摘 要
上海貝爾 TD-LTE 無線網(wǎng)絡(luò)日常維護(hù)指導(dǎo)書的對(duì)象為 TD-LTE 無線工程師， 他們負(fù)
責(zé) E-UTRAN 的維護(hù)和管理。本文分別從 eNode B 側(cè)和 SAM 側(cè)的兩方面闡述了對(duì) eNode
B 的維護(hù)操作： 一、 eNode B 側(cè)使用本調(diào)軟件 NEM 對(duì)維護(hù)對(duì)象操作； 二、 SAM 側(cè)對(duì) eNode
B 的操作維護(hù)。
本文分為三個(gè)章節(jié)：第一章介紹了 TD-LTE 的基礎(chǔ)概念及關(guān)鍵技術(shù)；第二章講述了
TD-LTE eNode B 維護(hù)基本操作；第三章對(duì) TD-LTE 無線網(wǎng)絡(luò)典型故障一一做了詳細(xì)講
解。
隨著 TD-LTE 技術(shù)發(fā)展及公司產(chǎn)品的演進(jìn)， 文檔同步更新。
關(guān)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
