基于IP方式的GPRS终端的研究与设计

The Study and Design of The GPRS Terminal Based on IP

在对多种GPRS终端硬件设计方案分析和论证的基础上,选择了内置TCP/IP协议软件包的Rabbit2000作为GPRS终端的MCU(微处理器),同时针对GPRS终端使用的特殊性,并根据自身的特点,选择了由GPRS终端提供商提供目录服务的网络拓扑结构。详细介绍了基于Rabbit2000的GPRS终端硬件设计思路,并根据所选组网方案及该GPRS终端的特点编写其软件系统,论述了软件系统的设计思路及特点,最后给出了主要模块的流程图。

With a review of design approach of GPRS Wireless Data Transmission Terminal, the hardware solution using Rabbit2000 MCU with embedded TCP/IP software kit was determined by the careful analysis of some hardware solutions.the network topology structure with the catalogue service provided by the GPRS Terminal provider also was chosen as the network construct scheme of the GPRS Terminal after comparing with other schemes, GPRS Terminal hardware design method, according to the chosen network structure, GPRS Ter...
