could you share gnb and srsUE logs? could you share ngap pcap file?

could you share gnb and srsUE logs? could you share ngap pcap file?

I think we had this issue with free5gc, not sure if it was a free5gc issue or something on the gNB/UE end. Will investigate what we went through and post if I have any updates.

Thank you for your response. I have found the issue. The default 5QI in free5gc is 8, but srsRAN_Project does not support it. I set the 5QI in free5gc to 1, and that resolved the problem successfully.
