[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Application Overview

[0044] Near Field Communication (NFC) technology, with its short-range interaction characteristics, is widely used in mobile payments, smart access control, and other scenarios. However, existing solutions face significant technical bottlenecks. Firstly, hardware compatibility is limited: some low-to-mid-range mobile terminals do not integrate NFC modules due to cost constraints, directly restricting the coverage of NFC functionality. Secondly, standardization is lacking and licensing barriers exist: although card emulation technology exists, its application requires enterprise-level licensing agreements between equipment manufacturers and chip manufacturers, and terminal manufacturers strictly control NFC interface calls. For example, third-party developers must sign commercial agreements and pay high fees to access the Secure Element (SE) or contactless communication module, leading to a surge in cross-platform deployment costs. Furthermore, existing technologies lack adaptability to heterogeneous devices. Terminal manufacturers' differentiated restrictions on tag types (e.g., only supporting payment tags), interface protocols, and security policies force third-party service providers to repeatedly develop for different systems (iOS / Android) and hardware (eSE, HCE, or UICC), further raising the technical threshold.

[0045] To address the aforementioned issues, this embodiment incorporates an NFC module on the phone case. The NFC module on the extended device sends the tag reading result to the phone. The phone parses the tag reading result to obtain the target device's identification information, enabling interaction with the target device. This allows terminals without NFC functionality to support tag reading by integrating an NFC module into the phone case, bypassing the reliance on a wallet app on the mobile terminal and avoiding business negotiations and licensing costs with terminal manufacturers.

[0046] After introducing the basic principles of this application, various non-limiting embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0047] Exemplary System

[0048] Figure 1 The diagram shown is a schematic representation of an implementation environment provided in an embodiment of this application. This implementation environment includes a mobile terminal 110, an extension device 120, and a target device 130; in some cases, it may also include a cloud server.

[0049] Mobile terminal 110 refers to electronic devices with computing and communication capabilities, such as smartphones and tablets. This embodiment takes a smartphone as an example.

[0050] The target device 130 is a physical device that needs to interact with the mobile terminal, covering typical scenarios such as smart cars, computers, and wireless routers. It has an RFID tag embedded on its surface or inside, which stores the unique identification information of the target device (such as device ID and MAC address) and optional additional parameters (such as service type code, access token, and interaction command set).

[0051] The extension device 120 is a control device with a tag reading module, such as a mobile phone case or wearable device. It can be connected to the mobile terminal 110 via wired or wireless means. Its main function is to read RFID tags and transmit the reading results to the mobile terminal 110.

[0052] When the user places the extension device 120 close to the RFID tag of the target device 130, the mobile terminal 110 can read the RFID tag through the extension device 120 and establish a network connection with the target device 130 based on the device identifier in the RFID tag.

[0053] Because NFC has the characteristic of short-range reading, the tag reading action can also be used to trigger cross-device interactions such as device authentication, near-field payment, application flow, and smart home scene linkage. Mobile terminal 110 can obtain operation signals for mobile terminal 110 by parsing the tag reading result, thereby realizing cross-device interaction.

[0054] Exemplary methods

[0055] Figure 2 This is a flowchart illustrating a short-range information transmission method provided in one embodiment of this application. Figure 2 The method described is executed by a mobile terminal, but this application is not limited thereto. For example... Figure 2 As shown, the method includes the following:

[0056] Step S210: Obtain the first target message sent by the extended device; the first target message is used to transmit the reading result of the tag reading module for the radio frequency tag; the radio frequency tag is used to record the identification information of the target device.

[0057] In the embodiments of this application, the mobile terminal may be an electronic device with computing and communication capabilities, including smartphones, tablets, smartwatches, etc., but the embodiments of this application are not limited thereto.

[0058] In this application embodiment, the target device may include an Internet of Things (IoT) device capable of interacting with a mobile terminal, such as a smart car, computer, wireless router, or smart home device such as a smart door lock.

[0059] In this embodiment, the RFID tag is generally placed on or near the target device, such as the dashboard, storage compartment in front of the armrest box, or charging port cover of a smart car, so that drivers and passengers can scan and read it; the edge of the touchpad or the side of the laptop; or near routers or smart home devices.

[0060] In this embodiment of the application, the reading distance of the radio frequency tag can be set to 1-5 cm in order to take advantage of its short-range reading characteristics to accurately obtain the user's intent and avoid false triggering, but this embodiment of the application is not limited thereto.

[0061] In this embodiment, the RFID tag can be a passive tag or an active tag powered by the target device; it can also be another near-field communication reading module operating in card emulation mode on the target device, for example, the NFC module built into the vehicle's infotainment system can simulate bidirectional interaction between the tag and the extended device.

[0062] In this embodiment, the extended device is an accessory to the mobile terminal, such as a protective case for the mobile terminal, a smartwatch or other wearable device, or other portable accessories, such as a keychain.

[0063] In this embodiment of the application, the extended device can communicate with the mobile terminal via short-range wireless connection methods such as Bluetooth, WiFi, and Ultra-Wideband (UWB), or via USB or magnetic interface.

[0064] In this embodiment, the tag reading module is integrated within the expansion device and is a key component of the expansion device, possessing the ability to read RFID tag information. This module can employ existing NFC technology or other technologies suitable for reading RFID tags to acquire data from the RFID tag.

[0065] In this embodiment, the tag reading module can be activated in a periodic scanning normally-on mode, or it can be activated by the physical operating element of the extended device, or it can be activated in response to a command from the mobile terminal. For example, when the target device is a car, if the mobile terminal establishes a Bluetooth connection with the car, the mobile terminal can actively activate the tag reading module of the extended device so that it can subsequently read the RFID tag to trigger the application flow function.

[0066] In this embodiment of the application, the radio frequency tag is used to record the identification information of the target device, including but not limited to the device's unique code (such as MAC address, VIN code).

[0067] In this embodiment of the application, the reading result refers to all or part of the data obtained by the tag reading module from the radio frequency tag, including the identification information of the target device.

[0068] In this embodiment of the application, the first target message is used to transmit the reading result of the tag reading module for the radio frequency tag, so that the mobile terminal can obtain the information recorded by the radio frequency tag.

[0069] Step S220: Parse the first target message to obtain the identification information of the target device.

[0070] In this embodiment of the application, parsing the first target message to obtain the identification information of the target device includes: parsing the first target message through a protocol conversion module to obtain the identification information of the target device.

[0071] Step S230: Based on the identification information, send the second target message from the mobile terminal to the target device.

[0072] In this embodiment, the second target message can be used to transmit data to the target device, such as transmitting user identification information from the mobile terminal so that the target device (vehicle) can execute personalized commands from the user; transmitting files such as pictures, music, and videos from the mobile terminal; and transmitting information for application flow, etc. The second target message can also be used to send one or more control commands to the target device. Correspondingly, in addition to recording the identification information of the target device, the RFID tag can also be used to record the data type or control instructions to be transmitted.

[0073] In this embodiment, a tag reading module is provided on an extension device of the mobile terminal, and an RFID tag for recording its identification information is provided at the target device. The tag reading module on the extension device sends the reading result to the mobile terminal through a first target message. The mobile terminal obtains the identification information of the target device by parsing the tag reading result, and can then interact with the target device. Communication and interaction between the mobile terminal and the target device are achieved through the tag reading module on the extension device and the RFID tag at the target device, simplifying the interaction process between the mobile terminal and the target device. It also enables terminals without tag reading capabilities to support tag reading through the tag reading module integrated on the extension device. Simultaneously, it bypasses the dependency on calling the wallet app on the mobile terminal, avoiding business negotiations and licensing costs with terminal manufacturers.

[0074] based on Figure 2 In addition to the method described in the embodiments of this specification, some specific implementation schemes of the method are also provided, which will be described below.

[0075] Optionally, the RFID tag is also used to record connection information of the short-range wireless communication protocol of the target device;

[0076] Sending the second target message from the mobile terminal to the target device includes:

[0077] Determine whether the mobile terminal is communicatively connected to the target device;

[0078] If the mobile terminal is in communication connection with the target device, then the second target message from the mobile terminal is sent to the target device;

[0079] If the mobile terminal is not connected to the target device, a communication connection is established between the mobile terminal and the target device based on the connection information, and the second target message from the mobile terminal is sent to the target device.

[0080] In the embodiments of this application, the short-range wireless communication protocol may include Bluetooth, Wi-Fi Direct, ZigBee, etc., but the embodiments of this application are not limited thereto.

[0081] In this embodiment, the reading result can be used to establish a communication connection between the mobile terminal and the target device, thereby automatically completing device authentication and link configuration, eliminating redundant operations such as manual password input and device search, and improving cross-device interaction efficiency. That is, in addition to recording the identification information of the target device, the RFID tag is also used to record the connection information of the target device's short-range wireless communication protocol.

[0082] In this embodiment, the connection information is used to establish a communication connection between the mobile terminal and the target device based on a target communication protocol. The target communication protocol may include, but is not limited to, Bluetooth, WiFi, and ultra-wideband communication protocols.

[0083] In this application embodiment, the connection information may include the type of short-range wireless communication protocol and the data required to establish such a communication connection, such as Bluetooth pairing code / PIN, Wi-Fi SSID and WPA2-PSK password, UWB service UUID and channel parameters, but this application embodiment is not limited thereto.

[0084] In this embodiment of the application, establishing a communication connection between the mobile terminal and the target device based on the connection information may include: automatically initiating a connection request and completing authentication based on the connection information.

[0085] In this embodiment of the application, the second target message is used to transmit data to the target device, send control commands to the target device, etc.

[0086] In this embodiment, after receiving the first target message sent by the extended device, the mobile terminal obtains the identification information of the target device and the connection information of the target device's short-range wireless communication protocol by parsing the tag reading result. If the two are not currently connected, a communication connection is established based on the connection information, and the second target message from the mobile terminal is sent to the target device. If a communication connection has been established, the second target message is sent directly. Regardless of whether a communication connection has been established, the second target message can be sent to the target device quickly and reliably, thereby simplifying the interaction process between the mobile terminal and the target device and improving the user experience.

[0087] Optionally, the connection information is used to establish a communication connection between the mobile terminal and the target device based on a target communication protocol; the target communication protocol includes any one of Bluetooth communication protocol, WiFi communication protocol, and ultra-wideband communication protocol.

[0088] Optionally, sending the second target message from the mobile terminal to the target device includes:

[0089] Send a second target message to the target device; the second target message is used to instruct the target device to perform a user-preset automatic action.

[0090] In this embodiment of the application, the second target message is used to instruct the target device to perform an automatic action preset by the target user.

[0091] In this embodiment of the application, the target user can be a user of the mobile terminal.

[0092] In this embodiment of the application, the second target message may carry identification information for automatically executed actions; in some cases, the second target message may also carry user unique identification information and auxiliary data such as configuration parameters required for executing actions.

[0093] In this embodiment, the automatically executed actions can be predefined and stored by the user on the mobile terminal. When the target device is a vehicle, the automatically executed actions may include cabin configurations such as seat position and steering damping, and rearview mirror angle matching; environmental control operations such as temperature and humidity and air circulation adjustment; and intelligent interactive configurations such as ambient lighting and playlists. When the target device is a personal computer, the actions may cover operations such as automatically logging into a user account, synchronizing the desktop layout, and loading customized software configurations.

[0094] In this embodiment, the user places the extension device close to the RFID tag of the target device. The extension device reads the RFID tag and sends a first target message to the mobile terminal. After receiving the first target message from the extension device, the mobile terminal sends a second target message to the target device. Upon receiving the second target message, the target device executes a user-preset automatic action. Thus, through the close-range interaction between the extension device and the target device's RFID tag, the target device identifies the user of the mobile terminal and executes the user's automatic actions, greatly improving the convenience and intelligence of the device.

[0095] Optionally, sending the second target message from the mobile terminal to the target device includes:

[0096] A second target message carrying user identification information from the mobile terminal is sent to the target device; the target device is used to execute a user-preset automatic action based on the user identification information.

[0097] In this embodiment of the application, the target device may store identification information for automatically executed actions.

[0098] In practical applications, the target device may have multiple users, such as multiple drivers for a vehicle or multiple different users for a computer; different users may have different habits and configuration files.

[0099] In this embodiment, the user places the extension device close to the RFID tag of the target device. The extension device reads the RFID tag and sends a first target message to the mobile terminal. After receiving the first target message from the extension device, the mobile terminal sends a second target message to the target device. Upon receiving the second target message, the target device executes a user-preset automatic action based on the user identification information. Thus, through the close-range interaction between the extension device and the target device's RFID tag, the target device identifies the user of the mobile terminal and executes the user's automatic actions, greatly improving the convenience and intelligence of the device.

[0100] Furthermore, traditional smart cockpit memory systems typically rely on cameras to collect biometric data for identity verification, which not only faces the risk of user privacy leaks but also suffers from response delays due to their passive identification mechanism. On the other hand, methods that detect the driver via Bluetooth / Wi-Fi signals from mobile devices or radio frequency signals from car keys may capture multiple wireless signals simultaneously in multi-passenger scenarios, making it difficult to accurately determine the actual driver's identity.

[0101] In the embodiments of this application, when the solution is used in an intelligent cockpit memory system, by extending the close-range interaction events between the device and the target vehicle (target device)'s RFID tag, the target vehicle can identify the user of the mobile terminal and identify them as the driver during the driving trip. This avoids continuous monitoring of user behavior by the camera and achieves unique identity binding through the physical contact characteristics of the RFID tag, accurately completing user identification and personalized function calls while protecting privacy.

[0102] Optionally, the second target message carries application information of the target application at the mobile terminal; the application information is used to transfer the target application to the target device.

[0103] In this embodiment of the application, sending the second target message from the mobile terminal to the target device includes: sending application information of the target application from the mobile terminal to the target device; the application information is used to transfer the target application to the target device.

[0104] In the embodiments of this application, the target device may be a vehicle or an in-vehicle computing terminal, or it may be a terminal device such as a tablet computer, a laptop computer, or a desktop computer, or it may be a smart TV, a smartwatch, or a smart home device.

[0105] In this embodiment of the application, the target application may be an application pre-set by the user or a foreground application on the mobile terminal; the target application may specifically include navigation applications, music applications, video applications, communication applications, reading applications, shopping applications, etc., without specific limitations.

[0106] In this embodiment of the application, the application information of the target application may include the application's identifier, related application parameters, and other data.

[0107] In this embodiment, the target device can launch or switch to the corresponding target application based on application information, and restore the application state of the target application on the mobile terminal. For example, if the application information points to a music application, the music application on the target device will be launched and the playlist and playback status will be synchronized; if the application information points to a map application, the map application on the target device will be launched and the destination information or navigation status will be synchronized.

[0108] In this embodiment, the user brings the extended device close to the RFID tag of the target device. The extended device reads the RFID tag and sends a first target message to the mobile terminal. After receiving the first target message from the extended device, the mobile terminal sends the application information of the target application on the mobile terminal to the target device. The target device can then launch or switch to the corresponding target application based on the application information and restore the application state of the target application on the mobile terminal, thereby transferring the target application to the target device. This uses the close-range interaction event between the RFID tags of the extended device and the target device as a trigger signal to achieve seamless application transfer, ensuring end-to-end service continuity. Simultaneously, it simplifies the operation steps of multi-device collaboration into a single touch action, reducing user operation steps and improving interaction efficiency and user experience.

[0109] Furthermore, the above solution is implemented on terminals that do not have native tag reading capabilities, and completely bypasses the API call dependency of the wallet application pre-installed by mobile terminal manufacturers, avoiding business negotiation and authorization costs caused by system permission restrictions, and significantly expanding the applicability of the solution in third-party devices.

[0110] Optionally, the target device is a target vehicle.

[0111] Based on the same idea, this application also provides another method for short-range information transmission. Figure 3 This is a flowchart illustrating a short-range information transmission method provided in another embodiment of this application. Figure 3 The method is performed by an extension device that is communicatively connected to the mobile terminal, the extension device being equipped with a tag reading module.

[0112] like Figure 3 As shown, the method includes the following:

[0113] Step S310: Based on the tag reading module, obtain the reading result of the RFID tag at the target device; the RFID tag is used to record the identification information of the target device;

[0114] Step S320: Send a first target message to the mobile terminal; the first target message is used to transmit the reading result of the tag reading module for the radio frequency tag; the target device is used to parse the first target message to obtain the identification information of the target device, and send a second target message from the mobile terminal to the target device according to the identification information.

[0115] Optionally, the tag reading module is a near-field communication reading module; before obtaining the reading result of the RFID tag at the target device, it further includes:

[0116] In response to a user's target operation on a physical operating element at the extended device, the near-field communication reading module is switched to reader mode;

[0117] And / or, after receiving the activation command sent by the mobile terminal, the near-field communication reading module is switched to reader mode.

[0118] In the embodiments of this application, the target operation can be freely set according to the form of the physical operation element, without specific restrictions.

[0119] In this embodiment of the application, before the user inputs a target operation on the physical operating element, or before receiving an activation command sent by the mobile terminal, the tag reading module maintains a low-power sleep state and shuts down the radio frequency signal transmission unit to reduce energy consumption.

[0120] In this embodiment, the tag reading module is activated to read the RFID tag at the target device only after receiving a user's target operation on the physical operating element or after receiving an activation command from the mobile terminal. This design keeps the tag reading module in a low-power state most of the time, effectively extending the battery life of the extended device. By reducing unnecessary operating time of the tag reading module, not only is the accuracy of the reading operation improved and misreadings that may occur due to frequent readings avoided, but the device's energy consumption is also further reduced. In addition, this on-demand activation mechanism improves the device's security to a certain extent, reducing the risk of data leakage due to malicious attacks on the tag reading module. Because the tag reading module is only activated and reads data when triggered by a specific operation or command, unnecessary data exposure is avoided.

[0121] Optionally, in card emulation mode, the near-field communication reading module is used to provide preset tag data after being read;

[0122] After switching the near-field communication reading module to reader mode, the method further includes:

[0123] If the near-field communication reading module remains in reader mode for a preset activation time, then the near-field communication reading module will be switched to card emulation mode.

[0124] And / or, after sending the first target message to the mobile terminal, the near-field communication reading module is switched to card emulation mode.

[0125] In this embodiment of the application, the preset tag data is used to trigger specific operations, such as contactless interaction in scenarios of identity authentication, electronic payment, or device control.

[0126] In this embodiment of the application, in Card Emulation Mode, the near-field communication reading module of the extended device switches to Card Emulation Mode to simulate a passive tag that can be read by other NFC devices.

[0127] In this embodiment of the application, the near-field communication reading module can provide preset tag data to the target device after being read by the target device, so as to trigger the target device to execute corresponding instructions, such as opening the car door, opening the access control, or starting the payment process.

[0128] In this embodiment, the near-field communication reading module defaults to card emulation mode and automatically switches to card emulation mode after tag reading. Offline verification is achieved based on preset tag data, allowing the extended device to independently complete near-field interaction without the main device, ensuring emergency use needs and improving the reliability of the extended device. Furthermore, in card emulation mode, non-essential communication modules in the extended device can be turned off, significantly reducing standby power consumption and extending battery life.

[0129] For example, when a user's mobile phone is turned off, a smart car lock equipped with an NFC module can still receive virtual key data sent by an extension device through card emulation mode and directly unlock the vehicle; similarly, electronic door locks can read virtual key data simulated by an extension device to achieve offline identity verification and access control, avoiding the problem of being unable to open the door due to mobility failure.

[0132] like Figure 4 As shown, the mobile terminal includes one or more processors 410 and memory 420.

[0133] The processor 410 may be a central processing unit (CPU) or other form of processing unit with data processing capabilities and / or instruction execution capabilities, and may control other components in the mobile terminal to perform desired functions.
