[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1 , Figure 1 It is a schematic diagram of the architecture of an existing terminal. The existing positioning method is applied to the terminal 10. The terminal 10 includes a positioning module 110, a microcontroller 120 (MCU) and a communication module 130. The subscriber identification card 1301 (SIM) is arranged in the communication module 130. The positioning process is as follows: 1. The MCU 120 obtains the approximate location data from the positioning module 110; 2. The MCU 120 sends the approximate location data to the SIM card 1301 in the communication module 130; 3. The MCU 120 obtains differential data from the SIM card 1301 side: The SIM card 1301 sends the approximate location data to the positioning platform 60 through the BIP gateway 50 based on the BIP protocol, such as the One Point platform, One Point. nt platform calculates differential data and returns it to SIM card 1301. MCU120 periodically obtains the differential data from SIM card 1301. 4. MCU120 obtains precise location data: MCU120 forwards differential data to positioning module 110. Positioning module 110 calls the solution algorithm to calculate precise location data based on differential data. It can be seen that MCU120 needs to interact with positioning module 110 and communication module 130 for multiple times before it can obtain precise location data. The complexity of MCU implementation is relatively high, which is difficult for terminal manufacturers to develop and has certain development costs.

[0036] Based on this, an embodiment of the present invention provides a positioning method, see Figure 2 , Figure 2 1 is a flow chart of a positioning method provided by an embodiment of the present invention. Specifically, the positioning method is applied to a terminal, the terminal includes a positioning function module, a solution module and a user identification card, and the positioning method includes steps S11 to S14:

[0041] In one example, see Figure 3 , Figure 3 : is a flow chart of a positioning method provided by an embodiment of the present invention. The terminal includes a positioning function module, a solution module, a SIM card, an MCU and a communication module. The specific flow of the positioning method is as follows:

[0042] 1. The MCU initiates a precise positioning request to the positioning function module, requesting precise location data.

[0043] 2. The positioning function module obtains positioning related data (the positioning related data includes initial positioning information, and the initial positioning information can be GGA data), and generates related APDU instructions; wherein, GGA is a data output format statement of the Global Positioning System (GPS), is the main data of a frame of GPS positioning, and is one of the most widely used data in the unified RTCM standard protocol (National Marine Electron Association, NMEA) format of GPS navigation devices; APDU's full name in English is Application Protocol Data Unit, and in Chinese it is Application Protocol Data Unit. In this embodiment, APDU is a basic information unit used to transmit commands and responses between the positioning function module and the SIM card.

[0044] 3. The positioning function module initiates a positioning data transmission request to the SIM card and sends the APDU command carrying GGA and other data to the SIM card side.

[0045] 4. The SIM card returns a command response and establishes a BIP link with a gateway (BIP gateway) that uses the Bearer Independent Protocol (BIP).

[0046] 5-1. The SIM card sends a differential data request carrying initial positioning information and other data to the BIP gateway based on the BIP protocol; 5-2. The BIP gateway forwards the differential data request to the high-precision positioning platform.

[0047] 6. The high-precision positioning platform calculates the differential data based on the initial positioning information carried in the differential data request.

[0048] 7-1. The high-precision positioning platform responds with differential data and sends the differential data to the BIP gateway; 7-The BIP gateway responds with differential data and feeds the differential data back to the SIM card.

[0049] 8. The SIM card stores differential data for high-precision positioning.

[0050] 9-1. The positioning function module periodically sends a differential data acquisition instruction to the SIM card side in APDU format; 9-2. The SIM card responds to the differential data acquisition instruction and sends the differential data to the positioning function module.

[0051] 10-1. The positioning function module initiates a precise position calculation request to the solution module, and sends the differential data and data required for precise positioning to the solution module for solution; wherein, the data required for precise positioning is the data required for calculating the precise position data determined based on the positioning-related data, such as the original observation data and other data; 10-2. The solution module calculates the precise position data based on the original observation data and the differential data; 10-3. The solution module makes a precise position response and sends the precise position data to the positioning function module.

[0052] 11. After the positioning function module obtains the precise location data, it responds with the precise location data and sends the precise location information to the MCU.

[0053] In another example, see Figure 4 , Figure 4 FIG. 1 is a flow chart of another positioning method provided by an embodiment of the present invention. The specific flow of the positioning method is as follows:

[0054] 1. The MCU initiates a precise positioning request to the positioning function module, requesting precise location data.

[0055] 2. The positioning function module obtains positioning related data (for example, the positioning related data is original observation data).

[0056] 3. The positioning function module calculates GGA data based on the original observation data.

[0057] 4. The positioning function module generates relevant APDU instructions based on GGA data.

[0058] 5. The positioning function module initiates a positioning data transmission request to the SIM card and sends the APDU command carrying GGA and other data to the SIM card side.

[0059] 6-1. The SIM card responds to the command, initiates a differential data request to the high-precision positioning platform, and sends the APDU command to the high-precision positioning platform; 6-2. The high-precision positioning platform calculates the differential data; 6-3. The high-precision positioning platform responds to the differential data and sends the differential data to the SIM card.

[0060] 7. The SIM card stores the differential data.

[0061] 8. The positioning function module sends a differential data acquisition instruction to the SIM card side in APDU format.

[0062] 9. The SIM card responds to the differential data acquisition instruction and sends the differential data to the solution module.

[0063] 10-1. The positioning function module initiates a precise position calculation request to the solution module, and sends the original observation data to the solution module for solution; wherein, the data required for precise positioning is the data required for calculating the precise position data determined based on the positioning-related data, such as the original observation data and other data; 10-2. The solution module calculates the precise position data based on the original observation data and the differential data; 10-3. The solution module makes a precise position response and sends the precise position data to the positioning function module.

[0064] 11. After the positioning function module obtains the precise location data, it responds with the precise location data and sends the precise location information to the MCU.

[0065] It is understandable that in Figure 3 and Figure 4 In the corresponding example, the MCU only needs to interact with the external module once to obtain the precise location data of high-precision positioning, which reduces the difficulty and cost of MCU development. Based on the positioning method, it can provide low-cost terminal manufacturers with an integrated high-precision positioning module. Terminal manufacturers do not need to do too much development work on the MCU to use high-precision positioning services.

[0066] It is understandable that when the positioning-related data does not include the initial positioning information, for example, when the positioning-related data is original observation data, the initial positioning information (such as Figure 4 As shown), the positioning function module may also send the positioning-related data to the SIM card, and the SIM card may calculate the initial positioning information based on the original observation data. That is, when the positioning-related data does not include the initial positioning information, the operation of calculating the initial positioning information based on the positioning-related data may be performed by the positioning function module or by the SIM card, which is not specifically limited herein.

[0067] Compared with the prior art, the embodiments of the present invention reduce the number of times the microcontroller unit participates in data interaction by directly performing data interaction between the user identification card and the target module (positioning function module and / or solution module), avoids excessive implementation complexity of the microcontroller unit, and thus reduces the difficulty of research and development.

[0068] In a preferred embodiment, a first interface is provided between the user identification card and the positioning function module, for realizing data transmission between the user identification card and the positioning function module;

[0069] A second interface is provided between the positioning function module and the solution module, for realizing data transmission between the positioning function module and the solution module;

[0070] A third interface is provided between the micro control unit and the positioning function module, for realizing data transmission between the micro control unit and the positioning function module.

[0071] Specifically, see Figure 5 , Figure 5 2 is a schematic diagram of the architecture of a terminal provided by an embodiment of the present invention. Taking the terminal as an Internet of Things terminal 20 as an example, the Internet of Things terminal 20 includes a positioning function module 211, a solution module 212, a SIM card 213, an MCU 220 and a communication module 230. The positioning function module 211, the solution module 212 and the SIM card 213 can form an integrated high-precision positioning module 210. Figure 3 The method steps shown can be applied to Figure 5In the terminal, a first interface IF1 is newly added between the positioning function module 211 and the SIM card 213, and the first interface IF1 is used to transmit initial positioning information, differential data, etc. A second interface IF2 is provided between the positioning function module 211 and the solution module 212, and the second interface IF2 can be used to transmit differential data, positioning-related data, precise location data, etc. A third interface IF3 is provided between the MCU220 and the positioning function module 211, and the third interface IF3 is used to transmit precise location data, precise positioning request data, etc. A fifth interface IF5 is provided between the SIM card 213 and the communication module 230, and is used to transmit initial positioning information, differential data, etc.

[0072] In this embodiment, the MCU initiates a precise positioning request to the positioning function module through the third interface. The positioning function module responds to the request and sends initial positioning information to the SIM card through the first interface. The SIM card sends the initial positioning information to the positioning platform, receives the differential data fed back by the positioning platform and feeds it back to the positioning function module through the first interface. The positioning function module sends the data required for precise positioning and the differential data to the solution module through the second interface to calculate the precise position data. The solution module feeds back the precise position information to the positioning function module through the second interface, and the positioning function module feeds back the precise position information to the MCU through the third interface. In the above process, the MCU does not need to interact with other modules multiple times, avoiding the high complexity of the implementation of the microcontroller unit, thereby reducing the difficulty of research and development.

[0073] In a preferred implementation, a fourth interface is provided between the solution module and the user identification card for implementing data transmission between the solution module and the user identification card.

[0074] Specifically, see Figure 6 , Figure 6 2 is a schematic diagram of the architecture of another terminal provided by an embodiment of the present invention. Taking the terminal as an Internet of Things terminal 20 as an example, the Internet of Things terminal 20 includes a positioning function module 211, a solution module 212, a SIM card 213, an MCU 220 and a communication module 230. The positioning function module 211, the solution module 212 and the SIM card 213 can form an integrated high-precision positioning module 210. Figure 3 or Figure 4 The method steps shown can be applied to Figure 6 In the terminal, Figure 6 The terminal shown is Figure 5 On the basis of the terminal architecture shown, a fourth interface IF4 is added between the solution module 212 and the SIM card 213. The fourth interface IF4 can be the original 7816 interface of the SIM card 213, which is used to transmit network authentication data, differential data, positioning related data, etc.

[0075] In this embodiment, the MCU initiates a precise positioning request to the positioning function module through the third interface. The positioning function module responds to the request and sends initial positioning information to the SIM card through the first interface. The SIM card sends the initial positioning information to the positioning platform, receives the differential data fed back by the positioning platform and feeds it back to the positioning function module through the fourth interface. The positioning function module sends the data required for precise positioning to the solution module through the second interface so that the solution module calculates the precise position data based on the data required for precise positioning and the differential data. The solution module feeds back the precise position information to the positioning function module through the second interface, and the positioning function module feeds back the precise position information to the MCU through the third interface. In the above process, the MCU does not need to interact with other modules multiple times, which avoids the high complexity of the implementation of the microcontroller unit, thereby reducing the difficulty of research and development.

[0076] In a preferred implementation, the positioning-related data includes the initial positioning information, or the initial positioning information is calculated by the positioning function module or the user identification card according to the positioning-related data.

[0077] Specifically, the positioning-related data may include but are not limited to original observation data, approximate position data and initial positioning information (such as GGA). When the positioning-related data does not include initial position information, the initial positioning information may be calculated based on the positioning-related data, such as calculating GGA based on the original observation data.

[0078] In a preferred embodiment, the differential data is forwarded by the user identification card directly to the solution module or forwarded to the solution module through the positioning function module in response to a differential data acquisition instruction, and the differential data acquisition instruction is sent by the positioning function module to the user identification card.

[0079] For example, in Figure 5 In the terminal architecture shown, after the positioning function module 211 sends a differential data acquisition instruction to the SIM card 213, the SIM card 213 forwards the differential data to the solution module 212 through the first interface IF1, the positioning function module 211 and the second interface IF2 in sequence. Figure 6 In the terminal architecture shown, after the positioning function module 211 sends a differential data acquisition instruction to the SIM card 213, the SIM card 213 forwards the differential data to the solution module 212 through the first interface, the positioning function module 211 and the second interface IF5 in sequence, or the SIM card 213 directly sends the differential data to the solution module 212 through the fourth interface IF4. Both of the above examples do not require the MCU to forward the differential data, which reduces the number of times the MCU participates in data forwarding, thereby reducing the complexity of MCU implementation and reducing research and development costs.

[0080] In a preferred embodiment, the terminal also includes a communication module, and an independent bearer protocol channel is pre-established between the communication module and the positioning platform; the initial positioning information is sent by the user identification card to the positioning platform through the communication module and the independent bearer protocol channel, and the differential data is fed back to the user identification card by the positioning platform through the independent bearer protocol channel and the communication module.

[0081] Specifically, see Figure 5 and Figure 6 The terminal architecture shown takes the Internet of Things terminal 20 as an example. The Internet of Things terminal 20 also includes a communication module 230. The SIM card 213 interacts with the positioning platform through the communication module 230. Specifically, the BIP protocol can be used to establish a BIP gateway between the communication module 230 and the positioning platform. The SIM card 213 sends the initial positioning information to the positioning platform through the communication module 230 and the BIP gateway in sequence, and the positioning platform feeds back the differential data to the SIM card 213 through the BIP gateway and the communication module 230 in sequence.

[0082] Compared with the prior art, the positioning method provided by the embodiment of the present invention, when the micro control unit initiates a precise positioning request to the positioning function module, after the positioning function module obtains the positioning related data of the terminal, the positioning related data or the initial positioning information determined according to the positioning related data is directly sent to the user identification card, and the data required for precise positioning determined according to the positioning related data is sent to the solution module, and the user identification card sends the initial positioning information determined according to the positioning related data to the positioning platform, without the micro control unit participating in the forwarding of the initial positioning information; the user identification card receives the differential data fed back by the positioning platform according to the initial positioning information, and forwards the differential data to the solution module through the positioning function module or directly sends the differential data to the solution module, without the micro control unit participating in the forwarding of the differential data; finally, the solution module calculates the precise location data of the terminal according to the data required for precise positioning and the differential data, and feeds it back to the micro control unit through the positioning function module, so as to realize the positioning of the terminal. It can be seen that the embodiment of the present invention reduces the number of times the micro control unit participates in data interaction by directly performing data interaction between the user identification card and the target module (positioning function module and / or solution module), avoids the high complexity of the implementation of the micro control unit, and thus reduces the difficulty of research and development.
