[0066] Referring to FIGS. 2a and 2b, an integrated disaster prevention system according to one embodiment may include devices (or user devices) (200), an SOS group service server (204) that supports SOS group services, and an emergency agency server (206).

[0067] The term device (200) is used as a general term for electronic devices (101), electronic devices, smartphones, mobile devices, and wearable devices (201), and may be replaced with terms such as accident device, master device, and user device in describing the present disclosure.

[0068] The device (200) may include at least one of an electronic device (101) (e.g., a smartphone) and a wearable device (201) (e.g., a smart watch). The electronic device (101) may be used as a means to transmit and receive data by communicating with an SOS group service server (204) and to transmit and receive data by communicating with another user's electronic device (101). The electronic device (101) and / or the wearable device (201) may be used as a means to determine the user's biometric information and whether an emergency / crisis situation has occurred.

[0069] For example, the drawing of FIG. 2a illustrates an environment in which users A, B, and C are grouped together. User A uses an electronic device (101) (e.g., device (A)) and a wearable device (201) (e.g., device (A')), User B uses only the electronic device (101) (e.g., device (B)), and User C uses the electronic device (101) (e.g., device (C)) and a wearable device (201) (e.g., device (C')), but this is merely an example and is not limited thereto.

[0070] According to one embodiment, an electronic device (101) and a wearable device (201) connected to a user account can communicate with each other through a first network communication (e.g., short-range communication). The electronic device (101) and the wearable device (201) can be connected to each other via Bluetooth pairing.

[0071] The electronic device (101) supports an SOS group service based on an SOS group service application (e.g., SOS link application) and can communicate with an SOS group service server (204) via a second network communication (e.g., telecommunication or cellular communication). Each electronic device (101) (e.g., device (A), device (B), device (C)) can communicate with each other via at least one of a first network communication (e.g., short-range communication) and / or a second network communication (e.g., telecommunication or cellular communication).

[0072] According to one embodiment, the SOS group service server (204) operates a platform for providing SOS group services to users based on an SOS group service application and can transmit and receive data via a network with at least one device (e.g., electronic device (101)) and an emergency agency server (206) in relation to the SOS group service.

[0073] According to one embodiment, the SOS group service server (204) communicates with a plurality of devices connected / linked to a group to monitor user activity and can detect / recognize the occurrence of an emergency / critical situation (e.g., fall accident, distress, physical condition abnormality, etc.). According to one embodiment, at least one of the plurality of devices connected / linked to a group can determine that an emergency / critical situation has occurred at any one device within the group and transmit information regarding the occurrence of the emergency / critical situation to the SOS group service server (204).

[0074] The SOS group service server (204) can guide the devices included in the group to make a rescue report (e.g., 119 report, 112 report) or to make a rescue report through a device optimized according to the situation. The SOS group service server (204) can provide an operating environment that enables synchronized rescue signals (e.g., SOS sound / light) to be output simultaneously from all devices within the group. According to one embodiment, the SOS group service server (204) can provide an operating environment that outputs rescue signals by selecting an optimized output method (sequential output or simultaneous output) according to the situation of all devices within the group.

[0075] The SOS group service server (204) checks the speaker performance and light-emitting device (e.g., LED, flash) output performance of the devices connected / linked to the group when configuring the group, and can adjust at least one of the output intensity and output time (e.g., start timing) of the synchronized rescue signal (e.g., SOS sound / SOS light) based on the speaker performance and light-emitting device (e.g., LED, flash) output performance of the devices. For example, the SOS group service server (204) can adjust the output start timing of the rescue signal so that each device connected / linked to the group can output the rescue signal simultaneously.

[0076] The SOS group service server (204) can report to an emergency agency on behalf of the user device if there is no rescue report from the devices within the group after an emergency / critical situation is recognized. The SOS group service server (204) can communicate with the emergency agency server (206) or the rescue team to provide rescue team situation information to the devices within the group.

[0077] According to one embodiment, when an emergency situation of a user is detected through any user device in the group, the SOS group service server (204) (or master device) may attempt to establish a communication connection (or automatically report rescue) with the device of the person involved in the emergency situation (hereinafter referred to as the accident device) or notify a rescue report guide notification (e.g., 119 connection). For example, if the user selects a rescue report item displayed in the rescue report guide notification, the accident device may attempt to establish a call connection with an emergency reporting agency. For another example, if the SOS group service server (204) attempts to establish a call connection with the person involved in the emergency and determines that the call is not established or that a rescue report using the person involved in the emergency device (hereinafter referred to as the accident device) is impossible (e.g., inability to communicate, battery capacity), it may inform other users' devices in the group of the person involved in the emergency situation and notify them of a rescue report guide notification (e.g., User C accident occurred, 119 connection).

[0078] According to one embodiment, the SOS group service server (204) (or the master device within the group) can determine whether the accident device is in an environment where it cannot perform a rescue report (e.g., battery remaining capacity is below a threshold, signal strength is below a threshold, etc.). If the SOS group service server (204) (or the master device) is in an environment where the accident device can perform a rescue report (e.g., satellite connection is possible, battery remaining capacity is above a threshold, etc.), it can attempt to make a phone call to an emergency agency (or report a rescue request) using the accident device or notify the accident victim of a rescue report guide notification (e.g., call 119) to guide the accident victim to directly request a rescue report to an emergency agency. If the accident victim device is in an environment where it cannot perform an emergency rescue report, the SOS group service server (204) (or the master device) can inform other users' devices within the group of the accident victim's critical / urgent situation and notify them of a rescue report guide (e.g., User C accident occurred, call 119).

[0079] The SOS group service server (204) (or master device) may request all devices in the group to simultaneously output a rescue signal (e.g., SOS sound / light) based on the detection / recognition of the occurrence of an emergency / critical situation. Each device in the group may simultaneously output a rescue signal (or synchronized rescue signal) based on the request for rescue signal output from the SOS group service server (204) or the master device.

[0080] According to one embodiment, when the electronic device (101) of user A operates as a master device for setting up a group network, the electronic device (101) of user A may communicate with the SOS group service server (204) through a second network communication to perform various functions / operations related to monitoring activities within the group, detecting / recognizing the occurrence of an emergency situation within the group, monitoring rescue reports, and controlling the output of a rescue signal (SOS).

[0081] FIG. 2b illustrates examples of user devices according to one embodiment.

[0082] Referring to FIG. 2b, a user's device (200) according to one embodiment may include at least one of an electronic device (101) and a wearable device (201) connected to a user account. Since the electronic device (101) is the same as the electronic device (101) shown in FIG. 1, specific details will be omitted.

[0083] According to one embodiment, the wearable device (201) may include a processor (210), a communication device (220), an accelerometer (230), a gyroscope (240), a GPS device (250), a display (260), a biosensor (270), a speaker (280), and an LED device (290), but this is merely an example and some of the components shown in FIG. 2b may be omitted or other components not shown (e.g., memory) may be included.

[0084] The communication device (220) includes at least one communication circuit and, under the control of the processor (210), can control a communication connection between the wearable device (201) and at least one other electronic device (e.g., a smartphone) and / or a server (e.g., the server (108) of FIG. 1). The communication device (220) can support the establishment of a wireless communication channel with another electronic device and the performance of communication through the established communication channel. The communication device (220) can support short-range wireless communication such as UWB, Bluetooth, and low-power Bluetooth, but is not limited thereto.

[0085] The accelerometer (230) and gyroscope (240) can acquire movement information of the wearable device (201). For example, the accelerometer (230) and gyroscope (240) can detect motion, gesture, impact, fall and / or posture, and transmit the detected information to the processor (210).

[0086] The GPS device (250) may include a GPS module for providing location information of the wearable device (201).

[0087] The display (260) can visually provide various information related to the operation or function of the wearable device in conjunction with the electronic device (101).

[0088] A biosensor (270) can acquire various biometric information of a user using an optical signal. The biosensor (270) can acquire biometric information such as heart rate (HR), blood pressure, saturation of percutaneous oxygen (SpO2), galvanic skin response (GSR), electrocardiography (ECG), blood flow velocity, and bioelectrical impedance, but is not limited thereto. A processor (210) can determine biometric characteristics (e.g., photoplethysmograph (PPG), heart rate (HR), heart rate variation (HRV), oxygen saturation (SpO2), blood pressure (BP), and / or blood glucose (BG)) based on the signal pattern or change over time of biometric data transmitted from the biosensor (270).

[0089] The processor (210) can control the operation of the wearable device (201). The processor (120) can control other components included in the wearable device (201) and perform various data processing or operations. The processor (210) may include at least one of a controller, an MCU (micro controller unit) sensor, or a sensor processor sensor hub.

[0090] According to one embodiment, the wearable device (201) can be used to collect the user's biometric information and to determine whether an emergency / critical situation has occurred. The wearable device (201) can transmit and receive data related to the user's activity with the electronic device (101) and, under the control of the electronic device (101), perform functions / operations related to the SOS group service.

[0091] In the embodiments described below in FIGS. 3 to 8, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0092] FIG. 3 illustrates a method for generating a rescue report and a rescue signal using a plurality of devices in an integrated disaster prevention system environment according to one embodiment.

[0093] Referring to FIG. 3, according to one embodiment, in operation 310, an electronic device (e.g., the electronic device (101) of FIG. 1) (hereinafter, master device) can initiate group activities, connect to an SOS group service (e.g., SOS link service) to form a group connection or group network with each user device (hereinafter, device).

[0094] For example, users can run an SOS group service application (e.g., SOS link application) through their electronic device (101) and log in to the SOS group service (or SOS group service server (204)). The master device can perform a near-field communication scan operation to search for nearby devices and request a group connection with the discovered nearby devices. The master device can form a group connection or group network by receiving an acknowledgment signal for the group connection request from the nearby devices. Upon receiving an acknowledgment signal for the group connection from the device, each device can be added to a group bound by the SOS group service. The acknowledgment for each device may include authorization for monitoring device activity and sensing data.

[0095] According to one embodiment, one electronic device within a group may be designated as a master device. The master device may be a device that searches for nearby devices and requests a group connection. According to some embodiments, the master device may delegate the authority of the master device to other devices in the group.

[0096] The SOS group service server (204) can monitor devices within the group during group activities based on location information of logged-in devices and group connection / network information.

[0097] In operation 315, the SOS group service server (204) (or master device) can communicate with the devices included in the group to monitor user activities (e.g., location information, sensing information, user biometric information, etc.).

[0098] 315 Independently of or in parallel with the operation, each device may communicate with the master device through at least one of a first network (e.g., short-range communication) or a second network (e.g., long-range communication, cellular communication). For example, the master device may exchange location information with each device and, if any one device moves out of a set distance, may notify the user that a specific user has moved out of the group.

[0099] In operation 320, the SOS group service server (204) (or master device) can detect that a group emergency (or urgent / emergency) situation (e.g., a fall, abnormal body signal, etc.) has occurred.

[0100] According to one embodiment, each device can detect the occurrence of an emergency and notify the master device of the group of the occurrence of the emergency. For example, a wearable device (201) can detect a biological abnormality by determining whether biological measurements (e.g., heart rate, pulse rate, body temperature, etc.) collected from a biological sensor are outside the normal range. If a biological abnormality is detected, the wearable device (201) can notify the electronic device (101) connected to the wearable device (201) of the biological abnormality detection signal. For another example, the electronic device (101) and / or the wearable device (201) can detect the occurrence of a fall accident and notify the master device of the fall accident detection signal if a measurement measured by at least one sensor (e.g., an accelerometer and / or gyroscope) exceeds a set threshold or corresponds to a fall threshold. The master device can transmit the emergency occurrence information to the SOS group service server (204).

[0101] According to one embodiment, if the master device itself detects a fall accident or biological abnormality, the master device may notify other devices in the group of the occurrence of its emergency situation and request delegation of the master role.

[0102] In operation 325, the SOS group service server (204) (or master device) can control the simultaneous output of SOS sound / light (or synchronized distress signal) across all group devices [pre-report situation].

[0103] According to one embodiment, an SOS group service server (204) or a master device may transmit at least one of a distress signal pattern (e.g., an SOS sound or an SOS light pattern) and time sync information to other devices within the group and request a distress signal output. Each of the other devices within the group may simultaneously output an SOS sound / light at the time sync time based on the distress signal output request transmitted from the SOS group service server (204) or the master device.

[0104] According to one embodiment, the operation of controlling the simultaneous output of structural signals may be processed primarily by the SOS group service server (204), but may also be operated under the control of the master device when communication between the SOS group service server (204) and the devices is impossible.

[0105] In operation 330, the SOS group service server (204) or the master device can determine whether the accident device status is in a state where it is possible to perform a rescue report.

[0106] For example, the SOS group service server (204) or the master device communicates with the accident victim's device (hereinafter, accident device) to check information on the device status (e.g., remaining battery capacity, wireless signal strength (e.g., satellite, cellular signal), network connection status, sound output capability), and if the wireless signal strength / battery status is n% or higher, it can determine that the device is in a state where a rescue report can be made.

[0107] In operation 335, if the SOS group service server (204) or the master device determines that the accident device is in a state where it can make a rescue report (in operation 330, yes), it can guide the accident device to make a rescue report directly (e.g., 119, 112).

[0108] For example, the SOS group service server (204) may attempt to make a phone call to the accident device to speak with the person involved in the accident or display a rescue report guide notification (e.g., 119 call) on the display. The person involved in the accident may attempt to make a rescue report directly by selecting a rescue report item displayed on the display to attempt to make a phone call to an emergency agency.

[0109] In operation 340, the SOS group service server (204) can determine whether a rescue report has been completed directly through the accident device.

[0110] For example, the SOS group service server (204) can communicate with the accident device to check whether the accident device attempts to make a phone call to an emergency agency and whether the report has been completed based on the phone connection history information.

[0111] In operation 345, the SOS group service server (204) can guide other devices in the group to make a rescue report if the device in distress is unable to make a rescue report (in operation 330, no) or if a rescue report is not made through the device in distress (e.g., if a report is not made despite being provided with a report guide) (in operation 340, no).

[0112] For example, the SOS group service server (204) can display information about the emergency situation of the device involved in the accident and a rescue reporting guide notification (e.g., 119 call) on the display to other devices in the group. Other users can identify the emergency situation and select a rescue reporting item displayed on the display to attempt to connect with an emergency agency.

[0113] According to one embodiment, the SOS group service server (204) can notify all other devices in the group of emergency situation information and rescue reporting guide notifications (e.g., 119 report) when one person in the group is involved in an accident.

[0114] According to one embodiment, the SOS group service server (204) may select a first device among all other devices in the group to notify a rescue report guide notification (e.g., 119 report) when one accident occurs in the group, and if no rescue report is made through the first device, select a second device (or a third device, a N device) of the next rank to notify a rescue report guide notification (e.g., 119 report) and monitor whether a rescue report is made. For example, the first device may be selected based on at least one of the device located closest to the accident device among other devices in the group, the device with the strongest communication signal strength or / and the device with the highest remaining battery capacity.

[0115] In operation 350, the SOS group service server (204) monitors whether other devices in the group have reported a rescue, and in operation 355, the SOS group service server (204) can determine whether a rescue report has been completed through other devices in the group.

[0116] In operation 360, if no rescue report is made through other devices in the group (in operation 355, no), the SOS group service server (204) can make a rescue report to an emergency agency on its own, along with information about the victim's emergency situation. In this case, since the SOS group service server (204) is monitoring the location information of the devices included in the group, it can inform the emergency agency of the victim's location.

[0117] In the 365 operation, the SOS group service server (204) or the master device may notify each of the devices included in the group to output SOS service information related to the emergency situation on the display when the rescue report is completed (e.g., yes in the 340 operation or yes in the 355 operation).

[0118] For example, the SOS group service server (204) can communicate in real time with the emergency agency dispatched by the rescue report to inform the emergency agency of the emergency situation within the group or report the rescue situation, and can notify the devices included in the group of the rescue situation reporting information.

[0119] In operation 370, the SOS group service server (204) can communicate with the emergency agency to check whether the rescue team has arrived within n meters of the accident device.

[0120] In operation 375, the SOS group service server (204) or master device can control the simultaneous output of a rescue signal (e.g., SOS sound / light) (or synchronized rescue signal) at maximum output from all devices included in the group when a rescue team comes within a set threshold distance (e.g., n meters) from the accident device (in operation 370, yes).

[0121] For example, the SOS group service server (204) can determine at least one of sound or light emission as a rescue signal by analyzing at least one of the characteristics of each device in the group (e.g., maximum volume output information, light emission characteristics, battery capacity information), situation information (e.g., weather, day / night), location information, and activity information (e.g., hiking, fishing, riding, etc.). As another example, the SOS group service server (204) can control the output of the rescue signal to be lower than the maximum output until the rescue team is within a preset distance, and then control the output of the rescue signal to be at the maximum output when the rescue team is within a preset threshold distance. Specific details regarding the output of the rescue signal will be explained in FIGS. 4a through 8.

[0122] According to one embodiment, the SOS group service server (204) or master device may have a different threshold distance (n meters) for outputting a rescue signal at maximum output based on at least one of characteristic information of the devices in the group (e.g., SOS signal, whether SOS light can be emitted), condition information of the devices (e.g., battery capacity), location information of each device, activity information of each device, and / or rescue signal characteristics of each device.

[0123] The SOS group service server (204) or master device can proceed to operation 365 if the rescue team does not approach within n meters of the accident device (in operation 370, no).

[0124] In operation 380, the SOS group service server (204) monitors the rescue completion status and can terminate the process of Figure 3 if the rescue is completed (in operation 375, yes). If the rescue is not completed (in operation 375, no), the SOS group service server (204) can proceed to operation 375.

[0125] FIGS. 4a to 4c illustrate examples of various user interface screens related to an SOS group service of an electronic device according to one embodiment.

[0126] Referring to FIGS. 4a through 4c, an electronic device (101) (or processor (120)) according to one embodiment may provide various user interface (UI) screens related to an SOS group service to a user through a display. FIG. 4a shows screens related to group settings displayed on a device (e.g., electronic device A, wearable device A'), FIG. 4b shows screens related to the occurrence of an emergency situation displayed on a device (e.g., electronic device A, wearable device A'), and FIG. 4c shows screens related to the occurrence of an emergency situation displayed on an accident device (e.g., electronic device C, wearable device C'). The interface configurations illustrated in FIGS. 4a through 4c are described only as examples and are not limited thereto.

[0127] Based on the execution of the SOS group service application by electronic device A (e.g., electronic device (101)). <401> As illustrated in [Image], a first UI screen (410) supporting group connection may be displayed on the display. The first UI screen (410) includes a list of devices (420) discovered for the SOS group, a group network diagram (421), a connection approval item (430), and a connection rejection item (435), but is merely an example and is not limited thereto. On the first UI screen (410), one's own device (e.g., Device A (me)) and other user devices (e.g., Device B, Device C) may be displayed so as to be visually distinguishable. The group network diagram (421) may display a connection relationship among at least one of a server (e.g., SOS Link), an electronic device (101), and a wearable device (201). If electronic device A is connected to wearable device A' via a user account, wearable device A' also <402> As illustrated in [Image], a list of devices (4100) based on the SOS group service may be displayed. The electronic device (101) and the wearable device (201) can communicate with each other and perform functions / operations related to detecting an emergency based on user activity, reporting a rescue, and outputting a rescue signal.

[0128] Based on user input (440) selecting a connection approval item (430) on the first UI screen (410), the electronic device (101) can start an SOS group service with other devices connected / linked to the group. The SOS group service may refer to a service in which a server, device A, device B, and device C communicate with each other to monitor emergency situations / accidents and support the simultaneous output of rescue reports and rescue signals in the event of an accident.

[0129] When an emergency is detected in device C while monitoring group activities, the electronic device (101) <403> As illustrated in the figure, a second UI screen (411) providing a guide notification for emergency situations and rescue reporting within the group may be displayed. The second UI screen (411) may include emergency situation information (450) and rescue reporting items (455) of the person involved in the accident, an SOS output indicator (460), and a termination item (465). At this time, the wearable device (201) linked with the electronic device (101) <404> As illustrated in the figure, a rescue report item (455), an SOS output indicator (460), and a termination item (465) may be displayed. For example, the SOS output indicator (460) may include at least one of information on the rescue signal output method (sound or light), the rescue signal output time, or the time given until the report. The information displayed by the SOS output indicator (460) is merely an example and may include various information related to the SOS rescue.

[0130] For other devices in the group that are not the accident device, the SOS group service server (204) can induce them to report for rescue through the rescue signal output and rescue report item (455) for, for example, for a period of 10 seconds. If there is no rescue report from other devices for 10 seconds, the SOS group service server (204) can report for rescue on its own.

[0131] On the other hand, if the fault device is C, the fault device is <405> As illustrated in [Image], a third UI screen (470) providing a rescue report guide notification may be displayed. The third UI screen (470) may notify of an abnormal signal occurrence (475) and may include an emergency rescue report item (455), an SOS output indicator (460), and a termination item (465). Device C' connected to device C also, <406> As illustrated in [Image], a rescue report item (455), an SOS output indicator (460), and a termination item (465) may be displayed. In the case of accident device C, the SOS group service server (204) may induce a rescue report via the rescue signal output and rescue report item (455) for, for example, for a period of 5 seconds. If there is no rescue report using accident device C for 5 seconds, the SOS group service server (204) <403> and <404> You can induce people to report a rescue through other devices within the group, such as this.

[0132] FIG. 5a illustrates a method of outputting an SOS sound using at least one electronic device in an integrated disaster prevention system environment according to one embodiment, and FIG. 5b illustrates a diagram for explaining the resonance frequency of the SOS sound according to one embodiment.

[0133] Referring to FIGS. 5a and 5b, according to one embodiment, an SOS group service server (204) or a master device can recognize the occurrence of an emergency detected by any one device in the group in operation 510.

[0134] For example, when the accident device detects the occurrence of an emergency, it may notify the master device within the group or the SOS group service server (204) of the occurrence of the emergency.

[0135] In operation 515, the SOS group service server (204) or master device can determine whether the group consists of multiple devices.

[0136] In operation 520, the SOS group service server (204) or the master device can determine whether the group is composed of multiple devices (yes in operation 515) and whether any of the multiple devices are exposed to the outside.

[0137] When setting up an SOS group, the SOS group service server (204) can monitor the status of each device by periodically transmitting and receiving device characteristics (e.g., speaker performance, light emission performance, etc.) and device data (e.g., battery capacity, sensor information, etc.) of the devices included in the group at set intervals during the group service period. For example, each device can determine whether the device is in an externally exposed state or in a stored state, such as in a bag or clothing pocket, based on sensor data obtained from at least a sensor (e.g., light sensor, proximity sensor).

[0138] In operation 525, the SOS group service server (204) or the master device can determine whether one device is externally exposed when the group consists of one device (in operation 515, no).

[0139] In operation 530, the SOS group service server (204) or the master device can control the output of an SOS sound to one device when one device is exposed to the outside (in operation 525, yes).

[0140] For example, the SOS group service server (204) or master device transmits an emergency situation occurrence signal and an SOS sound output request signal to one device exposed to the outside, and the device can play the SOS sound for a preset time.

[0141] In operation 540, the SOS group service server (204) or master device can select the first device having the largest output performance speaker among the devices exposed to the outside within the group.

[0142] In operation 550, the SOS group service server (204) or master device may request that devices exposed inside or outside the group be set to sound mode and maximum output performance.

[0143] In operation 560, the SOS group service server (204) or master device can synchronize the time sync of other devices based on the first device.

[0144] In operation 570, the SOS group service server (204) or master device can request / control the output of an SOS sound with a resonant frequency component across all devices in the group based on a time sync synchronized with the first device.

[0145] For example, as illustrated in FIG. 5b, assuming device A is the first device, the time sync can be determined based on the time of output of the first SOS sound (5100) of device A. At the time of output of the first SOS sound (5100) of device A, device B can output a second SOS sound (5200) in time sync with the resonant frequency component of the first SOS sound (5100) of device A. Then, as the first SOS sound (5100) of device A and the second SOS sound (5200) of device B resonate, an SOS sound (5300) with a relatively large amplitude can be output, as illustrated in FIG. 5b.

[0146] In operation 580, the SOS group service server (204) or the master device may guide a device to perform only a rescue report if one device is not in an externally exposed state (in operation 525, no), or if there are no externally exposed devices among multiple devices in the group (in operation 520, no). For example, the SOS group service server (204) or the master device may notify each device of a rescue report guide notification.

[0147] FIG. 6a illustrates a method of generating using at least one electronic device in an integrated disaster prevention system environment according to one embodiment, and FIG. 6b illustrates a diagram for explaining the time sync of an SOS light emission pattern according to one embodiment.

[0148] Referring to FIGS. 6a and 6b, according to one embodiment, an SOS group service server (204) or a master device can recognize the occurrence of an emergency detected in any one of the devices in the group in operation 610.

[0149] For example, when the accident device detects the occurrence of an emergency, it may notify the master device within the group or the SOS group service server (204) of the occurrence of the emergency.

[0150] In operation 615, the SOS group service server (204) can distinguish whether the time of the emergency is evening / night. For example, the SOS group service server (204) can distinguish evening / night based on sunset time.

[0151] In operation 620, the SOS group service server (204) can determine whether light is needed at the location of the accident if the time of the emergency is during the day (no in operation 615). For example, the SOS group service server (204) can determine that light is needed if the location of the accident is a place where darkness exists, such as in the mountains, and the group is engaged in activities.

[0152] In operation 625, the SOS group service server (204) or the master device can determine whether the group is composed of multiple devices if the time of the emergency is evening / night (yes in operation 615) or if light is needed at the location of the accident (yes in operation 620).

[0153] In operation 630, the SOS group service server (204) can determine whether there are any devices among the group's multiple devices that are exposed to the outside. Since operation 630 is identical to operation 520 of FIG. 5a, a detailed description will be omitted.

[0154] In operation 635, the SOS group service server (204) can control the SOS light output using one device when the emergency situation occurs to one device rather than multiple devices (in operation 620, no). For example, the SOS group service server (204) can request an SOS light output to one device. The device that receives the SOS light output request can output a rescue signal according to the SOS light pattern using a light-emitting device (e.g., LED, flash).

[0155] In operation 640, the SOS group service server (204) or master device can select a first device having the brightest light emission performance among the devices exposed to the outside within the group and determine the time sync of the light emission pattern based on the first device.

[0156] In operation 650, the SOS group service server (204) or master device can request / control devices exposed inside and outside the group to output a distress signal according to an SOS light pattern based on a determined time sync.

[0157] For example, as illustrated in FIG. 6b, if device A is assumed to be the first device, the time sync can be determined based on the LED light emission pattern and the output time in device A. When device A outputs an LED light emission pattern (6100) as illustrated in FIG. 6b, device B outputs an LED light emission pattern (6200) synchronized according to the time sync time, and device C can also output an LED light emission pattern (6300) synchronized according to the time sync time.

[0158] In operation 660, the SOS group service server (204) may be guided not to output an SOS light signal (e.g., LED) if light is not needed at the location of the accident (in operation 620, no) or if there are no devices exposed outside the group (in operation 630, no).

[0159] FIG. 7 illustrates a method of generating a rescue report and a rescue signal using a plurality of electronic devices in an integrated disaster prevention system environment according to one embodiment.

[0160] Referring to FIG. 7, an electronic device (101) according to one embodiment can execute an SOS group service function based on user input before group activity in operation 710.

[0161] For example, the electronic device (101) can execute the SOS group service application based on user input requesting the execution of the SOS group service application and communicate with the SOS group service server (204) to display a UI screen related to the SOS group service on the display. The electronic device (101) can search for nearby devices logged into the SOS group service for SOS group settings and then display a list of the searched nearby devices on the UI screen. At this time, the nearby devices may include at least one electronic device (e.g., mobile device (101) and wearable device (201)) linked to a user account.

[0162] In operation 720, the electronic device (101) can set up an SOS group of peripheral devices based on an input that establishes a group connection with the discovered peripheral devices.

[0163] In operation 730, the electronic device (101) can check whether it is set as a master device.

[0164] For example, the electronic device (101) may support a master device function that controls the rescue signal output on behalf of the SOS group service server (204). The electronic device (101) may be set as a master device when real-time communication between the SOS group service server (204) and other devices within the group is not possible.

[0165] In operation 735, if the electronic device (101) is not set as a master device (in operation 730, no), it may output a rescue signal (e.g., SOS sound / light) upon request from the SOS group service server (204) when an emergency situation within the group is detected.

[0166] For example, when the SOS group service server (204) recognizes an emergency situation within the group, it may request the output of a rescue signal to all devices included in the group. The SOS group service server (204) may transmit SOS sound / lighting pattern information and time sync information to all devices within the group to control all devices within the group to output an SOS sound or an SOS light pattern with the same pattern.

[0167] In operation 740, if the electronic device (101) is set as the master device (in operation 730, yes), it can determine whether an SOS sound source for group service is stored in the devices within the group.

[0168] Group SOS sound source may refer to an alarm sound output when an emergency occurs in relation to the SOS Group service, and this may have a pattern different from the national disaster text message alarm sound.

[0169] For example, an electronic device (101) operating as a master device can communicate with other devices in a group to receive data related to device settings and can check the device setting information of each device.

[0170] In operation 750, the electronic device (101) can determine a time sync for the simultaneous output of a distress signal if an SOS sound source for an SOS group service is stored or set (in operation 740, yes). For example, the time sync may include an SOS sound output time or a sound / light pattern.

[0171] In operation 755, the electronic device (101) can transmit time sync information to other devices in the group and control the output of a structural signal.

[0172] In operation 760, the electronic device (101) can generate a distress signal pattern (e.g., SOS sound / light pattern) if no SOS sound source for the SOS group service is stored or set (in operation 740, no). In operation 765, the electronic device (101) can transmit the generated distress signal pattern to other devices in the group and proceed to operation 750.

[0173] FIG. 8 illustrates a method for determining an SOS sound output method in an integrated disaster prevention system environment according to one embodiment.

[0174] Referring to FIG. 8, an SOS group service / function according to one embodiment can determine the sound output method based on the distance from the rescue team, the remaining battery level, and whether the signal patterns of a plurality of devices are similar.

[0175] In operation 810, the electronic device (101) or the SOS service server device (204) can recognize that a rescue report has been made using the devices in the group when an emergency / crisis occurs.

[0176] In operation 820, the electronic device (101) can check the list of devices in the group and the status of the devices.

[0177] For example, the electronic device (101) can communicate with each device in the group to receive and verify information regarding the list of devices connected to the group network and the status of each device (remaining battery capacity, SOS signal generation pattern, storage status, etc.).

[0178] In operation 830, the electronic device (101) can communicate with the rescue team to determine if there is more than a critical distance remaining between the devices and the rescue team.

[0179] In operation 840, the electronic device (101) can determine whether the remaining battery of each device is greater than the threshold when the distance from the place where the group is located to the rescue team is greater than the threshold distance (in operation 830, yes).

[0180] In operation 850, the electronic device (101) can determine whether the remaining battery of each device is above a threshold (in operation 840, yes), the similarity of the distress signals (e.g., SOS sound patterns) of each device.

[0181] In operation 860, the electronic device (101) may request / control the output of a rescue signal in a first sound output method when the rescue signals (e.g., SOS sound patterns) of each device are similar (in operation 850, yes). For example, the first sound output method may mean a method of outputting by synchronizing the start time of the rescue signal output, the output period, and the direction of transmission.

[0182] In operation 870, the electronic device (101) may request / control to output a rescue signal in a second sound output method when the rescue signals (e.g., SOS sound patterns) of each device are not similar (in operation 850, no). For example, the second sound output method may mean a method of prioritizing the simultaneous output of rescue signals only to devices within a group that have similar rescue signals (e.g., SOS sound patterns), and then sequentially outputting rescue signals of devices that do not have similar rescue signals.

[0183] In operation 880, the electronic device (101) may request / control to output a distress signal in a third sound output method when the remaining battery of each device is below a threshold (in operation 840, no). The third sound output method may mean a method of outputting distress signals sequentially by arbitrarily determining the order to conserve the batteries of devices in a group, or controlling devices with batteries below a threshold to reduce the number of distress signal outputs or not output them at all.

[0184] In operation 880, the electronic device (101) may request / control to output a rescue signal in a fourth sound output method when the distance from the location where the group is located to the rescue team is less than or equal to a threshold distance (in operation 830, no). The fourth sound output method may mean a method of outputting a rescue signal at maximum output while maintaining the first to third sound output methods.

[0185] A method for generating a rescue report and a rescue signal (SOS) using a plurality of electronic devices in an electronic device according to one embodiment may include an operation of communicating with a rescue service server to form a group network with other electronic devices located within the short-range communication range of the electronic device. A method according to one embodiment may include an operation of checking the device characteristics and status of all electronic devices connected through the group network. A method according to one embodiment may include an operation of determining a first electronic device that serves as a reference for time synchronization based on at least one of the device characteristics and status of each electronic device connected to the group network, based on the detection of an emergency situation in any one electronic device within the group network. A method according to one embodiment may include an operation of requesting other electronic devices connected to the group network to simultaneously output a rescue signal at a time synchronized with the rescue signal output time of the first electronic device.
