当ims-authorization-revoked Disconnect Reason is Pegged时？

简介

本文档介绍show session dis connect-reasons命令如何显示系统中服务过度的内部断开原因。

当ims-authorization-revoked Disconnect Reason is Pegged时？

最常见的场景是PGW接收 从PCRF重新授权请求(RAR)以释放会话。  要了解确切场景，必须收集监控用户（详细程度3和多呼叫跟踪选项）和/或数据包捕获。  以下是监控用户跟踪的一个片段，其中PCRF通过发送RAR和UNSPECIFIED_REASON在Session-Release-Cause释放具有ims-authorization-revoked断开原因的会话。

根据3GPP 29.212:

“如果PCRF由于内部触发或来自SPR的触发而决定终止IP CAN会话，则PCRF应向PCEF发送包含Session-Release-Cause AVP的RAR命令。PCEF应通过向PCRF发送RAA命令来确认该命令。”
