摘要
以先进的精简指令(RISC)的ARM9 S3C2410X微处理器为核心,通用无线分组业务(GPRS)和全球移动通讯系统(GSM)模块等组成无线上网系统。通过对网络拨号功能的程序设计,并充分利用Qt/Embedded系统关于网络资源的特点,实现无线MODEM经GPRS连接到Internet的无线网络通信,为了使程序设计更加合理,本文将网络拨号分成两部分,即网络和拨号。经过在嵌入式Linux操作系统上验证测试,本设计既可较好地完成网络拔号功能,又可方便地应用在PDA等智能嵌入式系统中。
Taking the ARM9 S3C2410X microprocessor of an advanced reduced instruction set （RISC） as a core,, usig general packet radio service （GPRS） and global system for mobile communication （GSM） module to construct a wireless Internet access system. Through designing program of the network dial-up function, taking advantage of Qt / Embedded systems on the characteristics of network resources, the wireless network communication of wireless MODEM can be achieved by connecting to the Internet via GPRS. In order to make the program more reasonable, the network dial-up is divided into network and dial-up. After the verification test on embedded Linux operating system, the design can better complete the network dial-up, and can be easily used in smart embedded systems such as PDA and so on.
