Embodiment Construction

[0023] The present invention proposes that on the air interface, the basic message part of the main notification message uses paging messages to notify the terminal, and the security information part uses system message broadcast to send to the terminal. At the same time, in order to meet the delay requirement of 4 seconds, the system message is optimized to modify the paging process, Immediately paging the terminal in the current system message modification period without waiting for the next system message modification period.

[0024] The core idea of ​​the present invention is: after the base station receives the main notification message, it immediately pages all the terminals. The paging message carries the basic information part of the ETWS main notification message. Basic information of the notification message.

[0025] In this way, the delay requirement of 4 seconds can be met, and at the same time, it is not necessary to modify the scheduling and sending of system m...

Abstract

The invention discloses a method for sending a main notification message of an earthquake tsunami warning system ETWS, which comprises that: a base station sends a paging message to a terminal in a current system message modifying cycle after receiving the main notification message of the ETWS, wherein the paging message carries a basic information part of the main notification message of the ETWS; and the base station broadcasts the system message containing a safety information part of the main notification message of the ETWS in a next system message modifying cycle. The invention also discloses a method for receiving the main notification message of the ETWS, which comprises that: the terminal receives the paging message, reads the basic information part of the main notification message of the ETWS carried by the paging message; and the base station receives and reads the system message carrying the safety information part of the main notification message of the ETWS in the next system message modifying cycle, and verifies whether the basic information is true or not. The invention meets a delay requirement on the main notification message of the ETWS reaching the terminal within 4 seconds by only modifying the base station and the terminal slightly.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for sending and receiving 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 ETWS (Earthquake and Tsunami Waming System, Earthquake and Tsunami Early Warning System). By using this system, when an earthquake and tsunami natural disaster occurs, disaster-related information can be sent to users in a timely manner, thereby reducing the impact of the earthquake and tsunami natural disaster 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 P...
