Intro

This Model coverage doc helps to choose which service models to use to run predictions using AGILITY. For a list of all services, protocols, and interfaces that AGILITY supports, see Model Coverage Tables.

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​
