摘要

文章描述了LTE（长期演进）系统的网络结构

在此基础上

设计出了PDN（分组数据网）连接建立过程中专有承载的建立。用SDL（规范描述语言）和TTCN（数表结合表示法）对专有承载建立的实现进行了测试仿真

生成专有承载建立成功的MSC（消息顺序图）

并将仿真结果与协议规范进行比较以验证符合程度。该测试过程已应用于LTE无线综合测试仪表的开发中。

Abstract

This paper describes the network architecture of LTE systems.On this basis

it designs the setup of the dedicated bearer in the process of the Packet Data Network（PDN） connection establishment and tests and simulates the implementation of the established dedicated bearer with the Standard Description Language（SDL） and Tree and Tabular Combined Notation（TTCN）

generating its Message Sequence Chart（MSC）.Then

it compares the simulation results with the protocol specifications for conformance verifitcation.This test procedure has been applied to the development of LTE wireless integrated test instruments.
