1、概述GPRS(General Packet Radio Service,通用分组无线业务)是在现有的GSM移动通信系统基础之上发展起来的一种移动分组数据业务。GPRS主要通过在GSM数字移动通信网络中引入分组交换功能实体,从而支持采用分组方式进行的数据传输。GPRS系统可以看作是对原有的GSM电路交换系统进行的业务扩充,以满足用户利用移动终端接入Internet或其它分组数据网络的需求。
1. General Description GPRS (General Packet Radio Service) is a mobile packet data service developed on the basis of the existing GSM mobile communication system. GPRS mainly introduces the packet switching function entity in the GSM digital mobile communication network to support the data transmission by packet mode. GPRS system can be seen as the original GSM circuit switching system for business expansion to meet the user access to the Internet using mobile terminals or other packet data network needs.
