摘要
在对GSM移动通讯系统的短信息(SMS)业务通信中AT指令的介绍,以及短信格式、编码与解码等分析的基础上,介绍了一种使用GSM短信传送任意格式文件的方法,将文件压缩并分割封装成适合短信传送的数据包,通过GSM短信发送给接收方,接收方接收之后将数据包还原、解压得到原始文件,从而实现了通过GSM网络在两台计算机之间传送文件。
On the base of introduction of AT Command in Short Message Service（SMS） of GSM,and analysis of short messages elements,encoding and decoding,this paper introduces a method to transfer file by GSM,Compress the file, then split it and package it to data packages according to the short message＇s specification.Transfer the data packages to the receiver by GSM.After receive all data packages,receiver combine data packages to one,then decompress it to get the original file.This method realize file＇s transfer between two computers by GSM which one or both of them can not access to Internet.
