The method includes: sending, by an authentication server function AUSF network element, a first authentication vector obtaining request to a first unified data management UDM network element; and if the AUSF network element receives a routing indicator RI sent by the first UDM network element, sending the RI to an access and mobility management function AMF network element. The method is applied to a process in which a terminal updates the RI."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Routing method, apparatus, and system","description":"A routing method, apparatus, and system, related to the field of communications technologies, to update a routing indicator in a subscription concealed identifier when a user is migrated to a new unif","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11974132","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.
