Method for indicating primary notification message of earthquake and tsunami warning system

Abstract

The invention discloses a method for indicating a primary notification message of an earthquake and tsunami warning system, which comprises that: after receiving the primary notification message of the earthquake and tsunami warning system ETWS, a base station sends an ETWS indicating information sequence appointed with a terminal on a synchronous channel SCH; the ETWS indicating information sequence is used for indicating the existing ETWS message; and after judging that the received sequence is the ETWS indicating information sequence, the terminal receives the primary notification message of the ETWS on the appointed resource. Through the technical scheme provided by the invention, under the condition of modifying the base station and the UE a little, the method can realize the indication for the primary notification message of the ETWS. Through the information indication of the quick synchronous channel SCH, the time delay can be reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for indicating main notification messages of an earthquake and tsunami early warning system. Background technique [0002] In order to actively respond to natural disasters such as earthquakes and tsunamis, it is necessary to establish an Earthquake and Tsunami Warning System (ETWS: Earthquake and Tsunami Warning System). By using this system, when natural disasters such as earthquakes and tsunamis occur, disaster-related information can be sent to users in a timely manner, thereby reducing the impact of natural disasters such as earthquakes and tsunamis on human beings. [0003] figure 1 It is a network structure diagram of a PLMN (public land mobile network) operator providing earthquake and tsunami warning services to users through the ETWS system. When a disaster event is about to occur or occurs, the government or other institutions issue an alarm notification to the PLM...

AI Technical Summary

Problems solved by technology

On the air interface Uu interface (the interface between the base station and the UE), if the UE is paged, and then the ETWS main notification message is delivered to the UE through the system message in the next system message modification period (usually more than 5s), the main notification cannot be satisfied. Delay requirements for message 4s

There is a solution that directly adopts the paging message to carry the basic information part and the security information part of the main notification message. Since the content of the main notification message is relatively large, using this method will result in the segmentation of the main notification message and the impact on the existing paging message. The modification of call message structure and other issues, there are many modifications to the system
