摘要
LTE作为后3G时代,承载高速无线数据业务的主要技术已经在全球规模部署,随着LTE牌照在国内发放日趋临近,中国移动将进一步扩大试点规模,并通过新建和升级两种模式,使TD-LTE基站规模超过20万个。同时,中国移动也是全球少数几个采用PTN作为传输手段承载LTE的运营商,LTE规模应用后传送网带来的影响需要引起足够的关注。本文对LTE主要特点进行简要分析,并将其对传送网规划、建设和运维带来的挑战进行了梳理和介绍。
As LTE 3 g era,bearing high-speed wireless data services in the main technology has global scale deployment,as in the domestic issue licences LTE date approaches,China mobile will further enlarge pilot scale,and through the new and upgrading of two modes,TD-LTE base station size more than 200000.At the same time,China mobile is the world a few PTN used as transmission means carrying LTE operator,LTE scale after application of the impact of the transport network need to cause enough attention.In this paper,the paper analyzed the main characteristics of LTE,and its transmission network planning,construction and operation and maintenance,the author discusses the challenge and brief introduction.
