APPLICATION PERFORMANCE EVALUATION METHOD, EVALUATION DEVICE AND MOBILE COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To perform performance degradation detection and factor analysis of an application in a base station, and display a result thereof.;SOLUTION: A packet between a base station and a gateway is monitored, and an application flow is selected from the packet in accordance with application selection criteria determined in advance. Calculated is an application flow selection and performance-evaluation function which determines whether performance degradation corresponding to each application flow per unit time has occurred, and a performance degradation ratio which the application flow where the performance degradation has occurred occupies, for every type of each application, and calculated is a use ratio of each application per unit time in a base station from each application flow number and data amount, and it is determined from the calculated use ratio and performance degradation ratio in each application whether the performance degradation has extended to the whole base station in accordance with a use ratio and performance degradation reference corresponding to an application type determined in advance.;COPYRIGHT: (C)2012,JPO&INPIT
