It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning unless explicitly defined in this disclosure.

[0031] The disclosed embodiment provides a disaster warning method, which can be applied to any form of terminal that can be connected to a non-terrestrial communication network.

[0032] Figure 1 The figure shows a flow chart of a method for performing disaster warning on the terminal side, which mainly includes:

[0033] Step 101: monitor disaster warning messages broadcast by non-terrestrial communication networks, wherein the disaster warning messages include geographical scope information of the disaster warnings.

[0034] In an exemplary embodiment, a geographical range field is included in the disaster warning message, and the geographical range field stores geographical range information.

[0035] Step 102: parse the monitored disaster warning message to obtain the geographical scope information of the disaster warning.

[0036] In some embodiments, the geographic range information includes indication information of at least one of the following geographic range types: indication information of a designated beam cell; indication information of a designated satellite cell; indication information of a designated satellite tracking area; indication information of a designated PLMN (Public Land Mobile Network); indication information of the entire network. It should be noted that this is only an example, and the indication information of the geographic range type may also be other parameters that can clarify the geographic range, and the protection scope of the present disclosure is not limited to this.

[0037] In an exemplary embodiment, the geographic range field includes two parameters, namely, the type of geographic range and the value of geographic range, and the two parameters are combined as indication information of the type of geographic range. Table 1 shows an example of the type of geographic range and its corresponding meaning.

[0038] Table 1 Types of geographical scope and their corresponding meanings

[0039] Type of geographic range meaning 1 Designated beam cell 2 Designated satellite cell 3 Specify satellite tracking area 4 Specify PLMN 5 Whole network

[0040] For example, assume that the content of the geographic scope field in the disaster warning message monitored by the terminal is as follows: indicating that the warning area is beam cell 1 of the satellite network, where the loc_type parameter is used to identify the "type of geographic scope", and the value is 1, indicating that the type of geographic scope is "specified beam cell"; the beam parameter is used to identify the "beam cell ID", that is, the value of the geographic scope, and the value is 1, indicating that the beam cell with the designated beam ID 1 is used as the warning area.

[0041] Step 103, based on the geographical scope information of the disaster warning and the current geographical location information of the terminal, determine whether the terminal is currently within the geographical scope of the disaster warning, if so, broadcast the disaster warning message, if not, do not broadcast the disaster warning message.

[0042] In some embodiments, the disaster warning message also includes a disaster warning unique identifier;

[0043] The method for the terminal to perform disaster warning also includes: parsing the monitored disaster warning message to obtain the unique identifier; if there is already a disaster warning message with the same unique identifier in the historically monitored disaster warning messages, discarding the latest monitored disaster warning message; if there is no disaster warning message with the same unique identifier in the historically monitored disaster warning messages, executing the step of determining whether the terminal is currently within the geographical scope of the disaster warning.

[0044] In some embodiments, the unique identifier of the disaster warning includes at least one of the following: a serial number, which is used to identify the order in which the disaster warning is issued; and a timestamp, which is used to indicate the time when the disaster warning is issued.

[0045] In an exemplary embodiment, a disaster warning message includes a sequence number field, which is used to carry the sequence number of the disaster warning message. The sequence number is used to distinguish new disaster warning messages from disaster warning messages that have been received. When the sequence number of the disaster warning message is different from the sequence number of the disaster warning message that has been received, it is determined to be a new disaster warning message. When the sequence number of the disaster warning message is the same as the sequence number of the disaster warning message that has been received, it is determined not to be a new disaster warning message. Each time a new disaster warning message is broadcast in a non-terrestrial communication network, the sequence number in the sequence number field is updated, for example, by incrementing a set value (for example, by 1) based on the original sequence number.

[0046] In some embodiments, the disaster warning message also includes issuing agency information; the issuing agency information identifies the issuing agency of the disaster warning message and is used to identify authentic disaster warning messages.

[0047] The method for a terminal to conduct disaster warning also includes: parsing the monitored disaster warning message to obtain the issuing agency information; when it is determined according to the issuing agency information that the issuing agency of the disaster warning message is not a legal agency, discarding the disaster warning message corresponding to the issuing agency information; when it is determined according to the issuing agency information that the issuing agency of the disaster warning message is a legal agency, executing the step of determining whether the terminal is currently within the geographical scope of the disaster warning.

[0048] In an exemplary embodiment, the disaster warning message includes an issuing agency field, in which issuing agency information is stored.

[0049] In some embodiments, the disaster warning message also includes the disaster type;

[0050] The method for the terminal to perform disaster warning also includes: parsing the monitored disaster warning message to obtain the disaster type; and broadcasting the disaster type.

[0051] In an exemplary embodiment, a disaster warning message includes a disaster type field, in which the disaster type is stored to identify the type of natural disaster. Disaster types include but are not limited to: earthquakes, typhoons, tornadoes, tsunamis, floods, mudslides, sandstorms, volcanic eruptions, etc.

[0052] In some embodiments, the disaster warning message also includes a warning level, which is used to indicate the severity of the disaster warning;

[0053] The method for the terminal to perform disaster warning also includes: parsing the monitored disaster warning message to obtain the warning level; and broadcasting the warning level.

[0054] In an exemplary embodiment, a warning level field is included in the disaster warning message, and the warning level is stored in the warning level field.

[0055] In some embodiments, the disaster warning message also includes longitude and latitude information of the disaster core area;

[0056] The method for the terminal to conduct disaster warning also includes: parsing the monitored disaster warning message to obtain the longitude and latitude information of the disaster core area; determining the distance information between the terminal and the disaster core area based on the longitude and latitude information of the terminal's current location and the longitude and latitude information of the disaster core area; and broadcasting the distance information.

[0057] In an exemplary embodiment, a disaster warning message includes a disaster core area field, and the disaster core area field stores the latitude and longitude information of the disaster core area.

[0058] In some embodiments, the disaster warning message also includes the time when the disaster occurs.

[0059] In some embodiments, the terminal broadcasts disaster warning messages in a variety of ways, such as broadcasting disaster warning messages to users through at least one of voice broadcast, text broadcast, flashing lights, vibration, etc. The terminal broadcasts disaster warning messages, which may cause the user interface to change to remind the user. The terminal broadcasts disaster warning messages including at least one of the following: the disaster type, warning level, timestamp (i.e., release time), longitude and latitude information of the disaster core area, and the time when the disaster occurred.

[0060] In the disclosed embodiment, when a disaster warning message is broadcasted through a non-terrestrial communication network, the geographical scope information of the disaster warning is carried in the disaster warning message. The terminal parses the monitored disaster warning message to obtain the geographical scope information of the disaster warning. According to the geographical scope information of the disaster warning and the geographical location information of the terminal, it is determined whether the terminal is currently within the geographical scope of the disaster warning. If so, the disaster warning message is broadcasted; if not, the disaster warning message is not broadcasted. Thus, it is possible to broadcast disaster warning messages using non-terrestrial communication networks, and quickly and accurately carry out disaster warnings using the geographical scope information carried in the disaster warning messages, and to carry out disaster warnings in areas not covered by terrestrial communication networks.

[0061] Based on the same concept, a disaster warning method is also provided in an embodiment of the present disclosure. The method can be applied to a non-terrestrial communication network that can establish a communication connection with a terminal.

[0062] Figure 2 The figure shows a flow chart of a method for disaster early warning using a non-terrestrial communication network. The method mainly includes:

[0063] Step 201: Generate a disaster warning message, wherein the disaster warning message includes geographical scope information of the disaster warning.

[0064] In some embodiments, the disaster warning message also includes a unique disaster warning identifier.

[0065] In some embodiments, the disaster warning unique identifier includes at least one of the following:

[0066] A serial number, which is used to identify the order in which the disaster warning is issued;

[0067] A timestamp is used to indicate the time when the disaster warning is issued.

[0068] In some embodiments, the disaster warning message further includes at least one of the following:

[0069] Release information of the organization;

[0070] Type of disaster;

[0071] Warning level, which indicates the severity of the disaster warning;

[0072] The latitude and longitude information of the disaster core area;

[0073] Time of disaster occurrence.

[0074] In some embodiments, the geographic range information includes indication information of at least one of the following geographic range types:

[0075] Indication information of the designated beam cell, such as the beam cell identifier;

[0076] Indication information of a designated satellite cell, such as a satellite cell identifier;

[0077] Indicative information for specifying a satellite tracking area, such as a satellite tracking area identifier;

[0078] Indication information for specifying PLMN;

[0079] Instructions for the entire network.

[0080] In some embodiments, generating a disaster warning message includes: obtaining disaster information provided by a legitimate professional organization, the disaster information including at least one of the disaster type, disaster level, longitude and latitude information of the disaster core area, and the time of occurrence of the disaster warning, and generating a disaster warning message based on the disaster information. Specifically, based on the disaster type, disaster level, and longitude and latitude information of the disaster core area, a calculation formula corresponding to the disaster type and disaster level is used to calculate the geographical scope information of the disaster warning corresponding to the disaster core area. Among them, the mapping relationship between the calculation formula, disaster type, and disaster level is pre-configured in the non-terrestrial communication network. Of course, the geographical scope information of the disaster warning can also be provided by a professional organization.

[0081] In some embodiments, generating a disaster warning message includes: obtaining geographical scope information of the disaster warning, as well as one or more of the disaster type, disaster level, longitude and latitude information of the disaster core area, and the time of occurrence of the disaster warning, and generating the disaster warning message according to the set format of the disaster warning message.

[0082] Step 202: broadcast the disaster warning message.

[0083] Specifically, the non-terrestrial communication network broadcasts the disaster warning message through a broadcast channel.

[0084] In the disclosed embodiment, when a disaster warning message is broadcast through a non-terrestrial communication network, the geographical scope information of the disaster warning is carried in the disaster warning message, so that the terminal can judge whether the warning information needs to be broadcast based on the geographical scope information in the disaster warning message, so that the disaster warning message can be broadcast by using the non-terrestrial communication network, and the disaster warning can be quickly and accurately carried out through the geographical scope information carried in the disaster warning message, and the disaster warning can also be carried out in areas without ground communication network coverage. This method is simple and practical, and can broadcast the disaster warning message to the terminal in a short time, which wins precious time for disaster prevention and mitigation. In addition, the method of broadcasting through a non-terrestrial communication network does not require the establishment of a special warning distribution system, and the cost is low and easy to promote. In addition, the method of broadcasting disaster warning messages through a non-terrestrial communication network can make full use of the one-way public control channel, avoiding the problem that the capacity limitation may cause congestion in the case of using a two-way dedicated channel, so that the user cannot receive the disaster warning message for a long time, while the one-way public control channel does not have this problem. Broadcast channel signaling generally broadcasts multiple messages, which improves the transmission success rate compared to the short message transmission form.

[0085] In the above embodiments, the non-terrestrial communication network may be a satellite network. The beam coverage of a satellite in the satellite network may reach thousands of kilometers. The disaster warning method provided in the embodiments of the present invention can avoid the problem that, when disaster warning messages are transmitted through a satellite network, a large number of terminals within the satellite coverage area receive unexpected disaster warning messages, thereby affecting the normal life and work of the public, thereby achieving rapid and accurate disaster warnings.

[0086] In the exemplary embodiment, taking earthquake early warning as an example, when an earthquake occurs, the earthquake monitoring station near the epicenter quickly determines the time and location of the earthquake, and then the legally authorized professional organization issues an earthquake disaster early warning through cellular operators and satellite communication operators. The satellite system determines the scope of the disaster according to the type of natural disaster (such as direct earthquake disasters mainly occur within tens or hundreds of kilometers around the epicenter), and thus sets the corresponding geographical range information in the disaster early warning information.

[0087] In the exemplary embodiment, taking a satellite network as an example, Figure 3 The schematic diagram of the satellite-based disaster warning method flow chart shows the disaster warning process as follows:

[0088] Step 301, the terminal accesses the satellite network;

[0089] Step 302, the terminal determines whether it monitors the disaster warning message broadcast by the satellite network through the broadcast channel; if so, continue to step 303, otherwise, return to step 302;

[0090] Step 303, the terminal parses the contents of fields such as serial number, timestamp, disaster type, and geographic scope in the disaster warning message;

[0091] Step 304, the terminal determines whether it is a repeated disaster warning message according to the parsed information; if not, continue to step 305, if so, execute step 307;

[0092] Step 305: the terminal determines whether it is within the range of the designated warning area included in the geographic range field according to the parsed information. The designated warning area may be one of the multiple geographic range types carried in the geographic range field. If yes, proceed to step 306; otherwise, proceed to step 307.

[0093] Step 306, the terminal broadcasts the disaster warning message to the user;

[0094] Step 307, end the process.

[0095] In the exemplary embodiment, it is assumed that a satellite cell (i.e., PCI (Physical Cell Identifier, i.e., physical cell identifier or physical cell ID) includes multiple beam cells (Satellite beam), Figure 4 The figure shows a schematic diagram of multiple beam cells contained in a satellite cell.

[0096] The geographic range field in the disaster warning message may include one or more parameters of the same geographic range type. For example, the geographic range field includes beam cell ID1 and beam cell ID2.

[0097] The geographic scope field in the disaster warning message may also be a parameter containing one or more different geographic scope types. Figure 5 The figure shows two types of geographical ranges: tracking area and beam cell. The geographical range field of the disaster warning message can be set to: beam cell ID1 and tracking area identifier 1 (ie, TAI1), indicating that the warning area is the geographical range covered by TAI1 and beam cell ID1. TAI = PLMN + TAC (Tracking Area Code). Figure 5 The area surrounded by the irregular boundary is the tracking area. There are four tracking areas, namely TA1, TA2, TA3 and TA4; the elliptical area is the coverage area of ​​the satellite's beam cell. The three satellites (satellite A, satellite B and satellite C) each correspond to a beam cell.

[0098] The step division of the above various methods is only for clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the protection scope of this disclosure. Adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the protection scope of this disclosure.

[0102] Processing module 603 is used to determine whether the terminal is currently within the geographical scope of the disaster warning based on the geographical scope information of the disaster warning and the geographical location information of the terminal. If so, broadcast the disaster warning message; if not, do not broadcast the disaster warning message.

[0103] In some embodiments, the processing module 603 includes a detection submodule 6031, a judgment submodule 6032, and a broadcast submodule 6033;

[0104] The detection submodule 6031 is used to detect the geographical location information of the terminal itself, and determine whether the terminal is within the geographical range of the disaster warning according to the geographical range information of the disaster warning and the geographical location information of the terminal at the current location;

[0105] The judgment submodule 6032 is used to judge whether the monitored disaster warning message is a repeated message;

[0106] The broadcast submodule 6033 is used to broadcast the disaster warning message to the user when the detection submodule 6031 determines that the terminal is within the geographical range of the disaster warning and the judgment submodule 6032 determines that the message is not a duplicate received message.

[0107] In some embodiments, the parsing module 602 is used to parse the disaster warning message to obtain the content of each field of the disaster warning message, such as obtaining the content of the serial number, timestamp, issuing agency, disaster type, warning level, geographical scope and other fields in the disaster warning message.

[0108] In some embodiments, the judgment submodule 6031 is also used to read the sequence number and timestamp fields in the disaster warning message, and compare the one or more fields with the corresponding fields in the previously received disaster warning message. If the comparison result is the same, it is judged to be a duplicate message, and the disaster warning message is discarded.
