Communication quality analysis system and communication quality analysis method

摘要

Problem to be solved: to determine the communication quality change cause.Communication quality analysis systemAt least one of the facilities to measure communication equipment and communication quality outputLog data acquisition section to retrieve log data including data to be analyzed andCalculate the statistical values of the data to be analyzedA plurality of models for classifying the quality change of communication equipment are made from the calculated statistics.To the classification probability calculated by each created modelA log data analysis section which creates a complex model for classifying the quality change of communication facilities from the values multiplied by the weights of each model is provided.The log data analysis unitThe cause of quality change derived by said composite model isThe operator selects a combination of weights with a high degree of consistency with the cause of the particular quality change.A composite model is produced.Diagram
