GSM和GPRS的区别

1.全球移动系统(GSM) ：
GSM 是一种用于移动电话通信的蜂窝标准，用于使用 SMS 对社会产生深远影响的数字调制来满足语音服务和数据传输的需求。它是 2G 技术的标准承载者。 GSM 是一种电路交换网络。在 GSM 计费是基于连接的持续时间。它不允许直接连接到互联网。 SMS(短消息服务)是流行的功能之一。它几乎在所有国家/地区使用，并向大量用户提供服务。

2.通用分组无线业务(GPRS) ：
GPRS 是 GSM 功能在基本功能上的升级，以获得比标准 GSM 更高的数据速度和对分组数据网络的简单无线访问。它是 2.5G 技术的标准承载者。 GPRS 是一种分组交换网络。在 GPRS 中，计费是基于传输的数据量。它允许直接连接到互联网。 MMS(多媒体消息服务)是流行的功能之一。它不能提供给所有国家，因为它仅限于具有适当网络连接的发达地区。
