Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a physical address update method, apparatus and storage medium. Background Technology

[0002] In mobile communication networks, the addresses of wireless network elements can include logical addresses and physical addresses. The logical address identifies the address used by the wireless network element in the program, while the physical address identifies the actual address of the wireless network element; both are crucial in practical operation. Logical addresses are unique and immutable, while physical addresses may change. If the physical address of a wireless network element changes and is not updated, it can lead to inaccurate or incorrect device location identification. Therefore, in practice, when the physical address of a wireless network element changes, it needs to be updated to avoid inaccurate or incorrect location identification. Currently, the method for updating the physical address of a wireless network element can be as follows: based on the physical address of each wireless network element, determine the distance between each wireless network element, and assign at least one wireless network element within a preset distance range as a physical address.

[0003] However, due to the large number of wireless network elements, updating their physical addresses using the above method involves a significant amount of computation, resulting in low efficiency. Furthermore, the physical addresses of wireless network elements are prone to change, leading to poor stability in the updated addresses. Given this instability, the above method needs to be repeatedly executed to ensure the updated addresses have strong stability and reference value. This significantly increases the computational load, further reducing the efficiency of updating physical addresses. Summary of the Invention

[0004] This application provides a physical address updating method, apparatus, and storage medium, which can improve efficiency in the process of updating the physical address of wireless network elements.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a physical address update method, which includes: obtaining the initial physical addresses of multiple first wireless network elements and multiple towers within a target area; clustering the multiple first wireless network elements and multiple towers according to the initial physical addresses of the multiple first wireless network elements and the multiple towers to obtain at least one cluster; if the target cluster includes at least one tower, updating the initial physical address of each first wireless network element in the target cluster based on the physical address of at least one tower to obtain the updated physical address of each first wireless network element in the target cluster; the target cluster is any one of the at least one clusters.

[0008] In one possible implementation, the method further includes: obtaining the current physical address of a second wireless network element within the target area; the second wireless network element includes at least one of the following: a first wireless network element whose initial physical address has changed among a plurality of first wireless network elements, and a newly added wireless network element other than the plurality of first wireless network elements within the target area; determining the similarity between the current physical address of the second wireless network element and at least one cluster based on a classification algorithm and the current physical address of the second wireless network element; and determining the updated physical address of any first wireless network element in the cluster with the highest similarity as the updated physical address of the second wireless network element.

[0009] In one possible implementation, determining the updated physical address of any first wireless network element in the cluster with the highest similarity as the updated physical address of the second wireless network element includes: determining the distance between the second wireless network element and each first wireless network element in the cluster with the highest similarity based on the updated physical address of the second wireless network element and the updated physical addresses of each first wireless network element in the cluster with the highest similarity; determining the number of third wireless network elements in the cluster with the highest similarity based on the distance between the second wireless network element and each first wireless network element in the cluster with the highest similarity; the third wireless network element is a first wireless network element whose distance is less than a first preset threshold; if the number of third wireless network elements is greater than a second preset threshold, determining the updated physical address of any first wireless network element in the cluster with the highest similarity as the updated physical address of the second wireless network element.

[0010] Secondly, this application provides a physical address updating device, which includes: a communication unit and a processing unit; the communication unit is used to acquire the initial physical addresses of a plurality of first wireless network elements and the physical addresses of a plurality of towers within a target area; the processing unit is used to cluster the plurality of first wireless network elements and the plurality of towers according to the initial physical addresses of the plurality of first wireless network elements and the physical addresses of the plurality of towers to obtain at least one cluster; when the target cluster includes at least one tower, the processing unit is further used to update the initial physical addresses of each first wireless network element in the target cluster based on the physical addresses of at least one tower to obtain the updated physical addresses of each first wireless network element in the target cluster; the target cluster is any one of the at least one cluster.

[0011] In one possible implementation, when the target cluster does not include towers, the processing unit is further configured to determine at least one set based on the initial physical addresses of each first wireless network element in the target cluster; the initial physical addresses of each first wireless network element included in a set are the same, and the initial physical addresses of the first wireless network elements in different sets are different; the processing unit is further configured to count the number of first wireless network elements in each set in the at least one set; the processing unit is further configured to determine the initial physical address of any first wireless network element in the set with the largest number of first wireless network elements as the updated physical address of each first wireless network element in the target cluster.

[0012] In one possible implementation, the communication unit is further configured to obtain the current physical address of a second wireless network element within the target area; the second wireless network element includes at least one of the following: a first wireless network element whose initial physical address has changed among a plurality of first wireless network elements, and a newly added wireless network element other than the plurality of first wireless network elements within the target area; the processing unit is further configured to determine the similarity between the current physical address of the second wireless network element and at least one cluster based on a classification algorithm and the current physical address of the second wireless network element; the processing unit is further configured to determine the updated physical address of any first wireless network element in the cluster with the highest similarity as the updated physical address of the second wireless network element.

[0013] In one possible implementation, the processing unit is further configured to determine the distance between the second wireless network element and each of the first wireless network elements in the highest similarity cluster based on the updated physical address of the second wireless network element and the updated physical addresses of each of the first wireless network elements in the highest similarity cluster; the processing unit is further configured to determine the number of third wireless network elements in the highest similarity cluster based on the distance between the second wireless network element and each of the first wireless network elements in the highest similarity cluster; the third wireless network element is a first wireless network element whose distance is less than a first preset threshold; if the number of third wireless network elements is greater than a second preset threshold, the processing unit is further configured to determine the updated physical address of any first wireless network element in the highest similarity cluster as the updated physical address of the second wireless network element.

[0014] Thirdly, this application provides a physical address updating apparatus, which includes: a processor and a communication interface; the communication interface and the processor are coupled, and the processor is used to run computer programs or instructions to implement the physical address updating method as described in the first aspect and any possible implementation thereof.

[0015] Fourthly, this application provides a computer-readable storage medium storing instructions that, when executed on a terminal, cause the terminal to perform the physical address update method as described in the first aspect and any possible implementation thereof.

[0016] Fifthly, this application provides a computer program product containing instructions that, when run on a physical address updating device, causes the physical address updating device to perform the physical address updating method as described in the first aspect and any possible implementation thereof.

[0018] Specifically, the chip provided in this application also includes a memory for storing computer programs or instructions.

[0019] The above technical solution offers at least the following advantages: Compared to calculating the distance between each first wireless network element to obtain the data required for updating the physical address, this solution obtains the initial physical addresses of multiple first wireless network elements and multiple towers within the target area, and uses a clustering algorithm to cluster these elements into at least one cluster. Updating the initial physical address of the first wireless network element based on this clustering result (i.e., at least one cluster) significantly reduces the computational load during the physical address update process, thereby improving the efficiency of updating the initial physical address. Furthermore, since the physical addresses of towers are not easily changed, clustering multiple first wireless network elements and multiple towers together prevents repeated updates of the initial physical address of the first wireless network element when the stability of the updated physical address is poor (i.e., frequent changes). This further reduces the significant increase in computational load during the physical address update process, further improving the efficiency of updating the initial physical address.

[0025] The physical address update method, apparatus, and storage medium provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0026] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0027] The terms "first" and "second," etc., used in the specification and drawings of this application are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a specific order of objects.

[0028] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion.

Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0030] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0031] The following explanations of the terms used in the embodiments of this application are provided to facilitate the reader's understanding.

[0032] I. Density-based spatial clustering of applications with noise (DBSCAN)

[0033] DBSCAN is a density-based clustering algorithm. It defines a cluster as the largest set of density-connected points, and can divide regions with sufficiently high density into clusters. In noisy spatial databases, these clusters can be of arbitrary shapes.

[0034] II. K-Nearest Neighbor (KNN) Classification Algorithm

[0035] KNN is a classification algorithm used in data mining. In feature space, if the K nearest (i.e., the closest) sample points in the feature space mostly belong to the same category, then the sample also belongs to that category.

[0036] The above is a brief introduction to some of the concepts involved in the embodiments of this application.

[0037] In a mobile communication network, the address of a wireless network element can include a logical address and a physical address. The logical address can be obtained from the operation and maintenance center (OMC) and represented by a unique identity document (ID) to identify the address used by the wireless network element in the program. The physical address identifies the actual address of the wireless network element; both are of great importance in practical operation.

[0038] However, if the physical address of a wireless network element changes and this address is not updated, it can lead to inaccurate or incorrect device location identification. Therefore, in practice, it is necessary to update the physical address of a wireless network element when it changes to avoid inaccurate or incorrect location identification.

[0039] Currently, updating the physical address of a wireless network element can be achieved through the following methods 1 and 2.

[0040] Method 1: Update the physical address of wireless network elements based on the distance between them.

[0041] The method includes: determining the physical addresses of multiple remote radio units (RRUs) and / or multiple active antenna units (AAUs) within a region as preset physical addresses within that region, and determining the physical address of at least one wireless network element within a preset distance as a preset physical address based on the distance between each wireless network element within that region.

[0042] Problems with Method 1: Since the wireless network elements in a mobile communication network include wireless network elements from multiple operators with co-construction and sharing relationships, the number of wireless network elements in a mobile communication network is huge, which leads to a large amount of computation for updating the physical address of the wireless network elements.

[0043] For example, taking 400,000 wireless network elements as an example, the physical address update device uses big data analysis tools (e.g., the Statistical Package for the Social Sciences (SPSS)) to calculate the distances between these 400,000 wireless network elements. The physical address update device may need 2-3 hours to determine the distances between these 400,000 wireless network elements.

[0044] Moreover, in the situation where the network structure of the mobile communication network is adjusted or the engineering parameters of the mobile communication network are corrected, the physical address of the radio network element may change. If the physical address of the radio network element is updated based on the physical address that is likely to change, the stability of the physical address will be poor. When the stability of the updated physical address of the radio network element is poor, it is necessary to continuously repeat the above method to make the finally updated physical address of the radio network element have strong stability and reference value, which leads to a substantial increase in the computational amount and further results in a low efficiency of updating the physical address.

[0045] Method 2: Physical Address Updated Based on Radio Network Element Name

[0046] This method includes: obtaining the names of each radio network element and determining at least one radio network element with similar names as a set. Determining the distances between the radio network elements within the set and determining the physical address of any radio network element within the set that meets the preset distance as the physical address of all radio network elements within the set that meet the preset distance.

[0047] Exemplarily, Table 1 below shows the information of each radio network element (such as physical station name, evolved node B name (eNBName), and radio network element name (wireless network element name), etc.). If the distances between each radio network element in Table 1 below all meet the preset distance, the physical address of any radio network element (such as SZ_WZQ_HW_3F Weak Current Room of Building 5, Phase 1, Wuzhong District Financial City from _M_FL_A_1) can be determined as the physical address of each radio network element.

[0048] Table 1

[0049]

[0050]

[0051] Method 2 has several problems: Updating the physical address of a wireless network element based on its name may result in two wireless network elements with similar physical addresses being assigned two different physical addresses due to their dissimilar names. For example, two adjacent buildings with dissimilar names might be assigned to two different physical addresses, leading to low accuracy. Furthermore, different operators may use different naming conventions for the same wireless network element, potentially resulting in one wireless network element corresponding to multiple physical addresses, further reducing accuracy. Therefore, after updating the physical address of a wireless network element based on its name, Method 2 requires determining the distance between wireless network elements with similar names to accurately update the physical address of each element. However, this increases the computational load, reducing efficiency.

[0052] In summary, both Method 1 and Method 2 may result in a large amount of computation during the physical address update process, leading to low efficiency in updating the physical address.

[0053] In view of this, this application provides a physical address update method. Compared to calculating the distance between each first wireless network element to obtain the data required to update the physical address, the physical address update device obtains the initial physical addresses of multiple first wireless network elements and multiple towers within a target area, and uses a clustering algorithm to cluster the multiple first wireless network elements and multiple towers to obtain at least one cluster. The physical address update device updates the initial physical address of the first wireless network element based on the above clustering results (i.e., at least one cluster), which can greatly reduce the amount of computation in the process of updating the physical address of the first wireless network element, thereby improving the efficiency of updating the initial physical address of the first wireless network element. Furthermore, the physical address of the tower is not easily changed. The physical address update device clusters multiple first wireless network elements and multiple towers together, which can prevent the repeated updating of the initial physical address of the first wireless network element when the stability of the updated physical address of the wireless network element is poor (i.e., frequent changes), further reducing the significant increase in the amount of computation in the process of updating the physical address of the first wireless network element, and thus further improving the efficiency of updating the initial physical address of the first wireless network element.

[0054] The technical solutions provided in this application can be applied to various communication systems, such as New Radio (NR) communication systems using 5G, future evolution systems, or multiple communication convergence systems.

[0055] For example, such as Figure 1 As shown, Figure 1 A schematic diagram of a communication system provided in an embodiment of this application is shown. The communication system includes: a physical address update device 101, a first wireless network element 102, and a tower 103. Figure 1 The following description uses a communication system comprising a physical address update device 101, a first wireless network element 102, and a tower 103 as an example.

[0056] The physical address updating device 101 is used to obtain the initial physical addresses of multiple first wireless network elements 102 and multiple towers 103 within a target area; based on the initial physical addresses of the multiple first wireless network elements 102 and the multiple towers 103, the device clusters the multiple first wireless network elements 102 and the multiple towers 103 to obtain at least one cluster; if the target cluster includes at least one tower 103, the device updates the initial physical addresses of each first wireless network element 102 in the target cluster based on the physical address of at least one tower 103 to obtain the updated physical addresses of each first wireless network element 102 in the target cluster.

[0057] The first wireless network element 102 is used to provide an initial physical address to the physical address update device 101.

[0058] Tower 103 is used to provide physical addresses to physical address update device 101.

[0059] The target cluster is any one of at least one cluster.

[0060] Optionally, since there is a correspondence between wireless network elements and cells, the physical address update device 101 can also determine the updated physical address of each wireless network element as the updated physical address of the cell corresponding to each wireless network element.

[0061] In one example, the first wireless network element 102 can be any of the following nodes: base transceiver station (BTS), repeater, base station controller (BSC), operation and maintenance center radio (OMCR), small cell, wireless access point, transmission receive point (TRP), transmission point (TP), micro operator, and some other access node.

[0062] As an example, tower 103 can be an angle steel tower, a three-tube tower, a single-tube tower, a guyed tower, or other facilities that can transmit wireless signals.

These other communication networks can be Ethernet, radio access network (RAN), wireless local area networks (WLAN), etc. Communication interface 203 can be a module, circuit, communication interface, or any device capable of enabling communication.

[0069] Memory 204 is used to store instructions. These instructions can be computer programs.

[0070] The memory 204 can be a read-only memory (ROM) or other type of static storage device that can store static information and / or instructions; it can also be a random access memory (RAM) or other type of dynamic storage device that can store information and / or instructions; it can also be an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital universal optical discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, etc., without limitation.

[0071] It should be noted that the memory 204 can exist independently of the processor 201 or can be integrated with the processor 201.

[0079] To address the problems existing in the prior art, this application proposes a physical address update method that can improve efficiency in the process of updating the physical address of wireless network elements. For example... Figure 3 As shown, the method includes:

[0080] S301, The physical address update device obtains the initial physical addresses of multiple first wireless network elements and multiple towers within the target area.

[0081] Optionally, the initial physical address of the first wireless network element may include at least one of the following: latitude and longitude, time, and the identifier of the first wireless network element.

[0082] As one possible implementation, the process of the physical address update device obtaining the initial physical address of multiple first wireless network elements in the target area can be as follows: the physical address update device can obtain the physical addresses of multiple RRUs (or AAUs) in the target area, and determine the physical addresses of the multiple RRUs (or AAUs) as the initial physical addresses of the first wireless network elements corresponding to the multiple RRUs (or AAUs).

[0083] It is understandable that in the case of multiple RRUs being merged, the access network device will merge the multiple RRUs into one radio network element, so that each of the multiple RRUs corresponds to one radio network element. If the physical address of each RRU is determined based on the name of the radio network element, the physical address of each RRU will be determined as the physical address of the cell. However, in certain scenarios (e.g., high-speed rail scenarios), the installation locations of the various RRUs may be far apart, which will lead to low accuracy of the determined physical addresses of each RRU. In view of this, the physical address updating device provided in this application determines the initial physical address of the first radio network element corresponding to each RRU (or AAU) based on the physical addresses of multiple RRUs (or AAUs) in the target area, which can avoid misjudging the initial physical address of the first radio network element as the physical address of a single radio network element, thereby ensuring the accuracy of the initial physical address of the first radio network element.

[0084] As one possible implementation, the process of the physical address update device obtaining the physical addresses of multiple towers can be as follows: the physical address update device can obtain the physical addresses of multiple towers within the target area from the network management device side.

[0085] S302, The physical address update device clusters the multiple first wireless network elements and multiple iron towers based on the initial physical addresses of the multiple first wireless network elements and the physical addresses of the multiple iron towers, and obtains at least one cluster.

[0086] In one possible implementation, the above-mentioned S302 implementation process can be as follows: the physical address update device can merge the initial physical addresses of the above-mentioned multiple first wireless network elements and the location information of multiple towers, and use the DBSCAN algorithm to cluster the merged data to obtain at least one cluster.

[0087] As an optional implementation, the process of using the DBSCAN algorithm to cluster the merged data to obtain at least one cluster can be determined by the following steps 1 to 7.

[0088] Step 1: The physical address update device determines the scan radius (eps) and the minimum number of contained points (minPts).

[0089] Step 2: The physical address update device can determine multiple sampling points based on multiple first wireless network elements and multiple towers, select k sampling points in the target area, and record any one of the k sampling points (for example, sampling point O) as the target circle.

[0090] Step 3: The physical address update device can determine the scanning range based on the target dot and the scanning radius, and determine the sampling points located within the scanning range among multiple sampling points as the sampling points in cluster #1.

[0091] It should be noted that the above sampling points can be the first wireless network element or a tower.

[0092] Step 4: The physical address update device determines whether the number of sampling points within the scanning range is greater than or equal to the minimum number of contained points.

[0093] If the number of sampling points within the scanning range is greater than or equal to the minimum number of points, the physical address update device executes step 5.

[0094] Step 5: The physical address update device determines any one sampling point (e.g., sampling point A) from the sampling points within the scanning range and updates sampling point A to the target circle. Steps 3 and 4 are executed again until the number of sampling points within the scanning range is less than 1, thus ending the cluster #1 determination process.

[0095] If the number of sampling points within the scanning range is less than the minimum number of points, the physical address update device executes step 6.

[0096] Step 6: The physical address update device directly ends the cluster #1 determination process and marks the cluster identifier of the cluster as -1.

[0097] Step 7: The physical address update device determines k clusters based on steps 2 to 6 above.

[0098] It should be noted that in a cluster (e.g., cluster #1) determined by the physical address update device, each sampling point has the same cluster identifier and is not -1. If the cluster identifier is -1, it indicates that there is only one sampling point in that cluster, that is, there are no other sampling points within the scan radius of that sampling point.

[0099] Understandably, if the physical address update device only considers the initial physical address of the first wireless network element during the clustering process, the stability and accuracy of the clustering results will be low, especially given the susceptibility of the initial physical address to change. Therefore, the physical address update device will struggle to determine the updated physical address of the first wireless network element based on these less accurate clustering results. However, the number of towers is relatively small, and their physical addresses are relatively stable and accurate. Therefore, the physical address update device can cluster multiple first wireless network elements and multiple towers, improving the stability and accuracy of the clustering results, and consequently, enhancing the stability and accuracy of the updated physical address of the first wireless network element.

[0100] S303. When the target cluster includes at least one tower, the physical address updating device updates the initial physical address of each first wireless network element in the target cluster based on the physical address of the at least one tower, so as to obtain the updated physical address of each first wireless network element in the target cluster.

[0101] The target cluster is any one of at least one cluster.

[0102] In one possible implementation, the above-mentioned S303 process can be as follows: when the number of towers in the target cluster is equal to 1, the physical address updating device can determine the physical address of the tower as the updated physical address of each wireless network element in the target cluster.

[0103] When the number of towers in the target cluster is greater than 1, the physical address update device can determine the physical addresses of multiple towers in the target cluster and set the physical address of any one of the multiple towers as the updated physical address of each wireless network element in the target cluster.

[0104] If the target cluster includes more than one tower, the physical address update device can also obtain the IDs of the multiple towers and sort them based on these IDs to obtain a first sequence. The physical address update device then determines the physical address of the first tower in the first sequence as the updated physical address of each first wireless network element in the target cluster.

[0105] If the target cluster includes more than one tower, the physical address update device can also determine the physical address of the cluster center, and determine the distance between the towers and the cluster center based on the physical address of the cluster center and the physical addresses of the towers. The physical address update device sorts the towers from smallest to largest based on the distance, obtaining a second sequence, and determines the physical address of the tower at the first position in the second sequence as the updated physical address of each first wireless network element in the target cluster.

[0106] For example, Table 2 below shows information about multiple clusters. As shown in Table 2, the physical address update device can filter towers and wireless network elements according to network type. For a cluster with cluster identifier (index_y) of 14, this cluster includes a tower (i.e., the tower with source signal name of Fengxian Wanggou Liliu Equipment Room, or the tower with location area code_cellidentity_ENB ID_e-utran cell identifier, LAC_CI_ENBID_ECI) of 320322000000000000). In this way, the physical address update device can determine the physical address of the above tower (i.e., the longitude and latitude shown in Table 2 below) as the updated physical address of the fourth-generation mobile communication technology (4G) wireless network element of each designated operator in the cluster.

[0107] Table 2 below also shows multiple clusters with a cluster identifier of -1. Each cluster with a cluster identifier of -1 contains only one wireless network element. For example, a cluster with a cluster identifier of -1 contains only one wireless network element (i.e., the wireless network element corresponding to the tower with the source signal name XZ_FX_HW_Fengxian Wanggou Town Qianliuji_FLN9). In this way, the physical address updating device can determine the physical address of the aforementioned tower (i.e., the longitude (116.37207) and latitude (34.64817) shown in Table 2 below) as the updated physical address of the wireless network element.

[0110]

[0111] In an optional embodiment, if the target cluster does not include towers, the physical address updating device determines at least one set based on the initial physical addresses of each first wireless network element in the target cluster, and counts the number of first wireless network elements in each set within the at least one set. The physical address updating device determines the initial physical address of the first wireless network element in the set with the largest number of first wireless network elements as the updated physical address of each first wireless network element in the target cluster.

[0112] In this case, the initial physical addresses of the first wireless network elements included in a set are the same, while the initial physical addresses of the first wireless network elements in different sets are different.

[0113] Optionally, if at least two of the aforementioned sets have the same number of first wireless network elements, the physical address updating device may select any one of the aforementioned at least two sets and determine the initial physical address of the first wireless network element in the aforementioned set as the updated physical address of each first wireless network element in the target cluster.

[0114] Understandably, when the target cluster does not include towers, the physical address updating device determines the updated physical address of the first wireless network element based on the initial physical address of the first wireless network element in the set with the largest number of identical initial physical addresses in the target cluster. This avoids the problem of not being able to update the physical address of the first wireless network element when the target cluster does not include towers. Furthermore, determining the updated physical address of the first wireless network element based on the initial physical address of the first wireless network element in the set with the largest number of identical initial physical addresses in the target cluster can also ensure the accuracy of the updated physical address of each first wireless network element in the target cluster to a certain extent.

[0115] The above technical solution brings at least the following beneficial effects: Compared to calculating the distance between each first wireless network element to obtain the data required for updating the physical address, the physical address updating device obtains the initial physical addresses of multiple first wireless network elements and multiple towers within the target area, and uses a clustering algorithm to cluster the multiple first wireless network elements and multiple towers to obtain at least one cluster. The physical address updating device updates the initial physical address of the first wireless network element based on the above clustering results (i.e., at least one cluster), which can greatly reduce the computational load during the physical address updating process of the first wireless network element, thereby improving the efficiency of updating the initial physical address of the first wireless network element. Furthermore, since the physical address of the towers is not easily changed, the physical address updating device clusters multiple first wireless network elements and multiple towers together, preventing repeated updates of the initial physical address of the first wireless network element when the stability of the updated physical address of the wireless network element is poor (i.e., frequently changing), further reducing the significantly increased computational load during the physical address updating process of the first wireless network element, and thus further improving the efficiency of updating the initial physical address of the first wireless network element.

[0116] In an optional embodiment, if the physical address of a first wireless network element in the target area changes or a new wireless network element appears in the target area, the physical address updating device can update the current physical address of a second wireless network element (including the first wireless network element whose initial physical address has changed among multiple first wireless network elements, and / or the new wireless network element other than multiple first wireless network elements in the target area) to determine the updated physical address of the second wireless network element, thereby avoiding inaccurate physical addresses of the second wireless network element. Figure 3 Based on the illustrated method embodiments, this embodiment provides a possible implementation method, combined with Figure 3 ,like Figure 4 As shown, the process by which the physical address update device determines the updated physical address of the second wireless network element can be determined through the following steps S401 to S403.

[0117] S401, The physical address update device obtains the current physical address of the second wireless network element in the target area.

[0118] The second wireless network element includes at least one of the following: a first wireless network element whose initial physical address has changed among a plurality of first wireless network elements, and a newly added wireless network element other than a plurality of first wireless network elements in the target area.

[0119] Optionally, the implementation process of S401 can be understood by referring to the implementation process of the physical address update device obtaining the initial physical addresses of multiple first wireless network elements in the target area in S301, which will not be repeated here.

[0120] S402, the physical address update device determines the similarity between the current physical address of the second wireless network element and at least one cluster based on the classification algorithm and the current physical address of the second wireless network element.

[0121] As one possible implementation, the above-mentioned S402 process can be as follows: The physical address updating device can obtain the updated physical address of any wireless network element in each of the at least one cluster, and determine the distance between the second wireless network element and each of the at least one cluster based on the current physical address of the second wireless network element and the updated physical address of any wireless network element in each of the at least one cluster. The physical address updating device can use the KNN algorithm and the distance between the second wireless network element and each of the at least one cluster to classify the second wireless network element and obtain the similarity between the second wireless network element and each of the at least one cluster.

[0122] Understandably, the higher the similarity between a second wireless network element and a cluster, the closer the second wireless network element is to that cluster. Conversely, the lower the similarity between a second wireless network element and a cluster, the farther the second wireless network element is from that cluster.

[0123] S403, The physical address update device determines the updated physical address of any wireless network element in the cluster with the highest similarity as the updated physical address of the second wireless network element.

[0124] As one possible implementation, the above-mentioned S403 implementation process can be as follows: the physical address updating device can sort the similarity between the second wireless network element and each of the at least one cluster from high to low to obtain a third sequence, and determine the updated physical address of any wireless network element in the cluster corresponding to the first similarity in the third sequence as the updated physical address of the second wireless network element.

[0125] Optionally, after the physical address updating device determines the updated physical address of the second wireless network element, the physical address updating device can also verify the updated physical address of the second wireless network element to ensure the accuracy of the updated physical address of the second wireless network element.

[0126] In an optional embodiment, the physical address update device verifies the updated physical address of the second wireless network element as follows: Based on the updated physical address of the second wireless network element and the updated physical addresses of each wireless network element in the cluster with the highest similarity, the physical address update device determines the distance between the second wireless network element and each wireless network element in the cluster with the highest similarity. Based on the distance between the second wireless network element and each wireless network element in the cluster with the highest similarity, it determines the number of third wireless network elements in the cluster with the highest similarity. If the number of third wireless network elements is greater than a second preset threshold, the physical address update device determines the updated physical address of any wireless network element in the cluster with the highest similarity as the updated physical address of the second wireless network element. The third wireless network element is the wireless network element whose distance is less than the first preset threshold.

[0127] Optionally, if the number of third wireless network elements is less than or equal to the second preset threshold, the physical address update device can determine the current physical address of the second wireless network element as the updated physical address of the second wireless network element.

[0128] As an example, the physical address update device can set a first preset threshold and a second preset threshold based on experience. For example, the physical address update device can set the first preset threshold to 50 meters and the second preset threshold to 1. The above is only an exemplary illustration of the first preset threshold and the second preset threshold, and the first preset threshold and the second preset threshold can also be other values ​​(for example, the first preset threshold is 70 meters and the second preset threshold is 2), and this application does not impose any limitations on them.

[0129] In another optional embodiment, the process of the physical address update device verifying the updated physical address of the second wireless network element can be as follows: The physical address update device can determine the distance between the second wireless network element and each wireless network element in the highest similarity cluster based on the updated physical address of the second wireless network element and the updated physical addresses of each wireless network element in the highest similarity cluster, and determine the number of fourth wireless network elements in the highest similarity cluster based on the distance between the second wireless network element and each wireless network element in the highest similarity cluster. If the number of fourth wireless network elements is less than or equal to a third preset threshold, the physical address update device determines the updated physical address of any wireless network element in the highest similarity cluster as the updated physical address of the second wireless network element. Here, the fourth wireless network element is the wireless network element whose distance is greater than the first preset threshold.

[0130] Optionally, if the number of fourth wireless network elements is greater than the third preset threshold, the physical address update device determines the current physical address of the second wireless network element as the updated physical address of the second wireless network element.

[0131] As an example, the physical address update device can set a third preset threshold based on experience. For example, the physical address update device can set the third preset threshold to 60. The above is merely an exemplary description of the third preset threshold, and the third preset threshold can also be other values ​​(for example, the third preset threshold is 100), and this application does not impose any limitations on it.

[0132] Understandably, the physical address update device verifies the updated physical address of the second wireless network element to avoid physical address mismatch and further determine the accuracy of the updated physical address of the second wireless network element.

[0133] Optionally, the above Figure 4 The physical address update method shown can be applied when the current physical address of the second wireless network element is different from the initial physical address of any first wireless network element. However, if the current physical address of the second wireless network element is the same as the initial physical address of any first wireless network element, the physical address update device can directly determine the updated physical address of the first wireless network element whose initial physical address is the same as the current physical address of the second wireless network element as the updated physical address of the second wireless network element. This saves the physical address update device from updating the physical address of the second wireless network element based on the KNN algorithm, thus reducing the computational load.

[0134] The above technical solution brings at least the following beneficial effects: When the target area includes wireless network elements whose physical addresses have changed, or when a new wireless network element (i.e., a second wireless network element) appears in the target area, the physical address updating device can quickly and accurately determine the category to which the second wireless network element belongs (i.e., the cluster with the highest similarity to the second wireless network element) using a classification algorithm, and determine the updated physical address of the second wireless network element based on the category to which the second wireless network element belongs. In this way, the classification algorithm can update the current physical address of the second wireless network element based on the similarity between the second wireless network element and each cluster, without having to calculate the distance between the second wireless network element and each wireless network element in the target area to update the current physical address of the second wireless network element, reducing the amount of computation and thus improving the efficiency of updating the physical address.
