摘 要
上海贝尔 TD-LTE 无线网络日常维护指导书的对象为 TD-LTE 无线工程师， 他们负
责 E-UTRAN 的维护和管理。本文分别从 eNode B 侧和 SAM 侧的两方面阐述了对 eNode
B 的维护操作： 一、 eNode B 侧使用本调软件 NEM 对维护对象操作； 二、 SAM 侧对 eNode
B 的操作维护。
本文分为三个章节：第一章介绍了 TD-LTE 的基础概念及关键技术；第二章讲述了
TD-LTE eNode B 维护基本操作；第三章对 TD-LTE 无线网络典型故障一一做了详细讲
解。
随着 TD-LTE 技术发展及公司产品的演进， 文档同步更新。
关键词： TD-LTE； eNode B； NEM； SAM

Abstract
ASB TD-LTE Wireless Network Maintenance guidelines for the TD-LTE wireless
engineers. They are responsible for the E-UTRAN maintenance and management on site.
This paper respectively from two aspects, eNode B side and SAM side of eNode B
maintenance operations: The eNode B side use NEM operation and maintenance; Another
SAM side operation and maintenance.
This paper is divided into three chapters: the first chapter introduces the basic theory and
key technology of TD-LTE; The second chapter describes the TD-LTE eNode B maintains
the basic operation; The third chapter of the TD-LTE wireless network typical fault details
one by one.
With the TD-LTE technology development and evolution of the company's products,
documentation updated simultaneously.
Key Words： TD-LTE； eNode B； NEM； SAM
