Problems solved by technology

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

[0079] In this embodiment, the basic information and security information of the ETWS main notification message are scheduled and sent on the DL-SCH. The functional units related to the transmission of the main notification message of ETWS between the base station and the terminal are as follows: Figure 3A and Figure 3B shown, where:

[0080] Base stations include:

[0081] The first sending unit is used to paging the terminal at the paging occasion of the terminal and triggering the scheduling configuration unit through a paging message, the paging message carrying ETWS message indication information;

[0082] The scheduling configuration unit is used to schedule and configure the ETWS main notification message as user data on the subframe after the subframe where the paging message is located after being triggered, and generate the ETWS user identifier (ETWS ID) agreed in advance as the user identifier control information and trigger the second sending unit, the control...

[0107] In this embodiment, the basic information of the ETWS main notification message is carried in the paging message sent by the base station to the terminal, and only the security information of the ETWS main notification message is sent on the DL-SCH.

[0108] In this embodiment, the functional units of the base station and the terminal related to the transmission of the ETWS main notification message are as follows: Figure 5A and Figure 5B shown, where:

[0109] Base stations include:

[0110] The first sending unit is used to temporarily allocate an idle radio network temporary identity (RNTI, Radio Network Temporary Identity) as the ETWS ID, paging the terminal at the paging occasion of the terminal and triggering the scheduling configuration unit, and the paging message carries the ETWS message Indication information, basic information of ETWS main notification messages and temporarily assigned ETWS RNTI;

[0111] The scheduling configuration unit is used for sch...

Abstract

The invention discloses a method and a system for transmitting major notification messages of an earthquake and tsunami warning system. After paging a terminal through a paging message comprising ETWS message indicated information, a base station takes the major notification messages of the ETWS as user data of the ETWS to schedule and allocate the major notification messages, generates control information with a user identifier of the ETWS to send the control information on a PDCCH, and sends the major notification messages of the ETWS on a DL-SCH according to the control information; and the terminal monitors the PDCCH channel after receiving the paging message, receives and analyzes the control information after detecting the control information with the user identifier of the ETWS to acquire resource information in the control information, and receives the major notification messages of the ETWS on corresponding resources of the DL-SCH. Basic information of the major notification messages of the ETWS also can be carried in the paging message and sent, and security information is only sent on the DL-SCH. The invention also discloses a corresponding transmission system. The method and the system can meet the requirement of the major notification messages of the ETWS on sending time.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to a method and system for transmitting main notification messages of an Earthquake and Tsunami Warning System (ETWS: Earthquake and Tsunami 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 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, Public Land-Mobile Network) operator providing earthquake and tsunami warning services to users through the ETWS system. When a disaster event is abou...
