[0002] Existing in-vehicle 4G networks typically rely on a single operator, leading to frequent connection interruptions in areas with poor signal coverage or network congestion. This severely impacts the stability of in-vehicle applications such as remote control, real-time data transmission, and multimedia resource sharing. With the rapid development of intelligent connected vehicles, in-vehicle terminals need to maintain continuous and reliable data interaction with cloud service platforms, placing higher demands on the stability and flexibility of network connections.

[0003] However, traditional solutions often require hardware replacement or system reconfiguration when faced with changes in operator services (such as switching between China Unicom, China Mobile, and China Telecom) or different service configurations within the same operator (such as changes between public and private APNs). This process is complex and time-consuming, increasing the operating costs and implementation difficulties for automakers and affecting the user's connected experience. It is difficult to meet the needs of intelligent connected vehicles for highly reliable and multi-scenario network connectivity, and this issue urgently needs to be addressed. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0055] With the development and popularization of in-vehicle intelligent terminals, in-vehicle terminals connect to cloud service platforms. To address the needs of in-vehicle 4G wireless network stability or changes in network operators and related APN configurations, including public and private APNs, and to ensure network stability for data transmission and interaction between the vehicle and the cloud, or to address changes in operator services (China Unicom, China Mobile, and China Telecom) or different service configurations of the same operator, this application proposes a compatibility design method based on multiple public and private APNs of multiple operators in in-vehicle 4G networks. This method aims to improve the reliability and flexibility of network connections for in-vehicle devices, adopts a software compatibility approach to achieve configuration changes for different operators or different APNs, eliminates the need for hardware replacement processes and cycles, reduces the complexity and cost for automakers to replace equipment, enhances in-vehicle network communication, improves user experience, supports seamless switching of multiple operator services, and is applicable to scenarios such as intelligent connected vehicles, remote monitoring, and in-vehicle multimedia sharing.

[0056] The following description, with reference to the accompanying drawings, describes a method, apparatus, and device for adaptive configuration of multiple APNs based on multiple operators, according to embodiments of this application.

[0057] Specifically, Figure 1 This is a flowchart illustrating a multi-operator-based multi-path APN adaptive configuration method provided in an embodiment of this application.

[0058] like Figure 1 As shown, this multi-carrier-based multi-path APN adaptive configuration method includes the following steps:

[0059] In step S101, in response to the power-on command of the current vehicle terminal device, the SIM card information in the communication module is read, and the operator type of the current SIM card is identified according to the SIM card information.

[0060] In step S102, the candidate APN configuration set corresponding to the operator type is called from the preset configuration strategy library, and the current APN configuration information in the communication module is read. The service scenario type corresponding to the current SIM card is identified according to the current APN configuration information. Based on the service scenario type corresponding to the current SIM card, the corresponding target APN configuration parameters are matched from the candidate APN configuration set.

[0061] In step S103, the target APN configuration parameters are written into the communication module, and a dial-up connection request is initiated based on the target APN configuration parameters to establish a network connection.

[0062] Furthermore, in some embodiments, identifying the operator type of the current SIM card based on the SIM card information includes: parsing the SIM card information and extracting the operator identification code; comparing the operator identification code with a preset operator identification database, and determining the operator type of the current SIM card based on the comparison result; wherein the operator type of the current SIM card is one of China Mobile, China Unicom, or China Telecom.

[0063] Furthermore, in some embodiments, identifying the service scenario type corresponding to the current SIM card based on the current APN configuration information includes: determining whether the current APN configuration information is empty, or whether the current APN configuration information contains a predefined scenario identifier; if the current APN configuration information contains a first scenario identifier, then the service scenario type corresponding to the current SIM card is determined to be a first service scenario, and the first service scenario corresponds to a first type of SIM card under the operator type to which the current SIM card belongs; if the current APN configuration information is empty, or the current APN configuration information contains a second scenario identifier, then the service scenario type corresponding to the current SIM card is determined to be a second service scenario, and the second service scenario corresponds to a second type of SIM card under the operator type to which the current SIM card belongs.

[0064] Furthermore, in some embodiments, the target APN configuration parameters include a public network APN parameter group and a private network APN parameter group. Initiating a dial-up connection request based on the target APN configuration parameters to establish a network connection includes: configuring a first data channel of the communication module using the public network APN parameter group and initiating a first dial-up request to the public Internet to establish a data link to the Internet; configuring a second data channel of the communication module using the private network APN parameter group and initiating a second dial-up request to the target private network to establish an intranet data link to the vehicle management cloud platform.

[0065] Furthermore, in some embodiments, after initiating a dial-up connection request based on the target APN configuration parameters, the method further includes: monitoring the current dial-up connection status; if the current dial-up connection status is a dial-up connection failure, then selecting backup APN configuration parameters from the candidate APN configuration set and re-initiating the dial-up connection request; if the current dial-up connection status is a dial-up connection success, then recording the currently used target APN configuration parameters and maintaining the network connection.

[0066] To help those skilled in the art to understand more clearly and intuitively the multi-operator, multi-APN compatibility method based on vehicle-mounted 4G network of this application, a detailed explanation is provided below with specific examples.

[0067] The communication module can be a 4G wireless communication module integrated inside the vehicle-mounted intelligent terminal (TBOX) to enable data transmission between the vehicle and the external network.

[0068] As one embodiment of this application, such as Figure 2 As shown, when changing to a different service plan within the same operator results in a change of the physical SIM card, the software compatibility method of this application is as follows:

[0069] (1) Software judgment logic: After the device is powered on, it automatically identifies the APN stored in the 4G module and thus determines whether it is the APN configuration of SIM card 1 or SIM card 2; this facilitates the identification of the SIM card hardware during OTA upgrade and thus performs the correct APN matching.

[0070] (2) When the APN of the 4G module is empty (not written) or SIM card 2 is detected, the device is determined to be the hardware of SIM card 2 and the APN of SIM card 2 is adapted; when the APN in the module is detected to be the APN of SIM card 1, the device is determined to be the hardware of SIM card 1 and the APN of SIM card 1 is adapted.

[0071] (3) The SIM’s APN is identified by adaptive software, and the matching APN is then configured with parameters to complete the dial-up network connection.

[0072] As one embodiment of this application, such as Figure 3 As shown, when different operator services are used in the same project, the software compatibility method of this application is as follows:

[0073] (1) After the device is powered on, the software automatically identifies the SIM card operator information of the 4G module. If the identified operator is China Mobile, the software automatically configures it with Quectel's public network APN and private network APN, and performs normal dialing and networking to provide network services to users and perform cloud business interaction.

[0074] (2) If the software automatically identifies the SIM card operator as China Unicom, the software will automatically configure the public network APN and private network APN of the Unicom operator, make normal dial-up network connection, provide network services to users, and conduct cloud business interaction.

[0075] (3) If the software automatically identifies the SIM card operator as China Telecom, the software will automatically configure the public network APN and private network APN of the telecom operator, make normal dial-up connections, provide network services to users, and conduct cloud business interactions.

[0076] Automatic identification based on the first power-on of different operators eliminates the need for updating different software versions, thus allowing car manufacturers or users to flexibly choose operator services and save on the cost and time of switching.

[0077] Therefore, this application, through an innovative multi-APN management strategy, achieves adaptive compatibility and intelligent switching across multiple operator networks, fundamentally eliminating dependence on a single operator. It can adaptively adapt to changes in operators or network service packages, effectively avoiding the impact of network interruptions during the change process and improving network service reliability. Simultaneously, this solution optimizes network resource utilization through an intelligent switching mechanism, not only improving data transmission efficiency but also better supporting diverse application scenarios such as in-vehicle multimedia sharing. Thus, it provides intelligent connected vehicles with an efficient, flexible, and stable network connectivity solution, powerfully promoting technological advancements and enhancing user experience in in-vehicle communication systems.

[0078] According to the multi-operator multi-APN adaptive configuration method proposed in this application, in response to the power-on command of the current vehicle terminal device, the SIM card information in the communication module is read and the operator type of the current SIM card is identified; the candidate APN configuration set corresponding to the operator type is called, and the current APN configuration information in the communication module is read to identify the service scenario type corresponding to the current SIM card; the corresponding target APN configuration parameters are matched from the candidate APN configuration set; the target APN configuration parameters are written into the communication module, and a dialing connection request is initiated based on the target APN configuration parameters to establish a network connection. This solves the problems of poor network stability, high switching costs, and inflexible adaptation to multi-operator needs caused by the reliance on a single operator and fixed APN configuration in existing vehicle 4G communication systems. It achieves automatic compatibility and adaptation of multiple operators and multiple APNs, thereby improving the reliability and flexibility of network connections and reducing the operating costs and implementation complexity for vehicle manufacturers.

[0079] Next, referring to the accompanying drawings, a multi-operator-based multi-APN adaptive configuration device based on an embodiment of this application is described.

[0080] Figure 4This is a block diagram of a multi-operator, multi-path APN adaptive configuration device according to an embodiment of this application.

[0082] The identification module 100 is used to respond to the power-on command of the current vehicle terminal device, read the SIM card information in the communication module, and identify the operator type of the current SIM card based on the SIM card information; the processing module 200 is used to call the candidate APN configuration set corresponding to the operator type from the preset configuration policy library, read the current APN configuration information in the communication module, identify the service scenario type corresponding to the current SIM card based on the current APN configuration information, and match the corresponding target APN configuration parameters from the candidate APN configuration set based on the service scenario type corresponding to the current SIM card; the configuration module 300 is used to write the target APN configuration parameters into the communication module and initiate a dial connection request based on the target APN configuration parameters to establish a network connection.

[0083] Furthermore, in some embodiments, the identification module 100 is used to: parse the SIM card information and extract the operator identification code; compare the operator identification code with a preset operator identification database, and determine the operator type of the current SIM card based on the comparison result; wherein the operator type of the current SIM card is one of China Mobile, China Unicom or China Telecom.

[0084] Further, in some embodiments, the processing module 200 is configured to: determine whether the current APN configuration information is empty, or whether the current APN configuration information contains a predefined scenario identifier; if the current APN configuration information contains a first scenario identifier, then determine that the service scenario type corresponding to the current SIM card is a first service scenario, and the first service scenario corresponds to a first type of SIM card under the operator type to which the current SIM card belongs; if the current APN configuration information is empty, or the current APN configuration information contains a second scenario identifier, then determine that the service scenario type corresponding to the current SIM card is a second service scenario, and the second service scenario corresponds to a second type of SIM card under the operator type to which the current SIM card belongs.

[0085] Furthermore, in some embodiments, the target APN configuration parameters include a public network APN parameter group and a private network APN parameter group. The configuration module 300 is used to: configure the first data channel of the communication module using the public network APN parameter group and initiate a first dial-up request to the public Internet to establish a data link to the Internet; configure the second data channel of the communication module using the private network APN parameter group and initiate a second dial-up request to the target private network to establish an intranet data link to the vehicle management cloud platform.

[0086] Furthermore, in some embodiments, after initiating a dial-up connection request based on the target APN configuration parameters, the configuration module 300 is also used to: monitor the current dial-up connection status; if the current dial-up connection status is a dial-up connection failure, select backup APN configuration parameters from the candidate APN configuration set and re-initiate the dial-up connection request; if the current dial-up connection status is a dial-up connection success, record the target APN configuration parameters currently used and maintain the network connection.

[0087] It should be noted that the foregoing explanation of the multi-carrier-based multi-path APN adaptive configuration method embodiment also applies to the multi-carrier-based multi-path APN adaptive configuration device of this embodiment, and will not be repeated here.

[0088] According to the multi-carrier multi-APN adaptive configuration device proposed in this application embodiment, in response to the power-on command of the current vehicle terminal device, it reads the SIM card information in the communication module and identifies the carrier type of the current SIM card; it calls the candidate APN configuration set corresponding to the carrier type, reads the current APN configuration information in the communication module, identifies the service scenario type corresponding to the current SIM card, and matches the corresponding target APN configuration parameters from the candidate APN configuration set; it writes the target APN configuration parameters into the communication module and initiates a dialing connection request based on the target APN configuration parameters to establish a network connection. This solves the problems of poor network stability, high switching costs, and inflexible adaptation to multi-carrier requirements caused by the reliance on a single carrier and fixed APN configuration in existing vehicle 4G communication systems. It achieves automatic compatibility and adaptation of multiple carriers and multiple APNs, thereby improving the reliability and flexibility of network connections and reducing the operating costs and implementation complexity for car manufacturers.
