Description

Technical Field

[0001] The present application relates to the technical field of communication equipment, and in particular to a user identification card, a mobile terminal and a data interaction method. Background Art

[0002] Satellite navigation currently refers to the use of navigation satellites to provide navigation and positioning services for users on the ground, at sea, in the air, and in space. Examples include the Galileo and Beidou satellite navigation systems. Satellite navigation combines the advantages of traditional navigation systems, enabling truly high-precision, passive global navigation and positioning in all weather conditions. Time-of-range satellite navigation systems, in particular, not only provide continuous, three-dimensional global and near-Earth space coverage, high-precision three-dimensional positioning and velocity measurement, but also exhibit strong anti-interference capabilities.

[0003] With the rapid development of the economy and the rapid advancement of information technology, navigation and positioning in mobile terminals have become a standard feature. Although satellite navigation and positioning have gained widespread adoption, this functionality is typically integrated into the mobile terminal's communication control chip in an IP-based format. Currently, mainstream mobile terminal communication control chips feature a high level of board-level integration and a densely packed component layout. Adding a satellite navigation receiver module requires reserving space within the existing communication control chip's hardware. However, reserving additional space within the limited space of the communication control chip is difficult, increasing design complexity, restrictions, and high costs. Summary of the Invention

[0037] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0038] The embodiment of the present application provides a user identification card, a mobile terminal and a data interaction method, which can be applied to satellite navigation and positioning; the user identification card integrates a satellite signal receiving module and a satellite receiving antenna interface module, and the satellite receiving antenna interface module transmits the satellite signal to the satellite signal receiving module, and the satellite signal receiving module then deciphers the satellite signal and obtains satellite signal result information. After the main control module receives, configures and processes the satellite signal result information, the satellite signal result information is incorporated into the original user identification card communication data, such as text messages, calls and network data services of the number in the user identification card; thereby, the user identification card can be connected to the mobile terminal to realize telecommunication functions, and the satellite signal result information deciphered by the satellite signal receiving module is transmitted to the mobile terminal for subsequent satellite navigation and positioning applications; the user identification card can achieve the technical effect of supporting the newly added satellite navigation and positioning system without modifying the original mobile terminal mainboard hardware solution and without increasing hardware cost constraints.

[0039] See Figure 1 , Figure 1 This is a schematic structural diagram of a user identification card provided in an embodiment of the present application. The user identification card 10 includes a main control module 110 , a satellite signal receiving module 120 and a satellite receiving antenna interface module 130 .

[0040] Exemplarily, the satellite receiving antenna interface module 130 is connected to the satellite signal receiving module 120 .

[0041] Exemplarily, the satellite signal receiving module 120 is used in a satellite navigation system, and satellite signals are used to process contents such as navigation, positioning, and emergency rescue (Beidou); this is not limited here, and the specific processing contents of the satellite signals received by the satellite signal receiving module 120 can be changed as required.

[0042] For example, satellite navigation refers to the technology of using navigation satellites to navigate and locate users on the ground, ocean, air and space. For example, the common Global Positioning System (GPS) navigation, GLONASS satellite navigation system, Galileo satellite positioning system and Beidou satellite navigation system are all satellite navigation.

[0043] Exemplarily, the satellite receiving antenna receives satellite signals and transmits the satellite signals to the satellite signal receiving module 120 via the satellite receiving antenna interface module 130 . The satellite signal receiving module 120 decodes the satellite signals and obtains satellite signal result information.

[0044] Exemplarily, the satellite signal receiving module 120 is connected to the main control module 110. The satellite signal receiving module 120 is used to process satellite signals, solve satellite signals and obtain satellite signal result information. The main control module 110 is used to receive, configure and process the satellite signal result information obtained by the satellite signal receiving module.

[0045] Exemplarily, the satellite signal result information is processed by the main control module 110, and the main control module 110 can receive, configure and process the satellite signal result information calculated by the satellite signal receiving module 120; optionally, the main control module 110 can be connected to the mobile terminal through a card socket to realize the telecommunication function, and transmit the satellite signal result information calculated from the satellite signal receiving module 120 to the mobile terminal, so that the mobile terminal can perform subsequent satellite navigation and positioning applications; when the satellite navigation and positioning used is the Beidou satellite navigation system, Beidou emergency rescue information can also be received.

[0046] For example, when the user identification card 10 is applied to a mobile terminal and the mobile terminal is a mobile phone, the user identification card can easily support new satellite navigation and positioning systems (such as Beidou-3's global services and Beidou's emergency rescue) and other services without modifying the original mobile phone motherboard hardware solution and increasing the hardware cost restrictions of the mobile phone manufacturer.

[0047] In some implementation scenarios, the user identification card 10 integrates a satellite signal receiving module 120 and a satellite receiving antenna interface module 130. The satellite receiving antenna interface module 130 transmits the satellite signal to the satellite signal receiving module 120, and the satellite signal receiving module 120 then decodes the satellite signal and obtains satellite signal result information. After the main control module 110 receives, configures and processes the satellite signal result information, it incorporates the satellite signal result information into the original user identification card communication data, such as text messages, calls and network data services of the number in the user identification card 10; thus, the user identification card can be connected to the mobile terminal to realize telecommunication functions, and the satellite signal result information decoded from the satellite signal receiving module can be transmitted to the mobile terminal for subsequent satellite navigation and positioning applications; the user identification card 10 can achieve the technical effect of supporting the newly added satellite navigation and positioning system without modifying the original mobile terminal motherboard hardware solution and without increasing hardware cost constraints.

[0048] Exemplarily, the subscriber identity card 10 further includes a card substrate, and the satellite signal receiving module 120 and the main control module 110 are integrally packaged on the card substrate.

[0049] For example, the satellite signal receiving module 120 and the main control module 110 are integrally packaged on a card substrate of a user identification card, so that the user identification card has complete satellite navigation and positioning functions and telecommunication communication functions.

[0050] For example, a card substrate is used in a user identification card 10. The substrate is the fundamental material for PCB manufacturing. Typically, it's a copper-clad laminate (CCL). Single- and double-sided printed circuit boards are manufactured by selectively processing holes, electroless copper plating, electroplating, and etching onto the CCL substrate material to create the desired circuit pattern. Another type of multilayer printed circuit board (PCB) is also manufactured using a thin core CCL as the base. Conductive pattern layers and prepregs are alternately laminated and bonded together in a single process, creating interconnections between three or more conductive pattern layers. This layer performs three functions: conducting, insulating, and supporting.

[0051] Optionally, the various modules (main control module 110, satellite signal receiving module 120, and satellite receiving antenna interface module 130) of the user identification card 10 provided in this application are mounted in a multi-frequency satellite navigation receiving chip package, wherein the PAD (pad) is electrically connected to the pins (pins) of the package body by bonding wires. The die on the card substrate is encapsulated in a standardized plastic mold, and the package form can be an LGA array package based on the back of the card substrate.

[0052] Exemplarily, the subscriber identity card further includes a signal interface module 140 . The signal interface module 140 is connected to the main control module 110 . The main control module 110 exchanges data with the mobile terminal via the signal interface module 140 .

[0053] Exemplarily, the subscriber identity card implements data interaction with the mobile terminal via the signal interface module 140 .

[0054] Optionally, the mobile terminal can use a mobile phone of GSM (Global System for Mobile communications), CDMA (Code Division Multiple Access), 3G (3rd-Generation Mobile Communication Technology), 4G (4th-Generation Mobile Communication Technology) or 5G (5th-Generation Mobile Communication Technology) communication network.

[0055] In some embodiments, the Subscriber Identity Module (SIM) card provided in the embodiments of the present application is an IC card held by a mobile user of the GSM system, referred to as a Subscriber Identity Module (SIM). The GSM system identifies GSM users through the SIM card. The same SIM card can be used on different mobile phones. A GSM mobile phone can only be connected to the network and used after inserting the SIM card. The SIM card is the key for a GSM mobile phone to connect to the GSM network. Once the SIM card is pulled out of the mobile phone, the mobile phone will not be able to enjoy the various services provided by the network operator except for emergency calls. In addition to being a key, the SIM card also provides a lot of convenience for the user. The user only needs to insert or embed the SIM card into any GSM terminal to realize communication. The SIM card also manages a lot of information provided to the user for services and can be used to store short messages, particularly those received when the user does not turn on the phone or is not present.

[0056] Exemplarily, the satellite receiving antenna interface module 130 includes a metal contact point, and the satellite receiving antenna is connected to the metal contact point through a feeder coupling manner.

[0057] Exemplarily, after receiving the satellite signal, the satellite receiving antenna transmits the satellite signal to the satellite receiving antenna interface module 130 through the feeder and the metal contact point in sequence.

[0058] Optionally, the metal contact point is not limited to a metal sheet, the feed line is connected to the metal contact point by coupling, and the metal contact point is not limited to a copper sheet, copper foil, or so-called gold fingers.

[0059] Furthermore, the metal contact points are not limited to the bottom, side, or front of the user identification card.

[0060] Exemplarily, the metal contact point is engraved with an asymmetric micro-groove structure or a protrusion structure.

[0061] For example, the metal contact points on the user identification card are engraved with asymmetric micro-groove structures or protrusion structures. When the user identification card is pushed to the bottom of the card holder on the mobile terminal, the micro-convex structure or micro-groove structure of the metal sheet on the card holder and the micro-groove structure and micro-convex structure of the metal contact points on the user identification card are exactly in the same position and can be in close contact.

[0062] Exemplarily, the electrical bonding wires between the satellite receiving antenna interface module 130 and the satellite signal receiving module 120 are PCB wires.

[0063] For example, a printed circuit board (PCB), also known as a printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections between electronic components.

[0064] In some embodiments, the user identification card provided in the embodiments of the present application is installed in a card holder of a mobile terminal; the micro-groove structure or protrusion structure of the metal contact point is not only suitable for the user identification card, but also suitable for the card holder of the user identification card.

[0065] In some embodiments, the electrical bonding wires between the satellite receiving antenna interface module 130 and the satellite receiving antenna may also be PCB wires.

[0066] In some embodiments, the microgroove structure is formed on the metal contact point formed by the metal sheet by etching, drilling, photolithography, electron etching or ion etching.

[0067] In some embodiments, a contact point is provided between the satellite receiving antenna interface module 130 and the metal sheet on the mobile terminal card holder, and the contact point realizes the electrical lead between the card holder and the user identification card; optionally, when the user identification card is pushed to the bottom of the card holder, the micro-convex structure or micro-groove structure of the metal sheet on the card holder and the micro-groove structure and micro-convex structure of the metal sheet on the user identification card are exactly in the same position and can be in close contact.

[0068] In some embodiments, the micro-convex structure or micro-groove structure of the metal sheet on the card holder and the micro-groove structure of the metal sheet on the user identification card that can be in close contact can be on the side, bottom, or combined surface of the card holder and the user identification card.

[0069] In some embodiments, the electrical bonding wires between the card holder metal sheet and the satellite receiving antenna may be flexible PCB wires.

[0070] In some embodiments, the mobile terminal is a mobile phone, and the user identification card provided in the embodiment of the present application is installed in the mobile phone; optionally, the antenna of the flexible PCB lead can be attached to the inner side of the mobile phone housing.

[0071] See Figure 2 , Figure 2 This is a structural diagram of a mobile terminal provided in an embodiment of the present application, which includes a satellite receiving antenna 20, a card holder 30, Figure 1 The user identification card 10 and the terminal main processor 40 are shown.

[0072] Exemplarily, the satellite receiving antenna 20 is connected to the satellite receiving antenna interface module 130 in the user identification card via the card holder 30 , and the user identification card 10 is embedded and installed in the card holder 30 .

[0073] Exemplarily, the terminal main processor 40 and the subscriber identification card 10 perform interactive communication via a connection line of the card holder 30 .

[0074] Exemplarily, the card holder 30 is provided with a card holder metal sheet, and the electrical bonding wires between the card holder metal sheet and the satellite receiving antenna 20 are flexible PCB wires.

[0075] Exemplarily, the flexible PCB leads are attached to the inner side of the housing of the mobile terminal.

[0076] By way of example, the mobile terminal device provided in the embodiments of the present application includes, but is not limited to, a terminal main processor 40, a card holder 30, a satellite receiving antenna 20, a first connecting line 51 between the terminal main processor 40 and the card holder 30, and a second connecting line 52 between the satellite receiving antenna 20 and the card holder 30. The terminal main processor 40 communicates with the user identification card via the first connecting line 51 between the terminal main processor 40 and the card holder 30 in accordance with the ISO7816 standard (not limited to this standard), including controlling and configuring the main control module 110 in the user identification card 10, and receiving and processing communication data sent by the main control module 110.

[0077] Illustratively, the main control module 110 is the SIM main control chip in the subscriber identity card 10 .

[0078] For example, the terminal main processor 40 receives and processes the communication data sent by the SIM main control chip, including but not limited to sending and receiving text messages, calls and network data services of the number in the user identification card 10.

[0079] Exemplarily, the terminal main control processor receives and processes the result information of the satellite positioning signal calculated by the satellite signal receiving module sent by the SIM main control chip, and performs subsequent satellite navigation and positioning applications.

[0080] Exemplarily, the terminal main processor 40 communicates data via an interface with the card holder 30 through the first connecting line 51, which complies with but is not limited to the ISO7816 data input and output protocol. At the same time, the connecting line interface includes the power supply of the user identification card 10, power grounding, the reset signal of the user identification card 10, the clock signal of the user identification card 10, etc.

[0081] For example, the power supply to the user identification card 10 is not limited to one specification, and can be powered by 1.8V, 3.3V, 5V and other specifications; at the same time, the power supply to the user identification card 10 is not limited to one specification of power driving capability, and can be 20mA, 30mA, 50mA and the like.

[0082] Exemplarily, the first connecting line 51 between the terminal main processor 40 and the card holder 30 can be a PCB trace, a flat cable, a connecting pin, a connecting socket, etc.; it should be understood that the type of the first connecting line 51 is only an example and not a limitation, and the first connecting line 51 can also adopt other connecting line types.

[0083] Exemplarily, the satellite receiving antenna 20 may be a flexible antenna, a ceramic antenna, a surveying antenna, an active antenna, or a passive antenna. It should be understood that the type of the satellite receiving antenna 20 is merely an example and not a limitation, and the satellite receiving antenna 20 may also adopt other antenna types.

[0084] Exemplarily, the satellite receiving antenna 20 may be a high-voltage or low-voltage antenna, and there is no limitation on the specifications and dimensions of the antenna.

[0085] Exemplarily, the satellite receiving antenna 20 may be a left-hand polarized antenna or a right-hand polarized antenna, and may also be an antenna for a single satellite frequency or an antenna for multiple satellite frequencies, which is not limited here.

[0086] For example, the electrical bonding leads of the first connecting line 51 between the terminal main processor 40 and the card holder 30 and the second connecting line 52 between the satellite receiving antenna 20 and the card holder 30 can be coaxial shielded wires, soft PCB leads, or other forms of connecting wires; the various leads are only for the convenience of describing the connection relationship between the two, and do not require that this application must be in a specific form, material or structure, and therefore should not be understood as a limitation on the first connecting line 51 and the second connecting line 52 of this application.

[0087] See Figure 3 , Figure 3 A flow chart of a data interaction method provided in an embodiment of the present application, which is applied to Figure 1 In the user identification card shown, the satellite signal receiving module is a Beidou navigation module, and the data interaction method includes the following steps:

[0088] S100: Receive satellite signals and Beidou emergency rescue information;

[0089] S200: Obtain satellite signal result information according to the satellite signal;

[0090] S300: Processing the communication data of the user identification card, satellite signal result information, and Beidou emergency rescue information according to a preset data input and output protocol to obtain a user identification card data packet;

[0091] S400: Sending the subscriber identity card data packet to the terminal main processor of the mobile terminal.

[0092] For example, the data interaction method provided in the embodiment of the present application is applied to Figure 1 The user identification card shown and Figure 2In the data interaction between the mobile terminals shown, the satellite signal receiving module 120 in the user identification card processes the satellite signal, performs calculations and outputs relevant satellite signal result information, and hands it over to the main control module 110 for processing. The main control module 110 receives, configures and processes the satellite signal result information calculated by the satellite signal receiving module 120, connects to the mobile terminal through the card holder 30 to realize the telecommunication function, and transmits the satellite signal result information calculated by the satellite signal receiving module to the terminal main processor 40 of the mobile terminal for subsequent satellite navigation and positioning applications.

[0093] Optionally, the terminal main processor 40 communicates with the user identification card through the first connection line 51 between the terminal and the card holder 30 in accordance with the ISO7816 standard (not limited to this standard), including controlling and configuring the main control module 110 in the user identification card 10, and receiving and processing the user identification card data packet sent by the main control module 110.

[0094] For example, if a traditional mobile phone satellite navigation receiver wants to add a Beidou satellite navigation receiving module, it is necessary to reserve an area in the original mobile phone's hardware solution to provide for the satellite navigation receiving module. In addition to the main control chip, the mobile phone also has chips for WiFi, Bluetooth, power supply, motor, camera and many other functions. The board-level integration is very high and the component layout is already very dense. It is already difficult to reserve more space in a limited space, which will also increase the design difficulty.

[0095] The user identification card, mobile terminal, and corresponding data interaction method provided in the embodiments of the present application are as follows: the user identification card integrates a satellite signal receiving module 120 and a satellite receiving antenna interface module 130, wherein the satellite receiving antenna interface module 130 transmits satellite signals to the satellite signal receiving module 120, and the satellite signal receiving module 120 then interprets the satellite signals and obtains satellite signal result information. After receiving, configuring, and processing the satellite signal result information, the main control module 110 incorporates the satellite signal result information into the original user identification card communication data, such as text messages, calls, and network data services of the number in the user identification card; thus, the user identification card can be connected to the mobile terminal to implement telecommunication functions, and the satellite signal result information interpreted by the satellite signal receiving module can be transmitted to the mobile terminal for subsequent satellite navigation and positioning applications; the user identification card can achieve the technical effect of supporting the newly added satellite navigation and positioning system without modifying the original mobile terminal motherboard hardware solution and without increasing hardware cost constraints.
