是GSM系統(tǒng)提供給用戶的一種數(shù)字業(yè)務(wù),它與話音傳輸及傳真一樣同為GSM數(shù)字蜂窩移動通信網(wǎng)絡(luò)提供的主要電信業(yè)務(wù),SMS的收發(fā)占用的是GSM網(wǎng)絡(luò)的信令信道,不會占用普通話音信道,而且它是雙向通信,具有一定的交互能力。而且SMS具有較高的可靠性,短消息發(fā)送端的用戶可知道短消息是否已經(jīng)到達接收端,由于短消息依靠了SMSC短消息服務(wù)中心的存儲和轉(zhuǎn)發(fā)機制,當(dāng)接收端用戶關(guān)機或不在服務(wù)區(qū)內(nèi)時,SMSC會暫時保存該短消息,接收端用戶如果在規(guī)定時間(通常為24小時)內(nèi)重新處于工作狀態(tài),SMSC會立刻發(fā)送短消息給接收端用戶,當(dāng)發(fā)送成功時會返回發(fā)送端用戶一個確認信號。SMS充分利用了GSM網(wǎng)絡(luò)覆蓋廣的特點和全程全網(wǎng)的優(yōu)勢,具有極佳的移動性,使得任何一個申請了短消息服務(wù)的GSM無線終端用戶在全網(wǎng)范圍內(nèi)獲得服務(wù)。每個短消息的信息量限制為140個八位組(7比特編碼)140個英文字符或70個中文字符。如果超過此長度,則要分多次發(fā)送。
