Description

An interference source location system and method

technical field

The present invention relates to the technical field of wireless communication, in particular to a system and method for locating an interference source.

Background technique

With the rapid development of wireless communication technologies, especially the rapid development of data services in recent years, the requirements for network coverage and capacity are getting higher and higher. To this end, operators have invested huge sums of money and deployed a large number of wireless networks of various standards, resulting in smaller and smaller cell radii and more and more reuse of antenna resources. In this case, the noise floor of the network continues to rise, and the problem of interference between systems is also becoming more and more serious.

At the same time, there will be some special types of communication equipment in the network, such as jammers, blockers, repeaters, etc. After working for a long time, these devices may deteriorate in quality and cause certain interference to network devices, especially network devices of the TDD system.

Specifically, when there is network interference, there will be a large number of undesired interference signals in the uplink receiving band of the base station, which will affect the quality of the uplink, reduce the user capacity in the coverage area of the base station, and even some strong interference will directly Block the uplink channel, resulting in the inaccessibility or difficulty for users. Therefore, locating the interference source and eliminating system interference is of great significance for ensuring the normal function and performance of the base station.

Specifically, at present, the industry mainly adopts the following two methods to perform interference detection, so as to locate corresponding interference sources:

Method 1: Combining a portable spectrum analyzer with a directional antenna to perform interference detection. Specifically, the operator uses a portable spectrum analyzer to conduct a frequency sweep test in the interfered area, and constantly changes the direction of the directional antenna and the physical location of the directional antenna to determine the corresponding interference source.

Method 2: Use a base station deployed with a smart antenna to perform interference detection. Specifically, the horizontal beam direction angles of the smart antennas of the interfered cell and its neighboring cells can be tested, and the location of the interference source can be determined according to the horizontal beam direction angles of the smart antennas. For example, specifically, according to the interference straight lines corresponding to the horizontal beam direction angles of the smart antennas of the disturbed cell and its neighboring cells, the corresponding intersecting area can be determined, and the intersecting area can be used as the area where the interference source is located.

However, for the first method, since the operator needs to use the spectrum analyzer for on-site testing, it is time-consuming and labor-intensive. Moreover, for higher sites such as light pole stations and tower stations, since operators cannot directly go to the sky to perform frequency sweep tests, but can only perform frequency sweep tests under the base station, there will be problems caused by ground buildings. Or the blocking of plants and the like makes it difficult to test the corresponding interference signal, making the final location of the interference source inaccurate.

For the second method, since the interference source can only be determined according to the intersecting area of the interference straight line corresponding to the horizontal beam direction angle of the smart antenna of the interfered cell and its neighboring cells, that is, in the process of testing the interference source, a one-step The appropriate way to determine the corresponding interference source, resulting in low positioning accuracy of the interference source.

The interference data collection unit 12 can be used to collect interference data of the interfered cell after the space positioning frame 11 arrives at a designated space position;

The interference data processing unit 13 can be used to analyze and process the interference data of the interfered cell collected by the interference data collection unit 12, and calculate the space position to be updated by the space positioning frame 11 in the next step, And send the corresponding position update command to the space positioning frame 11, instructing the space positioning frame 11 to carry the interference data acquisition unit 12 in the interference source positioning system to the spatial position to be updated until the When the interference data of the interfered cell collected by the interference data collection unit 12 determines that the interference degree of the interfered cell is greater than a preset threshold, record the spatial position of the space positioning frame 11 at this time, and record the recorded space The location is used as the location of the interference source of the base station corresponding to the interfered cell.

Optionally, the interfered cell can be determined by:

Determining a base station interfered by an external interference source; using any one or more cells in the coverage area of the base station as the interfered cell; or, according to the interference data of each cell of the base station read from the network management side (specifically, Refers to data such as interference power, interference level), select the cell whose interference data is greater than the set threshold (the threshold can be flexibly adjusted according to the actual situation) as the corresponding interfered cell, and this embodiment of the present invention will not repeat it.

Further, after the interfered cell is determined, the initial horizontal direction angle and the initial vertical downtilt angle of the antenna of the interfered cell can be read from the network management side, and the initial horizontal direction angle and the initial vertical downtilt angle are determined according to the initial horizontal direction angle and the initial vertical downtilt angle. The initial radiation direction of the antenna of the interfered cell. In addition, at this time, data such as the geographic location of the base station of the interfered cell and the height of the antenna of the interfered cell can also be read from the network management side, which will not be described in this embodiment of the present invention.

Further, after determining the initial radiation direction of the antenna of the interfered cell, the geographic location of the base station of the interfered cell, and the height of the antenna of the interfered cell, the interference data processing unit 13 may According to the above data, determine the initial space position that the space positioning frame 11 should reach, and instruct the space positioning frame 11 to carry the interference source positioning system by issuing a corresponding position update command to the space positioning frame 11 The rest of the units in reach the corresponding initial spatial positions.

Optionally, the set distance from the initial spatial position to the antenna of the interfered cell can be flexibly adjusted according to actual conditions, such as 10 meters from the antenna of the interfered cell, etc., which is not limited in this embodiment of the present invention .

Further, after the space positioning frame 11 arrives at a designated space position, the interference data collection unit 12 can specifically collect the interference data of the interfered cell in the following manner:

Obtain the interference data of the interfered cell when the radiation direction of the antenna of the interfered cell is the initial radiation direction, and acquire the radiation direction of the antenna of the interfered cell based on the initial radiation direction During the adjustment, the interference data of the interfered cell after each antenna adjustment; and the acquired interference data of the interfered cell after each antenna adjustment and the obtained radiation direction of the antenna when The interference data of the interfered cell in the initial radiation direction is taken together as the collected interference data of the interfered cell.

Wherein, the antenna of the interfered cell can adjust the radiation direction in the following manner:

While keeping the vertical downtilt angle of the antenna at the initial vertical downtilt angle, taking the obtained initial horizontal direction angle as a reference, according to the set first adjustment step, respectively in the clockwise and counterclockwise directions adjusting the horizontal direction angle of the antenna to the set first angle adjustment threshold; and, for each possible angle value of the horizontal direction angle of the antenna including the initial horizontal direction angle, while maintaining While the horizontal direction angle of the antenna is the value of each possible angle, taking the acquired initial vertical downtilt angle as a reference, according to the set second adjustment step, respectively upward and downward The vertical downtilt of the antenna is adjusted to the set second angle adjustment threshold;

Alternatively, while keeping the horizontal direction angle of the antenna at the initial horizontal direction angle, taking the obtained initial vertical downtilt angle as a reference, according to the set second adjustment step, respectively upward and downward The vertical downtilt of the antenna is adjusted to the set second angle adjustment threshold; and, for each possible angle value of the vertical downtilt of the antenna including the initial vertical downtilt, while maintaining the set While the vertical downtilt angle of the antenna is the value of each possible angle, taking the obtained initial horizontal direction angle as a reference, according to the set first adjustment step, along the clockwise and counterclockwise directions respectively Adjusting the horizontal direction angle of the antenna to the set first angle adjustment threshold.

Wherein, the value of the first angle adjustment threshold may be 45 degrees to 90 degrees (both end values included), and the value of the second angle adjustment threshold may be 4 degrees to 30 degrees (both end values included). ), and the actual values of the two can also be flexibly adjusted according to the actual situation, and are not limited to the above-mentioned values, which are not limited in this embodiment of the present invention.

Specifically, taking the value of the first angle adjustment threshold as 45 degrees as an example, taking the obtained initial horizontal direction angle as a reference, according to the set first adjustment step, respectively move clockwise and counterclockwise The direction adjusts the horizontal direction angle of the antenna to the set first angle adjustment threshold, which can be specifically implemented as:

The horizontal direction angle of the antenna is based on the initial horizontal direction angle, with a step of 5 degrees (the step can be flexibly adjusted according to the actual situation), and 45 degrees in the clockwise and counterclockwise directions. That is to say, assuming that the initial horizontal angle of the antenna is θ1 degree, adjusted clockwise to "+" and counterclockwise to "-", the angle value of the antenna's horizontal angle can be adjusted to θ1+5 , θ1+10, θ1+15, θ1+20, θ1+25, θ1+30, θ1+35, θ1+40, θ1+45, θ1-5, θ1-10, θ1-15, θ1-20, θ1 -25, θ1-30, θ1-35, θ1-40, θ1-45. If the initial horizontal direction angle θ1 of the antenna before adjustment is added, there are totally 19 possible values of the horizontal direction angle of the antenna.

In addition, it should be noted that, when adjusting the horizontal direction angle of the antenna, a top view of horizontally adjusting the direction of the sky surface may be shown in FIG. 2 , which will not be described in detail in this embodiment of the present invention.

Similarly, taking the value of the second angle adjustment threshold as 30 degrees as an example, taking the obtained initial vertical downtilt angle as a reference, and according to the set second adjustment step, respectively move all the angles up and down. The vertical downtilt angle of the antenna is adjusted to the set second angle adjustment threshold, which can be specifically implemented as:

The vertical downtilt angle of the antenna is based on the initial vertical downtilt angle, with a step of 5 degrees (the step can be flexibly adjusted according to the actual situation), and an upward and downward adjustment of 30 degrees. That is to say, assuming that the initial vertical downtilt angle of the antenna is θ2 degrees, the upward adjustment is "+", and the downward adjustment is "-", then the angle value of the vertical downtilt angle of the antenna can be adjusted to θ2+5, θ2+ 10, θ2+15, θ2+20, θ2+25, θ2+30, θ2-5, θ2-10, θ2-15, θ2-20, θ2-25, θ2-30. If the initial vertical downtilt angle θ2 of the antenna before adjustment is added, there are a total of 13 possible values for the vertical downtilt angle of the antenna.

In addition, it should be noted that a side view of vertically adjusting the sky direction when adjusting the vertical downtilt angle of the antenna may be shown in FIG. 3 , which will not be described in detail in this embodiment of the present invention.

Correspondingly, after adjusting the value of one or more parameters in the horizontal direction angle and vertical downtilt angle of the antenna in the above manner, 13*19-1=246 possible antenna radiation directions ( The initial radiation direction determined by the initial horizontal direction angle and the initial vertical downtilt angle of the antenna is discarded).

Further, whenever the sky surface is adjusted, that is, whenever the antenna radiation direction determined by the two parameters of the antenna's horizontal direction angle and vertical downtilt angle is adjusted to a corresponding set of data different from the initial antenna radiation direction , the interference data (such as interference power, interference level, etc.) of the cell at this time can be obtained according to the adjusted antenna radiation direction (ie, the adjusted actual horizontal angle and actual vertical downtilt angle of the antenna). Optionally, in order to ensure the accuracy of interference data measurement, the measurement duration of each interference data should not be lower than a set duration threshold, such as 1 minute, which is not limited in this embodiment of the present invention.

Further, it should be noted that the interference data acquisition unit 12 may specifically include units such as a directional antenna, a spectrum analyzer, and an uplink synchronization module, so as to obtain corresponding interference data (such as, Uplink interference data); Specifically, for example, through the combination of directional antenna and spectrum analyzer, the spectrum occupancy of the uplink frequency band of the system can be collected to observe whether the uplink spectrum is illegally occupied. If it is illegally occupied, further observe the occupation intensity, so as to obtain to the corresponding uplink interference data.

That is to say, some functions of the interference data acquisition unit 12 described in the embodiment of the present invention can be similar to the existing portable spectrum analyzer and directional antenna used by manual operation, but when using the interference data acquisition unit 12, The interference data collection unit 12 can be automatically loaded to a designated space position by controlling the space positioning frame 11 without manual participation, thereby greatly improving the convenience and efficiency of the interference test.

Further, the interference data processing unit 13 may be set on the ground, and may not move with the movement of the space positioning frame 11, which will not be described in detail in this embodiment of the present invention.

Optionally, the interference data processing unit 13 may be specifically configured to determine whether the interference degree of the interfered cell is greater than a preset threshold according to the interference data of the interfered cell collected by the interference data collecting unit 12, if If not, further combine the antenna radiation direction corresponding to each interference data and the current spatial position of the space positioning frame 11 to calculate the space position to be updated by the space positioning frame 11 in the next step.

Specifically, the interference data processing unit 13 may be configured to determine the largest interference data (or, The average value of the first M groups of interference data sorted in descending order, wherein the M is a natural number not greater than the total number of groups of interference data of the interfered cell collected) whether it is greater than a preset threshold , if yes, it may be determined that the interference degree of the interfered cell is greater than a preset threshold; otherwise, it may be determined that the interference degree of the interfered cell is not greater than a preset threshold. Wherein, the preset threshold can be flexibly set according to actual conditions, which will not be described in detail in this embodiment of the present invention.

Further, when it is determined that the interference degree of the interfered cell is not greater than a preset threshold according to the interference data of the interfered cell collected by the interference data collection unit 12, the interference data processing unit 13 may specifically be used to: From the interference data of the interfered cell collected by the interference data acquisition unit 12, select the first two sets of interference data corresponding to the antenna radiation directions that are consecutive to each other after sorting from large to small (or select according to After sorting from small to large, the corresponding antenna radiation directions of the last two groups are mutually continuous interference data); and, according to the current spatial position of the space positioning frame 11, to set the step (the step can be based on actual conditions Carry out flexible adjustment, such as can be 10m etc.) be that radius draws a sphere, and according to the antenna radiation direction corresponding to the selected two groups of interference data and the drawn sphere, determine the corresponding radiation area; And, determine the The center position of the radiation area is determined, and the center position is used as the space position to be updated by the space positioning frame in the next step.

Specifically, the interference data processing unit 13 can be used to determine the center of the drawn sphere (that is, the current spatial position where the space positioning frame 11 carries the interference data collection unit 12) and the direction according to the endpoint. For the two rays in the radiation direction of the antenna corresponding to the selected two sets of interference data, determine the corresponding radiation area in the drawn sphere, which will not be described in detail in the embodiment of the present invention.

Optionally, the interference data processing unit 13 may be specifically configured to, from the interference data of the interfered cell collected by the interference data collection unit 12, select the top N groups of interference data; and calculate the variance of each two groups of interference data in the selected N groups of interference data, and select the corresponding two groups of interference data with the smallest variance from the selected N groups of interference data, and the smallest variance of the The two sets of interference data are selected as the interference data corresponding to the antenna radiation directions of the first two groups sorted in descending order and are consecutive to each other; wherein, the N is not greater than the collected interference of the interfered cell The natural number of the total number of groups of data.

It should be noted that the selection of two sets of data whose corresponding antenna radiation directions are continuous with each other (such as the corresponding two sets of data with the smallest variance) is mainly to avoid the existence of some interference data with large errors and large values. The finally selected interference data is not accurate; in addition, it should be noted that selecting two sets of interference data can also avoid the problem of inaccurate interference source location caused by selecting only one set of interference data.

Of course, it should be noted that, in addition to selecting the first two sets of interference data that correspond to antenna radiation directions that are consecutive to each other after being sorted in descending order to determine the corresponding radiation area, it is also possible to collect from the interference data Among the interference data of the interfered cell collected by the unit 12, select the largest set of interference data to determine the corresponding radiation area; In the interference data, select the first two sets of interference data sorted from large to small to determine the corresponding radiation area; or, the interference data of the interfered cell collected by the interference data collection unit 12 Among them, the largest set of interference data among the first two sets of interference data with consecutive antenna radiation directions sorted in descending order is selected to determine the corresponding radiation area, which is not limited in this embodiment of the present invention. .

Further, the interference source locating system may also include a data transceiving unit 14:

The data transceiving unit 14 may be configured to forward the interference data collected by the interference data collection unit 12 to the interference data processing unit 13, and forward the location update finger sent by the interference data processing unit 13 to the Space positioning frame 11.
