PTN在深圳移动TD-SCDMA中的应用

Application of PTN Used in the TD-SCDMA by Shenzhen Branch

分组传送网(PTN)是具备传送功能的分组化网络,主要用于解决无线接入网(RAN)的IP化承载。本文首先分析了目前常见的PBT/T-MPLS分组传送网络技术,然后探讨了PTN组网方式的特点,最后结合深圳移动目前PTN实验网在TD-SCDMA网络建设中的情况,分析了PTN组网在当前及今后网络建设中的模式。

As a pocketsize network with transmission function,Packet Transport Network(PTN) is mainly used for the IP service bearing of Radio Access Networks(RAN).It analysed the common PTN technology like PBT/T-MPLS firstly.Then explore the characteristics of the PTN networking method.At last,according to the current construction of PTN on TD-SCDMA which built by Shenzhen branch,analyzed the construction mode of PTN in the current and future.
