文档介绍：摘要
移动通信在过去二十多年中获得了飞速发展,成为现代通信中一个极为重要的领域。九十年代才引入我国的第二代通信系统GSM虽然提供了更高质量的数字话音业务,但是提供的数据业务依然需要提高。的高速发展以及随之而来的网络信息时代要求移动通信系统能提供高速率的数据业务。所以就产生了分组数据交换的数据承载和传输方式。GPRS是General Packet Radio Service(宽频移动数据,又名封包无线数据服务)的缩写,在GSM基础上发展起来的一种分组交换的数据承载和传输方式。作为一项由GSM到3G过渡的技术,在3G并未取代2G的今天,GPRS仍占据着移动通信市场相当的份额。相互融合成一个移动互联网。本文在对移动数据通信发展过程以及需求分析的基础上,就GPRS移动通信网络技术进行了研究,介绍了GPRS的技术优势、体系结构、工作原理以及业务解决方案。仿真系统:为了建立一个有效的仿真系统,一般都要经历建立模型、仿真实验、数据处理、分析验证等步骤。为了构成一个实用的较大规模的仿真系统,除仿真机外,还需配有控制和显示设备。

Abstract
munications in the past 20 years has experienced rapid development, it has e a munications a very important fields. The y s in China was introduced into the second generation of munication system GSM while providing a better quality of digital voice business, but to provide the data business still needs to improve. The rapid development of and the work information age requirement of munication system can provide the high rate of data services. So has the packet data exchange of data transmission and is General Packet Radio Service (broadband mobile data, also known as packet radio data service) stands, in the GSM developed on the basis of data of a packet-switched bearer and transmission. As a transition from the GSM to 3G technology, 3G does not replace today's 2G, GPRS is still occupy a considerable share of the munications market. access services provided by GPRS makes munications and the mutual integrate into a mobile . In this paper, the development of mobile munications, and demand analysis, based on the GPRS work technology to carry out the research, describes the advantages of GPRS technology, architecture, operating principles and business solutions. The simulation system: to establish an effective simulation system, generally have to undergo build model and simulation experiment, data processing, analysis and testing methods. In order to form a practical large-scale simulation system, in addition to the simulator, still need to b
