FreeDiameter ULA/ULR messages

Question

I try to connect my entity (as MME) with HSS by s6a interface. Connection (CER / CEA) is successful:

there is report and configuration file for test_app in my cloud

however after that I cannot obtain correct ULA: ULA screenshot

I use test_app.fdx. Maybe it is impossible to use this extension for this aim?

If yes, how can I achieve correct results?

Thank you for your time!

Answer 1

Diameter error code 5005 means the mandatory IE is missing. So check the ULR message sent from the tool and match with the 3gpp specs for mandatory AVP that is missing.

Answer 2

ULA Screenshot have Failed AVP {Auth-Session-State} which is mandatory AVP in ULR.

Can you try uncommenting below line in you configuration?

auth-session-state = 0;
