Problems solved by technology

Based on this network architecture, when a base station in E-UTRAN (also called an evolved Node B or eNB) sends an ETWS main notification message to a terminal (also called a user equipment, namely UE) through an air interface Uu, if the Paging the UE first, and then transmitting the ETWS main notification message to the terminal through the system message in the next system message modification cycle (generally exceeding 5s), will not meet the 4s delay requirement for the main notification message

[0042] The processing procedure of the method in this embodiment on the base station side is as follows: the base station sends a paging message (paging) carrying an ETWS message indication to the terminal, and immediately uses the pre-agreed resources of the downlink shared channel (DL-SCH) to send the ETWS main notification message, Includes basic and safety information. After receiving the paging message indicated by the ETWS message, all terminals receive the ETWS main notification message on the agreed resource.

[0043] In this embodiment, after receiving the paging message with the ETWS message indication, all terminals can receive the ETWS main notification message without the resource allocation instruction notification. The base station and the terminal need to agree in advance on the resources used to send the ETWS main notification message, which can reduce signaling overhead.

[0044] In this embodiment, the pre-reserved resource S (for the convenience of descrip...

[0063] In this embodiment, the base station carries the ETWS message indication and the basic information of the ETWS main notification message in the paging message sent to the terminal, and uses the pre-agreed resources on the DL-SCH to send the security information of the ETWS main notification message. The resource S used to send the security information can be agreed in advance according to the method disclosed in the first embodiment.

[0064] The processing flow of the base station side in this embodiment is as follows Figure 4 shown, including the following steps:

[0065] Step 410: After receiving the ETWS main notification message from the core network, the base station pages the terminal through a paging message, and the paging message carries the basic information of the ETWS message indication and the ETWS main notification message;

[0066] In this embodiment, the ETWS IMSI can also be used as the ETWS message indication, and the basic information of the ETWS m...

Abstract

The invention relates to an earthquake and tsunami warning system and a method for transmitting primary notification. A base station pages all terminals through paging messages comprising the indicating information of an earthquake and tsunami warning system ETWS messages, and sends the safety information of ETWS primary notification on a resource preappointed with the terminals; the basic information of the ETWS primary notification is carried in the paging messages and sent, or is sent on the preappointed resource; and after the terminals receive the paging messages comprising the indicatinginformation of the ETWS messages, the safety information of the ETWS primary notification is received on the preappointed resource, and the basic information of the ETWS primary notification is acquired in the paging messages, or is received on the preappointed resource. The earthquake and tsunami warning system can meet the requirement of the primary notification of the earthquake and tsunami warning system on the transmission time.

Description

technical field [0001] This patent relates to a method for a base station to transmit an Earthquake and Tsunami Warning System (ETWS: Earthquake and Tsunami Warning System) and a main notification message of the ETWS to a terminal. 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 early warning system, which is also referred to as the ETWS 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 public land mobile network (PLMN) 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 agenc...
