Abstract
An interface conversion device of a mobile communication system includes: a delay amount measurement unit that measures a delay amount from a difference between an input time at which the mobile communication system has acquired a periodically transmitted time-synchronization signal and an output time at which the mobile communication system outputs the time-synchronization signal; a memory that stores delay amount history information including the measured delay amount; a variation evaluation unit that measures a variation amount indicating an instantaneous variation of the delay amount, using the delay amount history information and evaluates whether the variation amount is within an allowable range; and an anomaly detection unit that detects a communication anomaly in the mobile communication system on the basis of a result of the evaluation.
