[0056] Before introducing the technical solutions of the embodiments of this application, the relevant technologies will be introduced first.

[0057] In related technologies, non-terrestrial networks (NTNs), such as satellite networks, and terrestrial networks (TNs), such as terrestrial cellular networks, each have their own characteristics and complement each other. Satellite networks have wide coverage and strong disaster recovery capabilities, while terrestrial cellular networks have good network performance and mature deployment. To achieve the goal of mobile communication that allows "anyone, any time, any place" to communicate, terrestrial cellular networks mainly cover hotspot areas such as urban areas. For areas where terrestrial cellular networks cannot be deployed or where the cost of building such networks is too high, such as remote areas, deserts, oceans, and aviation, integrated space-ground networks are used to fill coverage gaps, achieving seamless global information service capabilities through integrated space-ground connectivity.

[0058] NTN networks and TN networks have significantly different coverage areas. For NTN networks such as high-Earth orbit satellite networks, each beam is assigned a Physical Cell Identity (PCI), with a typical beam radius of 120 km. One beam can cover multiple spectral positions. For NTN networks such as low-Earth orbit satellite networks, the typical beam radius is 26 km, which can be the typical spectral position radius. One beam can cover one spectral position. A cell for a low-Earth orbit satellite can be a single PCI for the entire satellite (all beams of a satellite share one PCI), or it can be a partial PCI for multiple beams. For terrestrial networks such as terrestrial cellular networks, the typical spacing between ground cells is 500 m to 2 km. Here, a spectral position is the smallest unit of granularity for satellite system coverage.

[0059] Currently, in emergency scenarios, the fifth-generation (5G) system broadcasts early warning information about disasters such as earthquakes and tsunamis throughout the entire cell via cell-level broadcast messages (SIB6, SIB7).

[0060] Table 1 illustrates SIB6. As shown in Table 1, SIB6 is the main notification message of the Earthquake and Tsunami Warning System (ETWS), used to provide core alarm information. The main information elements (IEs) included in SIB6 are messageIdentifier, serialNumber, and warningType. Among them, messageIdentifier represents the unique identifier of the message, used to distinguish different alarms; serialNumber represents the serial number, used to identify the updated version of the alarm; and warningType represents the type of emergency event.

[0061] Table 1

[0062]

[0063] Table 2 illustrates SIB7. As shown in Table 2, SIB7 is a secondary notification message in ETWS, used to provide detailed alert content. The main information elements (IEs) included in SIB7 are dataCodingScheme, messageIdentifier, serialNumber, warningMessageSegment, warningMessageSegmentNumber, and warningMessageSegmentType. Among them, dataCodingScheme represents the encoding scheme, defining the text encoding format; messageIdentifier represents the unique identifier of the message; serialNumber represents the serial number, used to identify the updated version of the alert; warningMessageSegment represents the detailed alert text, which can be sent in segments with multiple languages ​​or multiple parts of information; warningMessageSegmentNumber represents the segment number, for example, number 0 corresponds to the first segment, number 1 corresponds to the second segment, and so on; warningMessageSegmentType represents the segment type, including the initial segment, the middle segment, and the final segment.

[0065]

[0066] However, in satellite coverage scenarios, when the NTN network system broadcasts community-level disaster warning information, there is a problem of broadcasting too wide a range, which can cause unnecessary panic and seriously affect the user experience.

[0067] Based on this, in this application, first information is obtained; the first information includes the location information of at least one terminal within the coverage area of ​​the non-terrestrial network base station; based on the first information and the wave position information of the non-terrestrial network base station, the target wave position for broadcasting the warning information is determined; and the warning information is broadcast to the terminals within the target wave position.

[0068] See Figure 1 , Figure 1 This is a schematic diagram illustrating the implementation flow of the information processing method according to an embodiment of this application, applied to non-terrestrial network base stations, such as... Figure 1 As shown, the method includes steps 101 to 103:

[0069] Step 101: Obtain first information; the first information includes the location information of at least one terminal within the coverage area of ​​the non-terrestrial network base station.

[0070] It is understood that the non-terrestrial network base station can refer to a base station deployed on a non-terrestrial platform such as a satellite, high-altitude platform, or drone.

[0071] In practical applications, for at least one terminal within the coverage area of ​​the non-terrestrial network base station, it can send its coarse location information to the non-terrestrial network base station through the first parameter in the Radio Resource Control (RRC) signaling, so that the non-terrestrial network base station can directly parse the first parameter to obtain the coarse location information of the at least one terminal.

[0072] Based on this, in some embodiments, obtaining the first information includes:

[0073] Obtain first parameters sent by at least one terminal within the coverage area of ​​the non-terrestrial network base station; the first parameters include coarse location information of the terminal.

[0074] The first parameter is parsed to obtain the coarse location information of the terminal;

[0075] The coarse location information of the at least one terminal is used as the first information.

[0076] It is understood that the coarse location information can be understood as coarse-grained location information, that is, location information with an accuracy lower than a threshold, such as the location of the area where the terminal is located.

[0077] It is understood that the first parameter can refer to the access layer parameter in RRC signaling, such as the Information Element (IE) MeasResults.

[0078] Table 3 illustrates the first parameter. As shown in Table 3, the first parameter can be IE MeasResults, in which coarseLocationInfo-r17 carries the coarse location information of the terminal.

[0079] Table 3

[0080]

[0081]

[0082]

[0083] In practical applications, for at least one terminal within the coverage area of ​​the non-terrestrial network base station, its precise location information can be sent to the non-terrestrial network base station through the second parameter in the RRC signaling. Since the non-terrestrial network base station cannot directly obtain the precise location information of the terminal, it can pass the second parameter through to the network management system. The network management system can then parse the second parameter to obtain the precise location information of the terminal and send it to the non-terrestrial network base station.

[0084] Based on this, in some embodiments, obtaining the first information includes:

[0085] The acquisition of the first information includes:

[0086] The system obtains second parameters sent by at least one terminal within the coverage area of ​​the non-terrestrial network base station; the second parameters include the precise location information of the terminal.

[0087] Through the enhanced interface, the second parameters sent by the at least one terminal are transparently transmitted to the network management system, and the precise location information of the at least one terminal sent by the network management system is received; the precise location information is obtained by the network management system by parsing the second parameters.

[0088] The precise location information of the at least one terminal is used as the first information.

[0089] It is understood that the precise location information can be understood as high-precision location information, that is, location information with a precision higher than a threshold, such as the geographic coordinates of the terminal.

[0090] It is understood that the enhanced interface can refer to the enhanced southbound interface of the network management system. Since the non-terrestrial network base station cannot directly obtain the terminal's precise location information, it can transparently transmit the second parameter to the network management system. That is, the non-terrestrial network base station does not parse the second parameter, while the network management system parses the second parameter to obtain the terminal's precise location information and returns it to the non-terrestrial network base station. To enable the transmission of the terminal's precise location information between the non-terrestrial network base station and the network management system, the southbound interface of the network management system—that is, the interface between the network management system and the non-terrestrial network base station—is enhanced. This enhanced southbound interface enables the transmission of the terminal's precise location information between the non-terrestrial network base station and the network management system.

[0091] It is understood that the network management system can send the terminal's precise location information to the non-terrestrial network base station through a first message; wherein, the first message may contain at least one of a first field, a second field, a third field, a fourth field, and a fifth field, wherein the first field indicates that the terminal's precise location information is being transmitted, the second field is a required field used to fill in information such as the terminal's identifier, the third field is an optional field used to fill in information such as the terminal's location precision, the fourth field indicates that the terminal's precise location information is being transmitted using a decimal string, and the fifth field indicates that the terminal's precise location information, such as latitude and longitude coordinates, is being transmitted.

[0092] It is understandable that the second parameter could refer to a higher-level parameter in RRC signaling, such as the Information Element (IE) CommonLocationInfo.

[0093] Table 4 illustrates the second parameter. As shown in Table 4, the second parameter can be IECommonLocationInfo, in which gnss-TOD-msec-r16 is used to transmit the precise location information of the terminal.

[0094] Table 4

[0095]

[0096] Step 102: Based on the first information and the wave position information of the non-terrestrial network base station, determine the target wave position of the warning information to be broadcast.

[0097] It is understood that the beam position information of the non-terrestrial network base station refers to the information of the ground coverage area formed by the beam of the non-terrestrial network base station in a certain direction. One beam can cover multiple beam positions, or one beam can cover one beam position, and one beam position corresponds to one ground coverage area.

[0098] It is understood that the wavelength information of the non-terrestrial network base station can be pre-planned.

[0099] In practical applications, considering that NTN network systems broadcasting cell-level disaster warning information in satellite coverage scenarios may result in an excessively large broadcast range, leading to unnecessary panic and severely impacting user experience, this application proposes that the non-terrestrial network base station can combine the location information of at least one terminal within its coverage area with its own wave position information to determine which wave positions to broadcast the warning information to. By broadcasting information at the wave position level, accurate broadcasting of the warning information can be achieved, avoiding the problem of poor user experience caused by an excessively large broadcast range.

[0100] Based on this, in some embodiments, determining the target wavelength of the warning information to be broadcast, according to the first information and the wavelength information of the non-terrestrial network base station, includes:

[0101] Based on the wave position information of the non-terrestrial network base station, the first distance between the area corresponding to each wave position of the non-terrestrial network base station and the risk area is determined, and multiple first distances are obtained.

[0102] For each of the first distances, when the corresponding first distance is less than or equal to the safety distance, the wave position corresponding to the corresponding first distance is taken as the first wave position, and at least one first wave position is obtained;

[0103] For each of the first wave positions, when it is determined from the first information that there is a terminal located at the corresponding first wave position among the at least one terminal, the corresponding first wave position is taken as the target wave position for broadcasting the warning information.

[0104] Here, determining the first distance between the area corresponding to each wave position of the non-terrestrial network base station and the risk area may include: determining the first distance between the center of the area corresponding to each wave position and the center of the risk area; wherein, the center of the area corresponding to the wave position may refer to the location of the center point of the area corresponding to the wave position, and the center of the risk area may refer to the location of the center point of the risk area, wherein the location of the center point may be preset according to the actual situation, the risk area includes but is limited to the risk area of ​​disasters such as earthquakes and tsunamis, and the safe distance may be a preset distance value according to the actual situation.

[0105] Here, by combining risk areas, safe distances, and wave position information, it is determined which wave positions require the issuance of early warning information.

[0106] Specifically, this can include the following situations:

[0107] In the first scenario, based on the location information of at least one terminal within the coverage area of ​​the non-terrestrial network base station, if a terminal (user) within the coverage area of ​​the non-terrestrial network base station is located within a wave position (i.e., the first wave position) at a safe distance, then a warning message needs to be sent to the terminal in that wave position.

[0108] Here, for each first wave position, based on the location information of each terminal and the geographical location information of the area corresponding to the first wave position, it is determined whether there is a terminal located in the corresponding first wave position among the at least one terminals. If there is a terminal located in the corresponding first wave position among the at least one terminals, the corresponding first wave position is taken as the target wave position for broadcasting warning information, and warning information is subsequently sent to the terminals within the target wave position.

[0109] In the second scenario, if there are no terminals (users) within the coverage area of ​​the non-terrestrial network base station within the safe distance of the first wave position (i.e., the first wave position), then there is no need to send warning information to the terminals in that wave position.

[0110] Here, for each of the first wave positions, based on the location information of each terminal and the geographical location information of the area corresponding to the first wave position, it is determined whether there is a terminal located in the corresponding first wave position among the at least one terminals. If there is no terminal located in the corresponding first wave position among the at least one terminals, then no warning information will be sent to the terminals in that wave position.

[0111] Step 103: Broadcast warning information to terminals within the target wavelength range.

[0112] It is understandable that for all wave positions of the non-terrestrial network base station, the target wave position needs to broadcast warning information, while other wave positions do not need to broadcast warning information. Therefore, wave position-level system information blocks can be broadcast, with different broadcast information for different wave positions, in order to achieve accurate broadcast warning information and improve broadcast efficiency.

[0113] In practical applications, when the beam of the non-terrestrial network base station covers the target beam position, the non-terrestrial network base station broadcasts a beam position-level system information block, which contains early warning information to achieve accurate broadcasting of early warning information.

[0114] Based on this, in some embodiments, broadcasting the warning information to terminals within the target wavelength includes:

[0115] Broadcast waveband level system information block;

[0116] The waveband-level system information block is sent by the non-terrestrial network base station to the terminal within the target waveband, and the waveband-level system information block includes a first system information block and / or a second system information block; the first system information block and / or the second system information block carries the warning information.

[0117] It is understood that the first system information block may refer to the primary notification message of the Earthquake and Tsunami Warning System (ETWS), namely SIB6, which is used to provide core warning information, and the second system information block may refer to the secondary notification message of the Earthquake and Tsunami Warning System (ETWS), namely SIB7, which is used to provide detailed warning content.

[0118] In practical applications, when the beam of the non-terrestrial network base station covers other beam positions besides the target beam position, the non-terrestrial network base station broadcasts a beam position-level system information block. This beam position-level system information block does not contain early warning information, so as to save unnecessary early warning broadcasts and thus improve broadcast efficiency.

[0119] Based on this, in some embodiments, the method further includes:

[0120] Broadcast waveband level system information block;

[0121] The waveband-level system information block is sent by the non-terrestrial network base station to terminals in other wavebands besides the target waveband, and the waveband-level system information block does not contain the warning information.

[0122] It is understood that the phrase "not including the warning information" can be interpreted as not including the first system information block and / or the second system information block; wherein, the first system information block may refer to the main notification message of the Earthquake and Tsunami Warning System (ETWS), namely SIB6, which is used to provide core warning information, and the second system information block may refer to the secondary notification message of the Earthquake and Tsunami Warning System (ETWS), namely SIB7, which is used to provide detailed warning content.

[0123] The embodiments of this application have the following technical advantages:

[0124] (1) By combining the location information of at least one terminal within the coverage area of ​​the non-terrestrial network base station and the wave position information of the non-terrestrial network base station, the target wave position of the warning information to be broadcast is determined, and the warning information is broadcast to the terminal within the target wave position, thereby achieving accurate broadcasting of the warning information and avoiding the problem of poor user experience caused by excessive broadcast range in related technologies.

[0125] (2) In emergency scenarios, by sending waveband-level broadcast information, accurate broadcasting of early warning information such as earthquakes and tsunamis can be carried out. Since the broadcast information of different wavebands is different, the early warning information can be sent more accurately, thereby improving the NTN user experience.

[0126] See Figure 2 , Figure 2 This is a schematic diagram illustrating the implementation flow of the information processing method according to an embodiment of this application. It is applied to a terminal, where the terminal is any one of at least one terminals within the coverage area of ​​a non-terrestrial network base station, such as... Figure 2 As shown, the method includes step 201:

[0127] Step 201: Send the location information of the terminal to the non-terrestrial network base station; wherein, the location information of at least one terminal within the coverage area of ​​the non-terrestrial network base station is used by the non-terrestrial network base station in conjunction with the wave position information of the non-terrestrial network base station to determine the target wave position of the warning information to be broadcast, and broadcast the warning information to the terminals within the target wave position.

[0128] It is understood that the non-terrestrial network base station can refer to a base station deployed on a non-terrestrial platform such as a satellite, high-altitude platform, or drone.

[0129] In practical applications, for at least one terminal within the coverage area of ​​the non-terrestrial network base station, it can send its coarse location information to the non-terrestrial network base station through the first parameter in the RRC signaling, so that the non-terrestrial network base station can directly parse the first parameter to obtain the coarse location information of the at least one terminal.

[0130] Based on this, in some embodiments, sending the terminal's location information to the non-terrestrial network base station includes:

[0131] A first parameter is sent to the non-terrestrial network base station; the first parameter includes the coarse location information of the terminal; wherein, the first parameter is used by the non-terrestrial network base station to parse and obtain the coarse location information of the terminal.

[0132] It is understood that the coarse location information can be understood as coarse-grained location information, that is, location information with an accuracy lower than a threshold, such as the location of the area where the terminal is located.

[0133] It is understood that the first parameter can refer to the access layer parameter in RRC signaling, such as IEMeasResults.

[0134] In practical applications, for at least one terminal within the coverage area of ​​the non-terrestrial network base station, its precise location information can be sent to the non-terrestrial network base station through the second parameter in the RRC signaling. Since the non-terrestrial network base station cannot directly obtain the precise location information of the terminal, it can pass the second parameter through to the network management system. The network management system can then parse the second parameter to obtain the precise location information of the terminal and send it to the non-terrestrial network base station.

[0135] Based on this, in some embodiments, sending the terminal's location information to the non-terrestrial network base station includes:

[0136] The second parameter is sent to the non-terrestrial network base station; the second parameter includes the precise location information of the terminal; wherein, the second parameter is used by the non-terrestrial network base station to transmit the information transparently to the network management system through the enhanced interface, and to receive the precise location information of the terminal sent by the network management system; the precise location information is obtained by the network management system by parsing the second parameter.

[0137] It is understood that the precise location information can be understood as high-precision location information, that is, location information with a precision higher than a threshold, such as the geographic coordinates of the terminal.

[0138] It is understood that the enhanced interface can refer to the enhanced southbound interface of the network management system. Since the non-terrestrial network base station cannot directly obtain the terminal's precise location information, it can transparently transmit the second parameter to the network management system. That is, the non-terrestrial network base station does not parse the second parameter, while the network management system parses the second parameter to obtain the terminal's precise location information and returns it to the non-terrestrial network base station. To enable the transmission of the terminal's precise location information between the non-terrestrial network base station and the network management system, the southbound interface of the network management system—that is, the interface between the network management system and the non-terrestrial network base station—is enhanced. This enhanced southbound interface enables the transmission of the terminal's precise location information between the non-terrestrial network base station and the network management system.

[0139] It is understandable that the second parameter could refer to a higher-level parameter in the RRC signaling, such as IECommonLocationInfo.

[0140] It should be noted that the process by which the non-terrestrial network base station determines the target wave position of the warning information to be broadcast has been described above and will not be repeated here.

[0141] It is understandable that for all wave positions of the non-terrestrial network base station, the target wave position needs to broadcast warning information, while other wave positions do not need to broadcast warning information. Therefore, wave position-level system information blocks can be broadcast, with different broadcast information for different wave positions, in order to achieve accurate broadcast warning information and improve broadcast efficiency.

[0142] In practical applications, when the beam of the non-terrestrial network base station covers the target beam position, the non-terrestrial network base station broadcasts a beam position-level system information block, which contains early warning information to achieve accurate broadcasting of early warning information.

[0143] Based on this, in some embodiments, the terminal is a terminal within the target wavelength, and the method further includes:

[0144] Receive the wavelet-level system information block broadcast by the non-terrestrial network base station; wherein the wavelet-level system information block includes a first system information block and / or a second system information block; the first system information block and / or the second system information block carries early warning information.

[0145] It is understood that the first system information block may refer to the primary notification message of the Earthquake and Tsunami Warning System (ETWS), namely SIB6, which is used to provide core warning information, and the second system information block may refer to the secondary notification message of the Earthquake and Tsunami Warning System (ETWS), namely SIB7, which is used to provide detailed warning content.

[0146] In practical applications, when the beam of the non-terrestrial network base station covers other beam positions besides the target beam position, the non-terrestrial network base station broadcasts a beam position-level system information block. This beam position-level system information block does not contain early warning information, so as to save unnecessary early warning broadcasts and thus improve broadcast efficiency.

[0147] Based on this, in some embodiments, the terminal is a terminal in a wave position other than the target wave position, and the method further includes:

[0148] Receives a wavelet-level system information block broadcast by the non-terrestrial network base station; wherein the wavelet-level system information block does not contain early warning information.

[0149] It is understood that the phrase "not including the warning information" can be interpreted as not including the first system information block and / or the second system information block; wherein, the first system information block may refer to the main notification message of the Earthquake and Tsunami Warning System (ETWS), namely SIB6, which is used to provide core warning information, and the second system information block may refer to the secondary notification message of the Earthquake and Tsunami Warning System (ETWS), namely SIB7, which is used to provide detailed warning content.

[0150] The embodiments of this application have the following technical advantages:

[0151] (1) By combining the location information of at least one terminal within the coverage area of ​​the non-terrestrial network base station and the wave position information of the non-terrestrial network base station, the target wave position of the warning information to be broadcast is determined, and the warning information is broadcast to the terminal within the target wave position, thereby achieving accurate broadcasting of the warning information and avoiding the problem of poor user experience caused by excessive broadcast range in related technologies.

[0152] (2) In emergency scenarios, by sending waveband-level broadcast information, accurate broadcasting of early warning information such as earthquakes and tsunamis can be carried out. Since the broadcast information of different wavebands is different, the early warning information can be sent more accurately, thereby improving the NTN user experience.

[0153] See Figure 3, Figure 3 This is a schematic diagram illustrating the specific implementation flow of the information processing method in the embodiments of this application, such as... Figure 3 As shown, steps 301 to 304 are included:

[0154] Step 301: The terminal (User Equipment) accesses the NTN cell.

[0155] Step 302: Non-terrestrial network base stations, i.e., NTN base stations, obtain the location information of terminals (UEs) within their coverage area.

[0156] Here, the NTN base station knows the wavelength information within its coverage area.

[0157] Here, the following two methods can be used;

[0158] In the first method, the terminal (UE) reports its own coarse location information (or describes it as coarse-grained location information, such as accuracy within 2km) through the MeasResults parameter in the RRC message;

[0159] In the second method, the terminal (UE) sends its precise location information to the NTN base station (e.g., gNB-NTN) via the CommonLocationInfo parameter in the RRC signaling. Since the NTN base station cannot directly obtain the terminal's precise location information, the NTN base station (gNB-NTN) transparently transmits this parameter to the network management system (NTN Operation and Maintenance Management (OAM)). The network management system (NTN OAM) then parses the parameter to obtain the terminal's precise location information. By enhancing the southbound interface of the network management system (NTN OAM), i.e., the interface between the network management system and the NTN base station, the precise location information of the terminal (UE) can be sent to the NTN base station (gNB-NTN) in a pre-agreed format through the enhanced southbound interface of the network management system.

[0160] Step 303: The NTN base station determines the target wavelength of the warning information to be broadcast based on the location information of the terminal (UE) within its coverage area and the wavelength information of the NTN base station.

[0161] Here, the NTN base station needs to determine which wave positions to send warning information to. Specifically, based on the wave position information of the NTN base station, a first distance between the area corresponding to each wave position of the NTN base station and the risk area is determined, resulting in multiple first distances. For each first distance, when the corresponding first distance is less than or equal to the safe distance, the wave position corresponding to the corresponding first distance is taken as the first wave position, resulting in at least one first wave position. For each first wave position, when it is determined based on the first information that there is a terminal located in the corresponding first wave position among the at least one terminal, the corresponding first wave position is taken as the target wave position to be broadcast warning information. That is, by combining the risk area, the safe distance, and the wave position information, it is determined which wave positions need to send warning information. Specifically, based on the UE's location information, if it is determined that the wave position involved in the safe distance contains a terminal (user) within the coverage area of ​​the non-terrestrial network base station, then warning information needs to be sent to the terminal in that wave position. Based on the UE's location information, if it is determined that the wave position involved in the safe distance does not contain a terminal (user) within the coverage area of ​​the non-terrestrial network base station, then warning information does not need to be sent to the terminal in that wave position.

[0162] Step 304: The NTN base station generates a wavelength-level system information block and broadcasts the wavelength-level system information block.

[0163] Here, the wave position, i.e., the system information block, can refer to the wave position level SIB1, wherein the wave position level SIB1 of different wave positions includes the required SIBx as needed, and SIBx can refer to SIB6 and / or SIB7.

[0164] See Figure 4 , Figure 4 This is a schematic diagram of the wave position in an embodiment of this application, as shown below. Figure 4As shown, the non-terrestrial network base station is a gNB-NTN base station. Assume the terminals within the coverage area of ​​the gNB-NTN base station are UE1 and UE2. UE1 and UE2 are respectively connected to the NTN cell. The gNB-NTN base station knows the wave position information of 8 wave positions within its coverage area. One beam covers one wave position. UE1 and UE2 report their respective location information to the gNB-NTN base station. Based on the location information of UE1 and UE2, and its own wave position information, the gNB-NTN base station determines the first distance between the area corresponding to each wave position and the risk area (tsunami occurrence area), obtaining multiple first distances. For each first distance, when the corresponding first distance is less than or equal to the safe distance, the wave position corresponding to the corresponding first distance is taken as the first wave position, obtaining at least one first wave position, assumed to be wave position 3, wave position 4, and wave position 5. For each first wave position, when it is determined that there is a terminal located in the corresponding first wave position among UE1 and UE2, the first wave position is taken as the target wave position for broadcasting the warning information. Wave position 4 includes UE2. Wavelength 4 indicates that wavelength 4 requires an earthquake and tsunami warning (ETWS). The other eight wavelengths do not require warnings. It should be noted that wavelengths 3 and 5 are also within the safe distance, but since there are no NTN users within these wavelengths, no warnings need to be sent. When the gNB-NTN base station's beam covers the target wavelength 4, the gNB-NTN base station sends a wavelength-level SIB1. This SIB1 instructs the scheduling resources of SIB6 and / or SIB7. All users within the specified position, i.e., UE2, obtain SIB6 and / or SIB7 by demodulating SIB1. SIB6 carries the core warning information, and SIB7 carries the detailed warning content. When the beam of the gNB-NTN base station covers other beam positions besides the target beam position, i.e., beam position 4, such as beam position 6, the gNB-NTN base station sends a beam position-level SIB1. This SIB1 does not contain warning information, i.e., there is no scheduling information for SIB6 and no scheduling information for SIB7. All users within this beam position, i.e., UE1, will not receive warning information.
