VoNR
Voice and data services are transferred via NR. Voice can be smoothly handed over between 4G and 5G edge, and between 4G edge and 3G CS.
EPS Fallback
A 5G UE implements its data service on the 5G network while falls back to the LTE during the voice service establishment. After the voice service is done, the UE moves back to the 5G.
RAT Fallback
A 5G UE implements its data service on the 5G network while falls back to the eLTE (controlled by the 5GC) during the voice service establishment. After the voice session is terminated, the UE moves back to the 5G.
5G SRVCC (R16)
A 5G UE camps on the 5G NR. It can fall back to the 3G network by using 5G SRVCC or handover to the UTRAN CS to establish a voice call.
