Due to the accuracy of the antenna direction angle of the base station, the wireless network coverage level is closely related to the wireless network coverage level. Therefore, checking or determining the antenna direction angle parameter becomes a concern.

Specifically, (1) a drive test mode; the method comprises the steps that the output power of a base station providing service for a terminal is detected by a network side through the signal strength reaching the terminal, the antenna gain value is calculated through the antenna feeder loss and the signal loss under an ideal wireless environment, the signal strength of a plurality of terminals at multiple angles is determined through a drive test mode, the antenna gain values at different angles are determined, and the angle with the maximum antenna gain value is the direction angle of the antenna. For example, as shown in fig. 1, signal strength Y ═ output power X-antenna feed loss + antenna gain G-signal loss Z; the gain of the reverse antenna is: and the antenna gain G is equal to the signal intensity Y-output power X + antenna feeder loss + signal loss Z. Therefore, the angle at which the antenna gain is maximum is the antenna direction angle. (2) Frequency sweep + communication mode; aiming at some terminals in a target base station, the signal intensity of main frequency carrier signals of all cells of the target base station is obtained by adopting frequency sweep, and a field intensity diagram of the target base station is restored according to the signal intensity, so that the antenna direction angle is determined, wherein the field intensity diagram can be as shown in fig. 2 (including a qualified field intensity diagram and an unqualified field intensity diagram), and meanwhile, a hidden fault of the main frequency carrier is found aiming at the terminal which is in communication in the target base station by adopting a communication and frequency locking communication mode, so that the target base station is comprehensively tested, and the antenna direction angle of the target base station is determined.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
It should be noted that the device for determining the antenna direction angle in the embodiment of the present invention may be an independent device that can communicate with the base station and the network side, or may be a module integrated in a network-side device to determine the antenna direction angle.
Example one
An embodiment of the present invention provides a method for determining an antenna direction angle, which is described by taking the apparatus for determining an antenna direction angle as a network side as an example, and as shown in fig. 3, the method may include:
s101, in a first area, counting the number of sampling points at each angle and the signal strength of each sampling point according to antenna frequency sweep data of an angle level, wherein the antenna frequency sweep data are obtained by scanning the first area.
In the embodiment of the present invention, because the setting parameter of the antenna direction angle in the existing network is determinable or obtainable, after the antenna is installed, the network side checks or determines the installed actual antenna direction angle to determine the error between the actual antenna direction angle and the desired antenna direction angle in the existing network. The determination of the antenna direction angle provided by the embodiment of the invention refers to the determination of the actual antenna direction angle.
In the embodiment of the present invention, the network side determines the antenna direction angle for one area or an area range (first area). That is, in the first area, the network side analyzes the network coverage by determining the antenna direction angle, and the number of terminals or base stations covering the first area in the first area is variable and can be analyzed according to actual situations.
Optionally, the first area is a region range, which may be an area of several kilometers in a square circle or an area of a city, and the specific embodiment of the present invention is not limited.
Specifically, in the first area, the network side may sweep frequency of the first area to obtain antenna sweep frequency data about different angles in the first area, and therefore, the network side may count the number of sampling points at each angle and the signal strength of each sampling point according to the antenna sweep frequency data at an angle level.
It should be noted that, the sampling points in the embodiment of the present invention refer to terminals at different angles in the first area, one terminal may be one sampling point, the number of terminals at one angle is the number of sampling points at the angle, and the signal strength of a terminal at one angle in the network is the signal strength of a sampling point at the angle.
It can be understood that the antenna frequency sweep data at different angles in the embodiment of the present invention may be antenna frequency sweep data at 0 to 360 degrees, and the network side obtains information corresponding to a plurality of sampling points by scanning the antenna frequency sweep data at 0 to 360 degrees, and since there may be a plurality of sampling points at one angle, the network side performs statistics on the related information of the sampling points to obtain the number of the sampling points at each angle and the signal strength of each sampling point.
S102, determining M antenna radiation lobes according to the number of sampling points at each angle, wherein M is larger than or equal to 1.
After the network side counts the number of sampling points at each angle and the signal strength of each sampling point according to the antenna frequency sweeping data of the angle level, the network side knows the number of sampling points at each angle, so that the network side can determine at least one antenna radiation lobe by judging the number of sampling points at each angle.
Specifically, in the embodiment of the present invention, the method for determining M antenna radiation lobes by the network side according to the number of sampling points at each angle may include, as shown in fig. 4: S1021-S1022. The method comprises the following specific steps:
and S1021, judging a first angle interval with sampling points on M continuous angles according to the number of the sampling points on each angle.
And S1022, determining M antenna radiation lobes by taking each first angle interval as one antenna radiation lobe.
It should be noted that the network side sequentially determines the number of the sampling points at each angle, and when the network side determines that the number of the sampling points at consecutive angles is not 0, the network side determines a first angle interval formed by the consecutive angles as an antenna radiation lobe. Since at least one (i.e., M) antenna radiation lobes can be determined within the range of 0-360 degrees in the first angle interval, the network side in the embodiment of the present invention can determine M antenna radiation lobes.
For example, in the antenna directivity diagram of the first region shown in fig. 5, data in the circumferential direction represents a degree value, and data in the vertical direction represents a signal strength value. As can be seen from the figure, the data of the 0 ° up-sampling points is not zero, and the determination is performed according to each step length +1 °, n degrees until the number of the n ° up-sampling points is 0 is a first angle interval, that is, an antenna radiation lobe, and the beam width of the antenna radiation lobe is n ° -0 ° -n °; then, continuing to judge according to the step length +1 degrees, and if the number of sampling points is 0 until n degrees +/-j-1 degrees, indicating that no sampling point exists in the angle interval and no antenna radiation lobe (radiation lobe/radiation energy) exists; when the angle of n ° + j ° is reached, the sampling point reappears, the judgment is continued according to the step length +1 °, when the angle of n ° + k ° is reached, the frequency sweeping sampling point becomes zero again, a second antenna radiation lobe appears, and the beam width of the antenna radiation lobe is: n ° + k ° -j °; and thus, continuously judging according to the step length of +1 degrees until all the 360 degrees are judged. As shown in fig. 5, the network determines a total of 7 antenna radiation lobes in the first area by determining the number of sampling points at each angle.
S103, determining an antenna radiation main lobe from the M antenna radiation lobes according to the signal intensity of each sampling point and the number of the sampling points at each angle.
After the network side determines the M antenna radiation lobes according to the number of the sampling points at each angle, because the number of the sampling points at each angle and the signal strength of each sampling point are different, the network side can calculate a total value representing the overall signal strength of one antenna radiation lobe according to the signal strength of each sampling point and the number of the sampling points at each angle, and the network side can select the highest total value of the signal strength according to the total value of the signal strength of each antenna radiation lobe in the M antenna radiation lobes, and the antenna radiation lobe corresponding to the highest total value of the signal strength is the antenna radiation main lobe.
Specifically, in the embodiment of the present invention, the method for determining the antenna radiation main lobe from M antenna radiation lobes by the network side according to the signal strength of each sampling point and the number of sampling points at each angle, as shown in fig. 6, may include: S1031-S1034. The method comprises the following specific steps:
and S1031, calculating a first proportion of the total number of the first sampling points in each antenna radiation lobe to the total number of the second sampling points in all angles in the first area according to the number of the sampling points in each angle.
S1032, determining a first signal strength value with the strongest signal strength of the sampling point in each antenna radiation lobe according to the signal strength of each sampling point.
S1033, calculating a first signal strength total value of the M antenna radiation lobes according to the M first proportions and the M first signal strength values, wherein the M first proportions are in one-to-one correspondence with the M first signal strength values.
S1034, determining a first signal strength total value with the highest value from the M first signal strength total values, wherein an antenna radiation lobe corresponding to the highest first signal strength total value is an antenna radiation main lobe.
Specifically, because the number of sampling points at each angle is different, the number of sampling points in each antenna radiation lobe is not necessarily the same, and thus, the network side can calculate a first proportion that the total number of first sampling points in each antenna radiation lobe accounts for the sum of second sampling points at all angles in the first area; and the network side can determine a numerical value (first signal strength value) with the highest signal strength of the sampling point in each antenna radiation lobe, and calculate a first signal strength total value of the M antenna radiation lobes according to the formula (1), wherein an antenna radiation lobe corresponding to the highest first signal strength total value in the M first signal strength total values is the antenna radiation main lobe in the first area. Wherein, the formula (1) is as follows:
G＝a％*RSRP_max (1)
wherein, a% is a ratio (i.e. a first ratio) of the number of sampling points in each antenna radiation lobe to the number of sampled points in the first region, RSRP _ max is a strongest signal value (i.e. a first signal strength value) of the sampling points in the antenna radiation lobe, and G is a first signal strength total value of the antenna radiation lobe.
For example, assuming that there are M radiating lobes, the network side may calculate M G values altogether, and take the antenna radiating lobe corresponding to max (G) as the antenna radiating main lobe.
And S104, determining an angle value of the antenna direction angle according to the signal strength of the sampling point in the antenna radiation main lobe.
After the network side determines the antenna radiation main lobe from the M antenna radiation lobes according to the signal strength of each sampling point and the number of the sampling points at each angle, the network side can determine the angle value of the antenna direction angle according to the signal strength of the sampling points in the antenna radiation main lobe.
Specifically, the network side determines an angle value corresponding to a first signal strength value in the main lobe of the antenna radiation as an angle value of an antenna direction angle.
For example, as shown in fig. 7, the antenna radiation main lobe determined by formula (1) at the network side is an antenna radiation lobe 1, and the first signal strength value in the antenna radiation lobe 1 is an angle value of an antenna direction angle, such as an angle value indicated by an arrow in fig. 7.
Further, as shown in fig. 8, after S104, the method for determining the antenna direction angle according to the embodiment of the present invention may further include: and S105. The method comprises the following specific steps:
and S105, calculating the deviation of the antenna direction angle according to the determined angle value of the antenna direction angle and the angle value of the antenna direction angle in the current network for reference during network optimization.
After the network side determines the angle value of the antenna direction angle according to the signal strength of the sampling point in the antenna radiation main lobe, because the angle value of the antenna direction angle to be set is stored in the existing network antenna parameter database before the antenna is installed, and the installed actual antenna direction angle has deviation from the antenna direction angle in the existing network due to various reasons in the process of installing the antenna, after the network side determines the actual antenna direction angle, the network side can calculate the deviation of the antenna direction angle according to the determined actual angle value of the antenna direction angle and the angle value of the antenna direction angle in the existing network, so that when the network is optimized, the network can be better improved according to the obtained deviation of the antenna direction angle to improve the network coverage.
For example, the network side records the angle value of the calculated antenna direction angle, and if the angle value is α and the angle value of the antenna direction angle recorded in the antenna parameter database in the existing network is β, the antenna direction angle error C calculated by the network side is abs (α - β). As shown in fig. 9, the dashed arrow is the actual antenna direction angle determined in the embodiment of the present invention, and the solid arrow is the antenna direction angle recorded in the antenna parameter database in the current network, so that C is the deviation or error of the antenna direction angle.
Further, as shown in fig. 10, before S101, the method for determining an antenna direction angle according to an embodiment of the present invention may further include: and S106. The method comprises the following specific steps:
and S106, scanning for 360 degrees from the initial angle of the first area according to a preset scanning strategy to obtain antenna frequency scanning data.
It should be noted that the sampling point and the acquisition of the relevant information of the sampling point in the embodiment of the present invention are obtained by the network side frequency sweep.
Specifically, in the antenna direction angle diagram of the first area, the network side may start scanning from 0 degree and scan to 360 degrees according to a frequency of 1 degree at an interval, so as to obtain the relevant antenna sweep data of the sampling point at 0-360 degrees.
According to the method for determining the antenna direction angle, provided by the embodiment of the invention, the number of sampling points at each angle and the signal strength of each sampling point are counted in a first area according to the antenna frequency sweeping data of angle levels, wherein the antenna frequency sweeping data is obtained by scanning the first area; determining M antenna radiation lobes according to the number of sampling points at each angle, wherein M is greater than or equal to 1; determining an antenna radiation main lobe from the M antenna radiation lobes according to the signal intensity of each sampling point and the number of the sampling points at each angle; and determining the angle value of the antenna direction angle according to the signal strength of the sampling point in the antenna radiation main lobe. By adopting the technical implementation scheme, aiming at the first area, the angle value of the antenna direction angle is intelligently judged by adopting a frequency sweeping and antenna radiation main lobe determining method for reference in subsequent network optimization, the antenna direction angle determining method is simple, feasible and efficient, and the accuracy and the timeliness of the antenna direction angle checking are improved.
