The process also includes communicating a Session Management (SM) Request comprising the PDU Session Establishment Request to an SMF. The process also includes receiving from the SMF a message that includes: i) the PDU Session ID identifying the PDU session, ii) a PDU Session Establishment Accept message, and iii) a user plane (UP) security policy for the PDU session, wherein the UP security policy for the PDU session indicates: i) whether UP confidentiality protection shall be activated or not for all data radio bearers (DRBs) belonging to the PDU session, and/or ii) whether UP integrity protection shall be activated or not for all data radio bearers (DRBs) belonging to the PDU session."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Security solution for switching on and off security for up data between UE and RAN in 5G","description":"A network node configured to perform a process that includes receiving a PDU Session Establishment Request message for establishing a PDU session, wherein the PDU Session Establishment Request message","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11985496","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.
