[0081] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0082] The embodiment of the present application provides an information transmission method, which is applied to a gateway, such as Figure 1 As shown, the method includes:

[0083] Step 101: Send differential data to a user identity card of a terminal, where the differential data is used to locate the terminal.

[0084] In actual application, the gateway actively pushes differential data to the user identity identification module (Subscriber Identification Module, SIM) card of the terminal, realizing the active push of differential data from the gateway to the card side. It should be noted that in the related art, the SIM card obtains differential data in the following way: the gateway receives the differential data sent by the positioning platform, and then sends the differential data to the card side. The differential data is returned as a response to the Hypertext Transfer Protocol (HTTP) message message of a specific format data request (such as Global Positioning System Fix Data, GGA request); however, if the delay between the gateway and the positioning platform is large, it will directly affect the overall delay. It can be seen that the method of actively pushing from the gateway to the card side in this application shortens the push cycle of differential data and reduces the delay compared to the method of returning differential data as a response in the related art.

[0085] In actual applications, differential data is used to locate the terminal, and differential data can be used in scenarios such as navigation, map drawing, and astronomical measurement.

[0086] In actual applications, the terminal may be user equipment (UE), such as a mobile phone, a computer, and may also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a smart phone, a personal digital assistant (PDA), a laptop computer, a handheld communication device, a handheld computing device, a satellite wireless device, a wireless modem card, customer premises equipment (CPE) and / or other devices used to communicate on a wireless system.

[0087] Step 102: Receive a first response sent by the user identity card, where the first response is used to indicate that the user identity card has completed writing the differential data.

[0088] In actual application, the SIM card receives the differential data actively pushed by the gateway, stores the differential data and responds, and sends a first response to the gateway, so that the gateway receives the first response sent by the SIM card.

[0089] In actual applications, the SIM card can be a high-precision SIM card or a non-high-precision SIM card. When the SIM card is a high-precision SIM card, it supports the implementation of high-precision positioning requests and ultimately obtains accurate positioning data.

[0090] The information transmission method provided by the present application sends differential data to the user identity identification card of the terminal, and the differential data is used to locate the terminal; receives a first response sent by the user identity identification card, and the first response is used to indicate that the user identity identification card has completed writing the differential data; the method of actively pushing the differential data from the gateway to the card side in the present application is compared with the method of returning differential data as a response in the related art, which shortens the push cycle of the differential data and reduces the delay.

[0091] In a feasible high-precision positioning scenario, the scenario involves the interaction between the terminal, gateway, and high-precision positioning platform, such as Figure 2 As shown, the terminal side includes a microcontroller unit (MCU) 201, a communication module 202, a high-precision positioning module 203 and a high-precision positioning SIM card 204; wherein, the high-precision positioning SIM card 204 includes the following functions: docking with the high-precision positioning platform: the card leads the docking of the terminal with the high-precision positioning platform, and the card number is used as the identity identifier of the high-precision service; high-precision positioning protocol conversion: through the cooperation of the service gateway, the parsing and conversion of the high-precision positioning proprietary protocol is realized; differential data acquisition and storage: the differential data issued by the platform is acquired and stored for the terminal to call and realize the correction of the position data.

[0092] Here, combined Figure 2 and Figure 3 , the process of MCU obtaining differential data is explained, such as Figure 2 As shown, in the related technology, each time the MCU obtains differential data, it needs to go through steps 1 to 8. The MCU obtains approximate location data from the high-precision positioning module; the MCU sends the approximate location data to the communication module; the communication module sends the approximate location data to the high-precision positioning SIM card; the high-precision positioning SIM card performs protocol conversion with the cooperation of the service gateway and initiates a high-precision positioning request; the service gateway obtains differential data from the high-precision positioning platform and sends the differential data to the high-precision positioning SIM card; the high-precision positioning SIM card stores the differential data; the communication module obtains differential data from the high-precision positioning SIM card; the MCU obtains differential data from the communication module; the MCU sends differential data to the high-precision positioning module; the high-precision positioning module calculates and obtains the precise location. Combined with Figure 2 and Figure 3It can be seen that in the related art, it takes at least T1 time for the MCU to obtain differential data each time, wherein the high-precision positioning SIM card (high-precision positioning card application) sends a high-precision positioning request to the high-precision positioning platform, which can be achieved by sending a GGA data send-bit interleaved parity (Bit Interleaved Parity, BIP) request; the high-precision positioning platform calculates the differential data; the high-precision positioning platform sends a differential data push-BIP response (differential data) to the high-precision positioning card application; the high-precision positioning card application stores the differential data; the MCU-Software Development Kit (SDK) obtains the differential data from the high-precision positioning card application.

[0093] In other words, in related technologies, the gateway receives differential data from the positioning platform and then sends it to the card. This differential data is returned as a response to the GGA request message. However, this process of obtaining differential data causes significant latency between the gateway and the positioning platform, which directly affects the overall latency.

[0094] Based on the differential data acquisition process provided in this application, the gateway actively pushes differential data to the SIM card, enabling the active push of differential data from the gateway to the card. With the cooperation of the service gateway, the high-precision positioning SIM card (high-precision positioning card application) can receive differential data sent by the high-precision positioning platform actively pushed by the gateway. In this scenario, the time it takes for the MCU to obtain differential data can be shortened to T2, reducing overall latency.

[0095] In some embodiments, step 101 of sending differential data to a user identification card of a terminal includes:

[0096] A HTTP security request is sent to the user identity card, where the HTTP security request includes the differential data.

[0097] In actual application, the gateway actively pushes differential data to the card side as Hypertext Transfer Protocol Secure (HTTPS) request data to the card application, which not only shortens the delay for the card side to obtain differential data, but also ensures the security of the transmission process.

[0098] The embodiment of the present application provides an information transmission method, which is applied to a communication module of a terminal, such as Figure 4 As shown, the method includes:

[0099] Step 401: receiving a differential data acquisition request sent by a micro control unit of a terminal.

[0100] Step 402: Send a differential data acquisition response to the micro control unit, where the differential data acquisition response includes all differential data.

[0101] In actual application, when the MCU queries the differential data, the communication module obtains all the differential data from the terminal's SIM card and sends them to the MCU together. In this way, the terminal does not need to perform data splicing, thereby shortening the terminal differential data acquisition delay. This application can shorten the network delay and optimize the differential age through the differential data push optimization mechanism.

[0102] In some embodiments, after step 401 of receiving the differential data acquisition request sent by the micro control unit of the terminal, the method further includes:

[0103] Step 1: Send a differential data acquisition request to the terminal's SIM card.

[0104] In actual application, the communication module sends a differential data acquisition request to the SIM card, which can be achieved by sending an Application Protocol Data Unit (APDU) instruction.

[0105] In actual application, after receiving the differential data acquisition request (AT command) sent by the MCU, the communication module can send a differential data acquisition request (APDU command) to the SIM card to obtain differential data.

[0106] Step 2: Receive a second response sent by the SIM card, where the second response is used to indicate that the SIM card has received the differential data acquisition request.

[0107] In actual application, after receiving the APDU command, the SIM card returns a response to the communication module to inform it of the receipt of the APDU command.

[0108] Step 3: Send each get response command to the SIM card in sequence.

[0109] In actual application, this application obtains differential data from the SIM card multiple times through the get response instruction. During the differential data acquisition stage, the communication module can send N get response instructions.

[0110] Step 4: Receive each third response sent by the SIM card for each get response command, each third response includes differential data corresponding to each get response command, and all differential data include differential data corresponding to each get response command.

[0111] In actual application, the communication module sends each get response command to the SIM card in sequence, and the communication module will receive each third response sent by the SIM card for each get response command; for example, if the get response command is sent N times, the communication module will receive the first segment of differential data,...the Nth segment of differential data respectively; finally, the communication module returns the overall differential data consisting of the first segment of differential data,...the Nth segment of differential data to the MCU.

[0112] In a feasible scenario where communication module, MCU and high-precision SIM card are interacting with each other, such as Figure 5 As shown,

[0113] Step 501: The MCU sends a differential data acquisition request (AT command) to the communication module.

[0114] Step 502: The communication module sends a differential data acquisition request (APDU instruction) to the high-precision SIM card application.

[0115] Step 503: The high-precision SIM card application returns a response to the APDU command to the communication module.

[0116] Step 504: The communication module sends a get response instruction to the high-precision SIM card application.

[0117] Step 505: The communication module receives the response (including the first segment of differential data).

[0118] Step 506: The communication module executes the send get response command to the SIM card application multiple times.

[0119] Step 507: The communication module receives responses (including corresponding segment differential data) multiple times.

[0120] Step 508: The communication module executes the send get response instruction to the SIM card application for the Nth time.

[0121] Step 509: The communication module receives a response (including the Nth segment of differential data).

[0122] Step 510: The communication module sends a differential data acquisition response (including all differential data) to the MCU.

[0123] Step 511: The MCU interacts with the solution module / positioning module of the terminal to implement the solution result calculation process and obtain high-precision positioning result calculation.

[0124] This application optimizes APDU instructions, using the Get Response command to obtain differential data multiple times. The communication module then returns the entire differential data to the MCU. Compared to the related art solution where the MCU queries differential data through multiple commands to obtain differential data, this application uses a mechanism to read differential data through the Get Response method and actively pushes differential data, effectively reducing latency.

[0125] The embodiment of the present application provides an information transmission method, which is applied to the SIM card of the terminal, such as Figure 6 As shown, the method includes:

[0126] Step 601: Receive differential data sent by the gateway, and the differential data is used to locate the terminal.

[0127] Step 602: Send a first response to the gateway, where the first response is used to indicate that the SIM card has completed writing the differential data.

[0128] In actual use, the terminal receives all differential data actively pushed by the gateway. The SIM card responds after storing the differential data. Through the cooperation of the service gateway, the high-precision positioning SIM card (high-precision positioning card application) can receive the differential data actively pushed by the gateway from the high-precision positioning platform. In this way, the time it takes for the card-side MCU to obtain differential data can be shortened to T2, reducing overall latency.

[0129] In some embodiments, step 601 of receiving differential data sent by a gateway includes: receiving a HTTP request sent by the gateway, wherein the HTTP request includes the differential data.

[0130] In actual application, the gateway actively pushes differential data to the SIM card side as https request data to the card application, which not only shortens the delay of the card side obtaining differential data, but also ensures the security of the transmission process.

[0131] The embodiment of the present application provides an information transmission method, which is applied to the MCU of the terminal, such as Figure 7 As shown, the method includes:

[0132] Step 701: Send a differential data acquisition request to the communication module of the terminal.

[0133] Step 702: Receive a differential data acquisition response sent by the communication module, where the differential data acquisition response includes all differential data.

[0134] In actual application, when the MCU queries the differential data, the communication module obtains all the differential data from the terminal's SIM card and sends them to the MCU together. In this way, the terminal does not need to perform data splicing, thereby shortening the terminal differential data acquisition delay. This application can shorten the network delay and optimize the differential age through the differential data push optimization mechanism.

[0135] The embodiment of the present application provides an information transmission method, which is applied to the SIM card of the terminal, such as Figure 8 As shown, the method includes:

[0136] Step 801: Receive a differential data acquisition request sent by a communication module of a terminal.

[0137] In actual application, after receiving the differential data acquisition request (AT command) sent by the MCU, the communication module can send a differential data acquisition request (APDU command) to the SIM card to obtain differential data.

[0138] Step 802: Send a second response to the communication module, where the second response is used to indicate that the SIM card has received the differential data acquisition request.

[0139] In actual application, after receiving the APDU command, the SIM card returns a response to the communication module to inform it of the receipt of the APDU command.

[0140] Step 803: Receive each get response command sent by the communication module.

[0141] In actual application, the present application obtains differential data from the SIM card multiple times through the get response instruction. In the differential data acquisition stage, the communication module can send N get response instructions, so the SIM card can receive each get response instruction sent by the communication module.

[0142] Step 804: Send each third response to the communication module for each get response command, each third response includes differential data corresponding to each get response command, and all differential data include differential data corresponding to each get response command.

[0143] In actual application, the communication module sends each get response command to the SIM card in sequence, and the communication module will receive each third response sent by the SIM card for each get response command; for example, if the get response command is sent N times, the communication module will receive the first segment of differential data,...the Nth segment of differential data respectively; finally, the communication module returns the overall differential data consisting of the first segment of differential data,...the Nth segment of differential data to the MCU.

[0144] The embodiment of the present application provides an information transmission method, which is applied to the SIM card of the terminal, such as Figure 9 As shown, the method includes:

[0145] Step 901: receiving a first write request sent by a communication module of a terminal, where the first write request includes first differential data.

[0146] In actual application, the SIM card interacts with the communication module to realize differential data reading and writing. In the process, the differential data can be written into the SIM card by multiple instructions according to the size of the differential data.

[0147] Step 902: Write the first differential data into the first buffer of the SIM card.

[0148] In actual application, the SIM card sets a multi-cache mechanism. For example, the present application can set a dual-cache mechanism, the first cache is used to write differential data, and the second cache below is used to read differential data. The first cache and the second cache realize full data copy.

[0149] Step 903: Copy the first differential data written in the first buffer to the second buffer of the SIM card.

[0150] In actual application, all the search data written into the first cache are copied into the second cache.

[0151] Step 904: Receive a differential data read request sent by the MCU of the terminal.

[0152] Step 905: Read the differential data from the second cache, and send the read differential data to the micro control unit.

[0153] In actual application, when the SIM card receives the differential data read request sent by the MCU, it reads the differential data from the second cache. This application designs a dual-buffer mechanism. Even if the differential data sent is large, it can be divided into multiple instructions according to the size of the differential data to implement the differential data writing to the specific cache of the SIM card, and when reading the differential data, the reading process is implemented from another specific cache. Since the data in the corresponding caches of writing and reading remain consistent, the validity of the data can be maintained; at the same time, it can also avoid the problem in the related art that because the differential data sent is large, due to the limitations of the machine-card interface, the writing and reading of differential data need to be completed through multiple APDU instructions. Therefore, sometimes there will be a problem of read-write conflict when the differential data has not been read yet and new differential data is written to the card side.

[0154] In some embodiments, the above method further includes:

[0155] Receiving a second write request sent by the communication module of the terminal, the second write request including the second differential data; writing the second differential data into the first buffer of the SIM card;

[0156] The flag state of the second cache is read, and if the flag state is a non-read state, the second differential data written in the first cache is copied to the second cache.

[0157] In actual application, while multiple caches (such as double caches) are set based on the SIM card, a flag mechanism is also set to cooperate in solving the problem of large data read and write conflicts. For the second cache used for reading, the SIM card receives the differential data read request sent by the MCU, and in the stage of reading the differential data from the second cache, the flag status of the second cache is updated to reading; after the reading is completed, the flag status is updated to non-reading. It should be noted that when the second cache flag status is non-reading, a full copy of the differential data from the first cache to the second cache is achieved. When the second cache flag status is reading, wait, set a timer, set the status to read once at intervals, until the status becomes non-reading, and a full copy of the differential data from the first cache to the second cache is achieved.

[0158] In some embodiments, after step 904 of receiving the differential data read request sent by the MCU of the terminal, the method further includes: updating the flag state of the second cache to a read state.

[0159] In actual application, for the second cache used for reading, after the SIM card receives the differential data read request sent by the MCU, the flag state of the second cache is updated to the read state in time to avoid large data read and write conflicts.

[0160] In some embodiments, after step 905 of reading the differential data from the second cache, the method further includes: updating the flag state of the second cache to a non-read state.

[0161] In actual application, for the second cache used for reading, after the SIM card returns the differential data to the MCU, the flag state of the second cache is updated to the non-read state in time, and the differential data between multiple caches is fully copied in time.

[0162] In a scenario where a SIM card, communication module and MCU can interact to realize big data reading and writing, such as Figure 10 As shown,

[0163] Step 1001: The communication module sends a differential data write request (including differential data 1) to the first buffer of the SIM card.

[0164] In actual application, the differential data is written by dividing the differential data into multiple instructions according to the size of the differential data.
