Embodiment Construction

[0028] In practical applications, when the eNB sends ETWS secondary notifications to the UE, the periodic transmission method can reduce bandwidth waste; however, there are problems with the reliability of only the periodic transmission method: the periodic transmission method only sends one round of SIB11 per cycle, It may happen that the eNB has finished sending the SIB11 but the UE has not received the paging message including the ETWS indication. Therefore, in the process of the eNB sending the ETWS secondary notification message to the UE, the eNB sends the paging message including the ETWS indication, the SIB1 including the SIB11 scheduling information, and the timing of sending the SIB11 are properly controlled.

[0029] In the embodiment of the present invention, when the alarm message is an ETWS secondary notification, before sending SIB11 in the first SIB11 sending cycle, send a paging message including ETWS indication and SIB1 including SIB11 scheduling information, ...

Abstract

The present invention provides a method for sending a secondary notification of an Earthquake and Tsunami Warning System (ETWS). The method comprises: in a default paging period, sending a paging message that comprises an ETWS instruction and a System Information Block Type 1 (SIB1), wherein the default paging period is a period before an SIB11 is sent in a sending period of the SIB11 and the SIB1 comprises SIB11 scheduling information; after the default paging period, separately sending the SIB1 once; and in the sending period of the SIB11, sending only the SIB11 but not the SIB1.

Description

technical field [0001] The present invention relates to information sending technology in the field of mobile communication, and in particular to a method, device and evolved Node B (eNB) for sending secondary notifications of Earthquake and Tsunami Warning System (ETWS). Background technique [0002] Currently, operators of the Public Land Mobile Network (PLMN) provide users with earthquake and tsunami warning services through the ETWS system based on the Long Term Evolution (LTE) network, such as figure 1 As shown, it is a schematic diagram of the network structure of the ETWS system of the PLMN operator through the LTE network in the prior art. The ETWS based on the LTE system usually includes: eNB, Mobility Management Entity (MME), Cell Broadcast Central (CBC) and Cell Broadcast Entity (CBE). [0003] Such as figure 2 As shown in FIG. 2 , it is a message interaction sequence diagram of triggering ETWS related network elements in the prior art. Wherein, the process of...
