An efficient handover mechanism is needed to facilitate seamless user equipment (UE) handover for public 5G to public 5G handover scenarios and also for public 5G to private 5G handover scenarios. The traditional approach for UE handovers can cause several minutes of delay when handing-over between public to private 5G networks. In order to address such issues, this submission proposes novel techniques that can be embedded within Third Generation Partnership Project (3GPP) call flows that will allow the network to query a UE about the available networks the UE can see in order to guide the UE to the best network to which to connect based on internal policies/logic. Having such an ability is highly desired by private 5G network operators. Accordingly, techniques herein facilitate efficient UE handovers for such public to private 5G handover scenarios.
