本文描述了使用"show sub summary"命令报告的订阅者计数中似乎不一致的情况。通常,从"show subsummary"中统计的所有订阅者类型的计数加到顶部的"Total Subscribers"计数。但是,订阅者的专用承载和默认承载以及某些限定词的使用可能导致不同订阅者类型的计数与"Total Subscribers"的预期不匹配。
在长期演进语音(VoLTE)中,IP多媒体系统(IMS)应用点名称(APN)具有专用的默认承载,对于设置所有VoLTE呼叫至关重要。对于每个唯一用户,“显示子用户”(Show sub summ)增量为“总用户”(Total Subscribers)字段的1,即使每个用户有两个承载。但是,每个用户有两个承载这一事实在CLI的子部分中捕获。例如,此处请注意,pgw-gtp-ipv6的计数表示IMS APN的专用承载和默认承载的计数,而总计数仅捕获两个承载用于相同IMS APN的事实。这由仅pgw限定符进一步确认,该限定符实际列出了各个承载,但与非仅pgw版本一样,通过Total字段对每个APN的用户仅计数一次。
这些示例取自包数据网络网关(PGW),该网关包括LTE和增强型高速分组数据(eHRPD)呼叫类型。
请注意,pgw-gtp-ipv6(LTE)+ pgw-pmip-ipv6(eHRPD) — 总专用承载=总用户

当您仅通过使用QCI = 1通过专用承载传递语音数据的VoLTE用户进行资格审批时,这一点就更为明确。在本例中,请注意pgw-gtp-ipv6大约是总用户数的两倍,因为它计算每个VOLTE用户的专用承载和默认承载。

相关示例是按被叫列出用户时。单个被叫方代表给定APN的所有承载,而共享该被叫方的所有承载(2)将单独列出/计数。同时,Total字段仅增加一次,以表示APN的所有承载。在本例中,IMS默认承载ID = 5,IMS专用承载ID = 7。

最后,最令人困惑的示例可能是连续使用多个限定符,这些限定符在承载级别以及整个用户中都适用。在本示例中,第三个限定符将添加到连接时间超过一天(86400秒)的狭窄用户。 由于本示例还使用代表VoLTE用户的QCI 1,因此可能预期命中列表为空,因为有多少人在24小时以上的呼叫中?但结果不是预期的真AND运算。即,结果不是连接超过一天的IMS VoLTE会话,因为该数字可能为0。相反,结果是所有具有VoLTE会话的IMS用户,且默认IMS或专用(VoLTE)IMS会话已启动超过一天(前者并不罕见)。
在此输出中,连接时间大于限定符将输出限制为在默认IMS承载上连接超过一天的用户,而没有不考虑呼叫连接时间的限定符。

以下是一个示例,其中给定用户的完整输出符合超过一天的连接时间标准。
注意:输入命令后,Internet APN默认的连接时间在几分钟内,因此您可以确定它是符合连接标准(连接时间为8月7日20:01:23日)的默认IMS承载,这会导致报告此用户。
