摘要:

TD-LTE小基站的部署场景、覆盖策略与传统宏基站不同,站址的规划也与宏基站有较大区别,采用传统宏基站PTN回传网络承载TD-LTE小基站将面临三大难题:网络效能低、安全性差、智能性低。对如何建设高效、安全、智能的小基站回传网络进行了研究,结合中国移动网络现状,提出PON+CMNet、PTN+CMNet、PON+PTN、PTN端到端4种小基站回传承载方案,并对这4种方案进行了现网测试验证。验证表明,4种承载方案均满足小基站通信业务需求,采用PON+CMNet承载方案在安全性、智能性、高效性上优于另外3 种承载方案。

Abstract:

The deployment scenario,coverage strategy and site assignment of TD-LTE microcell base station(MiBS) are different from macrocell base station(MaBS). Using PTN backhaul network of traditional MaBS to carry TD-LTE MiBS will face three challenges:low network performance,poor security and low intelligence. How to build an efficient,safe and intelligent backhaul network solution for MiBS was investigated. Based on China Mobile’s current network,PON+CMNet,PTN+CMNet,PON+PTN,PTN end-to-end four kinds of small cell backhaul network solutions were proposed and furtherly tested and verified. The result shows that 4 solutions all satisfy the communication business requirements of MiBS. In particular,PON+CMNet solution is better than the others in terms of network security,intelligence and efficiency.

Key words: TD-LTE microcell base station, efficiency, security, intelligence, PON, CMNe
