Detailed ways

First, for ease of understanding, the following introduces related terms and concepts that may be involved in the embodiments of the present application.

1. Global Navigation Satellite System

GNSS generally refers to all satellite navigation systems, such as Global Positioning System (GPS), Glonass Satellite Navigation System, Galileo Satellite Navigation System, Beidou Navigation Satellite System (BDS), etc. , and also includes other satellite navigation systems under construction and to be constructed in the future. The Global Navigation Satellite System is a star-rated radio navigation system that uses artificial satellites as navigation stations. It can provide all-weather, high-precision position, speed and time information for various military and civilian carriers on land, sea, air and space around the world.

Among them, the Beidou satellite navigation system has short message communication capabilities, that is to say, terminal equipment can use Beidou chips to send message information to satellites and receive message information from satellites.

2. Internet of Things (IoT)

The Internet of Things can be understood as: a network that connects any item to the Internet according to the agreed protocol for information exchange and communication to achieve intelligent identification, positioning, tracking, monitoring and management.

The current communication technologies used in the Internet of Things include wired communication technologies and wireless communication technologies. Among them, the wireless communication technologies that can be used in the Internet of Things include: Wi-Fi, Zigbee, Z-Wave, long range radio (LoRa), narrow band Internet of things (NB- IoT), 2nd generation (2nd generation, 2G) mobile communication protocol, 3rd generation (3rd generation, 3G) mobile communication protocol, 4th generation (4th generation, 4G) mobile communication protocol, 5th generation (5th generation, 5G) ) mobile communication protocol, and future communication protocols, such as the sixth generation (6th generation, 6G) mobile communication protocol, etc.

The mobile phone can use GPS positioning, Wi-Fi positioning and other positioning methods to obtain its own location information, which can be the real-time location information of the mobile phone. The phone can also share location information over cellular or Wi-Fi. For example, send the location information to the cloud server. Like this, when mobile phone is lost, user can utilize computer or any networked device to log in cloud server, inquire about the location information of this mobile phone. For example, after the user logs into the cloud server, he can obtain the location of the mobile phone as shown in Figure 1, thereby determining that the location of the mobile phone is located at "A", the update time of this location is "just now", and the status of the mobile phone can be "online" (that is, the mobile phone powered on and connected to the Internet), the user can find the mobile phone as soon as possible based on this information.

However, if the mobile phone is offline, the mobile phone cannot send location information to the cloud server, so that the user cannot remotely query the location information of the mobile phone, thereby failing to realize the function of retrieving the mobile phone. For example, when the mobile phone is offline, even if the user logs in to the cloud server, he can only obtain the location map of the offline mobile phone as shown in Figure 2. He can only query the location of the mobile phone before it was offline at "B", and the time when the mobile phone was offline is "B". November 11, 2018". Wherein, the mobile phone offline may include that the mobile phone is turned off or the mobile phone is turned on and not connected to a network (such as a cellular network or Wi-Fi). Wherein, the mobile phone is turned on and not connected to the network may include: the mobile phone is set to airplane mode, the mobile phone is located outside the network coverage area, and the positioning-related communication modules (such as cellular communication module and Wi-Fi module) in the mobile phone are turned off, etc.

Based on the description of the above-mentioned device retrieval function, it can be seen that the current positioning method of terminal devices has the following problems: if the terminal device is turned off, the terminal device cannot locate and share location information, resulting in the user being unable to query the location of the terminal device, and it is also impossible to realize the terminal Device retrieval function. If the terminal device is turned on and not connected to the cellular network or Wi-Fi, although the terminal device can be positioned, it cannot share the location, so that the user cannot query the location of the terminal device, and the function of retrieving the terminal device cannot be realized. Therefore, current terminal devices have many restrictions on locating and sharing locations, resulting in relatively large limitations in the positioning capabilities of terminal devices.

In order to solve the problems existing in the positioning means of the terminal equipment, the embodiment of the present application provides a terminal equipment, a positioning method and a device, so as to reduce the limitation of the terminal equipment in positioning and sharing the location, and improve the positioning capability of the terminal equipment.

Please refer to Figure 5, the terminal equipment includes: a Bluetooth module, a Wi-Fi module, a satellite positioning module, an Internet of Things module and a battery. There is an electrical connection among the Bluetooth module, the Wi-Fi module, the satellite positioning module, the Internet of Things module and the battery. For example, the Bluetooth module, the Wi-Fi module, the satellite positioning module, the Internet of Things module and the battery can be connected through a bus.

Wherein, the battery is used to supply power to the Bluetooth module, the Wi-Fi module, the satellite positioning module and the Internet of Things module when the terminal device is turned on or off. The satellite positioning module can be connected to the Beidou network. For example, the satellite positioning module includes a Beidou satellite navigation system positioning module, and the satellite positioning module can be connected to the Beidou network through the Beidou satellite navigation system positioning module.

Wherein, the SOC 610, the NC module 620 and the IoT module 630 may all include a universal asynchronous receiver/transmitter (UART) interface and a general purpose input output (GPIO) interface. The UART interface is a universal serial data bus used for asynchronous communication. The bus is a bidirectional communication bus, which can convert the data to be transmitted between serial communication and parallel communication. The UART interface can be used to connect two different modules, for example: SOC610 communicates with the NC module 620 through the UART interface. The GPIO interface can be configured through software. Specifically, the GPIO interface can send and receive control signals and also send and receive data signals. The GPIO interface can be used to connect two different modules, for example: SOC610 communicates with the NC module 620 through the GPIO interface.

Optionally, the embodiment of the present application also provides another mobile phone structure, and FIG. 7 is a schematic structural diagram of the mobile phone provided in the embodiment of the present application III. Please refer to Fig. 7, the difference between Fig. 7 and Fig. 6 is: in Fig. 7, no matter whether the mobile phone is turned on or off, the NC module 620 is coupled with the battery 660 instead of the PMU 640, and the clock interface of the NC module 620 is connected to the The clock interface of the IoT module 630 is coupled. In Fig. 6, when the mobile phone is turned on, the NC module 620 is coupled with the PMU640, and the clock interface of the NC module 620 is coupled with the clock interface of the PMU640; The clock interface of the networking module 630 is coupled.

It can be understood that the mobile phone 600 shown in FIG. 7 can also realize that the battery 660 can still supply power to the NC module 620 when the mobile phone is turned off. Wherein, the mobile phone 600 shown in Figure 7 is compared with the mobile phone 600 shown in Figure 6, because the PMU640 can adjust the output power consumption according to the operating state of the NC module 620, thus for the mobile phone shown in Figure 6, the NC module 620 is coupled with the PMU640 And when the NC module 620 is not working, the PMU 640 can reduce the output power to the NC module 620, thereby saving power.

It can be understood that, the structure shown in the embodiment of the present invention does not constitute a specific limitation on the mobile phone 600 . In other embodiments of the present application, the mobile phone 600 may include more or fewer components than shown in the figure, or combine certain components, or separate certain components, or arrange different components. The illustrated components can be realized in hardware, software or a combination of software and hardware.

The above-mentioned Figures 4-7 illustrate the structure of the terminal equipment in the positioning system by taking the mobile phone 600 as an example. The following describes the positioning method provided by the embodiment of the present application in conjunction with Figures 8-19.

The positioning method provided in the embodiment of the present application may be applied to a terminal device in the positioning system shown in FIG. 3 . Taking the mobile phone shown in FIG. 6 as the terminal device and the notebook computer as the positioning receiving device as an example, the positioning method provided by the embodiment of the present application will be described below.

The mobile phone and the laptop can log in to the same account (such as a Huawei account), and interact through the cloud server corresponding to the account. For example, the mobile phone can send real-time location information to the cloud server corresponding to the account, and the laptop can log in to the cloud server corresponding to the account. The cloud server obtains the real-time location information.

In the embodiment of the present application, when the mobile phone is turned off or not connected to the above-mentioned first network, the mobile phone can obtain real-time location information, and send the real-time location information to the second network, and then the second network forwards the real-time location information to the cloud server. Exemplarily, in conjunction with the above-mentioned Figure 6, it can be seen that when the mobile phone is turned off or not connected to the above-mentioned first network, the mobile phone can use the NC module to obtain real-time location information, and can use the Internet of Things module or the Beidou satellite navigation system positioning module to connect to the second Network, send the location information to the cloud server through the Internet of Things module or the Beidou satellite navigation system positioning module, and the laptop can access the cloud server to obtain the location information of the mobile phone.

Optionally, the acquisition of real-time location information by the mobile phone may be triggered by a cloud server. Exemplarily, the cloud server may send a positioning request to the second network, and the second network forwards the positioning request to the mobile phone. Among them, the cloud server can send a positioning request to the mobile phone according to the network conditions of the Internet of Things and Beidou. For example, when the Internet of Things network is unobstructed, the cloud server sends a positioning request to the mobile phone through the Internet of Things; Beidou sends a positioning request to the mobile phone. Of course, the cloud server can send the positioning request to the mobile phone through the Internet of Things and send the positioning request to the mobile phone through the Beidou network, which is not limited in this application. When the mobile phone receives the positioning request, it can obtain real-time location information according to the positioning request, and send the real-time location information to the second network, and then the second network forwards the real-time location information to the cloud server. Of course, when no positioning request is received from the cloud server, the mobile phone can also obtain real-time location information, and send the real-time location information to the cloud server through the second network. For example, the mobile phone can acquire real-time location information every hour, and send the real-time location information to the cloud server through the second network.

If the user needs to obtain the real-time location information of the mobile phone, the user can use a laptop computer to log in to the cloud server to obtain the real-time location information of the mobile phone. Exemplarily, after the notebook computer logs into the cloud server, please refer to FIG. 8 , the user can operate the touchpad or mouse (not shown in the figure) of the notebook computer, and click the "locate" button displayed on the display screen of the notebook computer. The notebook computer can respond to the operation of the user, and send a request for acquiring location information to the cloud server. The cloud server can feed back the real-time location information of the mobile phone to the laptop according to the location information acquisition request. In addition, when the cloud server does not receive a location information acquisition request, the cloud server can also feed back the location information of the mobile phone to the laptop. In this way, when the user has just logged in to the cloud server and has not clicked the "location" button, the cloud server can immediately send the location information to the user. Feedback the location information of the mobile phone and reduce user operations, thereby improving user experience and improving positioning efficiency.

Wherein, since the mobile phone can periodically feed back real-time location information to the cloud server through the second network, that is, the cloud server stores multiple pieces of location information of the mobile phone. Therefore, when feeding back the real-time location information of the mobile phone to the notebook computer, the cloud server can feed back the location information whose feedback time is closest to the current time among the plurality of location information to the notebook computer. For example, assume that the cloud server stores four location information of the mobile phone, A (feedback time 7:00), B (feedback time 8:00), C (feedback time 9:00), D (feedback time 10:00), The current time is 10:30, then the cloud server can feed back D to the notebook computer, and can also feed back the historical location track information and corresponding time information of the mobile phone, for example including at least the following positions and the location track information of the corresponding time: A (feedback time 7:00) → B (feedback time 8:00) → C (feedback time 9:00) → D (feedback time 10:00).

In addition, when receiving the location information acquisition request, the cloud server can send a positioning request to the mobile phone through the second network, so as to obtain the real-time location information of the mobile phone. Then, the cloud server can obtain the real-time location information, and the laptop computer can access the cloud server to view the location information. In this way, the user can obtain the real-time location information of the mobile phone and improve the positioning accuracy. If the historical location information of the mobile phone is also stored in the cloud server, the notebook computer can access the cloud server to view the historical location information of the mobile phone. In this way, the historical location information of the mobile phone can be provided to the user, which facilitates the user to determine the past location of the mobile phone and improves user experience.

The above positioning implementation manner will be further described below in conjunction with specific application scenarios.

Take the interaction between the cloud server and the mobile phone through the Beidou network as an example. Please refer to Figure 9. Xiaoxi is traveling in the forest. In some scenarios, there may be no cellular network and Wi-Fi in the forest. Xiaoxi’s mobile phone can communicate with the Beidou satellite navigation system positioning module. The Beidou satellite interacts to connect to the Beidou network. Xiaodong connects to the cloud server through a laptop in an environment with a cellular network. The cloud service can be connected to the Beidou network through the Internet. For example, the cloud server can interact with the Beidou server in the Beidou network through the Internet, thereby connecting to the Beidou network. When Xiaoxi's mobile phone is turned off or not connected to the first network, Xiaoxi's mobile phone can periodically obtain real-time location information, and send the real-time location information to the cloud server through the Beidou network. If Xiaodong wants to know Xiaoxi's location in the forest, Xiaodong can use his laptop to log in to the cloud server. After Xiaodong's laptop logs into the cloud server, the laptop can display the interface shown in Figure 8. Xiaodong can locate Xiaoxi through the cloud server by clicking the "locate" button. Among them, Xiaodong's laptop can obtain the latest location information fed back by Xiaoxi's mobile phone through the cloud server. Alternatively, the cloud server can send a positioning request to Xiaoxi's mobile phone through Beidou to obtain the real-time location information of Xiaoxi's mobile phone, and then Xiaodong's laptop can obtain the real-time location information through the cloud server. After Xiaodong's laptop receives Xiaoxi's location information, it can display the positioning map shown in Figure 10 on the display screen, so that Xiaodong can obtain Xiaoxi's location (longitude is a, latitude is b). When Xiaoxi's mobile phone is turned off or not connected to the first network, the NC module in Xiaoxi's mobile phone is still powered, and the Beidou satellite navigation system positioning module in the NC module can work, so Xiaoxi's mobile phone can still use the Beidou satellite navigation system for positioning The module obtains location information and connects to the Beidou network. Therefore, even if Xiaoxi's mobile phone cannot connect to the cellular network or Wi-Fi, or even Xiaoxi's mobile phone is turned off, Xiaodong can use his laptop to log in to the cloud server and query Xiaoxi's location.

In some possible embodiments, the laptop computer can access the cloud server to obtain a historical track including real-time location information and historical location information of the mobile phone, and send the historical track to the laptop computer. Assuming that the historical location information of the mobile phone includes: G, F, D, B in chronological order, and the real-time location information of the mobile phone is A, then the cloud server can generate the historical track "G→F→D→B→ A" and presented to the user by the laptop. In this way, the user can intuitively determine the movement track of the mobile phone, thereby improving user experience.

In addition, if the mobile phone is turned on and is not connected to the first network but connected to the second network, one or more of the following control operations can be performed on the mobile phone through the cloud server and the second network: reduce the brightness of the display screen, enter the airplane mode, reduce the frequency, or power off. In this way, the power consumption of the mobile phone can be reduced and the battery power of the mobile phone can be saved.

Based on the implementation of the above positioning method, it can be known that even if the mobile phone is turned off or not connected to the first network, the cloud server can interact with the mobile phone through the second network. Therefore, in some possible embodiments, the cloud server can communicate with the mobile phone through the second network. Realize one or more of the following interactive operations: sending information to the mobile phone, requesting feedback information from the mobile phone, or controlling the operation of the mobile phone. In this way, even if the mobile phone is turned off or not connected to the first network, the user can also use the laptop to log in to the cloud server to remotely control the mobile phone, which is convenient for the user to communicate with the owner of the mobile phone and obtain the data of the mobile phone (such as voice, photos, etc. stored in the mobile phone). video, etc.) and protect user privacy.

For example, please refer to the above Figure 10 again, the "photograph" button can realize the function of controlling the camera of the mobile phone to take pictures and feed back the photos to the cloud server, and the "recording" button can control the microphone of the mobile phone to record sound and feed back the sound to the cloud server The "send message" button can realize the function of sending information to the mobile phone (such as text information, picture information, etc. entered by the user), and the "erase data" button can realize the control of the mobile phone to erase data (such as photos and videos on the mobile phone) , account information, etc.).

Wherein, the implementation of the function of the "photograph" button can be as follows: the notebook computer responds to the user's operation of clicking the "photograph" button, and sends a first photograph request to the cloud server, and the first photograph request instructs the mobile phone to photograph and return the photographed photograph. The cloud server sends a second photographing request to the mobile phone through the second network according to the first photographing request, and the second photographing request indicates feedback of photographed photographs. The mobile phone controls the camera to take photos according to the second photo taking request and feeds back the photos to the cloud server. The cloud server sends the photo to the laptop. By analogy, the implementation of buttons such as "Record", "Send Message", and "Erase Data" can refer to the implementation of the above-mentioned "Photograph" button, and will not be repeated here.

In some possible embodiments, the format of the above location information may include one or more of the following: text (such as the text representing the latitude and longitude), pictures (such as the positioning map shown in Figure 11 above), voice (such as the text representing the latitude and longitude), voice), or video (such as positioning video that characterizes the location of a mobile phone). In this way, the location information can be displayed to the user in various formats, thereby improving user experience.

In the above-mentioned positioning implementation, since the satellite positioning module, Wi-Fi module, or Bluetooth module included in the NC module in the mobile phone shown in Figure 6 can all be used to obtain real-time location information, the Internet of Things module in the mobile phone and Beidou The positioning module of the satellite navigation system can be connected to the Internet of Things and the Beidou network respectively, so that it can send real-time location information to the cloud server. Therefore, there are many positioning implementation manners for the mobile phone to use the positioning module to acquire real-time location information and send the real-time location information to the cloud server.

In some positioning implementations, the satellite positioning module in the NC module can be used to obtain real-time location information used to characterize the location of the mobile phone, and the real-time location information can be sent to the cloud server by using the Internet of Things module (hereinafter, the positioning implementations are collectively referred to as positioning way 1). Positioning method 1 is suitable for application scenarios with satellite positioning signals and the Internet of Things, such as streets, roads, parks, amusement parks, sports fields, scenic spots, squares and other areas where the sky is not blocked by objects and has Internet of Things. For example, please refer to the outdoor scene shown in FIG. 12 , the mobile phone can use the satellite positioning module to receive the positioning signal transmitted by the satellite, and determine the real-time location information of the mobile phone according to the positioning signal. The mobile phone can also use the Internet of Things module to connect with the Internet of Things access device, so as to send real-time location information to the cloud server through the Internet of Things.

Wherein, the locating condition may include: a locating request is received or a terminal device arrives at a locating time. The first positioning instruction is used to instruct to acquire the real-time location information of the mobile phone. It should be noted that the arrival of the terminal device at the positioning time can be understood as the time of the device being the positioning time, or that the device is after the positioning time. The positioning time may include: one or more preset time points, and periodic time points. Example 1, the positioning time may be: January 1, 2020 10:10:10, the positioning time instructs the mobile phone to obtain the real-time location information of the mobile phone at 10:10:10 January 1, 2020.

Of course, the above positioning method 3 can also be executed when the mobile phone is turned on.

It should be noted that, in the above positioning methods shown in FIG. 17 and FIG. 18 , when the positioning server obtains the real-time location information, it may also send the real-time location information to the cloud server. In this way, during the process of executing the positioning method shown in FIG. 17 and FIG. 18, when the positioning server determines the real-time location information of the mobile phone, it can immediately forward the real-time location information to the cloud server, thereby improving the positioning efficiency.

In some positioning implementations, the satellite positioning module can be used to obtain real-time location information used to characterize the location of the mobile phone, and the Beidou satellite navigation system positioning module can be used to send real-time location information to the cloud server (hereinafter, the positioning implementations are collectively referred to as positioning methods 4). Positioning method 4 is suitable for application scenarios with Beidou satellites, such as forests, seas, deserts, mountains, swamps, hills, plateaus and other places where the sky is not blocked by objects and there is no Wi-Fi, no Bluetooth, and no Internet of Things. For example, please refer to the forest scene in Figure 9, the mobile phone can use the Beidou satellite navigation system positioning module to receive the positioning signal transmitted by the Beidou satellite, and determine the real-time location information of the mobile phone according to the positioning signal. The mobile phone can also use the positioning module of the Beidou satellite navigation system to connect to the Beidou satellite, so as to send real-time location information to the cloud server through the Beidou network.

The positioning method 4 is further described below in conjunction with a flow chart, and FIG. 19 is a schematic flow diagram 4 of a positioning method provided in an embodiment of the present application. Please refer to Figure 19, the positioning method 4 may include S1901-S1902:

S1901. When the positioning condition is satisfied, the satellite positioning module acquires real-time position information.

Wherein, the locating condition may include: a locating request is received or a terminal device arrives at a locating time.

It can be understood that the process of acquiring real-time location information by the satellite positioning module can refer to the above S1302, which will not be repeated here.

S1902. The Beidou satellite navigation system positioning module sends real-time location information to the cloud server, and the cloud server receives the real-time location information from the Beidou satellite navigation system positioning module.

For example, since the Beidou satellite navigation system positioning module can interact with Beidou satellites to access the Beidou network, the Beidou satellite navigation system positioning module can send Beidou short messages to the Beidou network, and the short messages can carry real-time location information. Then the Beidou network forwards the real-time location information to the cloud server. It should be noted that, in the implementation example of this application, the Beidou satellite navigation system positioning module can not only send real-time location information to Beidou satellites, but also send text, pictures or voice information to Beidou satellites. For example, when the positioning module of the Beidou satellite navigation system sends a short message carrying real-time location information to the Beidou satellite, it can also carry text information such as "rescue needed" in the short message, or carry mobile phone cameras, microphones and other sensors to obtain pictures and voice messages.

In the embodiment of the present application, in the above-mentioned positioning mode 2 and positioning mode 3, the positioning module of the Beidou satellite navigation system can also be used to share the real-time position. Specifically, referring to the above positioning method 2 and S1902, after the Bluetooth module obtains the real-time location information, the positioning method 2 may further include: the Bluetooth module sends the real-time location information to the Beidou satellite navigation system positioning module. Then, the positioning module of the Beidou satellite navigation system sends real-time position information to the Beidou satellite, and the Beidou satellite receives the position information from the positioning module of the Beidou satellite navigation system. The Beidou satellite can send the location information to the ground station, and the ground station forwards the location information to the cloud server. In this way, it is possible to provide a positioning method that uses the Bluetooth module for positioning and uses the Beidou satellite navigation system positioning module to send real-time position information, thereby increasing the positioning means of the terminal device and improving the positioning capability of the terminal device.

Correspondingly, referring to the above positioning method 3 and S1902, after the Wi-Fi module obtains the real-time location information, the positioning method 2 may further include: the Wi-Fi module sends the real-time location information to the Beidou satellite navigation system positioning module. Then, the positioning module of the Beidou satellite navigation system sends real-time position information to the Beidou satellite, and the Beidou satellite receives the real-time position information from the positioning module of the Beidou satellite navigation system. The Beidou satellite can send the location information to the ground station, and the ground station forwards the location information to the cloud server. In this way, it is possible to provide a positioning method that uses the Wi-Fi module for positioning and uses the Beidou satellite navigation system positioning module to send real-time position information, thereby increasing the positioning means of the terminal device and improving the positioning capability of the terminal device.

In addition, positioning mode 4 can be controlled by the IoT module or SOC. For example, the Internet of Things module controls the positioning of the positioning module of the Beidou satellite navigation system when the positioning condition is met (for example, the mobile phone is turned off). For another example, the SOC controls the positioning of the positioning module of the Beidou satellite navigation system when the positioning condition is met (for example, the mobile phone is turned on), which is not limited in this application. Among them, when the SOC controls the positioning of the Beidou satellite navigation system positioning module, the Beidou satellite navigation system positioning module can send a positioning signal to the SOC, and then the SOC can determine the real-time location information of the mobile phone according to the positioning signal and the Beidou satellite positioning algorithm. When the IoT module controls the positioning of the Beidou satellite navigation system positioning module, the Beidou satellite navigation system positioning module can send a positioning signal to the IoT module, and then the IoT module can determine the real-time location information of the mobile phone according to the positioning signal and the Beidou satellite positioning algorithm . Since the computing power of the IoT module and SOC is higher than that of the positioning module of the Beidou satellite navigation system, the real-time location information of the mobile phone can be determined by the IoT module or SOC, which can reduce the time required for positioning and improve positioning efficiency.

It can be understood that, combined with the positioning method 4 shown in Figure 19 above, when the mobile phone is turned off, the battery can still supply power to the positioning module of the Beidou satellite navigation system, and the positioning module of the Beidou satellite navigation system can obtain real-time location information and send real-time information to the cloud server. location information. Therefore, regardless of whether the mobile phone is turned off or connected to the cellular network or Wi-Fi, the mobile phone can perform positioning and send real-time location information to the cloud server, thereby solving the problem of limitations in the current positioning capabilities of mobile phones and improving the positioning capabilities of mobile phones. Of course, the above positioning method 4 can also be executed when the mobile phone is turned on.

In the embodiment of the present application, when the user remotely inquires about the location information of the terminal device, he usually logs in to the cloud server to inquire, and the cloud server is usually set up in the Internet. Therefore, in the above positioning mode 1-positioning mode 4, the location information sent by the terminal device to the network device (including Beidou satellite and Internet of Things access device) needs to be forwarded to the cloud server. If the terminal device uses the IoT module to send the location information to the IoT, the location information also needs to be forwarded by the IoT to the cloud server in the Internet. If the terminal device uses the positioning module of the Beidou satellite navigation system to send the location information to the Beidou network, the location information also needs to be forwarded by the Beidou network to the cloud server in the Internet. If the terminal device uses the mobile communication module to send the location information to the cellular network, the location information needs to be forwarded by the cellular network to the cloud server in the Internet. Therefore, communication connections can be established between the Internet and the Internet of Things, the cellular network, and the Beidou network, for example, based on an agreed communication protocol. Of course, it is also possible to establish a communication connection between the cellular network and the Internet of Things and the Beidou network, as well as establish a communication connection between the cellular network and the Internet based on the agreed communication protocol.

The implementation process of the above-mentioned positioning mode 1-positioning mode 4 will be further described below in conjunction with specific application scenarios.

Scenario 1: An environment without cellular network, Wi-Fi, Bluetooth, or Internet of Things but with satellite positioning signals, such as forests (please refer to Figure 9), seas, deserts, etc. When the mobile phone is in scene 1, if the mobile phone is turned on, the mobile phone can use the satellite positioning module to obtain real-time location information. However, since there is no cellular network, no Wi-Fi, and no Internet of Things, the mobile phone cannot send real-time location information to the cloud server through the cellular network or Wi-Fi. At this time, the mobile phone can use the Beidou satellite navigation system positioning module to send real-time location information to the Beidou satellite, so that the Beidou satellite will forward the real-time location information to the cloud server. If the mobile phone is turned off, the mobile phone can also use the Beidou satellite navigation system positioning module to obtain real-time location information, and send real-time location information to the Beidou satellite, so that the Beidou satellite will forward the real-time location information to the cloud server. In other words, when the mobile phone is in scene 1, the above positioning method 4 can be implemented to realize positioning and share the real-time location, so that the user can remotely query the real-time location of the mobile phone, thereby realizing the mobile phone retrieval function.
