The network equipment (16A) is configured to detect one or more conditions under which non-access stratum (NAS) keys (26A) that protect NAS communication between the network equipment (16A) and a wireless device (12) are to be refreshed. Responsive to detecting the one or more conditions, the network equipment (16A) is configured to derive, from a base key (24A) on which the NAS keys (26A) were derived, a new base key (24B) on which fresh NAS keys (26B) are to be derived. The network equipment (16A) is also configured to activate the new base key (24B)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protection of non-access stratum communication in a wireless communication network","description":"Network equipment (16A) is configured for use in a wireless communication network.
