[0002] This application relates to the field of mobile communication technology, and in particular to a positioning method, a terminal, a computer-readable storage medium, and a computer program product. [Background Technology]

[0003] The Global Navigation Satellite System (GNSS) is a comprehensive satellite navigation system used to provide global positioning, navigation, and time synchronization services. Typically, terminals that access GNSS can provide accurate and reliable positioning information to a wide range of users.

[0004] However, in scenarios where users use terminals for data transmission such as video shooting, the terminal's data transmission frequency may overlap with the GNSS receiving frequency, leading to a decrease in GNSS sensitivity, making it difficult to locate quickly, or even impossible to locate. [Summary of the Invention]

[0005] This application provides a positioning method that effectively reduces the impact of data transmission scenarios on terminal positioning sensitivity without increasing hardware costs. This application also provides a terminal, a computer-readable storage medium, and a computer program product corresponding to the above method.

[0006] Firstly, this application provides a positioning method. The method includes:

[0007] When it is necessary to locate the terminal, satellite signals are acquired;

[0008] If the terminal is in a data transmission scenario, the data transmission frequency is determined based on the satellite signal; wherein, the data transmission scenario includes a scenario in which the target data in the terminal's storage unit is transferred to an external storage unit;

[0009] The target data is transmitted at the aforementioned data transmission frequency;

[0010] The terminal is located using the satellite signals.

[0011] Secondly, this application provides a positioning device, the device comprising:

[0012] The acquisition unit is used to acquire satellite signals when it is necessary to locate the terminal;

[0013] A determining unit is configured to determine a data transmission frequency based on the satellite signal if the terminal is in a data transmission scenario; wherein the data transmission scenario includes a scenario in which target data in the terminal's storage unit is transferred to an external storage unit;

[0014] A transmission unit is configured to transmit the target data at the data transmission frequency.

[0015] A positioning unit is used to locate the terminal using the satellite signals.

[0016] Thirdly, this application provides a terminal. The terminal includes a positioning device, a processor, and a memory. The positioning device is used to acquire satellite signals and use the satellite signals to locate the terminal. The memory stores instructions, and the processor executes the instructions, causing the terminal to perform the method described in the first aspect of this application or any implementation thereof.

[0017] Fourthly, this application provides a computer-readable storage medium. The computer-readable storage medium stores instructions that, when executed on a terminal, cause the terminal to perform the method described in the first aspect or any implementation thereof.

[0018] Fifthly, this application provides a computer program product. The computer program product includes computer-readable instructions that, when executed on a terminal, cause the terminal to perform the method described in the first aspect or any implementation thereof.

[0019] Based on the implementation methods provided in the above aspects, this application can be further combined to provide more implementation methods.

[0020] Based on the above description, it can be seen that the technical solution of this application has the following beneficial effects:

[0021] Specifically, this method is applied to a terminal. When the terminal needs to be located, the terminal first acquires satellite signals. If the terminal is in a data transmission scenario, the terminal determines the data transmission frequency based on the satellite signals. The data transmission scenario includes the scenario of transmitting target data from the terminal's storage unit to an external storage unit. Then, the terminal transmits the target data at the data transmission frequency and uses the satellite signals to locate the terminal.

[0022] This method takes into account that in data transmission scenarios, the terminal's fixed data transmission frequency may overlap with the GNSS receiving frequency, leading to a decrease in the terminal's positioning sensitivity. Therefore, instead of using a fixed data transmission frequency, the corresponding data transmission frequency is determined by satellite signals. In this way, without increasing additional hardware costs, the impact of data transmission scenarios on the terminal's positioning sensitivity is effectively reduced, achieving rapid positioning.

[0033] To facilitate understanding of the technical solution of this application, the specific technical terms and application scenarios in this application are explained below.

[0034] Global Navigation Satellite System (GNSS): A comprehensive satellite navigation system that provides global positioning, navigation, and time synchronization services. It is widely used for navigation of vehicles, ships, and aircraft, as well as for positioning services of terminals. GNSS satellites broadcast ephemeris signals, which include satellite position and time information. Receivers use the ephemeris signals to calculate a precise geographical location and achieve positioning.

[0035] Terminal: An electronic device with positioning and data transmission capabilities. A terminal can be an electronic device used while in motion, typically possessing wireless communication capabilities and able to connect to the internet or other services via wireless networks. Terminals can also integrate multiple functions such as communication, web browsing, media playback, and photography, and can access various online services, such as email, social media, and cloud storage. Specifically, terminals can include mobile phones, recorders, and walkie-talkies. Walkie-talkies include those based on dedicated networks and those based on public networks. Dedicated networks include Police Digital Trunking (PDT), Digital Mobile Radio (DMR), and Terrestrial Trunked Radio (TETRA), while public networks include 3G, 4G, and Wi-Fi networks.

[0036] In scenarios where users use terminals to transmit data such as video recording, the terminal's data transmission frequency may overlap with the GNSS receiving frequency, leading to a decrease in GNSS sensitivity, making it difficult to locate quickly, or even impossible to locate.

[0037] To address the aforementioned issues, the industry has proposed several solutions. For example, deploying multiple GNSS antennas in the terminal and selecting the GNSS antenna with the best average signal strength for positioning. Another example is adding filtering circuits to the terminal. Yet another example is adding shielding measures such as conductive cloth or copper foil to the terminal.

[0038] However, deploying multiple GNSS antennas requires additional hardware costs, adding filtering circuits is not effective in filtering out co-channel interference, and adding shielding measures makes it difficult to ensure consistency.

[0039] In view of this, this application provides a positioning method. Specifically, the method is applied to a terminal. When positioning of the terminal is required, the terminal first acquires satellite signals. If the terminal is in a data transmission scenario, the terminal determines the data transmission frequency based on the satellite signals. The data transmission scenario includes scenarios where target data is transferred from the terminal's storage unit to an external storage unit. Then, the terminal transmits the target data at the specified data transmission frequency and uses the satellite signals to position the terminal.

[0040] This method takes into account that in data transmission scenarios, the terminal's fixed data transmission frequency may overlap with the GNSS receiving frequency, leading to a decrease in the terminal's positioning sensitivity. Therefore, instead of using a fixed data transmission frequency, the corresponding data transmission frequency is determined by satellite signals. In this way, without increasing additional hardware costs, the impact of data transmission scenarios on the terminal's positioning sensitivity is effectively reduced, achieving rapid positioning.

[0041] Next, the positioning method provided in this application will be described in detail with reference to the accompanying drawings.

[0042] Referring to Figure 1, a flowchart of a positioning method is shown. This method can be executed by a terminal and specifically includes the following steps:

[0043] S101: Acquire satellite signals when it is necessary to locate the terminal.

[0044] In this embodiment of the application, the terminal has GNSS positioning function, and the need to locate the terminal can be understood as the terminal having a positioning requirement.

[0045] In practice, the terminal can acquire satellite signals through a deployed GNSS antenna. These satellite signals include satellite ephemeris signals, which are signals emitted by satellites. Specifically, the satellite signals can include satellite position and time data. The terminal can use these satellite signals to determine the distance between itself and the satellite, thereby achieving terminal positioning.

[0046] In practice, when the terminal needs to be located, such as when the user enables the terminal's location function or when the user needs to locate the terminal while using it, the terminal can acquire satellite signals at a fixed receiving frequency.

[0047] S102: If the terminal is in a data transmission scenario, determine the data transmission frequency based on the satellite signal.

[0048] In the embodiments of this application, the data transmission scenario includes transferring target data from the terminal's storage unit to an external storage unit. In some possible implementations, the terminal's storage unit can be random-access memory (RAM), and the external storage unit can be a memory card, such as an SD card.

[0049] In data transmission scenarios, a terminal can transfer locally stored target data to an external storage unit for storage. In some embodiments, the terminal needs to perform positioning in data transmission scenarios. In related technologies, terminals typically transmit data at a fixed data transmission frequency. However, this fixed data transmission frequency can overlap with the receiving frequency for acquiring satellite signals, causing a decrease in GNSS positioning sensitivity. Consequently, in data transmission scenarios, the terminal may require a longer time to achieve successful positioning, or may even fail to locate at all.

[0050] In some possible implementations, the data transmission scenario is a video recording scenario using the terminal. Of course, the data transmission scenario can also be a file copying scenario using the terminal. The transmitted data can include video, text, audio, etc. This embodiment only uses a video recording scenario as an example for illustration. During video recording, the generated target data (e.g., video data) can be transferred from the terminal's RAM to the memory card for storage, avoiding excessive RAM usage. Furthermore, since the video recorded by the terminal can carry location information, the terminal needs to perform positioning in the video recording scenario.

[0051] In this embodiment, the terminal can determine the data transmission frequency based on satellite signals. In other words, unlike the method of transmitting data using a fixed data transmission frequency, determining the corresponding data transmission frequency through satellite signals can, to some extent, reduce the problem of decreased GNSS positioning sensitivity caused by data transmission.

[0052] In practice, the terminal can obtain the signal quality of each satellite and determine the number of satellites whose signal quality meets the set conditions. Then, based on the number of satellites, the data transmission frequency is determined.

[0053] In this context, "meeting the set conditions" can mean that the signal quality is relatively good, or that the signal quality is within a preset threshold range. In other words, the data transmission frequency is determined by the number of satellites with good signal quality during the current data transmission process, allowing for targeted data transmission frequency selection based on specific circumstances.

[0054] In some possible implementations, the signal quality of a satellite can be characterized by the carrier-to-noise ratio (CNR), or by other parameters commonly used to represent signal quality, such as signal strength and carrier noise density. This embodiment does not limit this, and only the CNR is used as an example for illustration. Thus, by obtaining the CNR of each satellite, the number of satellites with a CNR greater than a first threshold is determined.

[0055] Referring to Figure 2, the terminal acquires satellite signals. When the terminal is in a data transmission scenario, it can determine the carrier-to-noise ratio of each satellite based on the satellite signals. Then, it determines the number of satellites with a carrier-to-noise ratio greater than a first threshold, and then determines the data transmission frequency based on the number of satellites.

[0056] The carrier-to-noise ratio (C / N) of a satellite refers to the ratio of carrier power to noise power. After the terminal acquires the satellite signal, the C / N of each satellite can be calculated. The higher the C / N of a satellite, the more accurate and reliable the positioning of the mobile device.

[0057] The first threshold can be used to measure the strength of a satellite signal. That is, if the satellite's carrier-to-noise ratio (CNR) is greater than the first threshold, it indicates that the satellite signal is strong and of good quality. Similarly, if the satellite's CNR is less than or equal to the first threshold, it indicates that the satellite signal is weak and of poor quality.

[0058] The first threshold can be set according to actual needs. For example, the first threshold can be 24dB*Hz. Or, for example, the first threshold can be 28dB*Hz.

[0059] In this embodiment, the data transmission frequency is determined by the number of satellites with a carrier-to-noise ratio greater than a first threshold. Specifically, if the number of satellites is less than or equal to a second threshold, the terminal can maintain the data transmission frequency at the first frequency; if the number of satellites is greater than the second frequency, the terminal can adjust the data transmission frequency to the second frequency.

[0060] The second threshold is used to measure whether the terminal can perform positioning. That is, if the number of satellites is less than or equal to the second threshold, it indicates that there are few satellites with strong signals, and the terminal cannot perform positioning using the acquired satellite signals. Similarly, if the number of satellites is greater than the second threshold, it indicates that there are many satellites with strong signals, and the terminal can perform positioning using the acquired satellite signals.

[0061] In some embodiments, the second threshold can be 3. It is understood that terminal positioning can be interpreted as determining the location of a point in three-dimensional space. Since GNSS positioning involves three spatial dimensions (longitude, latitude, and altitude) and one time dimension (used to correct the time difference between the satellite clock and the receiver clock), when the number of satellites with strong signals is greater than 3 (e.g., 4), the terminal can be positioned using satellite signals; when the number of satellites with strong signals is less than or equal to 3, the terminal cannot be positioned using satellite signals.

[0062] In the embodiments of this application, the first frequency is greater than the second frequency. In some possible implementations, the second frequency can be 0.5 to 1 times the satellite navigation message frequency.

[0063] In other words, the terminal's default data transmission frequency can be the first frequency. When the number of satellites exceeds a second threshold, the data transmission frequency is adjusted to the second frequency. When there are few satellites with strong signals and the terminal cannot locate itself using the acquired satellite signals, the data transmission frequency is higher and the time interval between two adjacent data transmissions is shorter. When there are many satellites with strong signals and the terminal can locate itself using the acquired satellite signals, the data transmission frequency is lower and the time interval between two adjacent data transmissions is longer.

[0064] Understandably, when there are few satellites with strong signals, the terminal cannot locate itself using the acquired satellite signals. Therefore, the impact of data transmission on GNSS positioning sensitivity is not a concern. In this case, shorter data transmission intervals can be used to improve data transmission efficiency. When there are many satellites with strong signals, longer data transmission intervals are used to avoid the impact of frequent data transmission on GNSS positioning sensitivity, thus enabling the terminal to locate itself quickly.

[0065] S103: Transmit target data at the data transmission frequency.

[0066] Once the terminal determines the data transmission frequency, the target data in the terminal's storage unit can be transferred to the external storage unit at that frequency.

[0067] S104: Use satellite signals to locate the terminal.

[0068] Correspondingly, the terminal can use the acquired satellite signals to achieve rapid positioning. Although steps S103 and S104 are different steps, in this embodiment, data transmission and positioning do not have a sequential order. That is, the terminal performs positioning while transmitting target data.

[0069] Furthermore, when the data transmission frequency is the second frequency, if the terminal successfully locates the target data, the terminal can adjust the data transmission frequency to the first frequency and transmit the target data at the first frequency.

[0070] In other words, once the terminal successfully locates itself after transmitting data at longer intervals, it can switch to shorter intervals to continue transmitting data. This not only improves the terminal's GNSS anti-interference capability to some extent but also ensures the stability of the terminal's operation.

[0071] The following explanation will be based on actual measurement data. As shown in Figures 3A and 3B, the first row of waveforms is the waveform of the clock signal, the second row of waveforms is the waveform of the power supply signal. In this embodiment, since power is required during data transmission, the waveform of the power supply signal can be used to characterize the time interval of data transmission. The third row of waveforms is the waveform of the command signal, and the fourth row of waveforms is the waveform of the data signal.

[0072] Figure 3A is a schematic diagram of signal changes when the terminal transmits data at the first frequency. It can be seen that the terminal transmits data at intervals of approximately 5 seconds. Figure 3B is a schematic diagram of signal changes when the terminal transmits data at the second frequency. It can be seen that the terminal transmits data at intervals of approximately 20 seconds.

[0073] The effects of the positioning method provided in the embodiments of this application will be described below, as shown in Tables 1 and 2. Table 1 shows the results of tests conducted in the laboratory, and Table 2 shows the results of tests conducted outdoors.

[0074] Table 1

[0075] Table 2

[0076] As can be seen from the test results in Tables 1 and 2, after the terminal applies the positioning method provided in the embodiments of this application, it can effectively improve the positioning speed in video shooting scenarios and reduce GNSS interference.

[0077] As can be seen from the above description, the positioning method provided in this application is applied to a terminal. The terminal first acquires satellite signals. In response to the terminal being in a data transmission scenario and the terminal failing to locate itself, the terminal determines the data transmission frequency based on the satellite signals. The data transmission scenario includes the scenario of transmitting target data from the terminal's storage unit to an external storage unit. Then, the terminal transmits the target data at the specified data transmission frequency.

[0078] This method takes into account that in data transmission scenarios, the terminal's fixed data transmission frequency may overlap with the GNSS receiving frequency, leading to a decrease in the terminal's positioning sensitivity. Therefore, when the terminal fails to locate, the corresponding data transmission frequency is determined through satellite signals, rather than using a fixed data transmission frequency. In this way, the impact of data transmission scenarios on the terminal's positioning sensitivity is effectively reduced without increasing additional hardware costs.

[0096] In some possible implementations, the data transmission frequency is the second frequency, and the transmission module 403 is further configured to:

[0097] After the terminal is successfully located, the data transmission frequency is adjusted to the first frequency, and the target data is transmitted at the first frequency.
