| 摘要: |
| 下一代网络将是基于软交换系统的通信网络。在研究各种软交换系统互联机制的基础之上,结合软交换基于IP网络构建、信令与媒体分离等特点提出了基于软交换系统的下一代网络中可以采用的各种组网结构,比较了各种方式的优缺点,指明了其适用范围。最后给出了现有通信网向下一代通信网络演进过程中网络体系结构的演进方案。 |

| Abstract: |
| Next Generation Networks (NGN) would be Softswitch-based networks. Based on the analysis of Softswitch interoperation mechanisms, different networking technologies for Softswitch are proposed considering the characteristics of Softswitch, such as IP-based system and the separation between signalling and media.Finally,the migration solution for networking architecture from existing telecommunication networks to Softswitch-based NGN is further presented. |
