Description

Technical Field

[0001] The embodiments of the present invention relate to the field of mobile communication technology, and in particular to a method, device, electronic device, storage medium and program product for identifying cells with abnormal coverage. Background Art

[0002] With the popularization of 5G (fifth generation mobile communication technology) terminals and the vigorous promotion and construction of 5G base stations, the current proportion of 5G traffic in the total network traffic has basically exceeded 50%, and the position of 5G networks in mobile communication networks has become increasingly critical. How to ensure the perception of 5G users in the use of mobile networks has become increasingly important. Since the current planning of 5G networks is basically based on the mature 4G (fourth generation mobile communication technology) network, the coverage depth and breadth of the 5G network are basically consistent with the 4G network, but the newly built 5G equipment has certain differences in antenna height, azimuth and downtilt angle from 4G equipment, so that the coverage effect of the 5G network cannot achieve the same effect as the 4G network; one of the key tasks of 5G network optimization is to identify whether the coverage of a single 5G cell is consistent with that of a single 4G cell, and to carry out network adjustments for inconsistent cells, so as to improve the coverage quality of the 5G network. The current method of identifying whether the coverage of a single 4G / 5G cell is consistent is mainly through road network and fixed-point testing, etc., which outputs the coverage overlap of a single 4G / 5G cell by field network and fixed-point testing. Due to the large scale of communication facilities, it consumes a lot of manpower and material resources, and the test time is long. Field testing cannot traverse all coverage locations of the cell, and there are certain situations where human errors are introduced.

[0003] Therefore, it becomes particularly critical to intelligently identify cells with abnormal 5G coverage under the same coverage requirements of a single 4G / 5G cell. Summary of the invention

[0067] First, a single 4G / 5G cell that needs to meet the same coverage requirements is identified through the design and construction plan. In the embodiment of the present invention, considering that the MR (Measurement Report) reported by the 5G cell does not have longitude and latitude information, it is impossible to directly present and analyze the coverage of the 4G and 5G cells on the map; based on this, the embodiment of the present invention proposes to use the MR with AGPS (Assisted Global Positioning System) information reported by the 4G cell for subsequent analysis. Specifically, in order to identify the 4G cell where the AGPS-MR of the target 5G cell may exist, the embodiment of the present invention adopts the 5G cell coverage distance and cell cross search method for identification; and the 5G AGPS-MR reported by the 4G cell (in the embodiment of the present invention, the AGPS-MR reported by the 4G cell that may be in the same coverage area as the 5G cell is regarded as the 5G AGPS-MR) is removed from the 5G MR sampling points reported by the isolated terminal in the 4G cell, thereby obtaining the effective 5G AGPS-MR reported by the 4G cell. The method for obtaining the effective 4G AGPS-MR reported by the 4G cell is basically the same as the method for obtaining the effective 5G AGPS-MR reported by the 4G cell. Finally, the coverage of the single 4G / 5G cell with the same coverage requirement is calculated in sector shape (the sector boundary can use the existing network coverage threshold, that is, RSRP = -110), and the overlap rate of the two sectors is output, so as to identify the cell with abnormal 5G coverage.

[0068] Therefore, the technical solution provided by the embodiment of the present invention can intelligently identify cells with abnormal 5G coverage under the same coverage requirements of a single 4G / 5G cell, thereby providing assistance for quickly discovering cells with abnormal 5G coverage and improving the intelligent operation level of the existing network and user perception.

[0074] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0075] The embodiment of the present invention provides a method for identifying cells with abnormal coverage. Figure 1 As shown, it shows a flowchart of the method for identifying cells with abnormal coverage provided by an embodiment of the present invention, and the method includes the following sub-steps:

[0076] S101, determine a target 4G cell and a target 5G cell with the same coverage requirement.

[0077] In the embodiments of the present invention, considering that in the current 5G network construction process, 5G wireless network equipment is basically directly added to the original 4G site to achieve the same coverage effect as the 4G cell; the height, azimuth and downtilt angle of such 5G cells are mainly configured with reference to the 4G cells, so that single 4G and single 5G cells with the same coverage requirements can be identified from the purpose of the design scheme.

[0078] Therefore, in an embodiment of the present invention, in step S101, a target 4G cell and a target 5G cell with the same coverage requirements can be determined according to the design scheme and network management configuration of the 4G cell and the 5G cell.

[0079] In an embodiment of the present invention, the designed coverage radius and designed coverage sector of the 4G cell and the 5G cell may also be determined according to the design scheme and network management configuration of the 4G cell and the 5G cell.

[0080] In the actual application process of the embodiment of the present invention, in order to improve the accuracy of identifying the cell coverage position (ie, the longitude and latitude reported by the user), analysis may be performed only on pure outdoor base stations.

[0081] S102, obtain the 5G AGPS-MR related to the target 5G cell.

[0082] Among them, the 5G AGPS-MR is the AGPS-MR reported by the 4G cell that has cross-coverage with the target 5G cell.

[0083] In an embodiment of the present invention, 5G cells of 4G cells with the same coverage requirements can be regarded as a group of cell pairs. In practical applications, a group of cell pairs can be arbitrarily selected, and the 5G cell therein can be used as the target 5G cell. The target 5G cell is used as the starting cell to find all 4G cells that have cross-coverage with the designed coverage sector of the 5G cell, and collect AGPS-MRs reported by terminals that have resided in these 4G cells as 5G AGPS-MRs, so as to obtain MRs carrying latitude and longitude information, so as to further analyze and determine the actual coverage range of the 5G cell.

[0084] S103: Acquire a 4G AGPS-MR related to the target 4G cell.

[0085] The 4G AGPS-MR is an AGPS-MR reported by a 4G cell that has cross coverage with the target 4G cell.

[0086] In an embodiment of the present invention, corresponding to step S102, a cell pair can be formed with the target 5G cell, that is, a 4G cell with the same coverage requirement as the target 5G cell can be used as the target 4G cell.

[0087] In the embodiment of the present invention, similar to step S102, the target 4G cell is used as the starting cell, and all 4G cells that have cross-coverage with the designed coverage sector of the 4G cell are searched, and the AGPS-MR reported by the terminals that have resided in these 4G cells are collected as 4G AGPS-MR, so as to further analyze and determine the actual coverage range of the 4G cell.

[0088] In an embodiment of the present invention, the same method is used to obtain the 4G AGPS-MR related to the target 4G cell and the 5G AGPS-MR related to the target 5G cell, so as to avoid errors caused by the analysis method when the actual coverage range of the 4G cell and the 5G cell is subsequently analyzed.

[0089] In the embodiment of the present invention, the AGPS-MR reported by the terminal residing in the target 4G cell may also be directly obtained as the 4G AGPS-MR.

[0090] S104: Determine the coverage sector of the target 5G cell and the coverage sector of the target 4G cell based on the 5G AGPS-MR and the 4G AGPS-MR respectively.

[0091] In an embodiment of the present invention, in order to identify whether a target 5G cell under the same coverage requirement is an abnormal coverage cell, it is necessary to calculate the coverage overlap between the target 4G and target 5G cells under the same coverage requirement.

[0092] In an embodiment of the present invention, the actual signal coverage of 4G and 5G cells is simplified into one or more sector graphics, and the boundary of the sector is determined according to the RSRP value of -110 obtained in the AGPS-MR.

[0093] S105, determining the overlap rate based on the coverage sector of the target 5G cell and the coverage sector of the target 4G cell, and when the overlap rate is less than a preset overlap rate threshold, determining the target 5G cell as a coverage abnormality cell.

[0094] In an embodiment of the present invention, a preset overlap rate threshold can be set according to actual needs. When the overlap rate between the target 5G cell and the target 4G cell is greater than or equal to the preset overlap rate threshold, the target 5G cell is considered to be a normal coverage cell; if it is lower than the preset overlap rate threshold, the target 5G cell is considered to be an abnormal coverage cell.

[0095] Therefore, the technical solution proposed in the embodiment of the present invention can intelligently, quickly and accurately determine the 5G cells with coverage abnormalities, so that technicians can optimize the coverage of the 5G cells through network management parameters and on-site adjustments.

[0096] Based on the above embodiment, in an optional implementation manner of the embodiment of the present invention, step S102 includes the following sub-steps:

[0097] S1021, determine the first 4G cell whose cell location is within the designed coverage radius of the target 5G cell.

[0098] In the embodiment of the present invention, the site location of the target 5G cell can be used as the center of the circle, and its designed coverage radius can be used as the radius of the circle to obtain the maximum coverage range of the target 5G cell, and the 4G cell whose cell location falls within the maximum coverage range can be used as the first 4G cell. Figure 2 As shown, it shows a schematic diagram of the first 4G cell within the coverage radius of the 5G cell design. Figure 2In the figure, the 4G cell position 1 and the 4G cell position 2 are both within a circle with the target 5G cell position as the center point and the target 5G cell coverage radius as the radius. Therefore, Figure 2 The 4G cells corresponding to the two green dots in the figure are the first 4G cells within the designed coverage radius of the target 5G cell.

[0099] In the embodiment of the present invention, the designed coverage radius of each cell is a theoretical coverage radius determined according to its design scheme and network management configuration.

[0100] Specifically, the distance conversion formula can be used to determine whether the 4G cell is within the design coverage radius of the target 5G cell. The distance conversion formula is as follows:

[0101]

[0102] Among them, α1 and α2 represent the latitude of the target 5G cell and the 4G cell to be analyzed. Represents the longitude of the target 5G cell and the 4G cell to be analyzed, and R represents the radius of the earth, which is generally 6371000 meters. Through the above distance conversion formula, the distance between each 4G cell to be analyzed and the target 5G cell can be determined, and the 4G cell to be analyzed whose distance is less than the design coverage radius of the target 5G cell is determined as the first 4G cell within the coverage radius of the target 5G cell.

[0103] In the embodiment of the present invention, the design coverage radius of the target 5G cell is determined according to the design scheme and network management configuration of the 5G cell. The longitude and latitude of the target 5G cell and each 4G cell to be analyzed are also determined according to the construction location in the design scheme.

[0104] S1022, determine a second 4G cell whose cell location is outside the designed coverage radius of the target 5G cell and has an overlapping coverage area with the target 5G cell.

[0105] In the embodiment of the present invention, it is considered that in addition to the cells whose cell locations are within the coverage radius of the target 5G cell, there is also a second 4G cell whose cell location is outside the coverage radius of the 5G cell, but the cell coverage direction is toward the 5G cell location, and there is an overlapping coverage area with the target 5G cell. Figure 3 As shown, it shows a schematic diagram of a 4G cell being outside the designed coverage radius of a 5G cell and having a cross-coverage area. Figure 3 In the figure, the green dot is the location of the 4G cell to be analyzed, the red dot is the location of the target 5G cell, the green solid arrow indicates the design coverage radius of the 4G cell to be analyzed, the red solid arrow indicates the design coverage radius of the target 5G cell, the green solid arc is the schematic diagram of the coverage sector boundary of the 4G cell, and the red solid arc is the schematic diagram of the coverage sector boundary of the 5G cell. Figure 3 It can be seen that there is an area where the two arcs intersect each other, so it can be considered that the 4G cell is a 4G cell that has overlapping coverage with the target 5G cell, except for the cell whose cell location is within the coverage radius of the target 5G cell.

[0106] In the embodiment of the present invention, the second 4G cell may be identified based on a cell cross search method. Specifically, step S1022 may include the following sub-steps:

[0107] S10221, based on the target 5G cell location point and designed coverage radius, as well as the location point and designed coverage radius of the 4G cell to be analyzed, determine whether there are two first intersection points between the circles where the designed coverage sectors of the target 5G cell and the 4G cell to be analyzed are located.

[0108] Specifically, in an embodiment of the present invention, the coverage range of the target 5G cell and the 4G cell to be analyzed are defined as a sector-shaped area. For a 4G cell whose longitude and latitude are outside the target 5G design coverage sector, as long as there is overlap between the 5G cell and the 4G cell coverage sector, this 4G cell is considered to be a valid 4G cell around the target 5G cell.

[0109] Specifically, firstly, it is analyzed whether there are intersections between the two circles where the sector curve of the coverage sector of the target 5G cell and the sector curve of the coverage sector of the 4G cell to be analyzed are located. The specific expression is as follows:

[0110]

[0111] Among them, a coordinate system is established with the target 5G cell as the coordinate origin, R is the design coverage radius of the target 5G cell; x0 and y0 are the longitude and latitude of the 4G cell to be analyzed in the coordinate system; r is the design coverage radius of the 4G cell to be analyzed, and it is calculated whether there are two first intersections in the equation group. If there is no first intersection or only one first intersection, it means that the 4G cell to be analyzed is not a valid 4G cell around the target 5G cell.

[0112] Specifically, when there are two first intersection points, perform the following steps:

[0113] S10222, take the curve segment intercepted by the circle where the 5G cell design coverage sector curve between the two first intersection points is located as the first curve segment.

[0114] In the embodiment of the present invention, the designed coverage sector of each cell is a theoretical coverage sector determined according to the design scheme of the cell and the network management configuration.

[0115] In the embodiment of the present invention, the designed coverage sector corresponding to a cell may be composed of one or more sectors, or may be a circular coverage area.

[0116] Specifically, Figure 3 As shown, there are two first intersections between the green solid arc and the red solid arc. The red arc segment between the two first intersections (the arc segment between the two first intersections close to the 4G cell to be analyzed) is used as the first curve segment S1.

[0117] S10223, determine the two second intersection points of the two straight edges of the 4G cell design coverage sector to be analyzed and the circle where the 5G cell design coverage sector curve is located, and use the curve segment intercepted by the two second intersection points on the circle where the 5G cell coverage sector curve is located as the second curve segment S2.

[0118] like Figure 3 As shown, the sector-shaped area composed of two green dotted arrows and the corresponding green solid arcs is a schematic diagram of the coverage sector of the 4G cell to be analyzed, the two intersection points of the two green dotted arrows and the red solid arc are the second intersection points, and the red arc segment between the two second intersection points (the arc segment close to the 4G cell to be analyzed) is the second curve segment.

[0119] S10224, design the 5G cell coverage sector curve segment as the third curve segment.

[0120] like Figure 3 As shown, the sector area composed of two red dotted arrows and the corresponding red solid arc is a schematic diagram of the coverage sector of the target 5G cell, and the red arc segment between the two red dotted arrows is the third curve segment S3.

[0121] S10225: When there are repeated parts among the first curve segment, the second curve segment and the third curve segment, the 4G cell to be analyzed is determined to be the second 4G cell.

[0122] In the embodiment of the present invention, based on Figure 3 It can be seen that when there is a common overlapping part among the first curve segment, the second curve segment and the third curve segment, it indicates that there is an overlapping part between the designed coverage sectors of the 4G cell to be analyzed and the target 5G cell. Then, when there is an overlapping part among the first curve segment, the second curve segment and the third curve segment, the corresponding 4G cell to be analyzed can be determined as the second 4G cell, that is, a 4G cell located outside the designed coverage radius of the target 5G cell and having an overlapping coverage area with the target 5G cell.

[0123] S1023: Determine the 5G AGPS-MR based on the first 4G cell and the AGPS-MR reported in the first 4G cell.

[0124] In an embodiment of the present invention, based on the relationship between the coverage radius of the 4G cell to be analyzed and the target 5G cell, the cell cross-search method can comprehensively determine all 4G cells that have cross-coverage with the target 5G cell, and these 4G cells are used as valid 4G cells related to the target 5G cell. In the subsequent analysis process, the AGPS-MR reported by these valid 4G cells is used as the 5G AGPS-MR of the target 5G cell, which is used to analyze the actual coverage area of ​​the target 5G cell.

[0125] Based on the above embodiment, in an optional implementation manner of the embodiment of the present invention, the method further includes the following steps:

[0126] S1: Use the AGPS-MR reported in the first 4G cell and the second 4G cell as 5G MR sampling points.

[0127] S2, calculate the Euclidean distance between the 5G MR sampling point and the target 5G cell location point.

[0128] S2: When the Euclidean distance minus the coverage radius of the target 5G cell is greater than a preset distance threshold, the corresponding 5G MR sampling point is removed.

[0129] S4, determining the 5G AGPS-MR based on the remaining 5G MR sampling points.

[0130] In the embodiment of the present invention, in order to improve the accuracy of the prediction result, it is further proposed to analyze the AGPS-MR reported by the first 4G cell and the second 4G cell. Specifically, each reported AGPS-MR can be used as a 5G MR sampling point.

[0131] These 5G MR sampling points are processed to eliminate outliers. The specific processing method is to calculate the Euclidean distance between each 5GMR sampling point and the target 5G cell location point (which can be expressed as longitude and latitude). If the Euclidean distance minus the coverage radius of the target 5G cell is greater than the preset distance threshold, the 5G MR sampling point is eliminated.

[0132] In the embodiment of the present invention, the preset distance threshold can be determined by a technician according to actual needs. For example, the preset distance threshold can be 1500m, and the expression method for removing abnormal values ​​can be shown as follows:

[0133] |Distance((x NRCELL ,y NRCELL ),(x MR ,y MR ))-distance NRCELL |≤1500m (3)

[0134] Among them, x NRCELL,y NRCELL Indicates the longitude and latitude of the target 5G cell, x MR ,y MR Represents the longitude and latitude of the 5G MR sampling points reported by the first 4G cell and the second 4G cell, distance NRCELL represents the designed coverage radius of the target 5G cell. Finally, according to the conversion formula between longitude and latitude and distance shown in formula (1), the distance between the MR sampling point and the target 5G cell can be obtained.

[0135] In the embodiment of the present invention, by excluding 5G MR sampling points of 4G cells that are too far away from the 5G boundary, the interference of isolated 5G MR sampling points on the final result can be reduced, thereby improving the prediction accuracy.

[0136] In the embodiment of the present invention, in the process of determining the 4G AGPS-MR of the target 4G cell, a method similar to that of determining the 5G AGPS-MR of the target 5G cell may be adopted. Specifically, a method similar to the above steps S1021 to S1023 may be adopted. Specifically, based on the above steps S1021 to S1023, the target 5G cell is replaced with the target 4G cell, and based on formula (1), the longitude and latitude of the target 5G cell are replaced with the longitude and latitude of the target 4G cell, and the design coverage radius of the target 5G cell is replaced with the design coverage radius of the target 4G cell. In this way, the 4G cell to be analyzed whose distance is less than the design coverage radius of the target 4G cell can be determined as the third 4G cell within the coverage radius of the target 4G cell.

[0137] Based on formula (2), the target 5G cell is replaced by the target 4G cell, a coordinate system is established with the target 4G cell as the coordinate origin, and the design coverage radius of the target 5G cell is replaced by the design coverage radius of the target 4G cell. Thus, it can be determined whether there is a fourth 4G cell around the target 4G cell whose cell coordinates are outside the target 4G design coverage sector but overlap with the target 4G cell coverage sector.

[0138] Based on formula (3), the longitude and latitude of the target 5G cell are replaced with the longitude and latitude of the target 4G cell, and the 4G MR sampling points of the 4G cells that are too far from the boundary of the target 4G cell are excluded according to the longitude and latitude of the 4G MR sampling points reported by the third 4G cell and the fourth 4G cell.

[0139] Based on the above embodiment, in an optional implementation manner of the embodiment of the present invention, the S104 includes the following sub-steps:

[0140] S1041, determine the coverage sector of the 5G cell according to the location information carried by each of the 5G AGPS-MRs, and determine the boundary of the coverage sector according to the 5G AGPS-MR corresponding to the RSRP equal to the preset value.

[0141] S1042, determining the coverage sector of the 4G cell according to the location information carried by each of the 4G AGPS-MRs, and determining the boundary of the coverage sector according to the 4G AGPS-MR corresponding to the RSRP being equal to the preset value.

[0142] In the embodiment of the present invention, based on step S102, the 5G AGPS-MR of the target 5G cell can be obtained, and the 5G AGPS-MR is jointly analyzed. The specific representation is as follows:

[0143] ∏ MR =MR 5G MR 5G ∈(cell LTE ) (4)

[0144] Among them, MR 5G ∈(cell LTE ) indicates that the 5G AGPS-MR comes from the first 4G cell or the second 4G cell. MR Represents the reported 5G MR, which has resided in the LTE cell (the first 4G cell and the second 4G cell) and has longitude and latitude.

[0145] In the embodiment of the present invention, since there are more than one first 4G cell and second 4G cell related to the target 5G cell, in the embodiment of the present invention, the MR sampling points can be classified according to different 4G cells, the MR sampling points belonging to the first 4G cell and the second 4G cell can be quickly identified, and the complexity of the prediction algorithm is reduced.

[0146] In the embodiment of the present invention, based on step S103, the 5G AGPS-MR of the target 4G cell can be obtained, and the 4G AGPS-MR is jointly analyzed. The specific expression is similar to the above formula (4), and the 4G MR with longitude and latitude reported by the terminal that has resided in the LTE cell (the third 4G cell and the fourth 4G cell) is jointly analyzed.

[0147] In the embodiment of the present invention, since there are more than one third 4G cell and fourth 4G cell related to the target 4G cell, in the embodiment of the present invention, the MR sampling points can be classified according to different 4G cells, the MR sampling points belonging to the third 4G cell and the fourth 4G cell can be quickly identified, and the complexity of the prediction algorithm is reduced.

[0148] Based on the above embodiment, in an optional implementation of the embodiment of the present invention, S105 includes the following sub-steps:

[0149] S1051, determine the overlapping area between the coverage sector of the target 5G cell and the coverage sector of the target 4G cell.

[0150] S1052, determine the total coverage area of ​​the coverage sector of the target 5G cell and the coverage sector of the target 4G cell.

[0151] S1053: Determine an overlap rate based on the overlap area and the total coverage area.

[0152] In an embodiment of the present invention, in order to identify whether the target 5G cell under the same coverage requirement is an abnormal coverage cell, the actual coverage conditions of the target 5G cell and the target 4G cell under the same coverage requirement are analyzed based on steps S101 to S104.

[0153] In the embodiment of the present invention, the signal coverage of the 4G and 5G cells can be simplified into a sector graph, the sector boundary adopts the RSRP value of -110 (specifically, the actual threshold of the existing network coverage calculation can be adopted), and then the overlap rate of the 4G and 5G cell coverage sector graphs is calculated, so as to determine whether the 5G cell is a cell with abnormal coverage. The specific formula is as follows:

[0154] O=(Four area ∩Five area ) / (Four area ∪Five area )

[0155] Among them, Four area is a two-dimensional sector of the target 4G cell with the same coverage (the 4G MR information is obtained in step S103, and the sector description is performed based on the 4G MR information here), Five area is a two-dimensional sector of the target 5G cell with the same coverage (the 5G MR information is obtained in step S102, and the sector is described here based on the 5G MR information); O refers to the overlap rate. When the 4G coverage sector and the 5G coverage sector completely overlap, the overlap rate is 100%, and when they are completely separated, the overlap rate is 0%.

[0156] In an embodiment of the present invention, the preset overlap rate threshold may be 90%. When the overlap rate is greater than or equal to 90%, the target 5G cell is considered to be a normal coverage cell; and when the overlap rate is lower than 90%, the target 5G cell is considered to be an abnormal coverage cell.

[0157] In the embodiment of the present invention, firstly, a single 4G / 5G cell that needs to meet the same coverage requirement is identified through the design and construction plan. In the embodiment of the present invention, considering that the MR (Measurement Report) reported by the 5G cell does not have longitude and latitude information, it is impossible to directly present and analyze the coverage of the 4G and 5G cells on the map; based on this, the embodiment of the present invention proposes to use the MR with AGPS (Assisted Global Satellite Positioning System) information reported by the 4G cell for subsequent analysis. Specifically, in order to identify the 4G cell where the AGPS-MR of the target 5G cell may exist, the embodiment of the present invention adopts the 5G cell coverage distance and cell cross search method for identification; and removes the 5G MR sampling points reported by the isolated terminal in the 4G cell by the distance from the 5G AGPS-MR reported by the 4G cell (in the embodiment of the present invention, the AGPS-MR reported by the 4G cell that may be in the same coverage area as the 5G cell is regarded as the 5G AGPS-MR) to the target 5G cell, thereby obtaining the effective 5G AGPS-MR reported by the 4G cell. The method for obtaining the effective 4G AGPS-MR reported by the 4G cell is basically the same as the method for obtaining the effective 5G AGPS-MR reported by the 4G cell. Finally, the coverage of the single 4G / 5G cell with the same coverage requirement is calculated in sector shape (the sector boundary uses the existing network coverage threshold, that is, RSRP = -110), and the overlap rate of the two sectors is output, so as to identify the cell with abnormal 5G coverage.

[0158] Therefore, the technical solution provided by the embodiment of the present invention can intelligently identify cells with abnormal 5G coverage under the same coverage requirements of a single 4G / 5G cell, thereby providing assistance for quickly discovering cells with abnormal 5G coverage and improving the intelligent operation level of the existing network and user perception.

[0187] Based on the overlap area and the total coverage area, an overlap ratio is determined.

[0188] First, a single 4G / 5G cell that needs to meet the same coverage requirements is identified through the design and construction plan. In the embodiment of the present invention, considering that the MR (Measurement Report) reported by the 5G cell does not have longitude and latitude information, it is impossible to directly present and analyze the coverage of the 4G and 5G cells on the map; based on this, the embodiment of the present invention proposes to use the MR with AGPS (Assisted Global Positioning System) information reported by the 4G cell for subsequent analysis. Specifically, in order to identify the 4G cell where the AGPS-MR of the target 5G cell may exist, the embodiment of the present invention adopts the 5G cell coverage distance and cell cross search method for identification; and the 5G AGPS-MR reported by the 4G cell (in the embodiment of the present invention, the AGPS-MR reported by the 4G cell that may be in the same coverage area as the 5G cell is regarded as the 5G AGPS-MR) is removed from the 5G MR sampling points reported by the isolated terminal in the 4G cell, thereby obtaining the effective 5G AGPS-MR reported by the 4G cell. The method for obtaining the effective 4G AGPS-MR reported by the 4G cell is basically the same as the method for obtaining the effective 5G AGPS-MR reported by the 4G cell. Finally, the coverage of the single 4G / 5G cell with the same coverage requirement is calculated in sector shape (the sector boundary uses the existing network coverage threshold, that is, RSRP = -110), and the overlap rate of the two sectors is output, so as to identify the cell with abnormal 5G coverage.

[0189] Therefore, the technical solution provided by the embodiment of the present invention can intelligently identify cells with abnormal 5G coverage under the same coverage requirements of a single 4G / 5G cell, thereby providing assistance for quickly discovering cells with abnormal 5G coverage and improving the intelligent operation level of the existing network and user perception.
