摘要
本文首先分析了新时期的挑战,得出发展下一代电信网是历史必然的结论,然后分别探讨了电路交换网和数据网(特别是IP网)的演进思路,最后给出了下一代电信网的特点、结构和演进的思考。
The paper presents some challenges from new era and draw a conclusion that it is logical to make paradigm shifts to next generation telecommunication networks.Then,the paper discusses evolution routes for circuit based switching networks and data networks (focus on IP network),respectively. Finally, some thinking on characteristics, architecture and evolution for next generation telecommunication networks are presented.
