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?
version: RM520NGLAAR01A06M4G_01.200.01.200

Dear @ironman
Could you confirm if APN is correct? And did you configure IP type?

Dear Silvia,
I’m sure my APN: internet and PDU Type: IP match the core network settings.
I wonder if the problem is with “Follow-On Request bit in 5GS registration type is 0”?

Hello @ironman ,
Do you have any updates about the Follow-On Request issue?
Threre are two solutions to resolve this issue:
Enable IMS function of Core Network
Disable IMS setting(APN) in RM520N(I speculate, unsure.)
I choosed option 1, Enable IMS function of Core Network solution.
