Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

The embodiment of the application provides a satellite signal acquisition method, a device, equipment and a storage medium based on a user identification card, which can be applied to satellite signal transmission; the satellite signal acquisition method based on the user identification card integrates a satellite signal receiving chip on the user identification card, namely, the integrated satellite signal receiving chip and the identification card chip are integrated into a whole, and satellite signals are transmitted through the user identification card; therefore, the satellite signal acquisition method based on the user identification card has the technical effects that the identification card chip and the satellite signal receiving chip form an integrated device, the satellite signal received by the satellite signal receiving chip is transmitted based on the user identification card, and the satellite navigation positioning function can be achieved through the user identification card.

It should be understood that the Subscriber Identity Module (SIM) card described in the embodiments of the present application is an IC card held by a mobile Subscriber of the GSM system, and is also called a Subscriber Identity Module (SIM) card. The GSM system identifies the GSM subscriber by means of a SIM card. The same SIM card can be used on different mobile phones. The GSM mobile phone can be accessed to the network only after the SIM card is inserted. The SIM card is the key for the GSM handset to connect to the GSM network, and once the SIM card is removed from the handset, the handset cannot enjoy various services provided by the network operator except for emergency calls. The SIM card, in addition to being able to act as a key, also provides a lot of convenience for the user. The user can realize communication only by inserting or embedding the SIM card into any GSM terminal. The SIM card also manages a lot of information that is provided to the user's services and can be used to store short messages, especially those received when the user is not powered on or is not present.

Referring to fig. 1a, fig. 1a is a schematic flowchart of a method for acquiring a satellite signal based on a subscriber identity module card according to an embodiment of the present application, where the method for acquiring a satellite signal based on a subscriber identity module card includes the following steps:

s100: after the user identification card is inserted into the card seat or the interface equipment, the contact point of the user identification card is connected;

s200: sending a reset signal to the user identification card and establishing communication with the user identification card;

s300: and acquiring a combined data packet sent by the user identification card, wherein the combined data packet comprises a satellite signal resolving result.

In some embodiments, the satellite signal acquisition method based on the subscriber identity module transmits the satellite signal through the subscriber identity module by integrating a satellite signal receiving chip on the subscriber identity module, i.e. integrating the satellite signal receiving chip and the identity module into a whole; therefore, the satellite signal acquisition method based on the user identification card has the technical effects that the identification card chip and the satellite signal receiving chip form an integrated device, the satellite signal received by the satellite signal receiving chip is transmitted based on the user identification card, and the satellite navigation positioning function can be achieved through the user identification card.

Referring to fig. 1b, fig. 1b is a schematic flowchart of another method for acquiring satellite signals based on a subscriber identity module card according to an embodiment of the present application, where the method for acquiring satellite signals based on a subscriber identity module card includes the following steps:

s100: after the user identification card is inserted into the card seat or the interface equipment, the contact point of the user identification card is connected;

s200: sending a reset signal to the user identification card and establishing communication with the user identification card;

s301: sending a communication execution instruction to a user identification card;

s302: and acquiring the merged data packet sent by the user identification card based on the communication execution instruction.

For example, the subscriber identity card may send the merged data packet based on the communication execution instruction, or may send the merged data packet autonomously, that is, in a regular or irregular manner, which is not limited herein.

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a calculation result of processing satellite signals by a subscriber identity card according to an embodiment of the present disclosure.

Exemplarily, S300: before the step of obtaining the merged data packet sent by the subscriber identity card, the subscriber identity card performs the following processes:

s310: the identification card chip sends a reset signal to the satellite signal receiving chip;

s310: a satellite signal receiving chip loads a satellite navigation positioning task;

s330: the satellite signal receiving chip resolves the satellite signal according to the satellite navigation positioning task and obtains a satellite signal resolving result;

s340: the satellite signal receiving chip periodically sends a satellite signal resolving result to the identification card chip.

Optionally, the satellite signal receiving chip may send the satellite signal calculation result to the identification card chip periodically or aperiodically, or may send the satellite signal calculation result to the identification card chip based on the communication instruction, which is not limited herein.

For example, taking a UART (Universal Asynchronous Receiver/Transmitter) serial port as an example, the satellite signal receiving chip (or die) is in circuit connection with the identification card chip (or die); the circuit connection between the satellite signal receiving chip (or die) and the identification card chip (or die) may also be in other interface forms such as SPI (Serial peripheral interface), I2C, GPIO (General-purpose input/output), and the like, which is not limited herein.

In some implementation scenarios, the card-using process of the subscriber identity card (i.e. SIM card) is divided into:

1) inserting the SIM card into the card holder (interface device) and connecting each contact point;

2) resetting the SIM card and establishing communication between the terminal and the SIM card;

3) performing communication (reading and writing the SIM card);

4) the contacts are released and the SIM card is removed.

Illustratively, when the SIM card is inserted into the card socket, but the contacts have not made physical contact yet, the terminal must ensure that all contacts are in a low state. When the direction of insertion of the SIM card is put in, the interface device of the socket should be able to detect whether it is positioned in the standard correct position, and when the interface device of the socket detects that the SIM card is in this correct position (within the required range) and all contacts are already in contact, it is activated.

Illustratively, the terminal needs to remain reset to a low state throughout the activation process.

For example, after the contacts are physically closed, VCC (voltage supply for the circuit), i.e. the supply voltage for the subscriber identity card, should be energized before the contacts are clocked again.

Illustratively, after a Central Processing Unit (CPU) of the terminal confirms that VCC is stabilized within a reasonable voltage range, the terminal sets an IO line as a receiving mode, provides a specified stable clock, and stabilizes VCC after a sufficient waiting time;

for example, after the relevant reset operation is performed on the card, the selection of the application according to the SIM card and the subsequent information exchange between the SIM card and the terminal, such as the read-write operation required by various applications, may be referred to as "performing a transaction".

For example, whether the transaction is normal or the IO is abnormally ended, the terminal must release the interface device of the card socket in certain steps; the terminal starts to release the contact by setting the reset signal to be in a low level state; after the reset signal is set to be in a low level state and before the VCC is powered off, the terminal sets the clock and the IO line to be in a low level; before the contacts are actually opened, the terminal must de-energize the VCC, which is at a well-defined low level (e.g., ≦ 0.4V) between the actual opening of the contacts of the card socket interface device.

Exemplarily, S300: after the step of obtaining the merged data packet sent by the subscriber identity card, the method further comprises:

releasing the contact point of the subscriber identity card.

Illustratively, after the SIM card is normally inserted into the card socket and the contacts are physically connected, whether before or after the clock is activated, as long as the VCC is powered up and stable, at this time, the satellite navigation positioning chip has already started to perform the power-on startup procedure.

Illustratively, also, when the VCC is normally powered up, the identification chip starts to be powered up, and when the SIM card is normally activated, that is, the identification chip can normally operate.

Exemplarily, when the identification chip is started normally, the satellite navigation positioning chip is reset and released; when the reset of the satellite navigation positioning chip is released, the satellite navigation positioning chip can be continuously started to enter a normal application state; the identification chip is also supported not to reset the satellite navigation positioning chip (pin is left empty), and at the moment, as long as VCC is electrified normally, the satellite navigation positioning chip can be started by itself and enters a normal application state.

Exemplarily, under the condition that the satellite signal is satisfied, the satellite navigation positioning chip resolves the captured satellite signal, and after normal resolving, the satellite navigation positioning data is periodically output to a serial port.

For example, the identification chip may periodically obtain satellite navigation positioning information from the serial port, and may send the satellite navigation positioning data to the terminal CPU in an uplink manner according to a protocol related to an "Application protocol data Unit" information word chunk, which is described in detail in the following, through an ISO7816 protocol.

Illustratively, the embodiments of the present application provide two protocol types: character transmission protocol and block transmission protocol, one of them must be supported by SIM card, and two protocols must be supported by terminal CPU at the same time. The protocol used for subsequent communication between the SIM card and the terminal needs to be specified first. It should be understood that the embodiment of the present application takes the block transmission protocol as an implementation scheme for illustration, and does not limit the implementation scheme; implementations may also employ a character transfer protocol.

TABLE 1

See Table 1, where bit 2:0 of NAD indicates the source address of the block word group, bit 6:4 indicates the destination address pointed to by the block word group, bit 3, bit 7 are unused and set to 0; the EDC, i.e., the tail field, contains the Error Detection Code (EDC) of the transmitted word, and the word is invalid when a parity Error or EDC Error occurs.

Illustratively, the PCB protocol control word encodes the type of the data block, including three types: first is the information word used to transmit APDUs; a receive ready block for communicating an acknowledgement or a negative acknowledgement; and thirdly, a management block for exchanging data information.

Illustratively, the LEN length information refers to the length of INF (information field) of the block, and the value range is 2-254 bytes; wherein, INF is an information field, which may be application data; or may be control information; the APDU is an application protocol data unit, and its structure is as follows (table 2):

command categories	Instruction code	Instruction additional parameters	Command attachment parameters	Maximum length of data
					CLA	INS	P1	P2	P3

TABLE 2

See table 2, where P3 is encoded by the INS to indicate either the length of data sent to the SIM card in the command or the maximum length of data waiting for a response from the SIM card.

In some embodiments, as an example, a user information file, 01B0810006, command 0x01, command code 0xB0, P1 command parameter 0x81 is read; the P2 command parameters are 0x00, and the data length is 0x 06; the code of the response, 0000001740019000, refers to a 6 byte user ID: 000000174001.

in some embodiments, as an example, the navigation positioning information file, 01B0880110, command 0x01, command code 0xB0, P1 command parameter 0x88 is read; the P2 command parameters are 0x01, and the data length is 0x 10; the code of the response is 785370125DF4CA28668F862064CD68E79000 as follows, which refers to a navigation positioning information file with 16 bytes: 785370125DF4CA28668F862064CD68E 7.

For example, by customizing different instruction codes and instruction additional parameters, the original ISO7816 protocol can be extended, so that the transmission of satellite navigation positioning information is increased.

In the inf (information field) field of the chunk of the information word of the APDU and delivered by the TTL to the SIM card, if the APDU is too long to fit into one block, it can be connected in several blocks as follows (table 3):

TABLE 3

Referring to Table 3, where Le is the length in bytes, P3 must be set to 00.

For example, after receiving the satellite navigation positioning data, the terminal CPU may perform corresponding processing according to the requirements of the upper layer application.

In some embodiments, S300: after the step of obtaining the merged data packet sent by the subscriber identity card, the method further comprises:

and acquiring satellite navigation positioning setting and display information according to a preset APP and a combined data packet.

For example, the terminal CPU may open up a dedicated APP application and a corresponding APP interface, so as to be dedicated to some specific settings of satellite navigation positioning and applications such as display of navigation positioning.

Exemplarily, S300: the step of acquiring the merged data packet transmitted by the subscriber identity card comprises the following steps:

and acquiring a merged data packet sent by the user identification card based on the communication execution instruction based on an asynchronous half-duplex character transmission protocol or an asynchronous half-duplex block transmission protocol.

Further, the merged data packet sent by the user identification card based on the communication execution instruction is acquired based on the ISO7816 protocol or the extension protocol thereof.

Illustratively, the two protocol types, the character transfer protocol and the block transfer protocol, the SIM card must support one of them, and the terminal CPU must support both protocols. The protocol used for subsequent communication between the SIM card and the terminal needs to be specified first. Optionally, a block transfer protocol is used as an implementation scheme.
