Hi Team @wilson30139 ,
While integrating free5gc core with qct RAN, we encountered Authentication Failure errors during UE registration process, resulting in InitialContextSetupFailure (Unsuccessful UE registration). In the attached pcap file, the following errors can be seen;
5GMM Cause: ngKSI already in use
5GMM Cause: Synch Failure
At the AMF side, the error “NAS message is ciphered, but MAC verification failed” can also be seen in the attached AMF log file.
We are stuck at this point and unable to proceed with our project. Any assistance/support from your side would be highly appreicated.
Note: The IP address of AMF is 192.168.123.245 & The IP address of qct RAN is 192.168.123.250. For this integration project, the docker-compose example of free5gc version 3.3.0 is used.
Thanks in advance!
BR,
Maria
