摘要
Provided is a communication network quality analysis technique which can identify a network side communication device, a communication area, or a terminal which causes degradation of quality of the communication network detected by an abnormal communication quality index. The technique analyzes a recording content of a call process performed by the network side communication device and acquires a distribution of quality degradation amounts in respective hierarchies such as a terminal, a network communication device, or a communication area. Thus, the technique estimates a terminal, a network side communication device, or a communication area causing degradation of the communication quality according to a degree of quality degradation degree distribution bias considering the belonging relationship of the terminal, the network side communication device, and the communication area.
