Description

[0001] This application claims the priority of the Chinese patent application filed with the China Patent Office on October 17, 2018, with application number 201811210028.2 and application name “A positioning method and device”, the entire contents of which are incorporated by reference in this application. Technical Field

[0002] The present application relates to the field of terminals, and in particular to a positioning method and device. Background Art

[0003] Smart bracelets, smart watches, pet trackers, luggage trackers, mobile phones and other mobile smart hardware (hereinafter referred to as terminals) generally have a location positioning function. Usually, in order to accurately locate the terminal, a high-precision positioning method can be used to locate the terminal multiple times.

[0004] However, for scenarios such as pet retrieval, picking up people, and tracking moving targets, it is necessary to accurately approach the target and try to avoid the terminal on the target object shutting down due to power consumption. In this case, frequent positioning of the terminal using high-precision positioning methods will increase the power consumption of the terminal, and the terminal may automatically shut down soon. Summary of the invention

[0005] The embodiments of the present application provide a positioning method and device, which can reduce the power consumption of a terminal during the positioning process.

[0006] In the first aspect, the embodiment of the present application provides a positioning method, including: a first device determines a first distance between the first device and the second device; when the first distance is greater than or equal to a first threshold, the first device sends a first indication message to the second device, and the first indication message is used to indicate that the second device adopts a first positioning method; when the first distance is less than a second threshold, the first device sends a second indication message to the second device, and the second indication message is used to indicate that the second device adopts a second positioning method; wherein the second threshold is less than or equal to the first threshold, and the positioning accuracy of the first positioning method is less than the positioning accuracy of the second positioning method. That is, when the first distance between the first device and the second device is large (greater than or equal to the first threshold), the second device can adopt a positioning method with lower accuracy (the first positioning method); when the first distance between the first device and the second device is small (less than the second threshold, and the second threshold is less than the first threshold), the second device can adopt a positioning method with higher accuracy (the second positioning method). In this way, it can be avoided that the second terminal device always adopts a high-precision positioning method, and the power consumption of the terminal can be reduced during the positioning process, and the possibility of the terminal shutting down can be reduced.

[0007] In a possible implementation, the positioning frequency of the first positioning method is the same as or different from the positioning frequency of the second positioning method. That is, the positioning frequency of the first positioning method may be greater than, less than, or equal to the positioning frequency of the second positioning method. In other words, when a positioning method with lower accuracy is adopted, a lower positioning frequency may be adopted, or a higher positioning frequency may be adopted; when a positioning method with higher accuracy is adopted, a lower positioning frequency may be adopted, or a higher positioning frequency may be adopted, and this application does not make any limitation.

[0008] In a possible implementation, the positioning frequency of the first positioning method is less than the positioning frequency of the second positioning method. When a positioning method with lower accuracy is used, a lower positioning frequency is used at the same time, which can further save the power consumption of the terminal and reduce the possibility of terminal shutdown. When a positioning method with higher accuracy is used, a higher positioning frequency is used at the same time, which can more accurately locate the position of the terminal.

[0009] In a possible implementation, the method further includes: the first device receives first positioning information obtained by the second device using a first positioning method, the first positioning information is used to indicate the first position of the second device; the first device displays the first position of the second device in a first display mode based on the first positioning information; or the first device receives second positioning information obtained by the second device using a second positioning method, the second positioning information is used to indicate the second position of the second device; the first device displays the second position of the second device in a second display mode based on the second positioning information; wherein the display accuracy of the first display mode is less than the display accuracy of the second display mode. The first display mode may be a lower-precision display mode. For example, a geometric figure (e.g., a circle) may be used to represent the first position of the second device, and the error range of the first position of the second device is within 100m. The second display mode may be a higher-precision display mode. For example, a point may be used to represent the first position of the second device, and the error range of the first position of the second device is within 5m.

[0010] In a possible implementation, after the first device displays the position of the second device in the first display mode, the method further includes: receiving a first operation of the user on the position of the second device, and displaying the position of the second device in the second display mode in response to the first operation. In this way, when the user is not satisfied with the display accuracy of the first display mode, the first operation can be performed, so that the first device displays the position of the second device in the second display mode, and the display accuracy of the second display mode is greater than that of the first display mode, thereby improving the user experience.

[0086] The modem may include a modulator and a demodulator. The modulator is used to modulate the low-frequency baseband signal to be sent into a medium-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. 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, a receiver, etc.), or displays an image or video through a display screen. In some embodiments, the modem may be an independent device. In some embodiments, the modem may be independent of the processor and be set in the same device as the RF module or other functional modules.

[0087] The communication module 160 can provide a communication processing module for wireless communication solutions including wireless local area networks (WLAN) (for example, wireless fidelity (WiFi)), Bluetooth, global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc., which are applied to the mobile phone 100. The communication module 160 can be one or more devices integrating at least one communication processing module. The communication module receives electromagnetic waves via antenna 2, modulates and filters the electromagnetic wave signals, and sends the processed signals to the processor. The communication module 160 can also receive the signal to be sent from the processor, modulate the frequency, amplify it, and convert it into electromagnetic waves for radiation through antenna 2.

[0088] In some embodiments, the antenna 1 of the mobile phone 100 is coupled to the radio frequency module, and the antenna 2 is coupled to the communication module. This allows the mobile phone 100 to communicate with the network and other devices through wireless communication technology. The wireless communication technology may include global svstem for mobile communications (GSM), general packet radio service (GPRS), code division multiple access (CDMA), wideband code division multiple access (WCDMA), time-division code division multiple access (TD-SCDMA), LTE, 5G new wireless communication (New Radio, NR), BT, GNSS, WLAN, NFC, FM, and / or IR technology. 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) and / or a satellite based augmentation system (SBAS). Thus, the mobile phone 100 can obtain the positioning (location) information of the mobile phone.

[0089] The mobile phone 100 implements the display function through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing, which connects the display screen and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs that execute program instructions to generate or change display information.

[0090] The display screen 194 is used to display images, videos, etc. The display screen includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED), Miniled, MicroLed, Micro-oLed, quantum dot light emitting diodes (QLED), etc. In some embodiments, the mobile phone 100 may include 1 or N display screens, where N is a positive integer greater than 1.

[0091] Still Figure 1 As shown, the mobile phone 100 can realize the shooting function through ISP, camera 193, video codec, GPU, display screen and application processor.

[0092] The ISP is used to process the data fed back by the camera. For example, when taking a photo, the shutter is opened, and the light is transmitted to the camera photosensitive element through the lens. The light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converts it into an image visible to the naked eye. The ISP can also perform algorithm optimization on the noise, brightness, and skin color of the image. The ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, the ISP can be set in the camera 193.

[0093] The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the mobile phone 100 may include 1 or N cameras, where N is a positive integer greater than 1.

[0094] The digital signal processor is used to process digital signals, and can process not only digital image signals but also other digital signals. For example, when the mobile phone 100 is selecting a frequency point, the digital signal processor is used to perform Fourier transform on the frequency point energy.

[0095] Video codecs are used to compress or decompress digital videos. Mobile phone 100 may support one or more codecs. Thus, mobile phone 100 may play or record videos in multiple coding formats, such as MPEG1, MPEG2, MPEG3, MPEG4, etc.

[0096] NPU is a neural network (NN) computing processor. By drawing on the structure of biological neural networks, such as the transmission mode between neurons in the human brain, it can quickly process input information and can also continuously self-learn. Through NPU, the intelligent cognition of the mobile phone 100 can be realized, such as: image recognition, face recognition, voice recognition, text understanding, etc.

[0097] The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the mobile phone 100. The external memory card communicates with the processor through the external memory interface to implement a data storage function, such as storing music, video and other files in the external memory card.

[0098] The internal memory 121 can be used to store computer executable program codes, which include instructions. The processor 110 executes various functional applications and data processing of the mobile phone 100 by running the instructions stored in the internal memory 121. The memory 121 may include a program storage area and a data storage area. Among them, the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc. The data storage area can store data created during the use of the mobile phone 100 (such as audio data, a phone book, etc.), etc. In addition, the memory 121 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, other volatile solid-state storage devices, a universal flash storage (UFS), etc.

[0099] The mobile phone 100 can implement audio functions such as music playing and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the earphone interface 170D, and the application processor.

[0100] The audio module is used to convert digital audio information into analog audio signal output, and is also used to convert analog audio input into digital audio signal. The audio module can also be used to encode and decode audio signals. In some embodiments, the audio module can be arranged in the processor 110, or some functional modules of the audio module can be arranged in the processor 110.

[0101] The speaker 170A, also called a "speaker", is used to convert an audio electrical signal into a sound signal. The mobile phone 100 can listen to music or listen to a hands-free call through the speaker.

[0102] The receiver 170B, also called a "handset", is used to convert audio electrical signals into sound signals. When the mobile phone 100 receives a call or voice message, the voice can be received by placing the receiver close to the human ear.

[0103] Microphone 170C, also called "microphone" or "microphone", is used to convert sound signals into electrical signals. When making a call or sending a voice message, the user can put the sound signal into the microphone by putting the mouth close to the microphone. The mobile phone 100 can be provided with at least one microphone. In some embodiments, the mobile phone 100 can be provided with two microphones, which can not only collect sound signals but also realize noise reduction function. In some embodiments, the mobile phone 100 can also be provided with three, four or more microphones to realize the collection of sound signals, noise reduction, identification of sound sources, and realization of directional recording function, etc.

[0104] The earphone interface 170D is used to connect a wired earphone, and the earphone interface can be a USB interface, or a 3.5 mm open mobile terminal platform (OMTP) standard interface, or a cellular telecommunications industry association of the USA (CTIA) standard interface.

[0105] The pressure sensor 180A is used to sense the pressure signal and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor can be set on the display screen. There are many types of pressure sensors, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. A capacitive pressure sensor can be a parallel plate including at least two conductive materials. When a force acts on the pressure sensor, the capacitance between the electrodes changes. The mobile phone 100 determines the intensity of the pressure based on the change in capacitance. When a touch operation acts on the display screen, the mobile phone 100 detects the touch operation intensity according to the pressure sensor. The mobile phone 100 can also calculate the touch position according to the detection signal of the pressure sensor. 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.

[0106] The gyroscope sensor 180B can be used to determine the motion posture of the mobile phone 100. In some embodiments, the angular velocity of the mobile phone 100 around three axes (i.e., x, y, and z axes) can be determined by the gyroscope sensor. The gyroscope sensor can be used for anti-shake shooting. For example, when the shutter is pressed, the gyroscope sensor detects the angle of the shaking of the mobile phone 100, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to offset the shaking of the mobile phone 100 through reverse movement to achieve anti-shake. The gyroscope sensor can also be used for navigation and somatosensory game scenes.

[0107] The air pressure sensor 180C is used to measure air pressure. In some embodiments, the mobile phone 100 calculates the altitude through the air pressure value measured by the air pressure sensor to assist positioning and navigation.

[0108] The magnetic sensor 180D includes a Hall sensor. The mobile phone 100 can use the magnetic sensor to detect the opening and closing of the flip leather case. In some embodiments, when the mobile phone 100 is a flip phone, the mobile phone 100 can detect the opening and closing of the flip cover according to the magnetic sensor. 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 automatic unlocking and other features are set.

[0109] The acceleration sensor 180E can detect the magnitude of the acceleration of the mobile phone 100 in various directions (generally three axes). When the mobile phone 100 is stationary, the magnitude and direction of gravity can be detected. It can also be used to identify the terminal posture and is applied to applications such as horizontal and vertical screen switching and pedometers.

[0110] The distance sensor 180F is used to measure the distance. The mobile phone 100 can measure the distance by infrared or laser. In some embodiments, when shooting a scene, the mobile phone 100 can use the distance sensor to measure the distance to achieve fast focusing.

[0111] 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. Infrared light is emitted outward through the light emitting diode. The photodiode is used 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 mobile phone 100. When insufficient reflected light is detected, it can be determined that there is no object near the mobile phone 100. The mobile phone 100 can use the proximity light sensor to detect that the user is holding the mobile phone 100 close to the ear to talk, so as to automatically turn off the screen to save power. The proximity light sensor can also be used in the leather case mode and the pocket mode to automatically unlock and lock the screen.

[0112] The ambient light sensor 180L is used to sense the ambient light brightness. The mobile phone 100 can adaptively adjust the display brightness according to the perceived ambient light brightness. The ambient light sensor can also be used to automatically adjust the white balance when taking pictures. The ambient light sensor can also cooperate with the proximity light sensor to detect whether the mobile phone 100 is in a pocket to prevent accidental touches.

[0113] The fingerprint sensor 180H is used to collect fingerprints. The mobile phone 100 can use the collected fingerprint characteristics to achieve fingerprint unlocking, access application locks, fingerprint photography, fingerprint call answering, etc.

[0114] The temperature sensor 180J is used to detect temperature. In some embodiments, the mobile phone 100 uses the temperature detected by the temperature sensor to execute a temperature processing strategy. For example, when the temperature reported by the temperature sensor exceeds a threshold, the mobile phone 100 reduces the performance of the processor located near the temperature sensor to reduce power consumption and implement thermal protection.

[0115] The touch sensor 180K, also known as a "touch panel", can be disposed on a display screen and used to detect a touch operation applied thereto or near the touch sensor. The detected touch operation can be transmitted to an application processor to determine the type of touch event and provide a corresponding visual output through the display screen.

[0116] The bone conduction sensor 180M can obtain a vibration signal. In some embodiments, the bone conduction sensor can obtain a vibration signal of a vibrating bone block of the human body. The bone conduction sensor can also contact the human pulse to receive a blood pressure beat signal. In some embodiments, the bone conduction sensor can also be set in an earphone. The audio module 170 can parse out a voice signal based on the vibration signal of the vibrating bone block of the human body obtained by the bone conduction sensor 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 to realize a heart rate detection function.

[0117] The key 190 includes a power key, a volume key, etc. The key may be a mechanical key or a touch key. The mobile phone 100 receives the key input and generates a key signal input related to the user settings and function control of the mobile phone 100.

[0118] Motor 191 can generate vibration prompts. The motor 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. Touch operations acting on different areas of the display screen 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.

[0119] Indicator 192 may be an indicator light, which may be used to indicate charging status, power changes, messages, missed calls, notifications, etc.

[0120] The SIM card interface 195 is used to connect a subscriber identity module (SIM). The SIM card can be connected to and separated from the mobile phone 100 by inserting it into the SIM card interface or pulling it out from the SIM card interface. The mobile phone 100 can support 1 or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface can support Nano SIM cards, MicroSIM cards, SIM cards, etc. Multiple cards can be inserted into the same SIM card interface at the same time. The types of the multiple cards can be the same or different. The SIM card interface can also be compatible with different types of SIM cards. The SIM card interface can also be compatible with external memory cards. The mobile phone 100 interacts with the network through the SIM card to implement functions such as calls and data communications. In some embodiments, the mobile phone 100 uses an eSIM, i.e., an embedded SIM card. The eSIM card can be embedded in the mobile phone 100 and cannot be separated from the mobile phone 100.

[0121] like Figure 3 As shown, the second terminal in the above communication system architecture may be, for example, a wearable device 200. The wearable device 200 may include a power supply 201, a processor 202, a storage module 203, a communication module 204, a radio frequency module 205, an antenna 01, an antenna 02, a microphone 206 (e.g., a bone conduction microphone), a speaker 207, a display screen 208 and other components.

[0122] In some embodiments, the antenna 01 of the wearable device 200 is coupled to the communication module, and the antenna 02 is coupled to the radio frequency module. This allows the wearable device 200 to communicate with the network and other devices through wireless communication technology. The wireless communication technology may include LTE, 5G NR, BT, GNSS, WLAN, NFC, FM, and / or IR technology, etc. Among them, GNSS may include GPS, Global Navigation Satellite System, Beidou Satellite Navigation System, Quasi-Zenith Satellite System and / or Satellite-Based Augmentation System. Thus, the wearable device 200 can obtain the positioning information of the wearable device.

[0123] It is understandable that the wearable device 200 may have Figure 3 More or fewer components may be shown, two or more components may be combined, or there may be a different configuration of components. Figure 3 The various components shown in the drawings may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing or application specific integrated circuits.

[0124] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art can appreciate that with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0125] The technical solution in the embodiment of the present application will be described below in conjunction with the drawings in the embodiment of the present application. Among them, in the description of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a kind of association relationship describing the associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the present application, unless otherwise specified, "at least one" means one or more, and "multiple" means two or more than two. In addition, in order to facilitate the clear description of the technical solution of the embodiment of the present application, in the embodiment of the present application, the words "first", "second" and the like are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit them to be necessarily different.

[0126] It should be noted that in the embodiments of the present invention, the terms “of”, “corresponding”, “relevant” and “corresponding” can sometimes be used interchangeably. It should be pointed out that when the distinction between them is not emphasized, the meanings they intend to express are consistent.

[0127] The message names between the devices or the names of the parameters in the messages in the following embodiments of the present application are merely examples, and other names may be used in specific implementations, which are not specifically limited in the embodiments of the present application.

[0128] For ease of understanding, the positioning method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0129] like Figure 4 As shown, the embodiment of the present application provides a positioning method, which is described by taking the first device as a mobile phone and the second device as a target device (i.e., a device to be located or tracked, such as a wearable device) as an example, including:

[0130] 401. A first device determines a first distance between the first device and a second device.

[0131] For example, when a user wants to locate or track a target device through a mobile phone, Figure 5As shown, the user can click on the icon 502 of the positioning APP of the mobile phone on the desktop 501 of the mobile phone. When the mobile phone detects that the user clicks on the icon 502 of the positioning APP on the desktop 501, the positioning APP can be started and the display as shown in FIG. Figure 6 The graphical user interface (GUI) shown in FIG. 6 is referred to as a positioning interface 601. The positioning interface 601 can display a map of the area (e.g., a district, city, or province, etc.) where the mobile phone is located. The positioning interface 601 can also include a control 602 for indicating a target device, a control 603 for enlarging the display level of the current location, and a control 604 for reducing the display level of the current location, etc.

[0132] Optionally, the user can locate or track the target device through the positioning applet in other APPs of the mobile phone (for example, WeChat APP), which is not limited in this application.

[0133] When the mobile phone detects that the user clicks on the control 602 of the target device, the mobile phone displays the following Figure 7 The GUI shown in the figure can be called the setting interface 605 of the target device. The user can select the wearable device (1A) as the target device by clicking the selection button 606 and setting the selection button 606 on the right. The mobile phone can also use the last selected target device as the default target device (for example, when the user exits the positioning APP and enters the setting interface 605 of the positioning target device next time, the selection button 606 is set on the right by default).

[0134] Optionally, the user can add a new target device in the target device setting interface 605. For example, a new target device can be added by Bluetooth pairing, mobile phone number search, or WeChat friend search, which is not limited in this application. It is understandable that the user can select multiple target devices to be located at the same time. If the mobile phone determines that the user selects multiple target devices to be located at the same time, the mobile phone can display the locations of multiple target devices at the same time. The following description takes the number of target devices as one.

[0135] When the mobile phone determines that the user has selected the target device, it can send a positioning request to the cloud server. The positioning request is used to request the current location of the target device. After the cloud service receives the positioning request from the mobile phone, it notifies the target device to locate and send (report) the location information to the cloud server. After the target device receives the notification sent by the cloud server, it turns on the positioning function and sends the location (information) obtained by positioning to the cloud server. The cloud server forwards the location information to the mobile phone. The mobile phone receives the location information of the target device. At the same time, the mobile phone can turn on the positioning function to obtain its own location information. The mobile phone determines the first distance between the mobile phone and the target device based on the location information of the target device and its own location information.

[0136] When the first device determines that the first distance is greater than or equal to the first threshold, steps 402-406 are performed; when the first device determines that the first distance is less than the second threshold, steps 407 and 411 are performed. The second threshold is less than or equal to the first threshold.

[0137] 402. When the first distance is greater than or equal to a first threshold, the first device sends first indication information to the second device, where the first indication information is used to instruct the second device to adopt a first positioning method.

[0138] Among them, the positioning accuracy of the first positioning method is relatively low. For example, the first positioning method can be a positioning method based on base station positioning or a positioning method based on IP address positioning. The positioning frequency of the first positioning method can be set to be relatively low (for example, 60s / time) to save power consumption. The positioning frequency of the first positioning method can be a system default or can be set by the user.

[0139] For example, Figure 7 As shown, the user can click control 607 in the setting interface 605 of the target device, such as Figure 8 As shown, after the mobile phone detects that the user clicks the control 607, the mobile phone can display the target device positioning mode setting interface 801. Among them, the control 802 indicates that the first distance is greater than the first threshold (for example, the first threshold is 1km), and the control 803 indicates that when the first distance is greater than the first threshold, the first positioning mode (for example, base station positioning) is adopted. The control 804 indicates the positioning accuracy of the first positioning mode (for example, it can be 100m), and the control 805 indicates the positioning frequency of the first positioning mode (for example, it can be 60s / time).

[0140] like Fig. 9 As shown in (a) of FIG. 8 , after the user clicks the control 802, the mobile phone can display a (drop-down) list control 806, and the user can reset (select) the first threshold. Fig. 9 As shown in (b) of FIG. 8 , after the user clicks the control 804, the mobile phone can display (pull-down) a list control 807, and the user can reset (select) the positioning accuracy of the first positioning method. Fig. 9 As shown in (c) in FIG. 8 , after the user clicks the control 805 , the mobile phone may display (pull-down) a list control 808 , and the user may reset (select) the positioning frequency of the first positioning method.

[0141] 403. The second device receives the first indication information sent by the first device.

[0142] The second device may receive the first indication information through the cloud server, that is, the second device may receive the first indication information forwarded by the cloud server.

[0143] 404. The second device adopts the first positioning method and sends first positioning information obtained by adopting the first positioning method to the first device.

[0144] The first positioning information is used to indicate the first position of the second device.

[0145] 405. The first device receives first positioning information obtained by the second device using the first positioning method.

[0146] The first device may receive the first positioning information through the cloud server, that is, the first device may receive the first positioning information forwarded by the cloud server.

[0147] 406. The first device displays the first position of the second device in a first display manner based on the first positioning information.

[0148] Among them, the first display mode can be a low-precision display mode, that is, the error range of the position of the second device displayed by the first display mode is relatively large. For example, a geometric figure can be used to represent the first position of the second device, and the error range of the first position of the second device is within 100m (meters). Of course, the error range of the first position of the second device can also be 50m, 200m or 300m, etc., which is not limited in this application. Among them, the geometric figure can be a circle, an ellipse, a polygon, a sector or an arc, etc.

[0149] For example, if Fig.10 As shown, the mobile phone can display the icon 701 of the target device, the location of the target device (the location of the target device can be represented by a circle 702) and the current positioning mode 703 of the target device in the positioning interface 601. Among them, the current positioning mode of the target device can be the first positioning mode (for example, base station positioning); the positioning accuracy can be 100m (within), that is, the error range of the location represented by the circle 702 is within 100m; the positioning frequency can be 60 seconds (s) / time. The mobile phone can also display the icon 704 of the mobile phone user and the location of the mobile phone. The location of the mobile phone can be displayed as a precise point or a circle ( Fig.10 Of course, the mobile phone may not display the icon 704 of the mobile phone user, and this application does not limit this.

[0150] In a possible design, after the first device displays the first position of the second device in a first display mode based on the first positioning information, the first device receives a first operation of the user on the position of the second device. In response to the first operation, the first device displays the position of the second device in a second display mode, and the display accuracy of the second display mode is greater than the display accuracy of the first display mode.

[0151] For example, Fig.11As shown, the user can click on the icon 701 or circle 702 of the target device, and the mobile phone can display a function list control 706. The function list control 706 may include a precise positioning control 707. The user can click on the precise positioning control 707, and after the mobile phone detects that the user clicks on the precise positioning control 707, the mobile phone can notify the target device to use the second positioning method, and the mobile phone receives the positioning information obtained by the target device in the second positioning method, and then the mobile phone displays the location of the target device in the second display method. Fig.11a As shown in (a) in FIG. 1 , a smaller geometric figure (e.g., a smaller circle 7021) may be used to represent the position of the target device, and the error range of the position represented by the circle 7021 is within 50 m; or Fig.11a As shown in (b) of FIG. 7 , a point 7022 can be used to represent the position of the target device, and the error range of the position represented by the point 7022 can be within 5 meters. The positioning frequency of the second positioning method can remain unchanged.

[0152] Optional, such as Fig.11 As shown, the function list control 706 may also include a distance control 708, a movement speed control 709, a movement direction control 710, a history track control 711, and a route control 712. When the user clicks the distance control 708, as shown in FIG. Fig.11b As shown in (a) of FIG. 7 , the mobile phone can display the real-time distance 713 between the mobile phone and the target device. When the user clicks the motion speed control 709, as shown in FIG. Fig.11b As shown in (b) of FIG. 7 , the mobile phone can display the real-time motion speed 714 of the target device. When the user clicks the motion direction control 710, as shown in FIG. Fig.11b As shown in (c) of FIG. 1 , the mobile phone can display the real-time movement direction 715 of the target device (for example, the real-time movement direction can be indicated by an arrow or a triangle, which is not limited in this application). When the user clicks the history track control 711, as shown in FIG. Fig.11b As shown in (d) in FIG. 1 , the mobile phone can display the historical trajectory 716 of the target device (wherein the circle 717 can represent the location of the target device obtained by the mobile phone for the first time). When the user clicks the route control 712, the mobile phone can display preferred travel plans of different travel modes from "my location" (the location of the mobile phone) to "the location of the target device" (for example, a bus travel plan (such as Fig.11c as shown), cycling (shared bicycle) travel plan, taxi travel plan, self-driving travel plan or walking travel plan, etc.).

[0153] Optionally, each time the mobile phone receives the positioning information sent by the target device according to the positioning frequency of the first positioning method, it can vibrate, emit a prompt sound, flash a breathing light, or actively light up the screen to remind the user that the location of the target device has been updated. At the same time, the mobile phone updates the location of the target device in the positioning interface 601.

[0154] 407. When the first distance is less than the second threshold, the first device sends second indication information to the second device, where the second indication information is used to instruct the second device to adopt a second positioning method.

[0155] The second positioning method has a higher positioning accuracy. For example, the second positioning method can be satellite positioning, Wifi positioning, Bluetooth positioning, sensor inertial positioning, and other positioning methods. The positioning frequency of the second positioning method can be set higher (for example, 10s / time) to accurately locate the target device. The positioning frequency of the second positioning method can be a system default or set by the user. The process of the user setting the second positioning method can refer to step 402, which will not be repeated here.

[0156] It should be noted that the positioning accuracy of the first positioning method is less than the positioning accuracy of the second positioning method. The positioning frequency of the first positioning method is the same as or different from the positioning frequency of the second positioning method. Optionally, the positioning frequency of the first positioning method may be less than the positioning frequency of the second positioning method.

[0157] In a possible design, if the second threshold is less than the first threshold, when the first distance is less than the first threshold and greater than the second threshold, the first device sends a third indication message to the second device, and the third indication message is used to instruct the second device to adopt a third positioning method. The positioning accuracy of the third positioning method is the same as that of the first positioning method, and the positioning frequency of the third positioning method is greater than that of the first positioning method; or, the positioning accuracy of the third positioning method is the same as that of the second positioning method, and the positioning frequency of the third positioning method is less than that of the second positioning method.

[0158] 408. The second device receives the second indication information sent by the first device.

[0159] The second device may receive the second indication information through the cloud server, that is, the second device may receive the second indication information forwarded by the cloud server.

[0160] 409. The second device adopts a second positioning method and sends second positioning information obtained by adopting the second positioning method to the first device.

[0161] The second positioning information is used to indicate the second position of the second device.

[0162] 410. The first device receives second positioning information obtained by the second device using a second positioning method.

[0163] The first device may receive the second positioning information through the cloud server, that is, the first device may receive the second positioning information forwarded by the cloud server.

[0164] 411. The first device displays the second position of the second device in a second display manner based on the second positioning information.

[0165] It should be noted that the display accuracy of the second display mode is greater than that of the first display mode, that is, the error range of the position of the second device displayed by the second display mode is smaller than the error range of the position of the second device displayed by the first display mode. For example, a smaller geometric figure (compared with the geometric figure corresponding to the first display mode) can be used to represent the first position of the second device, or a point can be used to represent the first position of the second device, and the error range of the first position of the second device is within 5m (or 1m, 2m, 3m, etc.).

[0166] like Fig.12 As shown, the mobile phone can display the icon 701 of the target device, the location of the target device (the location of the target device can be represented by a dot 705) and the current positioning mode 703 of the target device in the positioning interface 601. Among them, the current positioning mode of the target device can be the second positioning mode (for example, GPS positioning mode), and its positioning accuracy can be 5m, that is, the error range of the location represented by the dot 104 is within 5m, and the positioning frequency can be 10s / time. The mobile phone can also display the icon 704 of the mobile phone user and the location of the mobile phone. The location of the mobile phone can be displayed as a precise dot or a circle ( Fig.12 Of course, the mobile phone may not display the icon 704 of the mobile phone user, and this application does not limit this.

[0167] Based on the above technical solution, when the first distance between the first device and the second device is greater than or equal to the first threshold, the first device sends a first indication message to the second device to instruct the second device to adopt the first positioning method; when the first distance is less than the second threshold (the second threshold is less than or equal to the first threshold), the first device sends a second indication message to the second device to instruct the second device to adopt the second positioning method; wherein the positioning accuracy of the first positioning method is less than the positioning accuracy of the second positioning method. In this way, the second terminal device can be prevented from always adopting a high-precision positioning method, and the power consumption of the terminal can be reduced during the positioning process, thereby reducing the possibility of the terminal shutting down.

[0168] The positioning method provided by the embodiment of the present application is introduced below in combination with the application scenarios and beneficial effects of the embodiment of the present application.

[0169] Scenario 1: An owner tracks a pet wearing a device with a positioning function (eg, a pet positioning collar with a positioning function).

[0170] When playing outdoors, if a pet dog wearing a pet collar with a positioning function gets lost, the owner can locate the pet dog on the positioning APP on the mobile phone. The processing logic is as follows:

[0171] Assume that the second threshold is less than the first threshold, the first threshold is 1 km, and the second threshold is 500 meters. When the mobile phone positioning APP determines that the distance between the dog and the owner is greater than or equal to 1 km, Fig.13 As shown in (a) of FIG. 1 , the mobile phone (owner, represented by icon 704) can remotely instruct the positioning collar (pet dog, represented by icon 701) to adopt the first positioning method (for example, base station positioning method, positioning accuracy is 100m), and report the location information every 60s. When the positioning APP of the mobile phone determines that the distance between the dog and the owner is less than 1 km and greater than 500 meters, Fig.13 As shown in (b) in the figure, the mobile phone can remotely instruct the positioning collar to use the third positioning method. The positioning accuracy of the third positioning method is the same as that of the first positioning method (for example, the base station positioning method has a positioning accuracy of 100m), and the positioning frequency of the third positioning method is greater than the positioning frequency of the first positioning method (for example, reporting location information every 30s). Alternatively, when the positioning APP of the mobile phone determines that the distance between the dog and the owner is less than 1 km and greater than 500 meters, as Fig.13 As shown in (c) in the figure, the mobile phone can remotely instruct the positioning collar to use the third positioning method. The positioning accuracy of the third positioning method is the same as that of the second positioning method (for example, the GPS positioning method has a positioning accuracy of 5m), and the positioning frequency of the third positioning method is lower than that of the first positioning method (for example, reporting location information every 40s). When the positioning APP of the mobile phone determines that the distance between the dog and the owner is less than 500 meters, Fig.13 As shown in (d), the mobile phone can remotely instruct the positioning collar to adopt a second positioning method (for example, GPS positioning method with a positioning accuracy of 5m) and report the location information every 10s.

[0172] In this way, the working time of the positioning collar can be avoided by excessive pursuit of positioning accuracy and positioning frequency, which can help the owner find the pet as soon as possible and avoid the positioning collar being turned off, making the owner unable to find the pet.

[0173] Scenario 2: User 1 and User 2 share their location via WeChat.

[0174] Assume that user 1 and user 2 are WeChat friends, and both are online. User 1 initiates location sharing to the smartwatch worn by user 2 through WeChat on the mobile phone, and user 2 agrees to location sharing on the smartwatch. If the first threshold is 1 km, and the second threshold is equal to the first threshold, when the mobile phone determines that the distance between user 1 and user 2 is greater than or equal to 1 km, Fig.10As shown, the mobile phone (user 1, represented by icon 704) can remotely instruct the smart watch (user 2, represented by icon 701) to adopt the first positioning method (for example, base station positioning method, positioning accuracy is 100m) and report the location information every 60s. When the mobile phone determines that the distance between user 1 and user 2 is less than 1 km, Fig.12 As shown, the mobile phone can remotely instruct the smart watch to use the second positioning method (for example, GPS positioning method, positioning accuracy is 5m), and report the location information every 10 seconds. In addition, the mobile phone can send the location information of the mobile phone to the smart watch (for example, the mobile phone can send the location information to the smart watch every 60 seconds, every 20 seconds, or every 10 seconds) so that both parties can share the location. In addition, the positioning method of the mobile phone can be the same as or different from the positioning method of the smart watch (for example, when the smart watch adopts the first positioning method, the mobile phone can adopt the first positioning method or the second positioning method for positioning).

[0175] In this way, compared with using high-precision positioning methods to locate the target terminal multiple times, which increases the power consumption of the target terminal, adjusting the positioning accuracy and positioning frequency according to the distance can save the positioning power consumption of mobile phones and smart watches while getting as close to the target device as possible, and try to avoid automatic shutdown of mobile phones and smart watches (for example, in the scenario of looking for (lost) elderly people or children wearing devices with positioning functions (for example, wearable devices), it is particularly important to get as close to the target as possible and ensure that the target device does not shut down automatically).
