[0060] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0061] The technical solutions provided by various embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0062] In the related technology, terminal devices such as mobile phones generally support satellite positioning functions. Positioning satellites broadcast navigation message information in a certain sequence, and the positioning module inside the mobile phone receives the navigation message broadcast by the satellite and decodes and calculates it in an agreed manner to obtain the latitude and longitude data of the current location of the mobile phone. The frequency bands of the navigation message broadcast by the positioning satellite are currently mainly divided into L1 band and L5 band; L1 band is a low-power navigation band, which is sufficient for satellite positioning and navigation scenarios under general circumstances. The navigation signal under this band is susceptible to interference, so the positioning point drift will occur in areas with high-rise buildings in the city, that is, inaccurate positioning; L5 band is a high-power navigation band, which has better anti-interference, which makes it still have better positioning accuracy even in extreme situations such as high-rise buildings and overpasses. The positioning module equipped with only L1 band in the mobile phone is called single-mode, and the positioning module equipped with both L1 band and L5 band is called dual-mode.

[0063] Although some mobile phones are equipped with both L1 and L5 band positioning modules, in fact, there is no need to use the L5 band in some cases. Take the suburbs as an example. In the open field environment, the L1 band can actually achieve very good positioning accuracy. Even if the L5 band is used, the positioning accuracy may only increase by about 0.1 meters, but the power consumption is several times higher than that of using only the L1 band, resulting in high power consumption and poor battery life of the mobile phone.

[0064] Currently, if Figure 1 As shown in the figure, there are operations that limit the L5 frequency band on smartphones, such as the super power saving mode, in which the positioning function of the mobile phone is limited (the L1 frequency band and the L5 frequency band are both invalid); and the smart power saving mode, which directly disables the L5 frequency band when the mobile phone can send and receive the L5 frequency band. When the user manually turns on this mode, the L5 frequency band function will be actively disabled in order to save power. However, when the user needs to use the L5 frequency band, the smart power saving mode must be turned off, resulting in a poor user experience.

[0065] Based on this, an embodiment of the present disclosure provides a positioning method, which is applied to a terminal device. Figure 2 A schematic diagram of a positioning method according to an exemplary embodiment Figure 1 ,like Figure 2 As shown, the positioning method provided by the embodiment of the present disclosure includes at least the following steps:

[0066] Step 110: When the frequency band selection switch of the terminal device is turned on, the current location information is sent to a cloud server that has established a communication connection with the terminal device;

[0067] Step 120: receiving a target result fed back by the cloud server based on the current location information; the target result is used to characterize the density of the area corresponding to the current location information;

[0068] Step 130: When the target result meets the preset conditions, rewrite the configuration file of the target frequency band so that the terminal device can deactivate the target frequency band; the target frequency band is the frequency band with the lowest center frequency of at least two frequency bands simultaneously supported by the terminal device.

[0069] In the embodiments of the present disclosure, the above-mentioned terminal devices may include: mobile phones, tablet computers, smart watches, digital cameras, head mounted display devices (Head Mounted Display, HMD), etc., which are not limited in the embodiments of the present disclosure.

[0070] In step 110, the frequency band selection switch may be a button of the intelligent satellite frequency band selection function set in the terminal device. After turning on the frequency band selection switch, the system of the terminal device may automatically select to transmit or disable a frequency band supported by the terminal device to save the positioning power consumption of the terminal device; after turning off the frequency band selection switch, all frequency bands supported by the terminal device are transmitted and received by default.

[0071] Exemplarily, the terminal device may be a dual-mode mobile phone supporting L1 and L5 bands. After turning on the above-mentioned band selection switch, the mobile phone system can intelligently transmit and receive or disable the L5 band to save mobile phone positioning power consumption. If it is turned off, it is assumed that the mobile phone can transmit and receive the L5 band.

[0072] The above cloud server is a simple, efficient, safe, reliable, and elastic computing service with scalable processing power. Its management method is simpler and more efficient than that of a physical server, and it can support large amounts of data computing. The above cloud server establishes a communication connection with the above terminal device to send the big data computing that cannot be supported by the terminal device to the cloud server for computing, so as to save resources and improve efficiency.

[0073] The above-mentioned current location information may be the longitude and latitude data corresponding to the location of the above-mentioned terminal device at the current moment.

[0074] It is understandable that the terminal device has a positioning function, and the positioning service, as a basic service of the terminal device system, runs automatically with the startup of the terminal device. The positioning module inside the terminal device receives the navigation message broadcast by the satellite and decodes and calculates it in an agreed manner, thereby obtaining the latitude and longitude data corresponding to the current location of the terminal device.

[0075] Among them, the logic of using this positioning function by third-party applications (for example, navigation applications, trading applications, etc.) is to obtain the agent of the positioning service (Location Manager Service, LMS) through the Location Manager (LM) in the terminal device, and then call the system interface (System Application Programming Interface, System-API) provided by the service to initiate positioning, and obtain the current location information of the terminal device through the callback function, initiate the positioning process, and the bottom layer feeds back the current location information to the upper layer through callback.

[0076] Here, the callback function is the necessary path for the bottom layer location information in the terminal device to be reported to the upper layer to the application; for example, the callback function may be handleReportLocation() or reportLocation().

[0077] In the disclosed embodiment, after the callback function in the terminal device obtains the current location information reported by the bottom layer of the terminal device, the current location information can be synchronized to the above-mentioned cloud server in real time, so as to analyze the current location information of the terminal device through the cloud server.

[0078] In one embodiment of the present disclosure, Figure 3 As shown, the positioning method may further include: when the positioning module of the terminal device is in working state and receives a request for automatic switching of frequency bands, turning on the frequency band selection switch. In this way, when the terminal device is capable of positioning navigation and needs to be able to automatically switch frequency bands, the frequency band selection switch of the terminal device can be turned on, thereby saving the positioning power consumption of the terminal device and improving the endurance of the terminal device.

[0079] Here, the above-mentioned positioning module may include but is not limited to a global positioning system (GPS) module, a GLONASS (GLONASS) satellite navigation system (GALILEO) module, and a Beidou Navigation Satellite System (BDS) module.

[0080] In step 120, the target result may be a result calculated and analyzed by the cloud server based on the current location information.

[0081] Among them, the above-mentioned target result can be used to characterize the regional density of the location of the above-mentioned terminal device at the current moment; that is, the target result can be used to characterize the building conditions in the surrounding area of ​​the location of the above-mentioned terminal device at the current moment.

[0082] For example, in the surrounding area (for example, the area is 100 square meters) of the current location of the terminal device, there are 8 buildings with a height of more than 30 meters and 3 buildings with a height of less than 30 meters. At this time, the density of the area can be expressed as the ratio between the number of buildings with a height of more than 30 meters and the area of ​​the surrounding area. The above target result can be 8 / 100=0.08.

[0083] It can be understood that the above-mentioned target result can be calculated in the above-mentioned cloud server, and then fed back to the above-mentioned terminal device by the above-mentioned cloud server, so that the terminal device can switch different frequency bands supported by the terminal device at the same time based on the target result to switch different positioning modes.

[0084] In step 130, when the target result is a target density value, the target result satisfies the preset condition that the target density value is less than the preset density threshold; when the target result is a target score, the target result satisfies the preset condition that the target score is greater than the preset score; and so on.

[0085] The above-mentioned target frequency band may include but is not limited to the L5 frequency band; wherein, the L5 frequency band refers to the band of the carrier of the navigation satellite signal, and the carrier center frequency corresponding to the L5 frequency band is 1176.45 MHz. The L5 frequency band is the third type of civil GPS signal, which is beneficial to the "cycle slip detection", ionospheric delay error correction and integer ambiguity determination in the GPS measurement process, and improves the civil positioning accuracy from 5 meters to 30 centimeters.

[0086] Here, the frequency bands supported by the terminal device at the same time may include at least L1 and L5. Among them, L1 also refers to the carrier wave band of the navigation satellite signal. The carrier center frequency corresponding to L1 is 1575.42 MHz. The radio waves in this frequency propagate in a straight line in the ionosphere and are less affected by noise, which meets the requirements of navigation satellite signals.

[0087] In the embodiment of the present disclosure, the configuration file may be a file corresponding to the target frequency band that can be configured by the positioning module of the terminal device; for example, the configuration file may be MNL-Config.xml.

[0088] It can be understood that when the received target result meets the preset conditions, the above configuration file can be rewritten to send a corresponding command to the positioning module of the terminal device so that the terminal device can deactivate the above target frequency band.

[0089] In one embodiment of the present disclosure, Figure 3 As shown, the positioning method may also include:

[0090] In response to the highest authority request, turning on the mandatory use switch so that the terminal device can transmit and receive the target frequency band; or,

[0091] In response to the highest authority request, the forced use switch is turned off so that the terminal device can deactivate the target frequency band.

[0092] In this way, the highest authority forced use switch function can be customized by the user, making up for the defect in the related technology that the target frequency band is disabled due to turning on the power saving mode, so that the terminal device can send, receive or disable the target frequency band more flexibly, thereby improving the user experience.

[0093] Here, the above-mentioned forced use switch can be a button with the highest setting authority and an independent custom frequency band set in the above-mentioned terminal device. After turning on the forced use switch, even if the terminal device is in power saving mode or a mode that can automatically switch frequency bands, the user can force the target frequency band to be sent or received or disabled; that is, when the above-mentioned forced use switch is in the turned-on state, the terminal device can send or receive the target frequency band; when the above-mentioned forced use switch is in the turned-off state, the terminal device can disable the target frequency band.

[0094] A positioning method provided by an embodiment of the present disclosure is applied to a terminal device and may include: when the frequency band selection switch of the terminal device is in the on state, sending current location information to a cloud server with which a communication connection is established with the terminal device; receiving a target result fed back by the cloud server based on the current location information; the target result is used to characterize the regional density corresponding to the current location information; when the target result meets a preset condition, rewriting the configuration file of the target frequency band so that the terminal device can deactivate the target frequency band; the target frequency band is a frequency band with the lowest center frequency of at least two frequency bands simultaneously supported by the terminal device. That is to say, when the frequency band selection switch of the terminal device is in the on state, the target result corresponding to the current location information of the terminal device can be fed back through the cloud server with which a communication connection is established with the terminal device, so as to control the terminal device to automatically switch different frequency bands simultaneously supported by the terminal device when it is in different positions. In this way, when the target result fed back to the terminal device by the cloud server meets the preset condition, the terminal device can deactivate the target frequency band matching the current location information, thereby saving the power consumption of the terminal device, improving the endurance of the terminal device, and improving the user experience.

[0095] In one embodiment of the present disclosure, the target result includes a target density value or a target score; in step 130, when the target result satisfies a preset condition, the configuration file of the target frequency band is rewritten so that the terminal device can deactivate the target frequency band. The specific process may include:

[0096] When the target density value is less than a preset density threshold, or the target score is greater than a preset score, the configuration file of the target frequency band is rewritten so that the terminal device can deactivate the target frequency band.

[0097] In this way, by comparing the target density value with the preset density threshold or the target score with the preset score, it can be determined whether to rewrite the configuration file of the target frequency band when the preset conditions are met, so that the terminal device can deactivate the target frequency band, thereby enabling the terminal device to automatically switch between different frequency bands supported simultaneously when the terminal device is in different positions, thereby saving power consumption of the terminal device, improving the battery life of the terminal device, and enhancing the user experience.

[0098] Among them, the above-mentioned target density value can be the density value of the relevant area corresponding to the above-mentioned current location information calculated by the above-mentioned cloud server; the above-mentioned preset density threshold can be the regional density threshold obtained in advance by the above-mentioned terminal device based on a large number of sample experiments.

[0099] It can be understood that the above-mentioned target density value is less than the above-mentioned preset density threshold, or the above-mentioned target score is greater than the above-mentioned preset score, which can both indicate that the location area where the above-mentioned terminal device is located at the current moment is in an open state (for example, suburbs); at this time, the terminal device can achieve good positioning accuracy by transmitting and receiving the L1 frequency band, and there is no need to transmit and receive the target frequency band, namely the L5 frequency band, to increase the power consumption of the terminal device. Therefore, it is necessary for the terminal device to be able to deactivate the target frequency band to save the power consumption of the terminal device and improve the battery life of the terminal device.

[0100] In the disclosed embodiment, the target score may be a score assigned by the cloud server based on the area density corresponding to the current location information; the preset score may be a score threshold value corresponding to the area density obtained in advance by the terminal device based on a large number of sample experiments.

[0101] It can be understood that if the above-mentioned target score is greater than the above-mentioned preset score, it can be indicated that the location area where the above-mentioned terminal device is located at the current moment is in an open state (for example, the suburbs); at this time, the terminal device can achieve good positioning accuracy by transmitting and receiving the L1 frequency band, and there is no need to transmit and receive the target frequency band, namely the L5 frequency band to increase the power consumption of the terminal device. Therefore, it is necessary for the terminal device to be able to deactivate the target frequency band to save the power consumption of the terminal device and improve the battery life of the terminal device.

[0102] It should be noted that the above target density value is positively correlated with the regional density, while the above target score is negatively correlated with the regional density.

[0103] In some embodiments, the positioning method may further include:

[0104] When the target density value is greater than or equal to the preset density threshold, or the target score is less than or equal to the preset score, the configuration file of the target frequency band is updated so that the terminal device can transmit and receive the target frequency band.

[0105] In this way, by comparing the target density value with the preset density threshold or the target score with the preset score, it can be determined whether to update the configuration file of the target frequency band when the preset conditions are not met, so that the terminal device can send and receive the target frequency band, thereby saving the power consumption of the terminal device, improving the battery life of the terminal device, and improving the user experience.

[0106] It can be understood that the above-mentioned target density value greater than or equal to the above-mentioned preset density threshold can be indicated that the location area where the above-mentioned terminal device is located at the current moment is in a densely surrounded state (for example, an urban area); at this time, the positioning module of the terminal device is easily affected by the surrounding buildings, and the positioning navigation signal is interfered, so it is necessary for the terminal device to be able to send and receive the target frequency band to improve the positioning accuracy of the terminal device.

[0107] For example, the preset score of the above-mentioned terminal device is 60 points. When the target score calculated by the above-mentioned cloud server based on the current location information of the terminal device is 70 points, it means that the terminal device can deactivate the L5 frequency band; when the target score calculated by the above-mentioned cloud server based on the current location information of the terminal device is 50 points, it means that the terminal device can transmit and receive the L5 frequency band.

[0108] Figure 4 A schematic diagram of a positioning method according to an exemplary embodiment Figure 2 ,like Figure 4 As shown, the positioning method provided in the embodiment of the present disclosure, applied to a cloud server, may at least include the following steps:

[0109] Step 210: receiving current location information sent by a terminal device that has established a communication connection with the cloud server;

[0110] Step 220: Based on the current location information, determine a target result corresponding to the current location information; the target result is used to characterize the density of the area corresponding to the current location information;

[0111] Step 230: Send the target result to the terminal device, so that the terminal device can deactivate the target frequency band based on the target result.

[0112] In step 210, the current location information may be based on the longitude and latitude data corresponding to the current location of the terminal device obtained by the positioning module of the terminal device by receiving the navigation message broadcast by the satellite and decoding and calculating it in an agreed manner.

[0113] In the embodiment of the present disclosure, the current location information may be synchronized to the cloud server in real time through a callback function in the terminal device.

[0114] In step 220, the target result may be calculated in the cloud server based on the current location information.

[0115] In an embodiment of the present disclosure, determining a target result corresponding to the current position information based on the current position information may include: determining a target area corresponding to the current position information based on a pre-trained area segmentation model and the current position information; determining a target density value corresponding to the target area based on the target area; or, determining a target density value corresponding to the target area based on the target area, and determining a target score based on the target density value.

[0116] In step 230, the target frequency band may be a frequency band with the lowest center frequency among at least two frequency bands simultaneously supported by the terminal device; for example, the target frequency band may be an L5 frequency band.

[0117] It is understandable that the cloud server can transmit the target result back to the terminal device so that the terminal device can determine whether the terminal device transmits or disables the target frequency band based on the target result. That is, if the target result meets the preset conditions, the configuration file of the target frequency band can be rewritten so that the terminal device can disable the target frequency band; if the target result does not meet the preset conditions, the configuration file of the target frequency band can be updated so that the terminal device can transmit or receive the target frequency band.

[0118] A positioning method provided by an embodiment of the present disclosure is applied to a cloud server and may include: receiving current location information sent by a terminal device that has established a communication connection with the cloud server; determining a target result corresponding to the current location information based on the current location information; the target result is used to characterize the regional density corresponding to the current location information; and sending the target result to the terminal device so that the terminal device can deactivate the target frequency band based on the target result. In other words, the target result corresponding to the current location information can be determined by receiving the current location information sent by the terminal device, and the target result can be sent to the terminal device to control the terminal device to automatically switch different frequency bands supported by the terminal device at the same time when the terminal device is in different positions. In this way, the cloud server of the embodiment of the present disclosure feeds back the target result determined based on the current location information to the terminal device, so that the terminal device can deactivate the target frequency band matching the current location information, thereby saving the power consumption of the terminal device, improving the endurance of the terminal device, and improving the user experience.

[0119] In one embodiment of the present disclosure, the specific process of determining the target result corresponding to the current location information based on the current location information in step 220 may include:

[0120] Determine a target area corresponding to the current position information based on a pre-trained region segmentation model and the current position information;

[0121] Based on the target area, the target result corresponding to the target area is determined.

[0122] In this way, the target area corresponding to the current location information can be determined through the pre-trained area segmentation model and the current location information, and then the corresponding target result can be calculated based on the target area, thereby improving the accuracy of the target result, so that subsequent terminal devices can send, receive or deactivate the target frequency band based on the target result, thereby improving the user experience.

[0123] The region segmentation model may include a map model pre-stored in the cloud server, or a 3D map model in a third-party application (eg, a navigation application). The target region may be a region determined with the current location information as the center.

[0124] It can be understood that when the above-mentioned target result is a target density value, the target density value can be obtained based on the ratio of the number of buildings exceeding a preset height in the above-mentioned target area to the area of ​​the target area; when the above-mentioned target result is a target score, the above-mentioned cloud server can score based on the target density value to obtain the target score.

[0125] In some embodiments, determining the target area corresponding to the current location information based on the pre-trained region segmentation model and the current location information may include:

[0126] Determine the trajectory information of the terminal device within a time period from a current time point corresponding to the current location information to a preset time point;

[0127] Based on the trajectory information, determining center position information corresponding to the trajectory information;

[0128] The center position information and the preset radius are input into the region segmentation model to obtain the target region.

[0129] In this way, the center position information corresponding to the trajectory information can be determined by the trajectory information of the terminal device in the time period from the current time point to the preset time point, so as to determine the target area in the area segmentation model, so that the subsequent target results can be calculated more accurately.

[0130] Among them, the above-mentioned preset time point can be a pre-set time point; the above-mentioned trajectory information can be the trajectory information formed by the change of the position of the above-mentioned terminal device in the time period from the current time point to the preset time point.

[0131] In the disclosed embodiment, the central location information may be the location information corresponding to the center point of the minimum area range determined by the cloud server based on each positioning point in the trajectory information. The preset radius may be a radius threshold value that can reflect the density of the area obtained by the cloud server in advance based on a large number of sample experiments.

[0132] Here, if the position of the terminal device does not change during the period from the current time point to the preset time point, the trajectory information of the terminal device is the current position information, and the current position information can be directly used as the central position information.

[0133] It should be noted that the target area may be a circular area determined based on the center position information and a preset radius, or a square area determined based on the center position information and a preset side length, and the embodiment of the present disclosure does not limit this.

[0134] In one embodiment of the present disclosure, determining the center position information corresponding to the trajectory information based on the trajectory information may include:

[0135] Based on the trajectory information and a preset area, determining a region range corresponding to the trajectory information;

[0136] Based on the area range, the center position information of the area range is determined.

[0137] In this way, the area range corresponding to the trajectory information can be determined by the trajectory information and the preset area, so as to determine the central position information of the area range, thereby being able to more accurately determine the target area corresponding to the terminal device.

[0138] Among them, the above-mentioned preset area can be the minimum area determined by the above-mentioned cloud server according to the trajectory information of the above-mentioned terminal device; the above-mentioned area range can be the minimum area range that can surround all positioning points in the above-mentioned trajectory information.

[0139] Here, the positioning point of the terminal device whose position changes during the period from the current time point to the preset time point is enclosed in the above-mentioned area by a preset area to calculate the central position information within the area; at this time, the central position information may be the above-mentioned current position information, or it may be the position information corresponding to other time points.

[0140] For example, Figure 5 As shown, the above-mentioned cloud server determines the above-mentioned target result based on the current location information of the terminal device by using a scanning method based on a preset radius. According to the trajectory information corresponding to the current location information, the 3D map model of the third-party application is loaded, and the preset radius R is used as a reference. The high-rise building model in the circular target area currently located within the preset radius R is scanned clockwise in one circle, and mapped into two-dimensional points on the plane. By calculating the distribution of the final two-dimensional points, it is divided into different regional densities such as densely surrounded or open, so as to calculate the target result of the target area. When the density of the area is densely surrounded, the cloud server can send the target result to the terminal device, and determine in the terminal device that the preset conditions are not met to transmit and receive the L5 frequency band; when the density of the area is open, the cloud server can also send the target result to the terminal device, and determine in the terminal device that the preset conditions are met to deactivate the L5 frequency band, that is, only transmit and receive the L1 frequency band.

[0145] Step 604: The cloud server determines the center location information of the area range based on the area range;

[0146] Step 605: The cloud server inputs the center location information and the preset radius into a pre-trained region segmentation model to obtain a target region corresponding to the current location information;

[0147] Step 606: The cloud server determines a target result corresponding to the target area based on the target area;

[0148] Step 607: The cloud server sends the target result to the terminal device; the target result includes a target density value or a target score;

[0149] Step 608: When the target density value is less than a preset density threshold, or the target score is greater than a preset score, the terminal device rewrites the configuration file of the target frequency band so that the terminal device can deactivate the target frequency band;

[0150] Step 609: When the target density value is greater than or equal to the preset density threshold, or the target score is less than or equal to the preset score, the terminal device updates the configuration file of the target frequency band so that the terminal device can send and receive the target frequency band.
