The memory may be stand alone and be coupled to the processor via a communication line. The memory may also be integrated with the processor.

The access network device 102 is a device located at the access network side of the communication system and having a wireless transceiving function or a chip system that can be provided in the device. Access network devices 102 include, but are not limited to: an Access Point (AP) in a WiFi system, such as a home gateway, a router, a server, a switch, a bridge, etc., an evolved NodeB (eNB), a radio network controller (radio network controller, RNC), a NodeB (NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (e.g., home evolved NodeB, or home NodeB, HNB), a Base Band Unit (BBU), a radio relay node, a radio backhaul node, a transmission point (transmission and reception point, TRP, transmission point, TP), etc., may also be a 5G base station, such as a gNB in a new air interface (new radio, NR) system, or a transmission point (TRP, TP), an antenna panel or a group of base stations in a 5G system (including multiple antenna panels), or may also be a network node constituting a gNB or a transmission point, such as a baseband unit, or a distributed unit (distributed unit), an access network unit (RSU), a RSU with a roadside function (RSU), a RSU, a base station (RSU), etc. The access network device 102 also includes base stations in different networking modes, such as a master enhanced NodeB (MeNB), a secondary eNB (SeNB), or a secondary gNB (SgNB). The access network equipment 102 also includes different types, such as ground base stations, air base stations, satellite base stations, and the like.

The uplink interference positioning device 101 is configured to obtain an interference characteristic parameter of an access network device in a preset area.

The interference characteristic parameters comprise uplink interference signal strength and an uplink interference signal arrival angle on a plurality of unit time-frequency resources.

The uplink interference signal strength is the signal strength of the uplink interference signal on the unit time-frequency resource in the preset period.

The preset period may include a plurality of unit time-frequency resources, where the unit time-frequency resources are communication resources on a unit frequency band corresponding to a unit period in the preset period.

The arrival angle of the uplink interference signal is an included angle between the arrival direction of the uplink interference signal and the normal direction of the antenna of the access network equipment in a unit period within a preset period.

In a possible implementation manner, when the uplink interference positioning device 101 is disposed in the access network device 102, the uplink interference positioning device 101 may acquire the interference characteristic parameter of the access network device 102 through an intra-device link.

When the uplink interference positioning device 101 and the access network device 102 are different electronic devices (for example, the uplink interference positioning device 101 is an independent communication device, or the uplink interference positioning device 101 is disposed in another access network device 102), the uplink interference positioning device 101 may send an interference characteristic parameter request message to the access network device 102 in a preset area. Accordingly, the access network device 102 receives the interference characteristic parameter request message from the uplink interference positioning device 101.

The access network device 102 sends an interference characteristic parameter response message to the uplink interference location device 101. Accordingly, the access network device 10 receives the interference characteristic parameter response message from the access network device 102 within the preset area.

Wherein the interference characteristic parameter response message includes the access network device 102 identification and the interference characteristic parameter.

The uplink interference positioning device 101 is further configured to determine, according to the uplink interference signal strength, a plurality of first access network devices that are subject to uplink interference on the target unit time-frequency resource.

Wherein the target unit time-frequency resource is any one of a plurality of unit time-frequency resources.

Since there is a possibility that the access network device 102 is subject to uplink interference on any one of the plurality of unit time-frequency resources, the uplink interference positioning device 101 may detect any one of the plurality of unit time-frequency resources to perform uplink interference positioning detection more comprehensively.

The uplink interference positioning device 101 is configured to determine a target interference source position according to arrival angles of uplink interference signals of a plurality of first access network devices.

For example, the uplink interference positioning device 101 may select two access network devices 102 from the plurality of first access network devices, and determine directions of uplink interference signals received by the two access network devices 102 according to arrival angles of uplink interference signals of the two access network devices 102, where an intersection point of the two directions is a target interference source position.

It should be noted that, the embodiments of the present application may refer to or refer to each other, for example, the same or similar steps, and the method embodiment, the system embodiment and the device embodiment may refer to each other, which is not limited.

Fig. 2 is a flowchart of an uplink interference positioning method provided in an embodiment of the present application. As shown in fig. 2, the method comprises the steps of:

step 201, an uplink interference positioning device acquires interference characteristic parameters of an access network device in a preset area.

The uplink interference signal strength is the signal strength of the uplink interference signal on the unit time-frequency resource in the preset period. Therefore, the uplink interference signal strength can represent the distribution characteristic of the uplink interference signal on the time-frequency domain.

The arrival angle of the uplink interference signal is an included angle between the arrival direction of the uplink interference signal and the normal direction of the antenna of the access network equipment in a unit period within a preset period. Therefore, the arrival angle of the uplink interference signal can represent the distribution characteristic of the uplink interference signal in the spatial domain.

For example, the access network device may calculate the direction of the corresponding signal source according to the signal wave path difference or phase difference of the uplink interference signal reaching different array elements of the antenna array in the access network device. For specific reference, reference is made to the related art, and details thereof are not described herein.

The preset period is a measurement period of the uplink interference signal. The preset period may include a plurality of unit time-frequency resources, where the unit time-frequency resources are communication resources on a unit frequency band corresponding to a unit period in the preset period.

The preset period, the unit period and the unit frequency band in the present application may be set according to actual situations, which is not limited in the present application.

For example, the duration of the preset period is 10ms, the bandwidth of the preset frequency band is 100MHz, the duration of the unit period is 1ms, and the unit frequency band is 1 physical resource block (physical resource block, PRB), that is, the bandwidth is 180KHz.

At this time, 10 unit periods are included in the preset period, which may be represented by { T1, T2, …, T10 }. The preset frequency band comprises 273 frequency bands. Therefore, the preset period includes 2730 units of time-frequency resources, which can be represented by { R1, R2, …, R2730 }. Wherein, the unit time-frequency resource corresponds to the uplink interference signal intensity one by one.

The preset area is an area continuously covered by signals in the wireless network and can be divided in the wireless network according to preset rules. For example, a preset number of areas covered by access network devices, or a preset coverage area.

The access network equipment in the preset area has overlapped frequency bands on the uplink working frequency.

For example, the uplink operating frequency of the access network device 1 is 3500MHz-3600MHz, and the operating frequency of the access network device 2 is 3500MHz-3700MHz, so that the same uplink operating frequency 3500MHz-3600MHz exists between the access network device 1 and the access network device 2.

In a possible implementation manner, when the uplink interference positioning device is set in a certain access network device, the uplink interference positioning device may acquire, through an internal link of the device, an interference characteristic parameter of the access network device according to a preset period.

When the uplink interference positioning device and the access network device are different electronic devices (for example, the uplink interference positioning device is an independent communication device, or the uplink interference positioning device is arranged in other access network devices), the uplink interference positioning device can send an interference characteristic parameter request message to the access network device in the preset area. Correspondingly, the access network equipment receives the interference characteristic parameter request message from the uplink interference positioning device.

The access network equipment sends an interference characteristic parameter response message to the uplink interference positioning device. Correspondingly, the access network equipment receives an interference characteristic parameter response message from the access network equipment in the preset area.

The interference characteristic parameter response message comprises an access network equipment identifier and an interference characteristic parameter.

In a possible implementation manner, a plurality of access network devices in a preset area can acquire interference characteristic parameters according to a preset period so as to reduce signaling overhead of a system and improve detection efficiency of uplink interference positioning. In another possible implementation manner, the uplink interference positioning device sends interference measurement indication messages to a plurality of access network devices in a preset area as required, wherein the interference measurement indication messages carry information such as a preset period, a unit frequency band and the like and are used for indicating the access network devices to periodically detect uplink interference signals and acquire interference characteristic parameters; after receiving the interference measurement indication message, the access network equipment acquires interference characteristic parameters according to a preset period; according to the scheme, the interference characteristic parameters can be obtained according to actual requirements, and the frequency of detecting interference signals by the access network equipment is reduced, so that the data processing resources of the access network equipment and the space resources occupied by data storage are reduced.

Step 202, the uplink interference positioning device determines a plurality of first access network devices subject to uplink interference on the target unit time-frequency resource according to the uplink interference signal intensity.

In one possible implementation manner, the uplink interference positioning device may calculate an average value of uplink interference signal intensities on the target unit time-frequency resource according to the uplink interference signal intensities on the target unit time-frequency resource in a plurality of preset periods, so as to determine a plurality of first access network devices that are subject to uplink interference according to the average value of uplink interference signal intensities. Therefore, the method and the device can avoid influence caused by sporadic factors and improve the detection stability of uplink interference positioning.

Exemplary, upstreamThe interference positioning device obtains the uplink interference signal intensities { P } on the target unit time-frequency resource within 10 preset periods ₁ ，P ₂ ，…，P ₁₀ Then the average value of the uplink interference signal intensity on the target unit time-frequency resource is

It should be noted that, since there may be an access network device that is subject to uplink interference on any one of the plurality of unit time-frequency resources, the uplink interference positioning device may detect any one of the plurality of unit time-frequency resources to perform uplink interference positioning detection more comprehensively.

Step 203, the uplink interference positioning device determines the target interference source position according to the arrival angles of the uplink interference signals of the plurality of first access network devices.

It should be noted that, the arrival angle of the uplink interference signal obtained by the uplink interference positioning device is the arrival angle of the uplink interference signal detected by the access network device before the current moment. However, the interference source causing uplink interference may be a fixed device that is not movable, or may be a device that is movable. Therefore, the uplink interference positioning device can determine the predicted value of the arrival angle of the uplink interference signal in the future period according to the acquired arrival angle of the uplink interference signal, so as to predict the direction of the interference source.

In a possible implementation manner, the uplink interference positioning device may predict an arrival angle of an uplink interference signal of the first access network device in a future period through an arrival angle prediction model.

The uplink interference positioning device can perform model training according to a plurality of interference signal arrival angles of the first access network device and unit time periods corresponding to the plurality of interference signal arrival angles, so that a trained arrival angle prediction model is obtained. The plurality of first access network devices are in one-to-one correspondence with the plurality of angle of arrival prediction models. The arrival angle prediction model is used for reflecting the corresponding relation between the arrival angle of the uplink signal of the corresponding first access network device and the unit time period in the preset period. The future period may be the duration of 1 prediction period.

The angle of arrival prediction model may be a bayesian model, an artificial neural network model, a gradient boost decision tree (gradient boosting decision tree, GDBT) model, or the like, for example.

In this way, the uplink interference positioning device in the present application can determine whether the position of the target interference source changes according to the arrival angle of the uplink interference signal detected before the current moment, and predict the uplink interference arrival angle in the future period through the prediction model, update the arrival angle of the uplink interference signal in real time, thereby improving the positioning accuracy of the moving interference source.

In another possible implementation manner, when the variance of the multiple uplink interference arrival angles of the first access network device acquired by the uplink interference positioning device is smaller than a preset threshold, the uplink interference positioning device may use the average value of the multiple uplink interference arrival angles as the uplink interference signal arrival angle of the first access network device in a future period. Based on the scheme, the uplink interference positioning device can reduce the processing resources for calculating the arrival angle, so that the detection efficiency is improved.

As a possible implementation manner, the uplink interference positioning device may select two access network devices from the plurality of first access network devices, and determine directions of uplink interference signals received by the two access network devices according to arrival angles of the uplink interference signals of the two access network devices, where an intersection point of the two directions is a target interference source position.

It should be noted that the uplink interference positioning device may determine one or more target interference source positions in the above manner.

Hereinafter, a procedure for determining a plurality of first access network devices by the uplink interference positioning device will be described.

As a possible embodiment of the present application, in conjunction with fig. 2, as shown in fig. 3, the above step 202 may be implemented by the following steps 301 to 303.

Step 301, the uplink interference positioning device calculates an uplink interference signal intensity average value of the access network device in the preset area on the time-frequency resource corresponding to the target unit in a plurality of preset periods.

Because the target unit time-frequency resource is any one of the unit time-frequency resources, the uplink interference positioning device can calculate the average value of the uplink interference signal strength of the access network device in the preset area on each unit time-frequency resource through step 301. The average value of the uplink interference signal intensity is the average value of the uplink interference signal intensity on the target unit time-frequency resource in a plurality of preset periods.

According to the method and the device, the average value of the uplink interference signal intensity is calculated to avoid the influence on interference positioning caused by sporadic factors, and the detection stability of uplink interference positioning is improved.

Step 302, the uplink interference positioning device determines a plurality of second access network devices meeting a first preset condition from the access network devices in the preset area.

The first preset condition comprises: the average value of the uplink interference signal intensity is larger than a preset interference threshold value. The preset interference threshold may be set according to practical situations, which is not limited in this application.

The higher the average value of the uplink interference signal strength is, the higher the uplink interference degree of the corresponding access network device on the target unit time-frequency resource is. Otherwise, the lower the average value of the uplink interference signal intensity is, the lower the uplink interference degree of the corresponding access network equipment on the target unit time-frequency resource is.

Therefore, the uplink interference positioning device can screen out the second access network equipment with higher uplink interference degree from the access network equipment in the preset area through the preset interference threshold value, so that the position of the interference source causing the uplink interference to the second access network equipment can be determined later.

Step 303, the uplink interference positioning device determines a plurality of first access network devices according to the plurality of second access network devices.

In a possible implementation manner, the uplink interference positioning device may determine the plurality of second access network devices as the plurality of first access network devices.

It should be noted that, through the above step 302, the uplink interference positioning device may determine a plurality of second access network devices that are subject to uplink interference. However, the plurality of second access network devices may be interfered by uplink signals of different interference sources, so the uplink interference positioning device may further determine an association relationship between the plurality of second access network devices to determine a plurality of first access network devices interfered by the same interference source. The relevant schemes are referred to below and will not be described here.

Based on the above technical solution, the uplink interference positioning device in the present application may calculate the uplink interference signal intensity average value of the access network device in the preset area on the corresponding target unit time-frequency resource in a plurality of preset periods, thereby obtaining a plurality of second access network devices with uplink interference signal intensity average values greater than a preset interference threshold, and determine a plurality of first access network devices according to the plurality of second access network devices. In this way, the access network equipment which is interfered by the uplink in the preset area can be determined, and the subsequent positioning detection of the interference source based on the access network equipment which is interfered by the uplink is facilitated.

As a possible embodiment of the present application, in conjunction with fig. 3, as shown in fig. 4, the above step 303 may be implemented by the following steps 401 to 403.

Step 401, the uplink interference positioning device determines a first distance between the reference access network device and each candidate access network device and an uplink interference signal strength average value of each candidate access network device.

Wherein the reference access network device is any one of a plurality of second access network devices. The candidate access network device is an access network device other than the reference access network device of the plurality of second access network devices.

In one possible implementation manner, the reference access network device may be an access network device with the highest average uplink interference signal strength in the plurality of second access network devices.

The higher the average value of the uplink interference signal strength is, the higher the uplink interference degree of the corresponding access network device on the target unit time-frequency resource is. That is, the closer the access network device is to the location of the interferer. Therefore, the uplink interference positioning device can take the access network device with the highest average value of the uplink interference signal intensities in the plurality of second access network devices as the reference access network device, so as to detect whether the plurality of second access network devices are affected by the same interference source. At this point, the distance between the candidate access network device and the reference access network device may be used to reflect the distance between the candidate access network device and the interferer.

For example, the uplink interference positioning device may pre-store the location information of each access network device in the preset area. And the uplink interference positioning device determines a first distance between the reference access network equipment and each candidate access network equipment according to the position information.

Wherein the location information may be represented by latitude and longitude coordinates.

Step 402, the uplink interference positioning device calculates a first association coefficient between the first distance and the average value of the uplink interference signal intensities of the candidate access network devices.

The first association coefficient is used for representing the association degree of the first distance and the uplink interference signal intensity mean value.

For example, the first correlation coefficient may have a value in the interval of [ -1,1]. And when the first association coefficient is greater than 0, the first distance between the reference access network equipment and the candidate access network equipment and the uplink interference signal intensity mean value of the candidate access network equipment are in positive correlation. And when the first association coefficient is smaller than 0, the first distance between the reference access network equipment and the candidate access network equipment and the uplink interference signal intensity mean value of the candidate access network equipment are in a negative correlation relation. And when the first association coefficient is equal to 0, the first distance between the reference access network equipment and the candidate access network equipment and the uplink interference signal strength mean value of the candidate access network equipment are not associated.

The interference detection device may calculate, by a preset algorithm, a first association coefficient between the first distance and the average value of uplink interference signal strengths of the candidate access network devices. The preset algorithm may be a correlation detection algorithm, such as Pearson algorithm, spearman algorithm, kendall algorithm, etc.

For example, the first correlation coefficient satisfies the following equation 1:

wherein r1 is a first association coefficient, n is the number of candidate access network devices, pi is the average value of uplink interference signal intensities of the ith candidate access network device, di is a first distance between the ith candidate access network device and a reference access network device, P0 is the average value of the uplink interference signal intensities of the n candidate access network devices, and D0 is the average value of the first distances between the n candidate access network devices and the reference access network device.

Step 403, the uplink interference positioning device uses the plurality of second access network devices as a plurality of first access network devices when the first association coefficient is smaller than the first association threshold.

Wherein the first association threshold is less than 0 and greater than-1. The first association threshold may be set according to practical situations, which is not limited in this application.

When the first association coefficient is smaller than the first association threshold, it is stated that the first distance between the reference access network device and the candidate access network device and the uplink interference signal intensity mean value of the candidate access network device have a negative correlation relationship. That is, the closer the first distance between the candidate access network device and the reference access network device, the stronger the uplink interference signal strength average of the candidate access network device.

At this time, the smaller the first association coefficient is, the higher the possibility that the candidate access network device and the reference access network device are affected by the same interference source is. Therefore, in the present application, the uplink interference positioning device may determine that the plurality of second access network devices are more likely to be affected by the same interference source when the first association coefficient is smaller than the first association threshold, so that the plurality of second access network devices are used as a plurality of first access network devices.

It should be noted that the interference source may be one electronic device, or may be a plurality of electronic devices located at the same position, which is not limited in this application.

Based on the above technical solution, the uplink interference positioning device in the present application may determine a first distance between a candidate access network device and a reference access network device in a plurality of second access network devices and an uplink interference signal strength average value of the candidate access network device, thereby determining a first association coefficient between the first distance and the uplink interference signal strength average value, and using the plurality of second access network devices as a plurality of first access network devices when the first association coefficient is smaller than a first association threshold. In this way, the uplink interference positioning device may determine, based on the first association coefficient, an association relationship and an association degree between the first distance between the candidate access network device and the reference access network device and the uplink interference suffered by the candidate access network device. Since the farther the interference source is from the same position, the weaker the strength of the uplink interference signal measured by the access network device is, that is, the negative correlation exists between the uplink interference signal and the distance. Therefore, when the first association coefficient is smaller than the first association threshold, the possibility of the interference sources at the same position where the plurality of second access network devices are subjected is high, and the uplink interference positioning device uses the second access network devices as the plurality of first access network devices, so that the positioning detection of the same interference sources through the combination of the plurality of access network devices can be further realized, and the detection effect of uplink interference positioning is improved.

Hereinafter, a procedure of determining the target interference source position by the uplink interference positioning device will be described.

As a possible embodiment of the present application, in conjunction with fig. 2, as shown in fig. 5, the above-mentioned step 203 may be implemented by the following steps 501-503.

Step 501, an uplink interference positioning device determines a direction of an uplink interference signal of each first access network device.

For example, the uplink interference positioning device may determine a ray according to the antenna normal direction of the first access network device and the arrival angle of the uplink interference signal, and use the direction corresponding to the ray as the direction of the uplink interference signal.

Step 502, the uplink interference positioning device performs a first operation for each third access network device to determine a plurality of candidate interference source positions.

Wherein the third access network device is any one of the plurality of first access network devices.

The first operation includes: the uplink interference positioning device takes an intersection point of the direction of the uplink interference signal of the third access network device and the direction of the uplink interference signal of each fourth access network device as a candidate interference source position.

The fourth access network device is any one access network device except the third access network device in the plurality of first access network devices.

It should be noted that, through the above step 502, the uplink interference positioning device in the present application may select two access network devices from the plurality of first access network devices, and use an intersection point of directions of uplink interference signals of the two access network devices as a candidate interference source position. That is, the uplink interference positioning device may combine the access network devices in the plurality of first access network devices two by two to obtain all candidate interference source positions. The candidate interference source position is the position of the potential interference source.

In step 503, the uplink interference positioning device determines a target interference source position according to the multiple candidate interference source positions.

In one possible implementation, the uplink interference positioning device may determine a plurality of candidate interference source positions as the target interference source positions.

It should be noted that, through the above step 502, the uplink interference positioning device may determine the location of the potential interference source. The uplink interference positioning device can further detect a plurality of candidate interference source positions to determine a target interference source position. The relevant schemes are referred to below and will not be described here.

Based on the above technical solution, the uplink interference positioning device in the present application may determine the direction of the uplink interference signal of each first access network device, so as to combine the uplink interference signals of the plurality of first access network devices in pairs, where the directions of the uplink interference signals of any two first access network devices may determine a candidate interference source position, so as to determine the target interference source position according to the determined plurality of candidate interference source positions. In this way, the method and the device can determine the position of the target interference source based on the arrival angles of the uplink interference signals of the access network devices, and improve the detection efficiency of uplink interference positioning.

As a possible embodiment of the present application, in conjunction with fig. 5, as shown in fig. 6, the above-mentioned step 503 may be implemented by the following step 601.

In step 601, the uplink interference positioning device performs a second operation for each candidate interference source position to determine a target interference source position.

Wherein, as shown in fig. 7, the second operation includes the following steps 701-703:

step 701, the uplink interference positioning device determines a second distance between the candidate interference source position and each first access network device and an uplink interference signal strength average value of each first access network device.

For example, the uplink interference positioning device may determine the second distance between the first access network device and the candidate interference source location according to the pre-stored location information of the first access network device and the location information of the candidate interference source determined in the above step 502.

Step 702, the uplink interference positioning device calculates a second association coefficient between the second distance and the uplink interference signal intensity average value of the first access network device.

The second association coefficient is used for representing the association degree of the second distance and the uplink interference signal intensity mean value.

For example, the second correlation coefficient may have a value in the interval of [ -1,1]. And when the second association coefficient is greater than 0, the second distance between the candidate interference source position and the first access network equipment and the uplink interference signal intensity mean value of the first access network equipment are in positive correlation. And when the second association coefficient is smaller than 0, the second distance between the candidate interference source position and the first access network equipment and the uplink interference signal intensity mean value of the first access network equipment are in a negative correlation relation. And when the second association coefficient is equal to 0, the second distance between the candidate interference source position and the first access network equipment and the uplink interference signal intensity mean value of the first access network equipment are not in association relation.

The interference detection device may calculate, by using a preset algorithm, a second association coefficient between the second distance and the average value of the uplink interference signal strength of the first access network device. The preset algorithm may be a correlation detection algorithm, such as Pearson algorithm, spearman algorithm, kendall algorithm, etc.

For example, the first correlation coefficient satisfies the following equation 2:

Wherein r2 is a second association coefficient, n 'is the number of first access network devices, P' i is the average value of the uplink interference signal intensities of the ith first access network device, D 'i is the second distance between the ith first access network device and the candidate interference source position, P'0 is the average value of the uplink interference signal intensities of the n first access network devices, and D '0 is the average value of the second distance between the n' first access network devices and the candidate interference source position.

In step 703, the uplink interference positioning device determines, as the target interference source position, the candidate interference source positions having the second association coefficient smaller than the second association threshold and the average value of the second distances smaller than the preset distance threshold.

Wherein the second association threshold is less than 0 and greater than-1. The second association threshold and the preset distance threshold may be set according to practical situations, which is not limited in this application.

When the second association coefficient is smaller than the second association threshold, it is stated that the second distance between the first access network device and the candidate interference source position has a negative correlation with the uplink interference signal intensity mean value of the first access network device.

That is, the closer the second distance between the first access network device and the candidate interference source location, the stronger the uplink interference signal strength average of the first access network device.

Therefore, the smaller the second association coefficient, the higher the probability that the candidate interference source position is the position of the interference source causing uplink interference to the plurality of first access network devices.

In addition, the smaller the average value of the second distance is, the closer the distance between the plurality of first access network devices and the candidate interference source position is, the higher the uplink interference degree caused by the interference source corresponding to the candidate interference source position to the plurality of first access network devices is, and the higher the probability of becoming the interference source corresponding to the plurality of first access network devices is.

In summary, the uplink interference positioning device may determine the candidate interference source position as the target interference source position when the second association coefficient is smaller than the second association threshold and the average value of the second distance is smaller than the preset distance threshold, thereby improving accuracy of target interference source position detection.

In a possible implementation manner, the uplink interference positioning device may further determine, as the first candidate interference source position, a candidate interference source position in which the second association coefficient in the plurality of candidate interference source positions is smaller than the second association threshold, and the average value of the second distances is smaller than the preset distance threshold, and further determine, as the target interference source position, the first candidate interference source position corresponding to the minimum value of the second association coefficient in the first candidate interference source position or the average value minimum value of the second distances.

Based on the above technical solution, the uplink interference positioning device in the present application may perform a second operation on each candidate interference location to determine the target interference source location. The uplink interference positioning device may determine a second distance between the candidate interference source position and each first access network device, and an uplink interference signal intensity average value of each first access network device, so as to determine a second association coefficient between the second distance and the uplink interference signal intensity average value. When the second association coefficient is smaller than 0, the smaller the second association coefficient, the higher the degree of negative correlation between the second distance and the uplink interference signal intensity mean value is, that is, the higher the probability that the candidate interference source position is the position of the interference source causing uplink interference to the plurality of first access network devices is. In addition, the smaller the average value of the second distance is, the higher the uplink interference degree caused by the interference source corresponding to the candidate interference source position to the plurality of first access network devices is. Therefore, the uplink interference positioning device can further screen the target interference source position from the candidate interference source positions through the mean value of the second distance and the second association threshold value, so that the accuracy of uplink interference positioning is improved.
