In particular, the present disclosure teaches methods, systems and apparatuses for selecting and connecting the UE to a gateway (e.g., an evolved packet data gateway (ePDG)) and a network apparatus (e.g., a packet data network gateway (PGW)). By sending the IP address of the gateway and the network apparatus to the UE before the UE disconnects from the first network (e.g., via a Protocol Configuration Option (PCO) message), the UE is able to connect to the gateway and network apparatus directly without consulting a DNS server or a Home Subscriber Server. These techniques can be useful when no DNS server is available and in virtualized, cloud-based networks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Node selection in network transitions","description":"The present disclosure relates to methods, systems and apparatuses for transferring a user equipment (UE) connected to a first network (e.g., a LTE network) to a second network (e.g., a Wireless Local","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9794771","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.
