With the rapid development of the wireless communication market, especially the outbreak of data traffic in recent years, the requirements for network coverage and capacity are higher and higher. Therefore, operators invest huge resources, deploy a large number of wireless networks of various systems, the radius of a cell 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 inter-system interference problem becomes more and more serious. For example, China Mobile has the frequency of 1880-1900MHz in the F band, and because the frequency is located at a special position, the F band system has interference with DCS1800, GSM900, PHS and CDMA2000/WCDMA systems; meanwhile, in the existing network, some illegal interferers located in the F frequency band are also provided, and because such interferers cannot distinguish uplink and downlink time slots and transmit interference signals in the full time slot, the interferers can cause obvious interference to the uplink of the base station, and affect the uplink communication quality of all users in the coverage area. In addition, there is another kind of repeater installed privately by users, which often affects the uplink communication of the base station due to poor radio frequency index and too high noise floor.

The defects of the existing solution are mainly concentrated on the second step, the requirement of manual interference elimination on operators is high, the existing network condition is complex, the elimination efficiency is low, and the position of an interference source is not easy to locate.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
Example one
The embodiment of the invention provides an interference positioning method, which is applied to a positioning device and comprises the following steps as shown in figure 1:
step 101: determining at least two detection heights at a measurement position, and detecting an interference signal aiming at least one physical test angle at each detection height of the at least two detection heights to obtain an interference signal detection result of each physical test angle, wherein the interference signal detection result at least comprises the interference signal detected at the physical test angle and direction information thereof;

Here, the positioning apparatus may further include a control unit and a position adjusting unit in addition to the signal detecting unit; the position adjusting unit may include a height adjusting subunit for adjusting a height of the signal detecting unit and an angle adjusting subunit for adjusting a direction of the signal detecting unit.
In the step of controlling the signal detection unit to perform interference signal detection in at least one physical test angle at each of the at least two detection heights, the embodiment does not limit the sequence of each detection height, and the height of the signal detection unit may be adjusted from low to high, or may be adjusted from high to low, or may be set at a medium height first and then set at a highest measurement height and a lowest measurement height respectively.
In addition, the whole set of positioning device can be positioned on a vehicle-mounted platform or a working operation platform. The positioning device has a positioning axis A for fixing the signal detection unit.
Further, the signal detection unit may be an adjustable antenna capable of adjusting the main lobe direction in all directions, such as a 3D electrical tilt antenna. Wherein, just can guarantee to transfer the antenna freely to adjust height and angle in certain extent through adjustment location axle A.
The latitude and longitude information of the positioning axis A can also be reported to the control unit. The radio frequency baseband processing unit is used for weighting the 3D-MIMO antenna to achieve the purpose of different wave beams, and simultaneously can perform preliminary analysis processing on the collected radio frequency signals. The control unit may be a PC that functions to perform the entire operational flow.
The measurement position may be a position set according to an actual situation, for example, when a manager receives a poor mobile phone signal received at a certain area reported by a user, it may be preliminarily determined that an interference source that transmits an interference signal may exist in the area, so that any one position may be selected as the measurement position in the area. According to the experience of the administrator, if an interference source may occur in some areas, a position may be selected from the areas as a measurement position, for example, referring to fig. 2, a report that a received signal is poor is received in area a by 3 user equipments UEs, and the administrator excludes the area from the fact that the quality of the received signal of the UE is poor due to the poor signal of the base station through analysis, and then the administrator may consider that the interference source may exist in area a, and then may select a position of a certain UE in area a as a measurement position 1, or may select a measurement position 2 at will for measurement.
The at least two detection heights may include three detection heights, for example, referring to fig. 3, the three detection heights may be respectively denoted as a measurement height one, a measurement height two, and a measurement height three; wherein, the first measuring height is the lowest, and the third measuring height is the highest.
It should be noted that, the vertical distance between two adjacent measurement heights in the at least two measurement heights may be equal or different; as long as the actual value of each measured height can be directly obtained.
The detecting interference signals for at least one physical test angle comprises:
and respectively carrying out interference signal detection on the target interference frequency band aiming at each physical detection angle in the at least one physical detection angle.
For example, when an area receiving interference provides service for a certain operator, the target interference frequency band may provide the frequency band of the service for the operator, and as shown in fig. 4, it may be determined that the target area is a frequency band corresponding to uplink and downlink of the F frequency band, and specifically, the frequency band of 1880-1900Hz is the target interference frequency band.
The at least one physical detection angle may be at least one physical detection angle on the same horizontal plane, and specifically, the at least one physical detection angle is set according to a direction area that the signal detection unit can cover, for example, when the direction that the signal detection unit can cover is-60 ° to 60 ° of the horizontal direction, that is, the horizontal direction that the signal detection unit covers is 120 degrees, 360 degrees in the horizontal plane may be divided into three parts, which are separated from each other by 120 degrees. That is, assuming that the first physical detection angle is 0 degree, the second physical detection angle is 120 degrees in direction, and the third physical detection angle is 240 degrees in direction, which ensures that all signals in one horizontal plane can be detected. It should be understood that the above is only an example, and when the angle of the horizontal direction that can be covered by the signal detection unit is 60 degrees, 6 physical detection angles need to be set so that the signal detection unit can detect all interference signals in one horizontal plane, which is not exhaustive in the present embodiment.
The detecting of the interference signal in the target interference frequency band includes: controlling the signal detection unit to detect the interference signal of a target interference frequency band within a coverage range; wherein, the coverage area has a horizontal detection range and a vertical detection range.
The coverage range may be set according to the coverage range that can be detected by the signal detection unit, and may be, for example, -60 ° to 60 ° in the horizontal direction and-45 ° to 15 ° in the vertical direction.
Specifically, the controlling the signal detection unit to perform interference signal detection at least one physical test angle to obtain an interference signal detection result at each physical test angle includes: adjusting a main lobe direction of the signal detection unit so that the main lobe direction of the signal detection unit scans and detects a coverage area to obtain an interference signal with the maximum intensity detected in the coverage area; and taking the main lobe direction corresponding to the detected interference signal with the maximum intensity as the direction information of the interference signal.
The scanning detection coverage range can be a horizontal angle which is selected one by one according to a preset stepping value, the horizontal angle is fixed, and a vertical angle range which can be covered by the scanning detection coverage range is scanned under the horizontal angle; or selecting vertical angles one by one according to a preset stepping value, fixing the vertical angles and scanning interference signals in all horizontal angle ranges which can be covered by the scanning device under the selected vertical angles.
The manner of adjusting the direction of the main lobe may be adjusted by a control unit, and a specific manner is not limited in this embodiment.
The interference signal detection result for each physical test angle may be obtained by obtaining all interference signals detected in the physical test angle, and then selecting one interference signal with the maximum strength and the direction information of the main lobe corresponding to the interference signal from all the detected interference signals as the interference signal detection result.
Determining a location area where an interference source corresponding to the measurement location is located based on at least the maximum interference signal corresponding to each detection height and the direction information thereof, which may include:
determining a projection point of the maximum interference signal of each detection height on a target plane based on the maximum interference signal corresponding to each detection height and the direction information thereof; determining a target area by utilizing the projection point of each maximum interference signal on the target plane, and taking longitude and latitude information corresponding to the target area as a position area where an interference source is located.
Wherein the target plane may be a ground plane. Accordingly, referring to fig. 5, assuming that there are three detected altitudes, direction information of the maximum interference signal corresponding to each detected altitude is directions 51, 52, and 53, it can be seen from fig. 5 that extending these directions can have intersection points, i.e. projection points, 510, 520, and 530 with the target plane, i.e. the ground plane, respectively, and these three projection points can form a target area, and longitude and latitude information of these three projection points can be used as the location area of the interference source.
The three detection scenes are only examples, and in actual processing, there may be more detection heights, for example, four or five detection heights, and accordingly, there may be more than three projection points on the target plane, and the target area can also be determined by the more than three projection points by using the above general processing method, and longitude and latitude information corresponding to the target area is used as the location area where the interference source is located.
After determining the location area where the interference source detected at the measurement location is located, the method further includes:
selecting an updated measurement position based on the position area where the interference source is located, and selecting at least two detection heights again at the measurement position;
and at each detection height of the at least two detection heights, controlling the signal detection unit to perform interference signal detection at least one physical test angle so as to obtain an updated interference source position area corresponding to the measurement position based on the obtained interference signal detection result.
Specifically, after the preliminary determination of the positioning information of the interference signal is completed, since the determined target area is a target area, a more accurate position of the interference signal needs to be further acquired, the positioning device may be moved to an area corresponding to the positioning information, and then a measurement position is selected at will, and the positioning of the interference signal is repeated.
Further, the end determination method of the loop processing may be: and when the area of the position area where the interference source is located is smaller than a preset area threshold value, determining to obtain the final position area where the interference source is located, and ending the processing.
The preset area threshold may be set according to an actual situation, for example, in a wide environment, the preset area threshold may be set to 1 square kilometer; in more complex environments, where more accurate positioning is required, the predetermined area threshold may be set to within 500 square meters.
Therefore, by adopting the scheme, the detection result of the interference signal can be detected at one measurement position based on different detection heights and different physical test angles, the maximum interference signal and the direction information thereof corresponding to each detection height are further determined according to the detection result of the interference signal, and finally, the position area where the interference source is located is determined according to a plurality of detection heights, the maximum interference signal and the direction information thereof. Therefore, the problem of excessive manual intervention in the positioning process of the interference source can be avoided, and the accuracy and the detection efficiency of the position area where the interference source is located are improved.

and step B, setting the physical angle of the 3D electrically-tuned antenna to be 0 degree, and adjusting the radio frequency baseband processing unit to enable the system to work in a disturbed frequency band (the specific frequency band can be).
And step C, setting the main lobe direction of the 3D electrically-tuned antenna through the control unit, sequentially scanning the whole area covered by the 3D electrically-tuned antenna (the horizontal direction is-60 degrees, the vertical direction is-45-15 degrees (the specific angle can be adjusted according to the realization capability of the 3D electrically-tuned antenna)), and finding the lobe direction with the largest interference on the frequency spectrograph.
And D, sequentially adjusting the physical angle of the 3D electric tilt antenna to 120 degrees and 240 degrees, and repeating the step C, so that the lobe direction with the maximum interference at a certain height can be found out.
And E, adjusting the altitude of the positioning axis A to be Height +10 m-Height 2, Height +20 m-Height 3 and the like, repeating the steps B-D, thus obtaining a lobe direction with larger interference at each Height, and obtaining position information (including longitude and latitude and Height) where an interference source can be positioned by using the data and the following method.
And F, shifting the whole set of system to the position obtained in the step E, and repeating the steps A to E, so that the interference source can be gradually approached.
