RM500U: Security Mode failing during Re-Registration procedure

Hi.

Following test has been performed with a RM500U modem:

  1. Make a 5G Registration
  2. Make a 5G De-Registration
  3. Make a 5G Re-Registration; the re-registration is requested using the last 5G-GUTI and accepted by AMF with the previously used SecurityKey. Anyway, the Security Mode Command is failing between UE and gNB.

Here the LOGEL logs and Wireshark trace.

Not able to understand if the issue is at UE or gNB side; not so expert in checking the LOGEL logs.

Can someone help me, please?

Dear @sbertuola
Please share the log as attachment, I can’t download from link.

Hi @silvia. The zipped log is >120MB; do you have a server where I can upload it? I cannot simply add as attachment to the thread.
