Design and Implementation of GPRS Software Communication Module

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.
