Based on the system, the method for determining the position information can be executed by the terminal or the server, and can also be realized by the interaction of the terminal and the server. As shown in fig. 1, the method specifically includes:

s110, problem road section optimization is carried out based on the obtained multi-source network data, and a problem road section library is established.

The multi-source network data represents data related to a mobile network from a plurality of data sources, and specifically comprises: drive test data, backstage management data, MR data and signaling data, the concrete effect of corresponding data is:

the drive test is one of the main means for mobile operators to know the condition of the mobile network, and the drive test data covers scenes such as grids, key roads, trunk roads, VIPs, key areas and the like, and contains various objects under different scenes. The drive test data contains rich network indexes, so that the network pulse taking can be realized, the network can be deeply analyzed, the problems of the network are combed out, the fault reasons are analyzed, and the optimization direction is determined;

In this embodiment, the multi-source network data records the network status with abundant data, and the network fault problem can be found by screening according to a certain rule based on the multi-source network data, and further the problem road section is located, and then the optimization analysis is performed on the network fault problem of the problem road section, wherein the network fault problem is found mainly based on the drive test data, and the optimization analysis is often performed on the basis of a certain experience for general setting. The problem road section library is a database which takes the problem road section as a core and is used for recording the optimization analysis process of the network fault problem.

And S120, receiving a network optimization work order, and matching the problem road section library according to the network optimization work order to extract an optimization record of a corresponding problem road section.

The network optimization work order is a work order for requesting network optimization, and is usually a work order generated by a user according to actual network optimization requirements, or a work order generated by a system automatically detecting that network optimization requirements exist, which is not limited herein. The core content in the network optimization work order is a description about a network failure problem, such as failure time, location, performance, range, and the like, and may also include some other information, for example, the network optimization work order issued by the user may also include user identity information and the like. In the embodiment, after the system detects the network optimization work order, the system extracts information related to the network fault problem in the network optimization work order, and further matches location related information in the related information with a problem road section of the problem road section library, so as to locate a corresponding problem road section, where the corresponding problem road section indicates a problem road section to which a location in the network optimization work order, which needs to be subjected to network optimization, belongs, and after the corresponding problem road section is determined, a corresponding optimization record in the problem road section library can be called, where the optimization record records network fault problems, corresponding optimization methods, optimization effects, and the like, which are historically appeared on the corresponding problem road section, so as to facilitate subsequent use as optimization references.

And S130, optimizing the network based on the network optimization work order and the optimization record.

In step S120, the optimization record of the corresponding problem road segment in the problem road segment library has been found according to the network optimization work order, and the network optimization work order records the network fault problem occurring at the corresponding problem road segment currently, and for the mobile network, under the condition that hardware devices such as a base station and the like are not changed, the change of the network condition is traceable, so the optimization record has an important meaning for processing the network fault problem in the network optimization work order. In this embodiment, when processing the network optimization work order, it is usually analyzed whether the same problem (referred to as a network failure problem) occurs in the optimization record, and if the same problem occurs, an optimization scheme is specified with reference to an optimization method and an optimization effect performed on the problem in the optimization record, and the optimization scheme is executed to perform network optimization.

According to the network optimization method provided by the embodiment, the multi-source network data are obtained firstly, problem road section optimization is carried out based on the obtained multi-source network data, the problem road section library is established, then the optimization records corresponding to the problem road sections are extracted according to the received network optimization work order matching problem road section library, and finally the network optimization work order is analyzed by referring to the optimization records to carry out network optimization.

Example two

The second embodiment provides a network optimization method, which can be implemented on the basis of the first embodiment, and further supplements the content in the first embodiment, specifically including:

as shown in fig. 2, the process of establishing the problem road segment library in the network optimization method provided in this embodiment includes steps S111 to 114:

and S111, acquiring multi-source network data including drive test data, background management data, MR data and signaling data.

And S112, positioning the problem road section based on the drive test data.

Abundant network indexes are collected based on the coverage grids in the drive test data, so that the network pulse taking can be realized, the network can be deeply analyzed, the network problems are combed out, the failure reasons are analyzed, and the optimization direction is determined. In some embodiments, step S112 specifically includes steps S1121-1122 (not shown):

s1121, determining a degradation index based on the drive test data, and positioning a road section to be selected corresponding to the degradation index.

The method includes the steps of recording detected location, time and index information in the road test data, rasterizing the road test data (actually obtained log data), analyzing indexes, identifying degraded indexes (RSRP, SINR, MOS, download rate, 5G residence ratio and the like), and identifying a corresponding road section as a problem road section according to a certain rule, such as index degradation meeting a continuous preset distance or index degradation meeting a continuous preset duration.

And S1122, merging based on the road sections to be selected to obtain the problem road sections.

In all the problem road section sets, problem road sections with the distance between the problem road sections smaller than the distance threshold or the time interval smaller than the time threshold are merged, and the purpose is to merge and analyze similar problems.

And S113, analyzing the problem root cause of the drive test data, the background management data, the MR data and the signaling data based on the problem road section.

Specifically, in some embodiments, the process of locating the problem root includes steps S1131 to 1132 (not shown):

s1131, performing data preprocessing on the drive test data, the background management data, the MR data and the signaling data to determine network associated data.

The preprocessing of the drive test data is to analyze first network associated data from the drive test data, and comprises the following steps: KPI indicator change data, scheduling data, signaling data, event data (RRC reestablishment event, handover event, fast decay event), intersystem handover data, intra-system handover data.

The preprocessing of the MR data and the signaling data comprises the steps of performing correlation backfill on MR and S1mme on user information such as IMIS and the like, backfilling longitude and latitude and rasterized position information by adopting a fingerprint positioning method or other methods, performing convergence statistics of various dimensions such as users, cells, grids, road sections and the like on the backfilled MR data, analyzing the change of indexes in the aspect of time and space, and confirming the range and duration of problem influence so as to obtain second network correlation data.

The preprocessing of the data of the background management system is used for extracting the data of the background management system and comprises the following steps: and configuring third network associated data including parameter data, performance data, base station alarm data and neighbor cell configuration data.

And integrating the first network related data, the second network related data and the third network related data to obtain the network related data required by the step S1131.

And S1132, analyzing the abnormal indexes of the problem road sections, matching the abnormal indexes with the network associated data, and inquiring a preset problem table to determine the root cause of the problem.

The problem root cause is a fundamental expression of the network failure problem, and in this embodiment, the common problem root causes include:

base station/cell failure: if the service cell of the problem road section or the cell within a certain distance range has a fault, judging that the base station/cell has the fault;

mode three interference: if the PIC of the service cell and the PIC of the adjacent cell of the problem road section are the same in modulus 3 and the RSRP is within a certain range, the service cell and the adjacent cell are judged to be the interference of modulus three;

and (3) neighbor missing: if the neighbor cell corresponding to the service cell of the problem road section is not in the neighbor cell configuration data and the difference value between the RSRPs is within a certain range, judging that the neighbor cell is missed;

uplink interference: if the ratio of uplink RB larger than-100 dBm in the parameter data and the performance data is larger than the threshold value, determining that the uplink interference exists;

cell congestion: if the number of the service cell users of the problem road section in the performance data is larger than a threshold value, the cell is judged to be congested;

scheduling problem: analyzing indexes of log scheduling data such as downlink scheduling quantity, downlink maximum RB number and the like to analyze whether a scheduling problem exists;

2G is removed: analyzing switching data among systems, judging whether a 2G problem occurs or not by switching from a 4G network to a 2G network;

the switching is not timely: analyzing a switching event in the system, judging whether the RSRP of a service cell of a problem road section is continuously deteriorated or not, if so, judging whether the problem of untimely switching exists or not;

RRC reestablishment: the RRC reconstruction inevitably brings necessary time delay to the service, whether the RRC reconstruction occurs or not is analyzed from a log event, and whether the problem is the RRC reconstruction is judged;

NR cell addition failure: in analyzing the no-residence problem of the 5G network, it is necessary to analyze whether a problem of NR cell addition failure occurs.

The relationship between the problem root cause and the network association data can be determined by querying a multi-data source collaborative mobile network problem location association table (i.e., a problem table) as shown in fig. 3.

And S114, performing network optimization based on the problem root and generating an optimization record, and generating a problem road segment library based on the optimization record.

In this embodiment, for the problem root cause occurring in step S113, optimization is performed by combining processing experiences of different problem root causes, and generally, each problem root cause adopts multiple different optimization manners and records optimization results of different optimization manners to determine an optimal optimization manner. When a problem road section library is formed, an optimization record is formed aiming at the problem of network faults (the road section with the problem) in the drive test data, and the optimization record comprises information such as problem description, test time, test round, problem root cause, optimization results and the like.

Optionally, in some embodiments, the network optimization work order includes a customer complaint work order, as shown in fig. 4, the step S120 of extracting the optimization record of the corresponding problem road segment according to the matching of the network optimization work order and the problem road segment library includes S121 to S123:

and S121, extracting fault information in the customer complaint work order.

And S122, matching the problem road section library based on the position in the fault information to determine a corresponding problem road section.

And S123, extracting the frequency, interval, phenomenon, reason, historical optimization scheme and optimization effect of the faults of the corresponding problem road section in the problem library within preset time.

Steps S121 to 123 are processes of quickly knowing a network fault cause according to a customer complaint work order, where the customer complaint work order includes information of a user complaint, where the information generally includes IMSI, mobile phone number, time period, location, problem description, and the like, and fault information can be determined by means of keyword extraction and the like according to the information of the user complaint, but considering that the expression of the user is often not professional enough, accuracy of directly locating the fault cause is low, so that matching of a problem road section can be performed according to the location, thereby quickly retrieving fault information having a history record corresponding to the problem road section, including times, intervals, phenomena, causes, a history optimization scheme, and an optimization effect, thereby quickly responding to the customer complaint work order, and improving user experience, and correspondingly, step S124 (not shown) is further included after step S123: and S124, taking the failure times, intervals, phenomena, reasons, historical optimization schemes and optimization effects of the corresponding problem road sections in preset time as preliminary conclusions to be replied to the client.

Optionally, in some embodiments, the network optimization work order includes an alarm work order, as shown in fig. 5, the step S120 of extracting the optimization record of the corresponding problem road segment according to the matching of the network optimization work order with the problem road segment library further includes steps S125-127:

and S125, extracting abnormal index information in the alarm work order.

And S126, matching the problem road section library based on the influence range of the abnormal index information to determine a corresponding problem road section.

And S127, extracting the failure times, intervals, phenomena, reasons, historical optimization schemes and optimization effects of the corresponding problem road sections in the problem library within preset time.

And S125-127 is a process of knowing the network fault reason according to the alarm work order generated by the system, and the KPI (Key performance indicator) guarantees daily work of network operation and maintenance. Once the network KPI index is degraded, a large amount of manpower is consumed to perform troubleshooting and solution, and more times, the position of the problem is determined by performing drive test and then optimized. In the embodiment, the problem road sections are quickly positioned according to the influence range of the abnormal indexes, so that the network overall appearance related to the abnormal indexes is known, and the faults and the optimization scheme which may occur in the influence range are known, so that network optimization is performed in a targeted manner, and the workload and the processing delay of the drive test are reduced.

More specifically, in some embodiments, step S130, as shown in FIG. 6, includes steps S131-133:

s131, performing fault matching based on the network optimization work order and the optimization records to determine the optimization scheme of the same fault.

And S132, optimizing the network based on the optimization scheme and confirming the optimization effect.

And S133, if the optimization effect meets the preset requirement, ending the work order, and updating the problem road segment library.

The steps S131 to S133 are a process of processing the network optimization work order according to the optimization record, which is a result obtained according to the problem road section matching, so that how to solve the problem of the network fault in the network optimization work order is not specified, and at this time, further positioning is required to find a root cause of the fault in the network optimization work order. Specifically, in this embodiment, the network optimization work order and the optimization records are matched to search for the same fault in the network optimization work order and the optimization records are specified according to the determined same fault, and then the network optimization is performed according to the optimization scheme, but it has been mentioned above that description about the fault problem in the network optimization work order may not be accurate enough, so that the optimization effect needs to be confirmed, when the optimization effect of one optimization scheme does not meet the preset requirement, the optimization scheme needs to be reassigned or the same fault needs to be reproduced and positioned, when it is determined that the optimization effect meets the preset requirement, the work order is considered to have been solved, the work order can be ended, and the problem road section library needs to be updated according to the current processing of the work order in order to enrich the problem road section library.

On the basis of the embodiment, the resume process of the problem road section library, the processing process of the network optimization work order and the process of the network optimization are further limited and supplemented, the problem road section library which takes the problem road section as a core is established by rich multi-source network data, comprehensive management of the problem road section is convenient, different processing modes are provided for different work orders, quick response can be carried out on the customer complaint work order, the use experience of a user is improved, the troubleshooting burden can be reduced for the alarm work order, and the pressure of workers is reduced.
