Description
Technical Field
The present invention relates to communications technologies, and in particular, to a method, an apparatus, a device, and a readable storage medium for determining an antenna feeder reverse connection.
Background
As communication technologies are continuously developed and upgraded, base stations exhibit various forms. In general, the composition of a base station site may include: the system comprises a directional antenna, a feeder line, a base station baseband processing unit and the like, wherein the directional antenna responsible for each sector is connected to a port of the corresponding sector of the base station baseband processing unit through the feeder line, so that the signal coverage of a preset sector direction angle is realized. In the installation and maintenance process of the base station, constructors need to install all the equipment of the base station site in place according to a designed scheme, but due to the fact that construction quality is uneven, the problem of antenna feedback connection is prone to occurring. The problem of antenna feed connection is that the feeder is completely connected, and referring to fig. 1, the correct connection is that the antenna 1 should be connected with the main set diversity of the sector 1 to form the signal coverage of the sector 1, and the antenna 2 should be connected with the main set diversity of the sector 2 to form the signal coverage of the sector 2. However, the antenna feeds of sector 1 and sector 2 in fig. 1 are completely reversed, and the physical appearance is that the coverage area and the geographic coverage direction of sector 1 and sector 2 are opposite. The reverse antenna feeder shown in fig. 1 will cause network drop and poor downlink quality, and also cause the problems of disordered Physical Cell Identity (PCI) planning of the current network. The problem that the feeder line is completely reversely connected is high in concealment and difficult to check.
For the judgment of the antenna feedback reverse connection, currently, the troubleshooting is usually performed based on the drive test or the troubleshooting is performed based on the switching direction angle positioning mode of the adjacent cell pair. And checking a switching direction angle positioning mode based on the adjacent cell pair, namely utilizing the switching simulation longitude and latitude weighted recalculation to obtain the simulation longitude and latitude, and then comparing the simulation longitude and latitude with the parameter information to find out the problem of inverse connection.
However, the existing judgment mode based on the drive test is long in time consumption and low in positioning and finding efficiency, and an area which cannot be traversed by a drive test vehicle cannot know whether the drive test vehicle is reversely connected or not, so that the error is large. And because of the adjacent cell pair-based switching direction angle positioning mode, the span of included angles among base station sectors is large, and in addition, the influence of backward switching on the simulation longitude and latitude easily causes the error of reverse judgment. Therefore, the accuracy and the efficiency of the existing antenna feeder reverse connection judgment method are not high.

The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
At present, in the process of base station construction and maintenance, problems of poor downlink quality, network disconnection and the like are caused by disordered PCI planning of the existing network due to indirect reflection of antenna feeder sectors, and user experience is finally influenced. The problem of complete reverse connection of antenna feeders (see fig. 1) is that the concealment is strong, so that the optimization accuracy is reduced, the troubleshooting is difficult, the time and the labor are consumed for the existing drive test positioning and the existing station-accessing troubleshooting, and the reverse judgment error is easily caused due to the fact that the included angle span between the sectors of the base station is large and the influence of the reverse switching on the simulated longitude and latitude is added to the switching direction angle positioning based on the adjacent cell pair.
In order to solve the problems of difficult judgment and low judgment efficiency of the antenna feeder connection in the prior art, the invention provides a method for judging the antenna feeder connection in the following various embodiments, which determines the actual coverage direction angle range of each sector in a base station to be detected according to the reported information collected from a user terminal and compares the actual coverage direction angle range with the preset sector direction angle planned for the base station to be detected, thereby quickly judging whether the base station to be detected has the situation of the antenna feeder connection, and effectively improving the identification accuracy and the positioning accuracy of the problem of the antenna feeder connection.
Referring to fig. 2, which is a schematic flowchart of a method for determining whether an antenna feeder is reversely fed according to an embodiment of the present invention, an execution main body of the method shown in fig. 2 may be a software and/or hardware device, for example, a server. The method shown in fig. 2 includes steps S101 to S103, which are specifically as follows:
s101, reporting information of a plurality of user terminals is obtained, wherein the reporting information indicates a sector and a user position of each user terminal accessing a base station to be tested.
Specifically, the remote drive test function may be deployed through software, and then the report information reported by the user terminal in the coverage area of the base station to be tested is collected within a preset time period, for example, the report information may be obtained from the base station to be tested. And determining the cell accessed by each user terminal and the user position information of the user terminal by analyzing the reported information. The user location information may be, for example, Global Positioning System (GPS) positioning information, Beidou satellite navigation system (BDS) positioning information, or other latitude and longitude information. The user terminal in this embodiment may be a mobile phone of a user, but is not limited to this, and may also be other electronic devices that can communicate with the base station and provide the reported information.
In some specific embodiments, the reporting information includes: the cell identification is the identification of the cell accessed by the user terminal. One sector can correspond to one or more cells, and according to the cell identifier in the reported information, which sector the user terminal corresponding to the reported information accesses can be determined, and then which sector the user position information in the reported information corresponds to can be determined, and dotting of a sampling position point is completed, so that an actual coverage direction angle range is determined for each sector in the next step.
S102, obtaining the actual coverage direction angle range of each sector according to the reported information.
Specifically, first, the user location information corresponding to each sector in the base station to be measured is determined according to the sector to which the cell identifier in each piece of reported information belongs. It can be understood that each user location information corresponds to a sampling location point, and the sampling location point corresponds to a sector of the base station to be measured, so that a plurality of sampling location points can be determined for each sector. Since the sector actually covers an area, in order to more accurately determine the actual coverage direction angle range of each sector, the method may be implemented by increasing the sampling position points, for example, collecting more reported information, and calculating the actual coverage direction angle range of each sector when the number of the reported information is greater than 500.
And then, determining the actual coverage direction angle range of each sector according to the base station position information of the base station to be detected and the user position information corresponding to each sector.
In some specific embodiments, it can be understood that the average value of the coverage direction angle corresponding to each sector is obtained according to the base station location information of the base station to be measured and the user location information corresponding to each sector. For example, the test base station has three sectors, and a mean coverage direction angle is determined for each sector. And then determining the actual coverage direction angle range of each sector according to the coverage direction angle average value corresponding to each sector.
In some embodiments, the process of obtaining the coverage direction angle average value corresponding to each sector may specifically be: and acquiring sampling angles corresponding to the user position information according to the base station position information of the base station to be detected and the user position information corresponding to each sector, wherein the sampling angles take the position indicated by the base station position information as an original point and take the north direction as a reference direction, and the values of the sampling angles increase clockwise to form a first quadrant, a second quadrant, a third quadrant and a fourth quadrant in sequence.
Fig. 3 is a sample angle example of each user location information corresponding to one sector according to an embodiment of the present invention. In the coordinate system shown in fig. 3, the direction from the origin to the north is 0 °, the direction from the origin to the east is 90 °, the direction from the origin to the south is 180 °, and the direction from the origin to the west is 270 °, wherein 0 ° to 90 ° is the first quadrant, 90 ° to 180 ° is the second quadrant, 180 ° to 270 ° is the third quadrant, and 270 ° to 0 ° is the fourth quadrant. In the example shown in fig. 3, the sampling position points corresponding to all the user position information in the same sector are all distributed in the first quadrant, the second quadrant, and the third quadrant, and then the sampling angles corresponding to all the sampling position points are averaged
The average value of the covering direction angle corresponding to the sector is obtained
Fig. 4 is a sample angle example of each user location information corresponding to another sector according to the embodiment of the present invention. Fig. 4 adopts the same coordinate system as fig. 3, but in the example shown in fig. 4, the sampling position points corresponding to the sector are distributed in the first quadrant and the fourth quadrant, and in order to improve the accuracy of the coverage direction angle average value, in this embodiment, after subtracting 360 ° from each sampling angle located in the fourth quadrant, averaging is performed with the sampling angles located in the other quadrants of the same sector, if the result of the averaging is positive, the result of the averaging is taken as the coverage direction angle average value corresponding to each sector, and if the result of the averaging is negative, the result of the averaging is added 360 ° to be taken as the coverage direction angle average value corresponding to each sector.
Optionally, after subtracting 360 ° from each sampling angle located in the fourth quadrant, before performing averaging processing with sampling angles located in other quadrants of the same sector, the method further includes: in all sampling angles corresponding to the same sector, the sampling angle ratio in the first quadrant and the fourth quadrant is greater than or equal to a preset ratio threshold. For example, the sampling position points are distributed in the first quadrant and the fourth quadrant, and the ratio of the sampling position points in the first quadrant and the fourth quadrant to the sampling position points used in the sector is greater than or equal to 20%, each sampling angle in the fourth quadrant is reduced by 360 ° before the averaging process, and after the averaging process, if the averaging process result is positive, the averaging process result is taken as the average value of the coverage direction angles corresponding to the sectors, and if the averaging process result is negative, the averaging process result is added by 360 ° and taken as the average value of the coverage direction angles corresponding to the sectors.
In some embodiments, the sector correspondences are obtained in any of the manners described aboveAfter the covering direction angle average value, determining the actual covering direction angle range of each sector according to the covering direction angle average value corresponding to each sector, which may include: firstly, according to the average value of the covering direction angles corresponding to the sectors, the interval estimation range of the covering direction angles corresponding to the sectors is obtained. And then, if the interval width of the interval estimation range is less than or equal to the preset antenna-3 dB half-power lobe width, determining the actual coverage direction angle range of each sector according to the interval estimation range of the coverage direction angle corresponding to each sector. For example, the standard deviation of the samples for n sampling angles for the sectors shown in FIG. 3 or FIG. 4 is calculated
The interval estimation range covering the direction angle is the double-sided (1-alpha) confidence interval of the overall mean value:
wherein the content of the first and second substances,
α is 0.05 and Z at a confidence level of 0.95 for 1- αα/2＝1.96。
The range of the coverage angle interval may be directly used as the actual coverage angle range of the sector, or the range of the coverage angle interval may be used as the actual coverage angle range of the sector after tolerance error is added on the basis of the range of the coverage angle interval estimation. In some embodiments, the actual coverage direction angle range of each sector is determined according to the interval estimation range of the coverage direction angle corresponding to each sector and a preset tolerance error. For example, after the obtained range estimation range of the coverage direction angle of each sector is respectively R1/R2/R3, considering the uncertainty of the base station sector actually being sector coverage and network users, a concept of tolerance and comparison interval is introduced, i.e. on the basis of the calculated R1/R2/R3, the tolerance is 1/2 with the antenna-3 dB half-power lobe width of 60 °, i.e. the tolerance is 30 degrees. And the comparison interval obtained through tolerance calculation is R11/R22/R33, and the comparison interval is used as the actual coverage direction angle range of the finally determined sector.
S103, acquiring an antenna feed reverse judgment result of the base station to be detected according to the preset sector direction angle of each sector and the actual coverage direction angle range of each sector.
Specifically, if the preset sector direction angle of each sector is matched with the respective actual coverage direction angle range, the no-antenna-feeder-connection is used as the antenna-feeder-connection-reverse judgment result of the base station to be tested. And if the preset sector direction angle of at least 2 sectors is not matched with the respective actual coverage direction angle range, taking the reverse connection of the at least 2 sectors as the judgment result of the reverse connection of the antenna feed of the base station to be detected. Here, matching means that the preset sector direction angle of the sector is within its actual coverage direction angle range, and mismatching means that the preset sector direction angle of the sector is not within its actual coverage direction angle range.
In the method for judging antenna feeder reverse connection provided by this embodiment, the reporting information of a plurality of user terminals is acquired, where the reporting information indicates the sector and the user position of each user terminal accessing the base station to be detected, so as to realize real-time data acquisition; acquiring the actual coverage direction angle range of each sector according to the reported information, thereby realizing the positioning of the actual direction of the sector; and acquiring the antenna feeder reverse connection judgment result of the base station to be detected according to the preset sector direction angle of each sector and the actual coverage direction angle range of each sector, thereby improving the identification accuracy and the positioning accuracy of the antenna feeder reverse connection problem.
To describe the embodiments of the present invention more clearly, a specific calculation example is illustrated below, which is to implement failure determination of reverse connection between a sector of a base station L2100A and a sector C, for example.
The method comprises the steps of firstly, taking reported information data collected by a base station to be tested on a certain working day, calculating confidence intervals of actual direction angles of three sectors of the base station to be tested, and taking sampling point data of 6 days after 7 months to obtain 5409 sampling position points in total. Wherein, the longitude and latitude of the main sector is O (116.42501,39.86001), and the acquisition cycle spanThe latitude and longitude of a sampling position point in the coverage area of the antenna feeder of the sector are
And i takes a value of 1-5409.
Second, using the position point O (x) of the base station to be measured0,y0) Calculating the longitude and latitude of all sampling position points as the origin
To O (x)0,y0) The direction angle of (c).
Thirdly, checking the quadrant span of the direction angle by using an unbalanced quadrant distribution method, and finding that the sampling position point of the sector A spans the first quadrant and the fourth quadrant (see fig. 4), wherein the sampling proportion in the fourth quadrant exceeds 20%; the sampling position points of the sector B are only distributed in the second quadrant and the third quadrant; the sampling location points of sector C are distributed only in the first quadrant. Therefore, angle conversion is required in the process of calculating the actual coverage direction angle range for the sector a (see the embodiment shown in fig. 4), the actual coverage direction angle range can be directly calculated for both the sector B and the sector C, and the average coverage direction angle of each sector is obtained as follows:
fourthly, calculating the standard deviation of the sample corresponding to each sector based on the average value of the covering direction angles of each sector
The results are as follows:
S(A)＝60°；
S(B)＝34°；
S(C)＝49°。
the fifth step, based on the above sampling distribution theorem formula, the two-sided (1-alpha) confidence interval of the overall mean value mu is the sample mean value
α is 0.05 and Z at a confidence level of 0.95 for 1- αα/2At 1.96, the tolerance is 30 °, and the range of the actual coverage direction angles of the three sectors is as follows:
r1: sector a confidence interval
Degree, the comparison interval (actually covering the direction angle range) is 310 +/-32.5 degrees;
r2: b sector confidence interval
