Problems solved by technology
When an endpoint in the system fails to work due to geological disasters, network interruption, or equipment failure, etc., it will affect the normal operation of the video conferencing system
If the endpoint is a video conferencing terminal, the above-mentioned impacts are relatively small, and at most users at the location of the faulty endpoint cannot participate in the video conference; but if the endpoint is an MCU, the above-mentioned impacts are relatively large, and the All managed video conferences cannot be held normally. In order to restore these video conferences, it is necessary to urgently coordinate new MCU resources in the network, which involves a large number of configuration modifications
During this process, the time-consuming of enabling and configuring the new MCU will be unbearable for large and important meetings

Embodiment Construction
[0060] As described in the background, in a traditional conference hot backup system including active and standby MCUs, the standby MCU is designated by the system at one time when the conference is initialized. In this case, especially when only one standby MCU is specified in the conference hot standby system, if the standby MCU fails, or the information communication path between the standby MCU and the main MCU fails, causing the main When information synchronization or information exchange cannot be performed between the standby MCUs, the active MCU is in an unprotected state; even if multiple standby MCUs are specified in the system, if one or more of the standby MCUs fails, the original MCU will be reduced. The reliability of some conference hot standby systems that contain multiple standby MCUs.
[0061] The technical solution proposed by the invention is an improved conference hot standby model. When the main MCU or conference management equipment finds that the back...

The invention discloses a method for guaranteeing master MCU to possess standby MCU, and video frequency conference system. The method comprises: when standby MCU is in fault, the master MCU or conference management apparatus sends request message to other MCU; inquiring if other MCU can serve as standby MCU; If answer is yes, then selecting other corresponding MCU as new standby MCU according topreset selection strategy. In the invention, when standby MCU is in fault, the master MCU or conference management equipment can automatically look for a suitable MCU as standby MCU to ensure the master MCU in protected state.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for ensuring that a main MCU has a backup MCU and a video conferencing system. Background technique [0002] A Multipoint Control Unit (MCU) is a device used to implement video conferencing (VideoConference) services, also known as a video conferencing server, and its main function is to coordinate and control video transmission between multiple terminals. The MCU is mainly divided into two parts, namely MC (MultipointController, multipoint controller) and MP (Multipoint Processor, multipoint processor). MC is mainly responsible for coordinating the order of use of transmission channels between terminals and using H.245 to define the specifications of transmission content; MP is actually engaged in audio and video reproduction (mixing), transfer (Switch) and Some video stream processing. In the MCU, the MC is a must-have management function, and the MP is select...
