Description

Rescue support device and rescue support method

[0001] The present invention relates to a technique for assisting rescue of disaster victims.

[0002] 3GPP (registered trademark) (3rd Generation Partnership Project) has introduced a wireless communication system called 5G or NR (New Radio) (hereinafter, the wireless communication system will be referred to as "5G" or "NR") in order to achieve a larger system capacity, a higher data transmission speed, and a lower latency in wireless sections. 5G introduces various wireless technologies to meet the requirement of achieving a throughput of 10 Gbps or more while reducing the latency in wireless sections to 1 ms or less (for example, Non-Patent Document 1). Furthermore, 6G, a future communication system, is also being studied.

[0003] Using networks such as 5G, devices can perform high-speed mobile communications. However, in the event of a disaster such as a large-scale earthquake, devices may become unusable due to water damage or physical damage, or even if the device is usable, users may be unable to operate it due to the damage.

[0004] 3GPP TS 38.300 V18.0.0 (2023-12)

[0005] In the above situation, the victim will not be able to request rescue using their own terminal.

[0006] The present invention has been made in view of the above points, and has an object to provide a technique for supporting the rescue of disaster victims when a disaster occurs.

[0007] According to the disclosed technology, a rescue support device is provided that includes: a receiving unit that receives first information obtained through a mobile network that communicates with a terminal and second information that indicates the disaster situation; and a control unit that detects the status of a user of the terminal based on the first information, and determines the need for rescue for the user based on the status of the user and the second information.

[0008] The disclosed technology provides a technology for assisting in rescuing disaster victims when a disaster occurs.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the embodiment described below is an example, and the embodiment to which the present invention is applied is not limited to the following embodiment.

[0011] In the operation of the wireless communication system according to the embodiment of the present invention, existing technologies are used as appropriate. However, the existing technologies include, but are not limited to, the existing LTE or the existing NR.

[0012] In the following, first, an example of the configuration of a mobile network used in this embodiment will be described, and then the configuration and operation relating to relief support in the event of a disaster will be described.

[0013] Fig. 1 is a diagram illustrating an example of a communication system corresponding to a mobile network. As shown in Fig. 1, this communication system is composed of a UE and multiple network nodes. Hereinafter, it is assumed that one network node corresponds to each function, but multiple functions may be realized by one network node, or multiple network nodes may realize one function. Furthermore, the "connection" described below may be a logical connection or a physical connection.

[0014] A Radio Access Network (RAN) is a network node having a radio access function, which may include a base station, and is connected to a UE, an Access and Mobility Management Function (AMF), and a User plane function (UPF). The AMF is a network node having functions such as terminating the RAN interface, terminating the Non-Access Stratum (NAS), registration management, connection management, reachability management, and mobility management. The UPF is a network node having functions such as a Protocol Data Unit (PDU) session point to the outside that interconnects with a Data Network (DN), packet routing and forwarding, and user plane Quality of Service (QoS) handling. The UPF and the DN constitute a network slice.

[0015] The AMF is connected to the UE, RAN, SMF (Session Management function), NSSF (Network Slice Selection Function), NEF (Network Exposure Function), NRF (Network Repository Function), UDM (Unified Data Management), AUSF (Authentication Server Function), PCF (Policy Control Function), and AF (Application Function). The AMF, SMF, NSSF, NEF, NRF, UDM, AUSF, PCF, and AF are network nodes interconnected via interfaces based on their respective services: Namf, Nsmf, Nnssf, Nnef, Nnrf, Nudm, Nausf, Npcf, and Naf.

[0016] The SMF is a network node that has functions such as session management, UE IP (Internet Protocol) address allocation and management, DHCP (Dynamic Host Configuration Protocol) function, ARP (Address Resolution Protocol) proxy, and roaming function. The NEF is a network node that has the function of notifying other NFs (Network Functions) of capabilities and events. The NSSF is a network node that has functions such as selecting a network slice to which a UE connects, determining the allowed NSSAI (Network Slice Selection Assistance Information), determining the NSSAI to be configured, and determining the AMF set to which the UE connects. The PCF is a network node that has the function of controlling network policies. The AF is a network node that has the function of controlling application servers. The NRF is a network node that has the function of discovering NF instances that provide services. The UDM is a network node that manages subscriber data and authentication data. The UDM is connected to a UDR (User Data Repository) that stores the data.

[0017] 2 is a diagram illustrating an example of a communication system in a roaming environment. As shown in FIG. 2, the network is made up of a UE and a plurality of network nodes.

[0018] The SEPP is a non-transparent proxy that filters control plane messages between PLMNs (Public Land Mobile Networks). The vSEPP shown in Figure 2 is a SEPP in a visited network, and the hSEPP is a SEPP in a home network.

[0019] As shown in Figure 2, a UE is in a roaming environment connected to a RAN and an AMF in a Visited PLMN (VPLMN). The VPLMN and a Home PLMN (HPLMN) are connected via a vSEPP and an hSEPP. The UE can communicate with a UDM in the HPLMN via the AMF in the VPLMN, for example.

[0020] (Digital Twin) As will be described later, in this embodiment, a mechanism of Digital Twin is used, and therefore an overview of Digital Twin will be described here.

[0021] Digital Twin is a technology that uses data collected from the real world to recreate on a computer the objects, people, and processes that exist in physical space.

[0022] By using Digital Twin, it is possible to obtain real-world data in real time, perform analysis and simulations such as future predictions in a virtual space, and then realize a system that feeds the results back into reality.

[0023] (Regarding Issues) The following describes issues with the technology according to the present embodiment. As described above, in the event of a disaster such as a large-scale earthquake, a terminal may become unusable due to submersion in water or physical damage, or even if the terminal is usable, the user may be unable to operate the terminal due to the damage.

[0024] In such a situation, the user of the affected device needs to request rescue from rescue organizations or family members, but cannot contact them because the device is unavailable. Conventional technology exists for estimating damage using earthquake damage estimation systems, but it is not capable of providing disaster support such as locating victims.

[0025] (System Configuration Example and Operation Overview) In order to solve the above problems, this embodiment uses a rescue support device 30. The rescue support device 30 may be called a Digital Twin system. The rescue support device 30 may be a network node in a 3GPP network as shown in FIG. 1 . Furthermore, the rescue support device 30 may be a device external to the 3GPP network. The rescue support device 30 may be a base station or a terminal.

[0026] Fig. 3 shows an example of the configuration of a system including a rescue support device 30. As shown in Fig. 3, a mobile network (NW) 40, a meteorological agency 50, and an information destination 60 are connected to the rescue support device 30. The information destination 60 is, for example, a public institution or the family of a person to be supported. A terminal 20 held by a user is connected to the mobile NW 40. The "meteorological agency 50" is, for example, a web server of the meteorological agency.

[0027] The mobile network 40 includes a wireless sensing function, which is a technology for detecting objects, estimating states, and the like, based on fluctuations in radio waves between a base station and a terminal.

[0028] The rescue support device 30 acquires information indicating the disaster situation from the Japan Meteorological Agency 50, or estimates the disaster situation based on the wireless sensing results of the mobile NW 40. Note that the source of the information indicating the disaster situation is not limited to the Japan Meteorological Agency 50, and the rescue support device 30 may acquire information from any source that can provide information indicating the disaster situation.

[0029] In addition, the rescue support device 30 acquires, from the mobile NW 40, location information of the terminal and wireless sensing results of physical activity of the terminal user.

[0030] The rescue support device 30 uses the information acquired as described above to recreate the user's location and the disaster situation on Digital Twin, analyzes the data, and provides data on disaster victims who are likely to need rescue to a reliable information provider 60 such as a public institution or the victim's family. This data can support rescue operations.

[0031] That is, the rescue support device 30 maps the estimated damage situation information based on information from the Japan Meteorological Agency 50 and the mobile network 40 and the user's location information on a map, analyzes it on Digital Twin, calculates the possibility that the victim needs to be rescued, and provides the analysis results to public institutions or the victim's family, etc.

[0032] As described above, by using Digital Twin, it is possible to determine the possibility of damage taking into account surrounding data and time-series data.

[0033] (Information Collection Method) In this embodiment, the rescue support device 30 detects the status of the terminal or the user of the terminal, and acquires the damage status. An example of the status detection method and an example of the damage status acquisition method will be described below.

[0034] <Regarding Status Detection Method> In this embodiment, the following method A and method B are used to detect the status of a terminal or a user.

[0035] Method A: The rescue support device 30 detects that the terminal is unusable. For example, it detects a situation in which the user cannot use the terminal due to submersion in water, etc. More specifically, the rescue support device 30 monitors the status of periodic location registration for the terminal or a control signal from the terminal, and determines that the terminal is unusable if there is no periodic location registration or if the control signal is no longer received.

[0036] Method B: The rescue support device 30 detects that the user of the terminal is immobilized. In this state, the terminal is capable of communication but the user cannot use the terminal. More specifically, the rescue support device 30 monitors the user's physical movement using the results of wireless sensing performed by the mobile NW 40.

[0037] The user's condition may be detected using a method other than Method A and Method B. For example, the mobile NW 40 or the rescue support device 30 may be equipped with a camera, and the rescue support device 30 may detect the user's condition from an image captured by the camera.

[0038] <Methods for Acquiring Disaster Status> In this embodiment, the following methods X and Y are used to acquire the disaster status (disaster information).

[0039] Method X: The rescue support device 30 acquires the damage situation from disaster information for each area obtained from the Japan Meteorological Agency or the like.

[0040] Method Y: The rescue support device 30 acquires the disaster situation from the results of wireless sensing by the mobile network 40.

[0041] The damage situation may be acquired using a method other than Method X and Method Y. For example, the mobile NW 40 or the rescue support device 30 may be equipped with a camera, and the rescue support device 30 may acquire the damage situation from an image captured by the camera.

[0042] <Information Collection Patterns> There are two methods for acquiring the disaster situation and two methods for detecting the status of the terminal or user, so there are four methods (four patterns) of information collection methods as described below. In this embodiment, the rescue support device 30 uses information collected by any one of the four patterns to recreate the actual situation on Digital Twin (i.e., on a computer), and analyzes the situation to analyze the possibility that rescue is necessary for the user (the need for rescue), and provides the analysis results to the information destination 60. Note that only one of the following four patterns may be implemented, or multiple of the following four patterns may be implemented.

[0043] (1) Pattern A (detection of device unavailability) and X (Japan Meteorological Agency data) Using Japan Meteorological Agency data and information on detected device unavailability (users being unable to use their devices), victims who are unable to report due to device failure are identified. The detection target is water damage or device failure. The granularity of the estimated damage situation is in units of area (city, ward, town, village, etc.).

[0044] (2) Patterns A (detection of device unavailability) and Y (wireless sensing) Using the damage situation estimation results from wireless sensing and information on detected device unavailability, victims who are unable to report due to device failure are identified. The detection target is submerged or broken devices. The damage situation estimation granularity is in units of buildings or natural objects.

[0045] (3) Pattern B (detection of a state in which a user is unable to move) and X (Japan Meteorological Agency data) Using Japan Meteorological Agency data and information on the detection of a state in which a user is unable to move, victims who are unable to move due to the disaster are identified. The detection target is a state in which a user is unable to move. The granularity of the damage situation estimation is in units of area (city, ward, town, village, etc.).

[0046] (4) Patterns B (detection of a state in which a user is unable to move) and Y (wireless sensing) Using information on the damage situation estimated by wireless sensing and the detection of a state in which a user is unable to move, victims who are unable to move due to the disaster are identified. The detection target is a state in which a user is unable to move. The granularity of the damage situation estimation is in units of buildings or natural objects.

[0047] (Processing Sequence) An example of a processing sequence will be described with reference to Fig. 4. In the sequence of Fig. 4, the steps numbered a, b, x, and y correspond to the above-mentioned processes A, B, X, and Y, respectively.

[0048] In S1x (step 1x), the rescue support device 30 receives, for example, disaster occurrence information, area-specific seismic intensity information, or tsunami height information as Japan Meteorological Agency data from the Japan Meteorological Agency 50. In S1y, the rescue support device 30 receives, as a result of wireless sensing performed by the mobile NW 40, information indicating that a disaster has occurred at a certain location.

[0049] In S2a, communication with the terminal is interrupted. In S2b, communication with the terminal is not interrupted, but the mobile NW 40 detects through wireless sensing that the user of the terminal is not physically active.

[0050] In S3 a, the rescue support device 30 receives the communication status (such as communication disruption) and location information of the terminal from the mobile NW 40.

[0051] In S3b, the rescue support device 30 receives, from the mobile NW 40, the wireless sensing result (no physical activity) of the user of the terminal and the location information of the user (terminal).

[0052] In S4, the rescue support device 30 calculates the possibility that the user of the terminal needs rescue. The "possibility that rescue is necessary" may be rephrased as "necessity of rescue." More specifically, the rescue support device 30 executes the following process.

[0053] In S4-1-a, the rescue support device 30 calculates the possibility that rescue is required for the user of each terminal, using the communication status of the terminal, location information of the terminal, time-series data of the communication status / location information of the terminal, information from the Japan Meteorological Agency / disaster situation estimation results obtained by wireless sensing, etc. "Calculating the possibility" includes determining whether rescue is required.

[0054] In S4-1-b, the rescue support device 30 calculates the possibility that rescue is required for the user of the terminal using the wireless sensing results for the user of the terminal, the user's location information, time series data of the user's wireless sensing results / location information, and information from the Japan Meteorological Agency / results of damage situation estimation by wireless sensing, etc.

[0055] In S4-2, the rescue support device 30 corrects the possibility that rescue is necessary for the user by using, for example, information about the surroundings of the terminal user. For example, if there is a cliff or the like that is prone to collapse around the terminal user, the possibility that rescue is necessary is increased.

[0056] In S5, the rescue support device 30 provides the information recipient 60 with information about users who are likely to need rescue.

[0057] (Specific Examples) Specific examples of analysis by the rescue support device 30 will be described below for each pattern.

[0058] <(1) Pattern: A-X> In pattern "A-X," the rescue support device 30 analyzes the possibility that rescue is necessary for the user of the terminal, using the damage situation estimation based on data from the Japan Meteorological Agency, the communication status of the terminal, and the location information of the terminal. A specific example will be described with reference to FIGS. 5 and 6.

[0059] 5 is a diagram showing a disaster situation, information on detected unavailability of terminals, and location information of each terminal (each user) reproduced in a virtual space by the rescue support device 30. The information in this diagram may be actually displayed on the information destination 60 (terminal, etc.), or may be digital information stored in the rescue support device 30.

[0060] In the example of Fig. 5, disaster information from the Japan Meteorological Agency is mapped on a map. In addition, location information of multiple terminals (i.e., location information of multiple users) is mapped on the map. In the example of Fig. 5, it is shown that communication with the terminal of the user indicated by D has been interrupted. The map here may be a general 2D map or a 3D map.

[0061] The rescue support device 30 determines whether there are any users who are likely to need rescue based on the data mapped on the map. Figure 6 shows that user D has been determined to be a user who is likely to need rescue. For example, the rescue support device 30 determines that user D is a user who is likely to need rescue because communication with user D's terminal has been interrupted and the terminal is located in an area where the seismic intensity has been high (for example, an area where the seismic intensity is above a threshold).

[0062] <(2) Pattern: A-Y> In pattern "A-Y," the rescue support device 30 analyzes the possibility that rescue is necessary for the user of the terminal, using the damage situation estimation by wireless sensing, the communication status of the terminal, and the location information of the terminal. A specific example will be described with reference to FIGS. 7 and 8.

[0063] 7 is a diagram showing a disaster situation, information on detected unavailability of a terminal, and location information of each terminal (each user) reproduced in a virtual space by the rescue support device 30. The information in this diagram may be actually displayed on the information destination 60 (terminal, etc.), or may be digital information stored in the rescue support device 30.

[0064] In the example of Fig. 7, changes in artificial or natural objects detected by wireless sensing are mapped on a map. Furthermore, location information of multiple terminals (i.e., location information of multiple users) is also mapped on the map. Furthermore, the example of Fig. 7 indicates that communication with the terminals of users D and E has been interrupted. The map here may be a 2D map or a 3D map.

[0065] The rescue support device 30 determines whether there are any users who are likely to need rescue based on the data mapped on the map. Figure 8 shows that user D (user of terminal D) and user E (user of terminal E) are determined to be users who are likely to need rescue.

[0066] For example, the rescue support device 30 determines that user D is likely to need rescue because communication with user D's terminal has been cut off and the terminal is located in an area affected by a tsunami / flood.

[0067] Furthermore, the rescue support device 30 determines that user E is likely to require rescue because communication with the terminal of user E continues but the building at that location is damaged.

[0068] <(3) Pattern: B-X> In pattern "B-X," the rescue support device 30 analyzes the possibility that rescue is necessary for the user of the terminal, using damage situation estimation based on data from the Japan Meteorological Agency, information on the user's physical activity obtained by wireless sensing, and location information of the user (terminal). A specific example will be described with reference to FIGS. 9 and 10 .

[0069] 9 is a diagram showing a disaster situation, information on the physical activity of each user, and location information of each terminal (each user) reproduced in a virtual space by the rescue support device 30. The information in this diagram may be actually displayed on the information destination 60 (terminal, etc.), or may be digital information stored in the rescue support device 30.

[0070] In the example of Fig. 9, disaster information from the Japan Meteorological Agency is mapped on a map. Furthermore, location information of multiple devices (i.e., location information of multiple users) is also mapped on the map. In the example of Fig. 9, the user indicated by D is not physically active. The map here may be a typical 2D map or a 3D map.

[0071] The rescue support device 30 determines whether there are any users who are likely to need rescue based on the data mapped on the map. Fig. 10 shows that user D has been determined to be a user who is likely to need rescue. For example, the rescue support device 30 determines that user D is a user who is likely to need rescue because user D is not physically active and is located in an area where the seismic intensity was high (for example, an area where the seismic intensity is above a threshold).

[0072] <(4) Pattern: B-Y> In pattern "B-Y," the rescue support device 30 analyzes the possibility that rescue is necessary for the user of the terminal, using the disaster situation estimation by wireless sensing, the information on the user's physical activity by wireless sensing, and the user's location information. A specific example will be described with reference to FIGS. 11 and 12 .

[0073] 11 is a diagram showing a disaster situation, information on the physical activities of each user, and location information of each terminal (each user) reproduced in a virtual space by the rescue support device 30. The information in this diagram may be actually displayed on the information destination 60 (terminal, etc.), or may be digital information stored in the rescue support device 30.

[0074] In the example of Fig. 11, changes in artificial or natural objects detected by wireless sensing are mapped on a map. Furthermore, location information of multiple devices (i.e., location information of multiple users) is mapped on the map. Furthermore, the example of Fig. 11 indicates that users D and E are not physically active. The map here may be a 2D map or a 3D map.

[0075] The rescue support device 30 determines whether there are any users who are likely to need rescue based on the data mapped on the map. Figure 12 shows that users D and E are determined to be users who are likely to need rescue.

[0076] For example, the rescue support device 30 determines that user D is likely to need rescue because user D is not physically active and is located in an area affected by a tsunami / flood.

[0077] Furthermore, the rescue support device 30 determines that user E is likely to need rescue because user E is not physically active and the building at that location is damaged.

[0078] (Effects of the embodiment) The technology according to the embodiment makes it possible to support the rescue of disaster victims when a disaster occurs. More specifically, if a disaster victim has a terminal, a notification is automatically sent to family members or public institutions, which can lead to the rescue of the disaster victim.

[0079] (Modification) Next, a modification will be described. The examples described so far are referred to as basic examples. In the modification, the technology described in the basic example is used to calculate information useful for formulating a disaster prevention plan. That is, in the modification, the rescue support device 30 performs analysis on Digital Twin based on information on past disasters and disaster simulation information such as building collapse, and calculates the possibility that the user of the terminal will need to be rescued. The calculation result is used in formulating a disaster prevention plan.

[0080] The information used by the rescue support device 30 to calculate the possibility that rescue is necessary is basically the same as the information in the basic example, that is, the same as the information obtained by the above-mentioned methods A, B, X, and Y. However, in the modified example, simulated information is used instead of actual information.

[0081] The simulation information is information about future damage predicted from, for example, past information, topography, etc., regarding the damage situation.

[0082] In addition, with regard to detecting the user's status, the simulation information includes, for example, location information of terminals that will be unable to communicate in the event of a disaster, predicted (simulated) from the current communication status and location information of the terminal and simulation information regarding the disaster situation, and location information of users who are detected as not being physically active by wireless sensing.

[0083] <System Configuration and Operation> An example of a system configuration in a modified example is shown in Fig. 13. As shown in Fig. 13, a mobile network 40 and a public institution 55 are connected to a rescue support device 30. The public institution 55 is, for example, an institution that provides simulation information related to disasters. A terminal 20 held by a user is connected to the mobile network 40.

[0084] An example of a processing sequence will be described with reference to Fig. 13. In the description of the processing in the sequence, the processes with step numbers a and b correspond to the above-mentioned processes A and B, respectively.

[0085] In S11, the rescue support device 30 receives simulation information on disasters from the public institution 55. The simulation information on disasters is, for example, simulation information on building collapses, landslides, tsunamis, floods, and the like.

[0086] In S12 , the rescue support device 30 receives the communication status and location information of the terminal from the mobile NW 40 .

[0087] In S13, the rescue support device 30 calculates the possibility that the user of the terminal needs rescue based on the simulation information received in S11. More specifically, the rescue support device 30 executes the following process.

[0088] In S13-1, the rescue support device 30 generates predicted data for the communication status, time-series data, and wireless sensing state of each terminal in the event of a disaster based on the information acquired in S11 and S12. The subsequent information for the terminal is based on the predicted data.

[0089] In S13-1-a, the rescue support device 30 calculates the possibility that rescue is required for the user of the terminal using the communication status of the terminal, the location information of the terminal, time series data of the communication status / location information of the terminal, and disaster simulation information, etc.

[0090] In S13-1-b, the rescue support device 30 calculates the possibility that rescue is required for the user of the terminal using wireless sensing results for the user of the terminal, the user's location information, time series data of the user's wireless sensing results / location information, and disaster simulation information, etc.

[0091] In S13-2, the rescue support device 30 corrects the possibility that rescue is necessary for the user of the terminal, for example, by using information about the surroundings of the user of the terminal.

[0092] In S14, the rescue support device 30 provides the calculation result in S13 to the public institution 55. Note that the information may be provided to an entity other than the public institution 55.

[0093] Specific examples in the modified example are similar to the examples in the basic example explained with reference to Figures 5 to 12. However, in the modified example, the analysis contents shown in Figures 5 to 12 are based on simulation information.

[0094] (Effects of the Modification) According to the modification, it becomes possible to efficiently formulate a disaster prevention plan in the event of a disaster.

[0095] (Device Configuration) Next, an example of the functional configuration of the rescue support device 30 that performs the processes and operations described above will be described.

[0096] Fig. 15 is a diagram showing an example of the functional configuration of the rescue support device 30. As shown in Fig. 15, the rescue support device 30 has a transmitting unit 310, a receiving unit 320, a setting unit 330, and a control unit 340. The functional configuration shown in Fig. 15 is merely an example. The names of the functional divisions and functional units may be any as long as they can perform the operations according to the embodiment of the present invention.

[0097] The transmitter 310 has a function of generating a signal to be transmitted to another device and transmitting the signal via a wired or wireless connection. The receiver 320 has a function of receiving various signals transmitted from other devices and acquiring, for example, information of a higher layer from the received signals. A communication unit including the transmitter 310 and the receiver 320 may be configured.

[0098] The setting unit 330 stores preset setting information and various setting information to be transmitted to other devices in a storage device, and reads the information from the storage device as needed. The control unit 340 controls the rescue support device 30. A functional unit related to signal transmission in the control unit 340 may be included in the transmitting unit 310, and a functional unit related to signal reception in the control unit 340 may be included in the receiving unit 320.

[0099] (Hardware Configuration) The block diagram ( FIG. 15 ) used to explain the above embodiment shows functional blocks. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method for realizing each functional block is not particularly limited. That is, each functional block may be realized using a single device that is physically or logically coupled, or may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wires, wirelessly, etc.) and these multiple devices.
