基于Diameter的下一代信令网研究

摘要

介绍了核心网演进的SAE解决方案；阐述了SAE系统下的Diameter信令及DRA引入；通过对DRA的分析得出了DRA组网原则及设置原则；探讨了现网信令网向下一代信令网演进的思路。%It describes the solution of core network evolution- SAE, elaborates the introduction of Diameter signaling and DRA in SAE system. It concludes DRA networking principle and setting principle based on the analysis of DRA, discusses the consider-ation of current signaling network evolving to the next generation.
