通用分组无线服务(GPRS)技术GPRS 将信包交换模式引入到 GSM网络中,从而提高了资料利用率。GPRS可提供高达115kb/s 的传输速率,并能支持 Internet 的 IP 协议及 X.25协议。GPRS 的基本原理是使多个用户共享某些固定的信道资源。它将每个时隙的传输速率从9.6kb/s 提高到14.4kb/s。实现 GPRS 网络需要在 GSM 网中引入新的网络接口和通信协议。增加的网络节
General Packet Radio Service (GPRS) technology GPRS introduces the envelope exchange mode into GSM network, thus has improved the data utilization rate. GPRS can provide up to 115kb / s transfer rate, and can support the Internet’s IP protocol and X.25 protocol. The basic principle of GPRS is that multiple users share certain fixed channel resources. It increases the transfer rate per time slot from 9.6kb / s to 14.4kb / s. Achieve GPRS network needs to introduce new network interface and communication protocol in GSM network.
