软交换系统纠错技术研究

针对软交换系统软件错误产生的原因及呼叫过程每个步骤可能产生错误的原因进行了分析。基于分析结果提出了分层系统结构优化方案以避免错误的产生,并针对无法避免的错误提出了系统纠错和拥塞纠错概念。根据纠错机制,给出了软交换系统软件架构设计、系统纠错和拥塞纠错等方面解决方法。对纠错机制进行了实际测试,实现了系统错误的处理。

Research on Error Correcting Technology of Softswitch System

This paper analyzes the error reason for softswitch system software and call flow each setp.Based on the analysis results,it proposes the optimization scheme of hierarchical system struction to avoid the error,and the conception of system error correcting and congestion error correcting against the avoidless errors.According to the error correction mechanism,we implement the design of softswitch system software framework and the solution of system error correcting and congestion error correcting.The error correcting mechanism is tested in practice and the system error correcting is realized.
