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.
[0071] exist Figure 5 When an earthquake occurs, the UE supporting the ETWS function receives the ETWS main notification message paging message from the base station (see Figure 5 black part of ...
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.
[0075] exist Figure 6 When an earthquake occurs, the UE supporting the ETWS function receives the ETWS main notification message paging message from the base station (see Figure 6 black part of paging), UE immediately starts listening to SIB1 (see Figure 6 The black part of SI-1), SIB1 contains the scheduling informatio...
application example 3
[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.
[0079] exist Figure 7 When an earthquake occurs, the UE supporting the ETWS function receives the ETWS main notification message paging message from the base station (see Figure 7 black part of paging), UE immediately starts listening to SIB1 (see Figure 7The black part of SI-1), SIB1 contains the scheduling information of SIB10. The UE listens to the SIB10 information according to the sc...
