The method of emergency communication is divided into a case where the mobile station requests an emergency service in a state that the mobile station is registered with the base station and a case where the mobile station requests an emergency service in a state that the mobile is not registered with the base station. In case of the one case, the mobile station requests the base station of an emergency service using a newly defined emergency code or a conventional bandwidth request code and negotiates a basic function required for an emergency service with the base station through predetermined header data. In case of the other case, the mobile station starts initial ranging using a newly defined emergency code or a conventional initial ranging code and negotiates a basic function required for an emergency service through a subscriber basic capability message (SBC-REQ/RSP)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of emergency communication in broadband radio access system","description":"A method of emergency communication between a mobile station and a base station in a broadband radio access system and a mobile station which supports the method of emergency communication are disclos","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8514747","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.
