Abstract
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. 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.
