SA test with OAI-CN

[orion-belt]

Issue Description

I am trying end to end SA test using zmq virtual radio mode. I see that, the UEContextRelease is triggered bit early before setup of PDU session. I have set all parameters as per tutorial.

Setup Details

I am running srsRAN in the docker container.

Expected Behavior

PDU Session Establishment successful. IP: 12.1.1.2

Actual Behaviour

UEContextRelease before PDU session setup. Please check attached pcap. srsRAN_oai_pdu_sess_fail_pcap.zip

Hey,

I see that, the UEContextRelease is triggered bit early before setup of PDU session.

Well, then the core isn't accepting the UE it seems. Check the logs there and if you still think it's and srsRAN issue, also provide the relevant logs for srsENB.

Thanks
