Abstract: A method, a device, and a system for sending and receiving messages are provided. The method for sending messages includes: receiving, by a Mobility Management Entity (MME), an Earthquake and Tsunami Warning System (ETWS) message; setting an information change identifier if the received ETWS message is different from the ETWS message stored by the MME; and sending the received ETWS message and the information change identifier. In the embodiments of the present disclosure, the MME decides whether to send the ETWS message to the eNB. Therefore, the eNB needs only to transmit the received message to the UE transparently, and does not need to judge the content of the ETWS message, thus simplifying the process of the eNB sending the ETWS message and reducing the load of the access network device.

Abstract: The present invention discloses a data transmission method, base station and terminal. The method comprises: transmitting, in every subframe used for transmitting multimedia broadcast multicast service (MBMS), n transport blocks (TBs) to terminals, and transmitting to the terminals the correspondence between the MBMS corresponding to each TB in the subframe and the TB serial number of each TB in the subframe; wherein n is an integer greater than one, a period of time occupies in every subframe by the TBs corresponding to same MBMS is same, and each TB in the subframe corresponds to a unique TB serial number. The present invention can transmit two or more TBs to terminals in every subframe, and the TBs transmitted in the subframe can correspond to different MBMSs, thereby realizing the transmission of TBs corresponding to a plurality of MBMSs in a subframe and improving the spectrum effectiveness of the data transmission.
