GSM网络SMS业务分析及实现

通过对GSM网络的SMS业务通信机制、短信格式、编码与解码等原理的分析,给出了利用GSM无线模块实现发送短消息的方案,方案说明了利用相关AT命令在PDU模式下进行短消息的发送和控制方法,该方法可用于远距监控、报警等各种实际应用场合。最后,用VC上开发的串口通信程序和支持AT命令的手机验证了该方案。

Analysis and realization of SMS operation in GSM

By the analysi of SMS's communication-mechanism in GSM,short message's format, coding and decode,this paper introduces a scheme which realize to send short message with GSM's wireless module.This scheme show how the short message is sent and controled in PDU model with correlative AT commands,which can be fit for surveillance and alarm in long distance.Finally, serial communication programming is developed to validate this scheme with a handset witch has the function of AT command.
