在日本，通过使用地震和海啸警报系统（ETWS），将诸如地震早期警报和海啸警报的早期警报广播到蜂窝电话[1]。LTE装置（UE：用户设备）的连接性取决于充当与因特网的中继的LTE基站（演进节点B：eNB）。因此，很难在大规模灾害期间发出预警。
In Japan, early warnings such as the earthquake early warning and the tsunami warning are broadcast to cellular phones by using the Earthquake and Tsunami Warning System (ETWS) [1]. The connectivity of a LTE device (UE: user equipment) depends on the LTE base station (evolved Node B: eNB) which acts as a relay with the Internet. Therefore it is difficult to broadcast early warnings during large-scale disasters.
