摘　　要：为了实现低时延、无网络中断的用户体验,解决EPC服务器关键业务中断导致通信网络瘫痪的问题,分析了目前3种保障系统高可用性技术的优缺点,设计了一种基于Open SAF开源项目的EPC双机热备系统,通过测试证实了热备份的时延非常小,可以做到EPC关键服务不中断,达到用户无感知的效果,用以确保核心网长期、可靠的服务。In order to achieve the user experience of low delay and uninterrupted network and deal with the communication network paralysis resulted from the interruption of the key service of EPC server, advantages and disadvantages of three techniques to guarantee the high-availability of the system at present were analyzed, an EPC high availability redundant system based on OpenSAF open source project was designed. Experiments show that the high availability system not only has very small delay, but also achieves the uninterrupted EPC key service no impact on user to guarantee the long-term and reliable service of core network.
