摘要
随着 3G 产业的不断向前发展,3GPP 产业联盟研发出的以 3G 技术为基础向前
演进的 LTE 技术成为世界通信产业界的研究热点。TD-LTE 系统作为我国自主研发
的具有完全知识产权的 LTE 通信协议中的一个标准,也越来越受到关注。
产业技术的提升必然带来大量测试系统的需求以及测试平台的重大变革,为此,
本文在研究 LTE 无线网络结构和虚拟仪器技术的基础上,提出了一套基于虚拟仪器
技术的 TD-LTE 终端测试系统设计方案,以 LabVIEW 为编程语言,构建了整个系统
的软件平台及其相应测试模块,实现了对现有测试协议所规定测试用例的支持。该
系统支持 3GPP -1 所规定的 54 个终端测试用例,可实现相应测试数据的分
析、计算、图表显示以及实时更新,提供了丰富的接口以供日后扩展。
本文首先概述了 TD-LTE 产业发展背景和无线终端测试技术;然后重点探讨了
系统软硬件架构以及实现的核心技术,实现了测试系统与用户终端之间的信令交互、
入网查询以及数据的采集与分析等功能,同时就虚拟仪器对硬件的控制进行了深入
研究,并基于此对校准技术和实现进行了详尽的阐释;最后介绍了整个系统的测试
流程,并以一个测试用例为例简单介绍其实现方式,对测试结果进行了分析,验证
了系统能够对用户终端进行一致性测试,基本达到设计要求。

Abstract
With the development of 3G industry, 3GPP industrial alliance excogitated 3G-based
LTE(Long Term Evolution) technology became the hot point of the world's
communications industry. As one of the standard of munication protocols,
independently developed by China which has fully intellectual property, TD-LTE getting
more noticed by others.
The progress of industrial technology brought us a large number of test systems and
major revolution on test platform. For this reason, based on LabVIEW as the program
language, this paper proposed a set of Virtual Instrument-based TD-LTE Users Equipment
Integrated Testing System design scheme, which Constructed the software platform of this
system with correlated test modules, it can supports all the test use case of the current test
protocol. This system supports 54 users equipment test use case which regulate by 3GPP
-1, it can implemented correlating analysis, calculation, graphic display and
real-time updating of the test data. It also provides a rich interface for future expansion.
The TD-LTE industrial development background and wireless users equipment test
technology were presented in the first place. Then focused on the s
