KPI公式備注消息類型數(shù)值消息類型數(shù)值消息類型數(shù)值
試呼次數(shù)以channel request和CM service request同時(shí)出現(xiàn)來確定試呼開始。取channel request次數(shù)、CM service request次數(shù)的小值為試呼次數(shù)channel request次數(shù)9CM service request次數(shù)10試呼次數(shù)9
接通次數(shù)當(dāng)一次試呼開始后出現(xiàn)了Connect，Connect Acknowledge消息中的任何一條就計(jì)數(shù)為一次接通。取Connect次數(shù)，Connect Acknowledge次數(shù)的大值為接通次數(shù)Connect次數(shù)6Connect Acknowledge次數(shù)8接通次數(shù)8
接通率（%）總（Connect或Connect Acknowledge）數(shù)/總（channel request和CM service request）數(shù)×100％接通率＝接通總次數(shù)/試呼總次數(shù)×100％；試呼次數(shù)9接通次數(shù)8接通率（%）88.88888889
掉話次數(shù)在一次通話中如出現(xiàn)Disconnect或Channel Release中任意一條，就計(jì)為一次呼叫正常釋放。只有當(dāng)兩條消息都未出現(xiàn)而由專用模式轉(zhuǎn)為空閑模式時(shí)，才計(jì)為一次掉話。接通次數(shù)-MAX（Disconnect次數(shù),Channel Release次數(shù)）Disconnect次數(shù)5Channel Release次數(shù)6掉話次數(shù)2
掉話率（%）掉話總次數(shù)/接通總次數(shù)×100％接通次數(shù)8掉話次數(shù)2掉話率（%）25
