18、銜接勝利那么會聽到網絡提示音根據(jù)以上,可以在測試MO時,我們無需聽回鈴音來判別主叫方能否與網絡銜接,只需看到計時開場就算勝利MO一次.Alerting/connect切換根本引見1) 基站和手機都有權益發(fā)起切換。2) FER是怎樣得到的：檢驗1.2s內即240幀的誤幀數(shù)，它經過檢測UW識別字中的16bit或32bit的數(shù)據(jù)能否正確，還有檢驗CRC能否正確，在通訊信道里CRC是CI (邏輯信道標識) SA + I共180 bit數(shù)據(jù)產生的16bit的數(shù)據(jù)，在控制信道里它是由PR(前導碼)CAC(公共接入信道)共170bit數(shù)據(jù)產生的16個bit的數(shù)據(jù)，其中PR在控制時隙中為了更好的實現(xiàn)位時鐘同步

19、，它的數(shù)據(jù)是固定不便的62bit的數(shù)據(jù), 通訊信道里的PR為6bit。PS：在待機是FER值永遠不會高于1。3) 手機側如何判別做什么切換：在此以手機側發(fā)起切換為例子，當RSSI值動搖不大，但FER很大時，闡明收到干擾，但此時離原來的CS的間隔沒什么變化，只是這個TCH信道不能用，那么普通執(zhí)行TCH切換；當RSSI值下降，此時普通來說FER也會升高，那么是闡明原CS不能運用需求執(zhí)行RECALL切換。無縫切換比較特殊，在每個支持無縫切換的手機中會有一系列的參數(shù)來確定無縫切換的門限，總的說是還是看RSSI和FER來確定判別：RSSI： 強信號區(qū)- RSSI-1 當RSSI在某一瞬間跨區(qū)跳變那么做無

20、縫 次強區(qū)- RSSI-2 切換，3個門限按照不同的手機確定， 次弱區(qū)- RSSI-3 228的RSSI-1為40，RSSI-2為36FER:當在1.2秒內FER忽然高于一個特定值時，手機做無縫切換。43種切換在流程上的區(qū)別：recalling切換在流程上和主叫流程相仿，只是少了Alerting和鑒權倆個步驟，而TCH切換由于不需求重新選擇基站那么不需求進展建鏈。無縫切換與 recalling 的區(qū)別：2 ports status,在新的鏈路上CC setup之后斷開原語音通道，所以無縫切換根本對用戶通話不產生影響。根本引見5)切換的典型log語句:在分析R200協(xié)議前,簡單引見一下Sanyo
