Description

Antenna downtilt evaluation method, device and computer-readable storage medium

technical field

The present application relates to the technical field of communications, and in particular to a method, device, and computer-readable storage medium for evaluating antenna downtilt angles.

Background technique

In the mobile communication network, the operator controls the coverage area of the antenna beam of the access network device by setting the downtilt angle of the antenna of the access network device. If the antenna downtilt of the access network device is set too small, the signal coverage of the access network device will be relatively large, so that the signal of the access network device will interfere with the signals of adjacent access network devices, and further This leads to problems of mutual interference and overlapping coverage between adjacent access network devices. If the downtilt angle of the antenna of the access network device is set too large, the signal coverage of the access network device will be small, which will lead to weak signals received by terminal devices at the edge of the preset coverage area, or even preset coverage. There are no issues with signal coverage (i.e., coverage holes) at the edges of the range. In order to avoid mutual interference, overlapping coverage, and coverage holes, it is necessary to evaluate the antenna downtilt angle of the access network equipment to determine whether the antenna downtilt angle setting is reasonable, so as to adjust the antenna downtilt angle in time when the antenna downtilt angle is unreasonable.

At present, manual evaluation is generally used to evaluate the antenna downtilt angle, that is, RF engineers conduct on-site surveys to see if the antenna downtilt angle is reasonable. However, manual on-site evaluation may cause deviations in the evaluation of antenna downtilt angle due to manual errors or insufficient manual accuracy, and manual evaluation requires RF engineers to go to the field to conduct surveys. The evaluation workload is heavy, time-consuming and labor-intensive.

In a communication network, adjacent access network devices usually use the same frequency point, that is, adjacent access network devices usually use the same frequency point for signal transmission, which will also cause adjacent access network devices to It is easy for devices to interfere with each other and overlap with each other. Therefore, a reasonable setting of the antenna downtilt angle is very important to ensure the normal coverage of the cell and reduce the signal interference between the cells. The setting of the antenna downtilt angle needs to be set according to the actual situation. The actual situation above includes: situation 1.1, the actual situation of the geographical environment of the site, and situation 1.2, the actual situation of user distribution.

In case 1.1, the transmission of electromagnetic signals will be affected to a certain extent due to topography, street direction, building distribution, blocking of high-rise buildings, diffraction of high-rise buildings, reflection of high-rise buildings, reflection of water surfaces, and absorption of trees. , therefore, the setting of the downtilt angle of the antenna needs to be set according to the actual situation of the geographical environment of the site.

In case 1.2, when the cells are in different areas, the distribution of terminal equipment in different area coverages will be different. Therefore, according to the different areas where the cells are located, it is also necessary to adaptively set the antenna downtilt angle. .

For example, in different regions, the distribution of user terminals also generally conforms to the tidal effect. The tidal effect refers to the phenomenon that a large number of people gather in office areas or industrial areas during working hours, and then migrate to residential areas after get off work.

One example, if an area is a residential area, the distribution of terminal devices in this area is less during the day, and the traffic volume is also small, while the distribution of terminal devices in this area is more, and the traffic volume is also larger at night.

Another example, if an area is an office area or an industrial area, the distribution of terminal equipment in this area is less at night, and the business volume is also small, while the distribution of terminal equipment in this area is more during the day, and the business volume is also small. more.

When adjusting the downtilt angle of the antenna in the prior art, it is usually necessary to evaluate the rationality of the downtilt angle of the antenna first, so as to avoid negative effects caused by blind adjustment. At present, manual evaluation is generally adopted, that is, the staff surveys whether the downtilt angle of the antenna is reasonable or not. However, manual on-site evaluation may cause deviations in the evaluation of the rationality of the antenna downtilt angle due to manual errors or insufficient manual accuracy, and manual evaluation requires staff to go to the field for surveying, which will also lead to a large workload, time-consuming and laborious The problem.

In order to solve the above-mentioned problems existing in the prior art, an embodiment of the present application proposes an antenna downtilt evaluation method, which can accurately and quickly evaluate the antenna downtilt angle. As shown in Figure 3, the method includes:

S301. The computing device determines a first coverage distance and a second coverage distance of a cell to be evaluated.

Wherein, the first coverage distance is the distance between the intersection point of the signal sent by the cell to be evaluated at the first preset angle and the ground, and the cell to be evaluated. The first preset angle is the difference between the downtilt angle of the antenna of the cell to be evaluated and the upper vertical half power angle.

The second coverage distance is the distance between the intersection point of the signal sent by the cell to be evaluated at the second preset angle and the ground, and the cell to be evaluated. The second preset angle is the sum of the downtilt angle of the antenna and the lower vertical half power angle.

Exemplarily, as shown in FIG. 4, the first coverage distance may be between point B1 (that is, the intersection point between the signal sent by the cell to be evaluated at the first preset angle and the ground) and point O (that is, the point where the cell to be evaluated is located) distance between. The second coverage distance may be the distance between point B2 (that is, the intersection point between the signal sent by the cell to be evaluated at the second preset angle and the ground) and point O.

In a possible implementation, the specific implementation process of the above S301 can be as follows: the computing device can determine the location of the cell to be evaluated, the antenna hanging height, the antenna downtilt angle, the upper vertical half power angle, and the lower vertical half power angle according to the industrial parameter data. The first coverage distance and the second coverage distance are respectively determined according to the position of the cell to be evaluated, the antenna hanging height, the antenna downtilt angle, the upper vertical half power angle, and the lower vertical half power angle.

S302. The computing device determines at least one third distance.

Wherein, any one of the at least one third distance is the distance between any one of at least one neighboring cell of the cell to be evaluated and the cell to be evaluated.

Exemplarily, as shown in FIG. 4, at least one neighboring cell includes three neighboring cells (ie, neighboring cell N1, neighboring cell N2, and neighboring cell N3). The 3rd distance of neighborhood N1 can be the distance between N1 point (being the location of neighborhood N1) and O point; The 3rd distance of neighborhood N2 can be N2 point (being the location of neighborhood N2) and O The distance between the points; the third distance of the neighbor N3 may be the distance between the point N3 (that is, the point where the neighbor N3 is located) and the point O.

In a possible implementation, the specific implementation process of the above S302 may be as follows: the computing device determines the location information of multiple neighboring cells of the cell to be evaluated, and selects the preset part of the neighborhood. The computing device determines the distance between the adjacent cell and the cell to be evaluated according to the location information of the adjacent cell and the cell to be evaluated, and selects at least one of the above-mentioned adjacent cells within the preset range according to the distance between the adjacent cell and the cell to be evaluated. Neighborhood.

S303. The computing device determines whether the antenna downtilt angle of the cell to be evaluated is reasonable according to at least one of the comparison results of the first coverage distance and at least one third distance, and the comparison results of the second coverage distance and at least one third distance.

In a possible implementation manner, the specific implementation process of the above S303 may be: the calculation device compares the first coverage distance with the third distance corresponding to at least one neighboring cell, and the second coverage distance and the at least one neighboring cell. At least one item in the comparison results of the third distance screens out the first adjacent area from the above-mentioned at least one adjacent area, and determines the number of adjacent areas of the first adjacent area and the number of adjacent areas of the above-mentioned at least one adjacent area, according to the first The ratio of the number of neighboring cells of a neighboring cell to the number of neighboring cells of at least one neighboring cell determines the antenna downtilt evaluation coefficient, and then the calculation device can determine the cell to be evaluated by comparing the relationship between the antenna downtilt evaluation coefficient and the preset threshold Whether the downtilt angle of the antenna is reasonable.

When the antenna downtilt evaluation coefficient is greater than a preset threshold, the computing device may determine that the antenna downtilt setting of the cell to be evaluated is unreasonable; The antenna downtilt of the evaluation cell is set reasonably.

The present application provides a method for evaluating antenna downtilt angle. The computing device determines the first coverage distance, the second coverage distance, and at least one third distance of the cell to be evaluated, and according to the comparison result of the first coverage distance and at least one third distance , and at least one of the comparison results of the second coverage distance and at least one third distance, it can be determined whether the coverage of the cell to be evaluated is within a reasonable range for each of the at least one neighboring cell. In this way, the computing device can determine the first coverage distance and the second coverage distance according to the antenna downtilt angle obtained from the industrial parameter data, the upper/lower vertical half-power angle, and the location information of the cell to be evaluated, and obtain The location information of at least one neighboring cell determines the third distance of at least one neighboring cell, and by comparing the first coverage distance with the third distance, or the second coverage distance with the third distance, it is possible to accurately and quickly determine whether the antenna preset angle is set Unreasonable evaluation avoids problems caused by manual survey.

In a possible implementation manner, referring to FIG. 3 , as shown in FIG. 5 , the above S303 may be specifically implemented through the following S501 to S505.

S501. The computing device determines a first neighboring cell from at least one neighboring cell.

Wherein, the comparison result of the first coverage distance and the third distance corresponding to the first neighboring cell satisfies the first preset condition. A comparison result between the second coverage distance and the third distance corresponding to the first neighboring cell satisfies the second preset condition. That is to say, the antenna downtilt setting of the cell to be evaluated relative to the first neighboring cell is unreasonable.

In a possible implementation manner, the first preset condition includes: the sum of the third distance corresponding to the first neighboring cell and the distance margin value is less than or equal to the first coverage distance. The second preset condition includes: the sum of the third distance corresponding to 0.5 times the first neighboring cell and the distance margin value is greater than or equal to the second coverage distance.

It should be pointed out that, in the case where the sum of the third distance corresponding to the first neighboring cell and the distance margin value is less than or equal to the first coverage distance, the computing device may determine that the antenna beam of the cell to be evaluated has covered the adjacent cell, The antenna beam coverage of the cell to be evaluated is too large. Therefore, in this case, the computing device may determine that for the neighboring cell, the setting of the antenna downtilt angle of the cell to be evaluated is unreasonable, and then determine that the neighboring cell is the first neighboring cell.

In the case where the sum of the third distance and the distance margin value corresponding to the first neighboring cell is greater than the second coverage distance at 0.5 times, the computing device may determine that the coverage distance of the cell to be evaluated does not reach half of the third distance of the neighboring cell, There may be a problem that the antenna beams of the cell to be evaluated cannot normally cover the edge area of the cell to be evaluated. Therefore, in this case, the computing device may determine that the setting of the antenna downtilt angle of the cell to be evaluated is unreasonable, and further determine that the neighboring cell is the first neighboring cell.

If the sum of 0.5 times ON1 and the distance margin value (7.7 meters) is greater than OB2 (6 meters), the computing device can determine that the comparison result between the second coverage distance and the third distance corresponding to the neighboring cell N1 satisfies the second preset condition. Therefore, in this case, the computing device may determine that the neighbor N1 is the first neighbor.

The sum of ON2 and the distance margin value (20.2 meters) is greater than OB1 (16 meters), and the computing device can determine that the comparison result between the first coverage distance and the third distance corresponding to the neighboring cell N2 does not meet the first preset condition. If the sum of 0.5 times ON2 and the distance margin value (10.2 meters) is greater than OB2 (6 meters), the computing device can determine that the comparison result between the second coverage distance and the third distance corresponding to the neighboring cell N2 satisfies the second preset condition. Therefore, in this case, the computing device can furthermore determine that the neighbor N2 is the first neighbor.

The sum of ON3 and the distance margin value (22.2 meters) is greater than OB1 (16 meters), and the computing device can determine that the comparison result between the first coverage distance and the third distance corresponding to the neighboring cell N3 does not satisfy the first preset condition. If the sum of 0.5 times ON3 and the distance margin value (11.2 meters) is greater than OB2 (6 meters), the computing device can determine that the comparison result between the second coverage distance and the third distance corresponding to the neighboring cell N3 satisfies the second preset condition. Therefore, in this case, the computing device can furthermore determine that the neighbor N3 is the first neighbor.

It should be noted that the distance margin value may be set by the computing device according to actual conditions. For example, the computing device sets the distance margin value to 0.5 meters.

Wherein, the antenna downtilt evaluation coefficient is a ratio of the number of neighboring cells of the first neighboring cell to the number of neighboring cells of at least one neighboring cell.

In a possible implementation, the specific implementation process of the above S502 may be as follows: the computing device may know the first neighboring cell through the above S501, and determine the number of neighboring cells of the first neighboring cell and the number of neighboring cells of the at least one neighboring cell. The number of zones, the antenna downtilt evaluation coefficient of the cell to be evaluated is determined according to the ratio of the number of neighbor cells of the first neighbor cell to the number of neighbor cells of at least one neighbor cell.

In conjunction with the example in FIG. 4, it can be seen that at least one of the three neighboring cells (i.e., neighboring cell N1, neighboring cell N2, and neighboring cell N3) in at least one neighboring cell satisfies the preset condition, and the computing device can determine that the neighboring cell N1, the neighboring cell N2, and the neighboring cell N3 are all the first neighboring cells, and then determine that the number of neighboring cells of the first neighboring cell is 3; the number of neighboring cells of at least one neighboring cell is 3. In this case, the computing device may determine that the antenna downtilt evaluation coefficient of the cell to be evaluated is 100%.

S503. The computing device determines that the antenna downtilt evaluation coefficient is greater than a preset threshold.

It should be noted that the computing device may set a preset threshold according to actual conditions. For example, the computing device sets the preset threshold to 50%.

If yes, the computing device executes S504.

S504. The computing device determines that the antenna downtilt setting of the cell to be evaluated is unreasonable.

Exemplarily, if the preset threshold is set to 50%, and the antenna downtilt evaluation coefficient of the cell to be evaluated is 100%, the computing device determines that the antenna downtilt setting of the cell to be evaluated is unreasonable.

If not, the computing device executes S505.

S505. The computing device determines that the antenna downtilt angle setting of the cell to be evaluated is reasonable.

Exemplarily, if the preset threshold is set to 50%, and the antenna downtilt evaluation coefficient of the cell to be evaluated is 30%, the computing device determines that the antenna downtilt of the cell to be evaluated is set reasonably.

The present application provides a method for evaluating antenna downtilt angles. The computing device determines the first coverage distance, the second coverage distance, and at least one third distance of the cell to be evaluated. By judging the first coverage distance, the second coverage distance, and The length relationship between the at least one third distance can determine whether the coverage of the cell to be evaluated is within a reasonable range for each neighboring cell in the at least one neighboring cell. If the above-mentioned length relationship between the first coverage distance, the second coverage distance, and the third distance satisfies the preset condition, the computing device can determine that the coverage of the cell to be evaluated is reasonable for the neighboring cell corresponding to the third distance ; If the above-mentioned length relationship between the first coverage distance, the second coverage distance, and the third distance satisfies an unpreset condition, the computing device may determine the coverage of the cell to be evaluated for the neighboring cell corresponding to the third distance If the range is not reasonable, then determine that the neighboring cell corresponding to the third distance is the first neighboring cell. And, by comparing the length relationship between the first coverage distance, the second coverage distance, and the third distance of each neighbor cell in the at least one neighbor cell, the computing device can determine the number of the first neighbor cell in the at least one cell. number, and then determine the ratio of the number of the first adjacent cell to the number of at least one adjacent cell as the coefficient to be evaluated for the antenna downtilt angle, and by comparing the relationship between the coefficient to be evaluated for the antenna downtilt angle and the preset threshold value, it can be determined Whether the downtilt angle of the antenna in the cell to be evaluated is reasonable. In this way, the computing device can accurately and quickly evaluate whether the downtilt angle of the antenna is set unreasonably, avoiding problems caused by manual survey.

Figure 3 and Figure 5 above describe the process of the computing device evaluating whether the antenna downtilt angle of the cell to be evaluated is reasonable.

In the process of the computing device evaluating whether the antenna downtilt of the cell to be evaluated is reasonable, the computing device needs to determine the first coverage distance and the second coverage distance (that is, the above S301). Referring to FIG. 3 , as shown in FIG. 6 , the specific process of S301 above can be implemented through the following S601 to S602 .

S601. The computing device determines the antenna height, antenna downtilt, and vertical half power angle of the cell to be evaluated.

It should be noted that the vertical half power angle includes an upper vertical half power angle and a lower vertical half power angle. Wherein, the upper vertical half power angle is equal to 0.5 times the vertical half power angle; the lower vertical half power angle is equal to 0.5 times the vertical half power angle.

It should be pointed out that the vertical half power angle can be set by the computing device according to actual conditions. For example, the computing device sets the vertical half power angle to 7°. Correspondingly, the upper vertical half power angle is 3.5°; the lower vertical half power angle is 3.5°.

Exemplarily, as shown in Figure 4, the lower vertical half power angle can be θ3 in Figure 4; the upper vertical half power angle can be θ2 in Figure 4; the vertical half power angle can be θ6 in Figure 4; That is, the lower vertical half power angle θ3=the upper vertical half power angle θ2=0.5×the vertical half power angle θ6. The downtilt angle of the antenna may be θ1 in FIG. 4 .

The computing device may determine the first preset angle θ4 according to the antenna downtilt angle θ1 and the upper vertical half power angle θ2 (ie θ4=θ1−θ2). The computing device may also determine the second preset angle θ5 according to the antenna downtilt angle θ1 and the lower vertical half power angle θ3 (ie θ5=θ1+θ3).

It should be noted that the above-mentioned antenna hanging height, antenna downtilt angle, and vertical half power angle can all be obtained from the industrial parameter data.

S602. The computing device determines a first coverage distance and a second coverage distance according to the antenna hanging height, the antenna downtilt angle, and the vertical half power angle.

In a possible implementation manner, the first coverage distance satisfies the following formula 1:

OBu ＝OA/tan(θ-0.5×φ) Formula 1

Among them, OBu is the first coverage distance; OA is the height of the antenna; θ is the downtilt angle of the antenna; φ is the vertical half power angle.

The second coverage distance satisfies the following formula 2:

OBd＝OA/tan(θ+0.5×φ) Formula 2

Wherein, OBd is the second coverage distance.

This application provides an antenna downtilt evaluation method. The computing device can respectively determine the first coverage distance and the second coverage distance through the antenna hanging height, antenna downtilt angle, and vertical half power angle, so as to determine the first coverage distance, the second coverage distance Whether the length relationship between the second coverage distance and at least one third distance satisfies a preset condition provides data preparation.

The above FIG. 6 records the process of determining the first coverage distance and the second coverage distance by the computing device.

Before the computing device determines at least one third distance, the computing device also needs to determine at least one neighboring cell of the cell to be evaluated, so as to provide data preparation for determining at least one third distance in S302 above. As shown in FIG. 7 , the process for the computing device to determine at least one neighboring cell of the cell to be evaluated can be implemented through the following steps S701-S704.

S701. The computing device determines a neighboring cell search angle and a neighboring cell search radius of a cell to be evaluated.

Wherein, the neighboring cell search angle is determined according to the number of sectors of the cell to be evaluated. The neighborhood search radius is an average value of multiple fourth distances. The fourth distance is the distance between any one of the multiple neighboring cells of the cell to be evaluated and the cell to be evaluated.

In a possible implementation, the neighboring cell search angle may satisfy the following formula 3:

M＝360/N+ext_angle Formula 3

Among them, M is the adjacent cell search angle; N is the number of sectors; ext_angle is the extension angle threshold.

It should be noted that the extended angle threshold (ie, ext_angle) may be set by the computing device according to actual conditions. For example, the computing device sets the expansion angle threshold to 20.

As an example, if the number of sectors is 6 and the extension angle threshold is set to 20, the computing device may determine that the neighboring cell search angle is 80° (that is, 360/6+20=80).

Another example, if the number of sectors is 3 and the extension angle threshold is set to 20, the computing device may determine that the neighboring cell search angle is 140° (ie 360/3+20=140).

It should be pointed out that the above multiple neighboring cells may be all neighboring cells of the cell to be evaluated; they may also be some neighboring cells of the cell to be evaluated. The number of the above-mentioned multiple neighboring cells can be set by the computing device according to the actual situation, which is not limited in this application.

S702. The computing device determines a preset neighbor cell search range according to the neighbor cell search angle and the neighbor cell search radius.

Exemplarily, as shown in FIG. 8 , the adjacent cell search angle is P in FIG. 8 , and the adjacent cell search radius is R in FIG. 8 . In this case, the computing device may determine that the sector area S1 composed of the neighboring cell search angle P and the neighboring cell search radius R in FIG. 8 is the preset neighboring cell search range of this application.

S703. The computing device determines a neighboring cell within a preset neighboring cell search range among the multiple neighboring cells as a second neighboring cell.

Exemplarily, as shown in FIG. 8, the computing device may determine that the neighboring cell N4, the neighboring cell N5, and the neighboring cell N6 within the preset neighbor cell search range (ie, the preset neighbor cell search range S1 in FIG. 8) are second neighborhood.

S704. The computing device determines at least one neighboring cell from the second neighboring cell.

Wherein, in the case where the quantity of the second neighboring region is less than or equal to L, the second neighboring region is at least one neighboring region; when the quantity of the second neighboring region is greater than L, the fourth smallest distance among the second neighboring regions The first L neighbors are at least one neighbor; wherein, L is a positive integer.

As an example, in the case where L is 3, if the number of neighboring cells (that is, the second neighboring cell) within the preset neighboring cell search range is 2, the computing device may determine two neighboring cells within the preset neighboring cell search range. The neighboring cells (ie, the second neighboring cell) are at least one neighboring cell.

Another example, in the case where L is 3, if the number of neighbors (that is, the second neighbors) within the preset neighbor search range is 5, the computing device may need to combine the 5 neighbors according to the fourth distance The districts are sorted from small to large, and then the first three neighboring districts with the fourth smallest distance are determined as at least one neighboring district.

The present application provides a method for evaluating antenna downtilt. The calculation device determines the preset neighbor search range through the neighbor search angle and the neighbor search radius of the cell to be evaluated, and determines that the neighbor within the preset neighbor search range is the second Neighboring cells, if the number of the second neighboring cells is within the preset range, the computing device determines that the second neighboring cell is at least one neighboring cell; if the number of the second neighboring cells is not within the preset range, the computing device determines the second neighboring cell Among the neighboring cells, the first L neighboring cells with the fourth smallest distance are determined to be at least one neighboring cell. In this way, the computing device can determine at least one neighboring cell of the cell to be evaluated, and provide data preparation for subsequent determination of at least one third distance.

It should be noted that the antenna downtilt evaluation method provided in the embodiment of the present application may be applicable to area/line coverage scenarios such as urban areas, county towns, and rural areas.

It should be pointed out that the aforementioned cell to be evaluated and multiple neighboring cells of the cell to be evaluated may be outdoor cells (the outdoor cells do not include high-speed rail cells).
