Responsive to the wireless device returning to the connected RRC state, the RAN node requests new key material from the CN node, and replaces the key material supporting the connection with the new key material received from the CN node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Refreshing a security context for a mobile device","description":"A Radio Access Network (RAN) node instructs a wireless device having a connection to the RAN node to transition from a connected Radio Resource Control (RRC) state to an inactive RRC state in which ke","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11252561","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.
