Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a method for receiving and transmitting system messages of an earthquake and tsunami early warning system, which can be applied to the LTE system, allowing the terminal to receive ETWS system messages in a timely manner, and avoiding problems caused by the terminal processing multiple identical paging messages. The problem that the ETWS system message cannot be received by the terminal in time caused by the overlap of the reception time of the ETWS system message and SIB1

application example 1

[0069] Application example 1, this application example is a specific implementation of the above-mentioned first method.

[0070] Such as Figure 5 , where the squares with twill grids represent the messages (blocks) that the terminal needs to process, and the blank squares represent the messages (blocks) that the terminal ignores. The SIB that carries the main notification message of ETWS is SIB10, and SIB10 is mapped to SI-6. SI- The scheduling period of 6 is 640ms, and the offset is 40ms. The system message modification period of the cell is 5.12s, and the paging period is 320ms. The UE only reads the ETWS main notification message when it receives the ETWS main notification message paging for the first time within a system message modification period, that is, within 5.12s.

application example 2

[0073] Application example 2, this application example is a specific implementation of the above-mentioned second method.

[0074] Such as Figure 6 , where the squares with twill grids represent the messages (blocks) that the terminal needs to process, and the blank squares represent the messages (blocks) that the terminal ignores. The SIB that carries the main notification message of ETWS is SIB10, and SIB10 is mapped to SI-6. SI- The scheduling period of 6 is 320ms, and the offset is 40ms. The system information modification period of the cell is 5.12s, and the paging period is 640ms. In this way, the cycle of SI-6 is shorter than the paging cycle.

[0077] Application Example 3, this application example is a specific implementation of the above-mentioned third method.

[0078] Such as Figure 7 , where the squares with twill grids represent the messages (blocks) that the terminal needs to process, and the blank squares represent the messages (blocks) that the terminal ignores. The SIB that carries the main notification message of ETWS is SIB10, and SIB10 is mapped to SI-6. SI- The scheduling period of 6 is 640ms, and the offset is 40ms. The system message modification period of the cell is 5.12s, and the paging period is 320ms.

Abstract

The invention discloses a system message receiving and transmitting method of an earthquake and tsunami warning system (ETWS). The system message receiving method comprises the following steps: after a terminal successfully receives a paging message of an ETWS system message for the first time, reading the ETWS system message according to the scheduling information of the ETWS system message in asystem message block 1; within consecutive periods of time after the reading, when the terminal receives the paging message of the ETWS system message, not reading the ETWS system message, wherein the duration of the consecutive periods of time is not shorter than the duration from receiving the paging message of the ETWS system message to reading the ETWS system message. The invention can solve the problem that the ETWS system message cannot be received by the terminal because the terminal processes multiple same paging.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for receiving and transmitting system 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 Warning System, Earthquake and Tsunami 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 PLMN operato...
