MCU abnormity processing method and system for video conference

The invention discloses an MCU abnormity processing method for a video conference. Through the detection of MCU heartbeat abnormity, the method modifies the state of an MCU, and enables the MCU not to participate in OPR. Meanwhile, whether the abnormal MCU carries other conferences or not is further determined. If the abnormal MCU carries other conferences, whether the abnormal MCU is a slave MCU or a main MCU needs to be judged, thereby carrying out the selection of a new main MCU according to the carrying condition. Meanwhile, the invention also discloses an MCU abnormity processing system for the video conference. The method and system can guarantee that the video conference is carried out stably and normally, improve the safety and reliability of a video conference system, enable a fault processing mechanism to be more flexible, and save resources.
