Further including transmitting reception completion responses to the mobile station which transmitted the preamble codes from the base station after discriminating the preamble codes, including transmitting a request for starting broadcast and multicast service to a multimedia-broadcast-and-multicast-service transmission apparatus when the base station first receives at least one of the preamble codes of the specified RACH signals for the broadcast and multicast service, and broadcasting and multicasting, in the base station, of multimedia data supplied by the multimedia-broadcast-and-multicast-service transmission apparatus to the mobile station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Broadcast and multicast service communication method, base station, and mobile station","description":"Controlling broadcast and multicast service communication including transmitting request signaling information for requesting broadcast and multicast service from a mobile station to a base station us","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9775133","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.
