【Detailed ways】

In order to make the purpose, technical solution and effect of the present application more clear and definite, the present application will be further described in detail below with reference to the accompanying drawings and examples.

The term "and/or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship. In addition, "many" herein means two or more than two.

It can be understood that the method of the present application may include the methods provided by any one of the following method embodiments and any non-conflicting combination of the following method embodiments.

It can be understood that the terminal positioning method described in this application can be performed by a terminal device, and the terminal device can also be referred to as a terminal for short. The positioning status of the terminal device can be divided into waiting for positioning and positioning, and waiting for positioning means that positioning has not been completed. Targeted has been targeted. A terminal device may be any device with processing capability, for example, a mobile phone, a tablet computer, a computer, and the like. The terminal device includes a positioning module for positioning. For example, the positioning module can be a GNSS (Global Navigation Satellite System, Global Navigation Satellite System) module for positioning using GNSS technology.

The terminal device will perform positioning after it is turned on and powered on. The positioning process of the terminal device can be divided into two types: cold start positioning and hot start positioning. Hot start positioning is performed when the following conditions are met at the same time: The location information is known; the current time, almanac, and ephemeris are known; the time since the last shutdown is not more than a certain time, so the ephemeris and other information have not changed. The cold-start positioning refers to the start-up positioning that cannot meet the above conditions at the same time. For example, the terminal device performs positioning for the first time, or the battery is exhausted, resulting in the loss of previous positioning-related information, or after moving beyond a certain distance in the shutdown state, or after the last time. The positioning time exceeds a certain time, etc. When the positioning signal is good, the hot start positioning speed is very fast, and no other auxiliary positioning methods are needed. The terminal device positioning method in this application is used in the cold start positioning process of the terminal device, and the purpose is to speed up the cold start positioning speed of the terminal device .

Please refer to FIG. 1. FIG. 1 is a schematic flow diagram of an embodiment of the terminal positioning method of the present application. The terminal positioning method in this embodiment is performed by the terminal to be positioned. The terminal positioning method includes:

Step S110: if the positioning is not completed within the first time period, broadcast a positioning assistance request.

Wherein, the positioning assistance request is used to request to obtain positioning assistance data, and the positioning assistance data may be positioning related data needed in the positioning process, and the content of the positioning related data depends on the type of positioning technology. For example, the terminal to be positioned can use GNSS technology for positioning, and the corresponding positioning assistance data can be A-GNSS (Assisted GNSS, assisted GNSS technology) data, that is, assisted global navigation satellite system data. Correspondingly, the positioning assistance data can include ephemeris information, etc.

In this embodiment, positioning using GNSS technology is taken as an example for illustration. The positioning-related data may be obtained by the terminal from satellite positioning signals during the positioning process, or may be downloaded by the terminal in the form of positioning assistance data. The speed at which the terminal obtains positioning-related data from satellite positioning signals is slower than that of directly downloading positioning assistance data, so downloading positioning assistance data can effectively speed up terminal positioning.

It can be understood that the terminal can download positioning assistance data from the server by connecting to the public network. The public network mentioned here is the public communication network, which is a communication network built by network service providers and used by public users. The terminal can also By connecting to a private network, the positioning assistance data is obtained from the base station. The private network mentioned here is a private network, which is to achieve network signal coverage in a specific area and provide communication services for specific users in the links of organization, command, management, production, and scheduling. A professional network, for example, can be a private network used by the user's company. However, if the user connects to the private network to obtain positioning assistance data, the download process will affect the communication of the terminal. Therefore, it is generally not used to connect to the private network to obtain positioning assistance data. In some cases, the terminal to be positioned cannot download the positioning assistance data, for example, cannot connect to the public network, and at this time the terminal cannot use the positioning assistance data to speed up the positioning speed, resulting in a relatively slow positioning speed.

Further, the terminal may include but not limited to walkie-talkies, law enforcement recorders, and PoC (Push-to-Talk Over Cellular, wireless one-button-to-talk) terminals, etc., specifically taking walkie-talkies as an example, and walkie-talkies may also include various types, such as broadband walkie-talkies , Narrowband walkie-talkies, wide and narrowband walkie-talkies, etc.

In some embodiments, the terminal to be located is a terminal that does not have the ability to connect to the public network, for example, a narrowband walkie-talkie, a law enforcement recorder, and a PoC (Push-to-Talk Over Cellular, wireless push-to-talk) terminal. It does not have the function of connecting to the public network, and cannot connect to the public network to download positioning assistance data. Therefore, it can use the method in this embodiment to obtain positioning assistance data for positioning.

In some embodiments, the terminal to be located is a terminal capable of connecting to the public network, but in some cases, it cannot connect to the public network. The method in the example obtains positioning assistance data for positioning.

It can be understood that, in some cases, after the terminal to be positioned starts positioning, the terminal to be positioned can complete positioning within the first time period. At this time, the terminal does not need to obtain positioning assistance data from other positioned terminals around after completing positioning. . Therefore, in this method, before broadcasting the positioning assistance request, the terminal judges the positioning status, and when the positioning is not completed within the first time period, it then requests other positioned terminals to obtain positioning assistance data, so as to avoid repeatedly obtaining positioning after the terminal has been positioned. Auxiliary data wastes resources.

Specifically, after the terminal to be positioned is turned on and powered on, the positioning has not been completed within the first period of time. After other problems such as inability to receive positioning signals are excluded, it can be determined that the terminal to be positioned cannot download positioning assistance data, so that the positioning speed is relatively fast. Slow, where the first duration can be adjusted by the user based on the actual situation. After determining that the positioning has not been completed within the first duration, the terminal to be positioned will request positioning assistance data from the surrounding positioned terminals by broadcasting a positioning assistance request to speed up its own time. positioning speed. As a specific example, the terminal to be positioned is a narrowband walkie-talkie. The cold start positioning speed of the terminal to be positioned does not use the positioning assistance data, which is related to the strength of the positioning signal, which generally ranges from 1 minute to more than ten minutes. However, when the positioning assistance data is obtained, the cold start time using the positioning assistance data can reach about 10s. Generally, the terminal to be located starts positioning after it is turned on and powered on, and the terminal to be located can start to execute the terminal positioning method described in this application at the same time, so at this time, the first time length is calculated from the time the terminal to be located is powered on.

In some embodiments, the calculation of the first duration may not start immediately after the terminal is powered on, that is, the terminal positioning method described in this application may not be executed immediately after the terminal is powered on.

Step S120: Receive the positioning assistance data broadcast by the positioned terminal within the preset distance range.

Among them, the terminal to be positioned and the positioned terminal can communicate through short-distance wireless transmission, for example, WI-FI (Wireless-Fidelity, wireless fidelity), NFC (Near Field Communication), BLE (Bluetooth Low Energy , Bluetooth Low Energy) etc. The preset distance is determined by the specific communication method between the terminal to be positioned and the positioned terminal, and the preset distance is smaller than the maximum communication distance of the communication method. For example, if the terminal to be positioned and the positioned terminal use WI-FI for communication, The preset distance may be 100m, and if Bluetooth is used for communication between the terminal to be positioned and the positioned terminal, the preset distance may be 10m.

Specifically, the terminal to be positioned receives the positioning assistance data sent by the positioned terminal within the preset distance range centered on it. Positioning assistance data sent by the positioned terminal.

Step S130: Use the positioning module to receive the positioning signal and positioning assistance data to perform positioning.

It can be understood that after any terminal finishes positioning, it can generate positioning assistance data available for transmission, so that it can be used as a positioned terminal, and after it receives a positioning assistance request from a terminal to be positioned within a preset distance range , broadcasting the positioning assistance data by means of short-range wireless transmission, so that the terminal to be positioned can receive the positioning assistance data.

The terminal to be positioned uses the positioning assistance data and the positioning signal to locate itself. After the positioning is completed, the terminal to be positioned can also serve as a positioned terminal to send positioning assistance data to other terminals to be positioned.

In the above solution, if the terminal fails to complete the positioning within the first period of time, it broadcasts a positioning assistance request through short-distance wireless transmission, thereby receiving the positioning assistance data sent by the positioned terminal within the preset distance range, and using the positioning Auxiliary data is used for positioning. Through the above method, the terminal to be positioned can obtain the positioning auxiliary data from the surrounding positioned terminals, which improves the terminal positioning speed, shortens the positioning time, and improves the efficiency.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart of another embodiment of the terminal positioning method of the present application. The terminal positioning method in this embodiment is performed by the terminal to be positioned. The terminal positioning method includes:

Step S210: If the positioning is not completed within the first time period, it is detected whether a positioning signal is received, and if a positioning signal is received, then step S220-step S230 is performed.

For example, if GNSS technology is used for positioning, the positioning signal is a GNSS signal.

It can be understood that, in some cases, after the terminal to be positioned starts positioning, it needs to obtain a positioning signal so as to be able to perform positioning. If the positioning signal cannot be obtained, positioning cannot be performed. For example, in some indoor environments, GNSS signals cannot be obtained, so the terminal cannot use the GNSS technology for positioning. Therefore, in this method, before broadcasting the positioning assistance request, after the terminal judges that the positioning has not been completed within the first time period, it will also determine whether the positioning signal can be obtained. Request to obtain positioning assistance data, so as to avoid resource waste due to failure to obtain positioning signals after obtaining positioning assistance data.

Step S220: Switch the communication mode of the first short-range wireless transmission module to the sending mode.

Wherein, the terminal to be positioned includes a first short-range wireless transmission module for communicating with the positioned terminal. Specifically, the first short-range wireless transmission module may be a Bluetooth module, a WI-FI module, an NFC module, and the like.

It can be understood that the positioned terminal may include a corresponding second short-range wireless transmission module for communicating with the terminal to be positioned, wherein the first short-range wireless transmission module and the second short-range wireless transmission module belong to the same type short-range wireless transmission module. In this embodiment, the first short-range wireless transmission module and the second short-range wireless transmission module are Bluetooth modules as an example for illustration.

Specifically, after the terminal to be positioned determines that the positioning has not been completed within the first time period and the positioning signal is received, the first short-distance wireless transmission module whose communication mode defaults to the receiving mode is switched to the sending mode to send a positioning assistance request.

Step S230: Use the first short-range wireless transmission module to broadcast a positioning assistance request within a second duration.

Wherein, the second duration may be a preset time determined by the user according to actual needs. After the positioning terminal broadcasts the positioning assistance request for a second period of time, it is determined that the sending of the positioning assistance request is completed.

The broadcast positioning assistance request in step S110 can be implemented by steps S220 and S230, and related descriptions can refer to the above-mentioned related content about step S110, which will not be repeated here.

Step S240: Switch the communication mode of the first short-range wireless transmission module from the sending mode to the receiving mode.

After completing the sending of the positioning assistance request, the terminal to be positioned switches the first short-distance wireless transmission module from the sending mode to the receiving mode, and restores the default state, so as to receive the positioning assistance data sent by the positioned terminal.

Step S250: Determine whether there is a positioned terminal broadcasting positioning assistance data within a preset distance range. If yes, execute step S260; otherwise, return to execute the broadcast positioning assistance request.

It can be understood that, in some embodiments, after the terminal to be positioned completes the sending of the positioning assistance request and switches the first short-distance wireless transmission mode to the receiving mode, due to reasons such as that there is no positioned terminal within the preset distance range, , it may not be able to receive the positioning assistance data broadcast by the positioned terminal within a certain period of time. At this time, the terminal to be positioned can broadcast the positioning assistance request again. Judging the current conditions, for example, whether a positioning signal is received, whether the positioning is not completed within the first time period, and so on. Specifically, the terminal to be positioned may return to perform step S210 by broadcasting the positioning assistance request again, wherein, starting from the second broadcast of the positioning assistance request, the terminal to be positioned may perform step S210 with the current time as the starting point, and restart the calculation of the first duration (or other preset time lengths), judge whether the positioning is completed within the period of time, and if the conditions are met, broadcast the positioning assistance request again.

In some embodiments, the terminal to be positioned cannot obtain the positioning assistance data broadcast by the positioned terminal within the preset range after multiple broadcasts of positioning assistance requests. In order to avoid resource waste, after the number of broadcast positioning assistance requests reaches the preset upper limit , the terminal to be positioned may stop broadcasting the positioning assistance request.

In some embodiments, when the terminal to be positioned executes the steps of the terminal positioning method in this embodiment, it can also obtain a positioning signal at the same time, and use the positioning signal to try to perform positioning. If the terminal to be positioned is performing the steps of the terminal positioning method in this embodiment During the process, the positioning signal is used to complete the positioning. If the terminal judges that there is no positioned terminal within the preset distance range to broadcast positioning assistance data, when the positioning assistance request is repeatedly broadcast, the terminal to be positioned determines that the positioning has been completed within the first time period, and no longer broadcasts. The positioning assistance request can avoid the waste of resources caused by broadcasting the positioning assistance request when the terminal has successfully positioned itself using the positioning signal when performing the steps of the terminal positioning method described in this application.

Step S260: Utilize the first short-range wireless transmission module to receive the positioning assistance data broadcasted by the positioned terminals within the preset distance range.

Step S120 can be realized by step S250 and step S260, and related descriptions can refer to the above-mentioned related content about step S120, which will not be repeated here.

Step S270: Utilize the positioning module to receive the positioning signal and positioning assistance data to perform positioning.

After receiving the positioning auxiliary data, the terminal to be positioned can send the above positioning auxiliary data through UART (Universal Asynchronous Receiver/Transmitter, Universal Asynchronous Receiver Transmitter), I2C (Inter-Integrated Circuit, internal integrated circuit, serial communication bus) or USB (Universal Serial Bus Universal Serial Bus) and other methods are transmitted to its positioning module for use.

For the relevant description of step S270, reference may also be made to the relevant content of the above-mentioned step S130, which will not be repeated here.

In the above solution, if the terminal fails to complete the positioning within the first period of time, it broadcasts a positioning assistance request through short-distance wireless transmission, thereby receiving the positioning assistance data sent by the positioned terminal within the preset distance range, and using the positioning Auxiliary data for positioning. Through the above method, the terminal to be positioned can obtain positioning auxiliary data from the surrounding positioned terminals. Without reducing the original positioning performance, the positioning speed of the terminal is improved, the positioning time is shortened, and the positioning time of the terminal is reduced. power consumption, improving efficiency. And in this way, any terminal device with a positioning function can obtain positioning assistance data from other positioned terminals without increasing hardware costs.

Please refer to FIG. 3. FIG. 3 is a schematic flowchart of another embodiment of the terminal positioning method of the present application. The terminal positioning method in this embodiment is performed by the positioned terminal. The terminal positioning method includes:

Step S310: Receive a positioning assistance request sent by a terminal to be positioned within a preset distance range.

It can be understood that the positioned terminal may include a second short-range wireless transmission module for communicating with the terminal to be positioned. Specifically, the second short-range wireless transmission module may be a Bluetooth module, a WI-FI module, an NFC module, etc. . The terminal to be positioned may include a corresponding first short-range wireless transmission module, and the first short-range wireless transmission module and the second short-range wireless transmission module belong to the same type of short-range wireless transmission module. In this embodiment, the first short-range wireless transmission module and the second short-range wireless transmission module are Bluetooth modules as an example for illustration.

Wherein, for the relevant description of the preset distance, reference may be made to the relevant content about the preset distance in the foregoing embodiments, and details are not repeated here.

Specifically, the bluetooth module defaults to the receiving mode, and the positioned terminal uses the second short-range wireless transmission module to receive the positioning assistance request sent by the terminal to be positioned within the preset distance range centered on itself.

Step S320: Generate positioning assistance data in response to the positioning assistance request.

Wherein, the positioned terminal is a terminal that has completed positioning. When the positioned terminal itself performs positioning, it may download or obtain positioning assistance data from other terminals, and use positioning assistance data and positioning signals to complete positioning, or it may only rely on positioning signals. Positioning, whether a positioned terminal can download positioning assistance data and its positioning method will not affect its generation of positioning assistance data.

Specifically, the positioned terminal generates positioning assistance data according to the positioning information, where the positioning information may include positioning related data and/or positioned information.

It can be understood that the specific content contained in the positioning assistance data will change over time, and after the positioning is completed, the positioned terminal will also continuously update the positioning related data, that is, update the positioning assistance data. Therefore, the positioning-related data used for its own positioning may be different from the positioning-related data contained in the positioning assistance data sent to the terminal to be positioned. Further, the positioning data sent by the positioned terminal to different terminals to be positioned at different times The auxiliary data can also be different.

In some embodiments, when the positioned terminal itself performs positioning, it obtains positioning assistance data from the outside, and uses the positioning assistance data and positioning signals to perform positioning. The positioning assistance data acquired and used in positioning does not support direct transmission to other terminals to be positioned, so it is also necessary to generate the latest positioning assistance data available for transmission.

It can be understood that the step of generating the positioning assistance data by the positioned terminal does not necessarily depend on the triggering of the positioning assistance request of the terminal to be positioned. In some embodiments, after the positioning is completed, the positioned terminal will automatically generate positioning assistance data available for transmission. Correspondingly, when the positioning related data is updated, the positioning assistance data will also be updated by itself. The step of locating assistance data does not require triggering of a locating assistance request.

Step S330: broadcast positioning assistance data.

The purpose of step S330 is to allow terminals to be positioned within a preset range to obtain the positioning assistance data, thereby speeding up positioning.

In the above solution, if the terminal to be positioned fails to complete positioning within the first time period, the terminal to be positioned broadcasts a positioning assistance request through short-distance wireless transmission, and the positioned terminal sends a positioning assistance request to the terminal to be positioned within a preset distance range. Data, the terminal to be positioned uses the positioning assistance data to perform positioning. Through the above method, the terminal to be positioned can obtain the positioning assistance data from the surrounding positioned terminals. Without reducing the original positioning performance, the terminal positioning speed is improved and the time is shortened. The positioning time reduces the positioning power consumption of the terminal and improves the efficiency.

Please refer to FIG. 4. FIG. 4 is a schematic flowchart of another embodiment of the terminal positioning method of the present application. The terminal positioning method in this embodiment is performed by the positioned terminal. The terminal positioning method includes:

Step S410: Utilize the second short-range wireless transmission module to receive a positioning assistance request sent by a terminal to be positioned within a preset distance range.

Step S420: Generate positioning assistance data in response to the positioning assistance request.

For related descriptions of step S410 and step S420, reference may be made to the above-mentioned relevant content about step S310 and step S320, and details are not repeated here.

Step S430: Switch the communication mode of the second short-range wireless transmission module from the receiving mode to the sending mode.

It can be understood that the order of step S420 and step S430 can be changed without affecting the broadcast of positioning assistance data by the positioned terminal. Usually, the second short-range wireless transmission module is in the receiving mode by default, and before broadcasting the positioning assistance data, the second short-range wireless transmission module needs to be converted into the sending mode.

Step S440: Use the second short-range wireless transmission module to broadcast positioning assistance data within a third duration.

Wherein, the third duration may be a preset time determined by the user according to actual needs. After the positioned terminal broadcasts the positioning assistance data for a third period of time, it is determined that the sending of the positioning assistance data is completed.

Step S450: Switch the communication mode of the second short-range wireless transmission module from the sending mode to the receiving mode.

After the positioned terminal confirms that the sending of the positioning assistance data is completed, the second short-distance wireless transmission module is switched from the sending mode to the receiving mode, and returns to the default state, so that the information sent by other terminals can be received again.
