The method includes detecting a radio link failure (RLF) between the UE and the source e-NB by the UE, and maintaining an active communication service at a service layer of the UE after detecting the RLF and as the UE performs the handoff from the source e-NB to the target e-NB such that the communication service remains continuously active during the handoff, the communication service supporting a first communication between the UE and a third party."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio resource connection (RRC) establishment for wireless systems","description":"Methods and systems for re-establishing radio contact include, for example, a method for performing a wireless handoff for user equipment (UE) as the UE performs a handoff from a source extended Node-","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9642054","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.
