Issue Description

2023-03-02T10:01:33.390175 [CU-CP ] [W] Could not find valid 5QI 5. QoS map size 2
2023-03-02T10:01:33.390176 [CU-CP ] [E] ue=2: "PDU Session Creation Routine" QoS flow 5QI is not configured. id 1 5QI 5
2023-03-02T10:01:33.390177 [CU-CP ] [E] ue=2: "PDU Session Creation Routine" failed.

Setup Details

I connected Fibocom FM150 with srsran + open5gs.

The problem occurs when creating pdusession for dnn="IMS"

The default 5QI config has only 7 and 9 populated. We should be able to provide an extended config as well. I'll follow up on this. Could you still send full logs please and also PCAPs for this attach? Thanks

[andrepuschmann]

Hey,
attached please find a example config with FiveQI 5, 7 and 9 configured. Give it a try and let us know how it goes. Can you share PCAPs and logs with us?

Noted, we are working on this.

Hey, can you retry with the current version. It should be fixed. I am closing the issue. Please feel free to reopen if needed.

Note, that the configs are now slightly different as now there is a need to specify PDCP configs too.
See the following as an example:
