摘　　要：介绍了GSM短消息的收发过程和传输时延。对GSM Modem与计算机串口相连,接入GSM网的短消息收发堵塞进行了分析。提出用模函数分配增加的端口数解决GSM Modem的短消息收发堵塞的方法和算法程序。分析表明,增加端口数能提高短消息的收发速度,要根据应用的不同要求和性价比,来选择合适的端口数。给出人工增雨的应用实例,短消息发送和接收框图。实际应用表明,该方法具有很好的性价比,能满足固定或低速车载移动终端传输GPS定位数据和其他短消息文件的要求。　The process of transmit-receive and transmission delay for GSM short message are introduced.A analysis is put forward after switching on GSM network short message transmit-receive stop and connecting with computer serial port.The method procedure to solving GSM modem short message transmit-receive stop with modular function allocating incremen-tal port number is presented.Analysis shows that increase port number can advance the short message transmit-receive velocity and select fit port number according to efficiency charge ratio.In view of application example of short message transmit-receive flow diagram,it shows that the method is good efficiency charge ratioa,nd it can meet the requirements of fix or low speed vehicle mobile terminal transmission and GPS positioning data and other short message documentary.
