问题

服务提供商报告一个MME中4G ASR降级，并且断开原因“mme-hss-user-unknown”增加。

"mme-hss-user-unknown(375)"断开原因描述由于MME HSS用户未知而断开的会话总数。

捕获到的一个故障跟踪报告HSS拒绝身份验证作为AIA消息中的结果代码DIAMETER_MISSING_AVP(5005)。

MME不断从HSS获取“DIAMETER_MISSING_AVP(5005)”，故障AIA消息的样式如下：

故障排除

本部分提供可用于排除ASR KPI因mme-hss-user-unknown断开原因增加而降级问题的信息。

跟踪收集的“监控子”，并将其与成功和失败场景进行比较。从MME到HSS服务器的AIR中缺少支持的功能AVP。

成功的AIR和AIA消息从监控子跟踪中捕获。以下是从MME发送到HSS的AIR消息：

解决方案

似乎“支持的供应商ID”AVP未与DPC卡2协商，因此仅观察该卡的故障。

根据RFC 3588,
Supported-Vendor-Id AVP — 这用于CER和CEA消息中，以通知对等体发送方支持（其子集）由此AVP中确定的供应商定义的供应商特定AVP。
Vendor-Id AVP — 与Supported-Vendor-Id AVP结合使用，以便了解哪些供应商特定属性可能发送到对等体。

为了在直径对等体和客户端之间交换功能，向服务提供商建议此行动计划。

行动计划是迁移DPC卡2和备用DPC卡10。

[local]SGSN-MME-03# card migrate from 2 to 10 
Are you sure? [Yes|No]: yes

服务提供商使用备用DPC卡10执行DPC卡2迁移。

在活动后，支持的供应商ID(10415)对于卡10（具有相应的hss-peer）似乎正常，ASR KPI似乎也正常。

当在MME和HSS之间建立直径对等连接以交换操作直径消息时，支持的供应商ID应为“10415”值。
