Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, and in particular to a method, apparatus and storage medium for cross-area coverage processing. Background Technology
[0002] Currently, base stations transmit signals via radio electromagnetic waves. However, the propagation range of radio electromagnetic waves cannot be precisely controlled. This can lead to a situation where the actual coverage area of a cell exceeds the coverage area of one or more other cells, entering the coverage area of other cells, resulting in over-coverage and thus affecting network performance.
[0003] In existing technologies, the detection of over-coverage is carried out through manual drive testing. Specifically, the drive test logs are analyzed to identify a cell, and then the sampling points with valid over-coverage are identified from all the sampling points in that cell. When the ratio of the number of such sampling points to the total number of sampling points exceeds a certain threshold, it is determined that the cell has over-coverage.
[0004] However, due to the wide and complex distribution of residential areas in real life, the above-mentioned cross-coverage detection method requires a lot of human and material resources, which not only results in excessively high detection costs, but also low detection accuracy and efficiency, leading to low overall processing efficiency for cross-coverage. Summary of the Invention
[0005] This application provides a method, apparatus, and storage medium for handling cross-area coverage, which can solve the problem of low processing efficiency for cross-area coverage.
[0006] To achieve the above objectives, this application adopts the following technical solution:
[0007] In a first aspect, this application provides a method for handling cross-coverage issues. The method includes: acquiring an Auxiliary GPS Measurement Report (AGPS MR) of a serving cell within a historical time period, wherein the AGPS MR includes the Reference Signal Received Power (RSRP) of the serving cell, the RSRP of at least one neighboring cell of the serving cell, location information of at least one sampling point in the serving cell, and location information of the at least one neighboring cell; calculating a first distance from the target sampling point to each of the at least one neighboring cell based on the location information of the target sampling point and the location information of the at least one neighboring cell, wherein the target sampling point is a sampling point among the at least one sampling points; and determining a target neighboring cell that meets preset conditions from the at least one neighboring cell based on the RRP of the serving cell, the RSRP of the at least one neighboring cell, the first coverage distance of the at least one neighboring cell, and the first distance, wherein the target neighboring cell is a neighboring cell with cross-coverage issues.
[0008] Based on the above technical solution, the cross-coverage processing method provided in this application embodiment can first obtain the Auxiliary GPS Measurement Report (AGPS MR) of the serving cell, and calculate the first distance from the target sampling point to each neighboring cell of the serving cell based on the location information of at least one sampling point and the location information of at least one neighboring cell included in the AGPS MR. Then, based on the Reference Signal Received Power (RSRP) of the serving cell and the RSRP of each neighboring cell included in the AGPS MR, as well as the first coverage distance of each neighboring cell and the aforementioned first distance, the target neighboring cell that meets the preset conditions is determined. This target neighboring cell is a neighboring cell with cross-coverage. Since the AGPS MR obtained above can accurately indicate the latitude and longitude of the cell and the sampling point, the accurate first distance can be calculated quickly. Furthermore, the RSRP of the serving cell and the RSRP of the neighboring cells are also used as reference factors for determining the target neighboring cell, further ensuring the accuracy of the determined target neighboring cell having cross-coverage, thereby improving the overall processing efficiency of cross-coverage.

[0011] In a third possible implementation of the first aspect, the preset conditions include: the RSRP of the serving cell is greater than or equal to a first threshold; the difference between the RSRP of the serving cell and the RSRP of at least one neighboring cell is less than or equal to a second threshold; the first distance is greater than the first coverage distance, and the ratio of the first distance to the second distance is greater than or equal to a third threshold.

[0030] The cross-area coverage processing method, apparatus, and storage medium provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0031] 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.
[0032] 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.
[0033] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.
[0034] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. 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.
[0035] In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0036] Currently, base stations rely on radio electromagnetic waves for transmission. However, the propagation of radio electromagnetic waves cannot be precisely controlled. In some cases, this can cause the coverage area of a base station to exceed the preset range and enter the coverage area of other base stations.
[0037] For example, such as Figure 1 As shown, taking the overlapping coverage areas of cells A, B, and C as an example, the coverage area of cell A forms discontinuous regions 1 and 2 within the coverage areas of cells B and C. Furthermore, cell A extends beyond the coverage area of cell B and overlaps with the coverage area of cell C. This indicates that cell A has out-of-area coverage, meaning that cell A exhibits out-of-area coverage.
[0038] Out-of-area coverage can severely impact a cell's network performance, leading to increased network interference, chaotic network handover relationships, excessive traffic absorption, and capacity issues. To mitigate the negative impact of out-of-area coverage on network performance, it is necessary to conduct an accurate and effective assessment of whether out-of-area coverage exists in a cell, i.e., to perform out-of-area coverage assessment.
[0039] In existing technologies, the presence of out-of-area coverage is generally detected through drive testing. Specifically, manual drive test logs are analyzed to identify cells with poor network performance. Then, sampling points that meet the criteria for out-of-area coverage are selected from all sampling points of that cell. Finally, it is determined whether the ratio of the number of selected sampling points to the total number of sampling points of that cell exceeds a predetermined threshold. If the ratio exceeds the predetermined threshold, it is determined that the cell has out-of-area coverage.
[0040] However, due to the wide and complex distribution of cells in wireless networks, conducting a manual drive test requires a large amount of human and material resources, which not only increases the cost pressure on network operators, but also results in low efficiency and accuracy of manual drive tests, leading to low overall efficiency in handling cross-area coverage.
[0041] To address the low efficiency of handling cross-coverage issues in existing technologies, this application provides a cross-coverage processing method. First, it acquires the Assisted Global Positioning System Measurement Report (AGPS MR) of the serving cell. Based on the location information of at least one sampling point and at least one neighboring cell included in the AGPS MR, it calculates a first distance from the target sampling point to each neighboring cell of the serving cell. Then, based on the Reference Signal Receiving Power (RSRP) of the serving cell and the RSRP of each neighboring cell included in the AGPS MR, along with the first coverage distance of each neighboring cell and the aforementioned first distance, it identifies the neighboring cells with cross-coverage issues. Since the acquired AGPS MR accurately indicates the latitude and longitude of the cell and sampling point, an accurate first distance can be quickly calculated. Furthermore, by using the RSRP of the serving cell and the RSRP of the neighboring cells as reference factors in determining the target neighboring cells, the accuracy of identifying cross-coverage issues in the target neighboring cells is further ensured, thereby improving the overall processing efficiency of cross-coverage issues.
[0042] For example, such as Figure 2 As shown, when obtaining the AGPS MR of the serving cell, software (such as a network management system) is used to query and count the AGPS MR of the cell of the third generation (3G) base station (NodeB) or the fourth generation (4G) base station (eNodeB) via the transmission network.
[0043] like Figure 3 The diagram shows a flowchart of a cross-coverage processing method provided in an embodiment of this application. The method includes the following steps S101 to S103:
[0044] S101. Obtain the AGPS MR of the serving cell within the historical time period.
[0045] In this embodiment of the application, the aforementioned historical time period can be a manually set time period. For example, the aforementioned historical time period is the past 3 days.
[0046] In this embodiment of the application, the aforementioned serving cell can be the cell that the user equipment is connecting to among multiple cells of the base station.
[0047] For example, the aforementioned base station can be one or more of a 3G base station, a 4G base station, or a fifth-generation (5G) base station.
[0048] For example, the 3G base station can be a NodeB, the 4G base station can be an eNodeB, and the 5G base station can be a gNB.
[0049] In this embodiment of the application, the aforementioned AGPS MR includes the Reference Signal Received Power (RSRP) of the serving cell and the RSRP of at least one neighboring cell of the serving cell.
[0050] In this embodiment of the application, the AGPS MR also includes the location information of at least one sampling point in the serving cell and the location information of at least one neighboring cell.
[0051] For example, the aforementioned AGPS MR is the measurement data that the cell requires user equipment to report. Each user equipment is a sampling point, which generates a large amount of measurement data. Each sampling point contains complete AGPS MR data, including Timing Advance (TA), Reference Signal Receiving Power (RSRP) of the serving cell, Reference Signal Received Quality (RSRQ), neighbor cell information, neighbor cell signal strength, and sampling point location information.
[0052] It should be noted that RSRP refers to signal strength, which is used to measure the quality of cell signal; the location information can be latitude and longitude coordinates, used to accurately determine geographical location.
[0053] For example, the RSRP mentioned above refers to the average signal power received on all resource elements (REs) within the bandwidth used by the cell as measured by the user equipment, within the identifier of the reference signal (RS), which is used to carry the cell-specific reference signal, and represents the signal power of the cell.
[0054] In this embodiment of the application, the above-mentioned at least one neighboring cell refers to a cell other than the serving cell signal that the user equipment measures when it is connected to the serving cell.
[0055] It should be noted that the aforementioned serving cell and at least one of its neighboring cells belong to the same base station.
[0056] S102. Based on the location information of the target sampling point and the location information of at least one neighboring cell, calculate the first distance from the target sampling point to each of the at least one neighboring cell.
[0057] In this embodiment of the application, the target sampling point is a sampling point among the above-mentioned at least one sampling point.
[0058] In this embodiment of the application, the sampling point in the serving cell measures the signal of the serving cell and also measures the signal of the surrounding cells (i.e., at least one neighboring cell) and reports it to the serving cell. Therefore, the location information of the surrounding cells can be parsed from the AGPS MR of the serving cell.
[0059] For example, the location information of the above-mentioned at least one neighboring cell can be the latitude and longitude coordinates of the at least one neighboring cell.
[0060] For example, taking the target sampling point as sampling point k, the serving cell as cell 1, and the at least one neighboring cell including cell 2, cell 3, and cell 4 as an example, when measuring signals, sampling point k in cell 1 will not only measure the signals connected to itself in cell 1, but also measure the signals of surrounding cells 2, 3, and 4, and report them to cell 1. Therefore, the latitude and longitude coordinates of cells 2, 3, and 4 can also be obtained. Then, based on the latitude and longitude coordinates of sampling point k and cells 2, 3, and 4, the distances from sampling point k to cells 2, 3, and 4 (i.e., the aforementioned first distance) are calculated.
[0061] It should be noted that each neighboring cell corresponds to a first distance.
[0062] Further optionally, in this embodiment of the application, the AGPS MR also includes the location information of the serving cell. Before step S102, the cross-coverage processing method provided in this embodiment of the application may further include the following steps S102a and S102b:
[0063] S102a. Based on the location information of the serving cell and the location information of at least one sampling point, calculate the second distance from each sampling point to the serving cell.
[0064] In this embodiment of the application, the location information can be latitude and longitude.
[0065] For example, the location information of the aforementioned serving cell can be the latitude and longitude of the serving cell.
[0066] For example, the location information of the above-mentioned at least one sampling point can be the latitude and longitude of the at least one sampling point.
[0067] For example, taking at least one sampling point including sampling point A and the serving cell being cell B, if the latitude and longitude coordinates of sampling point A over the past three days are A(ja, wa) and the latitude and longitude coordinates of cell B are (jb, wb), then the distance between the two latitude and longitude coordinates can be calculated according to formula (1). Formula (1) is as follows:
[0068]
[0069] Where R is the Earth's radius, arccos is the inverse cosine function, Cos is the cosine function, and Sin is the sine function.
[0070] S102b: The sampling points whose second distance is less than or equal to the second coverage distance of the serving cell are determined as target sampling points.
[0071] In this embodiment of the application, the second coverage distance is used to indicate the preset coverage distance of the serving cell signal.
[0072] For example, after calculating the second distance using the above formula (1), the second distance from each sampling point to the serving cell is compared with the preset coverage distance of the serving cell signal, and the sampling points within the preset coverage distance of the serving cell signal are taken as target sampling points.
[0073] S103. Based on the RSRP of the serving cell, the RSRP of at least one neighboring cell, the first coverage distance and the first distance of at least one neighboring cell, determine the target neighboring cell that meets the preset conditions from at least one neighboring cell.
[0074] In this embodiment of the application, the target neighboring cell is a neighboring cell that has cross-coverage.
[0075] In this embodiment of the application, the first coverage distance is used to indicate the preset coverage distance of the neighboring cell signal.
[0076] For example, the preset coverage distance depends on the coverage scenario of the cell. For instance, if the coverage scenario is a core urban area, the preset coverage distance is usually set to 300-400 meters; if the coverage scenario is a suburban area, the preset coverage distance is set to 700-800 meters; and if the coverage scenario is a rural open area, the preset coverage distance is set to 1500-1600 meters.
[0077] It should be noted that due to the complexity of the wireless environment, with various buildings and obstacles, the preset coverage distance for each cell is different.
[0078] Further, optionally, in this embodiment of the application, in conjunction with the above step S102a, the above preset conditions include the following P1 to P3:
[0079] P1. The RSRP of the above-mentioned serving cell is greater than or equal to the first threshold.
[0080] For example, the first threshold mentioned above can be a manually set value, which can be flexibly set according to the actual scenario. For example, the first threshold mentioned above is -105 dBm.
[0081] P2. The difference between the RSRP of the serving cell and the RSRP of at least one neighboring cell is less than or equal to the second threshold.
[0082] For example, the second threshold mentioned above can be a manually set value, which can be flexibly set according to the actual scenario. For example, the second threshold mentioned above is 3.
[0083] P3. The first distance is greater than the first coverage distance, and the ratio of the first distance to the second distance is greater than or equal to the third threshold.
[0084] For example, the aforementioned third threshold can be a manually set value, which can be flexibly set according to the actual scenario. For instance, the aforementioned third threshold is 1.5.
[0085] It should be noted that the above-mentioned preset conditions are only met if P1, P2, and P3 are all satisfied simultaneously. In other words, neighboring cells that simultaneously satisfy P1, P2, and P3 are considered as target neighboring cells.
[0086] For example, taking the first threshold as -105dBm, the second threshold as 3dB, the third threshold as 1.5, and the at least one neighboring cell including neighboring cell D as an example: If the RSRP of the serving cell is ≥ -105dBm, and the RSRP of the serving cell minus the RSRP of neighboring cell D is ≤ 3dB (e.g., -105 - (-107) = 2), and the distance from the sampling point to neighboring cell D is greater than the preset coverage distance of neighboring cell D (i.e., the first coverage distance mentioned above), and the distance from the sampling point to neighboring cell D / the distance from the sampling point to the serving cell is ≥ 1.5, then neighboring cell D is determined to be a target neighboring cell with cross-coverage.
[0087] Thus, by setting the above three conditions, it is possible to accurately find the target neighboring cell that is within the preset coverage distance of the serving cell signal, has a good serving cell signal strength, and whose neighboring cell signals are not much different, while the distance from the sampling point to the neighboring cell is much greater than the preset coverage distance of the neighboring cell signal.
[0088] In the cross-coverage processing method provided in this application embodiment, the Auxiliary GPS Measurement Report (AGPS MR) of the serving cell is first obtained. Based on the location information of at least one sampling point in the serving cell and the location information of at least one neighboring cell included in the AGPS MR, a first distance from the target sampling point to each neighboring cell of the serving cell is calculated. Then, based on the Reference Signal Received Power (RSRP) of the serving cell and the RSRP of each neighboring cell included in the AGPS MR, as well as the first coverage distance of each neighboring cell and the aforementioned first distance, a target neighboring cell that meets preset conditions is determined. This target neighboring cell is a neighboring cell with cross-coverage. Since the AGPS MR obtained above can accurately indicate the latitude and longitude of the cell and the sampling point, the accurate first distance can be calculated quickly. Furthermore, the RSRP of the serving cell and the RSRP of the neighboring cells are also used as reference factors for determining the target neighboring cell, further ensuring the accuracy of the determined target neighboring cell having cross-coverage, thereby improving the overall processing efficiency of cross-coverage.
[0089] Optionally, in this embodiment of the application, after step S101 above, the cross-coverage processing method provided in this embodiment of the application may further include the following step S101a:
[0090] S101a. Establish a base station database.
[0091] In this embodiment of the application, the base station database is used to store the AGPS MR of the serving cell and the AGPS MR of at least one neighboring cell.
[0092] For example, the engineering data stored in the aforementioned base station database is recorded when the cell is constructed. This engineering data includes the cell's location information, frequency, broadband, and other information.
[0093] In this embodiment of the application, after the base station database stores engineering data, if the server needs to obtain the AGPS MR, it can directly obtain it from the database.
[0094] In this way, all the base station data is stored in the database, making it more convenient and efficient for the server to retrieve the data later.
[0095] Optionally, in this embodiment of the application, after step S103 above, the cross-coverage processing method provided in this embodiment of the application may further include the following step S104:
[0096] S104. If, within the second coverage distance, the ratio of the sampling point of the target neighboring cell to at least one sampling point exceeds the fourth threshold, reduce the power of the target neighboring cell or decrease the coverage range of the target neighboring cell.
[0097] In this embodiment of the application, after the target neighboring cell is determined, if there is a sampling point of the target neighboring cell among all the sampling points of the serving cell, and the proportion of the sampling points of the target neighboring cell exceeds the fourth threshold, then the target neighboring cell is considered to be a neighboring cell with serious cross-coverage and needs to be processed.
[0098] For example, the fourth threshold mentioned above can be a pre-defined value, which can be flexibly set according to the actual scenario. For example, the fourth threshold mentioned above is 20%.
[0099] For example, taking the fourth threshold of 20% as an example. If there are 100 sampling points in the serving cell and 80 sampling points in the target neighboring cell, and 30 sampling points in the target neighboring cell are within the preset coverage distance of the serving cell signal, then 30 / 100 = 30% > 20%, and the target neighboring cell is a neighboring cell with serious over-coverage, which needs further processing.
[0100] In this embodiment of the application, after identifying neighboring cells with severe cross-coverage issues, the cross-coverage can be improved through the following methods Q1 and Q2:
[0101] Q1. Based on the current power of the target neighbor cell, reduce the power of the target neighbor cell by 1dB each time through the network management system.
[0102] It should be noted that, within the preset number of reductions in Q1 (e.g., 3 times), if the ratio of the sampling points of the target neighboring area to at least one sampling point is less than the fourth threshold (e.g., 20%), it indicates that the over-coverage issue has been resolved, and the adjustment stops. If it still exceeds the fourth threshold, the Q2 method is used to continue the adjustment.
[0103] Q2. After the number of reductions reaches a preset number (e.g., 3 times), the power of the target neighboring cell will no longer be reduced. Instead, the antenna angle of the target neighboring cell will be adjusted, with each adjustment being a mechanical downtilt of 1°, until the ratio of the sampling point of the target neighboring cell to at least one sampling point is less than the fourth threshold, at which point the adjustment will stop.
[0104] It should be noted that the antenna angle adjustment in Q2 above can be achieved by remotely controlling the antenna or by manual adjustment on-site.
[0105] Thus, when a cell with severe over-coverage is detected, the problem of over-coverage is effectively solved by combining power reduction and coverage distance adjustment, thereby improving the efficiency of handling over-coverage.
[0106] This application embodiment can divide the cross-coverage processing device into functional modules or functional units according to the above method example. For example, each function can be divided into a separate functional module or functional unit, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or in software functional modules or functional units. The module or unit division in this application embodiment is illustrative and only represents one logical functional division; other division methods may be used in actual implementation.

[0110] Optionally, in this embodiment of the application, the AGPS MR further includes the location information of the serving cell; the calculation unit 202 is further configured to calculate, before calculating the first distance from the target sampling point to each of the at least one neighboring cells based on the location information of the target sampling point and the location information of the at least one neighboring cell, a second distance from each of the at least one sampling point to the serving cell based on the location information of the serving cell and the location information of the at least one sampling point; the determination unit 203 is further configured to determine the sampling points whose second distance obtained by the calculation unit 202 is less than or equal to the second coverage distance of the serving cell as the target sampling points.

[0113] In the cross-coverage processing apparatus provided in this application embodiment, the Auxiliary GPS Measurement Report (AGPS MR) of the serving cell can be obtained first. Based on the location information of at least one sampling point in the serving cell and the location information of at least one neighboring cell included in the AGPS MR, a first distance from the target sampling point to each neighboring cell of the serving cell can be calculated.

Furthermore, the RSRP of the serving cell and the RSRP of the neighboring cells are also used as reference factors for determining the target neighboring cell, further ensuring the accuracy of the determined target neighboring cell having cross-coverage, thereby improving the overall processing efficiency of cross-coverage.
