The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application.

A typical application scenario to which the emergency communication method, the device, and the storage medium provided in the embodiments of the present application may be applied is a user falling scenario. As shown in fig. 1, the wearable device 101 worn by the user can detect the body state of the user through a sensor, when it is detected that the user falls down, the wearable device 101 can issue a prompt, and at the same time, the display interface can display a control item "send help seeking information (SOS)" and a control item "do nothing of me", and the wearable device 101 can send the help seeking information in response to an operation instruction selected by the user to send the help seeking information, or the wearable device 101 does not stand up for a certain time after the user falls down and automatically sends the help seeking information. The wearable device 101 sends help seeking information, and relevant information of falling of the user can be sent to the target device 102 of the emergency contact of the user, so that the user is guaranteed to be timely treated.

It should be noted that, in addition to the application scenario of falling down of the user, the method, the device and the storage medium provided in the embodiment of the present application may also be applicable to other application scenarios where help-seeking information needs to be sent due to an emergency security event, for example, application scenarios where help-seeking information needs to be sent when the user threatens life, such as too fast or too slow heart rate, too low blood pressure, too low blood sugar, etc., of the user. In order to facilitate understanding of the emergency communication method and the emergency communication device provided in the embodiment of the present application, the technical solution provided in the embodiment of the present application is described below by taking an application scenario in which a user falls down as an example, and accordingly, implementation schemes in other application scenarios can be adaptively obtained.

In order to facilitate understanding of the improvements made by the emergency communication method and apparatus provided in the embodiments of the present application, a brief description is first made of the existing related art solutions. Referring to fig. 2, taking the application scenario of falling down of the user as an example, if the wearable device 101 supports a mobile communication function, for example, the wearable device 101 is internally provided with a mobile communication module, which can support mobile communication technologies such as 2G, 3G, 4G, and 5G, the wearable device 101 may access a mobile network through a nearby base station 201, and then send help-seeking information to the target device 102. However, supporting the mobile communication function may increase the power consumption of the wearable device 101, resulting in a short standby time of the wearable device 101 and frequent charging, which is inconvenient for the user, and thus the wearable device 101 may not support the mobile communication function to ensure the standby time of the wearable device 101.

If the wearable device 101 does not support the mobile communication function, the wearable device 101 may be paired with a device supporting the mobile communication function through a Bluetooth (BT) technology, for example, the paired device 202, the wearable device 101 may send help information to the paired device 202, and the paired device 202 sends the help information to the target device 102 after accessing a network. However, on the one hand, the user may not carry the pairing device 202 with him, and the pairing device 202 is not near the wearable device 101, so that the communication distance between the pairing device 202 and the wearable device 101 exceeds the bluetooth communication distance threshold, and the wearable device 101 cannot be connected with the pairing device 202; on the other hand, paired device 202 may be powered down automatically due to power exhaustion, and wearable device 101 may not be able to connect with paired device 202.

In view of this, embodiments of the present application provide an emergency communication method, an apparatus, and a storage medium, which are used to solve the problem that the wearable apparatus 101 detects an emergency security event, but the wearable apparatus 101 cannot send help information through the mobile network and the pairing apparatus 202. According to the technical scheme provided by the embodiment of the application, the problem of sending the help seeking information can be solved based on the communication between the wearable device 101 and the third-party device.

In some embodiments, the communication link for transmitting the help information is established by adopting a technical means that the wearable device 101 actively queries nearby terminal devices for interaction. In some other embodiments, the help information is transmitted by the wearable device 101 by broadcasting the help information to the surroundings.

The technical solution provided by the embodiment of the present application is initially introduced below with reference to two application scenario examples.

Exemplary application scenario one:

referring to fig. 3, taking a user fall scene as an example, the user holds the wearable device 101 with him, and after the wearable device 101 detects that the user falls down, the help-seeking information may be sent in response to an operation instruction that the user selects to send the SOS. Thereafter, as shown in the exemplary situation of fig. 3, at this time, the wearable device 101 cannot transmit help information through the base station 201 because the wearable device 101 does not support the mobile communication function, and the wearable device 101 may transmit the help information through the pairing device 202. In this case, when the wearable device 101 cannot be connected to the pairing device 202, the wearable device 101 may broadcast the assistance request information in a bluetooth broadcast manner to send an assistance request to the terminal device 301 near the wearable device 101. The environment where the user falls down may be a public place with a large traffic volume, such as a subway, a mall, a restaurant, a scenic spot, etc., people near the user have more terminal devices 301 that can access the network, furthermore, at least one terminal device 301 may receive the assistance request information, and if the holder of the terminal device 301 agrees to the assistance request, the terminal device 301 may send a response message to the wearable device 101, the wearable device 101 sends help information in response to the response message, and after receiving the help information, the terminal device 301 may send the help information to the target device 102, further in case the wearable device 101 is unable to send help information via the base station 201 and the pairing device 202, an emergency communication link is established through interaction with at least one terminal device 301 near the wearable device 101, help seeking information is sent in time, and it is ensured that a user can be rescued in time after encountering an emergency safety event.

Exemplary application scenario two:

referring to fig. 4, the difference from the exemplary scenario shown in fig. 3 is that the wearable device 101 may construct a Wi-Fi broadcast frame, encapsulate help information in the Wi-Fi broadcast frame, and then transmit the Wi-Fi broadcast frame through the wearable device 101, and after the Wi-Fi broadcast frame is received by the Wi-Fi device 401 near the wearable device 101, there is no need to transmit response information to the wearable device 101, and there is no need to complete interaction between the wearable device 101 and the Wi-Fi device. The Wi-Fi device 401 may send the help-seeking information to the server 402, and the server 402 obtains information of the contact and information related to the fall by analyzing the content of the help-seeking information, and then sends the information related to the fall to the target device 102 of the contact.

It should be noted that, in a case that the wearable device 101 does not support the Wi-Fi function, the wearable device 101 may construct a Wi-Fi broadcast frame through the bluetooth chip, and then transmit the Wi-Fi broadcast frame in the 2.4 frequency band through the front-end radio frequency system of the wearable device 101.

In the embodiment of the application, the technical scheme of broadcasting help seeking information by using Wi-Fi shown in fig. 4 is adopted, and considering that an environment where a user falls down may be a place with a small flow of people, such as an underground garage, a warehouse, a mall at a cool and clear time period, and the like, the terminal device 301 may not exist near the user, an infrastructure communication facility supporting a Wireless Fidelity (Wi-Fi) function may be used, and a device supporting the wearable device 101 to send help seeking information is not limited to the terminal device 301 shown in fig. 3, so that a device range supporting the wearable device 101 to send help seeking information is expanded, and a success rate of sending emergency help seeking information by the wearable device 101 is improved.

In this application embodiment, the wearable device 101 may be various wearable products supporting the near field communication technology that the user can wear, for example, a smart watch, a smart band, smart glasses, and the like, and the specific form of the wearable device 101 is not limited in this application embodiment.

The Near Field Communication technology may be at least one of bluetooth, wireless fidelity, Near Field Communication (NFC), Zigbee (Zigbee), Ultra Wide Band (UWB), Radio Frequency Identification (RFID), and the like. Besides NFC, several other communication technologies can control the signal transmission distance by adjusting power.

In this embodiment, the terminal device 301 may be various portable terminal products that support the short-range wireless communication technology and the mobile communication function and are carried by the user, for example, a mobile phone, a tablet computer, a PDA, a vehicle-mounted terminal, a wireless terminal in unmanned driving, a cellular phone, and the like.

In this embodiment, the target device 102 may be various portable terminal products that support the short-range wireless communication technology and the mobile communication function and are carried by the user, for example, a mobile phone, a tablet computer, a PDA, a vehicle-mounted terminal, a wireless terminal in unmanned driving, a cellular phone, and the like.

In this embodiment, the pairing device 202 may be a device that is pre-paired with the wearable device 101. Pairing may refer to the wearable device 101 bluetooth pairing with the pairing device 202. If wearable device 101 supports Wi-Fi functionality, pairing may also refer to wearable device 101 pairing with pairing device 202 Wi-Fi. The pairing apparatus 202 may be a mobile terminal product supporting various short-range wireless communication technologies and mobile communication functions, for example, a mobile phone, a tablet computer, a PDA, a vehicle-mounted terminal, a wireless terminal in unmanned driving, a cellular phone, and the like, and the specific form of the pairing apparatus 202 is not limited in the embodiment of the present application.

It is appreciated that the pairing device 202 may automatically connect with the wearable device 101 if the pairing device 202 is within an effective communication distance of the wearable device 101.

In this embodiment, the Wi-Fi device 401 may be a communication infrastructure supporting Wi-Fi functions, such as a Wi-Fi gateway, a Wi-Fi router, a Wi-Fi hotspot, and the like, and this embodiment does not limit the specific form of the Wi-Fi device 401.

Some specific types of wearable devices 101, target devices 102, pairing devices 202, terminal devices 301 and Wi-Fi devices 401 are listed above, but those skilled in the art will recognize that the embodiments of the present application are not limited to the listed types, but may be applied to any other electronic device types.

The emergency communication method provided in the embodiment of the present application is specifically described below.

In some embodiments, help information is sent by the terminal device 301 in a manner that the wearable device 101 actively queries nearby terminal devices 301 for interaction. The method can be applied to the communication system including the wearable device 101 and the terminal device 301 shown in fig. 3, the flow of the emergency communication method is exemplarily described with the embodiment shown in fig. 5, and referring to fig. 5, the method includes:

step 501, when the wearable device 101 cannot be connected to the pairing device 202, broadcasting first information, where the first information includes assistance request information.

It should be noted that, in step 501, the situation that the wearable device 101 triggers to broadcast the first information may be that when the wearable device 101 triggers to send help-seeking information after detecting an emergency safety event, the wearable device 101 cannot be connected to the pairing device 202, and thus cannot send the help-seeking information.

Optionally, step 501 may include:

step 501-1, when the wearable device 101 triggers sending help seeking information and the wearable device 101 cannot be connected with the pairing device 202, broadcasting first information.

Optionally, the help information may include help content information and contact information.

For example, the contact information may be pre-stored by the wearable device 101. The contact information may include the phone number, mailbox address, etc. of the contact. The telephone number may be a cell phone number stored within a Subscriber Identity Module (SIM) card of the contact's target device 102.

In a possible implementation, the contact information may also include the name of the contact, the relationship with the user, the address of the contact, and so on.

Alternatively, the help content information may include a name of the user, an address of the user, contents of the emergency event occurred, a time when the emergency event occurred, geographical location information of the emergency event occurred, and the like.

It should be understood that when wearable device 101 fails to connect with pairing device 202 in step 501, two situations may be involved: one situation is that in case the wearable device 101 itself does not support the mobile communication function, the wearable device 101 cannot connect with the pairing device 202; another situation is where wearable device 101 itself supports mobile communication functionality but cannot send help information over a mobile network, wearable device 101 cannot connect with pairing device 202. The emergency communication method provided by the embodiment of the application is not only suitable for the scenario that the wearable device 101 does not support the mobile communication function, but also suitable for the scenario that the wearable device 101 supports the mobile communication function but cannot send help seeking information through the mobile communication function. For example, the wearable device 101 may not be inserted with a SIM card or the SIM card may be owed, which may limit the ability of the wearable device 101 to send help information over the mobile network.

It is understood that there may be various ways in which wearable device 101 triggers sending help information.

Taking a user fall as an example for illustration, the wearable device 101 may send a reminder after detecting that the user falls. The manner in which the wearable device 101 issues the alert may be at least one of sound, vibration, display options, illuminating a screen, wherein the sound includes voice, ring tone, beep, and other various types of alert tones. For example, the wearable device 101 may specifically send out the reminder by one or a combination of two or more of voice broadcast, ringing, beeping, vibration, displaying options, and lighting up a screen. The user can respond to the reminder sent by the wearable device 101 and implement the operation instruction for sending help-seeking information to the wearable device 101, and then a manner for triggering the wearable device 101 to send help-seeking information is as follows: the wearable device 101 receives an operation instruction of sending help seeking information by a user, and triggers the sending of the help seeking information. Another way for the wearable device 101 to trigger sending help seeking information is as follows: after the user falls down, the wearable device 101 does not detect that the user stands up or the wearable device 101 does not receive an operation instruction for sending help-seeking information, which is implemented by the user, for a certain time, for example, 60s, and the wearable device 101 may directly send the help-seeking information.

It should be understood that the operation instruction for sending the help-seeking information may be implemented in various ways according to different ways of sending the reminder by the user according to the wearable device 101, which is exemplified as follows.

The first method is as follows: if the wearable device 101 is in the screen-locked state, vibration or sound reminding may be selected, for example, after the wearable device 101 detects that the user falls down, voice broadcasting is performed to "what seems to be a very heavy fall," different reminding modes may also be combined, for example, voice broadcasting is performed while vibrating, or ringing is performed while vibrating, and then the user may perform an operation instruction of sending help-seeking information to the wearable device 101 in a voice instruction mode, for example, the user may send a voice instruction "send emergency help-seeking information" or "SOS" to the wearable device 101, and after receiving the voice instruction sent by the user, the wearable device 101 sends help-seeking information.

The wearable device 101 is taken as a bracelet for exemplary illustration, and after the wearable device 101 sends out a reminder, the wearable device 101 can automatically enter a state of receiving a voice instruction, at the moment, the wearable device 101 displays the interface shown in fig. 6, and when the user sends out a voice instruction "send emergency help-seeking information", the wearable device 101 can recognize the voice instruction and execute the voice instruction. As another example, after the wearable device 101 recognizes the voice command issued by the user, the voice command issued by the user may be displayed in a text and/or sound manner for the user to determine whether the wearable device 101 correctly recognizes the voice command.

The second method comprises the following steps: the wearable device 101 may also select a mode of displaying the option to remind the user, or combine the mode of displaying the option with other reminding modes, for example, display the option while vibrating, display the option while broadcasting voice, and then the user may implement sending the help-seeking information operation instruction by touching/sliding the display interface option.

Taking the wearable device 101 as a bracelet for exemplary illustration, when the wearable device 101 selects to send out a reminder by using the display option, the display interface of the wearable device 101 displays the interface shown in fig. 7, and at this time, if the wearable device 101 is in the screen locking state, the wearable device 101 enters a touch operable state. Referring to fig. 7, the display interface of the wearable device 101 may display at least two control items, one control item is "SOS", that is, the user may manually select to send help information; another control entry is "i am not there is nothing", i.e., the user may manually choose not to send help information. As another example, the user may also select a control item by way of a gesture operation.

The third method comprises the following steps: for the reminding mode of at least one of vibration, sound, display options and lighting up screen adopted by the wearable device 101, the user can implement the operation instruction of sending help seeking information by changing the state of the part wearing the wearable device 101.

By taking the wearable device 101 as a bracelet for exemplary illustration, after the wearable device 101 detects that an emergency security event sends a prompt, the user can send help seeking information or not by changing the state of the wrist, and the wearable device 101 can detect the motion track or speed change of the wrist of the user through a sensor, identify the motion state of the wrist of the user, and then execute an operation instruction implemented by the user. For example, a user turning the wrist may indicate that help information is to be sent, and a user's wrist remaining stationary for more than a certain amount of time, e.g., 10 seconds, may indicate that no help information is to be sent.

Taking the wearable device 101 as glasses for illustration, the user may send help information or not by changing the state of the head, and the wearable device 101 may detect the motion trajectory or speed change of the head of the user through a sensor to identify the motion state of the head of the user. For example, the user's head moving up and down means sending help information, and the user's head turning left and right means not sending help information. As another example, the user may also implement an operation instruction to send help information by changing the state of the eyes and the parts around the eyes, such as turning the eyes or blinking eyes to send help information.

It should be noted that the user may implement an operation instruction for sending help-seeking information to the wearable device 101 in at least one of the first, second, and third modes.

It is understood that wearable device 101 may detect an emergency safety event. For example, the wearable device 101 may detect the body state of the user through an internally provided sensor. Use wearable device 101 to be bracelet or wrist-watch, and detect whether the user falls as the example and carry out the exemplary explanation, wearable device 101 is inside can be provided with acceleration sensor and gyroscope, and then wearable device 101 can be through analysis wrist activity orbit and impact acceleration detection user whether fall.

It should be noted that wearable device 101 may also detect emergency safety events such as too fast or too slow heart rate, too low blood pressure, too low blood sugar, etc.

For example, an optical heart rate sensor may be disposed in the wearable device 101, and it may be determined that the heart rate is too fast by detecting that the heart rate of the user is too fast or too slow, for example, the heart rate of the user exceeds 100 times per minute in a static non-ambulatory state; in a static, non-ambulatory state, the heart rate of the user is less than 60 beats per minute, and it may be determined that the heart rate is too slow.

For example, a photoelectric sensor may be disposed in the wearable device 101, and the pulse wave waveform of the wrist portion of the user is collected by the photoelectric sensor, and the blood pressure value may be estimated by analyzing parameters such as a rising slope of the pulse wave, a wave band time, and the like. For another example, the wearable device 101 may combine the pulse wave and the cardiac signal sensed by the optical heart rate sensor to calculate a blood pressure value. The wearable device 101 may detect whether the blood pressure of the user is too low through the calculated blood pressure value, such as the high pressure is lower than 90mmHg, or the low pressure is lower than 60mmHg, and may determine that the blood pressure of the user is too low.

For example, wearable device 101 may detect whether the user's blood glucose is too low by scanning a blood glucose sensor patch. The blood glucose sensor patch can be attached to the skin of a user, microneedles with the length of 1 mm-4 mm are arranged on the blood glucose sensor patch towards one side of the skin of the user, interstitial fluid under the skin of a human body can react with biochemical substances on the microneedles, the blood glucose sensor patch can store blood glucose values within a period of time, the wearable device 101 can read the blood glucose values on the blood glucose sensor patch through a close-range wireless communication technology, and therefore whether blood glucose is too low or not is detected, for example, the blood glucose values are less than 3.9, and the blood glucose of the user can be determined to be too low.

Some specific ways of detecting an emergency safety event by the wearable device 101 are listed above, but those skilled in the art can appreciate that the embodiments of the present application are not limited to the listed types, but can be applied to any other types of sensing modules and corresponding detection methods.

Alternatively, the wearable device 101 may broadcast the first information through the close range wireless communication technology. The close range wireless communication technology may be at least one of bluetooth, Wi-Fi, NFC, Zigbee, UWB, RFID. For example, the wearable device 101 may broadcast the first information through bluetooth technology, and the first information may be transmitted through a bluetooth broadcast signal. As another example, wearable device 101 may broadcast the first information over Wi-Fi, which may be transmitted over a Wi-Fi broadcast signal. As another example, the wearable device 101 may also broadcast the first information via RFID technology, and the first information may be transmitted via radio frequency signals.

It is understood that, by using the wearable device 101 in a broadcast manner, the first information may be sent to at least one terminal device 301 around the wearable device 101, where the assistance request of the first information may be a communication assistance request, and then the wearable device 101 may actively query at least one terminal device 301 existing around to construct at least one communication link for the wearable device 101 to send the help-seeking information.

Optionally, wearable device 101 may also broadcast the first information using a different close-range wireless communication technology. For example, wearable device 101 may broadcast the first information using at least two of bluetooth, Wi-Fi, NFC, Zigbee, UWB, RFID.

For example, wearable device 101 may broadcast the first information using different short-range wireless communication technologies simultaneously. For example, the wearable device 101 may broadcast the first information using at least two of bluetooth, Wi-Fi, NFC, Zigbee, UWB, RFID technologies simultaneously. It is to be appreciated that wearable device 101 may broadcast the first information at different times using different short-range wireless communication technologies. For example, the wearable device 101 may broadcast the first information using bluetooth technology and then broadcast the first information using RFID technology. The wearable device 101 broadcasts the first information using different near field communication technologies, which may improve the ability of the terminal device 301 near the wearable device 101 to receive the first information.

Optionally, wearable device 101 may continuously broadcast the first information for a first time.

Optionally, the first time may be preset, for example, 10s, 20s, 60s, 120s, 240s, and the like, and the embodiment of the present application does not specifically limit the value of the first time.

It can be understood that, in an actual application scenario, there is a possibility that the terminal device 301 around the wearable device 101 does not receive the first information, or the holder of the terminal device 301 does not agree with the request for communication assistance in the first information, and the wearable device 101 may increase the probability that the terminal device 301 around receives the first information and increase the number of terminal devices 301 receiving the first information by continuously broadcasting the first information, thereby increasing the probability that the wearable device 101 and the terminal device 301 construct a communication link.

As another example, wearable device 101 may periodically broadcast the first information for a first time. With this arrangement, a similar advantageous effect can be achieved as when the wearable device 101 continuously broadcasts the first information in the first time.

Alternatively, the wearable device 101 may continuously broadcast the first information before receiving the response information transmitted by the terminal device 301. The wearable device 101 may also periodically broadcast the first information before receiving the response information sent by the terminal device 301. With this arrangement, a similar advantageous effect can be achieved as when the wearable device 101 continuously broadcasts the first information in the first time.

Step 502, after receiving the first information, the terminal device 301 sends response information to the wearable device 101.

It is understood that after the terminal device 301 receives the first information, if the user of the terminal device 301 agrees to the assistance request in the first information, the terminal device 301 may send a response message to the wearable device 101; if the user of the terminal device 301 does not agree, the terminal device 301 does not send the response message.

In step 503, the wearable device 101 sends second information in response to the response message, where the second information includes help content information and contact information.

For example, the contact information and the help content information in the second information can be seen in table 1.

TABLE 1

It should be understood that the help content information may include the user's name, the user's address, the content of the emergency security event that occurred, the time at which the emergency security event occurred, the geographic location information at which the emergency security event occurred, etc. Wherein, part of the information of the help content information can be stored or set in advance, and part of the information needs to be generated after the emergency safety event is detected.

For example, the user address in the help content information may be pre-stored. The content of the emergency event occurring in the help content information, the time of the emergency event occurring, the geographic location information of the emergency event occurring, and the like may be generated after the wearable device 101 detects the emergency event. The content of the emergency event may be, among other things, the type of the particular emergency event, such as a fall, too fast a heart rate, too slow a heart rate, too low a blood pressure, too low a blood sugar, etc. In a possible embodiment, the wearable device 101 may pre-store a template corresponding to the emergency security event, and after the wearable device 101 detects the emergency security event, the corresponding template may be selected as the content of the emergency security event that occurs according to the emergency security event that occurs. For example, the emergency event is a user falling, and the corresponding templates are: xx (user name) falls; for example, the emergency safety event is a user's hypoglycemia, and the corresponding templates are: xx hypoglycemia. As another example, the corresponding template may be: xx (user name) at xx (time), xx (emergency safety event) occurs at xx (location information of wearable device 101), and emergency assistance is needed.

In step 504, after receiving the second information, the terminal device 301 sends the second information to the target device 102.

It is to be understood that after the terminal device 301 receives the second information, the terminal device 301 may access the network to transmit the second information to the target device 102. For example, the terminal device 301 accessing the network may be accessing a mobile network through a mobile communication technology. For example, the terminal device 301 may access the mobile network through the base station 201 through 4G or 5G technology. For another example, the terminal device 301 may also send the second information to the target device 102 via a Wi-Fi access network.

According to the emergency communication method provided by the embodiment of the application, under the condition that the wearable device 101 cannot send help seeking information through the network and the pairing device 202, whether at least one terminal device 301 existing around agrees to assist in sending the help seeking information can be actively inquired through broadcasting the first information, response information is sent to the wearable device 101 after the terminal device 301 agrees, therefore, the wearable device 101 can determine the address of the terminal device 301 agreeing to send the help seeking information, second information is sent to the terminal device 301, further, the wearable device 101 can establish an emergency communication link through interaction with the terminal device 301, the help seeking information is sent in time, and it is ensured that a user can be timely helped after encountering an emergency safety event.

Optionally, after the wearable device 101 sends the second information in response to the response information in step 503, the method may further include:

in step 505, when the wearable device 101 and the target device 102 are connected, the wearable device 101 stops broadcasting the first information.

Optionally, after the wearable device 101 sends the second information, the step of broadcasting the first information is re-entered. Through this mode of setting up, can increase the probability that terminal equipment 301 received first information around to and increase the quantity of the terminal equipment 301 of receiving first information, improve the probability or the number of times that wearable equipment 101 sent the second information, and then increase wearable equipment 101 and send the success rate of seeking help information.

It is to be understood that the wearable device 101 may be paired with multiple devices, whereby the target device 102 may be paired with the wearable device 101. When the target device 102 is present near the wearable device 101, the target device 102 may automatically connect with the wearable device 101, so that the wearable device 101 may sense whether the second information has been successfully delivered to the target device 102 by whether the target device 102 is connected or not, and further, when the target device 102 is connected with the wearable device 101, the wearable device 101 does not need to send the first information or the second information.

In the embodiment shown in fig. 5, the sending, by the terminal device 301 in step 502, response information, which requires the terminal device 301 to approve the assistance request in the first information, and the sending, by the terminal device 301 in step 502, response information to the wearable device 101 may include:

in step 502-1, the terminal device 301 sends response information to the wearable device 101 in response to the operation instruction that the user of the terminal device 301 chooses to approve assistance.

It should be understood that there may be a plurality of ways for the terminal device 301 to trigger the operation instruction for the user of the terminal device 301 to opt-in to assist, one way being: the terminal device 301 directly sends out the reminder after receiving the first information, and the user of the terminal device 301 can respond to the reminder sent out by the terminal device 301 to implement the operation instruction of whether to agree with the assistance. The other mode is as follows: after receiving the first information, the terminal device 301 does not send a prompt, but determines whether the terminal device 301 starts a response function before receiving the first information, and if the response function is started, which is equivalent to that the user selects to approve assistance, the terminal device 301 can directly send the response information; if the response function is not started, the terminal device 301 sends a prompt, and the user of the terminal device 301 responds to the prompt sent by the terminal device 301 to implement an operation instruction of whether to approve assistance.

It is understood that the response function is a communication assistance function set by the terminal device 301 for other devices, and the terminal device 301 turns on the function, i.e. agrees by default to send information to other devices, i.e. the terminal device 301 sends back the response information directly after receiving the first information.

In the embodiment of the present application, the response function may also be referred to as a communication sharing function. Referring to fig. 8, the embodiment shown in fig. 8 exemplarily illustrates specific steps of the terminal device 301 sending the response information by taking the communication sharing function as an example. As shown in fig. 8, in the embodiment shown in fig. 5, step 502 may include:

step 801, when the terminal device 301 starts the communication sharing function, after the terminal device 301 receives the first information, the terminal device 301 directly sends response information to the wearable device 101.

The manner in which the terminal apparatus 101 sets the communication sharing function is exemplarily described taking the terminal apparatus 301 as a handset. The terminal device 301 may start the communication sharing function before receiving the first information, referring to fig. 9, a user of the terminal device 301 may set an interface of the terminal device 301, and further start the communication sharing function, at this time, the terminal device 301 may provide the communication sharing function for other devices.

As another example, the terminal device 301 may set a corresponding communication sharing function for a specific emergency safety event. Taking a user fall as an example for illustration, referring to fig. 10, a setting interface of the terminal device 301 may display a "fall emergency help" control item, and when the user of the terminal device 301 starts the fall emergency help function, a "fall emergency help" control item is displayed below to display "the communication sharing function can be provided now".

It can be understood that the terminal device 301 may further set a control entry corresponding to another emergency safety event, for example, a "heart rate emergency help" control entry, a "blood pressure emergency help" control entry, a "blood sugar emergency help" control entry, and the like.

It is understood that when the terminal device 301 does not turn on the communication function, the terminal device 301 may not send the response message after receiving the first message. Taking the terminal device 301 as a mobile phone as an example, referring to fig. 11, the setting interface of the terminal device 301 does not start the communication sharing function.

Referring to fig. 12, in the embodiment shown in fig. 5, step 502 may further include:

step 1201, when the terminal device 301 does not start the communication sharing function, after the terminal device 301 receives the first information, the terminal device 301 sends a reminder.

Alternatively, the manner of sending the reminder by the terminal device 301 may be at least one of sound, vibration, pushing information, and lighting a screen, wherein the sound includes voice, ring tone, buzzing sound, and other various types of alert sounds. For example, the terminal device 301 may specifically send the reminder by one or a combination of two or more of voice broadcast, ringing, sending a buzzer, vibrating, pushing information, and lighting a screen.

In step 1202, the terminal device 301 obtains an operation instruction for the user of the terminal device 301 to select to agree to assistance in response to the reminder.

It should be understood that, depending on the manner in which the terminal device 301 issues the alert, the terminal device 301 may implement the operation instruction for selecting the communication assistance in various manners, and thus there are various manners in which the terminal device 301 obtains the operation instruction for the user of the terminal device 301 to select the assistance approval.

Taking the terminal device 301 as a mobile phone as an example, and the emergency safe time as an application scenario of a fall, an example is as follows.

Mode A: if the terminal device 301 is in the screen-locked state, vibration or sound reminding may be selected, for example, after the terminal device 301 receives the first information, the "nearby person falls and provides assistance" may be broadcasted by voice, or different reminding manners may be combined, for example, voice broadcasting is performed while vibrating, or ringing is performed while vibrating, and then the user of the terminal device 301 may implement an operation instruction of selecting assistance approval to the terminal device 301 by means of a voice instruction, for example, the user of the terminal device 301 may send a voice instruction "approve assistance" to the terminal device 301, and after receiving the voice instruction sent by the user, the terminal device 301 sends response information.

For example, after the terminal device 301 issues the alert, it may automatically enter a state of receiving the voice instruction, and at this time, the terminal device 301 displays the interface shown in fig. 13, and when the user of the terminal device 301 issues the voice instruction "agree to assist", the terminal device 301 may recognize the voice instruction and execute the voice instruction. As another example, after the terminal device 301 recognizes the voice command issued by the user, the voice command issued by the user may be displayed in a text and/or sound manner, so that the user of the terminal device 301 can determine whether the terminal device 301 correctly recognizes the voice command.

Mode B: the terminal device 301 may also select a manner of pushing information to remind the user, or combine the manner of pushing information with other manners of reminding, for example, pushing information while vibrating, pushing information while voice broadcasting, and the user of the terminal device 301 may implement an operation instruction of agreeing to assist by selecting in a touch or sliding manner according to the pushed information, and then the terminal device 301 may obtain the operation instruction of agreeing to assist by selecting through the touch operation of the user of the terminal device 310.

Referring to an interface I1 in fig. 14, at this time, the terminal device 301 lights up in a screen-off state, and then displays the push information "there is a device requesting assistance in the vicinity, and clicks on the view details" on the screen-lock interface of the terminal device 301. After the terminal device 301 is unlocked, referring to an interface I2 in fig. 14, the display interface of the terminal device 301 displays at least two control items, one of which is "consent", that is, the user of the terminal device 301 can manually select consent assistance; another control entry is "ignore", i.e. the user of the terminal device 301 may manually select not to agree to assistance. As another example, the user may also select a control item displaying "consent" by way of a gesture operation.

Mode C: the user may implement an operation instruction for selecting an agreement to assist by changing the state of the terminal device 301 in a manner of reminding at least one of vibration, sound, display options, and a lighting screen of the terminal device 301.

For example, after the terminal device 301 sends a reminder, the user of the terminal device 301 may indicate agreement with assistance by rotating the terminal device 301, indicate disagreement with assistance by swinging the terminal device 301, and the terminal device 301 may sense the gesture of the terminal device 301 through a sensor, such as a gyroscope, to recognize that the user of the terminal device 301 rotates or swings the terminal device 301, thereby obtaining an operation instruction that the user of the terminal device 301 selects agreement with assistance.

It should be noted that the user of the terminal device 301 may implement an operation instruction for selectively agreeing to assist through at least one of the mode a, the mode B, and the mode C.

In step 1203, the terminal device 301 sends response information to the wearable device 101 in response to the operation instruction that the user of the terminal device 301 chooses to approve assistance.

It can be understood that, after receiving the second information, the terminal device 301 may obtain the content of the second information, and then the terminal device 301 may directly send the help content information to the target device 102, however, this approach may not only increase the burden of the user of the terminal device 301, but also has a security problem. In view of this, the present application improves communication security by the embodiment shown in fig. 15, and avoids increasing the burden on the user of the terminal device 301.

The embodiments shown in fig. 5 to 14 further include a server 402, wherein the embodiment shown in fig. 8 is taken as an example for illustration. As shown in fig. 15, after the terminal device 301 in step 504 receives the second information and transmits the second information to the target device 102, the method may include:

in step 1501, the terminal device 301 transmits the second information to the server 402.

In step 1502, the server 402 sends the help content information to the target device 102 according to the contact information.

According to the emergency communication method provided by the embodiment of the application, the terminal device 301 sends the second information to the server 402, and the server 402 sends the second information to the target device 102, so that on one hand, the burden of the user of the terminal device 301 can be avoided from being increased, for example, a contact person can be prevented from receiving help content information and repeatedly communicating with the user of the terminal device 301 to inquire about the specific situation of the user of the wearable device 101; on the other hand, avoiding the user of the terminal device 101 from communicating with the contact person may also avoid transmitting wrong information, which may erroneously convey the physical state of the user of the wearable device 101 because the user of the terminal device 101 may not have medical expertise; on the other hand, the security and privacy of communication can be improved, the contact information or the information of the user of the terminal device 301 can be prevented from being exposed by sending the second information through the server 402, and the terminal device 301 can be prevented from maliciously modifying the help content information.

It should be understood that the embodiment shown in fig. 15 is directed to a security problem between the terminal device 301 and the target device 102, and a communication security problem between the wearable device 101 and the terminal device 301 also needs to be considered, and further, in the embodiments shown in fig. 5 to fig. 15, the second information may be encrypted by using a key, which is exemplified by the embodiment shown in fig. 15, referring to fig. 16, the wearable device 101 may store a key in advance, and the wearable device 101 of step 503 may send the second information in response to the response information, and may include:

at step 1601, wearable device 101 encrypts the second information with the key in response to the response information.

At step 1602, the wearable device 101 sends the encrypted second information.

Alternatively, the key pre-stored by wearable device 101 may be a symmetric key or an asymmetric key pair. Correspondingly, the wearable device 101 may encrypt the second information in a symmetric encryption manner, or the wearable device 101 may encrypt the second information in an asymmetric encryption manner.

Optionally, the server 402 stores a digital certificate corresponding to the key of the wearable device 101 in advance, and the step 1502 of sending the help content information to the target device 102 according to the contact information may include:

in step 1603, the server 402 uses the digital certificate to parse the encrypted second information to obtain the contact information and the help content information in the second information.

The server 402 sends 1604 the help content information to the target device 102.

It can be understood that, after the server 402 receives the second information, it may verify whether the encrypted second information is tampered with by using a pre-stored digital certificate, so as to prevent the terminal device 301 from transmitting the false second information.

The process of encrypting the second information by the wearable device 101 and parsing the second information by the server 402 is exemplarily illustrated in asymmetric encryption as follows:

step a, the wearable device 101 may perform hash calculation on the second information to obtain a message digest (hash value), which may ensure that the process is irreversible, i.e., the information content cannot be calculated through the message digest, and then the message digest is not repeated, i.e., if the content of the second information is changed, the message digest obtained through hash calculation again is not the same as the message digest before the change;

step B, the wearable device 101 encrypts the message digest by using a private key in the secret key, and the encrypted result can be called a digital signature;

step C, the wearable device 101 sends the encrypted second information, that is, the digital signature and the content of the second information to the terminal device 301;

step D, the server 402 may decrypt the data signature in the received second information by using the public key of the corresponding private key in the digital certificate, to obtain a decrypted message digest;

step E, the server 402 performs hash calculation on the content of the received second message to obtain a calculated message digest;

step F, the server 402 compares the decrypted message digest with the calculated message digest, and if the decrypted message digest is the same as the calculated message digest, it indicates that the content of the second information has not been tampered.

It should be noted that, the above asymmetric encryption and decryption implementation may be combined with an authoritative digital certificate issued by an authoritative institution, so as to further increase security. The authoritative digital certificate may include: a public key in the secret key and a digital signature corresponding to the public key. In the above process, step C may send the authoritative digital certificate, the digital signature, and the content of the second information to the terminal device 301, and since the public key of the authoritative digital certificate is publicly available, the server 402 may verify the public key of the key in the authoritative number by using the public key of the authoritative digital certificate, and then perform steps D to F by using the verified public key.

Alternatively, the key stored in advance by the wearable device 101 may be a key preset at the time of factory shipment of the wearable device 101.

Alternatively, the key pre-stored by wearable device 101 may be configured by server 402.

For example, the pairing device 202 may connect with the server 402, and may obtain the key from the server 402, and the key may be configured into the wearable device 101 when the pairing device 202 connects with the wearable device 101.

Referring to fig. 17, in the communication process between the wearable device 101 and the terminal device 301, the terminal device 301 may verify the validity of the wearable device 101 for sending the first information, which is described by taking the embodiment shown in fig. 16 as an example, as shown in fig. 17, the broadcasting the first information when the wearable device 101 cannot be connected to the pairing device 202 in step 501 may include:

in step 1701, when the wearable device 101 cannot connect to the pairing device 202, the wearable device 101 encrypts the first information using the key.

Optionally, step 1601 may include:

step 1701-1, when the wearable device 101 triggers sending help information and the wearable device 101 cannot be connected with the pairing device 202, the wearable device 101 encrypts the first information by using the key.

At step 1702, wearable device 101 broadcasts the encrypted first information.

As shown in fig. 17, in the embodiment shown in fig. 15 of the present application, the terminal device 301 stores a digital certificate corresponding to a key in advance, and after the terminal device 301 receives the first information, the method further includes:

in step 1703, terminal device 301 verifies whether the first information is legal using the digital certificate.

Step 1704, when the terminal device 301 determines that the first information is legal, the step of sending response information to the wearable device 101 is entered.

For example, after the terminal device 301 executes step 1704, step 801 or step 1201 may be entered.

It can be understood that the encryption mode of the first information and the mode of verifying the encrypted first information of the terminal device 301 may refer to steps a to F.

According to the emergency communication method provided by the embodiment of the application, the terminal device 301 can verify the validity of the first information broadcast by the wearable device 101 through the pre-stored digital certificate, so that on one hand, a third-party malicious device can be prevented from intercepting the first information, and the content of the first information is tampered; on the other hand, the terminal device 301 can be prevented from being attacked by illegal information.

Note that the digital certificate stored in advance in the terminal device 301 may be preset when the terminal device 301 is shipped from a factory. Alternatively, the terminal device 301 and the wearable device 101 are the same platform, for example, the terminal device 301 registers with the server 402, obtains the digital certificate sent by the server 402, and the terminal device 301 may store the digital certificate for use in verifying the first information.

It should be understood that the terminal device 301 may also verify the validity of the second information using the digital certificate in step 1501.

In order to further increase the security of the terminal device 301, and avoid receiving a large amount of malicious information after the terminal device 301 agrees to assist, and may limit the behavior of the terminal device 301 sending the response information, in any of the embodiments shown in fig. 5 to fig. 17 of the present application, before the terminal device 301 sends the response information to the wearable device 101, the method further includes:

step 1801, when the amount of the history information that has been currently sent by the terminal device 301 is smaller than the first threshold, the step of sending response information to the wearable device 101 by the terminal device 301 is entered.

It should be understood that the history information is information that the terminal device 301 has transmitted in response to the historical assistance request. For example, the history information may be response information that the terminal device 301 has transmitted in response to the first information in the history; as another example, the history information may be second information that the terminal device 301 has transmitted in response to the first information in history.

Alternatively, the first threshold may be a value of 5, 10, 20, or more, and the application does not limit the specific value of the first threshold.

Taking the first threshold as 5 and the historical information as the already sent response information as an example, if the number of the response information currently sent by the terminal device 301 is 4 and is smaller than the first threshold, the terminal device 301 enters a step of sending response information to the wearable device 101; if the number of response messages that have been currently sent by the terminal device 301 is 5, which is equal to the first threshold, the terminal device 301 does not send response messages.

Optionally, in the embodiment shown in fig. 17 of the present application, step 1801 may precede step 1703, see fig. 18. With this setting, if the history information that the terminal device 301 has currently transmitted is greater than or equal to the first threshold, step 1703 may not be performed. Alternatively, step 1801 may be after step 1703. With this setting, if the terminal device 301 verifies that the first information is not legitimate, step 1801 may not be performed. Alternatively, after step 1801, the terminal device 301 may also directly enter step 801 or step 1201, so that a plurality of other embodiments may be obtained based on the embodiment shown in fig. 17.

Optionally, step 1801 is executed after the terminal device 301 of step 502-1 or step 1203 responds to the operation instruction of agreeing to assist selected by the user of the terminal device 301.

in step 1901, when the total flow of the history information that has been currently sent by the terminal device 301 is smaller than the second threshold, the step of sending the response information to the wearable device 101 by the terminal device 301 is entered.

Optionally, the second threshold may be 512KB, 1MB, 2MB, 5MB, and the like, and the embodiment of the present application does not limit the specific value of the second threshold.

Taking the second threshold as 5MB and the history information as the already sent second information as an example, if the total flow of the second information that has been currently sent by the terminal device 301 is 4MB and is smaller than the second threshold, the terminal device 301 proceeds to the step of sending response information to the wearable device 101; if the total flow of the second information that has been currently transmitted by the terminal device 301 is 5MB and is greater than the second threshold, the terminal device 301 does not transmit the response information.

It is understood that step 1801 and step 1901 function similarly and may be interchanged. Step 1901 may precede step 1703, see fig. 19, for example. With this setting, if the history information that the terminal device 301 has currently transmitted is greater than or equal to the first threshold, step 1703 may not be performed. Alternatively, step 1901 may be after step 1703. With this setting, if the terminal device 301 verifies that the first information is not legitimate, step 1901 may not be performed. Alternatively, after step 1901, terminal apparatus 301 may also directly proceed to step 801 or step 1201.

Alternatively, step 1901 is executed after the terminal device 301 of step 502-1 or step 1203 responds to the operation instruction of agreeing to assistance by the user selection of the terminal device 301.

According to the emergency communication method provided by the embodiment of the application, the terminal device 301 may determine whether to send the response information according to the amount or the total flow of the historical information that has been currently sent, so that the terminal device 301 may be prevented from sending information for multiple times due to receiving a malicious request, and further, a large amount of flow is prevented from being consumed.

step 1902, when the data amount of the second information received by the terminal device 301 is smaller than the third threshold, the step of sending the second information by the terminal device 301 is entered.

Optionally, the third threshold may be 512KB, 1MB, 2MB, 5MB, and the like, and the embodiment of the present application does not limit the specific value of the third threshold.

According to the emergency communication method provided by the embodiment of the application, after the terminal device 301 receives the second information, the data volume of the second information is judged, and if the second information is too large, the second information can be regarded as malicious information, so that the security of the terminal device 301 is improved. It can be understood that the second information includes the help content information and the contact information, and is usually text information, and may not include pictures, so the size of the second information is limited, and usually does not exceed 1MB, and if the size of the second information exceeds 1MB, it can be considered that the second information sent at this time is added with other information, which may cause a security problem.

In the above embodiment, the help content information of the second information may include the location information of the wearable device 101, and then the contact may accurately know the location of the user of the wearable device 101 where the emergency safety event occurs through the location information in the target device 102, so as to facilitate the user of the wearable device 101 to obtain help, so in the embodiment shown in fig. 5 to 19, before the wearable device 101 in step 503 sends the second information in response to the response information, or before the wearable device 101 in step 1601 encrypts the second information in response to the response information, the method further includes:

In the above embodiment, if the wearable device 101 does not support the positioning function, considering that the terminal device 301 is located near the wearable device 101, the wearable device 101 may request the terminal device 301 to send the current positioning information of the terminal device 301 to the target device 102, and the effect of indicating the position of the wearable device 101 may also be achieved. Thus, in the embodiments shown in fig. 5 to fig. 19, the first information or the second information sent by the wearable device 101 may include positioning assistance request information, and the positioning assistance request information may be used for the wearable device 101 to request current positioning information of the terminal device 301.

the terminal device 301 sends the second information and the current positioning information of the terminal device 301 to the target device 102.

It should be noted that, when the second information includes the positioning assistance request information, the terminal device 301 may send a prompt to prompt the user of the terminal device 301 after receiving the second information, the second information also includes the positioning assistance request, and the terminal device 301 may send the second information and the current positioning information of the terminal device 301 in response to an operation instruction that the user of the terminal device 301 agrees to select.

Alternatively, the terminal device 301 may also refuse to transmit the current location information of the terminal device 301 in response to the user of the terminal device 301 selecting a disagreeable operation instruction, at which time the terminal device 301 may select to transmit only the second information.
