The disclosure discloses a method of monitoring Machine-Type Communication device events, wherein a network side detects Machine-Type Communication (MTC) device events; when the occurrence or termination of a MTC device event is detected, sends an event report to a MTC server through PCRF, in which the MTC device event that has occurred or terminated is indicated. The disclosure further discloses, at the same time, a system and network of monitoring MTC device events. With the solution of the disclosure, it can be implemented that the network side reports a MTC device event to the MTC server and processes the MTC device according to the MTC device event that has occurred, as well as recovers normal activities of the MTC device when the termination of the MTC device event that has occurred is detected.
