A Study Of Analysis LTE Mobile Network KPI Data

In maintenance of the LTE 4G mobile system, There are a lot of counter output as system statistical output. Analysis of the results of these data is a very important and arduous work. At some stage, The specialized staff is needed for the important mobile operators. It is time consuming and laborious. Because everybody may make mistake. The results are not always reliable relied on manual analysis. Omission or error is occurred in sometime. Because of the fault is No sign of and sudden in mobile communication system, usually after a manual analysis, It has been delayed for further analysis of positioning opportunity.In order to solve the above two problems, this paper analyze the cell KPI problem of the existence of mobile wireless access system with the software method. The aim is to find the TOPN fault reason of influence cell(e Node B) KPI and the top fault Cells(e Node B) for the reason. This paper will puts two methods and achieves them.1. Fault Choice : Based on certain rules, Selected in line with the rules of Cells(e Node B). Give a preliminary solution at the same time for each reason appeared in the strategy. For implementation of the method, first, read the config file. Then locate the position of counter for the every arithmetic expression of states in the KPI data file. Progressive read KPI index file data and analysis the KPI data according to the rules. According to the results of the analysis, judge whether the output is exist. Write the output data and the relational KPI data line to the output Excel file.2. Top Cells: Compare to history KPI data, Compare the refer KPI with history’s KPI. If the whole day’s KPI is worse. Get the three most important reason for each KPI that influences the results. Get the 10 worst cells for each of the three reasons. Give a preliminary solution at the same time for each of the three reasons. For implementation of the method, first, read the config file. Then read the KPI formula in the KPI data file. Combining the calculation of all KPI file record. Comparison of the combined results, Indicator to judge whether the deterioration. Output deterioration counter and cell.The two software has been used in KPI analysis in the outfield of Guangzhou and Beijing of china mobile. Significantly improves the efficiency of field fault judgment.
