PROBLEM TO BE SOLVED: To provide a fault detection device, a method and a system to be used for a radio network.SOLUTION: The device includes: a detection unit which compares a plurality of performance evaluation indexes in a fixed period in a radio network with a fault database stored in advance, and based on the comparison result, fixes a fault type in the radio network in the fixed period; and a storage unit which stores the fault data base in advance. The fault database includes a plurality of fault parameter characteristic sets, and each fault parameter characteristic set corresponds to one fault type. Each fault parameter characteristic set includes the statistical characteristic of the plurality of performance evaluation indexes corresponding to the plurality of performance evaluation indexes. The statistical characteristic of each performance evaluation index includes the average and the standard deviation of the performance evaluation indexes.SELECTED DRAWING: Figure 2 |
