In response to a report on the radio link problem detection of the first user terminal being sent from the second user terminal to a network apparatus, the first user terminal receives a confirmation on a status of the report from the second user terminal over the device-to-device link. Based on the confirmation, the first user terminal decides, whether to stop a first radio link failure timer, reset the first radio link failure timer, or extend the first radio link failure timer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Handling a radio link failure in communications","description":"A method for a communications system, wherein in response to detecting a radio link problem during a first phase of a radio link failure, the first user terminal transmits an indication of the detecti","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9723647","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.
