Method, device and eNB for stopping sending earthquake and tsunami warning system primary notification

Abstract

The invention provides a method, a device and eNB (Evolved Node B) for stopping sending an earthquake and tsunami warning system primary notification. The method comprises the following steps: receiving a warming message, when the warming message is the primary notification, sending the primary notification through a broadcasting system information block SIB 10 and starting a preset sending limit device; and when the preset conditions of the sending limit device are achieved, stopping broadcasting the SIB 10. The method, the device and the eNB have the benefits that the earthquake and tsunami warning system primary notification can be effectively stopped from being sent, and the primary notification is prevented from being continuously and improperly sent.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and evolved Node B (eNB) for stopping sending of an Earthquake and Tsunami Warning System (ETWS) main notification. Background technique [0002] ETWS provides a mechanism for sending warning notifications to user equipment (UE) such as mobile phones that need to be evacuated in the face of disasters such as earthquakes and tsunamis. UE users who receive warning notifications can know that danger is approaching or has occurred nearby , users can determine when and where to evacuate based on the warning notification. Currently, mobile phones are the closest medium to people, and ETWS uses this feature to help people avoid disasters or reduce losses caused by disasters. [0003] Currently, most networks adopt the Long Term Evolution (LTE) system, such as figure 1 As shown, the ETWS based on the LTE system generally includes: eNB, Mobility Man...

Problems solved by technology

[0012] However, although most operators today upgrade their networks to LTE, which is a quasi-fourth-generation (4th-Generation, 4G) mobile communication technology, they are still deploying in the era of third-generation (3rd-Generation, 3G) mobile communication technology CBE and CBC, such as the Japanese operator SoftBank; however, the CBE and CBC deployed in the 3G era do not support the write replacement method defined by the 3GPP protocol, that is, ETWS cannot normally use the write replacement method to stop broadcasting SIB10 and SIB11

[0013] In the LTE system, although the eNB can stop broadcasting SIB11 according to the period and number of information elements in the secondary notification, since there is no period and number of information elements in the primary notification, the eNB cannot stop broadcasting SIB10 according to the information element, which leads to the eNB being unable to Stop sending the main notification, which also means that users will receive warning messages that the earthquake and tsunami are coming for a long time after the earthquake and tsunami is over, causing panic among the public

[0014] Moreover, even if CBE and CBC support the write replacement method defined by the 3GPP protocol, if the earthquake and tsunami cause the line between the eNB and the upstream network element, such as the CBE, to be disconnected, then the eNB will not be able to receive the new write replacement alarm request message, causing the eNB to fail.
