Patent ID: 8543082

Claim:
A method for transmitting a primary notification message of an earthquake and tsunami warning system comprising: after paging a terminal through a paging message containing indication information of an earthquake and tsunami warning system (ETWS) message, a base station scheduling the primary notification message of the ETWS as user data in sub-frames subsequent to a sub-frame with the paging message, wherein the sub-frames subsequent to the sub-frame with the paging message are appropriate sub-frames subsequent to the paging message in a specified time period, and generating control information containing an identifier (ID) of the ETWS, wherein the control information contains resource information on a downlink shared channel (DL-SCH) that is assigned for the primary notification message of the ETWS; the base station sending the control information over a physical downlink control channel (PDCCH) and sending the primary notification message of the ETWS over the DL-SCH based on the control information; and after receiving the paging message containing the indication information of the ETWS message, the terminal immediately monitoring the PDCCH and detecting and analyzing the control information containing the identifier (ID) of the ETWS on the PDCCH to obtain the resource information contained in the control information, and receiving the primary notification message of the ETWS on corresponding resources of the DL-SCH based on the resource information, wherein the base station sends the control information over the PDCCH by putting the control information in a common search space within the PDCCH that is located within the sub-frame carrying the primary notification message of the ETWS or putting fixedly the control information in one or more control units within the PDCCH that is located within in the sub-frame carrying the primary notification message of the ETWS.
