实现无线互联网接入是移动的无线电网络运营商即将面临的挑战之一。通用分组无线业务是GSM的分组交换扩展，与GSM提供的现有电路交换业务相比，它的开发是为了便于接入基于IP的业务。除了概述GPRS的基本概念、网络结构和协议外，本文还讨论了最终用户使用这种接入技术从Web上检索信息时所感受到的性能。结果表明，GPRS为Web访问等突发应用提供了带宽有效的支持。
Enabling wireless Internet access is one of the upcoming challenges for mobile radio network operators. The General Packet Radio Service is the packet-switched extension of GSM and was developed to facilitate access to IP-based services compared to existing circuit-switched services provided by GSM. Besides an overview on the basic concept, network architecture, and protocols of GPRS, this article discusses the performance the end user perceives when retrieving information from the Web using this access technology.This discussion is based on results obtained from a protocol simulator comprising not only the radio interface protocols, but also the relevant Internet protocols as well as a characteristic application model. The results show that GPRS provides bandwidth-efficient support for bursty applications like Web access.
