The method performed by the access node comprises transmitting a broadcast message in a cell served by the access node. The message indicates that the access node supports connectivity to at least one core network associated with another RAN than the standalone LTE RAN. The method also comprises receiving a request to attach from a wireless device in the cell, for establishing a secure connection for user data between the wireless device and a target core network via the access node. The method further comprises transmitting a request to a target core network node to establish the secure connection."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for standalone LTE RAN using unlicensed frequency band","description":"The present invention relates to methods and apparatus for enabling an establishment of a connection between a wireless device and a core network via an access node of a standalone LTE RAN using an un","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9668285","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.
