COMMUNICATION MONITORING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a communication monitoring system that reduces a workload on an operator operating a communication monitoring system and a monitor.SOLUTION: A communication monitoring system comprises: a first base station device 100 (macro-base station) having a first service area; a second base station device 101 (pico-base station) having a second service area which is included in the first service area and smaller in coverage than the first service area; a monitoring device 200 (O & M system); and a terminal device 300 (MS). The first base station device 100 transmits first observation data acquired when it has performed radio communication with the terminal device 300 to the monitoring device 200. The second base station device 101 transmits second observation data acquired when it has performed radio communication with the terminal device 300 to the monitoring device 200. A service quality situation analyzing unit in the monitoring device 200 estimates a cause for why the first and second observation data have been obtained on the basis of the first and second observation data.SELECTED DRAWING: Figure 2
