Title: ANALYSIS SERVER AND ANALYSIS PROGRAM
Abstract:
An analysis server analyzes communication in a wireless communication system, and is provided with a processor that executes a program, and a storage device that is accessed by the processor. The wireless communication system comprises a plurality of base station devices each housing a terminal. The analysis server comprises a detection unit that detects a low-quality cell having low communication quality, and a factor specification unit that specifies a low quality factor of the low-quality cell, wherein the factor specification unit specifies that the low quality factor is low received power if received power with which the terminal receives a signal from the base station device is smaller than a predetermined threshold, and specifies that the low quality factor is inter-cell interference if the received power with which the terminal receives the signal from the base station device is larger than the predetermined threshold, and the quality of the signal is lower than a predetermined threshold.
