信令网关集中多模块方案的研究与设计

Research and design of signaling gateway centralized multi-module project

针对线性分布式多模块方案的缺点和问题,在线性分布式多模块设计方案的基础上,提出了一种新的线性集中式多模块信令网关(SG)设计方案;然后根据新的方案,设计了新信令网关中CPCI信令处理系统的板卡配置;最后分析了机框内多模块方案,并针对其中采用单板逻辑结构时出现的问题,提出了关于信令流控制传送协议(SCTP)不同运行环境的两种解决方法。研究结果表明该方案降低了设计方案中偶联建立和配置的复杂性,并且提高了信令网关的性能。

Aiming at shortcoming and problem of the linearity distributed multi-module project, a new linearity centralized multimodule project was proposed based on the linearity distributed multi-module project. According to the new project, a new signaling gateway（SG） board configuration of the CPCI signaling management system was designed. An analysis on frame multi-module project was made, and aiming at the question when adopted the single board logical structure, the two solutions about stream control transmission protocol（SCTP） different operating environment were proposed. The results indicate that the project reduces the complexity on the establish of the coupling and configuration, and it improves the performance of SG.
