These drawings and the written description are not intended to restrict the scope of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0127] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. Unless otherwise indicated, the same numbers on different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments are not meant to represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0128] Daily mobile network problems are mainly found by professional technicians through testing, but manual network problem judgment needs to consume a lot of time and energy, and when the network problem scale is large, manual judgment can become very difficult and time-consuming. On the other hand, different technicians may make judgments according to different experiences and standards when judging network problems, so that the judgment results lack consistency. In view of the problems of low efficiency and lack of consistency in traditional manual network problem judgment, the present application designs a wireless network problem diagnosis method, acquires a target grid to which a to-be-monitored position belongs, judges network problems existing in the target grid according to an MDT sampling point proportion and MDT data of a cell covering the target grid, saves the time of network problem diagnosis, and improves the network problem discovery efficiency.

[0129] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0130] Figure 1 The wireless network problem diagnosis method flow provided by the embodiment of the present application Figure One As shown in the figure, the method comprises: Figure 1

[0131] S101, acquiring the latitude and longitude information of a to-be-detected position, and matching a target grid in a plurality of grids included in a current area according to the latitude and longitude information of the position, the position being located in the target grid;​

[0132] In this embodiment, when judging the wireless network problem of the to-be-monitored position, the latitude and longitude information of the to-be-monitored position needs to be acquired first, and the grid to which the to-be-monitored position belongs is matched in a plurality of grids in the current area according to the latitude and longitude information of the to-be-monitored position. For example, the area where the user is located is a playground, which is divided into a plurality of grids, and each grid is a 50m*50m sub-area. When performing wireless network problem diagnosis, the target grid to which the user position belongs can be screened from the plurality of grids of the playground according to the latitude and longitude of the user.

[0133] S102, acquiring MDT data of an MDT sampling point of the target grid, the MDT data carrying a target number of collection information obtained by sampling at different times, the collection information including a cell identifier, a grid number, and a cell coverage level;

[0134] MDT (Minimization of Drive-Tests) is a technology for automatically collecting terminal position measurement data through a terminal to realize automatic test data collection. An MDT sampling point is a place where terminal position measurement data is collected through MDT technology. MDT data refers to terminal position measurement data collected through MDT technology, including the latitude and longitude of the terminal, signal strength, and other parameters, which are used to evaluate network quality and solve network problems. In this embodiment, the user terminal is in the target grid, and the MDT technology is used to sample at the to-be-monitored position at a preset time interval to obtain MDT data of the target grid at different times. Specifically, the MDT data carries a target number of collection information obtained by sampling at different times, and each collection information includes a cell identifier, a grid number, and a cell coverage level. For example, when MDT sampling is performed, the user terminal occupies the signal of cell A at this time, and the collection information of this time includes the cell identifier of cell A, the grid number of the target grid, and the cell coverage level of cell A in the target grid. Similarly, MDT sampling is performed at a preset time interval in the target grid to obtain a target number of collection information, and finally the MDT data collected by the user terminal is obtained.

[0135] S103, according to the MDT data, acquiring a sampling point proportion of an actual number of collection information of each cell covering the target grid to the target number;

[0136] The MDT data includes a plurality of collection information, each of which includes a cell identifier occupied by the user terminal when performing MDT sampling. The proportion of sampling points of each cell covering the target grid is obtained according to the proportion of the actual number of collection information of each cell covering the target grid in the target number. Specifically, the actual number of collection information of each cell can be calculated according to the cell identifier in all collection information, and then the proportion of sampling points of each cell is obtained by dividing the actual number of collection information of each cell by the target number.

[0137] In S104, whether the target grid has a network problem is determined according to the proportion of sampling points of each cell covering the target grid and the MDT data. The network problem includes a network coverage problem and / or a service awareness problem.

[0138] Further, whether the target grid has a network problem is determined according to the proportion of sampling points of each cell covering the target grid and the MDT data. In this embodiment, the network problem includes a network coverage problem and / or a service awareness problem. Specifically, the network coverage problem is mainly related to the network signal coverage range, involving the configuration and performance of devices such as base stations, antennas, and feeder lines; the service awareness problem is mainly related to the user's experience of using network services, involving the quality, stability, and availability of the network. For example, the cell with the highest proportion of sampling points can be taken as the main coverage cell of the target grid, and whether the target grid has a network problem is determined according to the cell coverage level of the main coverage cell in the target grid. If there is a network problem, the type of network problem of the target grid can be determined according to the distance of the target grid from the main coverage cell. If the distance of the target grid from the main coverage cell exceeds a certain threshold, the type of network problem of the target grid is determined as a network coverage problem. On the other hand, the service awareness problem of the target grid can be determined according to the online experience of the user terminal, such as the video download rate.

[0139] The wireless network problem diagnosis method provided in the embodiment comprises the steps of: obtaining the longitude and latitude information of a position to be detected; matching a target grid in a plurality of grids included in a current area according to the longitude and latitude information of the position, wherein the position is located in the target grid; obtaining MDT data of MDT sampling points of the target grid, wherein the MDT data carries a target number of collection information obtained at different times, and the collection information comprises a cell identifier, a grid number and a cell coverage level; obtaining a sampling point proportion of an actual number of collection information of each cell covering the target grid relative to the target number according to the MDT data; and judging whether the target grid has a network problem according to the sampling point proportion of each cell covering the target grid and the MDT data, wherein the network problem comprises a network coverage problem and / or a service awareness problem. The method provided in the embodiment realizes automatic diagnosis of a grid-level wireless network in terms of service awareness and network coverage, improves the efficiency of network problem discovery, and saves labor costs.

[0140] Figure 2 The wireless network problem diagnosis method provided in the embodiment Figure Two . As shown in Figure 2 , the embodiment is based on the above-mentioned embodiment and details the network coverage problem diagnosis process.

[0141] S201, sorting the sampling point proportions of the plurality of cells in descending order to obtain a plurality of target cells in the top N and the arrangement order of the N target cells, wherein the N is a positive integer;

[0142] In the embodiment, after obtaining the sampling point proportions of each cell covering the target grid, the sampling point proportions of all cells are sorted in descending order to obtain a descending sequence of the sampling point proportions of all cells covering the target grid, and then the plurality of target cells in the top N and the arrangement order of the N target cells are obtained according to actual requirements. For example, there are 10 cells covering the target grid, and the 10 cells are sorted in descending order according to the sampling point proportions, and then the top 3 cells are obtained as the target cells.

[0143] S202, obtaining a first cell in the top position according to the arrangement order of the N target cells, and judging whether the sampling point proportion of the first cell is greater than a first preset threshold value, if yes, performing S203, and if no, performing S207;

[0144] Further, for the N target cells, the cell ranked first is taken as a first cell, and then it is judged whether the sampling point proportion of the first cell is greater than a first preset threshold. The first preset threshold can be set to 60%. If the sampling point proportion of the first cell is greater than the first preset threshold, it is considered that the influence of the first cell on the target grid is large, and then the network coverage type problem can be further judged through the cell coverage level of the first cell or the distance between the first cell and the target grid. If the sampling point proportion of the first cell is not greater than the first preset threshold, S207 is performed.

[0145] S203, it is judged whether the cell coverage level of the first cell is greater than a second preset threshold. If yes, the target grid has no network coverage type problem; if no, S204 is performed.

[0146] S204, it is judged whether the distance between the target grid and the first cell is greater than a first preset distance. If yes, S205 is performed; if no, S206 is performed.

[0147] S205, it is determined that the target grid has a network coverage type problem, and the network coverage type problem is specifically a base station lack problem.

[0148] S206, it is determined that the target grid has a network coverage type problem, and the network coverage type problem is specifically an antenna feeder problem.

[0149] The cell coverage level refers to the level value of the signal strength of the cell base station covering the target grid. Whether the cell coverage level of the first cell is greater than the second preset threshold can judge whether the cell coverage level of the first cell in the target grid reaches a certain strength. If the cell coverage level of the first cell is greater than the second preset threshold, it is considered that the target grid has no network coverage type problem. If the cell coverage level of the first cell is not greater than the second preset threshold, it is considered that the target grid has a network coverage type problem, and the type of the network coverage type problem needs to be further confirmed. In the specific implementation process, whether the distance between the target grid and the first cell is greater than the first preset distance can judge whether the distance between the target grid and the first cell is too far. If the distance between the target grid and the first cell is greater than the first preset distance, it is considered that the distance between the target grid and the first cell is too large, that is, the target grid lacks a base station, and then it is considered that the network coverage type problem of the target grid is specifically a base station lack problem. If the distance between the target grid and the first cell is not greater than the first preset distance, it is considered that the target grid does not lack a base station, but the cell coverage level of the first cell does not meet the condition, and it is possible that the antenna feeder of the first cell has a problem, which needs to be checked and optimized. Then, it is considered that the target grid has a network coverage type problem and the network coverage type problem is specifically an antenna feeder problem.

[0150] S207, according to the arrangement order of the N target cells, a second cell ranked second is obtained.

Further, according to the sampling point proportions of each cell covering the target grid, a level weight value of each cell is obtained. Since the higher the cell sampling point proportion, the greater the influence of the cell on the target grid, therefore, the value of the sampling point proportion of each cell can be taken as the level weight value. For example, among the cells covering the target grid, the sampling point proportion of A cell is 30%, and the level weight value of A cell is 30%. Then, according to the cell coverage level of each cell and the corresponding level weight value, weighted summation is performed to finally obtain the target level of the target grid.

[0170] In the implementation process, after the target level of the target grid is acquired, it is judged whether the target level is higher than the fourth preset threshold, if the target level is higher than the fourth preset threshold, it is considered that the cell signal of the target grid is relatively chaotic, the coverage of the target grid may be uneven, and the user may encounter a weak signal or no signal when communicating, resulting in unstable communication, therefore, network optimization is needed, for example, the received signal can be filtered, denoised, enhanced and the like, so as to reduce or eliminate the influence of interference, noise and other adverse factors, so as to obtain clearer and purer signal.

[0171] If the target level is not higher than the fourth preset threshold, the target distance between the cell closest to the target grid and the target grid is acquired, it is judged whether the target distance is greater than the second preset distance, if yes, it is considered that the cell closest to the target grid is too far from the target grid, that is, the target grid lacks a base station, and the network coverage problem of the target grid is specifically a base station lacking problem.

[0172] It should be noted that, in order to better illustrate the technical scheme, the number of target cells in the method provided in the embodiment is 3, however, it should be emphasized that the embodiment is only for the convenience of understanding, and does not represent the specific situation in the actual operation process, in the actual operation process, the number of target cells can be changed according to the actual situation and specific needs.

[0173] The wireless network problem diagnosis method provided in the embodiment gradually judges the network problem of the target grid according to the proportion of the sampling point of the target cell, further judges the specific network problem type of the target grid according to the level of the target cell and the distance from the target grid, and the specific network problem type includes a base station lacking problem or a feeder problem. The method provided in the embodiment realizes the automation of the type determination of the wireless network problem, accurately determines the type of the network problem, improves the diagnosis speed of the wireless network problem, and saves the time of discovering the network problem.

[0174] Figure 3 is the wireless network problem diagnosis method flow provided in the embodiment of the application Figure Three . As Figure 3As shown, the embodiment on the basis of the above embodiment, the service awareness type problem diagnosis process is explained in detail.

[0175] S301, according to the sampling point proportion of each cell covering the target grid, determine the weight of each cell for the service awareness index;

[0176] S302, for each service awareness index, according to the service awareness index value and the corresponding weight of each cell, the weighted value of the service awareness index is obtained.

[0177] In the embodiment, the service awareness index is an index for measuring and evaluating network service performance, including per cell TCP three handshake delay, RTT delay, Web response success rate, video download rate and other indexes. In the specific implementation process, according to the sampling point proportion of each cell covering the target grid, the weight of each cell for the service awareness index is determined, wherein the greater the sampling point proportion, the greater the influence of the corresponding cell on the target grid, therefore, when determining the weight of each cell for the service awareness index, the sampling point proportion can be used as the weight of the corresponding cell for the service awareness index. For example, if the sampling point proportion of B cell is 60%, the weight of the service awareness index of B cell is 60%. Further, for each service awareness index, according to the service awareness index value and the corresponding weight of each cell, the weighted value of the service awareness index is obtained. Exemplarily, the cells covering the target grid are C cell and D cell, wherein the sampling point proportion of C cell is 60%, the sampling point proportion of D cell is 30%, for the TCP three handshake delay, the TCP three handshake delay of C cell and D cell is obtained respectively, then the TCP three handshake delay of C cell and D cell is weighted and summed with the corresponding sampling point proportion, the weighted value of the TCP three handshake delay of the target grid is obtained.

[0178] S303, for a plurality of service awareness indexes, it is judged whether there is a target awareness index that does not meet the preset condition, wherein each service awareness index corresponds to a respective preset condition; if there is, S304 is executed, if there is not, the target grid has no service awareness type problem;

[0179] In the specific implementation process, after weighting and summing each index of the target grid, the weighted value of all indexes is obtained, it is judged whether there is an index weighted value that does not meet the preset condition, wherein each service awareness index corresponds to a respective preset condition. If all service awareness indexes meet the respective preset conditions, the target grid has no service awareness type problem, if there is a target awareness index that does not meet the preset condition, it means that the target grid has network problem, which needs to be further judged.

[0180] S304, acquiring a fourth cell with the highest proportion of sampling points according to the proportion of sampling points of each cell of the target grid;

[0181] Specifically, a cell with the highest proportion of sampling points of cells covering the target grid is selected as the fourth cell, and then the coverage information of the fourth cell is acquired, including at least one of the cell coverage level, the load, and the interference of the fourth cell. The load refers to the number of users or the processing capacity of network equipment in the cell. If the load is too large, it may cause network congestion, disconnection, and other problems. The interference refers to the mutual superposition and interference of signals of multiple cells, resulting in a decrease in signal quality.

[0187] S308, determining whether the neighboring cell interference is high interference, if yes, performing S309, if no, performing S310;

[0188] S309, determining that the target grid has a service awareness type problem, and the service awareness type problem is specifically an interference troubleshooting problem;

[0189] If the load of the fourth cell is not higher than the preset load, it is further determined whether the neighboring cell interference of the fourth cell is high interference, if it is high interference, it is determined that the target grid has a service awareness type problem, and the service awareness type problem is specifically an interference troubleshooting problem, if it is not high interference, further determination is performed.

[0190] S310, determining whether there is PCI interference, if there is PCI interference, the service awareness type problem is a PCI modification problem, if there is no PCI interference, other problem checking is performed.

[0191] If the above adjacent cell interference is not high interference, it is determined whether the fourth cell has PCI interference. The PCI interference is also called PCI mod 3 interference or mod 3 conflict, which is a common same frequency interference in the 4G network construction using FDD-LTE same frequency networking mode. It occurs when two or more adjacent cells use the same PCI mod 3, which can cause two or more reference signals to appear at the same time and at the same frequency location, thereby causing mutual interference of the reference signals and causing inaccurate channel measurement and other problems. If there is PCI interference, it is determined that the target grid has a service awareness type problem, and the service awareness type problem is a PCI modification problem, if there is no PCI interference, other problem checking is performed.

[0192] S311, determining whether the distance between the fourth cell and the target grid is greater than a third preset distance, if yes, performing S312, if no, performing S313;

[0193] S312, determining that there is a network coverage type problem, and the network coverage type problem is specifically a base station lack problem;

[0194] S313, determining that there is a network coverage type problem, and the network coverage type problem is specifically a sky feeder problem.

[0195] If the cell coverage level of the fourth cell is not higher than a fifth preset threshold, it indicates that the signal of the target grid is weak, and there may be a network coverage type problem. It is determined whether the distance between the fourth cell and the target grid is greater than a third preset distance, so as to determine the specific network coverage type problem. If the distance between the fourth cell and the target grid is greater than the third preset distance, it is considered that there is a lack of base station near the target grid, and the target grid has a network coverage type problem, and the network coverage type problem is specifically a base station lack problem. If the distance between the fourth cell and the target grid is not greater than the third preset distance, it is considered that there is no lack of base station near the target grid, and it is determined that there is a network coverage type problem, and the network coverage type problem is specifically a sky feeder problem.
