摘　　要：在GPRS技术受到空前欢迎的背景下,各种硬件GPRS模块层出不穷,但由于GPRS自身的速率瓶颈,限制了其应用。基于此,介绍了一种基于PC机的软GPRS设计方案,该方案通过UART和Ethernet来实现硬件GPRS的功能,支持3GPP TS 27.010 multiplexer协议,能承载基于TCP/IP协议的所有业务,具有成本低廉、稳定性高、对上层协议与应用透明等优点,可应用需要较高数据传输率的工业应用和无线系统开发调试过程中,并可以平滑过渡到基于AP+BP方案的3G应用中。With the unprecedented welcome of GPRS technology by the people,various hardware modules of GPRS spring up.However,the rate bottleneck of GPRS itself restricts its application.Based on this,a GPRS software of GPRS itself module shceme based on personal computer system is proposed.This shceme,through the UART and Ethernet to implement the function of GPRS hardware modules,could support 3GPP TS 27.010 multiplexer protocol,and is able to bear all operations based on TCP / IP protocol.It has the advantages of low cost,high stability,and transparency for the top protocol and applications,thus could be applicable to the industrial applications with higher data rate,and to the development and debugging of wireless systems.And it could realize the smooth transition to 3G applications based on AP ＋ BP.
