摘　　要：移动通信网络中,EPC核心网服务器作为运行通信关键业务的设备,是保障系统安全且有效运作的基础,服务器的任何故障都有可能导致通信关键业务的瘫痪或中断。为了提高通信系统的稳定性,提出了两台服务器共同执行同一任务的双机热备架构模式,首先分析了Open SAF方案的优点,随后介绍了SCTP备份的具体实现方案,最后实验结果证明了基于SCTP协议的双机热备系统可以有效地防止服务器错误的发生,从而保证核心网长期、可靠的服务。In mobile communication networks, as the device for running critical communication services, EPC sever is the basis to guarantee the safe and effective operation of the system. Any failure of the server would lead to paralysis or disruption of critical communications services. In order to improve the stability of communication system, a hot-standby mode that two servers jointly execute the same task was put forward. Firstly, the advantages of the OpenSAF scheme were analyzed. Then, the concrete implementation solution to SCTP backup was introduced. Finally, experimental results demonstrate the dual hot standby system based on SCTP protocol can effectively prevent the occurrence of server errors and guarantee the long-term and reliable service to the core network.
