The Inter-RAT / EPS Fallback 5G - 4G Mobility Model’s Captures
Method #1: 5G to 4G Inter-RAT Handover
In this method, the N26 interface between AMF and MME uses a Forward Relocation procedure and session management context. Additionally, user plane tunnels in the core network are exchanged over from SMF/UPM to MME/S-GW.
Method #2: 5G to 4G Release with Redirection
In this method, the 5G radio connection is released with the 5G RRC Release instructing the UE to reselect to a 4G cell where a new radio connection can be started for the VoLTE call. In this case, the UE context is transferred from the AMF to the MME over the N26 interface.
The Inter-RAT / EPS Fallback 5G - 4G – Mobility Model captures:
eNodeB: X2
gNodeB: X2 (for 5G NSA configuration)
MME: S1_MME, S11, S6a
S-GW: S11, S5c
P-GW: S5c, S5u, SGi
AMF: N26, N2, S11
SMF: N4, Nsmf, Nudm, Npcf, Nnrf, Namf, Nchf
UPF: N3, N4, N6
