In the conference backup method provided by this embodiment, a first management node detects a state of a first conference service module that provides a conference control service and a conference media forwarding management operation for a current teleconference, and sends first state information to a second conference service module after detecting that the first conference service module is in an abnormal state, where the first state information includes a conference state and conference information recorded by the first conference service module, so that operations executed by the first conference service module in the abnormal state can be migrated to the second conference service module; the conference backup method provided by the embodiment solves the problem that in the conference backup process in the prior art, when the master MCU fails, the standby MCU is required to restart the conference, so that the conference is interrupted, the intelligence of the conference backup method is improved in response, and meanwhile, the working efficiency of the teleconference is improved.
Further, in the method provided by this embodiment, the function of the MCU is implemented by the working node where the first conference service module and the second conference service module are located, instead of implementing the function of the MCU by specific hardware in the prior art, which can reduce the cost of deploying and operating a large-scale conference system, so that a user of each participant terminal can use the conference system to participate in a teleconference like using an Email (Email), a telephone, and a computer.
It should be noted that, in the embodiment of the present invention, the conference system may include N conference service modules, each of which may be in a different working state, for example, some of the conference service modules are providing services for other remote conferences, and the method provided in this embodiment may further include, after the first management node detects that the first conference service module is in the abnormal state, before sending the first state information to the second conference service module: the first management node selects one conference service module in an idle state from N conference service modules as the second conference service module, wherein N is an integer greater than or equal to 2; the second conference service module in this embodiment may be selected from a plurality of conference service modules in the conference system, and specifically serves as a standby conference service module of the first conference service module to participate in subsequent service work of the current teleconference.
In a specific implementation of this embodiment, when selecting the second conference service module, the first management node may preferentially select a conference service module that is not in the same working node as the first conference service module, for example, so as to avoid failure of the conference backup method in the execution process due to a hardware failure, thereby ensuring that the current teleconference is performed smoothly.
As shown in fig. 4, a schematic structural diagram of another conference system for executing the conference backup method provided in fig. 2 is shown, and on the basis of the above embodiments, the conference system further includes a conference media service module 13, a call service module 14, and a call media service module 15; the method shown in fig. 2 further includes, after S120: s130, the first management node sends indication information to the second conference service module, where the indication information is used to indicate that the second conference service module sends notification messages to the conference media service module, the call service module, and the call media service module, the notification messages are used to notify that the second conference service module executes a conference control operation and a forwarding management operation of conference media in the current teleconference, and the notification messages may include a Uniform Resource Locator (URL) of the second conference service module. It should be noted that the conference system in the embodiment of the present invention is not limited to the several service modules, and may further include other service modules, and the embodiment takes an interaction manner between the second conference service module and the several service modules as an example for description.

Similarly, the conference service module 13, the call service module 14 and the call media service module 15 may also run on distributed working nodes, all the service modules in this embodiment may share one working node, or some of the service modules may share one working node, for example, the second conference service module 12 and the conference media service module 13 may run on one working node, or each service module may run on a different working node, as shown in fig. 4 by way of example where each service module runs on a different working node, the first management node 10 is responsible for managing conference resources on each working node, i.e., services provided by each service module, if the first and second conference service modules run on one working node, when the first conference service module fails, the operations performed by the first conference service module may be migrated to the second conference service module, however, when the working node is in fault, the second conference service module cannot implement the backup service, and therefore, the deployment manner of each service module in the conference system shown in fig. 4 is favorable for implementing the function of the MCU, because each service module runs on a different working node, a certain service module does not affect the progress of the whole conference when the service module is down and recovered, and if the working node where the first conference service module is located is powered off, the backup of the current teleconference can be implemented, which is favorable for improving the practicability of the conference backup method.
In this embodiment, when the second conference service module starts to execute each operation of the conference service, the second conference service module notifies other service modules currently used in the conference through a signaling, and in the whole switching process, the other service modules are not changed, and the code stream between the participating terminal and the MCU is not interrupted. Therefore, the method provided by the embodiment can realize seamless switching of the current teleconference under the condition that the first conference service module is down, and the participating terminals are not influenced completely in the whole process.
It should be noted that, in this embodiment, the function of the MCU is implemented by each working node connected to the first management node, and when the capability of the existing working node is limited, the function of the MCU can be extended by increasing the working node.
