「顯示子摘要」計數說明

簡介

本文檔描述了使用「show sub summary」命令報告的訂戶計數中的不一致。通常，「show sub summary」中的所有訂戶型別的計數加到頂部的「Total Subscribers」計數。但是，如果訂戶同時存在專用和預設承載，並且使用某些限定符，則可能導致各種訂戶型別的計數與「Total Subscribers」的預期計數不匹配。

透過範例提供說明

計算VoLTE使用者的專用和預設承載數

在長期演化語音(VoLTE)的情況下，IP多媒體系統(IMS)應用點名稱(APN)有一個專用和預設承載，對於所有VoLTE呼叫的設定至關重要。對於每個唯一使用者，即使每個使用者有兩個承載，Show sub summ（顯示子總和）欄位的增量也為1。但是，每個使用者都有兩個承載的事實在CLI的子部分中被捕獲。例如，請注意，pgw-gtp-ipv6計數表示IMS APN的專用和預設承載的計數，而Total計數僅捕獲兩個承載都用於同一IMS APN的事實。這一點進一步由實際列出各個承載的pgw-only限定符確認，但是與非pgw-only版本一樣，通過Total欄位每個APN只計算一個訂戶一次。

這些範例取自包括LTE和增強型高速封包資料(eHRPD)通話型別的封包資料網路閘道(PGW)。

請注意，pgw-gtp-ipv6(LTE)+ pgw-pmip-ipv6(eHRPD) — 專用承載總數=總使用者數

當您僅通過專用承載使用QCI = 1傳送語音資料的VoLTE使用者進行資格認證時，這一點就更加清楚了。在這種情況下，請注意pgw-gtp-ipv6大約是總使用者數的兩倍，因為它會計算每個VOLTE使用者的專用和預設承載。

計算共用相同日曆的專用和預設承載

一個相關的示例是按日曆列出訂閱者。單個小球代表給定APN的所有承載，而共用該小球的所有承載(2)被單獨列出/計數。同時，Total欄位僅增加一次，以便表示APN的所有承載。在本示例中，IMS預設持有人ID = 5,IMS專用持有人ID = 7。

適用於專用/預設承載的限定詞與所有使用者的混合

最後，可能最令人困惑的例子是，在承載層以及整個使用者上連續使用多個限定符。在此範例中，第三個限定符會新增到已連線時間超過一天(86400秒)的狹窄訂閱者中。 由於此示例還使用代表VoLTE使用者的QCI 1，因此可能預期命中清單為空，因為多少人在呼叫中超過24小時？但結果並非預期的真正的AND運算。即，結果不是已連線時間超過一天的IMS VoLTE會話，因為該數量可能為0。相反，結果是所有IMS使用者均具有VoLTE會話，並且預設IMS或專用(VoLTE)IMS會話已開啟時間超過一天(前者並不罕見)。

在此輸出中，connected-time greater-than qualifier確實將輸出限制到在預設IMS承載上已連線超過一天的用戶，而不考慮呼叫連線時間的限定符。

附註：Internet APN預設的連線時間在您輸入該命令後的幾分鐘內，因此可以確定它是預設IMS承載者，其連線標準大於一天（連線時間為8月7日20:01:23），這將導致報告此訂戶。
