The node operates to obtain, from an Access and Mobility Management Function (AMF), a session context request responsive to a handover indication indicating a handover of the session from a Fifth Generation System (5GS) to an Evolved Packet System (EPS). The node identifies whether an uplink classifier (UL-CL) UPF is in use for local offloading to a local UPF anchor for delivery to a local area data network. Based on the identifying, the node obtains uplink tunnel information of the UL-CL UPF instead of the UPF anchor for establishing at least one bearer for the session and sends to the AMF a session context response including the uplink tunnel information of the UL-CL UPF."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Maintaining local offloading of traffic in a handover from a fifth generation system (5GS) to an evolved packet system (EPS)","description":"A network node includes control plane functionality for managing a session of a user equipment (UE) which is anchored at a User Plane Function (UPF) anchor for communicating traffic between the UE and","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11252627","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
