Description
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for adjusting antenna coverage.
Background
With the development of LTE (Long Term Evolution), users of LTE are greatly increased, and how to meet accurate coverage of users becomes a difficult problem.
At present, coverage of a cell to users is mainly realized by adjusting an azimuth angle, a downtilt angle and a lobe width, wherein the azimuth angle represents the coverage characteristic of the cell in the horizontal direction, the downtilt angle represents the coverage characteristic in the vertical direction, and the lobe width represents the coverage range. The lobe width is mainly realized by configuring different amplitudes and phases, so for a certain cell, the more accurate the azimuth angle, the downtilt angle and the lobe width are identified, the more accurate the coverage is, and the better the coverage effect is.
When the coverage of the existing network is adjusted, field test is usually adopted, and then adjustment is carried out, so that the antennas with different problem sources are repeatedly adjusted, and a large amount of resources are consumed. How to realize one-time adjustment according to the actual conditions of users is effective for a long time, and the release of adjustment manpower becomes very important.
There are two main schemes for adjusting coverage and determining azimuth angle. One method is to confirm the azimuth Angle based on TA (Timing Advance) -AOA (Angle of Arrival direction), the method has the problem of large error of the determined azimuth Angle under various wireless environment conditions such as refraction, scattering, interference and the like, and the method does not consider the influence of a large number of reported sampling points of a single user and a small number of sampling points of multiple users on the azimuth Angle, and can not correctly judge whether the influence of the number of users on the azimuth Angle is large or whether the influence of the number of sampling points on the azimuth Angle is large, and can not accurately confirm the azimuth Angle when the reported sampling points of different users are not uniform.
The other method is a ray evaluation method, the characteristics of users and the distribution of the users are not fully considered in the method, so that the determined azimuth angle is not accurate, and the actual distribution conditions of the users and sampling points thereof are not fully considered in the method.
In addition, the lobe width and the downtilt angle of the cell cannot be determined by the above methods, which also affects the accuracy of the adjustment of the antenna coverage.
In summary, the problem of low accuracy in adjusting the antenna coverage in the prior art exists.

selecting the sampling information weight which is greater than the weight threshold value and is the smallest from the sampling information weights corresponding to all the coverage areas;
and taking the angle corresponding to the selected sampling information weight as the lobe width of the cell.
The method comprises the steps of sequentially selecting an angle from a set angle set; after selecting an angle, determining an initial coverage range according to a set angle and an initial direction, and rotating the coverage range according to a set movement angle by taking the center of a cell as the center of a circle until a new coverage range is overlapped with the initial coverage range; after the initial coverage range is determined and the coverage range is rotated once, the sampling information weight corresponding to the coverage range is determined according to the following modes: determining the number of terminals in a coverage area according to the sampling position of at least one terminal in the cell, and determining the sampling times in the coverage area according to the sampling position of at least one terminal in the cell and the sampling times on the sampling position; determining the sampling information weight corresponding to the coverage area according to the number and the sampling times of the terminals in the coverage area and the number and the sampling times of the terminals in the cell; selecting the sampling information weight which is greater than the weight threshold value and is the smallest from the sampling information weights corresponding to all the coverage areas; and taking the angle corresponding to the selected sampling information weight as the lobe width of the cell.

The details will be described below by way of example.
As shown in fig. 2, first, for a cell, all sampling points are displayed around the cell according to the longitude and latitude of all determined sampling positions and the sampling frequency of each sampling point;
setting an angle set of {10 degrees, 20 degrees, 30 degrees, 40 degrees, 8230, 10 degrees } and sequentially selecting an angle from the set angle set; for example 30 °;
then, when the true north direction is taken as the initial position and the center of the cell is taken as the center of a circle, determining an initial coverage range according to 30 degrees and the initial direction, and rotating the coverage range by taking the center of the cell as the center of a circle according to a set movement angle of 15 degrees until a new coverage range is overlapped with the initial coverage range; thus, the operation that the coverage area rotates for one circle when the included angle is 30 degrees is completed;
in the process, after an initial range is determined according to the selected angle and the determined initial position, the total number of users in the coverage range is calculated according to the sampling position of at least one terminal in the coverage range in the cell, and the total sampling times is calculated according to the sampling position in the coverage range in the cell; then, according to the number and the sampling times of the terminals in the coverage area and the number and the sampling times of the terminals in the cell, determining the sampling information weight corresponding to the coverage area;
then, rotating the coverage area by taking the center of the cell as the circle center according to a set moving angle to determine a new coverage area, immediately calculating the total number of users in the coverage area according to the sampling position of at least one terminal in the coverage area in the cell, and calculating the total sampling times according to the sampling position of the coverage area in the cell; then, according to the number and the sampling times of the terminals in the coverage area and the number and the sampling times of the terminals in the cell, determining the sampling information weight corresponding to the coverage area;
if the movement is repeated for the second time, the coverage range of rotating the coverage range by taking the center of the cell as the center of a circle according to the set movement angle is overlapped with the initial coverage range; i.e. the weight of the sampling information corresponding to the included angle of 30 degrees is accepted to be calculated;
and selecting an angle from the set angle set again to serve as an included angle, performing the operation, and repeating the operation in a circulating mode until all sampling information weights corresponding to all angles in the angle set are calculated.
In the following, a possible way to determine the weights of the sampled information will be described.
For example, as shown in fig. 3, the total number of terminals determined in the cell is 4, and meanwhile, the total number of sampling times is 200, and the weight α of the set number of terminals is 0.5; the sampling frequency weight beta is 0.5; the number of sampling positions shown in the currently defined coverage range is 4:
the sampling position 1 is the sampling position of mr information data reported by the terminal 1 for 6 times;
the sampling position 2 is the sampling position of mr information data reported by the terminal 1 for 5 times;
the sampling position 3 is the sampling position of mr information data reported by the terminal 2 for 3 times;
the sampling position 4 is the sampling position of mr information data reported by the terminal 3 for 8 times;
sampling information weight
The weight of the sampling information is disclosed by substituting the data into the weight of the sampling information
After all sampling information weights P corresponding to all angles in the set angle set are determined through the method, the obtained information weights are compared with the minimum information weight which can meet the user requirements under cell coverage, and the lobe width is determined.
Optionally, selecting the sampling information weight which is greater than the weight threshold and is the smallest from the sampling information weights corresponding to all coverage areas; and taking the angle corresponding to the selected sampling information weight as the lobe width of the cell.
Therefore, when the sampling information weight is greater than the minimum information weight which can meet the user requirement under the cell coverage, the sampling information weight is selected to be greater than the minimum information weight which can meet the user requirement under the cell coverage, and the sampling information weight which is greater than the minimum information weight which can meet the user requirement under the cell coverage and is the smallest is selected from the sampling information weights; and the angle corresponding to the selected sampling information weight is used as the lobe width of the cell, so that more accurate coverage can be realized.
For example:
when the determined sampling information weight is larger than the minimum information weight which can meet the user requirements under the cell coverage, the number of the sampling information weights is 3, and the sampling information weights are respectively as follows:
the selected angle from the set angle set is 45 degrees, the coverage range is obtained by rotating the initial position for 5 times, and the weight value of the sampling information corresponding to the coverage range is 0.6;
the selected angle from the set angle set is 60 degrees, the coverage range is obtained by rotating the initial position for 5 times, and the weight value of the sampling information corresponding to the coverage range is 0.65;
selecting an angle of 75 degrees from the set angle set, rotating the initial position for 5 times to obtain a coverage range, wherein the weight value of sampling information corresponding to the coverage range is 0.7;
determining that the weight value of the selected sampling information is 0.6, and the angle corresponding to the weight value of the sampling information is 45 degrees, and taking the 45 degrees as the lobe width of the cell.
After the lobe width of the cell is determined, the azimuth angle of the cell is further determined according to the determined lobe width and the determined sampling information weight.
Optionally, the determining the azimuth angle of the cell according to the number of terminals in the cell, the sampling position of at least one terminal in the cell, and the sampling times at the sampling position includes:
selecting the coverage range with the maximum corresponding sampling information weight from all coverage ranges determined by the angles corresponding to the selected sampling information weights;
and taking the rotation angle of the coverage range relative to the initial coverage range as the size of the azimuth angle of the cell, and taking the direction of the angular rotation of the coverage range as the direction of the azimuth angle of the cell.
In the method, when the azimuth angle of a cell is determined, the coverage range with the maximum corresponding sampling information weight is selected from all coverage ranges determined by the angle corresponding to the selected sampling information weight; and taking the rotation angle of the coverage range relative to the initial coverage range as the size of the azimuth angle of the cell, and taking the direction of the angular rotation of the coverage range as the direction of the azimuth angle of the cell. Thus, after the lobe width which can meet the user requirement and realize accurate coverage is determined, the largest sampling information weight is selected from all the sampling information weights corresponding to the lobe width, the rotation angle of the coverage range relative to the initial coverage range under the sampling information weight is determined, the angle is used as the size of the azimuth angle of the cell, and the rotation direction of the coverage range angle is used as the direction of the azimuth angle of the cell. In this way, the coverage of the cell antenna can be made best at the determined lobe width.
For example, when it is determined that the lobe width is 45 °, when the weight of the sampled information corresponding to the coverage area obtained by rotating the initial position 5 times by a fixed angle of 30 ° each time is the largest, 150 ° is taken as the magnitude of the azimuth angle of the cell, and the direction of rotation of the coverage area is taken as the direction of the azimuth angle of the cell.
After the azimuth angle of the cell is determined, the downtilt angle of the cell is also determined in the embodiment of the present invention, so as to implement further accurate coverage.
Optionally, the determining the downtilt of the cell according to the position and height of the base station to which the cell belongs, the position and height of the base station to which the neighboring cell belongs, and the determined lobe width includes:
determining coverage boundary points of the cell and the adjacent cell according to the position and the height of the base station to which the cell belongs and the position and the height of the base station to which the adjacent cell belongs;
and determining the downtilt angle of the cell according to the distance from the coverage boundary point to the base station to which the cell belongs, the height of the base station to which the cell belongs and the determined lobe width.
When determining the cell downward inclination angle, firstly, determining the coverage boundary points of the cell and the adjacent cell according to the position and the height of the base station to which the cell belongs and the position and the height of the base station to which the adjacent cell belongs; and then determining the downtilt angle of the cell according to the distance from the coverage boundary point to the base station to which the cell belongs, the height of the base station to which the cell belongs and the determined lobe width. Therefore, the downward inclination angle corresponding to the cell is directly calculated through the known parameters, and the coverage range of the antenna of the cell adjusted according to the downward inclination angle is more accurate.
The position and height of the base station to which the cell belongs and the position and height of the base station to which the adjacent cell belongs can be obtained by obtaining the existing networking parameters, and the position of the base station to which the cell belongs and the position of the base station to which the adjacent cell belongs are determined by the longitude and latitude of the base station to which the cell belongs and the longitude and latitude of the base station to which the adjacent cell belongs in the existing networking parameters.
As shown in fig. 4, in a specific implementation, the positions of the base stations of all the cells are shown in a diagram according to the latitude and longitude information of the base station to which the cell belongs in the current networking engineering, and then the neighboring cells of the cell are determined according to the diagram.
Further, connecting the position of the base station to which the cell belongs with the position of the base station to which the adjacent cell belongs, and determining a boundary point S of the cell coverage according to the height of the base station to which the cell belongs and the height of the base station to which the adjacent cell belongs; that is, the distance from the boundary point S to the position A of the base station to which the cell belongs and the height H of the base station to which the cell belongs A Is equal to the distance between the boundary point S and the position F of the base station to which the adjacent cell belongs and the height H of the base station to which the adjacent cell belongs F The ratio of (A) to (B);
the downward inclination angle satisfies the formula:
at this time, after the vertical half angle θ (i.e., the lobe width) of the antenna is determined, the down tilt angle is determined
In addition, in a specific implementation, a coverage direction of the cell antenna may be different from a direction of a connection line between the base station to which the cell belongs and the base station to which the neighboring cell belongs, and at this time, since a coverage range of the antenna changes, the coverage range of the cell antenna may not reach the boundary point S, and at this time, whether to correct the downtilt angle of the cell needs to be considered.
Optionally, after determining the downtilt angle of the cell according to the distance from the coverage boundary point to the base station to which the cell belongs, the height of the base station to which the cell belongs, and the determined lobe width, the method further includes:
determining a connection between a base station to which the cell belongs and a base station to which the adjacent cell belongs;
and if the included angle between the connecting line and the azimuth angle of the cell is smaller than a set angle, correcting the downward inclination angle according to the azimuth angle of the cell.
In the method, after the downward inclination angle of the cell is determined, the connection between the base station to which the cell belongs and the base station to which the adjacent cell belongs is also determined; and if the included angle between the connecting line and the azimuth angle of the cell is smaller than a set angle, correcting the downward inclination angle according to the azimuth angle of the cell. Thus, after the downtilt of the cell is determined according to the distance from the coverage boundary point to the base station to which the cell belongs, the height of the base station to which the cell belongs and the determined lobe width, if a connection line between the base station to which the cell belongs and the base station to which an adjacent cell belongs is determined, and an included angle between the connection line and the azimuth angle of the cell is determined to be within a tolerable angle deviation range, the downtilt is corrected according to the determined azimuth angle, so that after the antenna corresponding to the cell is adjusted according to the determined azimuth angle, downtilt and lobe width, the coverage range of the cell antenna can be more accurate.
The tolerable angle deviation range is determined manually and is an empirical value, and different environments correspond to different tolerable angle deviation ranges.
In a specific implementation, as shown in fig. 5, when a deviation angle between a coverage direction of a cell antenna and a direction of a connection line between a base station to which the cell belongs and a base station to which an adjacent cell belongs is within a tolerable angle deviation range, the downtilt angle is corrected according to an azimuth angle of the cell, so that the coverage range of the cell antenna can cover a boundary point.
When the deviation angle between the coverage direction of the cell antenna and the direction of the connection line between the base station to which the cell belongs and the base station to which the adjacent cell belongs is within the tolerable angle deviation range, the boundary point of the cell antenna on the connection line between the base station to which the cell belongs and the base station to which the adjacent cell belongs is fixed, and the corresponding downward inclination angle of the coverage range of the cell antenna on the connection line at the moment
And the included angle between the connecting line and the azimuth angle of the cell is equal to half of the azimuth angle, and the azimuth angle meets the formula:
and after the downward inclination angle is corrected, immediately adjusting the antenna corresponding to the cell according to the determined azimuth angle, the downward inclination angle and the lobe width.
