Abstract: A network management apparatus in a mobile communication network holds a communication quality index in a normal operation and periodically receives input of a communication quality measurement result from a radio base station control apparatus. When a connection failure count f with respect to a connection request count a of each radio cell is obtained as a measurement result, letting p0 be the call loss rate in the normal operation, an upper probability B of a binomial distribution representing the connection failure count becomes larger than f is obtained (step 524). The negative logarithm of the upper probability B is obtained as the score of the degree of abnormality (step 525). Anomaly of communication is detected when the score of the degree of abnormality exceeds a predetermined threshold value (steps 526 and 527). After that, maintenance control is executed in accordance with the calculated score of the degree of abnormality, thereby appropriately avoiding a fault of the communication system.
