Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a communication method and electronic equipment. Background Art

[0002] With the development of technology, electronic devices have powerful processing capabilities. Due to various considerations of cost, power consumption and user usage frequency, existing electronic devices are usually not equipped with a transceiver module required by a certain communication technology, and thus do not have the function of communicating with other electronic devices using the communication technology.

[0003] In order to meet the user's demand for using the communication technology, the electronic device can be connected to an auxiliary device, and the auxiliary device is provided with a transceiver module corresponding to the communication technology. Through the connection between the electronic device and the auxiliary device, the electronic device can control the transceiver module in the auxiliary device to send information to other electronic devices according to the user's operation, and can also process the information received by the transceiver module in the auxiliary device, thereby realizing the user's demand for using the communication technology.

[0004] However, in some emergency situations, if the user needs to use the communication technology, the user needs to carry the electronic device and the auxiliary device, the number of devices carried is large, and the user experience is poor. Summary of the invention

[0005] The present application provides a communication method and electronic device, which can reduce the number of devices that users need to carry in emergency situations and improve user experience.

[0006] In a first aspect, a communication method is provided, which is applied to a first electronic device, the method comprising: receiving rescue start information sent by a second electronic device through a first connection with the second electronic device; monitoring a channel in response to receiving the rescue start information; and sending a distress message when receiving the rescue information through the channel.

[0007] In the solution of the present application, after the first electronic device receives the rescue start information sent by the second electronic device, it can monitor the channel and send a distress message when the rescue information is received through the channel. That is to say, after receiving the rescue start information, the monitoring process of the channel and the sending of the distress message by the first electronic device do not depend on the existence of the first connection. Therefore, after the second electronic device sends the rescue start information to the first electronic device, emergency rescue can be achieved using the first electronic device, and the user no longer needs to carry the second electronic device, which improves the convenience of user use in emergency rescue situations and improves the user experience.

[0016] In some possible implementations, the monitoring of the channel and the sending of the distress message are performed using wireless ad hoc network technology.

[0017] Wireless ad hoc network technology does not rely on preset infrastructure. It has the characteristics of temporary networking, rapid deployment, no control center, and strong anti-destruction.

[0019] In some possible implementations, the first connection is disconnected during the process in which the first electronic device monitors the channel.

[0020] In some possible implementations, the method further includes: determining the rescue activation information according to a user operation, wherein the rescue activation information includes the help request information.

[0021] In some possible implementations, determining the rescue start information based on the user operation includes: using the application layer in the open system interconnection reference model to process the user operation to obtain the rescue start information; the first electronic device is used to receive and process the signal transmitted in the channel using a wireless communication module to obtain the rescue information, and the wireless communication module includes multiple layers in the open system interconnection reference model except the application layer.

[0022] In some possible implementations, the multiple layers include other layers in the Open Systems Interconnection Reference Model except the application layer.

[0023] In some possible implementations, the monitoring of the channel and the sending of the distress message are performed by the first electronic device using wireless ad hoc network technology.

After the low-frequency baseband signal is processed by the baseband processor, it is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to a speaker 170A, a receiver 170B, etc.), or displays an image or video through a display screen 194.

In some embodiments, the pressure sensor 180A can be set on the display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. The capacitive pressure sensor can be a parallel plate including at least two conductive materials. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the intensity of the pressure according to the change in capacitance. When a touch operation acts on the display screen 194, the electronic device 100 detects the touch operation intensity according to the pressure sensor 180A. The electronic device 100 can also calculate the touch position according to the detection signal of the pressure sensor 180A. In some embodiments, touch operations acting on the same touch position but with different touch operation intensities can correspond to different operation instructions. For example: when a touch operation with a touch operation intensity less than the first pressure threshold acts on the short message application icon, an instruction to view the short message is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on the short message application icon, an instruction to create a new short message is executed.

[0094] The gyro sensor 180B can be used to determine the motion posture of the electronic device 100. In some embodiments, the angular velocity of the electronic device 100 around three axes (i.e., x, y, and z axes) can be determined by the gyro sensor 180B. The gyro sensor 180B can be used for anti-shake shooting. For example, when the shutter is pressed, the gyro sensor 180B detects the angle of the electronic device 100 shaking, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to offset the shaking of the electronic device 100 through reverse movement to achieve anti-shake. The gyro sensor 180B can also be used for navigation and somatosensory game scenes.

[0095] The air pressure sensor 180C is used to measure air pressure. In some embodiments, the electronic device 100 calculates the altitude through the air pressure value measured by the air pressure sensor 180C to assist positioning and navigation.

[0096] The magnetic sensor 180D includes a Hall sensor. The electronic device 100 can use the magnetic sensor 180D to detect the opening and closing of the flip leather case. In some embodiments, when the electronic device 100 is a flip phone, the electronic device 100 can detect the opening and closing of the flip cover according to the magnetic sensor 180D. Then, according to the detected opening and closing state of the leather case or the opening and closing state of the flip cover, the flip cover can be automatically unlocked.

[0097] The acceleration sensor 180E can detect the magnitude of the acceleration of the electronic device 100 in all directions (generally three axes). When the electronic device 100 is stationary, the magnitude and direction of gravity can be detected. It can also be used to identify the posture of the electronic device and is applied to applications such as horizontal and vertical screen switching and pedometers.

[0098] The distance sensor 180F is used to measure the distance. The electronic device 100 can measure the distance by infrared or laser. In some embodiments, when shooting a scene, the electronic device 100 can use the distance sensor 180F to measure the distance to achieve fast focusing.

[0099] The proximity light sensor 180G may include, for example, a light emitting diode (LED) and a light detector, such as a photodiode. The light emitting diode may be an infrared light emitting diode. The electronic device 100 emits infrared light outward through the light emitting diode. The electronic device 100 uses a photodiode to detect infrared reflected light from nearby objects. When sufficient reflected light is detected, it can be determined that there is an object near the electronic device 100. When insufficient reflected light is detected, the electronic device 100 can determine that there is no object near the electronic device 100. The electronic device 100 can use the proximity light sensor 180G to detect that the user holds the electronic device 100 close to the ear to talk, so as to automatically turn off the screen to save power. The proximity light sensor 180G can also be used in leather case mode and pocket mode to automatically unlock and lock the screen.

[0100] The ambient light sensor 180L is used to sense the ambient light brightness. The electronic device 100 can adaptively adjust the brightness of the display screen 194 according to the perceived ambient light brightness. The ambient light sensor 180L can also be used to automatically adjust the white balance when taking pictures. The ambient light sensor 180L can also cooperate with the proximity light sensor 180G to detect whether the electronic device 100 is in a pocket to prevent accidental touches.

[0101] The fingerprint sensor 180H is used to collect fingerprints. The electronic device 100 can use the collected fingerprint characteristics to implement fingerprint unlocking, access application locks, fingerprint photography, fingerprint call answering, etc.

[0102] The temperature sensor 180J is used to detect temperature. In some embodiments, the electronic device 100 uses the temperature detected by the temperature sensor 180J to execute a temperature processing strategy. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 reduces the performance of a processor located near the temperature sensor 180J to reduce power consumption and implement thermal protection. In other embodiments, when the temperature is lower than another threshold, the electronic device 100 heats the battery 142 to avoid abnormal shutdown of the electronic device 100 due to low temperature. In other embodiments, when the temperature is lower than another threshold, the electronic device 100 performs a boost on the output voltage of the battery 142 to avoid abnormal shutdown caused by low temperature.

[0103] The touch sensor 180K is also called a "touch panel". The touch sensor 180K can be set on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, also called a "touch screen". The touch sensor 180K is used to detect touch operations acting on or near it. The touch sensor can pass the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through the display screen 194. In other embodiments, the touch sensor 180K can also be set on the surface of the electronic device 100, which is different from the position of the display screen 194.

[0104] The bone conduction sensor 180M can obtain a vibration signal. In some embodiments, the bone conduction sensor 180M can obtain a vibration signal of a vibrating bone block of the vocal part of the human body. The bone conduction sensor 180M can also contact the human pulse to receive a blood pressure beat signal. In some embodiments, the bone conduction sensor 180M can also be set in an earphone and combined into a bone conduction earphone. The audio module 170 can parse out a voice signal based on the vibration signal of the vibrating bone block of the vocal part obtained by the bone conduction sensor 180M to realize a voice function. The application processor can parse the heart rate information based on the blood pressure beat signal obtained by the bone conduction sensor 180M to realize a heart rate detection function.

[0105] The key 190 includes a power key, a volume key, etc. The key 190 may be a mechanical key or a touch key. The electronic device 100 may receive key input and generate key signal input related to user settings and function control of the electronic device 100.

[0106] Motor 191 can generate vibration prompts. Motor 191 can be used for incoming call vibration prompts, and can also be used for touch vibration feedback. For example, touch operations acting on different applications (such as taking pictures, audio playback, etc.) can correspond to different vibration feedback effects. For touch operations acting on different areas of the display screen 194, motor 191 can also correspond to different vibration feedback effects. Different application scenarios (for example: time reminders, receiving messages, alarm clocks, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

[0107] The indicator 192 may be an indicator light, which may be used to indicate the charging status, power changes, messages, missed calls, notifications, etc.

[0108] The SIM card interface 195 is used to connect a SIM card. The SIM card can be connected to and separated from the electronic device 100 by inserting it into the SIM card interface 195 or pulling it out from the SIM card interface 195. The electronic device 100 can support 1 or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 195 can support Nano SIM cards, Micro SIM cards, SIM cards, and the like. Multiple cards can be inserted into the same SIM card interface 195 at the same time. The types of the multiple cards can be the same or different. The SIM card interface 195 can also be compatible with different types of SIM cards. The SIM card interface 195 can also be compatible with external memory cards. The electronic device 100 interacts with the network through the SIM card to implement functions such as calls and data communications. In some embodiments, the electronic device 100 uses an eSIM, i.e., an embedded SIM card. The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

[0109] The software system of the electronic device 100 may adopt a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application takes the Android system of the layered architecture as an example to exemplify the software structure of the electronic device 100.

[0110] Figure 2 1 is a software structure diagram of the electronic device 100 of the embodiment of the present application. The layered architecture divides the software into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, namely, the application layer, the application framework layer, the system library of the Android runtime (Android runtime), and the kernel layer. The application layer can include a series of application packages.

[0111] like Figure 2 As shown, the application package may include camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message and other applications.

[0112] The application framework layer provides an application programming interface (API) and a programming framework for the applications in the application layer. The application framework layer includes some predefined functions.

[0113] like Figure 2 As shown, the application framework layer may include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, and the like.

[0114] The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the screen, capture the screen, etc.

[0115] Content providers are used to store and retrieve data and make it accessible to applications. The data may include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

[0116] The view system includes visual controls, such as controls for displaying text, controls for displaying images, etc. The view system can be used to build applications. A display interface can be composed of one or more views. For example, a display interface including a text notification icon can include a view for displaying text and a view for displaying images.

[0117] The phone manager is used to provide communication functions of the electronic device 100, such as management of call status (including connecting, hanging up, etc.).

[0118] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0119] The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is displayed in the status bar, a prompt sound is emitted, an electronic device vibrates, an indicator light flashes, etc.

[0120] Android runtime includes core libraries and virtual machines. Android runtime is responsible for scheduling and management of the Android system.

[0121] The core library consists of two parts: one is the function that needs to be called by the Java language, and the other is the Android core library.

[0122] The application layer and the application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

[0123] The system library may include multiple functional modules, such as surface manager, media libraries, 3D graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), etc.

[0124] The surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

[0125] The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0126] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0127] A 2D graphics engine is a drawing engine for 2D drawings.

[0128] The kernel layer is the layer between hardware and software. The kernel layer can include driver modules such as display driver, camera driver, audio driver and sensor driver.

[0129] Figure 3 Schematic diagram of a communication system applicable to an embodiment of the present application. Figure 3 , the communication system includes a first electronic device 310 and a second electronic device 320.

[0130] The second electronic device 320 is provided with a long range radio (LoRa) module 321. The LoRa module 321 is used to implement LoRa communication. LoRa communication uses spread spectrum technology, and the sensitivity is closer to Shannon's limit theorem, which reduces the signal-to-noise ratio requirement and has a longer propagation distance.

[0131] The first electronic device 310 and the second electronic device 320 can be connected by wire. In the case where the first electronic device 310 and the second electronic device 320 are connected by wire, the first electronic device 310 can use the LoRa module 321 of the second electronic device 320 to perform LoRa communication with other electronic devices.

[0132] The LoRa module 321 can be understood as a radio frequency transceiver module or a communication interface for implementing LoRa communication. The communication information sent by other electronic devices received by the LoRa module 321 can be sent to the first electronic device 310, and the first electronic device can process the communication information. Thus, the cost, volume and power consumption of the second electronic device 320 can be reduced.

[0133] In order to achieve LoRa communication with other electronic devices, the user needs to carry the first electronic device 310 and the second electronic device 320. In emergency situations such as when rescue is needed, the user needs to carry more electronic devices, resulting in a poor user experience.

[0134] In order to solve the above problems, an embodiment of the present application provides a communication method.

[0135] Combine the following Figures 4 to 19 The communication method provided in the embodiment of the present application is described in detail.

[0136] Figure 4 4 is a schematic flow chart of a communication method provided in an embodiment of the present application. The method is applied to a first electronic device. The method includes steps S410 to S430, and these steps are described in detail below.

[0137] Step S410: receiving rescue start information sent by a second electronic device through a first connection with the second electronic device.

[0138] It should be understood that before S410, the first electronic device and the second electronic device may establish a first connection.

[0139] The first connection between the first electronic device and the second electronic device may be established by wired communication technology or wireless communication technology. For example, the first connection may be a USB connection, a Bluetooth connection, a Wi-Fi connection, or a device-to-device (D2D) connection.

[0140] When a first connection exists between the first electronic device and the second electronic device, the first electronic device can receive control commands and data sent by the second electronic device.

[0141] For example, when a first connection exists between a first electronic device and a second electronic device, the second electronic device can communicate with other electronic devices by using the first electronic device. Exemplarily, the first electronic device can have a communication function that the second electronic device can or cannot implement. For example, the first electronic device can have a wireless ad hoc network module, and the second electronic device can communicate with other electronic devices other than the first electronic device by using the wireless ad hoc network module of the first electronic device through the first connection.

[0142] The wireless ad hoc network module is set up based on wireless ad hoc network technology. A wireless ad hoc network is a temporary multi-hop autonomous system composed of a group of mobile nodes with wireless transceivers. It does not rely on preset infrastructure and has the characteristics of temporary networking, rapid deployment, no control center, and strong anti-destruction.

[0143] Wireless ad hoc networks can utilize the routing and forwarding functions of mobile terminals to communicate without infrastructure, thus making up for the lack of network communication infrastructure. Wireless ad hoc network technology provides a solution for the collaborative work of electronic devices.

[0144] The electronic device that communicates using the wireless ad hoc network module can serve as a node in the wireless ad hoc network and communicate with other electronic devices in the wireless ad hoc network.

[0145] Exemplarily, the wireless ad hoc network module may be a long range radio (LoRa) module. LoRa is a low power wide area network (LPWAN) technology. Low power wide area network (LPWAN) is a network layer technology of the Internet of Things that has emerged in recent years to meet the communication needs of long distances and low power consumption in the Internet of Things. It has the characteristics of low cost, low power consumption, wide coverage, and large connections.

[0146] The second electronic device may send rescue start information to the first electronic device through the first connection to instruct the first electronic device to enter an emergency rescue state.

[0147] Step S420: In response to receiving the rescue start information, monitor the channel.

[0148] After receiving the rescue start information through the first connection, the first electronic device may enter an emergency rescue state. In the emergency rescue state, the first electronic device may monitor the channel.

[0149] The monitoring of channels can also be understood as the monitoring of time-frequency resources.

[0150] In an emergency rescue state, both the first electronic device and the second electronic device need to reduce power consumption as much as possible. Maintaining the first connection will increase the power consumption of the first electronic device or the second electronic device. Therefore, in an emergency rescue state, the first connection can be disconnected. The first electronic device and / or the second electronic device can disconnect the first connection.

[0151] After receiving the rescue start information, the first electronic device may no longer communicate with other electronic devices using communication technologies other than the wireless ad hoc network, thereby reducing the power consumption of the first electronic device.

[0152] Step S430: sending a distress message when receiving the rescue message through the channel.

[0153] Compared with the state of sending signals, the electronic device in the signal receiving state has lower power consumption. When the channel is monitored, the first electronic device is in the signal receiving state. After receiving the rescue start information, the first electronic device can use the communication protocol stack to monitor the channel, and when receiving the rescue information through the channel, send a distress signal, which can reduce the power consumption of the first electronic device.

[0154] It should be understood that after receiving the rescue start information, the first electronic device can establish a connection with the rescue electronic device that sent the rescue start information, and send a distress message to the rescue electronic device through the connection. Alternatively, after receiving the rescue start information, the first electronic device can send the distress message by broadcasting.

[0155] The distress message may be preset. The distress message may also be determined by the first electronic device or the second electronic device according to a user operation. In the case where the distress message is determined according to a user operation, the information content of the distress message is more flexible. For example, in the case where the distress message is determined according to a user operation, the distress message may be used to indicate one or more of the number of people waiting for rescue, the health conditions of the people waiting for rescue, the environmental conditions, the location information, etc.

[0156] Providing an interactive device in the first electronic device will increase the size of the first electronic device and reduce the convenience of the user carrying the first electronic device. Therefore, the second electronic device may be provided with an interactive device. The second electronic device may obtain user operations by using the interactive device, and determine rescue start information according to the user operations, and the rescue start information includes a distress message.

[0157] The first electronic device may monitor the channel by using a wireless communication module. The wireless communication module may include all or part of the layers in an open system interconnect (OSI) reference model.

[0158] For example, the wireless communication module may include multiple layers in addition to the application layer. The second electronic device may use the application layer in the OSI reference model to process the user operation to obtain the rescue start information. Thus, the second electronic device is used to interact with the user, and the application layer set in the second electronic device can realize the processing of the user operation; the first electronic device is used for wireless communication in emergency rescue situations, and the multiple layers in the OSI reference model set in the first electronic device can realize the reception and processing of the signals transmitted in the channel, and the settings of each layer in the OSI reference model are more reasonable.

[0159] The rescue information may have a preset format or content. Alternatively, the rescue information may be any valid information determined by the first electronic device. For example, the rescue information may be a preset medium access control (MAC) frame; or, the rescue information may be any one of a plurality of information such as connection establishment request information and connection establishment response information. The MAC layer in the OSI reference model may determine whether the received information is a preset MAC frame.

[0160] The data link layer in the OSI reference model includes the MAC layer, and the data link layer and the lower physical layer can be set in the first electronic device. A layer higher than the data link layer, such as a network layer and a transport layer, can also be set in the first electronic device. Exemplarily, a layer higher than the data link layer and a layer lower than the layer can be set in the first electronic device, and a layer higher than the layer can be set in the second electronic device, and the layer is a layer other than the application layer in the OSI reference model.

[0161] In some embodiments, all layers of the OSI reference model except the application layer can be set in the first electronic device. That is, the wireless communication module can include a transport layer, a network layer, a data link layer, and a physical layer, that is, it includes other layers of the OSI reference model except the application layer. Thus, the first electronic device is less dependent on the function of the second electronic device, and all electronic devices provided with the application layer in the OSI reference model can be used as the second electronic device, thereby improving the breadth and convenience of the application of the first electronic device.

[0162] It should be understood that the first electronic device can use the wireless communication module to send a distress message.

[0163] The wireless communication module may be a wireless ad hoc network module. That is, the monitoring of the channel and the sending of the distress message may be performed by the first electronic device using wireless ad hoc network technology. Using wireless ad hoc network technology for rescue may increase the possibility of the user being rescued.

[0164] The communication technology used for the first connection and the communication technology used by the first electronic device to monitor the channel may be the same as or different from each other.

[0165] Through S410 to S430, after the first electronic device receives the rescue start information sent by the second electronic device, it can monitor the channel and send a distress message when receiving the rescue information through the channel. After receiving the rescue start information, the first electronic device's monitoring process of the channel and the sending of the distress message do not depend on the existence of the first connection. Therefore, after the second electronic device sends the rescue start information to the first electronic device, emergency rescue can be achieved using the first electronic device, and the user no longer needs to carry the second electronic device, which improves the convenience of user use in emergency rescue situations and improves the user experience.

[0166] Combine the following Figures 5 to 16 , taking the first connection as a USB connection, and the first electronic device using wireless ad hoc network technology to perform channel monitoring and send distress information as an example, a communication system including the first electronic device and the second electronic device is described.

[0167] Figure 5 It is a schematic structural diagram of an electronic device provided in an embodiment of the present application.

[0168] Figure 5 The electronic device 500 shown may be a first electronic device. The electronic device 500 includes a communication chip 501, a battery 502, a power management unit (PMU) 503, a universal serial bus (USB)-inter-integrated circuit (I2C) converter 504, a control key 505, a crystal 506, a memory 507, a buzzer 508 and a USB interface.

[0169] The communication chip 501 has the functions of wireless ad hoc network communication, Bluetooth communication, and Wi-Fi communication.

[0170] The crystal 506 is used to provide a clock signal for the communication chip 501 .

[0171] The USB-I2C converter 504 is used to convert the I2C signal output by the communication chip 501 into a USB signal, or to convert the USB signal received through the USB interface 509 into an I2C signal and transmit it to the communication chip 501 .

[0172] When the electronic device 500 is connected to another electronic device via the USB interface 509, the PMU 503 uses the power provided by the other electronic device to charge the battery 502. When the electronic device 500 is not connected to another electronic device via the USB interface 509, the PMU 503 controls the battery 502 to supply power to components in the electronic device 500. The other electronic device may be a second electronic device.

[0173] The first electronic device and other electronic devices can be connected through various communication methods, that is, the communication connection between the first electronic device 500 and other electronic devices can be implemented using various communication technologies. Figure 6 As shown, the various communication technologies that can be used for the connection between the first electronic device 500 and other electronic devices may include Bluetooth, Wi-Fi, USB, wireless ad hoc network technology, etc.

[0174] Bluetooth technology is an open global standard for wireless data and voice communications. It uses ultra high frequency (UHF) radio waves in the industrial scientific medical (ISM) band of 2.4 to 2.485 GHz. It is a radio technology that supports short-range communication between devices (generally within 10 meters).

[0175] Wi-Fi, also known as "mobile hotspot", is a wireless networking technology that actually converts wired network signals into wireless signals and uses wireless routers for electronic devices that support its technology.

[0176] USB is a serial bus standard and also a technical specification for input and output interfaces. USB is an external bus standard that regulates the connection and communication between electronic devices and external devices. The USB interface has hot-swap function. The USB interface can connect to a variety of peripherals. USB has the advantages of fast transmission speed, easy use, hot-swap support, flexible connection, independent power supply, etc., and is widely used.

[0177] Wireless ad hoc networking technology can meet the needs of a large number of information exchanges between people. Some wireless ad hoc networking technologies can transmit farther than other wireless methods under the same power consumption conditions, achieving the unity of low power consumption and long distance. For example, LoRa, as a wireless ad hoc networking technology, has a 3-5 times longer communication distance than traditional wireless RF communication under the same power consumption.

[0178] When the first electronic device is connected to other electronic devices via Bluetooth, it can have functions such as item search and distance reminder. When the first electronic device is connected to other electronic devices via Wi-Fi, it can have functions such as wireless USB flash drive and smart home control. When the first electronic device is connected to other electronic devices via USB, it can have the function of assisting wireless ad hoc network communication. When the first electronic device is connected to other electronic devices via wireless ad hoc network, it can have the function of emergency rescue.

[0179] The switching of the first electronic device 500 between different communication modes and the switching of functions can be referred to in Figure 7 Description.

[0180] Figure 7 Detailed description of the invention The communication method includes steps S701 to S705.

[0181] Step S701: power on the first electronic device.

[0182] The various communication technologies that may be used for the connection between the second electronic device and other electronic devices may include Bluetooth, Wi-Fi, USB, etc.

[0183] After the first electronic device 500 is powered on, it can be connected to the second electronic device via Bluetooth, Wi-Fi, or USB. In other words, after the first electronic device is powered on, it can be discovered via Bluetooth and connected via Wi-Fi.

[0184] After S701 , S702 , S703 , or S704 may be performed.

[0185] Step S702: The first electronic device establishes a Bluetooth connection with the second electronic device.

[0186] The second electronic device may be a mobile terminal such as a mobile phone.

[0187] The second electronic device can discover the first electronic device 500 through Bluetooth and connect to the first electronic device 500 through Bluetooth. Figure 8 As shown, after the first electronic device 500 establishes a Bluetooth connection with the second electronic device 810, data and commands can be transmitted via Bluetooth to achieve Bluetooth communication.

[0188] When the first electronic device 500 is connected to the second electronic device 810 via Bluetooth, functions such as object search and distance reminder can be implemented.

[0189] Multiple Bluetooth antennas may be provided in the first electronic device 500 and / or the second electronic device 810. An electronic device provided with multiple Bluetooth antennas receives a signal sent by a Bluetooth antenna in another electronic device. According to the relative positions of the multiple antennas and the phase difference of the signals received by the multiple antennas, the angle of arrival (AOA) may be determined. According to the difference between the time when the signal is sent and received, the distance between the two electronic devices may be determined. Thus, according to the AOA and the distance, the relative position between the two electronic devices may be determined.

[0190] Alternatively, an electronic device provided with multiple Bluetooth antennas uses the multiple antennas to send signals, and an electronic device provided with at least one Bluetooth antenna can determine the angle of departure (AOA) based on the signals received by the at least one Bluetooth antenna and the relative positions between the multiple Bluetooth antennas. Thus, the relative positions between the two electronic devices can be determined based on the AOD and the distance.

[0191] like Fig. 9 As shown, the second electronic device 810 can display a direction icon 920 and a distance icon 930 on a graphical user interface (GUI) 910. The icon 920 can indicate the direction of the first electronic device 500 relative to the second electronic device 810, and the distance icon 930 can indicate the distance between the first electronic device 500 and the second electronic device 810.

[0192] Or, if Fig.10 As shown, the second electronic device 810 can also display a play icon 1020 using the graphical user interface 1010. When the user clicks the play icon 1020, the second electronic device 810 can send play information to the first electronic device 500 through the Bluetooth connection between the second electronic device 810 and the first electronic device 500, so that the first electronic device 500 makes a sound, which is convenient for the user to find the first electronic device 500. The first electronic device 500 can make a sound using a buzzer or the like.

[0193] The function of searching for objects at close range can be achieved by displaying the relative position between the second electronic device 810 and the first electronic device 500, or by the second electronic device sending information to the first electronic device 500 via a Bluetooth connection so that the first electronic device 500 emits a sound.

[0194] The first electronic device 500 can emit a sound when the Bluetooth connection is disconnected to achieve the function of the principle reminder.

[0195] For the implementation of the item search function in long-distance situations, please refer to Fig.11 .

[0196] The second electronic device 810 may generate a public key and a private key corresponding to the first electronic device 500, and upload the public key and the device identification of the first electronic device 500 to the cloud 1140. The cloud 1140 may be a cloud server.

[0197] The first electronic device 500 may send search information in a broadcasting manner via Bluetooth, and the search information includes a device identification of the first electronic device 500. Electronic devices within the Bluetooth signal coverage of the first electronic device 500 may receive the search information. The electronic device receiving the search information may be the good Samaritan device 1130.

[0198] The good Samaritan device 1130 can use the device identifier carried in the search information to obtain the public key corresponding to the first electronic device 500 from the cloud 1140. The good Samaritan device 1130 can encrypt the location information using the public key and upload the encrypted location information to the cloud 1140.

[0199] It should be understood that the location information can be used to indicate the location of the good Samaritan device 1130, or the location of the first electronic device 500 determined by the good Samaritan device 1130. In the case where the location information can be used to indicate the location of the good Samaritan device 1130, the location of the good Samaritan device 1130 can be used as the location of the first electronic device 500.

[0200] The second electronic device 810 can receive the encrypted location information from the cloud, and decrypt it using the private key corresponding to the first electronic device 500, thereby obtaining the decrypted location information and determining the location of the first electronic device 500.

[0201] After determining the location of the first electronic device 500 , the second electronic device 810 may display a map using a graphical user interface, and display the location of the first electronic device 500 on the map according to the location of the first electronic device 500 .

[0202] It should be understood that after the second electronic device 810 generates the public key and private key corresponding to the first electronic device 500, the public key and private key corresponding to the first electronic device 500 can be shared with other electronic devices of the same user. The electronic devices of the same user can be electronic devices logged in with the same account. Thus, the electronic devices with the same user can receive the encrypted location information from the cloud, and use the private key corresponding to the first electronic device 500 to decrypt it, thereby obtaining the decrypted location information and determining the location of the first electronic device 500.

[0203] After S702, if the Bluetooth between the first electronic device 500 and the second electronic device is disconnected, the first electronic device 500 is restored to the state after S701, that is, Bluetooth is discoverable and Wi-Fi is connectable, and S702, S703 or S704 can be performed.

[0204] Step S703 : The first electronic device 500 establishes a Wi-Fi connection with the second electronic device 810 .

[0205] When the first electronic device 500 and the second electronic device 810 are connected to the same Wi-Fi wireless local area network, the first electronic device 500 and the second electronic device 810 are connected to each other by Wi-Fi.

[0206] When the first electronic device 500 and the second electronic device 810 are connected by Wi-Fi, the first electronic device 500 and the second electronic device 810 can transmit data and information. The first electronic device 500 can be used as a wireless storage device of the second electronic device 810. The wireless storage device can also be called a wireless USB flash disk (USB flash disk, USB disk, U disk). The second electronic device 810 can view and manage the data stored in the first electronic device 500.

[0207] like Fig.12 As shown in (a) of FIG. 1 , when the first electronic device 500 is connected to the second electronic device 810 by Wi-Fi, the second electronic device 810 may display a graphical user interface 1210. The graphical user interface 1210 includes an icon 1220 of the first electronic device 500. After obtaining the operation of the user clicking the icon 1220, the second electronic device 810 may display the following Fig.12 The graphical user interface 1230 is shown in (b) of FIG. The graphical user interface 1210 includes icons of a disk 1241 and a disk 1242 in the electronic device 500 .

[0208] When the first electronic device 500 is connected to a Wi-Fi wireless local area network, the first electronic device 500 can also control other IoT devices connected to the Wi-Fi wireless local area network.

[0209] like Fig.13 As shown, the second electronic device 810 can be connected to the first electronic device 500. The first electronic device can bind the first electronic device 500 and the Internet of Things device 1340 according to the user's binding operation, and upload the correspondence between the identifier of the first electronic device 500 and the identifier of the Internet of Things device 1340 to the server.

[0210] When the first electronic device 500 and the Internet of Things device 1340 are connected to the same Wi-Fi wireless local area network, the first electronic device 500 can control the Internet of Things device 1340 according to the user's control operation on the first electronic device 500. The first electronic device 500 sends control information to the server using the Wi-Fi wireless local area network according to the user's control operation, and the control information includes the identifier of the electronic device 500, the identifier of the Internet of Things device 1340, and the control instruction information. The server determines that the identifier of the first electronic device 500 in the control information and the identifier of the Internet of Things device 1340 have a corresponding relationship based on at least one corresponding relationship. After determining that the identifier of the first electronic device 500 in the control information and the identifier of the Internet of Things device 1340 have a corresponding relationship, the server can send the control instruction information to the Internet of Things device 1340 using the Wi-Fi wireless local area network. The control instruction information is used to control the Internet of Things device 1340.

[0211] It should be understood that the user's binding operation may be an operation of the user on a user interface provided by an application program acquired by the second electronic device 810. The application program, as a client, may send the corresponding relationship between the identifier of the first electronic device 500 and the identifier of the Internet of Things device 1340 to the server. The first electronic device 500 may be provided with a control key 505. The user's control operation on the first electronic device 500 may be pressing the control key 505.

[0212] Exemplarily, the IoT device 1340 may be a desk lamp, and the control instruction information is used to control the IoT device 1340, i.e., the desk lamp, to turn on or off, so that the first electronic device 500 can control turning the light on or off.

[0213] After S703, if the Wi-Fi between the first electronic device 500 and the second electronic device 810 is disconnected, the first electronic device 500 is restored to the state after S701, that is, Bluetooth is discoverable and Wi-Fi is connectable, and S702, S703 or S704 can be performed.

[0214] Step S704: The first electronic device establishes a USB connection with the second electronic device.

[0215] The USB interface has the feature of being hot-swappable, and the user can insert the first electronic device 500 into the USB interface of the second electronic device 810 to establish a USB connection between the first electronic device 500 and the second electronic device 810 .

[0216] When the first electronic device 500 is connected to the second electronic device 810 via USB, the second electronic device can charge the first electronic device 500 and transmit data and information to the first electronic device 500.

[0217] There may be one or more communication technology connections between the first electronic device 500 and the second electronic device 810. Exemplarily, when multiple communication technology connections may be established between the first electronic device 500 and the second electronic device 810, a connection with the communication technology with the highest priority may be established according to the user's set priority or the default priority. For example, a USB connection may have the highest priority, a Bluetooth connection may have a higher priority, and a Wi-Fi connection may have a lower priority.

[0218] The first electronic device 500 is provided with a wireless ad hoc network module. The second electronic device can utilize the wireless ad hoc network module in the first electronic device 500 to perform wireless ad hoc network communication with other electronic devices. That is to say, when there is a USB connection between the first electronic device 500 and the second electronic device 810, the first electronic device 500 has the function of assisting wireless ad hoc network communication, assisting the second electronic device 810 connected to the first electronic device 500 via USB to communicate with other electronic devices via wireless ad hoc network technology, and realizing data and information transmission between the second electronic device 810 and other electronic devices via wireless ad hoc network.

[0219] The wireless ad hoc network module may include multiple layers in the open system interconnect (OSI) reference model. Fig.14 and Fig.15 The OSI reference model and electronic devices provided with the OSI reference model are described and combined Fig.16 , the settings of the OSI reference model in the first electronic device 500 and the second electronic device 810 are explained.

[0220] Fig.14 A structural diagram of an OSI reference model is shown.

[0221] The OSI reference model may include multiple layers such as a physical layer 1401 , a data link layer 1402 , a network layer 1403 , a transport layer 1404 , and an application layer 1405 .

[0222] The physical layer (PHY) 1401 is the lowest layer in the OSI reference model, which mainly defines the electrical, mechanical, process and functional standards of the system. Such as: voltage, physical data rate, maximum transmission distance, physical connector and other similar characteristics. The main function of the physical layer is to use the transmission medium to provide physical connection for the data link layer and is responsible for the physical transmission of data streams. The basic unit of physical layer transmission is bit stream, that is, 0 and 1, which is the most basic electrical signal or optical signal, and is the most basic physical transmission feature.

[0223] The physical layer 1401 can implement functions such as channel assessment, carrier sensing, coding modulation, framing, and signal reception and transmission.

[0224] Coding and modulation technologies include narrowband modulation technology (such as frequency-shift keying (FSK), phase shift keying (PSK), etc.), spread spectrum modulation technology (such as frequency hopping spread spectrum (FHSS), direct sequence spread spectrum (DSSS), etc.), and carrier-free ultra-wideband modulation technology.

[0225] The data link layer 1402 establishes a data link connection between communication entities. The basic unit of transmission is "frame", and provides error control and flow control services for the network layer. The data link layer includes the medium access control (MAC) sublayer and the logical link control (LLC) sublayer. The main task of the medium access control sublayer is to specify how to transmit frames on the physical line. The logical link control sublayer manages the communication between devices on the same network link. The data link control sublayer is mainly responsible for logically identifying different protocol types and encapsulating them. That is to say, the data link control sublayer will accept network protocol data, packet datagrams and add more control information to transmit the packet to its target device.

[0226] The data link layer 1402 can perform link layer management and channel management. Through link layer management, a link data path is established and maintained. Through channel management, transmit receive (TRX) scheduling is achieved.

[0227] The network layer 1403 mainly creates logical links for data transmission between nodes, and selects the best path for packets through routing algorithms, thereby realizing functions such as congestion control and network interconnection. The network layer is a key layer that overlooks the network with routers as the highest nodes. It is responsible for the routing selection work of transmitting packets from the source network to the target network. The Internet is a collection of multiple networks. It is with the help of the routing path selection function of the network layer that the connection between multiple networks can be smooth and information can be shared. The services provided by the network layer are connection-oriented and connectionless services. Connection-oriented services are reliable connection services. Before data is exchanged, a connection must be established, and then data is transmitted. After the end, the service that previously established the connection is terminated. The network layer implements connection-oriented services in the form of virtual circuit services. Connectionless services are unreliable services that cannot prevent the loss, retransmission or disorder of messages. The advantage of connectionless services is that their service methods are flexible and convenient, and they are very fast. The network layer implements connectionless services in the form of datagram services.

[0228] The network layer 1403 can perform link monitoring and routing management, thereby realizing network layer data processing.

[0229] The transport layer 1404 is an interface layer between the upper and lower layers in the network architecture. The transport layer is not just a separate structural layer, but the core of the entire analysis system protocol. The transport layer mainly provides end-to-end services for users and handles transmission problems such as datagram errors and data packet order. The transport layer is a key layer in the computer communication architecture. It shields the communication details of the lower layer data from the upper layer, so that users do not need to consider the details of the physical layer, data link layer and network layer. The transport layer uses the network connection service provided by the network layer. According to system requirements, you can choose to use connection-oriented services or connectionless services for data transmission.

[0230] The transport layer 1404 can perform congestion control and adjust the transport layer data path. The transport layer 1404 can also perform security management and encrypt and decrypt data in the transport layer data path. The transport layer can also be used to implement relays. The transport layer 1404 can also determine whether the received data has packet loss, control retransmission in the case of packet loss, and sort the received data to improve the reliability of data transmission.

[0231] The application layer 1405 is the highest layer in the OSI reference model and is directly facing the user. The user's communication content must be resolved by the application process, which requires the application layer to use different application protocols to solve different types of application requirements and ensure that the low-level communication protocols used by these different types of applications are consistent. The application layer contains several independent user general service protocol modules to provide dedicated program services for communication between network users. It should be noted that the application layer is not an application program, but provides services for applications.

[0232] The application layer 1405 provides services for applications that provide voice or text information transmission, ranging and other functions.

[0233] The OSI reference model may also include a session layer and a presentation layer.

[0234] The main function of the session layer is to maintain the transmission connection between two nodes, ensure that point-to-point transmission is not interrupted, and manage data exchange and other functions. The session layer establishes, manages, and terminates sessions in the application process. The session layer can also decide which communication method to use, full-duplex communication or half-duplex communication, through dialogue control. The session layer coordinates requests and responses through its own protocol.

[0235] The presentation layer provides services for the representation of information transmitted between application processes. The layers below the presentation layer mainly complete the reliable data transmission from the source to the destination, and the presentation layer is more concerned with the syntax and semantics of the transmitted data. The main function of the presentation layer is to handle the representation of information exchanged between two communication systems, mainly including data format changes, data encryption and decryption, data compression and decompression, etc. Under the premise of a certain network bandwidth, the smaller the data compression, the faster the transmission rate, so the data compression and decompression of the presentation layer are regarded as the key factors in controlling the network transmission rate. The data encryption service provided by the presentation layer is an important network security element, which ensures the secure transmission of data and is also the key that various security services pay the most attention to. The services provided by the presentation layer to the application layer include: syntax conversion, syntax selection and connection management.

[0236] Exemplarily, the presentation layer and the session layer may also be arranged in the application layer 1405 .

[0237] An ad hoc network is a network that combines mobile communications and computer networks. The information exchange of the network adopts the packet switching mechanism in computer networks. The electronic devices in the ad hoc network are portable terminals that can be moved. Each electronic device in the ad hoc network has both the functions of a router and a host.

[0238] In the OSI reference model for wireless ad hoc network technology, the application layer 1405 can be used for group member management, and can also be used to present the state of the ad hoc network and group members to the user. The transport layer 1404 and the network layer 1403 can be used for authentication management and security monitoring. Authentication management includes identity authentication. In the process of two electronic devices establishing a wireless ad hoc network connection, the two electronic devices can perform identity authentication. The data link layer 1402 is used for address allocation and inter-group roaming. Address allocation can be understood as setting the identification of different electronic devices in the ad hoc network. Inter-group roaming can be understood as the electronic device provided with the OSI reference model for wireless ad hoc networks switching between different ad hoc networks. The physical layer 1401 can be used for system management. System management can be understood as the control and management of the sleep state and wake-up state of the operating system in the electronic device provided with the OSI reference model for wireless ad hoc networks.

[0239] Fig.15 It is a structural diagram of an electronic device.

[0240] In an electronic device provided with an OSI reference model for a wireless ad hoc network, a software system of the electronic device may include an application layer, an application framework layer, a hardware abstraction layer, and a kernel layer.

[0241] The application layer includes wireless ad hoc network applications. Users can interact with electronic devices and generate control commands and data by using the user interface provided by the wireless ad hoc network applications.

[0242] The application framework layer is used for application layer management. Application layer management is used for group member maintenance, network status management, business management, etc., so as to provide services for application layer services such as voice and SMS provided by wireless ad hoc network applications.

[0243] The hardware abstraction layer (HAL) is an interface layer between the operating system kernel and the hardware circuit, and its purpose is to abstract the hardware.

[0244] HAL includes a wireless ad hoc network software development kit (SDK). The wireless ad hoc network SDK is used to transmit control commands and data between the framework layer and the kernel layer.

[0245] The kernel layer includes chip drivers, which are used to obtain maintenance data and serial peripheral interface (SPI) drivers.

[0246] The kernel layer may include a transmission node for transmitting control commands and data with the HAL. The transmission node may also be referred to as a wireless ad hoc network communication node.

[0247] Maintenance and testing data can be understood as log information, which can include information related to troubleshooting (debugging).

[0248] The kernel layer can distribute and aggregate the transmitted instructions and data. Aggregation can be understood as sending instructions and data from different business modules through the same underlying channel. Distribution can be understood as sending instructions and data from the underlying channel to the business module corresponding to the instruction or data. In the embodiment of the present application, the underlying channel can be understood as a wireless ad hoc network chip.

[0249] The SPI driver can transmit maintenance data, wireless ad hoc network control commands, and wireless ad hoc network data with the SPI in the wireless ad hoc network chip in the electronic device.

[0250] The wireless ad hoc network chip includes SPI and a processor. The SPI transmits maintenance and measurement data and wireless ad hoc network control commands to the processor, and transmits wireless ad hoc network data from the SPI driver of the kernel layer to the processor of the wireless ad hoc network chip, or from the processor of the wireless ad hoc network chip to the SPI driver of the kernel layer.

[0251] The wireless ad hoc network chip may be provided with a wireless ad hoc network module. The wireless ad hoc network module may include Fig.14 The OSI reference model shown has layers other than the application layer, and the application layer can be set outside the wireless ad hoc network chip. The function of the application layer can be realized by using a chip with a software system in the electronic device.

[0252] The wireless ad hoc network chip may be provided with a real time operating system (RTOS) for utilizing the wireless ad hoc network module to implement wireless ad hoc network communication between the electronic device in which the chip is located and other electronic devices.

[0253] The processor of the wireless ad hoc network chip is used to establish a wireless ad hoc network connection with other electronic devices according to the wireless ad hoc network control command, and use the wireless ad hoc network module to process the wireless ad hoc network data from the kernel layer and send it to the other electronic device, or use the wireless ad hoc network data module to process the signal received from the other electronic device, obtain the wireless ad hoc network data and transmit it to the kernel layer.

[0254] Specifically, the wireless ad hoc network module may include a transport layer, a network layer, a data link layer and a physical layer.

[0255] When the first electronic device 500 is connected to the second electronic device 810 via USB, the wireless ad hoc network chip may be provided in the first electronic device 500 .

[0256] Fig.16 1 is a schematic structural diagram of a communication system provided in an embodiment of the present application. The communication system includes a first electronic device 500 and a second electronic device 810.

[0257] The first electronic device 500 is provided with a wireless ad hoc network chip and a USB-I2C converter 504. The second electronic device 810 is provided with an application layer, a framework layer, a hardware abstraction layer and a kernel layer.

[0258] and Fig.15 The structure shown is different, the hardware abstraction layer of the second electronic device 810 is provided with a USB device layer, and in the kernel layer of the second electronic device 810, a USB driver is provided in the chip driver.

[0259] The USB device layer is used to transmit control commands and data between the framework layer and the kernel layer. The USB driver is used to establish a USB connection with the first electronic device 500.

[0260] The communication chip 501 includes a wireless ad hoc network chip. The USB-I2C converter 504 is used to convert the I2C signal output by the wireless ad hoc network chip into a USB signal and transmit it to the USB driver, or convert the USB signal received from the USB driver into an I2C signal and transmit it to the wireless ad hoc network chip.

[0261] The functions of the application layer in the OSI reference model may be implemented by the second electronic device 810 , and the other layers in the OSI reference model except the application layer may be implemented by the wireless ad hoc network chip of the first electronic device 500 .

[0262] Thus, the second electronic device 810 can perform wireless ad hoc network communication with other electronic devices by utilizing other layers except the application layer in the OSI reference model provided in the second electronic device 810 .

[0263] When the first electronic device 500 and the second electronic device 810 are connected via USB, S705 may be performed.

[0264] Step S705 : the first electronic device 500 receives the rescue start information sent by the second electronic device 810 .

[0265] After S705, the first electronic device 500 may enter an emergency rescue state to implement an emergency rescue function.

[0266] When the first electronic device 500 is in an emergency rescue state, the first electronic device can be in a receiving state, and the wireless ad hoc network chip can detect the channel to receive rescue information. When receiving a rescue signal, the first electronic device 500 sends a rescue message.

[0267] like Fig.17 As shown, the rescue information may be sent by the third electronic device 1710. The third electronic device 1710 may receive the rescue information sent by the first electronic device 500. The third electronic device 1710 may be an electronic device used for search and rescue, or may be another electronic device passing near the first electronic device 500.

[0268] The rescue start information may include a help message. The help message may be determined according to the user's operation on the second electronic device 810. The help message may include one or more of the number of people waiting for rescue, health conditions of the people waiting for rescue, environmental conditions, location information, etc.

[0269] The second electronic device 810 may generate and send rescue activation information to the first electronic device 500 according to user operation, where the rescue activation information includes a help request message.

[0270] After receiving the rescue start information, the first electronic device 500 may store the rescue information and send the rescue information when receiving a rescue signal.

[0271] The first electronic device 500 can establish a connection with the third electronic device that sends the rescue information, thereby sending the rescue information to the third electronic device in a unicast manner. Alternatively, the first electronic device 500 can send the rescue information in a broadcast manner. Sending the rescue information in a broadcast manner can avoid information interaction with the third electronic device during the process of establishing the connection in a unicast case, thereby reducing the power consumption of the first electronic device 500.

[0272] After S705, for example, after the first electronic device 500 enters an emergency rescue state, the USB connection between the second electronic device 810 and the first electronic device 500 may be disconnected to reduce the overall power consumption of the communication system where the first electronic device 500 and the second electronic device 810 are located.

[0273] After the first electronic device 500 receives the rescue start information sent by the second electronic device 810, the first electronic device 500 may output disconnection reminder information, which may instruct the user to unplug the interface inserted into the USB interface of the second electronic device 810 to disconnect the USB connection between the first electronic device 500 and the second electronic device 810. The interface inserted into the USB interface of the second electronic device 810 may be the USB interface of the first electronic device 500. Alternatively, the interface inserted into the USB interface of the second electronic device 810 may also be a USB interface of a data cable, and the USB interface of the data cable is connected to the first electronic device 500 when the first electronic device 500 and the second electronic device 810 are connected via USB.

[0274] After the first electronic device 500 receives the rescue start information sent by the second electronic device 810, the first electronic device 500 may also autonomously disconnect the USB connection between the first electronic device 500 and the second electronic device 810, that is, the first electronic device 500 may no longer receive the electrical signal of the USB interface connected to the second electronic device 810, or may no longer process the electrical signal of the USB interface connected to the second electronic device 810.

[0275] The rescue start information can be understood as application layer information, which is used to control the first electronic device 500 to enter an emergency rescue state.

[0276] In an emergency rescue state, the first electronic device 500 may use the transport layer and the network layer to perform identity authentication with other electronic devices. Alternatively, in an emergency rescue state, the first electronic device 500 may no longer perform identity authentication with other electronic devices.

[0277] The first electronic device 500 can use the transport layer or the network layer to add the identifier of the first electronic device 500 to the sent distress message, so that the electronic device receiving the distress message can authenticate the first electronic device 500. For example, the electronic device receiving the distress message can determine whether the identifier of the first electronic device 500 belongs to a blacklist identifier, etc. In the case that the identifier of the first electronic device 500 does not belong to the blacklist, the electronic device receiving the distress message can output distress indication information to inform the user of the electronic device, so as to rescue the user of the first electronic device 500. It should be understood that the user of the first electronic device 500 can be the user of the second electronic device 810. The electronic device receiving the distress message may no longer authenticate the first electronic device 500 that sent the distress message after receiving the distress message.

[0278] In an emergency rescue state, the first electronic device 500 may no longer use the transport layer to encrypt the transmitted signal, so as to increase the possibility of the distress signal being received and recognized, and improve the possibility of the user being rescued.

[0279] The first electronic device 500 may utilize the data link layer for rescue access, thereby implementing a rescue request and a rescue response.

[0280] The rescue information may have a preset first MAC frame format, so that the first electronic device 500 may process the signal received by the physical layer using the MAC layer in the data link layer to determine whether the signal carries the rescue information.

[0281] The first electronic device 500 can use the MAC layer in the data link layer to encapsulate the distress message, and the encapsulated distress message. After that, the first electronic device 500 can use the physical layer to send the encapsulated distress message. The distress message encapsulated by the MAC layer can have a preset second MAC frame format. The first MAC frame format and the second MAC frame format can be the same or different. The rescue message can be understood as a rescue request, and the distress message can be understood as a rescue response.

[0282] The electronic device receiving the encapsulated distress information sent by the first electronic device 500 can determine that the received information carries the distress information according to the second MAC frame format. In other words, the information with the second MAC frame format carries the distress information, and the second MAC frame format is the format of the distress information, indicating the existence of the distress information.

[0283] The first electronic device 500 may monitor the channel using the physical layer. When the first electronic device 500 is in an emergency rescue state, the channel monitored by the physical layer may be called a rescue channel.

[0284] When the first electronic device 500 is in an emergency rescue state, the first electronic device 500 can obtain a reset operation of the user. The first electronic device 500 includes a control key 505, and the reset operation can be a long press, short press, or continuous press operation of the control key 505 by the user.

[0285] According to the reset operation of the user, the first electronic device 500 may proceed to S706.

[0286] Step S706: the first electronic device 500 is reset.

[0287] After being reset, the first electronic device 500 is restored to a state of being discoverable by Bluetooth and connectable by Wi-Fi.
