Vendor Huawei

Can you please share the parameters and their MOs in detail that are required to be set on 4G and 5G sides for ENDC mode.

On Ericsson, are there any parameters I need to switch for voice in ENDC?

7

Voice is always handler over LTE in NSA.

But there is the option to disable NSA for VoLTE calls.

Do I need to set a parameter for this?

My issue is when volte is on UEs aren’t camping on 5G but when volte is disabled in setting they are camping on 5G.

I need them to camp on 5G even with VoLTE ON.

9

When you say camp you want to see the 5G icon in idle?

Or do you want to have NSA during VoLTE calls?

What do you see in message flow, does UE gets an attach reject?

10

No.

UE in idle mode and connected mode if VoLTE is on in setting is acting like NSA doesn’t exist.

But when VoLTE is OFF it is connecting to NSA and throughout is NR.

Maybe it helps, in case your 5G NSA is on FR2…

Prerequisites for SN Addition:
FRinhibitEndcFr2Volte = false, Whether EN-DC FR2 is inhibited during VoLTE.
