However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art.

These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.
Based on the background, there is a problem that there is an error between the azimuth angle and the actual angle in the related art.
Antenna azimuth is an important engineering parameter, and if the engineering parameter is inaccurate, the network optimization work is greatly negatively affected.
The number of base stations in the current mobile network is large, the basic data volume to be maintained is large, a large amount of manpower and material resources are often required to be spent for testing and calibrating to acquire the actual engineering parameters of the current network, and the efficiency and the accuracy are low. The basic data acquisition, checking and calibration work is always one of the high-cost and low-yield works in the wireless network optimization.
In view of the above problems, the method for measuring and calculating the azimuth angle of the antenna provided by the embodiment of the present disclosure may determine the azimuth angle of the base station antenna based on the parameter data of the base station antenna and the measurement report MR data of the terminal, in combination with the relationship between RSRP and the antenna distance and angle. The azimuth angle of the antenna obtained in this way is more accurate, and after the engineering parameters are corrected by using the azimuth angle, the engineering parameters can be used for optimizing the network.
For ease of understanding, the following first describes terms and related techniques involved in the present disclosure.
MR (Measurement Report ) MR is one of the main grounds for evaluating the quality of a wireless environment. For the GSM system, MR is a main means for obtaining wireless information of a terminal at a network side, and mainly includes uplink signal information and downlink signal information.
The downlink signal information is measured and collected by a network terminal and reported to the network through MR signaling of a Um port; the uplink signal information is measured and collected by BTS at the network side, and the BTS gathers the uplink and downlink measurement information and reports the information to BSC through MR. The uplink and downlink signal information may specifically include RSRP (Reference Signal Receiving Power, reference signal received power), reference signal received quality, time advance, eNodeB antenna arrival angle, eNodeB received interference power, and the like.
RSRP is one of the key parameters that can represent the radio signal strength and the physical layer measurement requirements in an LTE network, and is the average value of the signal power received on all REs (resource elements) that carry reference signals within a certain symbol.
The base station generally comprises a BBU (Building Baseband Unite, indoor baseband processing unit), an RRU (Remote Radio Unite, remote radio frequency module) and an antenna feed system.
The BBU is generally arranged in a machine room in a centralized way, and the RRU is generally mounted by holding a pole or hanging a wall. The RRU mainly completes the modulation and demodulation of the radio frequency signals, the power amplification of the radio frequency analog signals and the transmission to the antenna feed system.
The antenna feed system comprises an antenna and a feeder, wherein the antenna is connected with the RRU through the feeder. The antenna can be installed on the iron tower, and a plurality of antennas can be installed on the iron tower of a base station.
It should be noted that, according to the base station, the corresponding installation mode of the antenna in the embodiment of the present disclosure may be different, and is not limited to being installed in the iron tower.
The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of base station capable devices may vary, for example in LTE systems, called enodebs or enbs; in a 5G NR-U system, it is called gNodeB or gNB.
In some scenarios, a "base station" may also be referred to as a "cell". As communication technology evolves, the description of "base station" may change.
There are many types of antennas. For example, by wavelength, medium wave antennas, short wave antennas, ultra-short wave antennas, microwave antennas, etc. may be included; according to performance, the antenna can comprise a high gain antenna, a medium gain antenna and the like; the directional antenna can comprise an omni-directional antenna, a sector antenna and the like; according to the purposes, the antenna can comprise a base station antenna, a television antenna, a radar antenna, a radio station antenna and the like; the antenna can comprise a line antenna, a surface antenna and the like according to the structure; depending on the type of system, it may include unit antennas, antenna arrays, etc.
The antenna in the embodiments of the present disclosure may be a directional antenna or a sector antenna as described above.
As one example, the antenna in embodiments of the present disclosure may be a plate-shaped directional antenna. The plate-shaped directional antenna may comprise a radiating element, a reflecting plate, a power distribution network.
Here, the radiating element may be a vibrator, the reflecting plate may be a bottom plate, and the power distribution network may be a feeding network.
In addition, the antenna may also include packaging protection, such as radomes.
When radio waves propagate in space, the electric field direction changes according to a certain rule, and this phenomenon is called polarization of the radio waves.
Dual polarization, i.e. 2 antenna elements in one unit, forms two independent waves. By adopting the dual-polarized antenna, the number of antennas can be reduced when a cell is covered, the requirement on the conditions of antenna erection is reduced, the investment is further reduced, and the coverage effect can be ensured.
Among the characteristics of the antenna, a very important capability is the radiation distance. The radiating distance of the antenna can be further increased by adding the vibrator.
In cities, the crowds are dense, and buildings stand up, and directional antennas are usually required to cover a specified range. And a reflecting plate blocked at one side. Then, a plurality of vibrators are combined, and "focusing" can be performed.
The antenna body is typically mounted at a high elevation with a downward inclination, and the azimuth to be measured in the embodiments of the present disclosure is the azimuth when the antenna is mounted.
The method for measuring and calculating the antenna azimuth angle provided by the embodiment of the disclosure can be executed by any electronic equipment with calculation processing capability. For example, the execution body of the network traffic feature extraction method may be, but not limited to, any terminal device, server, or the execution body of the method that can be configured to execute the method for measuring and calculating the antenna azimuth provided by the embodiments of the present disclosure, or may be a client itself that can execute the method.
The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs (Content Delivery Network, content delivery networks), basic cloud computing services such as big data and artificial intelligent platforms, and the like.
The terminal may be a variety of electronic devices including, but not limited to, smartphones, tablets, laptop portable computers, desktop computers, wearable devices, augmented reality devices, virtual reality devices, etc., which are not limited herein.
The present exemplary embodiment will be described in detail below with reference to the accompanying drawings and examples.
Fig. 1 shows a flowchart of a method for measuring and calculating an azimuth angle of an antenna in an embodiment of the disclosure, as shown in fig. 1, the method for measuring and calculating an azimuth angle of an antenna provided in the embodiment of the disclosure includes the following steps:
step S102, acquiring industrial parameter data of a base station antenna and measurement report MR data of a terminal, wherein the MR data comprises reference signal received power RSRP;
step S104, based on the parameter data of the base station antenna and the measurement report MR data of the terminal, combining the relation between RSRP and the antenna distance and angle, determining the azimuth angle of the base station antenna.
The following describes the above steps in detail, as follows:
in some embodiments, determining the azimuth angle of the base station antenna based on the parameter data of the base station antenna and the measurement report MR data of the terminal in combination with the RSRP versus antenna distance and angle may include:
determining a coverage sector of the base station antenna based on the industrial parameter data of the base station antenna and the measurement report MR data of the terminal by combining the relation between RSRP and the antenna distance and angle;
based on the coverage sector of the base station antenna, the azimuth angle of the base station antenna is determined in combination with the MR data in the sector.
In some embodiments, the parametric data may include sector locations and sector transmit powers, and the MR data may also include terminal locations.
Accordingly, determining the coverage sector of the base station antenna based on the parameter data of the base station antenna and the measurement report MR data of the terminal in combination with the relation between RSRP and the antenna distance and angle may include:
based on the terminal position, carrying out aggregation processing on the MR data to obtain a distribution diagram of the MR data;
based on the MR data distribution diagram, combining the relation between the sector position, the sector transmitting power and the RSRP and the antenna distance and angle, the coverage sector of the base station antenna is determined.
The "position" in the above embodiment may specifically be latitude and longitude information.
In some embodiments, the tool data may also include a base station ID and a sector ID, and the MR data may also include a base station ID and a sector ID.
Before determining the coverage sector of the base station antenna based on the profile of MR data in combination with the relationship of sector location, sector transmit power, and RSRP to antenna distance and angle, the method may further comprise:
based on the base station ID and the sector ID, the industrial parameter data and MR data are associated.
As an example, as shown in fig. 2, the industrial parameter data may include a base station ID, a sector ID, a latitude and longitude of a sector, and a sector transmission power; AGPS MR data may include base station ID, sector ID, RSRP signal strength, and location data (longitude and latitude) of signals received by a plurality of handset terminals in each sector.
Fig. 3 shows the geographical distribution of AGPS MR data, i.e. the MR data obtained by aggregating the MR data based on the terminal position as described above. In this profile, each gray dot corresponds to 1 or more pieces of MR data.
As an example, where MR data is aggregated, a DBSCAN algorithm may be applied.
In the azimuth calculation process, a machine learning algorithm is required to cluster grids, and a DBSCAN algorithm is adopted here: the core idea of the DBSCAN is to start from a certain core point and continuously expand towards a region with reachable density, so that a maximized region comprising the core point and the boundary point is obtained, and any two points in the region are connected with each other in density. The algorithm is introduced as follows:
DBSCAN (Density-Based Spatial Clustering of Applications with Noise, density-based clustering method with noise) is a typical Density clustering algorithm, and the basic concept involved is as follows:
1. epsilon-neighborhood: for xj ε D, its ε -neighborhood contains the sub-sample set in sample set D that is no more than ε away from xj.
2. Core object: for any sample xj e D, if N e (xj) corresponding to its e-neighborhood contains at least MinPts samples, i.e., if |N e (xj) |gtoreq MinPts, xj is the core object.
3. The density is direct: if xi is located in the E-neighborhood of xj and xj is the core object, then xi is said to be directly reached by xj density.
4. The density can be achieved: for xi and xj, if there are sample sequences p1, p2,..pt satisfies p1=xi, pt=xj, and pt+1 is directly reached by pT density, then xj is said to be reachable by xi density. That is, the density can be satisfied with the transferability.
5. Density connection: for xi and xj, if there is a core object sample xk, let both xi and xj be reachable by xk density, then we call xi and xj density connected.
DBSCAN requires two parameters: epsilon (eps) and the minimum number of points (minPts) needed to form a high density region, starting with an arbitrary point that is not accessed, then exploring the epsilon-neighborhood of this point, if there are enough points in the epsilon-neighborhood, creating a new cluster, otherwise this point is labeled as noise. Note that this point may then be found in the e-neighborhood of other points, and that the e-neighborhood may have enough points at which time this point will be added to the cluster.
If a point is located in a dense region of a cluster, its e-neighborhood points also belong to the cluster, and when these new points are added to the cluster, if it(s) are also in the dense region, its e-neighborhood point(s) are also added to the cluster. This process is repeated until no more points can be added, so that a densely connected cluster is completely found. Then, an unaccessed point will be explored to find a new cluster or noise.
The DBSCAN algorithm can be abstracted into the following steps:
1. finding out the points in the E-neighborhood of each point, and finding out the core points with more than minPts neighborhood.
2. The connected components of the core points are found on the adjacent graph, and all non-core points are ignored.
3. And (3) each non-core point is allocated to nearby epsilon neighbor clusters, and if not, the non-core points are allocated to noise.
In some embodiments, determining the azimuth of the base station antenna based on the coverage sector of the base station antenna in combination with MR data within the sector comprises:
rasterizing an image corresponding to a coverage sector of a base station antenna to obtain a plurality of grids;
dividing a plurality of grids into a plurality of distance intervals according to the distance between each grid and a base station;
according to MR data contained in each grid, calculating to obtain the weight of each grid;
determining a reference point in grids contained in the distance interval according to the weight of each grid;
an azimuth angle of the base station antenna is determined based on the location of the reference point and the location of the base station.
As shown in FIG. 2, an MR data rasterization process is also included in embodiments of the present disclosure.
As an example, for computational efficiency and geographical presentation, MR data is rasterized according to longitude and latitude, as follows:
Referring to fig. 4, an mr data rasterization schematic diagram is shown. The longitudinal direction of the earth is divided into large grids in units of 6 longitudes and the transverse direction is divided into large grids in units of 3 latitudes, and each large grid is a large area and is represented by earth_id. Each large area is divided into small grids according to different grid side lengths (e.g. 20 meters) by taking the center as an origin, and x_offset and y_offset are coordinates of each small grid in the large area, namely three values of earth_id, x_offset and y_offset can determine each grid on the earth.
In the foregoing, based on the base station ID and the sector ID, the industrial parameter data and the MR data are associated, specifically, the MR raster data and the industrial parameter data are associated, and the AGPS MR raster corresponding to each sector is obtained by associating the AGPS MR raster data and the industrial parameter data through the base station ID and the sector ID fields.
As shown in fig. 5, in the sector covered by the antenna, the RSRP value is larger in the MR near the antenna azimuth axis among MR points close to the base station. The color shading at the points in fig. 5 represents RSRP intensity. The point A is the base station position, and the line AB is the antenna azimuth facing direction.
As an example, in the foregoing, the specific procedure for measuring azimuth angle is as follows:
mr data clustering and filtering:
And clustering the MR grids under the sector by using a DBSCAN algorithm according to longitude and latitude, reserving clustering core points and non-core points, and eliminating the external points (noise).
2. Azimuth calculation:
(1) the grids in the coverage area of the sector are sorted from small to large according to the distance between the grids and the base station, and are divided into a plurality of distance intervals with the same number;
(2) within each distance interval, the weight of each grid is calculated according to the characteristics of the grid, such as the average RSRP value and the number of MR contained in the grid, and the calculation formula is as follows:
w=rsrp×(log(cnt)+1) (1)
where w represents the weight of each grid, RSRP represents the average RSRP value, cnt represents the number of MR contained in the grid.
(3) Determining a reference point in grids contained in the distance interval according to the weight of each grid;
(4) an azimuth angle of the base station antenna is determined based on the location of the reference point and the location of the base station.
The reference point may be a grid with the greatest weight in each distance interval.
As one example, determining the azimuth of the base station antenna based on the location of the reference point and the location of the base station may include:
respectively calculating azimuth angles between the base station and a plurality of reference points to obtain a plurality of first azimuth angles;
an azimuth angle of the base station antenna is determined based on the plurality of first azimuth angles.
Here, the azimuth angle between the base station and the reference point is first calculated.
Let the coordinates of the base station and the reference point be (x) 1 ,y 1 ) And (x) 2 ,y 2 ) The azimuth angle α can be calculated by the following formula:
α=atan2(x 2 -x 1 ,y 2 -y 1 ) (2)
the predicted azimuth, i.e. the actual azimuth of the base station antenna, can then be calculated from the average of the base station and the reference point azimuth.
Figure BDA0003432308180000111
In some embodiments, after obtaining the azimuth of the base station antenna, the azimuth correction list may be further output, and the antenna azimuth in the parameter data may be calibrated based on the azimuth of the base station antenna.
As an example, the predicted azimuth angle and the azimuth angle of the industrial parameter sector are compared according to the following formula, when the angle deviation is larger than delta, the azimuth angle of the sector in the basic database is judged to be inconsistent with the actual installation azimuth angle on site, an azimuth angle correction list is output, and industrial parameter calibration is carried out according to the predicted actual azimuth angle.
Prediction angle-reference sector azimuth angle | > delta (delta is the angular deviation threshold)
The RSRP is an important characteristic of MR data, a strong correlation exists between the spatial distribution of the RSRP value and the actual azimuth of the sector, and the method is more accurate than a common prediction method through measuring and calculating the azimuth of the sector by the MR position processed by the RSRP value of the MR and the AI big data machine learning algorithm.
By the method provided by the embodiment of the disclosure, the automatic checking and calibration of the antenna azimuth angle can be realized, the accuracy of basic data management is improved, the wireless network planning and the optimizing work are accurately enabled to be carried out, a large amount of manual testing cost is saved, the cost reduction and synergy are realized, and the method has the characteristics of high updating frequency, high efficiency and high accuracy.
For ease of understanding, the method of measuring antenna azimuth in the present disclosure will be described in detail below with reference to the accompanying drawings as a specific example.
Clustering MR grids under the sector according to longitude and latitude by using a DBSCAN algorithm, selecting parameters E=0.01 and minPts=5, and eliminating the external points.
As shown in fig. 6, the grids in the coverage area of the sector are sorted from small to large according to the distance between the grids and the base station, and the grids are equally divided into 10 distance intervals after weight removal.
Within each distance interval, the weight (w) of each grid is calculated according to the average RSRP value (RSRP) of the grid and the MR number (cnt) contained in the grid, and the mode is calculated according to the formula (1) in the foregoing.
Selecting a grid with the largest weight in each distance interval as a reference point, and calculating azimuth angles between the base station and the reference point, wherein five-pointed star is used for calculating the reference point for the azimuth angle with the largest weight in each distance interval in FIG. 7;
The predicted azimuth angle is calculated according to the average value of the azimuth angles of the base station and the reference point, and as shown in fig. 8, the midpoint M is the base station position, and the line segment direction is the predicted azimuth angle, namely the azimuth angle of the base station antenna.
According to the method, the device and the system, the MR measurement information and the base station position information of a large number of mobile phone terminals are collected, the characteristic of the spatial distribution of the RSRP intensity of the 4G MR is utilized, an AI big data machine learning algorithm is combined, an accurate antenna azimuth angle is obtained, then the antenna azimuth angle is compared with the antenna azimuth angle in engineering parameters for analysis, automatic deviation correction of the antenna azimuth angle in the engineering parameters is achieved, the basic data management accuracy is improved, and the wireless network planning and optimizing work is accurately enabled.
