A method for reporting events by a media gateway in a next generation network includes: executing a state machine which is established in a media gateway and includes service states driven by events, the state machine including a state of Suspension; the executing process includes: entering into the state of Suspension when an event is reported, if the state machine is in a state other than the state of Suspension; and storing an event which can not be reported temporarily in an EventBuffer queue which is established in the media gateway, and returning to a state prior to the state of Suspension when the event reported is responded, if the state machine is in the state of Suspension. A media gateway for reporting events in a next generation network is also disclosed.
