| 摘 要： | 本文从无线网络特点的角度出发,从网络使用者最熟悉的GSM对传输网络的需求分析着手,分析了无线网络的基本特征对传输网络的需求。通过对比3G包括IP化在内的不同于GSM的新需要,提出在3G的回传网络上,哪些功能与性能是必须借鉴2G传送网的,哪些是必须在2G回传网络上提升的。基于以上分析,对于业界呼声很高的PTN产品,给出有利于现网平滑演进的PTN网络所必须具备的功能模型。

| Abstract: | Based on wireless architecture and GSM transmission requirement which have been confirmed by operators,this paper describes the basic qualification of normal wireless.Comparing with 3G new features in including IPed total architecture,the authors detects which point might be given up and which should be persevered even promoted in the new UTRAN backhauling network.As per PTN which have been accepted popularly,the result shows the PTN feature model and bottom line which should be aware of and required in incumbent network migrated from TDM oriented 2G to Packet based 3G. |
