The method includes: acquiring, by the network-side device, an input parameter; calculating, by the network-side device, an access stratum root key KeNB* according to the input parameter and an access stratum root key KeNB on the first air interface, or using, by the network-side device, the KeNB as the KeNB*; and generating, by the second network-side device, an access stratum key on the second air interface according to the KeNB*, or sending, by the first network-side device, the KeNB* to the second network-side device."},"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 the communications system, a user equipment UE accesses a core network via a first network-side device by using a first air interface and connects to the first network-side device via a second netw","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9736125","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.
