How will UE register SA Core and 4G EPC independently?

Hi All.

If 4G operator launches 5G SA, will UE register SA Core and 4G EPC independently based on coverage?

Does SA UE works both networks?

Logically it should work.

There is a concept of single and dual registration. Inter-networking between 2 different Core will take place as well.

Others can comment better here…

Yes, based on idle mode and multi carrier handover strategies based on coverage or quality.
