[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0054] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0055] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0056] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0057] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0058] In the evolution of low-frequency networks, such as 800M and 900M frequency bands, even if they are re-cultivated from long-term evolution (LTE) to new radio (NR), external interference is still severe, especially the external uplink interference problem. The external uplink interference problem has always been an important issue in the process of network deployment and network optimization. This problem directly affects the user experience, for example, it will increase the call drop rate, reduce the success rate of wireless resource control (RRC) establishment, reduce the coverage of base stations, reduce call quality, and lead to a decline in network indicators.

[0059] External uplink interference mainly includes stray interference, interference caused by failure of fixed radio equipment, etc., especially illegal repeaters installed by some users. Due to their low price and poor performance of various components in the equipment, they will cause strong uplink interference. This phenomenon is common in urban villages. External uplink interference is a common problem in low-frequency networks. Therefore, it is necessary to promptly check the interference source and eliminate it. In the process of checking the interference source, a very important step is to correctly measure the direction of the interference source, then find the intersection based on multiple measured interference source directions, and finally lock the location of the interference source.

[0060] At present, the amplitude comparison direction finding method is often used to orient interference sources. The working principle of this method is: in the orientation process, the directional characteristics of the directional antenna array or directional antenna are used to determine the direction of the incoming waves from different directions based on the different signal amplitudes of the electromagnetic waves received by the directional antenna array or directional antenna. The traditional amplitude comparison direction finding method can be divided into the maximum signal method and the minimum signal method according to the different ways of using amplitude information.

[0061] The maximum signal method is to take the direction corresponding to the maximum value of the signal amplitude of the electromagnetic wave received by the direction-finding receiver as the direction of the interference source, that is, the maximum value direction of the antenna pattern as the interference source direction. The advantage of this method is that the equipment required for orientation is simple. However, its disadvantage is that the interference source orientation accuracy is low, because the antenna pattern has a small change rate near the maximum value, that is, when the direction deviates by a large angle, the change in signal amplitude is not obvious.

[0062] The minimum signal method uses the direction with the largest rate of change of the antenna pattern, that is, the direction of the beam null point, for orientation. When the beam null point is aligned with the incoming wave direction, the antenna sensing signal is zero, and the direction-finding receiver output signal is zero. At this time, the beam null point direction is determined to be the incoming wave direction, that is, the interference source direction. In principle, its direction-finding accuracy is high, but in reality, due to the influence of factors such as noise, the output signal of the direction-finding receiver cannot be zero, that is, in actual direction finding, the direction-finding accuracy that can be achieved is low.

[0063] In the actual communication process, the channel is complex and changeable. During the transmission process from the transmitting antenna to the receiving antenna, the signal will experience various complex transmission paths, including direct path, reflection path, diffraction path, scattering path and random combinations of these paths. At the same time, during the propagation of the signal along each path, the effective signal will also be polluted by various noises, such as additive noise and multiplicative noise, resulting in different damages. When the signal is transmitted, there is not only inherent loss due to the transmission path and noise, but also attenuation of the wireless signal power caused by obstructions such as buildings and terrain. This attenuation is not fixed and will change randomly due to the movement of the mobile station and changes in the channel environment. In addition, in actual communication scenarios, there are multiple interference sources at the same frequency point at the same time. In this case, whether the maximum signal method or the minimum signal method is used to direct the interference source, it is difficult to achieve satisfactory accuracy and will produce large errors.

[0064] The interference source orientation method provided by the present application is based on the antenna radiation pattern, and determines the target antenna direction reference pattern that matches the antenna radiation pattern from the antenna direction reference pattern library. It can fully consider the multiple antenna direction reference patterns corresponding to the directions of multiple interference sources, and is closer to the actual situation where electromagnetic waves are received in all directions when there are interference sources. It provides rich reference information for interference source orientation, and determines the direction of the interference source through the target antenna direction reference pattern. It can obtain the actual direction closest to multiple interference sources, avoids the error caused by the single selection of the maximum or minimum value of the signal, and can improve the accuracy of interference source orientation in the case of multiple interference sources.

[0065] The implementation of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0066] Figure 1 The following is a schematic diagram of the architecture of an interference source orientation method provided in an embodiment of the present application. Figure 1 As shown, the architecture includes: a directional receiving antenna 101 and an electronic device 102.

[0067] Among them, the directional receiving antenna 101 can be a Yagi antenna, a parabolic antenna, a horn antenna, a flat antenna, a patch antenna, etc., which is not limited in the embodiment of the present application.

[0068] The directional receiving antenna 101 may be integrated into a direction finding receiver or other devices, which is not limited in the embodiments of the present application.

[0069] In some embodiments, the directional receiving antenna 101 is used to receive electromagnetic waves in various directions of the target cell, and to generate a signal strength sequence based on the signal strength of the received electromagnetic waves.

[0070] The electronic device 102 may be at least one of a mobile phone, a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal, a computer, an independent physical server or a server cluster composed of multiple physical servers, and the embodiments of the present application are not limited to this.

[0071] In some embodiments, the electronic device 102 may be provided with a storage function. For example, the electronic device 102 may store the antenna pattern of the target cell and the antenna direction reference pattern in the antenna direction reference pattern library. By storing the antenna pattern of the target cell and the antenna direction reference pattern library, they can be flexibly used in the subsequent interference source orientation process.

[0072] In some other embodiments, the electronic device 102 may be provided with a computing function. For example, the electronic device 102 determines a target antenna direction reference diagram by processing the antenna direction diagram of the target cell and the antenna direction reference diagram in the antenna direction reference diagram library.

[0073] In an embodiment of the present application, the process of achieving interference source orientation may be: first, the electronic device 102 obtains the antenna pattern of the target cell from the directional receiving antenna 101, such as obtaining a signal strength sequence from the directional receiving antenna 101, and generates the antenna pattern of the target cell based on the signal strength sequence; then, the electronic device 102 determines a target antenna direction reference pattern that matches the antenna pattern from an antenna direction reference pattern library based on the antenna pattern; finally, the electronic device 102 determines the directions of multiple interference sources in the target cell based on the target antenna direction reference pattern.

[0074] The directional receiving antenna 101 and the electronic device 102 are connected via a communication link. The communication link may be a wired communication link or a wireless communication link, which is not limited in the embodiment of the present application.

[0075] In addition, taking the case where the directional receiving antenna 101 is integrated into other devices and the electronic device 102 is a server as an example, the above interference source directional method can be implemented based on an interference source directional system composed of a device with a directional receiving antenna, a direction finding receiver and a server. Figure 2 As shown, Figure 2 A schematic diagram of an interference source directional system provided in an embodiment of the present application.

[0076] The device with a directional receiving antenna is used to collect the signal strength of electromagnetic waves received in all directions within the target cell and transmit the collected signal strength to the direction finding receiver. In addition, the device is also integrated with a turntable and a controller, based on which the directional receiving antenna can be rotated.

[0077] The direction finding receiver is used to output a signal strength sequence of the antenna pattern of the target cell based on the collected signal strength, and send the signal strength sequence to the server.

[0078] The server is used to determine the antenna pattern of the target cell based on the signal strength sequence, and then determine the target antenna direction reference pattern matching the antenna pattern from the antenna direction reference map library based on the antenna pattern, and finally determine the directions of multiple interference sources in the target cell based on the target antenna direction reference map. It can be understood that the server can realize functions such as graphic display and data processing in the interference source orientation process.

[0079] When implemented by hardware, the electronic device may be provided as follows Figure 3 The hardware structure shown, specifically, Figure 3 A schematic diagram of the hardware structure of an electronic device provided in an embodiment of the present application.

[0080] like Figure 3 As shown, the electronic device includes at least one processor 301, a communication line 302, and at least one communication interface 304, and may also include a memory 303. The processor 301, the memory 303 and the communication interface 304 may be connected via the communication line 302.

[0081] The processor 301 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).

[0082] The communication line 302 is used to transmit information between the above components.

[0083] The communication interface 304 is used to communicate with other devices or communication networks, and can use any transceiver-like device, such as Ethernet, radio access network (RAN), wireless local area network (WLAN), etc.

[0084] The memory 303 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 a compressed optical disc, a laser disc, an optical disc, a digital versatile disc, a Blu-ray disc, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to include or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited to these.

[0085] In one possible design, the memory 303 can exist independently of the processor 301, that is, the memory 303 can be a memory outside the processor 301. In this case, the memory 303 can be connected to the processor 301 through the communication line 302, and is used to store execution instructions or application code, and the processor 301 controls the execution to implement the interference source orientation method provided in the following embodiment of the present application. In another possible design, the memory 303 can also be integrated with the processor 301, that is, the memory 303 can be the internal memory of the processor 301, for example, the memory 303 is a high-speed cache, which can be used to temporarily store some data and instruction information.

[0086] As a possible implementation, the processor 301 may include one or more CPUs, for example Figure 3 As another possible implementation, the electronic device may include multiple processors, such as Figure 3 As another possible implementation, the electronic device may further include an output device 305 and an input device 306.

[0087] It should be pointed out that the various embodiments of the present application can learn from or refer to each other. For example, the same or similar steps, method embodiments, system embodiments and device embodiments can all refer to each other without limitation.

[0088] Figure 4 A flowchart of an interference source orientation method provided in an embodiment of the present application, which can be applied to Figure 3 In the electronic device shown. Figure 4 As shown, taking the electronic device as a server as an example, the method includes the following steps:

[0089] S401. The server obtains the antenna pattern of the target cell.

[0090] The antenna pattern of the target cell is a graphical representation of the ability of a directional receiving antenna to receive electromagnetic waves from various directions within the target cell.

[0091] In a possible implementation, the implementation process of step S401 may be:

[0092] Step 1: The server obtains the signal strength of the electromagnetic waves received by the directional receiving antenna in each direction within the target cell.

[0093] Exemplarily, the directional receiving antenna sends a strength message to the server, wherein the strength message includes the signal strength of electromagnetic waves received by the directional receiving antenna in various directions. Correspondingly, the server receives the strength message.

[0094] Step 2: The server determines the antenna pattern of the target cell based on the signal strength of the electromagnetic waves received by the directional receiving antenna in each direction within the target cell.

[0095] In this way, the signal strength of the electromagnetic waves received in various directions is obtained through the directional receiving antenna, thereby determining the antenna pattern of the target cell, which can reflect the actual situation of the target cell as accurately as possible and provide more accurate reference information for subsequent interference source orientation.

[0096] S402: The server determines a target antenna direction reference pattern that matches the antenna direction pattern from an antenna direction reference pattern library based on the antenna direction pattern.

[0097] The antenna direction reference diagram library includes directions of multiple interference sources corresponding to multiple antenna direction reference diagrams, and one antenna direction reference diagram may correspond to directions of multiple interference sources.

[0098] It should be noted that the antenna direction reference diagram library includes multiple antenna direction reference diagrams. The multiple antenna direction reference diagrams include antenna direction reference diagrams of different angles and different numbers of interference sources. For example, the number of different interference sources can be 2, 3, etc., and the different angles can be 30°, 120°, etc.

[0100] In this way, by using multiple antenna direction reference diagrams at different angles and with different numbers of interference sources, and taking into full consideration various situations, the antenna direction reference diagram library can be closer to the actual distribution of interference sources, and provide richer reference information for determining the target antenna direction reference diagram when directing the interference source.

[0101] In a possible implementation, the implementation process of step S402 may be:

[0102] Step 1: Based on the antenna pattern, the server determines the similarity between the antenna pattern and each antenna direction reference pattern in the antenna direction reference pattern library.

[0103] Exemplarily, the server may extract image features from the antenna pattern and each antenna direction reference pattern in the antenna direction reference library through a deep learning algorithm, and determine the similarity based on the extracted image features.

[0104] As another example, the server may determine the similarity based on a signal strength sequence of the antenna pattern and a signal strength sequence of each antenna direction reference pattern in the antenna direction reference pattern library.

[0105] Step 2: Based on the similarity, the server determines a target antenna direction reference pattern that matches the antenna direction pattern.

[0106] In a possible implementation, the server selects, based on the similarities corresponding to the multiple antenna direction reference maps, an antenna direction reference map corresponding to the greatest similarity value from the multiple antenna direction reference maps as the target antenna direction reference map.

[0107] From multiple antenna direction reference maps, the antenna direction reference map corresponding to the largest similarity value is used as the target antenna direction reference map. That is to say, the antenna direction reference map with the highest degree of match with the antenna direction map of the target cell is used as the target antenna direction reference map, so that a more accurate direction of the interference source can be obtained.

[0108] In this way, by determining the target antenna direction reference map through the similarity between the antenna direction map and each antenna direction reference map in the antenna direction reference map library, a situation similar to the actual interference source direction can be obtained, which can improve the accuracy of the interference source orientation.

[0109] S403: The server determines directions of multiple interference sources in the target cell based on the target antenna direction reference map.

[0110] The interference source orientation method provided by the present application is based on the antenna radiation pattern, and determines the target antenna direction reference pattern that matches the antenna radiation pattern from the antenna direction reference pattern library. It can fully consider the multiple antenna direction reference patterns corresponding to the directions of multiple interference sources, and is closer to the actual situation where electromagnetic waves are received in all directions when there are interference sources. It provides rich reference information for interference source orientation, and determines the direction of the interference source through the target antenna direction reference pattern. It can obtain the actual direction closest to multiple interference sources, avoids the error caused by the single selection of the maximum or minimum value of the signal, and can improve the accuracy of interference source orientation in the case of multiple interference sources.

[0111] It should be noted that an antenna direction reference diagram library may be pre-stored in the server, and each antenna direction reference diagram in the antenna direction reference diagram library may be determined based on the following process.

[0112] Considering that in actual situations, the number of interference sources is generally two, the following takes the angle of 90° and the number of interference sources as an example. The process of determining the antenna direction reference diagram can be:

[0113] Step 1: Based on the directional pattern in the specification of the directional receiving antenna, determine the signal strength sequence in the case of a single interference source.

[0114] In a possible implementation, according to different reading accuracies, the signal strength sequence is recorded as f0, f1, ..., fn, where n is the number of reading points.

[0115] For example, with a reading accuracy of 1° and n being 359, the signal intensity sequence can be recorded as f0, f1, ..., f359. Figure 5 A schematic diagram of a directional receiving antenna provided in the specification of the embodiment of the present application. Figure 5 As shown, 0-359 represents the angle value in each direction, and 5, 10, and 15 represent the signal strength values ​​of the electromagnetic waves received by the directional receiving antenna from each direction.

[0116] Step 2: Based on the signal strength sequence of a single interference source, determine the angle to be 90°

[0117] Antenna direction reference diagram when the number of interference sources is 2.

[0118] The angle is the angle between the line connecting the interference source 1 and the sampling point, and the angle between the line connecting the interference source 2 and the sampling point. Figure 6 A schematic diagram of the positional relationship between an interference source and a sampling point provided in an embodiment of the present application. Figure 6 As shown, the angle is 90°, and the interference sources are interference source 1 and interference source 2.

[0119] In a possible implementation, taking a single interference source 1 as an example, the signal strength sequence obtained at the sampling point is f0, f1, ..., f359. Taking a single interference source 2 as an example, the signal strength sequence obtained at the sampling point is f90, f91, ..., f359, f0, f1, f2, ..., f89, and the signal strength sequence corresponding to the interference source 2 is equivalent to the signal strength sequence corresponding to the interference source 1 shifted left by 90 bits.

[0120] The signal strength sequence of the antenna direction reference diagram when the angle is 90° and the number of interference sources is 2 is recorded as F0, F1, ..., F359, where F0=f0+f90, F1=f1+f91, ..., F269=f269+f359, F270=f270+f0, F271=f271+f1, F272=f272+f2, ..., F359=f359+f89, that is, the signal strengths at corresponding positions of the two signal strength sequences are added and summed. Figure 7 A schematic diagram of an antenna direction reference diagram provided in an embodiment of the present application when the angle is 90° and the number of interference sources is 2. Figure 7 As shown, 0-359 represents the angle value in each direction, and 2, 4, 6, 8, and 10 represent the signal strength values ​​of the electromagnetic waves received by the directional receiving antenna from each direction.

[0121] Antenna direction reference diagrams at different angles can be determined based on the above process. For example, within the range of 1° to 180°, an antenna direction reference diagram can be determined every 1°. Similarly, when the number of interference sources is greater than 2, the antenna direction reference diagram can also be determined by the above process.

[0122] It should be noted that each antenna direction reference diagram in the antenna direction reference diagram library does not include noise influence in the determination process. However, the actual antenna direction diagram is affected by noise, so each antenna direction reference diagram is a graphical representation of an ideal situation.

[0123] Figure 8 A flowchart of another interference source orientation method provided in an embodiment of the present application. Figure 8 As shown, taking the interaction between the directional receiving antenna and the server as an example, the method includes the following steps:

[0124] S801. A directional receiving antenna collects signal strengths of electromagnetic waves received in various directions within a target cell.

[0125] In a possible implementation, the directional receiving antenna takes the interference frequency point as the center frequency and starts to measure the signal strength of electromagnetic waves received in all directions in the target cell.

[0126] Exemplarily, firstly, based on the frequency band to be checked, the directional receiving antenna is scanned. Based on the spectrum waveform obtained after the scan, the interference frequency point is obtained. The measurement is performed by manually rotating the directional receiving antenna or rotating the directional receiving antenna through a rotating table.

[0127] It should be noted that when a directional receiving antenna is integrated with a direction finding receiver, its travel speed needs to be kept slow during the measurement process of the directional receiving antenna, so that the position of the direction finding receiver will not change significantly when the directional receiving antenna rotates one circle, or the measurement is performed at a fixed sampling point. In this way, it is possible to avoid large differences in path loss due to large changes in position. By maintaining a slow travel speed, it can be considered that the strength difference of the directional receiving antenna in the measurement is caused by the difference in the receiving gain of the directional receiving antenna.

[0128] In a possible implementation, the directional receiving antenna can be rotated 360° for measurement, and the signal strength of a received electromagnetic wave is collected every 1°. All collected signal strengths are used as a signal strength sequence of the antenna pattern, where each collected signal strength is recorded as a0, a1, ..., a359.

[0129] S802. The directional receiving antenna sends the signal strength of the electromagnetic waves received in each direction in the target cell to the server.

[0130] Correspondingly, the server receives the signal strength.

[0131] S803: The server determines the antenna pattern of the target cell based on the signal strength of the electromagnetic waves received by the directional receiving antenna in various directions in the target cell.

[0132] Fig. 9 A schematic diagram of an antenna pattern of a target cell provided in an embodiment of the present application. Fig. 9 As shown, 0-359 represents the angle values ​​in various directions, and 0.005, 0.01, 0.015, 0.02, and 0.025 represent the signal strength values ​​of electromagnetic waves received by the directional receiving antenna from various directions in the target cell.

[0133] S804: The server obtains a signal strength sequence of the antenna pattern and a signal strength sequence of each antenna direction reference pattern in the antenna direction reference pattern library.

[0134] The signal strength sequence is used to indicate the signal strength of electromagnetic waves received by the directional receiving antenna from various directions.

[0135] It can be understood that there is a one-to-one correspondence between the antenna pattern of the target cell and the signal strength sequence of the antenna pattern, and there is a one-to-one correspondence between the antenna pattern reference pattern and the signal strength sequence of the antenna pattern reference pattern.

[0136] Exemplarily, the server may store antenna patterns and signal strength sequences of antenna patterns, as well as each antenna pattern reference pattern in an antenna pattern reference library and a signal strength sequence of the antenna pattern reference pattern in the form of key-value pairs. The server may obtain the signal strength sequence of the antenna pattern and the signal strength sequence of each antenna pattern reference pattern in the antenna pattern reference library by reading the key-value pairs.

[0137] S805: The server determines the similarity between the antenna pattern and each antenna direction reference pattern in the antenna direction reference pattern library based on the signal strength sequence of the antenna pattern and the signal strength sequence of each antenna direction reference pattern in the antenna direction reference pattern library.

[0138] As a possible embodiment of the present application, the above S805 can also be implemented through the following steps.

[0139] Step 1: For each antenna direction reference graph in the antenna direction reference graph library, the server cyclically shifts the signal strength sequence of the antenna direction graph or the signal strength sequence of the antenna direction reference graph until the signal strength traversal in the corresponding signal strength sequence is completed.

[0140] The cyclic shift may be a cyclic left shift or a cyclic right shift, which is not limited in the embodiments of the present application.

[0141] Step 2: For each cyclic shift, the server determines the similarity between the signal strength sequence of the antenna pattern and the signal strength sequence of the antenna pattern reference pattern based on the signal strength sequence after the cyclic shift.

[0142] Exemplarily, taking the cyclic left shift of the signal strength sequence of the antenna direction reference pattern when the angle is 90° and the number of interference sources is 2 as an example, the signal strength sequence of the antenna direction reference pattern needs to be cyclically shifted 360 times, that is, the similarity between the signal strength sequence of the antenna direction reference pattern and the signal strength sequence of the antenna direction pattern needs to be calculated 360 times.

[0143] It can be understood that the signal strength sequence of the antenna pattern or the signal strength sequence of the antenna pattern reference pattern is cyclically shifted left by i positions, which is equivalent to rotating the antenna pattern or the antenna pattern reference pattern clockwise by i°.

[0144] Step 3: The server uses the similarity with the largest value among the similarities obtained by multiple cyclic shifts as the similarity between the antenna direction pattern and the antenna direction reference pattern.

[0145] Exemplarily, in the similarity between the signal strength sequence of the antenna direction reference diagram when the angle is 90° and the number of interference sources is 2 and the signal strength sequence of the antenna direction diagram, the similarity value when cyclically shifted left by 0 bits is the largest, and the similarity is used as the similarity between the antenna direction reference diagram and the antenna direction diagram when the angle is 90° and the number of interference sources is 2. The similarity is determined based on the following formula (1).

[0146]

[0147] Where A90(0) represents the similarity between the signal strength sequence of the antenna direction reference pattern when the angle is 90° and the number of interference sources is 2 and the signal strength sequence of the antenna direction pattern when the signal strength sequence is cyclically shifted left by 0 bits; F j represents the jth signal strength in the signal strength sequence of the antenna direction reference diagram; a j represents the jth signal strength in the signal strength sequence of the antenna pattern; represents the mean of F0, F1, ..., F359; represents the mean of a1, ..., a359; the value of m is 359.

[0148] In this way, the similarity between the antenna pattern and each antenna direction reference pattern is determined through the signal strength sequence. By simulating the antenna reference patterns at different angles and with different numbers of interference sources, the similarity in various situations can be obtained, thereby improving the accuracy of the interference source direction.

[0149] S806: The server selects, based on the similarities corresponding to the multiple antenna direction reference maps, an antenna direction reference map corresponding to the similarity with the largest value from the multiple antenna direction reference maps as the target antenna direction reference map.

[0150] In this way, from multiple antenna direction reference maps, the antenna direction reference map corresponding to the largest similarity value is selected as the target antenna direction reference map, that is, the antenna direction reference map with the highest degree of matching with the antenna direction map of the target cell is used as the target antenna direction reference map, so that the direction of the interference source is obtained more accurately.

[0151] S807: The server determines directions of multiple interference sources in the target cell based on the target antenna direction reference map.

[0152] Exemplarily, the server stores the angle and number of interference sources corresponding to each antenna direction reference diagram, and the server uses the angle and number of interference sources corresponding to the target antenna direction reference diagram as the angle and number of interference sources of the target cell.

[0153] For example, if the similarity of the target antenna direction reference map is A35(160), the representative angle is 35°, and the antenna direction reference map rotates 160° clockwise, that is, the direction of the corresponding interference source is 160° between the line between the interference source 1 and the sampling point and the preset direction, and the angle between the line between the interference source 2 and the sampling point and the preset direction is 195°. The preset direction may be a geographic direction such as north, or the preset direction may be a direction in which the signal strength of the electromagnetic wave received by the directional receiving antenna is the largest.

[0154] The interference source orientation method provided by the present application is based on the antenna radiation pattern, and determines the target antenna direction reference pattern that matches the antenna radiation pattern from the antenna direction reference pattern library. It can fully consider the multiple antenna direction reference patterns corresponding to the directions of multiple interference sources, and is closer to the actual situation where electromagnetic waves are received in all directions when there are interference sources. It provides rich reference information for interference source orientation, and determines the direction of the interference source through the target antenna direction reference pattern. It can obtain the actual direction closest to multiple interference sources, avoids the error caused by the single selection of the maximum or minimum value of the signal, and can improve the accuracy of interference source orientation in the case of multiple interference sources.

[0155] In the above embodiment, by determining the antenna direction reference diagrams in different directions and with different numbers of interference sources, various situations can be fully taken into account, and rich reference information can be provided for determining the direction of the interference source. The similarity determined based on each antenna direction reference diagram and the antenna direction diagram of the target cell can cover the similarity in various different situations. The antenna direction reference diagram with the highest matching degree is used as the target antenna direction reference diagram, which can be closer to the direction of the actual interference source, improve the accuracy of the interference source orientation, and reduce the orientation error.

[0156] In addition, the above interference source orientation method is also applicable to the situation where a single interference source exists.

For example, each functional module or functional unit can be divided according to each function, or two or more functions can be integrated into one processing module.
