Abstract
The present invention relates to a method and apparatus in a Media Gateway (MG) for handling disconnection between the MG and a Media Gateway Controller (MGC). Multilevel requirements are fulfilled by setting different timeout periods for a disconnection timer. On the one hand, if the timeout period of the disconnection timer is not equal to zero, new events that occur during the disconnection are stored. Then, after the connection is recovered, the stored new events are reported to the MGC, so that the data and states in the MG can match those in the MGC after the connection recovery. On the other hand, if the timeout period of the disconnection timer is equal to zero, all active calls are immediately released.
