摘要
Android是一款应用于智能手持终端的开源手机操作系统。作为手机,短消息服务无疑是一项重要功能。详细论述了GSM SMS PDU的协议字段含义,在此基础上,结合短消息编解码原理,给出了Android平台下,RIL层SMS发送解码和SMS接收编码的具体工作流程;实现了text模式下,CDMA EvDo无线通讯模块在Android平台上的短信收发功能。
Android is an open-source operating system which can be used for smart hand-sets such as cell phone. It is no doubt that SMS （i. e. , short message service） is an important functionality of cell phone. The meaning of protocol fields of GSM SMS PDU is discussed in detail in this article. Based on this and the SMS encoding/decoding principle, we propose the workflow of encoding （for receiving） and decoding （for sending） for Android platform in RIL layer. Moreover, we implemented the SMS sending/receiving functionality of CDMA EvDo communication module in text mode.
