Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for locating an interference source.
Background
With the rapid development of wireless communication technology, especially the rapid development of data services in recent years, the requirements for network coverage and capacity are higher and higher. Therefore, operators invest huge resources and deploy a large number of wireless networks of various systems, so that the cell radius is smaller and smaller, and the reuse situation of the sky resources is more and more. In this case, the network background noise rises continuously, and the problem of interference between systems is becoming more and more serious.
Meanwhile, some special types of communication devices, such as jammers, blockers, repeaters, etc., may exist in the network. After a long time of operation, these devices may have degraded quality, causing some interference to network devices, especially network devices of the TDD system.
Specifically, when there is network interference, a large number of interference signals which are not desired by the user may exist in the uplink receiving band of the base station, so that the quality of the uplink is affected, the user capacity in the coverage area of the base station is reduced, and even some strong interference may directly block the uplink channel, so that the user cannot access or access is difficult. Therefore, positioning the interference source and then eliminating the system interference has important significance for guaranteeing the normal function and performance of the base station.
Specifically, currently, the following two methods are mainly used in the industry to perform interference detection to locate the corresponding interference source:
the first way is to combine the portable spectrometer with a directional antenna for interference detection. Specifically, the operator performs a frequency sweep test in the interfered area by using the portable spectrometer, and determines the corresponding interference source by constantly changing the pointing direction of the directional antenna and the physical position of the directional antenna.
And the second mode is to use the base station distributed with the intelligent antenna to carry out interference detection. Specifically, the horizontal beam direction angle of the smart antenna of the interfered cell and the adjacent cell thereof can be tested, and the position of the interference source is determined according to the horizontal beam direction angle of the smart antenna. For example, specifically, the corresponding intersection area may be determined according to an interference straight line corresponding to a horizontal beam direction angle of the smart antenna of the interfered cell and the neighboring cell thereof, and the intersection area is used as the area where the interference source is located.
However, in the first mode, the field test using a spectrometer is time-consuming and labor-consuming. Moreover, for higher stations such as a lamp post station, a tower station and the like, because the sweep frequency test can not be carried out by directly climbing to the sky surface, but only can be carried out below the base station, the problem that the corresponding interference signal is difficult to test due to the blockage of ground buildings or plants and the like exists, and the final interference source positioning result is inaccurate.
For the second mode, for some lower stations, because the ground environment is complex and the multipath effect is obvious, the direct path is generally difficult to find by only adjusting the horizontal beam direction to select the corresponding interference maximum value, so that misjudgment is easily generated, and the positioning accuracy of the interference source is not high. In addition, for higher stations such as a lamp post station, a tower station and the like, the interference source is directly determined according to the intersection area of the interference straight lines corresponding to the horizontal beam directions of several cells, and the problem that misjudgment is easily caused, so that the positioning area of the interference source is inaccurate is also caused.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
the embodiment of the present invention provides an interference source positioning method, which can be applied to a positioning scenario of an uplink interference source of a base station, and is not limited in the embodiments of the present invention. Specifically, as shown in fig. 1, which is a schematic flow chart of the interference source positioning method according to the first embodiment of the present invention, the interference source positioning method may include the following steps:
step 101: determining an interfered cell of a base station interfered by an external interference source and each adjacent cell of the interfered cell which is interfered similarly.
Optionally, for a base station that is confirmed to be interfered by an external interference source, any one or more cells in the coverage area of the base station can be used as the interfered cells; or, according to the interference data (specifically, data such as interference power, interference level, and the like) of each cell of the base station read from the network management side, a cell with interference data larger than a set threshold (the threshold can be flexibly adjusted according to an actual situation) is selected as a corresponding interfered cell, which is not described in detail in the embodiments of the present invention.
Further, in order to determine each neighboring cell of the interfered cell that is subjected to similar interference, the geographic location of the base station of the current interfered cell may be read from the network management side, and each neighboring cell around the interfered cell may be determined according to the geographic location information, and further each neighboring cell of the interfered cell that is subjected to similar interference may be determined according to the interference data (specifically, data such as interference power, interference level, and the like) of each neighboring cell read from the network management side, for example, a neighboring cell of which the interference data is greater than a set threshold (the threshold may be flexibly adjusted according to an actual situation) is selected as the neighboring cell of the interfered cell that is subjected to similar interference, which is not described in detail herein.
Step 102: and aiming at the interfered cell and each cell in the adjacent cells of the interfered cell, determining the horizontal direction angle and the vertical downward inclination angle of the antenna when the interference of the cell is maximum.
Optionally, for each cell in the interfered cell and the neighboring cells of the interfered cell, the horizontal direction angle and the vertical downtilt angle of the antenna when the cell is interfered most may be determined in the following manner:
determining initial interference data of the cell, an initial horizontal directional angle and an initial vertical downtilt angle of an antenna of the cell; performing angle combination adjustment on the horizontal direction angle and the vertical downward inclination angle of the antenna by taking the obtained initial horizontal direction angle and initial vertical downward inclination angle as references, and obtaining interference data of the cell after each time of the adjustment of the sky surface; selecting front N groups of data which are sequenced from large to small from the acquired interference data of the cell including the initial interference data of the cell, and determining a horizontal direction angle and a vertical downward inclination angle of an antenna when the interference on the cell is the maximum according to a horizontal direction angle and a vertical downward inclination angle of the antenna corresponding to each group of data in the front N groups of data; and N is a natural number which is not more than the total number of the acquired interference data of the cell including the initial interference data of the cell.
Optionally, for the interfered cell and each cell in each neighboring cell of the interfered cell, initial interference data (i.e., data such as interference power and interference level when subsequent antenna angle combination adjustment is not performed yet), an initial horizontal direction angle and an initial vertical downtilt angle of an antenna of the cell (i.e., data such as an antenna horizontal direction angle and a vertical downtilt angle when subsequent antenna angle combination adjustment is not performed yet) of the cell may be read from the network management side, which is not described in detail in the embodiments of the present invention.
Further, for each cell in the interfered cell and each neighboring cell of the interfered cell, performing angle combination adjustment on the horizontal direction angle and the vertical downtilt of the antenna based on the obtained initial horizontal direction angle and initial vertical downtilt of the antenna of the cell, which may include:
while keeping the vertical downtilt angle of the antenna as the initial vertical downtilt angle, respectively adjusting the horizontal direction angle of the antenna to a set first angle adjustment threshold value in clockwise and counterclockwise directions according to a set first adjustment step diameter by taking the obtained initial horizontal direction angle as a reference; and the number of the first and second electrodes,
for each possible angle value of the horizontal direction angle of the antenna including the initial horizontal direction angle, while maintaining the horizontal direction angle of the antenna as the each possible angle value, adjusting the vertical downtilt of the antenna to a set second angle adjustment threshold value respectively upwards and downwards based on the obtained initial vertical downtilt angle and according to a set second adjustment step diameter;
alternatively, the first and second electrodes may be,
respectively adjusting the vertical downward inclination angle of the antenna to a set second angle adjustment threshold upwards and downwards according to a set second adjustment step diameter by taking the obtained initial vertical downward inclination angle as a reference while keeping the horizontal direction angle of the antenna as the initial horizontal direction angle; and the number of the first and second electrodes,
and aiming at each possible angle value of the vertical downward inclination angle of the antenna including the initial vertical downward inclination angle, while the vertical downward inclination angle of the antenna is kept as each possible angle value, the horizontal direction angle of the antenna is adjusted to a set first angle adjustment threshold value respectively along the clockwise direction and the anticlockwise direction by taking the obtained initial horizontal direction angle as a reference according to a set first adjustment step diameter.
The value of the first angle adjustment threshold may be 45 degrees to 90 degrees (including two end values), the value of the second angle adjustment threshold may be 4 degrees to 30 degrees (including two end values), and the actual values of the first angle adjustment threshold and the second angle adjustment threshold may be flexibly adjusted according to actual conditions, and are not limited to the above values, which is not limited in this embodiment of the present invention.
Specifically, taking the value of the first angle adjustment threshold as 90 degrees as an example, taking the obtained initial horizontal direction angle as a reference, and according to a set first adjustment step diameter, adjusting the horizontal direction angle of the antenna to the set first angle adjustment threshold along the clockwise direction and the counterclockwise direction, respectively, may be specifically implemented as:
the horizontal direction angle of the antenna is adjusted by 90 degrees along the clockwise direction and the anticlockwise direction by taking the initial horizontal direction angle as a reference and 10 degrees as a step diameter (the step diameter can be flexibly adjusted according to actual conditions). That is, assuming that the initial horizontal direction angle of the antenna is θ 1 degree, adjusted to "+" clockwise, and adjusted to "-" counterclockwise, the angle value of the horizontal direction angle of the antenna may be adjusted to θ 1+10, θ 1+20, θ 1+30, θ 1+40, θ 1+50, θ 1+60, θ 1+70, θ 1+80, θ 1+90, θ 1-10, θ 1-20, θ 1-30, θ 1-40, θ 1-50, θ 1-60, θ 1-70, θ 1-80, and θ 1-90. If the initial horizontal direction angle θ 1 of the antenna before adjustment is added, the horizontal direction angle of the antenna may take 19 possible values.
In addition, it should be noted that a top view of the horizontal adjustment skyward direction when adjusting the horizontal direction angle of the antenna can be shown in fig. 2, which is not described in detail in the embodiments of the present invention.
Similarly, taking the value of the second angle adjustment threshold as 4 degrees as an example, taking the obtained initial vertical downtilt angle as a reference, and adjusting the vertical downtilt angle of the antenna to the set second angle adjustment threshold respectively upward and downward according to the set second adjustment step diameter, may be specifically implemented as:
the vertical downward inclination angle of the antenna is based on the initial vertical downward inclination angle, and is adjusted by 4 degrees upwards and downwards by taking 1 degree as a step diameter (the step diameter can be flexibly adjusted according to actual conditions). That is, assuming that the initial vertical downtilt angle of the antenna is θ 2 degrees, adjusted to "+" upward, and adjusted to "-", the angle value of the vertical downtilt angle of the antenna may be adjusted to θ 2+1, θ 2+2, θ 2+3, θ 2+4, θ 2-1, θ 2-2, θ 2-3, and θ 2-4. If the initial vertical downtilt angle θ 2 of the antenna before adjustment is added, the vertical downtilt angle of the antenna may take 9 kinds of values in total.
In addition, it should be noted that a side view of the vertical adjustment ceiling direction when adjusting the vertical downtilt of the antenna may be as shown in fig. 3, which is not described in detail in the embodiments of the present invention.
Accordingly, for the angle parameter combination composed of the two parameters of the horizontal direction angle and the vertical downtilt angle of the antenna, after the values of one or more parameters of the horizontal direction angle and the vertical downtilt angle of the antenna are correspondingly adjusted in the above manner, 9 × 19-1 — 170 possibilities can be obtained (initial angle combination data composed of the initial horizontal direction angle and the initial vertical downtilt angle of the antenna are discarded).
Further, after the adjustment of the sky, that is, when an antenna angle parameter combination composed of two parameters, i.e., a horizontal direction angle and a vertical downtilt angle of the antenna, is adjusted to a corresponding set of adjusted angle combination data different from the initial angle combination data, the interference data (e.g., data such as interference power) of the cell at the time may be obtained according to the adjusted angle combination data (i.e., the actual horizontal direction angle and the actual vertical downtilt angle of the adjusted antenna). Optionally, in order to ensure the accuracy of the interference data measurement, the measurement time duration of the cell interference data should not be lower than a set time duration threshold, such as 1 minute, and the like.
Further, in the embodiment of the present invention, after obtaining the interference data of the cell including the initial interference data of the cell, the first N groups of data sorted from large to small (or the last N groups of data sorted from small to large) may be selected from the obtained interference data of the cell including the initial interference data of the cell, so that the horizontal direction angle and the vertical downtilt angle of the antenna when the interference on the cell is the maximum may be determined according to the horizontal direction angle and the vertical downtilt angle of the antenna corresponding to each group of data in the N groups of data subsequently.
Optionally, when N is a natural number (e.g., 3 or 4) not less than 3, determining a horizontal direction angle and a vertical downtilt of an antenna when the cell is most interfered according to the horizontal direction angle and the vertical downtilt of the antenna corresponding to each of the first N groups of data, which may include:
calculating the variance (or standard deviation, etc.) of each two groups of data in the previous N groups of data, selecting two groups of data with the minimum corresponding variance (or standard deviation, etc.) from the previous N groups of data, and determining the horizontal direction angle and the vertical downtilt angle of the antenna corresponding to each group of data in the two groups of data with the minimum variance as the horizontal direction angle and the vertical downtilt angle of the antenna when the interference on the cell is maximum.
It should be noted that, the two groups of data with the smallest variance are selected mainly to avoid the problem that the finally selected interference data is inaccurate due to the existence of some interference data with larger errors and larger values; in addition, it should be noted that selecting two sets of interference data can also avoid the problem that the positioning of the interference source is not very accurate due to selecting only one set of interference data.
Of course, it should be noted that, in order to improve the efficiency of subsequently searching for the interference source, at this time, according to the horizontal direction angle and the vertical downtilt angle of the antenna corresponding to each group of data in the previous N groups of data, determining the horizontal direction angle and the vertical downtilt angle of the antenna when the interference on the cell is the maximum, may further include:
and selecting the largest group of data in the two groups of data with the smallest variance from the front N groups of data, and determining the horizontal direction angle and the vertical downtilt angle of the antenna corresponding to the largest group of data as the horizontal direction angle and the vertical downtilt angle of the antenna when the interference on the cell is the largest.
Further, in the embodiment of the present invention, N may also be a natural number smaller than 3, and accordingly, determining the horizontal direction angle and the vertical downtilt of the antenna when the cell is most interfered according to the horizontal direction angle and the vertical downtilt of the antenna corresponding to each of the N groups of data may include:
when the value of the N is 1, determining the horizontal direction angle and the vertical downtilt angle of the antenna corresponding to the front 1 group of data as the horizontal direction angle and the vertical downtilt angle of the antenna when the interference of the cell is maximum; alternatively, the first and second electrodes may be,
when the value of N is 2, determining the horizontal direction angle and the vertical downtilt angle of the antenna corresponding to the largest group of data in the first 2 groups of data as the horizontal direction angle and the vertical downtilt angle of the antenna when the interference on the cell is the largest, or determining the horizontal direction angle and the vertical downtilt angle of the antenna corresponding to each group of data in the first 2 groups of data as the horizontal direction angle and the vertical downtilt angle of the antenna when the interference on the cell is the largest.
Step 103: and aiming at the interfered cell and each cell in each adjacent cell of the interfered cell, determining a corresponding radiation area according to the geographical position of a base station of the cell, the height of an antenna, and the horizontal direction angle and the vertical downward inclination angle of the antenna when the interference of the cell is maximum.
Optionally, the information such as the geographical position, the antenna height, and the like of the base station of each cell may be read from the network management side, which is not described in detail in the embodiments of the present invention.
Correspondingly, for each cell in the interfered cell and each neighboring cell of the interfered cell, after acquiring the geographic position of the base station of the cell, the height of the antenna, and the horizontal direction angle and the vertical downward inclination angle of the antenna when the cell is interfered most, the corresponding radiation area can be determined on the three-dimensional map according to the data. That is, an antenna radiation line using a point determined by the geographical position of the base station of the cell and the antenna height as a starting point may be constructed according to the antenna radiation direction corresponding to the horizontal direction angle and the vertical downward inclination angle of the antenna when the interference on the cell is the greatest, and then the corresponding radiation area may be determined according to the corresponding antenna radiation line.
Optionally, according to a difference in the number of groups of interference data finally selected from the N groups of data in step 103, the constructed radiation area may be a straight line area corresponding to one radiation line, or may be a triangular area formed by two radiation lines, which is not described in detail in this embodiment of the present invention.
Step 104: and determining the intersection areas of the interfered cell and the radiation areas corresponding to the adjacent cells of the interfered cell, and taking the intersection areas as the positions of the interference sources of the base station.
Optionally, the intersection area of each radiation area may be determined on a map such as a corresponding three-dimensional map according to each radiation area corresponding to the interfered cell and each neighboring cell of the interfered cell.
In addition, it should be noted that, according to the difference in the number of groups of interference data finally selected from the N groups of data in step 103, the formed intersection region may be a point region where a plurality of straight lines or a plurality of straight lines intersect with the corresponding triangular region, or may be a polygonal region where a plurality of triangular regions intersect, which is not described in detail in the embodiment of the present invention.
In the technical scheme of the embodiment of the invention, aiming at an interfered cell of a base station interfered by an external interference source and each cell in each adjacent cell of the interfered cell, a horizontal direction angle and a vertical downward inclination angle of an antenna at the moment when the interference of the cell is maximum can be obtained, a corresponding radiation area is determined according to the horizontal direction angle and the vertical downward inclination angle of the antenna at the moment when the interference of each cell is maximum, and the intersection area of each radiation area is used as the position of the interference source. Generally, the position of each cell antenna is high, and the horizontal radiation direction and the vertical radiation direction of the antenna are considered when the interference source is positioned, so that the antenna can be accurately positioned in a narrow area, and the accuracy of positioning the interference source is improved.
