TECHNICAL FIELD

This application relates to the field of terminal technologies, and in particular, to a distress information sending method and system.

BACKGROUND

When encountering disasters and danger (such as accidents during outdoor sports, natural disasters such as earthquakes and typhoons, ship damages during an ocean travel, or animals attacking during field scientific research), people can call for help from the outside world through mobile phones as soon as possible.

In the process of calling for help by using the mobile phones, most users call for help by using a cellular network of the mobile phones, for example, a user makes a distress call to the outside world by using the cellular network. When locations of the users are not covered by a cellular network, the users usually have to give up calling for help by using the mobile phones. As a result, the users are not to be rescued in time.

SUMMARY

In view of this, the application provides a distress information sending method and system, to enable a user to be rescued in time by setting automatic switching of various communication means.

According to a first aspect, this application provides a sending distress information method, and the method includes: A terminal device obtains first distress information, where the first distress information includes at least one of adverse sign information or positioning information of a user. The terminal device selects a first communication network from a plurality of communication networks in a preset sequence, where the first communication network is any one of a short-range connection network, a cellular network, a satellite network, and a communication network between remote devices, and the communication network between remote devices is a point-to-point communication network established by the terminal device and a rescue processing device by using a preset frequency resource. When the terminal device can be connected to the rescue processing device by using the first communication network, the terminal device sends the first distress information to the rescue processing device by using the first communication network. Alternatively, when the terminal device cannot be connected to the rescue processing device by using the first communication network, the terminal device re-selects a new first communication network from the plurality of communication networks in the preset sequence.

In the solution of this application, the communication network can be automatically switched in the preset sequence, so that a network capable of sending the first distress information can be selected from the plurality of communication networks, so that the user can be rescued in time.

In a possible implementation, before that a terminal device obtains first distress information, the method further includes: The terminal device receives first pre-distress information sent from a wearable smart device, where the first pre-distress information is generated based on adverse sign information when the wearable smart device detects an abnormality in a sign of the user; and that a terminal device obtains first distress information includes: The terminal device generates the first distress information based on the first pre-distress information.

In the solution of this application, the adverse sign information of the user is detected by the wearable smart device, so that a current physical state of the user can be obtained. Therefore, accurate reference information can be provided for subsequent rescue.

In a possible implementation, that the terminal device generates the first distress information based on the first pre-distress information includes: The terminal device sorts distress content in the first pre-distress information based on an importance degree; and processes distress content corresponding to a sequence number before a preset threshold, to obtain the first distress information.

In the solution of this application, the distress content in the first pre-distress information is sorted based on an importance degree. This can facilitate a rescue team to quickly identify important information in the first pre-distress information after receiving the first pre-distress information. Generally, after receiving the first pre-distress information, it is necessary to perform information analysis on the first pre-distress information, but in this application, there is no need to perform information analysis on the first pre-distress information. This can greatly reduce time consumption caused by the information analysis, and therefore improves rescue efficiency.

In a possible implementation, the preset sequence from front to back is: the short-range connection network, the cellular network, the satellite network, and the communication network between remote devices.

Usually, use costs of a short-range connection module, a cellular communication module, and a satellite communication module increase in sequence, and a module for communication between remote devices requires that two devices turn on this function at the same time to implement communication. This is difficult to use. Therefore, a communication manner in which communication is performed by using the short-range connection module first, and when communication fails, communication is performed by using the cellular communication module, the satellite communication module, and the module for communication between remote devices in sequence. This can reduce use costs, and ensure smooth sending of distress information as much as possible, so that a distressed person can be rescued in time.

In a possible implementation, that the terminal device selects a first communication network from a plurality of communication networks in a preset sequence, and when the terminal device can be connected to the rescue processing device by using the first communication network, the terminal device sends the first distress information to the rescue processing device by using the first communication network; or when the terminal device cannot be connected to the rescue processing device by using the first communication network, the terminal device re-selects a new first communication network from the plurality of communication networks in the preset sequence includes: The terminal device selects the short-range connection network as the first communication network from the plurality of communication networks in the preset sequence, and determines whether the terminal device can be connected to the rescue processing device by using the short-range connection network. When the terminal device can be connected to the rescue processing device by using the short-range connection network, the terminal device sends the first distress information to the rescue processing device by using the short-range connection network. Alternatively, when the terminal device cannot be connected to the rescue processing device by using the short-range connection network, the terminal device selects the cellular network as the first communication network, and determines whether the terminal device can be connected to the rescue processing device by using the cellular network. When the terminal device can be connected to the rescue processing device by using the cellular network, the terminal device sends the first distress information to the rescue processing device by using the cellular network. Alternatively, when the terminal device cannot be connected to the rescue processing device by using the cellular network, the terminal device selects the satellite network as the first communication network, and determines whether the terminal device can be connected to the rescue processing device by using the satellite network. When the terminal device can be connected to the rescue processing device by using the satellite network, the terminal device sends the first distress information to the rescue processing device by using the satellite network. Alternatively, when the terminal device cannot be connected to the rescue processing device by using the satellite network, the terminal device selects the communication network between remote devices as the first communication network, and determines whether the terminal device can be connected to the rescue processing device by using the communication network between remote devices. When the terminal device can be connected to the rescue processing device by using the communication network between remote devices, the terminal device sends the first distress information to the rescue processing device by using the communication network between remote devices. Alternatively, when the terminal device cannot be connected to the rescue processing device by using the communication network between remote devices, the terminal device re-selects a new first communication network in the preset sequence.

In a possible implementation, the determining whether the terminal device can be connected to the rescue processing device by using the communication network between remote devices includes: The terminal device initiates scanning of a communication signal between the remote devices, and when the communication signal between the remote devices is obtained through scanning, the terminal device establishes a connection with a peer device that sends the communication signal between the remote devices. The terminal device sends an inquiry instruction to the peer device, where the inquiry instruction is used for inquiring whether the peer device can be connected to the rescue processing device, and the inquiry instruction includes an address of the rescue processing device. In response to an inquiry result sent by the peer device, when the peer device can be connected to the rescue processing device, the terminal device determines that the terminal device can be connected to the rescue processing device by using the communication network between remote devices, or when the peer device cannot be connected to the rescue processing device, the terminal device determines that the terminal device cannot be connected to the rescue processing device by using the communication network between remote devices.

In a possible implementation, the determining whether the terminal device can be connected to the rescue processing device by using the cellular network includes: The terminal device determines whether the terminal device can be connected to the rescue processing device by using a subscriber identity identification SIM card operator cellular network in the cellular network. When the terminal device can be connected to the rescue processing device by using the SIM card operator cellular network in the cellular network, the terminal device determines that the first communication network is the SIM card operator cellular network in the cellular network. Alternatively, when the terminal device cannot be connected to the rescue processing device by using the SIM card operator cellular network in the cellular network, the terminal device determines whether the terminal device can be connected to the rescue processing device by using a non-SIM card operator cellular network in the cellular network. When the terminal device can be connected to the rescue processing device by using a non-SIM card operator cellular network in the cellular network, the terminal device determines that the first communication network is the non-SIM card operator cellular network in the cellular network. Alternatively, the method further includes: When the terminal device cannot be connected to the rescue processing device by using a non-SIM card operator cellular network in the cellular network, the terminal device determines whether the terminal device can be connected to the rescue processing device by using the satellite network.

In a possible implementation, the method further includes: The terminal device receives second pre-distress information sent from the wearable smart device, where the second pre-distress information is generated based on changed sign information when the wearable smart device detects that sign information of the user is inconsistent with the adverse sign information in the first pre-distress information. The terminal device generates second distress information based on the second pre-distress information and sends the second distress information to the rescue processing device.

In a possible implementation, the method further includes: The terminal device receives third pre-distress information sent from the wearable smart device, where the third pre-distress information is generated based on changed positioning information when the wearable smart device detects that positioning information of the user is inconsistent with the positioning information in the first pre-distress information. The terminal device generates third distress information based on the third pre-distress information and sends the third distress information to the rescue processing device. Alternatively, when the terminal device detects that positioning information of the user is inconsistent with the positioning information in the first distress information, the terminal device collects the changed positioning information, generates fourth distress information based on the changed positioning information, and sends the fourth distress information to the rescue processing device.

In a possible implementation, the method further includes: The terminal device receives rescue information sent from the rescue processing device. The rescue information is used to indicate the terminal device to establish contact with a rescue team.

In a possible implementation, the rescue information includes rescue time and a communication mode between the rescue team and the user. After the terminal device receives the rescue information sent from the rescue processing device, the method further includes: The terminal device establishes, based on the communication mode between the rescue team and the user, a connection with the rescue team when the rescue time arrives.

In the solution of this application, the rescue time in the rescue information can be used to remind the user to make preparations in advance before arrival of the rescue time, to facilitate timely rescue.

DESCRIPTION OF EMBODIMENTS

Technical solutions in embodiments of this application are described below with reference to the accompanying drawings in the embodiments of this application. In the descriptions of this application, unless otherwise specified, “at least one” means one or more, and “a plurality of” means two or more. In addition, to clearly describe the technical solutions in embodiments of this application, in embodiments of this application, words such as “first” and “second” are used for distinguishing between same items or similar items that have basically same functions or purposes. A person skilled in the art may understand that the words such as “first” and “second” do not limit a quantity or an execution sequence, and the words such as “first” and “second” do not indicate a definite difference.

With development of electronic and communication technologies, portable terminals have become necessities of modern life, and with development of terminal technologies, functions of the portable terminals are more diversified. For example, a portable communication terminal can be used as a personal digital assistant in addition to being able to perform communication. Moreover, a portable terminal can also be configured in a multimedia center, to provide a user with all-round leisure services from listening to music, receiving multimedia digital broadcasts, watching movies to running various games. In addition, the portable terminal also integrates a function of a digital camera, and can take a picture and record a video.

Therefore, people are increasingly dependent on portable terminals. When users encounter natural disasters or man-made disasters, people usually choose to call for help to the outside world as soon as possible by using the portable terminal that is an electronic device carried at all times. The natural disasters are abnormal phenomena in nature that human beings depend on, mainly including earthquakes, volcanic eruptions, mudslides, tsunamis, typhoons, floods, and the like. The man-made disasters are disasters caused by human factors, mainly including natural resources exhaustion disasters, environmental pollution disasters, fires, traffic accidents, and the like. Whether it is a natural disaster or man-made disaster, as long as the disaster occurs, the disaster may cause serious consequences.

At present, distress can be spread through various communication means, for example, short-range communication, cellular communication, satellite communication, and communication between remote devices. However, these communication means are relatively independent, and only when a user starts a specific communication means is the corresponding communication means started. For a crisis moment of emergency rescue, the user cannot know what kind of communication means can be used to immediately send out distress information, and can only try one by one. Moreover, this distress mode needs great cooperation from the user. If a situation faced by users is bad, and it is inconvenient for the user to operate or the user has no condition to perform an operation, this distress mode provide no help for the user, and therefore the user miss a best rescue opportunity.

For example. FIG. 1 illustrates a possible distress scenario in which a user 101 conducts a field research expedition in a deep mountain, and in a process of research expedition, accidentally steps on a poisonous snake 102, and was attacked by the poisonous snake 102. Some time after being bitten by the poisonous snake, a smart watch of the user 101 detects that blood pressure of the user 101 begins to decrease, and notifies the user 101 in a form of lighting. After seeing the lighting prompt of the smart watch, the user 101 knows that a sign of the user is abnormal. By looking at the smart watch, it can be seen that the blood pressure drops beyond a normal value. This is life-threatening. Then the user 101 makes a distress call to the outside world by using a mobile phone. Because of weak signal coverage of a base station in deep mountains, the distress call of the user 101 cannot be dialed out. When the user 101 does not find another viable mean of communication, the user may not be able to contact the outside world and thus be unable to be rescued in time.

Therefore, this application provides distress information sending methods and a distress information sending system. By setting automatic switching of various communication means, a user can be rescued in time.

In response to an operation of the user on the personal profile button 604 on the interface 603, the mobile phone may display an interface 605 as shown in (c) in FIG. 6. The interface 605 may include a personal profile interface 606. The personal profile interface 606 includes personal information like a birthday, a gender, an address, a blood type, an emergency contact, and a phone number. The user may refine the personal information in the personal profile interface 606.

For example, in FIG. 7A and FIG. 7B, a distress information sending method provided by an embodiment of this application is described below, including:

701: A wearable smart device detects an abnormality in a sign of a user, collects adverse information, and obtains user positioning information; and generates first pre-distress information based on the adverse information, the user positioning information, and pre-stored user personal information, and sends the first pre-distress information to a short-range connection module of a mobile phone.

With reference to FIG. 1, the user 101 conducts the field research expedition in the deep mountain. When the user 101 is accidentally bitten by the poisonous snake 102, the wearable smart device can detect a blood pressure drop of the user 101. When a blood pressure drop exceeds a preset threshold, the wearable smart device considers that the user 101 currently has an adverse sign and collects adverse sign information including the blood pressure drop.

The wearable smart device automatically sends the first pre-distress information to the short-range connection module of the mobile phone. The first pre-distress information may include the adverse sign information (for example, a blood pressure drop value). In some embodiments, the first pre-distress information further includes at least one of positioning information and personal information. The personal information may be input by the user in the wearable smart device in advance.

Alternatively, when the user 101 perceives that the user is currently in a disaster environment (for example, being bitten by the poisonous snake), the user may manually input the first pre-distress information including the adverse information, the positioning information, and the personal information into the wearable smart device. After receiving the first pre-distress information input by the user, the wearable smart device sends the first pre-distress information to the short-range connection module (the mobile phone and the wearable smart device have a communication connection through the short-range connection module) of the mobile phone.

For example, as shown in FIG. 8, when a user encounters a disaster, the user may add first pre-distress information including personal information, emergency information, and custom information of the user to a rescue function in the Sports and health APP of a wearable smart device 801. The custom information may also be chosen to add any one or more of a text, a picture, and a video. Then the wearable smart device 801 sends the obtained first pre-distress information to a mobile phone 802. For example, the wearable smart device 801 may send the obtained first pre-distress information to the mobile phone 802 through a short-range connection module. Subsequently, the wearable smart device 801 may also perform other information exchange with the mobile phone 802 through the short-range connection module during a working process. This is not limited in embodiments of this application. In addition, the Sports and health APP can also be referred to as a Health APP, a Health assistant APP, and the like. This is not limited in embodiments of this application.

Alternatively, when the user 101 perceives that the user is currently in a disaster environment (for example, being bitten by the poisonous snake), the user may press a one-touch rescue function of the wearable smart device, and after receiving a press operation of the user, the wearable smart device sends the first pre-distress information to the short-range connection module of the mobile phone.

Alternatively, the mobile phone is provided with a sensor configured to monitor user sign information. When a change of the user sign information is detected, the sensor may directly send the user sign information to a processing module. The sensor configured to monitor user sign information may include a blood oxygen and heart rate sensing sensor, an optical sensor, and the like. The blood oxygen and heart rate sensing sensor may be configured to monitor blood oxygen and a heart rate. The optical sensor may be configured to monitor a human body heart rate, blood, and other biological characteristics.

Alternatively, when the user 101 perceives that the user is currently in a disaster environment (for example, being bitten by the poisonous snake), the user may manually input the first pre-distress information including the adverse information, the positioning information, and the personal information into the mobile phone in time, and a user interaction module of the mobile phone sends the first pre-distress information to the processing module after receiving the first pre-distress information input by the user.

In addition, when the user 101 perceives that the user is currently in the disaster environment (for example, being bitten by the poisonous snake), the user may press the one-button rescue function of the mobile phone, and the mobile phone sends a distress request of the user to the processing module after receiving the pressing operation of the user.

For example, the adverse information presented by the user may include a change in blood pressure that does not meet a preset threshold, a drop or rise in a body temperature that does not meet a preset threshold, and a quantity of times of heartbeats that do not meet a preset threshold for a fixed period of time.

The first pre-distress information includes sign information, positioning information, personal information, emergency information, situated environment information and user custom information.

The sign information may include a blood type, blood pressure, blood oxygen content, a heart rate, and the like.

The positioning information may be determined based on global navigation satellite system GNSS position information of the wearable smart device obtained by the wearable smart device, or may be determined based on GNSS position information of the mobile phone obtained by the positioning module of the mobile phone after the wearable smart device sends the first pre-distress information to the mobile phone. The GNSS may include a global positioning system GPS, a global navigation satellite system GLONASS, a Beidou navigation satellite system BDS, a quasi-zenith satellite system QZSS, or a satellite based augmentation system SBAS. The situated environment information includes a picture of a situated environment, a video of the situated environment, and the like.

The personal information may include a gender, an age, a birthday, and an ID number,

The emergency information may include: a home address, an allergic reaction, an emergency contact, an emergency contact phone number, and the like.

The user custom information may include a brief description of a current situation provided by the user, as well as other information that needs to be notified to the rescue processing device.

In some embodiments, the short-range connection module may include a variety of short-range communication components such as a Wi-Fi component, a Bluetooth component, a Zigbee protocol (Zigbee) component, and an infrared component. The mobile phone may communicate with the wearable smart device by using these short-range communication components. For example, the wearable smart device and the mobile phone may be connected directly through Wi-Fi or join a same hotspot device connection.

Alternatively, the wearable smart device may establish a connection with a Bluetooth component in the short-range connection module of the mobile phone through Bluetooth, and then send the first pre-distress information to the mobile phone through Bluetooth.

Alternatively, the wearable smart device establishes a connection with the Zigbee component in the short-range connection module of the mobile phone through Zigbee, and then sends the first pre-distress information to the mobile phone through Zigbee.

A Zigbee technology is a bidirectional wireless communication technology with a short range, low complexity, low power consumption, a low speed, and low costs, and is mainly used for data transmission between various electronic devices at a short distance, with low power consumption, and a low transmission rate.

702: The short-range connection module of the mobile phone sends the first pre-distress information to the processing module of the mobile phone in response to the first pre-distress information sent by the wearable smart device.

After the short-range connection module of the mobile phone receives the first pre-distress information sent by the wearable smart device, because the short-range connection module does not have a data processing capability, the short-range connection module sends the first pre-distress information to the processing module of the mobile phone.

703: After receiving the first pre-distress information, the processing module of the mobile phone generates first distress information based on the first pre-distress information.

After receiving the first pre-distress information, the processing module may extract content of the first pre-distress information, and then supplement the extracted content to a fixed format of the first distress information.

Alternatively, because there are many types of natural disasters, the processing module extracts content of the first pre-distress information, and analyzes the extracted content after extraction. Then, based on an analysis result, the content of the first pre-distress information is sorted based on an importance degree. Information that is sorted at the forefront is marked for processing, and the marked sorting information is used as the first distress information. In this way, after the rescue processing device receives the first distress information, the rescue processing device may quickly determine important information based on the sorting and a mark, and prepare required supplies for a distressed person based on the important information.

For example, with reference to FIG. 1, after the user 101 is bitten by the poisonous snake 102, the wearable smart device sends the first pre-distress information to the mobile phone. The first pre-distress information includes indication information that a current blood pressure drop of the user exceeds a threshold, cause explanation information of the blood pressure drop, and the like. The cause explanation information of the blood pressure drop may be a user custom input field. After receiving the first pre-distress information, the mobile phone may adjust sorting of the indication information that a current blood pressure drop of the user exceeds a threshold and the cause explanation information of the blood pressure drop to the front, and then mark the indication information that a current blood pressure drop of the user exceeds a threshold and the cause explanation information of the blood pressure drop. Finally, the marked sorting information is sent to the rescue processing device as the first distress information. This is convenient for the rescue processing device to process the first distress information in time after receiving the first distress information.

For example, the first distress information may include identity information of a distressed person, location information of the distressed person, physical health data such as a blood type, blood pressure, blood oxygen content, a heart rate, and the like of the distressed person, an emergency contact and contact information set by the distressed person, a photo and a video of the environment in which the distressed person is situated, a text, an image, an audio or a video customized by the distressed person, and the like.

704: The processing module of the mobile phone determines whether the short-range connection module can be connected to the rescue processing device.

The mobile phone may perform a network connection test by invoking a packet Internet groper (Packet Internet Groper, PING) program, and determine whether the short-range connection module can be connected to the rescue processing device based on a network connection test result.

Specifically, The PING sends an Internet control messages protocol (Internet Control Messages Protocol, ICMP) echo request message to the rescue processing device by using a communication network provided by the short-range connection module and reports a desired ICMP echo response. In preset time, when the desired ICMP echo response is received, it is considered that the mobile phone can be connected to the rescue processing device by using the short-range connection module. Alternatively, when the desired ICMP echo response is not received, it is considered that the mobile phone cannot be connected to the rescue processing device by using the short-range connection module.

In some embodiments, the short-range connection module may include a first short-range connection and a second short-range connection module. The first short-range connection module is configured to connect the wearable smart device and the mobile phone, and the second short-range connection module is configured to connect the mobile phone and the rescue processing device.

The second short-range connection module may also include a variety of short-range communication components such as a Wi-Fi component, a Bluetooth component, and a Zigbee component.

The mobile phone may communicate with the wearable smart device by using the first short-range connection module. Specifically, the mobile phone may communicate with the wearable smart device by using the Wi-Fi component in the first short-range connection module, may alternatively communicate with the wearable smart device by using the Bluetooth component in the first short-range connection module, or may communicate with the wearable smart device by using the Zigbee component in the first short-range connection module.

The mobile phone may communicate with the rescue processing device by using the second short-range connection module. Specifically, the mobile phone may communicate with the rescue processing device by using the Wi-Fi component in the second short-range connection module, may alternatively communicate with the rescue processing device by using the Bluetooth component in the second short-range connection module, or may communicate with the rescue processing device by using the Zigbee component in the second short-range connection module.

Components in the second short-range connection module used for communication between the mobile phone and the rescue processing device may be the same as components in the first short-range connection module used for communication between the mobile phone and the wearable smart device. That is, the mobile phone communicates with the rescue processing device by using the Wi-Fi component, and communicates with the wearable smart device by using the Wi-Fi component.

Alternatively, the mobile phone communicates with the rescue processing device by using the Bluetooth component, and communicates with the wearable smart device by using the Bluetooth component.

Alternatively, the mobile phone communicates with the rescue processing device by using the Zigbee component, and communicates with the wearable smart device by using the Zigbee component.

Components in the second short-range connection module used for communication between the mobile phone and the rescue processing device may be different from components in the first short-range connection module used for communication between the mobile phone and the wearable smart device. That is, the mobile phone communicates with the rescue processing device by using the Wi-Fi component, and communicates with the wearable smart device by using the Bluetooth component (or the Zigbee component).

Alternatively, the mobile phone communicates with the rescue processing device by using the Bluetooth component and communicates with the wearable smart device by using the Wi-Fi component (or the Zigbee component).

Alternatively, the mobile phone communicates with the rescue processing device by using the Zigbee component and communicates with the wearable smart device by using the Wi-Fi component (or the Bluetooth component).

In some other embodiments, the short-range connection module may include a variety of short-range communication components such as a Wi-Fi component, a Bluetooth component, and a Zigbee component, and the mobile phone may communicate with the wearable smart device and the rescue processing device separately by using short-range communication components in the short-range communication module.

Specifically, a short-range communication component in the short-range connection module used for communication between the mobile phone and the wearable smart device and a short-range communication component in the short-range connection module used for communication between the mobile phone and the rescue processing device may be the same or different.

705A: After determining that the short-range connection module can be connected to the rescue processing device, the processing module of the mobile phone sends a first request to the short-range connection module, where the first request includes the first distress information.

The first request is used for requesting to send the first distress information to the rescue processing device.

For example, the processing module may send the first request to the short-range connection module. With reference to 704, specifically, the processing module sends the first request to the second short-range connection module. Because the second short-range connection module includes the variety of short-range communication components such as the Wi-Fi component, the Bluetooth component, and the Zigbee component. The processing module of the mobile phone sends the first request to the rescue processing device by using a short-range communication component capable of communicating with the rescue processing device.

705B: The short-range connection module of the mobile phone responds to the first request and sends the first distress information to the rescue processing device.

706A: The rescue processing device generates rescue information based on the first distress information, and sends the rescue information to the short-range connection module of the mobile phone.

With reference to 705A, the short-range connection module of the mobile phone can be connected to rescue processing device. Usually, after the mobile phone sends the first distress information, the short-range connection module of the mobile phone may also receive the rescue information sent by the rescue processing device. When the short-range connection module is abnormal and the mobile phone cannot receive the rescue information sent by the rescue processing device within preset time after sending out the first distress information, the mobile phone needs to switch to other communication means for distress. The other communication means may be cellular communication, satellite communication, communication between remote devices, and the like.

706B: After receiving the rescue information, the short-range connection module of the mobile phone sends the rescue information to the processing module of the mobile phone.

Usually, after the rescue processing device receives the first distress information sent by using the short-range connection module, the rescue processing device first contacts a rescue team closest to the distressed person to determine whether there is time to provide rescue for the distressed person based on a sending location of the first distress information. After confirming that the rescue team can provide rescue for the distressed person, the rescue processing device informs the rescue team of a basic situation of the distressed person and negotiates a specific rescue plan. After the rescue plan is determined, the rescue processing device notifies the rescue team to execute the rescue plan, and at the same time sends the rescue information to the mobile phone. In this way, it is convenient for the rescue team to contact the distressed person as soon as possible through a manner agreed in the rescue information upon arrival.

In some embodiments, the rescue processing device usually feeds back the rescue information to the distressed person based on communication means of the received first distress information. Therefore, the short-range connection module of the mobile phone may receive the rescue information sent from the rescue processing device, and then the short-range connection module sends the rescue information to the processing module. The processing module displays the received rescue information to the user through a display of the mobile phone to inform the user of a current rescue progress.

For example, the rescue information may include estimated arrival time of the rescue team, communication means between the rescue team and the distressed person, a forecast of weather information near a distress location of the distressed person, a preliminary emergency suggestion provided for the first distress information, text information, image information, audio information, or video information that is customized by the rescue team, and text information, image information, audio information, or video information that is fed back by an emergency contact of the distressed person, and the like.

The communication means between the rescue team and the distressed person included in the rescue information may be communication means adopted by the distressed person to send the first distress information. To ensure that rescue can be received more reliably, the rescue processing device may send the rescue information through various communication means, such as short-range connection communication, cellular network communication, satellite communication, and communication between remote devices.

A communication network between remote devices is a decentralized communication network established by the terminal device and the rescue processing device by using a preset frequency resource. The preset frequency resource includes an unauthorized frequency resource. Further, the preset frequency resource is a narrow band frequency resource.

A data type transmitted by the communication network between remote devices includes at least one of a picture, a text, a video, or voice.

For example, the communication network between remote devices may be a point-to-point communication network established by the mobile phone and the rescue processing device by using the preset frequency resource. The preset frequency resource may be a preset unauthorized frequency resource (for example, a resource other than a frequency resource used by an operator). Further, the preset frequency resource may be a narrow band frequency resource.

Because the mobile phone and the rescue processing device do not need to pass through any central device (for example, a base station device) when communicating with each other by using the communication network between remote devices, the communication network between remote devices may also be regarded as a decentralized communication network established by the mobile phone and the rescue processing device by using the preset frequency resource.

After a communication link is established by using the communication network between remote devices, many types of data, such as a picture, a text, a video, or voice, can be transmitted between the mobile phone and the rescue processing device.

A reason why the distressed person sends the first distress information is usually because the distressed person is located in a location with harsh environment and incomplete basic communication facilities like the wild, a disaster area, or a mountain. Therefore, the distressed person can be notified in the rescue information, and a communication function between remote devices can be turned on at a specified time point. Then, through the communication function between remote devices, the rescue team can find the distressed person in time and establish a rescue link in a process of approaching the distressed person.

Before the rescue team arrives, when a user status is consistent with a distress status in the first distress information, the following 707 is performed.

Specifically, a state described by user information, the user positioning information and the adverse sign information of the user in the first distress information is the distress status.

707: The processing module of the mobile phone establishes a connection with the rescue team based on the rescue information at specified time and through specified communication means.

After receiving the rescue information, the processing module analyzes the rescue information, and then establishes the rescue link with the rescue team through the communication means indicated by the rescue information based on the time point indicated in the rescue information. When the communication means indicated by the rescue information is not available, the processing module may attempt to establish a connection with the rescue team by using a module for communication between remote devices.

When the rescue link is successfully established, the distressed person can wait for rescue of the rescue team.

When the rescue link fails to be established, the processing module sends the first distress information to the rescue processing device again until the rescue link is successfully established. The re-sent first distress information may be sent by using any one of the short-range connection module, the cellular communication module, the satellite communication module, or the module for communication between remote devices.

Before the rescue team arrives, when the user status is inconsistent with the distress status in the first distress information, the following 708 to 711 are performed.

That the user status is inconsistent with the distress status in the first distress information may be specifically that user adverse sign information obtained when the user waits for rescue of the rescue team is inconsistent with the user adverse sign information in the first pre-distress information, may alternatively be that positioning information obtained when the user waits for rescue of the rescue team is inconsistent with the user positioning information in the first pre-distress information, or that the positioning information obtained when the user waits for rescue of the rescue team is inconsistent with the user positioning information in the first distress information.

708: The wearable smart device detects that a health status of the user changes, collects user health change data, generates second pre-distress information based on the user health change data, and sends the second pre-distress information to the processing module of the mobile phone by using the short-range connection module.

When the user waits for the rescue of the rescue team, the wearable smart device still monitors the status of the user. When the wearable smart device monitors that the health status of the user changes and a change interval exceeds a threshold, the wearable smart device re-generates the second pre-distress information based on latest changed health status of the user, to implement accurate rescue.

Alternatively, when the user perceives that the health status of the user changes, the user may manually input change information of the health status in the wearable smart device. After the wearable smart device receives the change information of the health status input by the user, the wearable smart device re-generates the second pre-distress information based on the change information of the health status.

Alternatively, the mobile phone is provided with a sensor for monitoring the health status of the user. When detecting that the health status of the user changes, the sensor may send change information of the health status of the user to the processing module, and the processing module re-generates the second pre-distress information based on the change information of the health status of the user.

Alternatively, when the user perceives that currently the health status of the user changes, the user may manually input second pre-distress information including the changed health status into the mobile phone in time, and the user interaction module of the mobile phone sends the second pre-distress information to the processing module after receiving the second pre-distress information.

709: After receiving the second pre-distress information, the processing module of the mobile phone generates second distress information based on the second pre-distress information, and re-sends the second distress information to the rescue processing device.

For the part in which the processing module generates the second distress information based on the second pre-distress information, refer to a manner of generating the first distress information from the first pre-distress information, and refer to 703 for details. After generating the second distress information, the processing module may sequentially try to send the second distress information to the rescue processing device by using the short-range connection module, the cellular communication module, the satellite communication module, and the module for communication between remote devices until the second distress information is successfully sent,. After the second distress information is sent. 706A to 711 may be continued.

710: The wearable smart device detects that a location of the user changes, generates third pre-distress information based on a changed user location state, and sends the third pre-distress information to the processing module of the mobile phone by using the short-range connection module.

When the user waits for the rescue of the rescue team, the wearable smart device still monitors the status of the user. When the wearable smart device detects that the location of the user changes and a change interval exceeds a threshold, the wearable smart device re-generates the third pre-distress information based on latest changed location of the user, to implement accurate rescue.

Alternatively, with reference to FIG. 1, when the user 101 waits for rescue, it appears that there is another person ahead. Then the user 101 goes in a direction of the another person to try to get help from the another person. But after walking for a while, the user 101 did not keep up with the another person. Because the user 101 has a poor sense of direction in the deep mountain and cannot return to a place where the first distress information is sent, the user 101 can only manually input the changed location information in the wearable smart device. After the wearable smart device receives the changed location information input by the user 101, the wearable smart device re-generates the third pre-distress information based on the changed location information.

Alternatively, the wearable smart device periodically detects the location of the user 101 at a fixed period. When it is detected that a location of the user 101 changes, detection is started all the time. When a moving speed of the user 101 is 0 and does not change in preset time, the wearable smart device determines that the location of the user 101 will not change, then the wearable smart device re-detects a location and generates the third pre-distress information based on the latest detected location.

Alternatively, the mobile phone is provided with a positioning module for monitoring the location of the user. When it is detected that the location of the user changes, the positioning module may re-detect the location of the user and send the detected newest location to the processing module. The processing module generates fourth distress information based on the detected newest location and sends the fourth distress information to the rescue processing device.

711: After receiving the third pre-distress information, the processing module of the mobile phone generates third distress information based on the third pre-distress information, and sends the third distress information to the rescue processing device.

For the part in which the processing module generates the third distress information based on the third pre-distress information, refer to a manner of generating the first distress information from the first pre-distress information, and refer to 703 for details. After generating the third distress information, the processing module can sequentially try to send the second distress information to the rescue processing device by using the short-range connection module, the cellular communication module, the satellite communication module, and the module for communication between remote devices. After the third distress information is sent, 706A to 711 may be continued.

It should be noted that, embodiments of this disclosure may not limit an execution sequence between 708 and 709 and 710 and 711. For example. 708 and 709 may be performed first, followed by 710 and 711. Alternatively, 710 and 711 may be performed first, followed by 708 and 709. Alternatively, 708 and 709 and 710 and 711 may be performed at the same time. Alternatively, only 708 and 709 are performed first, and 710 and 711 are not performed. Alternatively, only 710 and 711 are performed, and 708 and 709 are not performed. This may be specifically determined based on an actual use requirement.

For example, in FIG. 9A and FIG. 9B, another distress information sending method provided by an embodiment of this application is described below. After 701 to 704, the method further includes:

901: After determining that the short-range connection module cannot be connected to the rescue processing device, the processing module of the mobile phone determines whether a SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device.

When the mobile phone is in normal use, at least one SIM card is installed on the mobile phone. The processing module of the mobile phone determines whether the SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device, and specifically, the processing module of the mobile phone determines whether an operator cellular network corresponding to each SIM card can be connected to the rescue processing device.

A specific process in which the processing module of the mobile phone determines whether the SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device is as follows: The cellular communication module of the mobile phone obtains a signal strength measurement result and a resident status of the operator cellular network corresponding to each SIM card. When the operator cellular network corresponding to the SIM card successfully resides in a current area, and the signal strength measurement result is greater than or equal to a preset threshold, it is considered that the SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device. When the operator cellular network corresponding to the SIM card cannot successfully reside in a current area, or when the operator cellular network corresponding to the SIM card can successfully reside in the current area, but the signal strength measurement result is less than a preset threshold, the SIM card operator cellular network in the cellular communication module cannot be connected to the rescue processing device.

When the SIM card operator cellular network in the cellular communication module of the mobile phone can be connected to the rescue processing device, the first distress information can be sent to the rescue processing device by using the cellular communication module of the mobile phone. The first distress information can be sent in a form of a data service, can be sent in a form of a call, or can be sent in a form of a short message. Therefore, the set preset threshold can meet a network quality requirement of the data service, the call, or the short message.

In some embodiments, the cellular communication module may establish a connection with the rescue processing device by using a SIM card operator cellular network. When the mobile phone used by the distressed person has two SIM cards, the processing module can respectively determine whether the operator cellular network corresponding to each SIM card can be connected to the rescue processing device.

For example, when the SIM cards of the mobile phone used by the distressed person are a Mobile SIM card and a Unicom SIM card, the processing module can first determine whether the processing module can be connected to the rescue processing device by using a Mobile network, and then determine whether the processing module can be connected to the rescue processing device by using a Unicom network. Alternatively, the processing module can first determine whether the processing module can be connected to the rescue processing device by using a Unicom network, and then determine whether the processing module can be connected to the rescue processing device by using a Mobile network. Specific determining sequence is not limited in this application.

When the mobile phone used by the distressed person has only one SIM card, the processing module can directly determine whether an operator cellular network corresponding to the SIM card can be connected to the rescue processing device.

902A: After determining that the SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device, the processing module of the mobile phone sends a first request to the cellular communication module.

Usually, after the rescue processing device receives the first distress information sent by using the SIM card operator cellular network in the cellular communication module, the rescue processing device contact a rescue team closest to the distressed person to provide rescue for the distressed person based on a sending location of the first distress information. After the rescue processing device determines a corresponding rescue plan and rescue team, the rescue processing device sends rescue information to the mobile phone.

Specifically, the rescue processing device feeds back the rescue information to the distressed person based on communication means of the received first distress information. Therefore, the SIM card operator cellular network in the cellular communication module of the mobile phone can receive the rescue information sent from the rescue processing device, and then the cellular communication module sends the rescue information to the processing module. The processing module displays the received rescue information to the user through a display of the mobile phone to inform the user of a current rescue progress.

Before the rescue team arrives, when a user status is consistent with a distress status in the first distress information, the following 904 is performed.

904: Based on the rescue information, the processing module of the mobile phone establishes a connection with the rescue team at specified time and through specified communication means.

After receiving the rescue information, the processing module analyzes the rescue information, and then establishes the rescue link with the rescue team through the communication means indicated by the rescue information based on the time point indicated in the rescue information. The rescue processing device usually indicates communication means between the rescue team and the distressed person based on the communication means of the received first distress information.

Therefore, the processing module can establish the rescue link with the rescue team by using the SIM card operator cellular network in the cellular communication module. When the SIM card operator cellular network in the cellular communication module indicated by the rescue information is not available, the processing module may further attempt to establish a connection with the rescue team by using the module for communication between remote devices.

When the rescue link is successfully established, the distressed person can wait for rescue of the rescue team.

Before the rescue team arrives, when the user status is inconsistent with the distress status in the first distress information, the following 905 to 908 are performed.

905: The wearable smart device detects that a health status of the user changes, collects user health change data, generates second pre-distress information based on the user health change data, and sends the second pre-distress information to the processing module of the mobile phone by using the short-range connection module.

Refer to 709 for details.

906: After receiving the second pre-distress information, the processing module of the mobile phone generates second distress information based on the second pre-distress information, and sends the second distress information to the rescue processing device.

For the part in which the processing module generates the second distress information based on the second pre-distress information, refer to a manner of generating the first distress information from the first pre-distress information, and see 703 for details. After generating the second distress information, the processing module can sequentially try to send the second distress information to the rescue processing device by using the short-range connection module, the cellular communication module, the satellite communication module, and the module for communication between remote devices.

For the part in which the processing module generates the third distress information based on the third pre-distress information, refer to a manner of generating the first distress information from the first pre-distress information, and see 703 for details. After generating the third distress information, the processing module can sequentially try to send the second distress information to the rescue processing device by using the short-range connection module, the cellular communication module, the satellite communication module, and the module for communication between remote devices. After the third distress information is sent, 903A to 908 can be continued.

It should be noted that, embodiments of this disclosure may not limit an execution sequence between 905 and 906 and 907 and 908. For example. 905 and 906 may be performed first, followed by 907 and 908. Alternatively, 907 and 908 may be performed first, followed by 905 and 906. Alternatively, 905 and 906 and 907 and 908 may be performed at the same time. Alternatively, only 905 and 906 are performed first, and 907 and 908 are not performed. Alternatively, only 907 and 908 are performed, and 905 and 906 are not performed. This may be specifically determined based on an actual use requirement.

For example, in FIG. 10A to FIG. 10C, another distress information sending method provided by an embodiment of this application is described below. After 701 to 704, the method further includes:

1001: After determining that the short-range connection module cannot be connected to the rescue processing device, the processing module of the mobile phone determines whether a SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device.

Specifically, when the SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device, the processing module can directly send the first distress information to the rescue processing device by using the SIM card operator cellular network in the cellular communication module without continuing to perform 1002 and 1003A.

1002: After determining that the SIM card operator cellular network in the cellular communication module cannot be connected to the rescue processing device, the processing module of the mobile phone determines whether a non-SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device.

In some embodiments, when the operator cellular network corresponding to the SIM card installed in the mobile phone cannot be connected to the rescue processing device, it may continue to determine whether the non-SIM card operator cellular network can be connected to the rescue processing device. The non-SIM card operator cellular network is an operator other than an operator corresponding to the SIM card in the mobile phone.

For example, a non-SIM card operator cellular network may be a Telecom network when there are two SIM cards that are of a mobile phone used by a distressed person and that are a Mobile SIM card and a Unicom SIM card respectively. When only one SIM card of the mobile phone used by the distressed person is a Mobile SIM card, the non-SIM card operator cellular network may be a Telecom network or a Unicom network.

A specific process in which the processing module of the mobile phone determines whether the non-SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device is as follows: The cellular communication module of the mobile phone obtains a signal strength measurement result and a resident status of the non-SIM card operator cellular network. When the non-SIM card operator cellular network successfully resides in a current area, and the signal strength measurement result is greater than a preset threshold, it is considered that the non-SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device.

When the non-SIM card operator cellular network cannot successfully reside in a current area, or when the non-SIM card operator cellular network can successfully reside in the current area, but the signal strength measurement result is less than a preset threshold, the non-SIM card carrier cellular network in the cellular communication module cannot be connected to the rescue processing device.

When the non-SIM card operator cellular network in the cellular communication module of the mobile phone can be connected to the rescue processing device, the first distress information can be sent to the rescue processing device by using the cellular communication module of the mobile phone. The first distress information can only be sent in a form of an emergency call. Therefore, the set preset threshold can meet a network quality requirement of the emergency call.

After the rescue processing device determines a corresponding rescue plan and rescue team, the rescue processing device sends rescue information to the mobile phone.

Specifically, the rescue processing device feeds back the rescue information to the distressed person based on communication means of the received first distress information. Therefore, the non-SIM card operator cellular network in the cellular communication module of the mobile phone can receive the rescue information sent from the rescue processing device, and then the cellular communication module sends the rescue information to the processing module. The processing module displays the received rescue information to the user through a display of the mobile phone to inform the user of a current rescue progress.

Before the rescue team arrives, when a user status is consistent with a distress status in the first distress information, the following 1005 is performed.

1005: Based on the rescue information, the processing module of the mobile phone establishes a connection with the rescue team at specified time and through specified communication means.

After receiving the rescue information, the processing module analyzes the rescue information, and then establishes the rescue link with the rescue team through the communication means indicated by the rescue information based on the time point indicated in the rescue information. The rescue processing device usually indicates communication means between the rescue team and the distressed person based on the communication means of the received first distress information.

Therefore, the processing module can establish the rescue link with the rescue team by using the non-SIM card operator cellular network in the cellular communication module. When the non-SIM card operator cellular network in the cellular communication module indicated by the rescue information is not available, the processing module may further attempt to establish a connection with the rescue team by using the module for communication between remote devices.

When the rescue link is successfully established, the distressed person can wait for rescue of the rescue team.

After the second distress information is sent. 1004A to 1009 can be continued.

1008: The wearable smart device detects that a location of the user changes, generates third pre-distress information based on a changed user location state, and sends the third pre-distress information to the processing module of the mobile phone by using the short-range connection module.

After the third distress information is sent, 1004A to 1009 can be continued.

It should be noted that, embodiments of this disclosure may not limit an execution sequence between 1006 and 1007 and 1008 and 1009. For example. 1006 and 1007 may be performed first, followed by 1008 and 1009. Alternatively, 1008 and 1009 may be performed first, followed by 1006 and 1007. Alternatively, 1006 and 1007 and 1008 and 1009 may be performed at the same time. Alternatively, only 1006 and 1007 are performed first, and 1008 and 1009 are not performed. Alternatively, only 1008 and 1009 are performed, and 1006 and 1007 are not performed. This may be specifically determined based on an actual use requirement.

For example, in FIG. 11A to FIG. 11C, another distress information sending method provided by an embodiment of this application is described below. After 701 to 704, the method further includes:

1101: After determining that the short-range connection module cannot be connected to the rescue processing device, the processing module of the mobile phone determines whether a SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device.

1102: After determining that the SIM card operator cellular network in the cellular communication module cannot be connected to the rescue processing device, the processing module of the mobile phone determines whether a non-SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device.

Specifically, when the non-SIM card operator cellular network in the cellular communication module can be connected to the rescue processing device, the processing module can directly send the first distress information to the rescue processing device by using the non-SIM card operator cellular network in the cellular communication module without continuing to perform 1102 to 1104A.

1103: After determining that the non-SIM card operator cellular network in the cellular communication module cannot be connected to the rescue processing device, the processing module of the mobile phone determines whether the satellite communication module can be connected to the rescue processing device.

A process of determining whether the satellite communication module can be connected to the rescue processing device by the processing module is to be supplemented.

The mobile phone can obtain the signal strength measurement result of the satellite communication network and the resident status of the satellite communication network by using the satellite communication module, and then determine whether the satellite communication module can send the first distress information based on the signal strength measurement result and the resident status.

Specifically, when the satellite communication network resides in the current area and the signal strength measurement result exceed a preset threshold, it is considered that the satellite communication module can be connected to the rescue processing device. When the satellite communication network cannot successfully reside in the current area, or when the satellite communication network can successfully reside in the current area, but the signal strength measurement result is less than a preset threshold, it is considered that the satellite communication module cannot be connected to the rescue processing device.

When the satellite communication module of the mobile phone can be connected to the rescue processing device, the first distress information can be sent to the rescue processing device by using the satellite communication module of the mobile phone. The first distress information can be sent in a form of a data service, can be sent in a form of a call, or can be sent in a form of a short message. Therefore, the set preset threshold can meet a network quality requirement of the data service, the call, or the short message.

1104A: After determining that the satellite communication module can be connected to the rescue processing device, the processing module of the mobile phone sends a first request to the satellite communication module.

The first request is used for requesting to send the first distress information to the rescue processing device. The first request includes the first distress information.

1105B: After receiving the rescue information, the satellite communication module of the mobile phone sends the rescue information to the processing module of the mobile phone.

Usually, after the rescue processing device receives the first distress information sent by using the satellite communication module, the rescue processing device contacts a rescue team closest to the distressed person to provide rescue for the distressed person based on a sending location of the first distress information. After the rescue processing device determines a corresponding rescue plan and rescue team, the rescue processing device sends rescue information to the mobile phone.

Specifically, the rescue processing device feeds back the rescue information to the distressed person based on communication means of the received first distress information. Therefore, the satellite communication module of the mobile phone can receive the rescue information sent from the rescue processing device, and then the satellite communication module sends the rescue information to the processing module. The processing module displays the received rescue information to the user through a display of the mobile phone to inform the user of a current rescue progress.

Before the rescue team arrives, when a user status is consistent with a distress status in the first distress information, the following 1106 is performed.

1204: After determining that the satellite communication module cannot be connected to the rescue processing device, the processing module of the mobile phone determines whether the module for communication between remote devices can be connected to the rescue processing device.

The mobile phone performs signal scanning by using the module for communication between remote devices. When another nearby peer device supporting communication between remote devices is obtained through scanning, the module for communication between remote devices of the mobile phone establishes a connection with the peer device. After the connection is established, the module for communication between remote devices of the mobile phone sends an inquiry instruction to the peer device, the inquiry instruction includes an address of the rescue processing device, and the inquiry instruction is used for inquiring whether the peer device can be connected to the rescue processing device. After receiving the inquiry instruction, the peer device determines whether a communication module of the peer device can be connected to the rescue processing device, and after obtaining a determining result, the peer device sends an inquiry result to the module for communication between remote devices of the mobile phone. The inquiry result is used to inform the mobile phone whether the peer device can be connected to the rescue processing device. When the peer device can be connected to the rescue processing device, the module for communication between remote devices of the mobile phone can send the first distress information to the peer device, and the peer device forwards the first distress information to the rescue processing device.

The communication module of the peer device may include a short-range connection unit, a cellular network unit, a satellite communication unit, a unit for communication between remote devices, and the like. The peer device determines whether the communication module of the peer device can be connected to the rescue processing device, and can sequentially determine whether the short-range connection unit, the cellular network unit, the satellite communication unit and the unit for communication between remote devices can be connected to the rescue processing device.

1206B: After receiving the rescue information, the module for communication between remote devices of the mobile phone sends the rescue information to the processing module of the mobile phone.

Usually, after the rescue processing device receives the first distress information sent by using the module for communication between remote devices, the rescue processing device contacts a rescue team closest to the distressed person to provide rescue for the distressed person based on a sending location of the first distress information. After the rescue processing device determines a corresponding rescue plan and rescue team, the rescue processing device sends rescue information to the mobile phone.

Specifically, the rescue processing device feeds back the rescue information to the distressed person based on communication means of the received first distress information. Therefore, the module for communication between remote devices of the mobile phone can receive the rescue information sent from the rescue processing device, and then the module for communication between remote devices sends the rescue information to the processing module.

1305: After determining that the module for communication between remote devices cannot be connected to the rescue processing device, the processing module of the mobile phone performs 704 to 1305 again until the first distress information is sent to the rescue processing device.

Specifically, the processing module starts the module for communication between remote devices to scan a surrounding device that also starts a module for communication between remote devices. At the same time, the processing module sets preset time T, and in the preset time T, when the device that starts the module for communication between remote devices is not obtained through scanning, it is considered that the module for communication between remote devices cannot be connected to the rescue processing device.

After determining that the module for communication between remote devices cannot be connected to the rescue processing device, the processing module continues to determine whether the short-range connection module, the cellular communication module, the satellite communication module, or the module for communication between remote devices can be connected to the rescue processing device according to 704 to 1305. When there is a module that is in the short-range connection module, the cellular communication module, the satellite communication module, or the module for communication between remote devices and that can be connected to the rescue processing device, the first distress information is sent to the rescue processing device by using the module, and the following 1306 to 1311 is continued. When there is no module that is in the short-range connection module, the cellular communication module, the satellite communication module, or the module for communication between remote devices and that can be connected to the rescue processing device, the processing module continues to execute 704 to 1305 until the first distress information is sent.

1306: Receive rescue information sent by the rescue processing device.

Usually, after the rescue processing device receives the first distress information sent by using any one of the short-range connection module, the cellular communication module, the satellite communication module, or the module for communication between remote devices, the rescue processing device contacts a rescue team closest to the distressed person to provide rescue for the distressed person based on a sending location of the first distress information. After the rescue processing device determines a corresponding rescue plan and rescue team, the rescue processing device sends rescue information to the mobile phone.

For example, FIG. 14 illustrates another possible distress scenario in which a user 101 and companions go hiking in the snow. In the process of hiking in the snow, the weather suddenly changed, and a blizzard began. Gradually, bodies of the user 101 and the companions could no longer support the user 101 and the companions to continue hiking. At this time, everyone stays in place to rest, and because a temperature in the snow is very low and there is no exercise, a body temperature of everyone begins to drop.

At this time, after a smart watch worn by the user 101 detects that a temperature drop of the user 101 exceeds a preset threshold, the smart watch automatically generates first pre-distress information including the temperature drop, and then sends the first pre-distress information to a mobile phone of the user 101, and then the mobile phone of the user 101 generates first distress information based on the first pre-distress information, and then the mobile phone traverses a short-range connection module, a cellular communication module, a satellite communication module, and a module for communication between remote devices to try to send the first distress information to a rescue processing device. After the first distress information is sent, the user 101 can obtain rescue information fed back by the rescue processing device, and then the user can wait for rescue in a manner indicated by the rescue information. Usually, the user 101 can only think of making a distress call to contact the outside world. This can make full use of a communication function of the mobile phone and make the user 101 and the companions be rescued in time.

For example, FIG. 15 illustrates another possible distress scenario in which a user 101 is watching television, suddenly feels a tremor, and then sees a vase on a table swaying.

At this time, the user 101 realized that an earthquake occurs, and quickly hides under the table. In the process of hiding, a mobile phone 102 of the user 101 falls out of a pocket. In the process of the earthquake, an accident occurs on the user 101, and a smart watch worn by the user 101 detects that a heartbeat frequency drop of the user 101 exceeds a preset threshold, and then the smart watch automatically generates first pre-distress information including the heartbeat frequency drop, and then sends the first pre-distress information to the mobile phone 102 of the user 101. At this time, although the user 101 cannot actively pick up the mobile phone 102 to call for help due to the accident, the mobile phone 102 can receive the first pre-distress information by adopting a solution provided by this application, so that the call for help can be completed without cooperation of the user. The mobile phone 102 then generates first distress information based on the first pre-distress information, and then the mobile phone traverses a short-range connection module, a cellular communication module, a satellite communication module, and a module for communication between remote devices in an attempt to send the first distress information to a rescue processing device. After the first distress information is sent, the user 101 can obtain rescue information fed back by the rescue processing device, and then the user 101 can wait for rescue in a manner indicated by the rescue information.

For example, FIG. 16 illustrates another possible distress scenario in which a user 101 and companions are on a ship on a long voyage and a device indicating a direction on the ship suddenly fails, resulting in that the captain is incapable of determining the direction of the ship. The user 101 then inputs custom information on a mobile phone, where the custom information is information about the current dilemma.

At this time, after a user interaction module of the mobile phone receives the custom information, the user interaction module sends the custom information to a processing module, and the processing module generates first distress information based on the custom information and a pre-stored personal profile. Then, the mobile phone traverses a short-range connection module, a cellular communication module, a satellite communication module, and a module for communication between remote devices in an attempt to send the first distress information to a rescue processing device. After the first distress information is sent, the user 101 can obtain rescue information fed back by the rescue processing device, and then the user can wait for rescue in a manner indicated by the rescue information.

That an embodiment of the application provides a distress information sending method may be specifically providing a switching mechanism of communication means. This switching mechanism of communication means is applied in a scenario of emergency rescue. By using the switching mechanism of communication means, all possible communication means of a terminal used by a distressed person can be traversed to send distress information. Therefore, missing an available communication network is avoided and the distressed person can be rescued in time.
