GPRS是通用分组无线业务(General Packet Radio Service)的简称，它突破了GSM网只能提供电路交换的思维方式，只通过增加相应的功能实体和对现有的基站系统进行部分改造来实现分组交换，这种改造的投入相对来说并不大，但得到的用户数据速率却相当可观。本实例教授大家GPRS基础知识。-GPRS is General Packet Radio Service (General Packet Radio Service) abbreviation, it broke through the GSM circuit-switched networks can only provide a way of thinking, only by increasing the corresponding functional entities and the existing base station system part of the transformation to achieve packet switching, this transformation is not relatively large, but the user data rate is considerable. Professor of the examples of the basic knowledge we GPRS.
