The system for broadcasting and transmitting an ETWS message includes: an ETWS message publishing entity, adapted to publish an ETWS message; a cell broadcast center (CBC), adapted to: encapsulate the ETWS message published by the ETWS message publication entity into a cell broadcast service (CBS) message, and send the CBS message; a mobility management entity (MME), adapted to forward the CBS message sent by the CBC to a radio access network (RAN); and the RAN, adapted to: receive the CBS message forwarded by the MME, and send the received CBS message to a user equipment (UE). The preceding system provides a new technical solution for transmitting an ETWS message, which can guarantee the security of the ETWS message transmission by using the security mechanism of the CBS."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System, apparatus and methods for broadcasting and transmitting ETWS message","description":"The present invention relates to an earthquake and tsunami warning system (ETWS) technology, and in particular to a system, apparatus and methods for broadcasting and transmitting an ETWS message.
