My RM520N module can not establish the PDU aession successfully.
I checked the core network log and F1AP logs and found the root cause.
The Follow-On Request bit in 5GS registration type is 0, AMF sends UE Context Release command to RAN to release N1 NAS signaling connection.
My question is:
- How can I set the UE’s Follow-on request indicator to 1 in the REGISTRATION REQUEST message?
- How to enable IMS service?
