatus for controlling a position and a direction of a base station and a position of a specific terminal that wirelessly communicates with the base station in conjunction with each other, the control apparatus comprising:

a processor; and

a memory that includes instructions, which when executed, cause the processor to execute:

acquiring information obtained by detecting a shield;

calculating a position candidate of the specific terminal based on information obtained by detecting the shield;

determining whether there is line-of-sight of the specific terminal from the base station for each of the position candidates of the specific terminal; and

determining a position of the specific terminal based on a result of determination of presence or absence of the line-of-sight, and calculating a parameter indicating a position and a direction of the base station, wherein

the specific terminal is a monitoring camera, and

the calculating of the parameter includes calculating a size of a monitoring area of the monitoring camera, and determining the position of the specific terminal to maximize the calculated size of the monitoring area.
