[0043] Glossary

[0044] 1. Three-point positioning interference source method

[0045] The three-point interference source positioning method includes: selecting a test point, finding the interference signal direction, drawing a direction line, and determining the intersection point.

[0046] First, you need to select at least three test points with known locations. These test points usually need to be at a sufficient height and clear view to accurately receive the interference signal and measure its arrival angle. These test points can be high-rise buildings, mountain tops, towers, or other high-rise locations, or equipment with high sensitivity and directional reception capabilities (such as directional antennas, direction finders, etc.).

[0047] At each test point, use a direction-finding device (such as a Yagi antenna, direction finder, etc.) to find the direction of the interference signal. The direction-finding device measures the direction angle of the interference signal reaching the test point, that is, the direction in which the signal is the strongest or most stable. This direction angle can be obtained through the reading on the device or the display on the software interface.

[0048] According to the interference signal direction angle measured at each test point, draw the corresponding direction lines on the map. These direction lines represent the rays from the test point to the location of the interference source. Usually, we can use map software or drawing tools to draw these direction lines to ensure their accuracy and clarity.

[0049] Finally, observe the direction lines drawn on the map and find their intersection point. This intersection point is the estimated value of the location of the interference source. Due to the possible errors and uncertainties in the actual measurement, the intersection point may not be a precise point, but an area or range. However, by increasing the number of test points and optimizing the direction finding technology, we can gradually narrow this range and improve the accuracy of positioning.

[0050] The above is the explanation of the terms.

[0051] In the process of 800M and 900M network evolution, external uplink interference has always been an important issue in network deployment and optimization. In particular, some illegal repeaters installed by users themselves contain various devices with poor performance, which will cause serious interference to the network uplink.

[0052] In the related art, technicians select multiple test points and locate the interference source based on the intersection of the extension lines of the signal direction of the interference signal measured at the multiple test points. Since there may be large errors in the actual measurement process, the intersection of the extension lines cannot accurately locate the interference source. Therefore, how to improve the accuracy of interference source positioning is a technical problem that still needs to be solved.

[0053] In order to solve the technical problems existing in the related art, in an embodiment of the present application, an interference source positioning device obtains at least one interference signal data. Since the interference signal data includes the signal strength of the interference signal and the measurement position of the interference signal, the interference source positioning device can construct an interference area (i.e., a suspected area where an interference source exists) with the measurement position of the target interference signal whose signal strength is greater than the first threshold in at least one interference signal data as the center. Further, the interference source positioning device can determine the density of interference points in the interference sub-area of ​​the interference area, and thus determine the target interference area with a better density of interference points based on the density of interference points in the interference sub-area. Compared with the prior art, in which the interference source is positioned by the intersection of the extension lines of the signal direction of the interference signal measured by multiple test points, the embodiment of the present application positions the interference source based on the density of interference points in the interference area, thereby improving the accuracy of locating the interference source.

[0054] Below, combined with the attached Figure 1 An interference source positioning system 10 provided in an embodiment of the present application is described in detail. Figure 1 As shown, the interference source positioning system 10 includes: an interference source positioning device 11 and a terminal device 12.

[0055] Among them, the interference source locating device 11 is configured to: obtain at least one interference signal data; the interference signal data includes the signal direction of the interference signal, the signal strength of the interference signal and the measurement position of the interference signal; construct an interference area with the measurement position of the target interference signal in at least one interference signal data as the center; the signal strength of the target interference signal is greater than the first threshold, and the interference area includes at least one interference sub-area; determine the density of interference points in the interference sub-area; the interference point is determined by the intersection of the signal directions of two different interference signals; based on the density of interference points in the interference sub-area, determine the target interference area.

[0056] The terminal device 12 is configured to send at least one interference signal data to the interference source locating device 11 .

[0057] It should be noted that the present application is that the terminal device 12 is a device with wireless communication function, which can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted. It can also be deployed on the water surface (such as ships, etc.). It can also be deployed in the air (for example, on airplanes, balloons and satellites, etc.). The terminal device is also called a mobile station (MS), a terminal (MT) and a terminal, etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal includes a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, the terminal can be: a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.), a vehicle-mounted device (such as a car, a bicycle, an electric car, an airplane, a ship, a train, a high-speed rail, etc.), a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a smart home device (such as a refrigerator, a TV, an air conditioner, an electric meter, etc.), an intelligent robot, a workshop device, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home, a flying device (such as an intelligent robot, a hot air balloon, a drone, an airplane), etc. In a possible application scenario of the present application, the terminal device 12 is a terminal device that often works on the ground, such as a vehicle-mounted device. In this application, for the sake of convenience, chips deployed in the above-mentioned devices, such as system-on-a-chip (SOC), baseband chips, etc., or other chips with communication functions may also be referred to as terminal devices.

[0058] Optionally, the terminal device 12 may be an embedded communication device or a user's handheld communication device, including a mobile phone, a tablet computer, etc.

[0059] As an example, in the embodiment of the present application, the terminal device 12 can also be a wearable device. Wearable devices can also be called wearable smart devices, which are a general term for wearable devices that use wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also realize powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and independent of smartphones to achieve complete or partial functions, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0060] The embodiment of the present application provides an interference source positioning device, which is used to execute the interference source positioning system provided in the embodiment of the present application. Figure 2 This is a schematic diagram of the structure of an interference source positioning device provided in an embodiment of the present application. Figure 2 As shown, the interference source locating device 200 includes at least one processor 201, a communication line 202, and at least one communication interface 204, and may also include a memory 203. The processor 201, the memory 203 and the communication interface 204 may be connected via the communication line 202.

[0061] The processor 201 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present application, such as one or more digital signal processors (DSP), or one or more field programmable gate arrays (FPGA).

[0062] The communication link 202 may include a pathway for transmitting information between the above-mentioned components.

[0063] The communication interface 204 is used to communicate with other devices or communication networks, and can use any transceiver-like device, such as Ethernet, radio access network (RAN), WLAN, etc.

[0064] The memory 203 may be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, an optical disc storage (including compressed optical discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to include or store the desired program code in the form of instructions or data structures and can be accessed by a determining machine, but is not limited to these.

[0065] In one possible design, the memory 203 can exist independently of the processor 201, that is, the memory 203 can be a memory outside the processor 201. In this case, the memory 203 can be connected to the processor 201 through the communication line 202, and is used to store execution instructions or application code, and the processor 201 controls the execution to implement the interference source location method provided in the following embodiment of the present application. In another possible design, the memory 203 can also be integrated with the processor 201, that is, the memory 203 can be the internal memory of the processor 201, for example, the memory 203 is a high-speed cache, which can be used to temporarily store some data and instruction information.

[0066] As an implementation method, the processor 201 may include one or more CPUs, for example Figure 2 As another achievable method, the interference source locating device 200 may include multiple processors, such as Figure 2 As another implementation, the interference source positioning device 200 may further include an output device 205 and an input device 206.

[0067] Below, combined with the attached Figure 3 The interference source positioning method provided in the embodiment of the present application is described in detail. Figure 3 As shown, the interference source positioning method includes S301-S304.

[0068] S301. An interference source locating device obtains at least one interference signal data.

[0069] The interference signal data includes the signal direction of the interference signal, the signal strength of the interference signal and the measurement position of the interference signal.

[0070] In a possible implementation manner, the interference source locating apparatus obtains at least one interference signal data from the terminal device.

[0071] It should be explained that the terminal device can be embedded in the interference source locating device, or can be separately provided outside the interference source locating device, and we do not limit this.

[0072] In another possible implementation, the interference source locating device performs conventional monitoring on the noise floor at the base station side, finds a high-interference cell, and obtains at least one interference signal data in the high-interference cell through a drive test system.

[0073] Optionally, the drive test system includes an automated turntable, directional antenna and spectrum analyzer.

[0074] For example, Figure 4 As shown, the interference source positioning device performs conventional monitoring of the base station side noise floor through a spectrum analyzer to obtain a spectrum diagram, and determines the high-interference cell through the spectrum diagram. The interference source positioning device obtains at least one interference signal data through a drive test system.

[0075] It should be explained that the drive test system selects the frequency band to be checked around the interference cell for scanning, observes the spectrum waveform on the receiver, and selects the interference frequency point. The drive test system takes the interference frequency point as the center frequency and starts the measurement, and then the drive test system obtains the signal strength, the Global Positioning System (GPS) position and the antenna azimuth, and obtains at least one interference signal data.

[0076] Exemplarily, the interference signal data is (P1, A1, R1), where P1 is the measurement position of the interference signal, A1 is the signal direction of the interference signal, and R1 is the signal strength of the interference signal.

[0077] S302: The interference source positioning device constructs an interference area with the measurement position of the target interference signal in at least one interference signal data as the center.

[0078] The signal strength of the target interference signal is greater than a first threshold, and the interference area includes at least one interference sub-area.

[0079] In a possible implementation, the interference source locating device determines a first radius value according to the signal strength of the target interference signal. The interference source locating device constructs an interference area with the measurement position of the target interference signal as the center and the first radius value as the radius.

[0080] Optionally, the first radius value is positively correlated with the signal strength of the target interference signal.

[0081] S303: The interference source positioning device determines the density of interference points in the interference sub-area.

[0082] The interference point is determined by the intersection of the signal directions of two different interference signals.

[0083] In a possible implementation, the interference source locating device inputs the test points corresponding to at least one interference signal data into an electronic map according to a certain ratio. The interference source locating device makes an extension line on the electronic map according to the signal direction of the interference signal in at least one interference signal data, obtains at least one intersection point of the extension line, counts the number of intersection points of the extension line in the interference sub-area, and determines the density of the interference point based on the number of intersection points of the extension line and the area of ​​the interference sub-area.

[0084] In another possible implementation, the interference area is divided into interference sub-areas of equal area, and the density of the interference points is determined based on the number of interference points in the interference sub-areas.

[0085] S304: The interference source locating device determines a target interference area based on the density of interference points in the interference sub-area.

[0086] It needs to be explained that the density of interference points in the target interference area is greater than the threshold.

[0087] The above scheme brings at least the following beneficial effects: In the embodiment of the present application, the interference source positioning device obtains at least one interference signal data. Since the interference signal data includes the signal strength of the interference signal and the measurement position of the interference signal, the interference source positioning device can construct an interference area (i.e., a suspected area where an interference source exists) with the measurement position of the target interference signal whose signal strength is greater than the first threshold in at least one interference signal data as the center. Further, the interference source positioning device can determine the density of interference points in the interference sub-area of ​​the interference area, and thus determine the target interference area with a better density of interference points based on the density of interference points in the interference sub-area. Compared with the prior art, in which the interference source is positioned by the intersection of the extension lines of the signal direction of the interference signal measured by multiple test points, the embodiment of the present application positions the interference source based on the density of interference points in the interference sub-area, thereby improving the accuracy of locating the interference source.

[0088] In one possible implementation, combining Figure 3 ,like Figure 5 As shown, S303, the process in which the interference source locating device determines the density of interference points in the interference sub-area can be specifically implemented through the following S501-S503.

[0089] S501. An interference source positioning apparatus obtains weights corresponding to interference points in an interference sub-area.

[0090] The weight includes the weight of the interference signal strength of the interference point or the weight corresponding to the interference distance of the interference point.

[0091] In a possible implementation manner, the interference source locating device obtains the weights corresponding to the interference points in the interference sub-area from the server.

[0092] S502: The interference source positioning device obtains the number of interference points in the interference sub-region and the area of ​​the interference sub-region.

[0093] In a possible implementation, an extension line is made according to the signal direction of the interference signal in at least one interference signal data to obtain at least one intersection point of the extension line, and the number of intersection points of the extension line in the interference sub-area is counted. The interference source locating device determines the area of ​​the interference sub-area based on the identification information of the interference sub-area.

[0094] S503: The interference source locating apparatus determines the density of interference points in the interference sub-region based on the number of interference points in the interference sub-region, the area of ​​the interference sub-region, and the weights corresponding to the interference points.

[0095] In a possible implementation, if the areas of the interference sub-regions are all the same, the interference source locating device determines the density of the interference points in the interference sub-region based on the product of the number of interference points in the interference sub-region and the weights corresponding to the interference points.

[0096] The above scheme brings at least the following beneficial effects: In the embodiment of the present application, the interference source positioning device determines the density of interference points in the interference sub-region based on the number of interference points in the interference sub-region, the area of ​​the interference sub-region, and the weights corresponding to the interference points. In other words, the interference source positioning device in the embodiment of the present application fully considers the characteristics of the interference points (position characteristics or interference signal strength characteristics), which can improve the accuracy of determining the density of interference points in the interference sub-region.

[0097] In one possible implementation, combining Figure 5 ,like Figure 6 As shown, S503, the interference source locating device determines the density of interference points in the interference sub-region based on the number of interference points in the interference sub-region, the area of ​​the interference sub-region, and the weights corresponding to the interference points, which can be specifically implemented by the following S601-S602.

[0098] S601: An interference source locating apparatus determines the product of the number of interference points in an interference sub-area and the weights corresponding to the interference points to obtain a target product.

[0099] In a possible implementation, the interference source locating device determines the average value of weights corresponding to all interference points in the interference sub-area, determines the product of the number of interference points in the interference sub-area and the average value of weights corresponding to all interference points, and obtains the target product.

[0100] S602: The interference source locating device determines the density of interference points in the interference sub-region according to the ratio of the target product to the area of ​​the interference sub-region.

[0101] In a possible implementation, when the interference sub-areas are all the same, the interference source locating device determines the density of interference points in the interference sub-areas according to the target product.

[0102] The above scheme brings at least the following beneficial effects: in the embodiment of the present application, the interference source locating device determines the density of interference points in the interference sub-region based on the ratio of the target product to the area of ​​the interference sub-region. The interference source locating device not only considers the number of interference points in the interference sub-region but also refers to the area of ​​the interference sub-region, thereby improving the accuracy of determining the density of interference points in the interference sub-region.

[0103] In one possible implementation, combining Figure 5 ,like Figure 7 As shown, S501, the process in which the interference source positioning device obtains the weight corresponding to the interference point in the interference sub-area can be specifically implemented by the following S701-S703.

[0104] S701: An interference source locating apparatus obtains a first interference signal and a second interference signal corresponding to an interference point through a signal direction of the interference signal corresponding to the interference point.

[0105] The signal direction of the first interference signal and the signal direction of the second interference signal are two different interference signals that determine the interference point.

[0106] In a possible implementation, when the weight is the weight of the interference signal strength of the interference point, the interference source locating device obtains the first interference signal and the second interference signal corresponding to the interference point through the signal direction of the interference signal corresponding to the interference point.

[0107] It should be explained that, since the interference point is determined by the intersection of the signal directions of two different interference signals, the interference source locating device obtains the first interference signal and the second interference signal corresponding to the interference point through the signal direction of the interference signal corresponding to the interference point.

[0108] S702: The interference source locating apparatus obtains the signal strength of the first interference signal and the signal strength of the second interference signal.

[0109] In a possible implementation manner, the interference source locating device obtains the signal strength of the first interference signal according to the identification information of the first interference signal, and obtains the signal strength of the second interference signal according to the identification information of the second interference signal.

[0110] S703: The interference source locating apparatus determines a weight of the interference signal strength of the interference point based on the signal strength of the first interference signal and the signal strength of the second interference signal.

[0111] In a possible implementation, the interference source locating device determines the first signal strength interval to which the signal strength of the first interference signal belongs and the second signal strength interval to which the signal strength of the second interference signal belongs, respectively, and generates a signal strength combination based on the first signal strength interval and the second signal strength interval. The interference source locating device determines the weight of the interference signal strength of the interference point based on the information strength combination and the signal strength combination table.

[0112] Optionally, the signal strength combination includes a first signal strength interval and a second signal strength interval; the signal strength combination table includes at least one signal strength combination and a weight corresponding to the signal strength combination.

[0113] Exemplarily, signal strength interval 1 is less than -100dBm, signal strength interval 2 is [-100dBm, -90dBm), signal strength interval 3 is [-90dBm, -80dBm), and signal strength interval 4 is greater than -80dBm. If the signal strength combination includes signal strength interval 1 and signal strength interval 1, the weight of the interference signal strength of the interference point is 0.5; if the signal strength combination includes signal strength interval 1 and signal strength interval 2, the weight of the interference signal strength of the interference point is 0.7; if the signal strength combination includes signal strength interval 1 and signal strength interval 3, the weight of the interference signal strength of the interference point is 0.9; if the signal strength combination includes signal strength interval 1 and signal strength interval 4, the weight of the interference signal strength of the interference point is 1; if the signal strength combination includes signal strength interval 2 and signal strength interval 2, the weight of the interference signal strength of the interference point is 0.8; If the signal strength combination includes signal strength interval 2 and signal strength interval 3, the weight of the interference signal strength of the interference point is 1.2; if the signal strength combination includes signal strength interval 2 and signal strength interval 4, the weight of the interference signal strength of the interference point is 1.4; if the signal strength combination includes signal strength interval 3 and signal strength interval 3, the weight of the interference signal strength of the interference point is 1.6; if the signal strength combination includes signal strength interval 3 and signal strength interval 4, the weight of the interference signal strength of the interference point is 1.8; if the signal strength combination includes signal strength interval 4 and signal strength interval 4, the weight of the interference signal strength of the interference point is 2.

[0114] The above scheme brings at least the following beneficial effects: In the embodiment of the present application, the interference source positioning device determines the first signal strength interval to which the signal strength of the first interference signal belongs and the second signal strength interval to which the signal strength of the second interference signal belongs based on the signal strength of the first interference signal and the signal strength of the second interference signal. Furthermore, the interference source positioning device determines the weight of the interference signal strength of the interference point based on the information strength combination and the signal strength combination table. Since the signal strengths of different interference signals correspond to different signal strength intervals, and different signal interval combinations correspond to the weights of the interference signal strengths of different interference points, the weights of the interference signal strengths of the interference points can be accurately determined.

[0115] In one possible implementation, combining Figure 7 ,like Figure 8 As shown, S703, the process in which the interference source locating device determines the weight of the interference signal strength of the interference point based on the signal strength of the first interference signal and the signal strength of the second interference signal can be specifically implemented by the following S801-S803.

[0116] S801. An interference source locating apparatus determines a first signal strength interval to which a first interference signal belongs and a second signal strength interval to which a second interference signal belongs.

[0117] Exemplarily, the signal strength intervals include: signal strength interval 11 is [-120dBm, -110dBm), signal strength interval 12 is [-110dBm, -100dBm), signal strength interval 13 is [-100dBm, -90dBm), signal strength interval 14 is [-90dBm, -80dBm), and signal strength interval 15 is [-80dBm, MAXdBm).

[0118] It should be explained that MAXdBm is the maximum signal strength value in the drive test area. When MAXdBm is less than -80dBm, signal strength interval 15 does not exist.

[0119] S802: The interference source locating apparatus determines a middle value of a first signal strength interval and a middle value of a second signal strength interval.

[0120] Exemplarily, if the first signal strength interval is signal strength interval 11, the middle value of the first signal strength interval is -115dBm; if the second signal strength interval is signal strength interval 12, the middle value of the second signal strength interval is -105dBm.

[0121] S803: The interference source locating apparatus determines a weight of the interference signal strength of the interference point based on the sum of the middle value of the first signal strength interval and the middle value of the second signal strength interval.

[0122] The sum of the middle value of the first signal strength interval and the middle value of the second signal strength interval is positively correlated with the weight of the interference signal strength of the interference point.

[0123] Exemplarily, if the first signal strength interval is signal strength interval 11 and the second signal strength interval is signal strength interval 11, the sum of the middle value of the first signal strength interval and the middle value of the second signal strength interval is -230dBm, and the interference source locating device determines that the sum of the middle value of the first signal strength interval and the middle value of the second signal strength interval is -230dBm, and the corresponding weight is 0.2.

[0124] The above scheme brings at least the following beneficial effects: In the embodiment of the present application, the interference source locating device determines the first signal strength interval to which the first interference signal belongs and the second signal strength interval to which the second interference signal belongs, and determines the weight of the interference signal strength of the interference point based on the sum of the middle value of the first signal strength interval and the middle value of the second signal strength interval, which can improve the efficiency of the interference source locating device in determining the weight of the interference signal strength of the interference point.

[0125] In one possible implementation, combining Figure 5 ,like Fig. 9 As shown, S501, the process in which the interference source positioning device obtains the weight corresponding to the interference point in the interference sub-area can be specifically implemented by the following S901-S902.

[0126] S901. An interference source locating device obtains a target distance between an interference point and a measurement position of a target interference signal.

[0127] In a possible implementation, when the weight is a weight corresponding to the interference distance of the interference point, the interference source locating device obtains the target distance between the interference point and the measurement position of the target interference signal from the electronic map.

[0128] S902: The interference source positioning device determines a weight corresponding to the interference distance of the interference point based on the target distance.

[0129] In a possible implementation manner, the interference source locating device determines the distance interval to which the target distance belongs, and determines the weight corresponding to the interference distance of the interference point based on the weight corresponding to the distance interval.

[0130] Optionally, the target distance is negatively correlated with the weight corresponding to the interference distance of the interference point.

[0131] In another possible implementation, the interference source positioning device takes the measurement position of the target interference signal as the center, constructs a first circular interference sub-interval in the interference area with a first value as the radius, constructs a second circular interference sub-interval in the interference area with a second value as the radius, and constructs a third circular interference sub-interval in the interference area with a third value as the radius. The first value is greater than the second value, and the second value is greater than the third value. The interference source positioning device determines the circular interference sub-interval to which the target distance belongs, and determines the weight corresponding to the interference distance of the interference point based on the weight corresponding to the circular interference sub-interval.

[0132] For example, the first value is r3, the second value is r2, and the third value is r1. If the target distance is less than r1, the weight corresponding to the interference distance is 5; if the target distance is [r1, r2), the weight corresponding to the interference distance is 2; if the target distance is [r2, r3), the weight corresponding to the interference distance is 1.

[0133] The above scheme brings at least the following beneficial effects: In the embodiment of the present application, since the target distance is negatively correlated with the weight corresponding to the interference distance of the interference point, the interference source locating device determines the weight corresponding to the interference distance of the interference point based on the target distance.

[0134] In one possible implementation, combining Figure 5 ,like Fig.10 As shown, S502, the process in which the interference source locating device obtains the number of interference points in the interference sub-region and the area of ​​the interference sub-region by the interference source locating device obtaining the number of interference points in the interference sub-region can be specifically implemented by the following S1001-S1003.

[0135] S1001. An interference source locating apparatus obtains a third interference signal and a fourth interference signal corresponding to a first interference point in an interference sub-area according to a signal direction of an interference signal corresponding to a first interference point.

[0136] The first interference point is any interference point in the interference sub-area; the signal direction of the third interference signal and the signal direction of the fourth interference signal are two different interference signals that determine the first interference point.

[0137] It should be explained that, since the interference point is determined by the intersection of the signal directions of two different interference signals, the interference source locating device obtains the third interference signal and the fourth interference signal corresponding to the interference point through the signal direction of the interference signal corresponding to the first interference point.

[0138] S1002: If the measurement positions of the third interference signal and the fourth interference signal are both in the interference area, the interference source locating apparatus determines the first interference point as a valid interference point in the interference sub-area.

[0139] It needs to be explained that if the measurement position of the third interference signal and the measurement position of the fourth interference signal are both in the interference area, then the third interference signal and the fourth interference signal are interference signals belonging to the same interference source. Only two interference signals belonging to the same interference source can determine the interference source, that is, the first interference point is the effective interference point in the interference sub-area.

[0140] S1003: The interference source locating apparatus determines the number of interference points in the interference sub-area based on the number of effective interference points in the interference sub-area.

[0141] In a possible implementation, if the measurement position of the third interference signal and / or the measurement position of the fourth interference signal are both in the non-interference area, the interference source locating device determines that the first interference point is an invalid interference point in the interference sub-area. The interference source locating device ignores the number of invalid interference points and takes the number of valid interference points in the interference sub-area as the number of interference points in the interference sub-area.

[0142] It should be explained that the interference source locating device obtains the fifth interference signal based on the measurement position of the interference signal, and the measurement position of the fifth interference signal is in the second interference area outside the interference area. The interference source locating device selects the fifth target interference signal from the fifth interference signal, and constructs the second interference area with the measurement position of the fifth target interference signal as the center. The interference source locating device determines the density of interference points in the interference sub-area of ​​the second interference area, and determines the interference source in the second interference area based on the density of interference points in the interference sub-area of ​​the second interference area.

[0143] The above scheme brings at least the following beneficial effects: In the embodiment of the present application, the interference source locating device determines whether the first interference point is a valid interference point based on the positions of the third interference signal and the fourth interference signal corresponding to the first interference point, which can improve the accuracy of determining the interference point density of the interference sub-area.
