Handover operations within a 3rd Generation Partnership Project (3GPP) fifth generation (5G) telecommunications environment may be inefficient and unnecessarily consume resources. To address such challenges, techniques are presented herein that optimize handovers through, for example, improving handover latency, avoiding unnecessary N4 interactions, and avoiding additional resource allocations in a User Plane Function (UPF). Additionally, in a home routed roaming case the presented techniques avoid extra resource allocations on a Home UPF (HUPF).
