The terminal device has access to a core network via the first network-side device, and has access to the core network via the second network-side device which has access to the core network through the first network-side device. The terminal device calculates an access stratum root key of the second air interface according to the input parameter and an access stratum root key of the first air interface, and generates an access stratum key of the second air interface according to the access stratum root key of the second air interface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for generating access stratum key in communications system","description":"In one example method for generating an access stratum key in a communication system, a terminal device acquires an input parameter, where the terminal device is communicably coupled to a first networ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11483705","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.
