摘 要
上海貝爾 TD-LTE 無線網絡日常維護指導書的對象為 TD-LTE 無線工程師， 他們負
責 E-UTRAN 的維護和管理。本文分別從 eNode B 側和 SAM 側的兩方面闡述了對 eNode
B 的維護操作： 一、 eNode B 側使用本調軟件 NEM 對維護對象操作； 二、 SAM 側對 eNode
B 的操作維護。
本文分為三個章節(jié)：第一章介紹了 TD-LTE 的基礎概念及關鍵技術；第二章講述了
TD-LTE eNode B 維護基本操作；第三章對 TD-LTE 無線網絡典型故障一一做了詳細講
解。
隨著 TD-LTE 技術發(fā)展及公司產品的演進， 文檔同步更新。
關鍵詞： 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
