If you look at the specs 24.301 , it clearly lists down the abnormal cases for each protocol procedure at EMM & ESM.

Here is the verbatim spec wording from R9 24.301 spec , page 57.

If the network receives a DETACH REQUEST message before the ongoing GUTI reallocation procedure has been completed, the network shall abort the GUTI reallocation procedure and shall progress the detach procedure.

Hello,

Pardon me, this is just a theoretical question. Not started my real testing yet. But so meantime trying to see I handle the basic possible scenarios.

In the CCR message of type (Initial Request), lets say PCRF receives both the "QOS" (containing APN AMBR UL and APN AMBR DL) and "Default Bearer QOS" AVP (containing QCI and ARP).
As of now, in my basic code, I return the QOS based on apn info received on "Called-station-ID" AVP. Will it be ok..Or is there any better suggestions on this ?
