[0046] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0048] When positioning, the existing technology performs real-time positioning and solving in the terminal device. The terminal device obtains satellite observation data from the positioning module, and then transmits the observation data to the high-precision positioning platform device through the Subscriber Identity Module Card (SIM) card through the gateway device, and obtains the differential data of the corresponding reference observation station. The positioning module then performs differential solution to obtain a high-precision position, and other applications then obtain high-precision position data. However, the interaction efficiency between the SIM card of the terminal device and the positioning platform device is low. The Global Positioning System Fix Data (GGA) data must be sent once to receive differential data. The GGA data sending frequency is limited by when the last differential data can be returned. The frequency of differential data reception is too low, resulting in a large differential data age.

[0049] In order to solve the existing technology, the embodiments of the present application provide a positioning method, device, equipment, computer storage medium, and program product. The method first obtains positioning data through a terminal device, and sends positioning data to a positioning platform device through a gateway device according to an independent bearer protocol BIP link established between a user identity module SIM card application and a gateway device; the SIM card application and the corresponding independent bearer protocol (Bearer Independent Protocol, BIP) link are used to ensure compatibility and interoperability between different devices and networks. The positioning platform device sends corresponding differential data to the gateway device according to the received positioning data according to the gateway device according to the preset sending frequency; the differential data is actively pushed, and there is no need to wait for each positioning data to be sent before pushing the differential data, which can increase the acquisition frequency of the differential data. The gateway device sends the differential data to the SIM card application of the terminal device. The terminal device receives the differential data sent by the gateway device through the BIP link and corrects the positioning data to obtain the target positioning data. The embodiment of the present application establishes a BIP link and an Internet protocol connection link, actively pushes differential data according to the preset sending frequency, improves the acquisition frequency of differential data, and improves the positioning efficiency.

[0050] Figure 1 FIG. 1 is a flow chart of a positioning method provided by an embodiment of the present invention. Figure 1 As shown, the method may include the following steps: S101 to S106.

[0051] S101, the terminal device obtains the positioning data of the terminal device.

[0052] In some embodiments, the positioning data is the positioning information of the terminal device acquired in real time, and may include information such as the latitude and longitude coordinates of the positioning point, speed, and positioning time.

[0053] In some embodiments, the terminal device has a built-in positioning module, and the positioning data obtains National Marine Electronics Association (NMEA) positioning data through the positioning module of the terminal device, and obtains GGA data from the NMEA data as the positioning data obtained by the terminal device.

[0054] S102: When the SIM card application of the terminal device establishes an independent bearer protocol BIP link with the gateway device, the terminal device sends positioning data to the gateway device.

[0055] In some embodiments, the terminal device encapsulates the positioning data into a BIP data packet and sends it to the gateway device via a BIP link.

[0056] Among them, the BIP protocol is a protocol independent of wireless access technology. Through the BIP link, the transmission of positioning data can be guaranteed not to be affected by other communication data, thereby improving the stability and reliability of data transmission. It can also adapt to different network environments and access technologies, enabling terminal devices to transmit positioning data under different network conditions.

[0057] S103: The gateway device receives the positioning data, and sends the positioning data to the positioning platform device when a differential data communication link is established between the gateway device and the positioning platform device.

[0058] In some embodiments, the gateway device receives the BIP data packet sent by the terminal device and parses the positioning data encapsulated in the BIP data packet; after the parsing is completed, the positioning data is encapsulated into a differential data communication protocol data packet through the differential data communication protocol, and the differential data communication protocol data packet is sent to the positioning platform device.

[0059] In some embodiments, the differential data communication protocol may be Networked Transport of RTCM via Internet Protocol (NTRIP).

[0060] S104, the positioning platform device receives the positioning data, and sends differential data corresponding to the positioning data to the gateway device through a differential data communication link according to a preset sending frequency.

[0061] Among them, the differential data communication link is a long connection. After the positioning platform device sends differential data to the gateway device, the differential data communication link is not actively disconnected. The differential data communication link is connected to the positioning platform device once to achieve continuous transmission of differential data.

[0062] In some embodiments, differential data is generated based on multiple differential reference stations corresponding to the positioning data. Each differential reference station uses its known position to calculate the error between the expected position and the actual observed position of the observed satellite signal and generate multiple differential data. Finally, the multiple differential data are combined to determine the differential data corresponding to the positioning data.

[0063] S105: The gateway device receives the differential data and sends the differential data to the terminal device through the BIP link.

[0064] Among them, the BIP link is a long connection. After the gateway device sends differential data to the terminal device, the BIP link is not actively disconnected. The BIP link is connected to the gateway device once to achieve continuous transmission of differential data.

[0065] S106, the terminal device receives the differential data, and corrects the corresponding positioning data based on the differential data to obtain target positioning data.

[0066] The original positioning data is corrected in combination with the differential data. Through the correction of the differential data, the terminal device can obtain more precise and accurate positioning data.

[0067] First, the positioning data is obtained through the terminal device, and the positioning data is sent to the positioning platform device through the gateway device according to the independent bearer protocol BIP link established between the user identity module SIM card application and the gateway device; the SIM card application and the corresponding independent bearer protocol BIP link are used to ensure the compatibility and interoperability between different devices and networks. The positioning platform device sends the corresponding differential data to the gateway device according to the preset sending frequency based on the received positioning data according to the gateway device; the differential data is actively pushed, and there is no need to wait for the differential data to be pushed after each positioning data is sent, which can increase the frequency of obtaining differential data. The gateway device sends the differential data to the SIM card application of the terminal device. The terminal device receives the differential data sent by the gateway device through the BIP link and corrects the positioning data to obtain the target positioning data. The embodiment of the present application establishes a BIP link and an Internet Protocol connection link, actively pushes differential data according to the preset sending frequency, improves the frequency of obtaining differential data, and improves positioning efficiency.

[0068] In some embodiments, the positioning module of the terminal device encapsulates the positioning data in an Application Protocol Data Unit (APDU) instruction and sends the APDU instruction to a SIM card application of the terminal device;

[0069] The SIM card application parses the structure of the APDU instruction according to the SIM card communication protocol specification, extracts the GGA data content, and sends the GGA data to the gateway device.

[0070] In some embodiments, the SIM card remote management technical specification may be the ETSI TS102 223 specification.

[0071] In some embodiments, when the terminal device sends positioning data to the gateway device, it sends a positioning data sending message to the gateway device. The structure of the positioning data sending message is shown in Table 1.

[0074] In some embodiments, when the gateway device receives the positioning data sent by the terminal device, it sends a positioning data response message to the terminal device. The structure of the positioning data response message is shown in Table 2.

[0081] In some embodiments, after receiving the differential data, the terminal device returns a differential data response message to the gateway device. The structure of the differential data response message is shown in Table 4.

[0083]

[0084] In some embodiments, when the SIM card application establishes an independent bearer protocol BIP link with the gateway device, before the terminal device sends the positioning data to the gateway device, such as Figure 2 As shown, the method may further include: S201 to S202.

[0085] S201, checking whether a BIP link is established between the SIM card application and the gateway device.

[0086] S202: If no BIP link is established, establish a BIP link to a gateway device based on the BIP protocol.

[0087] Before sending positioning data, check whether the BIP link is established to ensure the reliability of data transmission; and establish the BIP link when it is not established to maintain a long connection of the BIP link, avoid invalid data transmission, and improve overall communication efficiency.

[0088] In some embodiments, the method may further include:

[0089] When the terminal device sends positioning data to the gateway device for the first time, the preset sending frequency of the differential data is sent to the gateway device, so that the gateway device sends the preset sending frequency to the positioning platform device, so that the positioning platform device sends the differential data to the gateway device according to the preset sending frequency;

[0090] The gateway device receives a preset sending frequency of differential data sent by the terminal device;

[0091] When the gateway device sends positioning data to the positioning platform device for the first time, the preset sending frequency of differential data is sent to the positioning platform device, so that the positioning platform device sends differential data to the gateway device according to the preset sending frequency;

[0092] The positioning platform device receives the preset sending frequency of the differential data sent by the gateway device, so as to send the differential data to the gateway device according to the preset sending frequency.

[0093] The terminal device sends a preset sending frequency to the positioning platform device through the gateway device, allowing the terminal device to customize the sending frequency of differential data according to actual needs. The terminal device can adjust the sending frequency of differential data of the positioning platform device according to the actual positioning accuracy requirements.

[0094] In some embodiments, the preset transmission frequency of the differential data of each SIM card application may be set to a different value, or a unified default value may be set.

[0095] In some embodiments, when the gateway device sends positioning data to the positioning platform device for the first time, it needs to initiate authentication with the high-precision positioning platform. After the authentication is passed, the gateway device maintains a long connection of the differential data communication link with the positioning platform device, receives the differential data sent by the positioning platform device and sends it to the terminal device. When it is not the first time to send positioning data, the positioning data is sent directly using the differential data communication link long connection without the need for authentication again.

[0096] In some embodiments, the authentication information may include user name and password, differential data preset transmission frequency, satellite mounting point, service level and other information. The authentication information is bound to the SIM card application of the terminal device and is configured and saved by the gateway device.

[0097] In some embodiments, after the terminal device receives the differential data sent by the gateway device through the BIP link, Figure 3 As shown, the method may further include: S301 to S303.

[0098] S301, writing differential data into a preset first memory area;

[0099] S302, determining whether the preset second memory area state is an unread state;

[0100] S303, when the second memory area is in an unread state, copy the differential data written in the first memory area to the second memory area.

[0101] In the prior art, when the terminal reads the differential data in the SIM card application cache, when the differential data arrives from the platform, the differential data is large, usually about 1K bytes, and the differential data often exceeds the maximum effective data transmission size of 255 bytes of the Application Protocol Data Unit (APDU) instruction. Therefore, there is a situation of segmented reading, and multiple instructions are required for writing. If differential data arrives and needs to be updated during the segmented reading instruction process, there is a possibility that the new and old differential data are confused when reading and writing the same differential data storage area.

[0102] The first memory area is used as a cache area to temporarily store the differential data received from the gateway device; the differential data write operation is separated from the read operation to improve the efficiency and reliability of data access. It ensures that new differential data will not be written by mistake before the old differential data is read and processed, avoiding data overwriting problems.

[0103] In some embodiments, the first memory area and the second memory area are memory areas of the SIM card application, the status of the second memory area may include unread, reading, and read, and the status of the first memory area may include unwritten, writing, and written.

[0104] In an example, the specific steps of writing the differential data into the first memory area and the second memory area may include:

[0105] When the first write instruction arrives, the first segment written into the first memory area is updated first, and the status of the first memory area is updated to being written;

[0106] When the second instruction arrives, the second segment of the first memory area is updated, and after the last instruction is written, the status of the first memory area is updated to written;

[0107] Determine whether the status of the second memory area is in the reading state. If it is in the unread or read state, copy the entire content written in the first memory area to the area of ​​the second memory area, and update the status of the second memory area to unread, update the first memory area to the unwritten state, and end the writing process; if it is in the reading state, in order to ensure that the read data is not confused, the writing process is ended at this time.

[0108] When the terminal device needs to read differential data, there is also the problem of reading a maximum of 255 bytes, so the terminal device also needs to split and read the differential data.

[0109] In an example, the specific steps of reading the differential data from the second memory area may include:

[0110] When the first read instruction arrives, the first segment (255 bytes) in the second memory area is read, and the read status is updated to reading;

[0111] When the second read instruction arrives, the second segment of the second memory area is read, and the read status is updated to read after the last read instruction is read;

[0112] Determine whether the state of the first memory area is written. When it is written, copy the written data of the entire first memory area to the second memory area, update the state of the second memory area to unread, update the first memory area to the unwritten state again, and end the reading process; when the state of the first memory area is unwritten, end the reading process.

[0113] In some embodiments, when the gateway device establishes a differential data communication link with the positioning platform device, before the gateway device sends positioning data to the positioning platform device, Figure 4 As shown, the method may further include: S401 to S402.

[0114] S401, checking whether a differential data communication link is established between the gateway device and the positioning platform device;

[0115] S402: If a differential data communication link is not established, establish a differential data communication link connected to the positioning platform device based on a differential data communication protocol.

[0116] Before sending positioning data, check whether the differential data communication link is established to ensure the reliability of data transmission; and establish the differential data communication link when it is not established to avoid invalid data transmission and improve the overall communication efficiency.

[0120] The receiving module 503 is used to receive the differential data sent by the gateway device through the BIP link;

[0121] The correction module 504 is used to correct the corresponding positioning data based on the differential data to obtain target positioning data.
