[0119] In some embodiments, the second network element 1032 is, for example, a Mobile Management Entity (MME) or an Access Management Function (AMF).

[0120] In some embodiments, the MME is used for mobility management, authentication, and security control of the terminal, as well as bearer control. The AMF is used for user registration and authentication, access control, mobility management, and security key management of the terminal.

[0121] In some embodiments, the first network element 1031 can be independent of the core network device 103.

[0122] In some embodiments, the first network element 1031 may be part of the core network device 103.

[0123] In some embodiments, the second network element 1032 may be independent of the core network device 103.

[0124] In some embodiments, the second network element 1032 may be part of the core network device 103.

[0125] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0126] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0127] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0128] The Public Warning System (PWS) provides a one-stop service that allows networks to distribute alarm information based on public authorization. PWS can distribute information from the Earthquake and Tsunami Warning System (ETWS), the Commercial Mobile Alert System (CMAS), the Korean Public Alert System (KPAS), and the European Public Warning System (EU-Alert). PWS supports the distribution of ETWS, CMAS (also known as WEA), KPAS, and EU-Alert alarm information in GSM, UMTS, E-UTRAN, and NG RAN. Alarm information delivery is similar to Cell Broadcast Service (CBS), allowing a large number of unacknowledged alarm messages to be broadcast to terminals within a specific area.

[0129] CBS messages are broadcast to defined geographic areas, called cell broadcast areas. These areas may consist of one or more cells, or they may be the entire PLMN area. Each CBS message is assigned its own geographic coverage area according to the agreement between the information provider and the PLMN. CBS messages may originate from a Cell Broadcast Entity (CBE). Then, based on the CBS coverage requirements, the CBS message is sent from the CBE to the cell.

[0130] CBS messages are broadcast cyclically within the cell. The frequency with which CBS messages are repeated will depend on the information they contain; for example, dynamic information (such as road traffic information) may require more frequent transmission than weather information. The repetition period will also be affected by mobile phones hoping to quickly cross the cell to receive CBS messages. If the mobile station (MS) / terminal is connected to the packet switch (PS) domain and no data is currently being transmitted, the MS or terminal should be able to receive the message.

[0131] Figure 1B illustrates the network architecture of an LTE system. In this system, the MME connects to the eNB and the CBC. The CBC connects to the Cell Broadcast Entity (CBE). The CBE can operate independently of the communication network. For example, the CBE can be an application server. The CBE can be used to provide broadcast alarm information and / or alarm-related attributes. For example, alarm-related attributes include, but are not limited to, one or more of the following: message source, message type, and affected area.

[0132] Figure 1C shows a schematic diagram of the network architecture of a 5G system. In this system, the AMF is connected to both the RAN and CBCF. The CBCF is connected to the CBE. The RAN is connected to the terminal.

[0133] The Cell Broadcast Center (CBC) is part of the core network and connects to the MME via the SBc reference point. The CBC may connect to multiple MMEs and multiple CBEs. The CBC is responsible for managing CBS messages.

[0134] CBCF is a network function in the 5G core network. CBCF can connect to multiple AMFs and multiple CBEs. CBCF is responsible for managing CBS messages.

[0135] In the above architecture, the CBC / CBCF determines the Warning Area list information. The Warning Area list indicates the areas where warning information needs to be broadcast. The Warning Area list should be a list of cell IDs, a Tracking Area Identifier (TAI) list, or one or more Emergency Area Identifiers (IDs). An Emergency ID indicates the area affected by an emergency and may consist of multiple cells. The Warning Area list is only available to the eNB and / or gNB. The eNB and / or gNB are configured with the TAI and cell IDs they serve, as well as the Emergency Area IDs to which they belong. The eNB and / or gNB check whether the information in the Warning Area list matches these IDs to identify the cells to which the warning information should be distributed.

[0136] In some cases, EPS / 5GS with NTN access (e.g., satellite access) should support Warning Messages (PWS). For example, alarm information can be broadcast via Narrow Band Internet of Things (NB-IoT) NTN access. When using terrestrial cellular networks for PWS services, the corresponding Warning Area is represented using a cell list, a Tracking Area Identifier (TAI) list, or an Emergency Area ID (Emergency Area ID) (which is also composed of cells). Since the cell range or TA range in non-terrestrial networks (e.g., satellite networks) is much larger than the planned cell or TA range in terrestrial networks, continuing to use the existing warning area list definition will not meet the needs for implementing PWS in areas smaller than a cell or TA. That is, NTN systems can provide a larger coverage area compared to terrestrial network coverage. For example, in some cases, the expected alarm area is anticipated to be smaller than a single cell / TA in the NTN access network, and the current warning area list definition cannot meet this requirement. Therefore, enhancements are needed to notify the required alarm areas.

[0137] Figure 2A is an interactive schematic diagram of an information processing method according to an embodiment of the present disclosure. This disclosure relates to an information processing method that can be executed by the communication system shown in Figure 1A. As shown in Figure 2A, the method includes:

[0138] S2101: The first network device sends the first information to the second network device.

[0139] In some embodiments, both the first network device and the second network device are core network devices.

[0140] In some embodiments, the first network device may be a CBC or a CBCF. In some embodiments, the second network device may be an MME or an AMF. For example, if the first network device is a CBC, then the second network device may be an MME. Also for example, if the first network device is a CBCF, then the second network device may be an AMF. In some embodiments, the second network device may be any core network device that manages the broadcast area. In other embodiments, the second network device may also be a core network device that has established connections with access network devices within the broadcast area.

[0141] In some embodiments, the second network device receives first information sent by the first network device through an inter-device interface.

[0142] In some embodiments, the second network device receives first information sent by the first network device based on a service. In some embodiments, the second network device receives the first information from the first network device when the alarm system needs to distribute alarm information.

[0143] In some embodiments, the first information may be any information different from the cell identifier and / or tracking area identifier.

[0144] In some embodiments, the first information does not include the cell identifier and the tracking area identifier.

[0145] In some embodiments, the first information includes at least one of the following:

[0146] The geographical location information of the broadcast area;

[0147] The address information of the broadcast area;

[0148] The coordinate information of the broadcast area;

[0149] The coordinates of the center point of the broadcast area and the radius of the broadcast area.

[0150] In some embodiments, the first information may be geographic information. For example, the first information may be geographic location information. This geographic location information may indicate various information related to a geographic location.

[0151] In some embodiments, the first information may further include address information, such as a specific city and district. In some embodiments, the address information may also be referred to as administrative region information or administrative address information, etc.

[0152] In some embodiments, the first information includes coordinate information, and the coordinates corresponding to the coordinate information can be a custom coordinate system or a world coordinate system, etc.

[0153] In some embodiments, the first information includes at least one coordinate; the at least one coordinate is used to determine the broadcast area.

[0154] In some embodiments, the first information includes: at least one first coordinate; the at least one first coordinate is the boundary coordinate of the first region.

[0155] In some embodiments, the first information may include coordinate information and radius information, where the radius indicates the radius of the broadcast area. Thus, by combining the coordinates of the center point and the radius information, the extent of the broadcast area can be accurately determined.

[0156] In some embodiments, the broadcast area may include one or more cells. In some embodiments, the broadcast area may include one or more tracking areas.

[0157] In some embodiments, the area of ​​the broadcast area may be smaller than a cell, or the broadcast area may be smaller than a tracking area, or the broadcast area may be an overlapping area of ​​multiple cells, or the broadcast area may be an overlapping area of ​​multiple tracking areas.

[0158] In some embodiments, the broadcast area may include a portion of a cell, for example, a portion of an NTN cell.

[0159] In some embodiments, the broadcast area may be an area for sending various broadcast messages.

[0160] In some embodiments, the broadcast area is a broadcast area for alarm information. In some embodiments, the broadcast area may be an emergency area, where terminals within the emergency area need to listen for alarm information. This alarm information may include, but is not limited to, information from ETWS, CMAS, KPAS, and / or EU-Alert systems.

[0161] In some embodiments, the alarm information may include one or more of the following: weather alarm information, earthquake alarm information, road traffic alarm information, public safety warning information, and epidemic prevention information.

[0162] In some embodiments, the first information is used to indicate a broadcast area. The first information can be used to determine the cell and / or tracking area associated with the broadcast area. Exemplarily, the first information can be used to indicate a first area separately.

[0163] In some embodiments, the cells associated with a broadcast area may include: cells wholly contained within the broadcast area and / or cells partially contained within the broadcast area. For example, cell A is partially contained within the broadcast area. Cell A includes area 1 and area 2, where area 1 is located within the broadcast area and area 2 is located outside the broadcast area.

[0164] In some embodiments, the tracking area associated with the broadcast area may include: a tracking area wholly contained within the broadcast area and / or a tracking area partially contained within the broadcast area. For example, tracking area A is partially contained within the broadcast area. Tracking area A includes area A and area B, where area A is located within the broadcast area and area B is located outside the broadcast area.

[0165] In some embodiments, the first information and the third information are used together to indicate a broadcast area. Exemplarily, the first information and the third information have different information formats. The third information includes at least one of a cell identifier and a tracking area identifier.

[0166] In some embodiments, the first information is not limited to any of the above-mentioned information. In some embodiments, the first information may also be referred to as broadcast area information.

[0167] In some embodiments, the first network device may send first information to the second network device through an interface between the first network device and the second network device.

[0168] In some embodiments, the first network device may send first information and / or alarm information to the second network device. In some embodiments, the first information may carry a write-replace warning request to the second network device.

[0169] In some embodiments, a first network device can send first information to a second network device by invoking a service. When the first network device sends first information to the second network device, the corresponding second network device will receive the first information sent by the first network device.

[0170] In some embodiments, the second network device stores the first information locally after receiving the first information.

[0171] In some embodiments, after receiving the first information, the second network device sends a first response to the first network device. This first response indicates that the network device has received the first information. In some embodiments, the first network device receiving the first information may indicate that the second network device has begun distributing alarm information. It is worth noting that sending a second response may be an optional step. In some embodiments, if the first response is a message that needs to be sent, the first network device receives the first response within a first time period after sending the first information. If the first network device does not receive the first response within the first time period, it can determine that the second network device has not successfully received the first information. In this case, the first network device may repeatedly send the first information to the second network device. Alternatively, the first network device may reselect a second network device. The reselected second network device may connect to an access network device within the broadcast area.

[0172] In some embodiments, a first network device may receive a first request from a fourth network device. The first request is used to request the broadcast of alarm information. Exemplarily, the fourth network device may be a server such as a CBE (Callable Emergency Broadcast) requesting the sending of alarm information. In some embodiments, the first request may be an Emergency Broadcast Request. After receiving the request from the fourth network device, the first network device may determine either first information or a combination of first and third information. In some embodiments, after receiving the first request, the first network device may send the first information to a second network device, or send both first and third information to the second network device.

[0173] In some embodiments, the first network device may send a configuration based on local alarm information to the second network device, sending a first message or a combination of first and third messages, not limited to sending the first message or sending the first and third messages to the second network device after receiving the first request.

[0174] In some embodiments, after obtaining the first information, the first network device directly sends the first information to the second network device or sends the first information and the third information to the second network device.

[0175] In some embodiments, the first network device determines whether the access type of the broadcast area includes NTN access. If the access type of the broadcast area includes NTN access, the first network device sends first information to the second network device.

[0176] In some embodiments, when the access type of the broadcast area does not include NTN access, the first network device does not send the first information to the second network device.

[0177] In some embodiments, when the access type of the broadcast area does not include NTN access, the first network device sends third information to the second network device.

[0178] In some embodiments, the first network device determines second information based on first information. Exemplarily, the second information is used to indicate cells and / or tracking areas associated with (or encompassed by) the broadcast area.

[0179] In some embodiments, the first network device determines the second network device before sending the first information to the second network device.

[0180] In some embodiments, the first network device determines the second network device based on first information. For example, the first network device stores information related to the geographical areas governed by candidate devices for the second network device. In this case, the first network device can directly determine the second network device based on the first information and the information related to the geographical areas governed by each candidate device.

[0181] In some embodiments, the first network device determines the second network device based on the second information. Since the second information indicates a cell or tracking area associated with (including) a broadcast area, and since the second network device typically stores information related to network areas governed by alternative devices, the second network device can be determined based on the second information and the information related to network areas governed by alternative devices.

[0182] In some embodiments, the first network device determines the second network device based on the second information.

[0183] In some embodiments, the second information is used to indicate at least one of the cells and tracking areas associated with the broadcast area.

[0184] In some embodiments, the second information is used to indicate at least one of all cells and all tracking areas associated with the broadcast area.

[0185] In some embodiments, the first network device determines the second network device based on first information and third information. The third information is used to indicate at least one of the partial cells associated with the broadcast area and the partial tracking area associated with the broadcast area.

[0186] In some embodiments, the step of determining the second network device is optional, specifically because the first network device can determine all candidate network devices as the second network device. The candidate device is connected to the first network device. The candidate device can be a network device capable of receiving the first information, or a network device that needs to use the first information. For example, assuming the first network device is a CBC, all MMEs connected to the CBC can be assumed to be the second network device. As another example, assuming the first network device is a CBCF, all AMFs connected to the CBCF can be assumed to be the second network device.

[0187] In some embodiments, the first network device sends first information and third information to the second network device. For example, where the first information and third information are used together to indicate a broadcast area, the first network device sends the first information and third information to the second network device.

[0188] In some embodiments, where the first information specifically indicates the broadcast area, the first network device can send the first information separately to the second network device.

[0189] In some embodiments, if the second network device determines that it has obtained the second information based on the first information, the second network device may also send the second information to the third network device. If the second information is sent to the second network device, the second network device does not need to determine the second information again.

[0190] S2102: The second network device sends the first information to the third network device.

[0191] In some embodiments, the third network device may be an access network device. For example, the access network device may transmit broadcast messages in a broadcast area. For example, the third network device is an access network device that broadcasts alarm information to the broadcast area.

[0192] In some embodiments, the second network device directly sends the first information to the third network device.

[0193] In some embodiments, the second network device determines whether to send the first information to the third network device based on whether the access type of the broadcast area includes NTN access. For example, if it is found that the access type used in the broadcast area includes NTN access, the first information is sent to the third network device.

[0194] In some embodiments, the second network device determines whether the access type used in the broadcast area includes NTN access. If it is determined that the access type used in the broadcast area includes NTN access, the second network device sends first information to the third network device.

[0195] In some embodiments, the second network device may determine whether the access type of the broadcast area includes NTN access, which may include: determining whether the access type of the broadcast area includes NTN access based on a second configuration.

[0196] In some embodiments, the second configuration may be a local configuration of the second network device. For example, the second configuration may include, but is not limited to, carrier configuration and / or policies provided by higher-level devices for the second network.

[0197] Correspondingly, the third network device receives the first information sent by the second network device.

[0198] In some embodiments, if the access type of the broadcast area does not include NTN access, the second network device may not send the first information to the third network device.

[0199] In some embodiments, regardless of whether the access type of the broadcast area is NTN access or TN access, the second network device sends the first information to the third network device.

[0200] The third network device is determined before the second network device sends the first information to the third network device.

[0201] In some embodiments, the second network device determines the third network device based on the first information. For example, if the second network device obtains the geographical location information of each candidate device for the third network device, it can determine the third network device based on the first information and the geographical location information of the candidate devices.

[0202] In some embodiments, the second network device determines the second information based on the first information. In some embodiments, the second network device determines the third network device based on the second information. In some embodiments, the second information is used to indicate cells and / or tracking areas associated with (including) the broadcast area. Exemplarily, the third network device is an access network device for a cell included in the broadcast area, and / or, the third network device is an access network device within a tracking area included in the broadcast area.

[0203] In some embodiments, the second network device determines the third network device based on the first information and / or the second information.

[0204] In some embodiments, the step of determining the third network device is optional. For example, the second network device may default to any network device connected to it that is capable of receiving the first information as the third network device.

[0205] In some embodiments, the second network device sends a write-replacement request to the third network device, the write-replacement request including first information. In some embodiments, after receiving the first information, the third network device sends a second response to the second network device. If the first information is carried in the write-replacement request, the second response may be a write-replacement response. This write-replacement response can be used to indicate that the third network device has successfully received the first information. In some embodiments, the second response can also be used to instruct the third network device to begin distributing the first information.

[0206] In some embodiments, if the third network device returns a second response to the second network device after receiving the first information, the second network device may receive the second response within a second time period after sending the first information. If the second response is not received within the second time period, it can be considered that the first information transmission failed, and the second network device may retransmit the first information or reselect the third network device to receive the first information.

[0207] In some embodiments, the first information received by the third network device may be provided by the first network device and forwarded by the second network device.

[0208] In some embodiments, the second network device receives first information from the first network device and sends the first information to the third network device.

[0209] In some embodiments, the second network device receives first information and third information from the first network device and sends the first information and third information to the third network device.

[0210] S2103: The third network device sends a broadcast message to the terminal.

[0211] In some embodiments, the third-party network device broadcasts alarm information to the terminal. This alarm information is a type of broadcast message.

[0212] In some embodiments, the broadcast message includes first information. For example, alarm information includes first information. This first information can be used by the terminal receiving the broadcast message to determine whether to process or display the broadcast message. For instance, if the terminal is located within the broadcast area indicated by the first information, the terminal displays the broadcast message. Alternatively, if the terminal is located outside the broadcast area indicated by the first information, the terminal does not display the broadcast message.

[0213] In some embodiments, the third network device sends a broadcast message in the broadcast area based on the first information. For example, the third network device broadcasts alarm information in the broadcast area.

[0214] In some embodiments, the third network device sends a broadcast message based on the first information. The broadcast message includes tagging information. For example, the broadcast area may not encompass the entire area of ​​a cell belonging to the third network device. In this case, the third network device sends a broadcast message within that cell, carrying the tagging information in the broadcast message. The tagging information can be set based on the first information, or the tagging information itself can be the first information. For example, the tagging information can be used to mark a portion of the cell that belongs to the broadcast area. After receiving the alarm information and the tagging information, the terminal can determine whether to discard or display the alarm information based on whether it belongs to the broadcast area.

[0215] For example, NTN base station A is a base station within a broadcast area. A portion of cell A within NTN base station A belongs to the broadcast area, but the broadcast area is not limited to a portion of cell A and also includes other cells such as cell B. This marking information can mark only the portion of cell A within the broadcast area, rather than carrying the entire first information, which can reduce message overhead and / or the decoding difficulty for the terminal to some extent.

[0216] In some embodiments, the third network device sends a broadcast message within the broadcast area based on the first information and the third information. For example, if the third network device receives the first information and the third information from the second network device, the third network device will determine whether its corresponding coverage area is within the broadcast area based on the first information and the third information. If it is within the broadcast area, it will send a broadcast message within the corresponding area.

[0217] In some embodiments, a third network device receives first information and third information from a second network device and sends a broadcast message to a terminal, the broadcast message including the first information and the third information.

[0218] In some embodiments, the third network device has a locally stored third configuration. Upon receiving the first information or after receiving both the first and third information, the third network device determines, in conjunction with its third configuration, whether it belongs to an access network device within a broadcast area. If the third network device belongs to an access network device within a broadcast area, it sends a broadcast message; otherwise, the third configuration can be ignored. In this case, step S2103 is equivalent to being an optional step.

[0219] When a third network device sends a broadcast message, the terminal receives the broadcast message. In some embodiments, the broadcast information received by the terminal includes first information; or, the broadcast message received by the terminal includes both first information and third information. In some embodiments, the broadcast message received by the terminal may not include the first information; or, the broadcast message received by the terminal may not include both the first information and the third information.

[0220] In some embodiments, the third network device has a locally stored third configuration. After receiving the first information or both the first and third information, it determines, in conjunction with the third configuration, whether the third network device itself belongs to an access network device within the broadcast area. If the third network device belongs to an access network device within the broadcast area, it broadcasts an alarm message; otherwise, it can ignore the first information or ignore both the first and third information. In this case, step S2103 is equivalent to an optional step.

[0221] By way of example, the information processing methods provided in this disclosure are not limited to, but include, at least one of the following:

[0222] Method 1: The first network device sends the first information to the third network device.

[0223] Method 2: The first network device determines whether the broadcast area access type includes NTN access. If the broadcast area access type includes NTN access, the first network device sends first information to the second network device. After receiving the first information, the second network device sends first information to the third network device.

[0224] Method 3: The first network sends the first information to the second network device. After receiving the first information, the second network device determines whether the access type of the broadcast area includes NTN access. If the broadcast area includes NTN access, it sends the first information to the third network device.

[0225] Of course, the above are just examples, and the specific implementation is not limited to the examples above.

[0226] In some embodiments, the names of information, etc., are not limited to those described in the embodiments. Terms such as "information," "message," "signal," "signaling," "report," "configuration," "indication," "instruction," "command," "channel," "parameter," "domain," "field," "symbol," "symbol," "codebook," "codeword," "codepoint," "bit," "data," "program," and "chip" can be used interchangeably. For example, "information" in "first information" can also be understood as "message," "parameter," or "configuration," etc.

[0227] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0228] In some embodiments, if an arrow in the interaction diagram representing the transmission of information, signaling, etc., from one subject to another passes through other subjects, it can be interpreted as the transmission from one subject to another via other subjects, or as the transmission from one subject to another without passing through other subjects. For example, if S2101 represents the first network device sending first information to the second network device, it means the second network device receives the first information from the first network device. As another example, if S2102 represents the second network device sending first information to the third network device, it means the third network device receives the first information from the second network device.

[0229] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2103. For example, any one of steps S2101, S2102, and S2103 may be implemented as an independent embodiment.

[0230] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0231] Figure 2B is another interactive schematic diagram of an information processing method according to an embodiment of the present disclosure. This disclosure relates to an information processing method that can be executed by the communication system shown in Figure 1A. As shown in Figure 2B, the method includes:

[0232] S2201: The first network device determines whether the access type of the broadcast area includes NTN access.

[0233] In some embodiments, the first network device determines whether the access type of the broadcast area includes NTN access, as shown in the relevant part of S2101 in FIG2A.

[0234] S2202: The access type of the broadcast area includes NTN access, and the first network device sends the first information to the second network device.

[0235] In some embodiments, the access type of the broadcast area includes NTN access, and the first network device sends first information and third information to the second network device.

[0272] In some embodiments, the network device may be one or more of a core network device and an access network device. For example, the network device may include one or more of a CBC, CBCF, MME, AMF, eNB, and gNB.

[0275] To further illustrate the technical solutions provided in the embodiments of this disclosure, one or more embodiments are provided below, as detailed below.

[0276] Example 1:

[0277] (1) The CBC and / or CBCF determine first information based on the area information provided by the CBE. The first information is geographic information of an alarm area. This geographic information is different from information that uses cell identifiers and / or TAI to represent the range of alarm information broadcast. For example, the geographic information can be a geometric figure enclosed by coordinate information, or a geographic range corresponding to a circle represented by the coordinates of the center point and the radius. The geographic range may be smaller or larger than the area represented by cell or TA.

[0278] (2) Optionally, when determining the first information, the CBC and / or CBCF may also combine network access information. The network access information indicates the network access type (e.g., the access type may be NTN access or TN access). This network access information may be obtained from the MME and / or AMF.

[0279] (3) The first information can be used to identify the broadcast range of the alarm information alone. Alternatively, the first information, the cell identifier, and / or the TAI can be combined to identify the broadcast range of the alarm information.

[0280] (4) Based on the first information, the CBC and / or CBCF selects MME and / or AMF.

[0281] (5) The CBC and / or CBCF send the first information to the MME and / or AMF, and the first information is used by the MME and / or AMF to select the eNB and / or gNB.

[0282] (6) According to (5), the MME and / or AMF send the first information to the eNB and / or gNB.

[0283] (7) According to (6), when the MME and / or AMF learns that NTN access is used, it sends the first information to the eNB and / or gNB.

[0284] (8) The CBC and / or CBCF send the first information to the eNB and / or gNB, the first information being used by the eNB and / or gNB to send alarm information within the broadcast range indicated by the first information.

[0285] (9) The first information is sent by CBC and / or CBCF to MME and / or AMF, and further sent by MME and / or AMF to eNB and / or gNB.

[0286] (10) According to (8), when the CBC and / or CBCF learns that the alarm area uses NTN access, it sends the first information to the eNB and / or gNB.

[0287] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0288] Example 2:

[0289] As shown in Figure 3, this embodiment of the present disclosure provides an information processing method, including:

[0290] 0. Perform network registration and security (e.g., mutual authentication) processes.

[0291] 1. CBE (such as information sources like PSAP or regulatory agencies) sends emergency information to CBC (such as "warning type", "alarm information", "affected area", "time period").

[0292] 2. Using the "Affected Areas" information, CBC determines which MMEs need to be contacted and identifies a list of alarm areas. CBC sends a Write-Replace Warning Request message, which includes the alarm information to be broadcast and distribution attributes (message identifier, sequence number, TAI and / or geographic alarm area, list of alarm areas, OMC ID, CWM indicator, Write-Replace-Warning-Indication, eNB ID, alarm area coordinates) to the MME.

[0293] The MME selects the eNB based on the TAI list information and sends a Write-Replace Warning Request message.

[0294] The Warning Area List consists of a list of cell IDs, a list of tracking area IDs (TAIs), or one or more emergency area IDs (EAIs) or geographic warning areas (i.e., the first information). The Warning Area List is used only by the eNB. The eNB is configured with TAIs and cell IDs serving the emergency area IDs or the geographic warning areas. The eNB checks the cell IDs in the configuration that match the Warning Area List and distributes the alarm message to the cell corresponding to that cell ID.

[0295] The process of sending the geographical alarm area (i.e., the first information) can be implemented in the following ways:

[0296] Method 1: The CBC sends the geographic alarm area to the MME. The MME forwards it to the eNB. In the above implementation, the geographic alarm area can be included in the alarm area list, sent by the CBC to the MME, and then further sent to the eNB.

[0297] Method 2: The CBC sends the geographic alarm area to the MME. The MME detects that NTN access is used in the area and then sends the geographic alarm area to the eNB.

[0298] Method 3: When the CBC detects NTN access within the geographic alarm area, it sends the geographic alarm area to the MME, which in turn sends it to the eNB. In the above implementation, the geographic alarm area can be included in an alarm area list sent by the CBC to the MME and then to the eNB.

[0299] For the process of how CBC or MME detects NTN access, the above methods can be used as follows:

[0300] If the MME and / or CBC need to know about NTN access, the CBC can determine whether NTN access is used within the geographic alarm area based on subscriptions / notifications. For example, the CBC can subscribe to relevant access types or RAT types. If the access type or RAT type is associated with NTN access, the MME will notify the CBC of the NTN access. Alternatively, depending on the configuration, the CBC and / or MME may know whether a cell or TAI within the geographic alarm area is associated with an NTN-accessed cell or TAI. The geographic alarm area is determined by the CBC and refers to the area where alarm information needs to be broadcast.

[0301] 3. The MME sends a Write-Replace Warning Confirm message to the CBC, instructing the MME to begin distributing alarm information to the eNB. If the CBC does not receive this message within a specific time period, the CBC can attempt to send the alarm information through other MMEs in the MME resource pool. An MME resource pool can include one or more MMEs, which can be configured to connect to eNBs in the same geographic region.

[0302] 4. After receiving a Write-Replace Warning Confirm message from the MME, the CBC can confirm to the CBE that it has started distributing alarm information.

[0303] 5. The MME forwards the Write-Replace Warning request message to the eNB. The MME should use the TAI list and / or the geographic warning area information to determine the eNB associated with the broadcast area. If the request message does not contain a TAI and / or the geographic warning area information, and an eNB ID is not received from the CBC, the warning message will be forwarded to all eNBs connected to the MME. If an eNB ID is received from the CBC, the MME should forward the warning message to the eNB indicated by the eNB ID.

[0304] 6. When using S1-flex, the eNB may receive the same message from multiple MMEs. The eNB detects message duplication by checking the message identifier and sequence number fields in the alarm message. If message duplication is detected, the cell only broadcasts the first received message. The eNB should use the Warning Area List to determine the cells in which to broadcast the message. The eNB returns a distributed alarm message response to the MME. For example, S1-flex is an interface. This Warning Area List contains the aforementioned geographical alarm area information.

[0305] 7. If the terminal is configured to receive alarm information, and the terminal is configured to receive alarms on this PLMN, the terminal will process them as follows:

[0306] The terminal can immediately alert the user using a "warning type" value ("earthquake", "tsunami", or "earthquake and tsunami"). When the "warning type" is 'test', the terminal discards the main notification.

[0307] 8. If a Write-Replace-Warning-Indication is present in the write replacement warning request, the MME should send the broadcast scheduling area list information to the CBC. The broadcast scheduling area list should include the list of broadcast completed areas received from the eNB. The MME may aggregate the list of broadcast completed areas it receives from the eNB.

[0308] 9. In the Write-Replace Warning Response message returned from the eNB, the MME determines whether the transmission was successful or failed and creates a log.

[0309] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0310] Example 3:

[0311] As shown in Figure 4, this embodiment of the present disclosure provides an information processing method, including:

[0312] 0. Perform network registration and security (e.g., mutual authentication) processes.

[0313] 1. The CBE (e.g., information source such as PSAP or regulatory agencies) sends an emergency broadcast request to the CBCF. This emergency broadcast request may include one or more of the following: "Warning Type", "Alarm Message", "Affected Area", and "Time Period". The CBCF should verify this request.

[0314] 2. Using the "Affected Area" information, the CBCF determines which AMFs need to be contacted and identifies the alarm area list. The CBCF sends a Write-Replace Warning Request (NG-RAN) message to the AMF, which includes the alarm information to be broadcast and distribution attributes (message identifier, sequence number, NG-RANTAI and / or geographical alarm area, alarm area list NG-RAN, OMCID, CWM indicator, send write-replace-warning-indicator, RAN node, node ID, alarm area coordinates). For example, this Write-Replace Warning Request (NG-RAN) message can be a UE-independent N2 message transfer (NonUeN2MessageTransfer).

[0315] AMF selects an NG-RAN node based on NG-RANTAI and sends a Write-Replace Warning Request message.

[0316] The process of sending the geographical alarm area (i.e., the first information) can be implemented in the following ways:

[0317] Method 1: The CBCF sends the geographic alarm region to the AMF. The AMF forwards it to the NG-RAN node. In the above implementation, the geographic alarm region can be included in the alarm region list, sent by the CBCF to the AMF, and then further sent to the NG-RAN node.

[0318] Method 2: The CBCF sends the geographical alarm area to the AMF. The AMF detects that NTN access is used in the area, and the AMF sends the geographical alarm area to the NG-RAN node.

[0319] Method 3: When the CBCF detects NTN access within the geographical alarm area, it sends the geographical alarm area to the AMF, and then further to the NG-RAN node. In the above implementation, the geographical alarm area can be included in the alarm area list and sent by the CBCF to the AMF and then further to the NG-RAN node.

[0320] Regarding the process of how the CBCF or AMF detects NTN access, the following method can be used: If the CBCF and / or AMF need to know about NTN access, the CBCF can determine whether NTN access is used within the geographic alarm area based on subscriptions / notifications. For example, the CBCF can subscribe to relevant access types or RAT types. If the access type or RAT type is related to NTN access, the AMF will notify the CBCF of the NTN access. Alternatively, depending on the configuration, the CBCF and / or AMF can determine whether the cells or TAIs within the geographic alarm area are connected to cells or TAIs under NTN access. The geographic alarm area is determined by the CBCF and refers to the area where alarm information needs to be broadcast.

[0321] 3. The AMF sends a Write-Replace Warning Confirm NG-RAN message, instructing the CBCFAMF to begin distributing alarm information to NG-RAN nodes.

[0322] If the CBCF does not receive this message within the appropriate time period, the CBCF may attempt to pass the alarm information through another AMF in the same AMF area.

[0323] 4. After receiving the write-replacement acknowledgment NG-RAN message from the AMF, the CBCF can confirm to the CBE that it has started distributing alarm information.

[0324] 5. The AMF forwards the Write-Replace Warning Message Request (NG-RAN) message to the NG-RAN nodes. The AMF should use the NG-RAN TAI and / or the list of geographic alarm areas to determine the NG-RAN nodes in the delivery area. If the NG-RAN TAI and / or the list of geographic alarm areas are not included, and the Global RAN Node ID is not received from the CBCF, the message will be forwarded to all NG-RAN nodes connected to the AMF, depending on the RAT selector NG-RAN. If the Global RAN Node ID has been received from the CBCF, the AMF should only forward the message to the NG-RAN node indicated by the Global RAN Node ID Information Element (IE).

[0325] 6. When a CBCF sends alarm information to multiple AMFs for the same alarm area, an NG-RAN node may receive the same message from multiple AMFs. NG-RAN nodes detect duplicate messages by checking the message identifier and sequence number fields in the alarm message. If any redundant messages are detected, the cell will only broadcast the first message received. NG-RAN nodes should use [this feature / method / approach].

[0326] 7. If the terminal is configured to receive alarm information and is configured to accept warnings from this PLMN, the terminal will proceed as follows:

[0327] The terminal can immediately alert the user using a "warning type" value ("earthquake", "tsunami", or "earthquake and tsunami"). When the "warning type" is 'test', the terminal discards the main notification.

[0328] 8. If the Write Replacement Warning Request NGRAN contains a Send Warning-Message-Indication parameter, and this parameter is configured in the AMF according to operator policy, the AMF should forward the list of broadcast scheduled areas in the Write Replacement Warning Request NGRAN to the CBCF. The list of broadcast scheduled areas should include the list of broadcast completed areas received by the AMF from the NGRAN nodes. The AMF may aggregate the list of broadcast completed areas it receives from the NGRAN nodes.

[0329] 9. Based on the Write-Replace Warning Response message returned by the NG-RAN node, the AMF determines whether the transmission was successful or failed and creates a log.

[0330] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0331] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0332] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0333] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
