Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
It should be noted that although functional block diagrams are depicted as block diagrams, and logical sequences are shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the block diagrams in the system. The terms first, second and the like in the description and in the claims and in the above-described figures, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.
First, several nouns referred to in this application are parsed:
interference (Interference): generally, the field of wireless communication is to cause damage to the reception of a useful signal.
Physical cell identity (Physical Cell Identity, PCI) is an important parameter in LTE networks for identifying physical cells between different base stations. Each cell has a unique PCI value that is used to distinguish between different cells to reduce interference and optimize network performance. The PCI value is an integer between 0 and 503, and consists of three parts, namely PSS (Primary Synchronization Signal) ID, SSS (Secondary Synchronization Signal) ID and PCFICH (Physical Control Format Indicator Channel) ID.
The physical resource blocks (Physical Resource Block, PRBs) are the smallest units of physical resources in the LTE system, each PRB containing 12 subcarriers. PRBs are designed to be dynamically allocated to users as needed, thereby providing more efficient spectrum utilization. The PRB interference waveform is a graph showing the distribution of interference signals in the frequency domain. The PRB interference waveform pattern may be used to analyze the characteristics and sources of the interfering signals to help determine the nature and likely cause of the interference. In the PRB interference waveform diagram, information such as the frequency range, intensity, and waveform characteristics of an interference signal is generally displayed.
The network interference discovery sources mainly comprise user site complaints, background network management extracting indexes such as background noise, conversation quality switching and the like, on-line interference serious cells and the like, and background terminals integrate the information to obtain interference cell detail data representing possible network interference. Generally, network interference is generally classified into three types, namely, interference caused by hardware equipment, intra-network interference and external-network interference, wherein the interference caused by the hardware equipment and the internal-network interference are data intra-system interference, and the external-network interference belongs to external-system interference. Referring to fig. 10, when it is found that there is interference in a cell, it is necessary to analyze the interference cell detail data, whether the cell interference belongs to intra-system interference or extra-system interference. For intra-system interference, the system interference can be checked by checking indexes such as parameter configuration of each base station, base station power, overlapping coverage rate of the base stations, MOD3 interference, handover and the like. For off-system interference, the external interference source can be determined by checking on site with a spectrometer and an antenna device. After the interference source is determined in the mode, problem qualification is carried out on the interference source, and then a corresponding interference solution is adopted according to the interference source. In the related art, when the external interference of the system is inspected, the system directly performs inspection and sweep frequency in each cell, the inspection efficiency is low, the period is long, and the interference source cannot be positioned rapidly. The sweep generator antenna adopted during investigation supports multiple frequency bands simultaneously, so that the interference power of the spectrometer is saturated, interference waveform lifting is caused, and the non-interference source can interfere with the waveform to influence the outfield sweep frequency investigation.
Based on this, the embodiment of the application provides a method, a system, electronic equipment and a storage medium for positioning external interference of a communication base station, which aim to improve the positioning accuracy and efficiency of the external interference of the base station.

In an application example of the communication base station external interference positioning method, the communication base station external interference positioning method is applied to a terminal, the terminal communicates with a target frequency band antenna spectrum device in real time, the target frequency band antenna spectrum device can be mounted in movable devices such as a robot or an unmanned aerial vehicle, and the movable devices communicate with the terminal in real time. The terminal can collect signals by controlling the movable equipment to carry the target frequency band antenna frequency spectrum equipment to the appointed place according to the preset control logic, and then analyze and process the signals according to the collected signals so as to determine the position of the external interference source of the base station.

step S102, determining a target investigation region according to interference investigation information by a physical and chemical difference positioning method;
step S103, sweep frequency operation is carried out in a target investigation region by controlling target frequency band antenna frequency spectrum equipment to acquire sweep frequency signals in different directions, wherein the target frequency band antenna frequency spectrum equipment comprises a plurality of signal interfaces, the frequency band range of each signal interface is smaller than a preset range, and the frequency band range comprises an interference frequency band of an interference cell;
step S104, positioning interference sources of the target investigation region according to sweep frequency signals in different directions.
In the steps S101 to S104 illustrated in the embodiments of the present application, by acquiring interference checking information, the interference checking information includes a plurality of interference cells (i.e., coverage areas of interference base stations) in which interference signals exist, an interference frequency band and a location identifier of each interference cell, and then determining a target checking area preliminarily according to the interference checking information by a physical and chemical difference positioning method, so as to improve interference checking efficiency. And then the target frequency band antenna frequency spectrum equipment is controlled to carry out frequency sweep operation in the target investigation region so as to acquire sweep signals in different directions, the adopted target frequency band antenna frequency spectrum equipment comprises a plurality of signal interfaces, the frequency band range of each signal interface is smaller than the preset range and comprises the interference frequency band of an interference cell, the interference source in the target investigation region is positioned according to the sweep signals in different directions, and the interference signals can be rapidly and accurately captured by adopting the antenna acquisition signals comprising the interference frequency band and the frequency band range which are smaller, so that the interference efficiency and accuracy of an external base station are improved.
In step S101 of some embodiments, the interference check information is used to indicate cells that may exist, and the source of the interference check information may be background traffic data statistics, user complaints, and the like. Specifically, the terminal integrates information such as user field complaints, background network management extraction background noise, call quality switching indexes and the like to obtain interference cell detail data representing possible network interference, and after the interference in the system is determined through intra-system interference analysis, the data belonging to the intra-system interference in the interference cell detail data is removed, and the remaining data in the interference cell detail data is processed to obtain interference investigation information. The interference checking information includes a plurality of interference cells in which interference signals may exist, an interference frequency band of each interference cell, a location identifier, an interference strength, a PRB interference waveform diagram, and the like. The location identity of the interfering cell may be identified in the form of a PC I.
In step S102 of some embodiments, the geographic difference positioning method is to utilize a map tool to geographic and present the position and the interference intensity value of the interference cell according to the interference investigation information, preliminarily determine the approximate position area of the interference source, namely the target investigation area according to the coverage direction of the interference cell and the intensity change of the interference intensity value, and then adopt the target frequency band antenna spectrum equipment to carry out field investigation on the target investigation area.
In step S103 of some embodiments, the target frequency band antenna spectrum device is a device including a target frequency band antenna and a spectrum analysis module, where the target frequency band antenna is connected to the spectrum analysis module, and after receiving a signal, the target frequency band antenna transmits the signal to the spectrum analysis module for demodulation and signal analysis. The spectrum analysis module is a spectrometer and can analyze the change of the amplitude, frequency and phase of the signal and present the waveform of the received signal. Referring to fig. 11, the target frequency band antenna in the embodiment of the present application includes a plurality of signal interfaces, for example, the target frequency band antenna is provided with three signal interfaces, and a frequency band range of each signal interface is smaller than a preset range and the frequency band range includes an interference frequency band of an interference cell. Illustratively, the signal interfaces are respectively 1800M interfaces, 2100M interfaces and 800M interfaces, the frequency range of the 1800M interfaces is 1765-1785MHz, the frequency range of the 2100M interfaces is 1920-1940MHz, the frequency range of the 800M interfaces is 825-835MHz, and the frequency range of the signal interfaces does not exceed 20MHz. The performance pair of the target frequency band antenna and the common antenna is as shown in fig. 12, the angle of the horizontal error and the vertical error of the common antenna is larger, the antenna pointing performance is poor, the common antenna only adopts one wide-frequency-band antenna interface, under the base station with a multi-surface antenna or a multi-frequency-band antenna, if the antenna supporting system connected with the spectrometer is wide-frequency band, the spectrometer is easy to saturate under the condition of receiving multiple paths of different signals, interference power lifting is caused, the lifting is not an interference source interference waveform, but is caused by too many supporting frequency bands of the spectrometer antenna, the phenomenon can influence normal frequency sweep, and the target frequency band antenna of the embodiment of the application is provided with a plurality of signal interfaces containing smaller frequency band ranges of interference signal frequencies, and can accurately and pertinently acquire interference signals of a target investigation region through the corresponding signal interfaces to improve the accuracy and efficiency of interference investigation.
In the process of scanning frequency investigation in the target investigation region, investigation operation can be carried out by utilizing a separated angle high point difference positioning method. The method for locating the point difference of the sub-angle is to select the position which is higher than the height of the base station and is free from shielding in the target investigation region, gradually carry out sweep test in sub-angle from the 0 degree direction (the 0 degree direction can be any direction) to determine the direction of the interference source, then continue to adopt the method for locating the point difference of the sub-angle to carry out investigation according to the reduced investigation region of the direction of the interference source, and repeat the step until the position of the interference source is accurately located.
In step S104 of some embodiments, after sweep signals in different directions in the target investigation region are collected through the process of step S103, the direction and the position of the interference source can be determined through signal comparison analysis, if the interference source cannot be found in the target investigation region, the target investigation region can be redetermined by using a three-wire-region positioning method, then the interference source is investigated by using a sub-angle elevation difference positioning method in the target investigation region, and the interference investigation is performed by alternately using the three-wire-region positioning method and the sub-angle elevation difference positioning method, so that the external interference source investigation efficiency of the base station is improved.

Step S201, generating an interference geographic map according to the position identification of the interference cells in the interference investigation information, wherein the coverage area and the interference intensity value of each interference cell are identified on the interference geographic map;
step S202, determining a target investigation region according to the interference intensity value changes of different interference cells on the interference geographic map.
In some embodiments of step S201, latitude and longitude coordinates of an interference cell (i.e. a base station with interference) are queried from a background system according to the location identifier of the interference cell in the interference investigation information, and then interference identification is performed on a universal map according to the queried latitude and longitude coordinates, so as to obtain an interference geographic map. In the interference geographic map, a base station with interference is identified, and the base station with interference is marked with information such as a coverage area (i.e. an interference cell) of the base station, an interference intensity value of an interference signal, an interference frequency and the like.
In some embodiments of step S202, an interference geographic map may be presented to the user through a visual interaction interface, so that the user initially defines a target investigation region on the map according to the change of the interference intensity value marked on the interference geographic map, and feeds back to the terminal. In another example, the terminal may determine a plurality of interference cells with stronger interference signals according to the interference intensity value change of the interference geographic map for the interference cells with the same interference frequency, and determine an area formed by the plurality of interference cells as the target investigation area.
Referring to fig. 3, in some embodiments, the signal interfaces of the target band antenna spectrum device in step S103 may be designed by the following steps:

In this embodiment, the target investigation region may include a plurality of interference cells, and the target interface required to be adopted by the target frequency band antenna spectrum device is determined according to the interference frequency band of the interference cells in the target investigation region, for example, the interference frequency bands of the interference cells included in the target investigation region are 1770-1780MHz, and the target interface is a 1800M signal interface. After the signal interfaces are determined, the target frequency band antenna spectrum equipment is controlled to carry out sweep operation in a target investigation region, and corresponding target interfaces in the target frequency band antenna spectrum equipment are selected to process received signals, so that sweep signals in different directions are obtained.
Referring to fig. 5, in some embodiments, in step S402, the step of controlling the target band antenna spectrum device to perform the sweep operation in the target investigation region may further include, but is not limited to, steps S501 to S502:
step S501, determining a sweep frequency height according to the base station height and the building height in the target investigation region based on the angular altitude difference positioning method, and controlling the position of the target frequency band antenna frequency spectrum equipment at the sweep frequency height, wherein the sweep frequency height is larger than the base station height in the target investigation region and larger than the building height in the target investigation region;
step S502, when the target frequency band antenna spectrum device is located at the position of the sweep frequency height, controlling the target frequency band antenna spectrum device to perform omnibearing sweep frequency at a preset angle interval, wherein the preset angle interval is smaller than the antenna radiation angle of the target frequency band antenna spectrum device.
In some embodiments, a controlled mobile device is taken as an example of a robot, a terminal selects a building with a building top height greater than an interference base station height and a highest building height in a target investigation region as a sweep frequency height according to the base station height and the building height in the target investigation region, so as to reduce the influence of interference signal reflection on signal positioning, then outputs a building position corresponding to the sweep frequency height to enable a robot carrying target frequency band antenna spectrum to move to the building top of the corresponding building, and controls the target frequency band antenna spectrum device to carry out omnibearing sweep frequency at preset angle intervals.
In other embodiments, taking the controlled mobile device as an example of an unmanned aerial vehicle, the terminal determines heights slightly larger than the interference base station height and all building heights in the target investigation region as sweep heights according to the base station height and the building height in the target investigation region, then controls the unmanned aerial vehicle to carry the scanning height position of the target frequency band antenna spectrum device hovering in the target investigation region, and controls the target frequency band antenna spectrum device to conduct omnibearing sweep at preset angle intervals.
When the target frequency band antenna spectrum device performs omnidirectional frequency sweep at a preset angle interval, the preset angle interval is set to be smaller than the antenna radiation angle of the target frequency band antenna spectrum device so as to realize omnidirectional frequency sweep. For example, the antenna radiation angle is 12 degrees, the directional antenna height is lifted as much as possible during the sweep test, the direction starts from the north direction to the 0 degree direction, and the directional interference measurement is performed by taking the 10 degree interval step length.
Referring to fig. 6, in some embodiments, in step S104, the step of locating the interference source of the target investigation region according to the sweep signals in different directions may include, but is not limited to, steps S601 to S604:
Step S601, searching a corresponding physical resource block interference oscillogram from interference investigation information according to the position information of a target investigation region;
step S602, calculating the waveform similarity of a signal waveform diagram of the sweep frequency signal and a physical resource block interference waveform diagram of a target investigation region according to the sweep frequency signal acquired in each direction;

In this embodiment, after a sweep signal is obtained by sweeping with the angular-division high-point difference positioning method, an interference cell included in a target investigation region is searched from interference investigation information according to position information of the region, and a corresponding physical resource block interference waveform diagram is obtained. For the sweep signals collected in each direction, waveform similarity analysis algorithm can be utilized to calculate waveform similarity between a signal waveform diagram of the sweep signals and a physical resource block interference waveform diagram of a target investigation region, when sweep signals with waveform similarity larger than preset similarity exist, the collected signal waveform diagram is considered to be identical to the physical resource block interference waveform diagram monitored by the background, the sweep signals with the similarity larger than the preset similarity are determined to be the interference signals of the target investigation region, then the direction of an interference source is positioned according to the power intensities of the interference signals in a plurality of different directions, different building roof sweep frequency tests are repeatedly conducted by using an angle-division high-point difference positioning method, the direction of the interference source is determined, and finally the position of the interference source is positioned.
It is understood that the waveform similarity analysis algorithm may be a hamming distance algorithm, a pearson correlation coefficient algorithm, a cosine similarity algorithm, or the like. The hamming distance algorithm is used to measure the feature difference between two curves to discern the degree of similarity between the features. The pearson correlation coefficient measures the linear correlation degree between two variables, and the value ranges from-1 to 1, and the closer to 1, the higher the correlation is. Cosine similarity measures the similarity between two vectors by measuring the cosine value of the included angle of the two vectors, the value range is between-1 and 1, and the closer to 1, the higher the similarity is.

In this embodiment, if the positioning method of the angle-division high-point difference cannot position the interference source, that is, when the omnibearing frequency sweep is performed at a certain height position, no frequency sweep signal with the waveform similarity greater than the preset similarity exists, the positioning method further positions the interference source by the three-wire-area positioning method of the interference cells, determines the direction of the interference source by adjusting the azimuth angle of each interference cell, and positions the interference source by reusing the angle-division high-point difference until the interference source is found. The three-line one-area positioning method is to find out the highest direction of the interference intensity value by adjusting the azimuth angle of the base station with the highest interference intensity value, for example, taking 10 degrees as an adjusting step length, recording the azimuth angle, finding out the interference intensity value row name of the second and third interference base stations opposite to the highest direction of the interference intensity value by the same method, finding out the interference maximum direction of the second and third interference base stations by adjusting the azimuth angles of the second and third interference base stations by the same method, recording the azimuth angle, marking the azimuth angle direction after the adjustment of the three interference cells by taking each interference cell as a starting point, re-determining the interference source area by utilizing the three-line one-area positioning method, and carrying out sweep frequency investigation by utilizing the angle-division high point difference positioning method aiming at the area.
According to some embodiments of the present invention, after the position of the suspected interference source is found, closing confirmation is performed, if a plurality of interference powers are reduced or eliminated, the corresponding interference source is determined, otherwise, the suspected antenna feeder is faulty, and the antenna feeder is replaced and then re-monitored. According to the method, the interference investigation information is obtained by analyzing the interference index data, and on the basis of the interference investigation information, the four-step positioning method (namely, the target frequency band antenna filtering spectrometer saturation waveform, the geographic difference positioning method, the angular altitude difference positioning method and the three-line one-area positioning method) is utilized to rapidly position the interference source, the interference source closing verification is carried out, and the correction processing is carried out on the interference source, so that the interference problem is rapidly solved.
