Problems solved by technology

[0017] In the first category of positioning methods based on fixed thresholds, the fixed thresholds used are obtained based on the historical experience of maintenance personnel, which are artificially set fixed values, and their rationality lacks scientific demonstration.
The second type of positioning method based on dynamic threshold is to obtain a certain quantile value of all data. Although dynamic adjustment is realized, the judgment conclusion lacks a reasonable theoretical basis and the positioning accuracy is poor.
[0018] In the existing positioning methods for KQI degradation problems, the accuracy of positioning is related to the selection of the threshold. If the threshold is not selected properly, the positioning will be inaccurate.
Moreover, when outputting multiple degraded KPIs, the existing methods cannot distinguish the importance of each KPI and KQI, and can only test the multiple output KPIs one by one to determine the primary and secondary rankings, so the efficiency is low and cannot effectively guide the network optimization

Embodiment 1

[0052] figure 1 A schematic flowchart of a method for locating mobile Internet data service quality degradation provided by Embodiment 1 of the present invention is shown.

[0053] refer to figure 1 According to Embodiment 1 of the present invention, a method for locating mobile Internet data service quality degradation specifically includes the following steps:

[0054] 101. Acquire a KQI sequence within a measurement time period from a KQI monitoring system, the measurement period includes a degradation time point, and the KQI sequence includes a KQI measurement value corresponding to each measurement time point within the measurement period.

[0055] In this step, for the measurement time period where the possible degradation time point corresponding to a KQI degradation problem is located, the KQI sequence is obtained from the KQI monitoring system, and the KQI sequence corresponding to each measurement time point in the measurement time period can be obtained in a target...

Embodiment 2

[0064] For a better understanding of the present invention, the method in this embodiment also includes the second embodiment.

[0065] In Embodiment 2 of the present invention, all the steps of the above-mentioned Embodiment 1 are included, wherein, Step 103 of the method of the above-mentioned Embodiment 1 also includes sub-steps not shown in the following figures, and the Step 103 includes:

[0066] 1031. Use Formula 1 to obtain the first correlation coefficient r i ;

[0067] Formula one:

[0068]

[0069] In the formula, Q is the KQI sequence Q={q 1 ,q 2 ,...,q N},q j Indicates the jth KQI measurement value, P i is the KPI sequence P i ={p i1 ,p i2 ,...,p iN}, i represents the i-th KPI, p ij Indicates the jth measurement value of the i-th KPI, N indicates the length of the sequence, and N is a natural number greater than 2.

[0070] In this step, the correlation analysis formula can be used to analyze the KQI series and each group of KPI series, according t...

Embodiment 3

[0078] For a better understanding of the present invention, the method of this embodiment also includes Embodiment 3.

[0079] In Embodiment 3 of the present invention, all the steps of Embodiment 1 and Embodiment 2 above are included, wherein, after Step 1033 of the method of Embodiment 2 above, Step 104 of the method of Embodiment 2 above also includes steps not shown in the following figure Substeps:

[0080] 1041: Sort the second correlation coefficients in the second correlation coefficient set from large to small.

[0081] It should be noted that the second correlation coefficient is obtained after being adjusted by the first correlation coefficient. Therefore, the closer the second correlation coefficient is to 1, the more relevant KQI degradation is to the KPI corresponding to the second correlation coefficient.

[0082] 1042: Select the KPI corresponding to the Xth second correlation coefficient as the Xth most important cause corresponding to the degradation time po...

Abstract

The present invention provides a method and system for locating mobile Internet data service quality degradation. The method includes: acquiring a KQI sequence within a measurement period from a KQI monitoring system, the measurement period including a degradation time point, and the KQI The series includes the KQI measurement value corresponding to each measurement time point in the measurement time period; M groups of KPI series in the measurement time period are obtained from the KPI monitoring system, and each group of KPI series is a KPI type, and each group The KPI series includes: multiple KPI measurement values ​​in the group of KPI categories; and the length of each group of KPI series is the same as the length of the KQI series, and M is a natural number greater than or equal to 1; for the KQI series and each group Correlation analysis is performed on the KPI sequence to obtain a correlation coefficient set; the correlation coefficient set is analyzed to obtain the KPI corresponding to the degradation time point, and the KPI is determined as an important cause of KQI degradation. The method of the present invention can accurately and effectively determine the KPI corresponding to the cause of KQI degradation.

Description

technical field [0001] The invention relates to a communication technology, in particular to a method and a system for locating mobile Internet data service quality degradation. Background technique [0002] In the era of mobile Internet, the experience perception of user data services is very important, but the KPI (Key Performance Indicator, key performance indicator) used in traditional network operation and maintenance has been difficult to measure the real perception of user services, and it is necessary to rely on KQI (Key Quality Indicator, key Quality indicators) to solve the problem of data service perception quantification and evaluation. [0003] KQI is a user-centered service quality parameter that directly reflects the user's experience, and provides a brand-new performance measurement method for telecommunication products, network products and various services of their constituent products. KQI shields the internal structure of the network and focuses on the s...
