APPARATUS AND METHOD FOR CONTROLLING SIGNAL QUALITY OF ANTENNA

The present invention relates to an apparatus and method for controlling signal quality of an antenna.

Conventionally, for network optimization of mobile communication base stations, signal quality was measured by moving a signal measuring device within the network using a vehicle.

Also, the clamping device 10 may rotate the antenna 1 by a predetermined angle in the left and right directions according to the received third and fourth adjustment signals.

On the other hand, when the signal quality measurement value Q1 calculated based on the first measurement data is transmitted again after the antenna 1 is rotated in the left and right directions, the rotation determining unit 150 determines the By comparing the signal quality target value QR and the signal quality measurement value Q1 , the rotation direction and angle of the antenna 1 may be determined according to the difference value QR-Q1 .

In this case, the rotation determining unit 150 determines the rotation direction and angle in the same manner as described above, but since the antenna 1 has been rotated in the left and right directions through the previous process, the rotation direction of the antenna 1 is adjusted up and down. direction can be determined.

Accordingly, the control unit 110 may sequentially transmit the first adjustment signal, the second adjustment signal, the third adjustment signal, and the fourth adjustment signal to the clamping device 10 in the vertical direction.

The clamping device 10 may rotate the antenna 1 by a predetermined angle in the vertical direction according to the received first adjustment signal, the second adjustment signal, the third adjustment signal, and the fourth adjustment signal.

Accordingly, when the signal quality of the antenna 1 measured by the vertical rotation of the antenna 1 satisfies the target value, the controller 110 may end the related operation.

On the other hand, if the signal quality of the antenna 1 measured by the vertical rotation of the antenna 1 does not satisfy the target value, the controller 110 sequentially measures the signal quality of the first terminal 21 to the fourth terminal 24 . You can also request data again.

Specifically, in relation to operations 411, 421, 431, and 441 illustrated in FIG. 7 , when the first terminal 21 to the fourth terminal 24 are spatially disposed at different positions, the first data to The fourth data may be sequentially or simultaneously transmitted to the signal quality control device 100 , and if the terminal device 20 is implemented in the form of a drone or mounted on a drone, the position of the terminal device 20 is According to the change, a plurality of quality measurement data (eg, first data to fourth data) may be sequentially transmitted to the communication unit 120 of the signal quality control apparatus 100 .

An operation flow of the apparatus for controlling signal quality of an antenna according to the present invention configured as described above will be described in more detail as follows.

8 and 9 are diagrams illustrating an operation flow of a method for controlling signal quality of an antenna according to an embodiment of the present invention.

Referring to FIG. 8 , the signal quality control apparatus 100 requests first data from the first terminal 21 among n terminal devices 20 disposed in the network ( S110 and S120 ).

When the first data is received from the first terminal 21 ( S130 ), the signal quality control apparatus 100 performs a signal quality target value (QR) based on the transmission signal of the antenna 1 and a first data-based signal quality measurement value ( Check whether the difference between Q1) becomes 0 (or within the error range). If the difference value is 0 (or within the error range) (S140), the signal quality control apparatus 100 requests the second data from the second terminal 22 of the next order (S170, S180, S120).

On the other hand, if the difference value is not 0 (or within the error range) in the process 'S140', the signal quality control apparatus 100 preferentially determines the rotation direction to the left-right direction, and determines the rotation angle for the left-right direction ( S150). Here, the signal quality control apparatus 100 may determine the rotation angle according to the difference value in the process 'S140', or may determine the rotation angle as a predetermined value.

The signal quality control apparatus 100 transmits the left/right adjustment signal including the rotation direction and rotation angle determined in the process 'S150' to the clamping device 10 (S160). Accordingly, the clamping device 10 may adjust the rotation of the antenna 1 according to the received left/right adjustment signal.

Thereafter, the signal quality control apparatus 100 transmits the n-th left-right adjustment signal including the rotation direction and rotation angle determined based on the n-th data received from the n-th terminal to the clamping device 10 until 'S120' to 'S180' is repeated.

Accordingly, the clamping device 10 adjusts the rotation of the antenna 1 in the left and right directions for n times. However, the case where the difference value of the process 'S140' is 0 (or within the error range) may be excluded.

After the signal quality control apparatus 100 transmits the n-th left-right adjustment signal to the clamping apparatus 10, the process after 'A' of FIG. 9 is performed.

Referring to FIG. 9 , the signal quality control apparatus 100 determines a difference between a signal quality target value (QR) based on a transmission signal of the antenna 1 and an n-th data-based signal quality measurement value (Qn) last measured in FIG. 8 . Check that the value is 0 (or within the margin of error). If the difference value is 0 (or within the error range) (S210), the signal quality control apparatus 100 may determine that the signal quality of the antenna 1 satisfies the target value and terminate the signal quality control operation. .

On the other hand, if the difference value is not 0 (or within the error range) in the process 'S210', the signal quality control apparatus 100 transmits the first The data is requested again (S220, S230).

Thereafter, when the first data is received from the first terminal 21 ( S240 ), the signal quality control apparatus 100 performs a signal quality target value (QR) based on the transmitted signal of the antenna 1 and the first data based signal quality Check whether the difference between the measured values Q1 is 0 (or within the error range). If the difference value is 0 (or within the error range) (S250), the signal quality control apparatus 100 requests the second data from the second terminal 22 of the next order (S290, S230).

On the other hand, if the difference value is not 0 (or within the error range) in the process 'S250', the signal quality control apparatus 100 determines the rotation direction in the vertical direction and determines the rotation angle with respect to the vertical direction (S260) . Here, the signal quality control apparatus 100 may determine the rotation angle according to the difference value in the process 'S250', or may determine the rotation angle as a predetermined value.

The signal quality control apparatus 100 transmits the vertical adjustment signal including the rotation direction and the rotation angle determined in the process 'S260' to the clamping device 10 (S270). Accordingly, the clamping device 10 may adjust the vertical rotation of the antenna 1 according to the received vertical adjustment signal.

Thereafter, the signal quality control apparatus 100 transmits the n-th vertical adjustment signal including the rotation direction and rotation angle determined based on the n-th data received from the n-th terminal to the clamping device 10 until 'S230' to 'S290' is repeated.

Accordingly, the clamping device 10 adjusts the vertical rotation of the antenna 1 for n times. However, the case where the difference value of the process 'S250' is 0 (or within the error range) may be excluded.

If the signal quality of the antenna 1 does not satisfy the target value even after the n-th left and right adjustment signal is transmitted to the clamping device 10, the signal quality control device 100 re-performs the operation from the process 'S110' of FIG. can As another example, if the signal quality does not satisfy the target value even after adjusting the left and right and vertical rotation of the antenna 1 , the signal quality control apparatus 100 may guide it and end the related operation.
