A disaster recovery method and device of media server

Abstract

The invention discloses a disaster-tolerant method and a disaster-tolerant device of media servers and is characterized in that the method comprises the following steps: step S102, a disaster-tolerant configuration data is set in a media server; step S104, when the exceptions of one from a plurality of media controlling server modules are detected, according to the disaster-tolerant configuration data, one media controlling server module from the media controlling server modules is selected as a new media controlling server module; step S106, other media controlling server modules from the media controlling server modules are re-registered to the new media controlling server module, thus recovering the work of the media server. Therefore, on the base of requiring no additional production investment, the method markedly improves market competitiveness and the reliability of devices and systems, and has obvious economic and social benefits.

Description

technical field [0001] The present invention relates to the field of next-generation network communication, in particular to a method and device for realizing media server disaster recovery in the next-generation network system. Background technique [0002] In the next-generation network up to 3G network, it mainly includes: Softswitch, which is the core call control component in the next-generation network, is used to complete the call control function, and at the same time provide a service trigger mechanism, which can initiate a service request to the application server according to the service trigger policy ;The application server is the core component of the intelligent network, which stores user data and business logic, and triggers the business process according to the business logic. During the business processing process, it controls the media server to provide media resources as needed, thereby realizing various business functions; The server provides unified med...

Problems solved by technology

[0003] In most of the media server architectures currently adopted by China Telecom, centralized deployment is adopted. The core control modules and resource modules are all concentrated on the unified service platform. Such deployment directly brings the risk of single point of failure, although Part of the disaster recovery function can also be realized through dual-machine and other backup technologies, but because of the single physical location, it is fundamentally impossible to solve the single failure risk caused by geographical / environmental disasters

[0004] In addition, for some media servers that implement distributed deployment, in order to enable them to support disaster recovery and backup functions, they must be implemented in the form of 1+1 or n+m Redundant configuration to ensure disaster recovery when a disaster occurs, but this method brings problems of increased equipment and cost investment

At the same time, since there are multiple sets of media servers in the deployment of this mode, the cost of management and maintenance is greatly increased, which is very inconvenient
