Therefore, it is understood that these terms can be used interchangeably where appropriate, so that the described embodiments can be implemented in a different order unless otherwise specified in the diagram or description. In addition, the terms "is" and "has" and any variations thereof in this application are intended to cover all possible constituent elements on a non-exclusive basis. For example, a process, method, system, product or device comprising a number of steps or units is not necessarily limited to the steps or units that are explicitly listed, but may also include other steps or units that are not explicitly listed, or steps or units that are inherent to the process, method, product or device.
[0022] In this application, a "module" or "unit" refers to a computer program or a part of a computer program that has a specific function and works in conjunction with other related parts to achieve a predetermined goal. These modules or units can be implemented by software, hardware (such as processing circuits or memories), or a combination of the two.

[0023] The technical solutions in the present application will be described in detail below in conjunction with the drawings in the embodiments. It should be noted that the described embodiments are only a part of the present application, not all embodiments. In the following description, the "some embodiments" mentioned are only subsets of all possible embodiments, which may be the same or different subsets, and different embodiments may be combined with each other without conflict.
[0024] See also Figure 1 , Figure 1 1 is a flow chart of a vehicle computer image interface display method provided by an embodiment of the present application. The method may specifically include the following steps 101 to 104:
[0025] Step 101, obtaining public land mobile network information of a target network;
[0026] Specifically, the target network refers to the wireless communication network that the vehicle is currently connected to, that is, the mobile communication network where the vehicle is located; specifically, the target network can be a network provided by a specific operator that the vehicle is connected to during driving. This network may be a network selected by the vehicle within the network coverage of the local operator, or a suitable network that the vehicle automatically switches to in the case of cross-border roaming. Public Land Mobile Network (PLMN) information is binary data used to identify and describe a public mobile communication network connected to the ground.
[0027] Exemplarily, when the target network is China Mobile, the public land mobile network information is “1011011011010000”.
[0028] Through the implementation of step 101, basic data can be provided for subsequent operator information processing, ensuring that the vehicle system can accurately identify the current network environment.
[0029] Step 102, converting the public land mobile network information into binary format to obtain the operator information code;
[0030] Specifically, the goal of the base conversion is to convert the public land mobile network information (expressed in binary) into a decimal encoding format, and the operator information encoding is the result of base conversion of the public land mobile network information.
[0031] For example, the public land mobile network information is "1011011011010000", and the operator information code is "46000".
[0032] By implementing step 102, the original data is converted into a more concise coding form, which improves the processing efficiency and accuracy of the data, avoids the errors or processing difficulties that may be caused by directly processing complex original data, and ensures that subsequent steps can be carried out more smoothly.
[0033] Step 103, based on the operator information code, perform a mapping search in the global operator code library to obtain the operator information;
[0034] Specifically, the Global Operator Code Library is a database containing information about mobile operators in various countries and regions around the world. This database stores the unique identifier of each operator, as well as other related information, such as the operator's location, name, network type, service area, etc. Mapping search refers to searching the Global Operator Code Library based on the provided operator information code to find the corresponding operator information. Operator information refers to detailed information about the operator obtained through mapping search.
[0035] By implementing step 103, it can be ensured that the vehicle system can accurately identify and display the operator to which the vehicle is currently connected, and can efficiently and accurately complete the identification of operator information, especially when traveling across borders or roaming.
[0036] Step 104, displaying the operator information through the vehicle computer image interface;
[0037] Specifically, the vehicle computer image interface is a component of the graphical user interface in the vehicle system, responsible for displaying a variety of information, including vehicle status, navigation, entertainment, communication, network connection, etc.; the vehicle computer image interface can be a central control display screen, instrument panel display or head-up display (HUD), etc.
[0038] For example, assuming that the operator information is obtained through step 103 and mapped as "Current Network: China Mobile"; in step 104, a message such as "Current Network: China Mobile" will be displayed on the central touch screen or display screen and presented to the user in the form of text or icon. If the vehicle enters the network coverage area of another operator, the vehicle image interface will be dynamically updated to reflect the new operator information.
[0039] In this way, the vehicle system provides a real-time and intuitive display of the network status, allowing the driver or passenger to clearly see the currently connected operator and network status, helping users to understand the vehicle's network connection status in a timely manner.
[0040] Through the implementation of step 104, the user (driver or passenger) can see in real time the operator to which the vehicle is currently connected, which greatly improves the user experience. Especially in the case of cross-border roaming or frequent switching of operators, the user can clearly understand the current network status, which can help the user make decisions quickly, such as determining whether it is necessary to manually switch networks or deal with other network-related issues.
[0041] In summary, the embodiments of the present application automatically obtain and display the information of the operator to which the vehicle is currently connected, so that the user can intuitively understand the network status. Especially in a cross-border roaming environment, the vehicle's operator may switch frequently. This display method avoids user confusion and allows the driver to easily identify the currently connected operator; and through base conversion and mapping search of the global operator code library, the identification and display of the network status are automatically completed, so that the vehicle can display the correct operator information in real time regardless of the country or region, thereby simplifying the operation process and improving the efficiency and accuracy of information processing. In summary, the vehicle-machine image interface display method provided in the embodiments of the present application simplifies the operation process by automatically obtaining and displaying the current operator information, helping users to identify and understand the network status in real time and accurately in a cross-border roaming environment.
[0042] In some embodiments, the aforementioned operator information may include the operator location and the operator name; the aforementioned step 103 may include: splitting the operator information code to obtain the mobile country code and the mobile network code; based on the mobile country code and the mobile network code, performing a mapping search in the global operator code library to obtain the operator location and the operator name.
[0043] Specifically, the operator's location refers to the geographical area or country served by the operator, which represents the geographical affiliation of the operator, usually referring to the country or region where the operator operates. The operator name refers to the name of the provider of the mobile communication network, usually a brand name used commercially; for example, China Mobile, China Unicom, Vodafone, T-Mobile, etc. The Mobile Country Code (MCC) is a three-digit code used to identify a specific country or region; each country or region has a unique MCC number, which helps distinguish mobile communication networks in different countries around the world; for example, China's MCC is 460 and the United States' MCC is 310. The Mobile Network Code (MNC) is a 2-digit or 3-digit code used to identify a mobile network operator in a specific country; in a country, there may be multiple operators, and each operator will have a different MNC; for example, China Mobile's MNC is 00 and China Unicom's MNC is 01.
[0044] Through the implementation of the above embodiment, the operator information code is split, and a mapping search is performed on the global operator code library based on the mobile country code and the mobile network code, ensuring more accurate operator identification and display, so that users can more clearly know that the network they are currently connected to is not just a certain operator, but specific to the geographical location and name of the operator.
[0045] In some embodiments, the aforementioned vehicle-mounted image interface display method may further include: scanning to obtain available public land mobile network frequency bands; selecting a target public land mobile network frequency band from the public land mobile network frequency bands according to the network type supported by the user identity module card; and connecting to the target network according to the target public land mobile network frequency band.
[0046] Specifically, the available public land mobile network frequency band refers to the radio frequency band that is open to the terminal equipment by various operators in the target area. By scanning these frequency bands, it is possible to determine which frequency bands are available to the vehicle, so as to select the best frequency band for network connection. For example, in Europe, common frequency bands include 800MHz, 900MHz, 1800MHz, 2100MHz, etc. Different frequency bands correspond to different operators and network types. The Subscriber Identity Module Card (SIM card) is a smart card that contains key information for identifying users and can be used in mobile devices such as mobile phones or vehicle terminals. The supported network type refers to the different types of mobile communication networks that the SIM card can connect to. According to different SIM cards and operators, the SIM card can support different network standards, such as 2G (GSM), 3G (UMTS / WCDMA), 4G (LTE) and 5G (NR). If the SIM card supports LTE (i.e., 4G network), the vehicle terminal will give priority to the frequency band that supports LTE. If the SIM card only supports 2G network, the terminal can only connect to the 2G network frequency band. The target public land mobile network frequency band refers to the frequency band that the vehicle terminal finally selects for establishing a network connection after scanning and combining the network types supported by the SIM card. Each operator usually provides multiple frequency bands, and the vehicle terminal will select the most suitable frequency band based on the supported type of the SIM card to ensure the stability of the network connection and the data transmission rate. For example, if the vehicle SIM card supports LTE (4G) and in the current area, the operator provides LTE bands of 1800MHz and 2100MHz, one of the frequency bands will be selected for connection. If the vehicle SIM card only supports 2G, the 2G band, such as the 900MHz (GSM) band, will be selected.
[0047] Through the implementation of the above embodiments, the efficiency and stability of the network connection are guaranteed, especially when traveling across borders, the vehicle can automatically switch to the appropriate frequency band to ensure that the vehicle maintains a good network connection between different countries / regions.
[0048] In some embodiments, the aforementioned connecting to the target network according to the target public land mobile network frequency band may include: camping on the target base station cell according to the target public land mobile network frequency band; and connecting to the target network according to the target base station cell.
[0049] Specifically, the target base station cell refers to the base station coverage area in a specific mobile communication network, with which the vehicle terminal (such as T-Box) establishes a connection through wireless communication signals; each base station is responsible for a geographical area, which is called a "cell"; the vehicle terminal selects the base station cell that is closest to it and has a stronger signal strength to establish a connection based on its location. Different cells may use different radio frequency bands and technologies (such as LTE, 3G, etc.).
[0050] Exemplarily, after selecting the target frequency band, the vehicle terminal will scan the available base station cells on the frequency band and select the most suitable cell for connection based on the signal strength; after successfully residing in the cell, the vehicle terminal connects to the network through the cell to complete data transmission and establishment of a network session.
[0051] Through the implementation of the above embodiment, connection to the target base station cell is performed according to the selected target public land mobile network frequency band, which helps to ensure efficient and stable network connection.
[0052] In some embodiments, the aforementioned camping on the target base station cell according to the target public land mobile network frequency band may include: acquiring an alternative base station cell according to the target public land mobile network frequency band; when there is preset broadcast control channel carrier information, selecting a target base station cell from the alternative base station cells according to the preset broadcast control channel carrier information, and camping on the target base station cell; when there is no preset broadcast control channel carrier information, selecting a base station cell with a signal strength greater than a preset strength from the alternative base station cells as the target base station cell, and camping on the target base station cell.
[0053] Specifically, the candidate base station cell refers to multiple base station cells available to the vehicle terminal within a specific frequency band. These cells may be within the coverage range of the vehicle, waiting to be selected as the target base station for final connection. The preset broadcast control channel carrier information refers to the signal sent by the base station via broadcast, which is used to help the terminal identify and select the specific parameters of the target base station. This information usually includes the base station identifier, signal quality, frequency and other data, which is used to guide the terminal to select the most suitable base station cell. The preset strength is a set signal strength threshold used to determine whether the base station signal is strong enough to ensure a reliable network connection. If the signal strength of the selected base station cell is lower than the preset strength, the terminal will not select the cell for connection.
[0054] Exemplarily, the target public land mobile network frequency band can be scanned first, and all candidate base station cells can be obtained; if the preset broadcast control channel carrier information is originally stored, the target base station cell with the best signal quality will be selected from the candidate base station cells for residence based on the information; if the preset broadcast control channel carrier information is not stored, the base station cell with a signal strength greater than the preset strength will be selected for connection, thereby ensuring a stable network connection.
[0055] Through the implementation of the above embodiments, the adaptability of the vehicle system in different environments is enhanced, and the network stability during cross-border driving or multi-region driving is improved.
[0056] In some embodiments, the aforementioned connecting to the target network according to the target base station cell may include: acquiring a master information block and a system information block of the target base station cell; and attaching and connecting to the target network according to the master information block and the system information block.
[0057] Specifically, the Master Information Block (MIB) is one of the control signals broadcast by the base station, which contains basic parameters related to network connection and communication, such as the broadcast information of the cell, system configuration, transmission mode, etc. It is the key information required for the initial access of the terminal to the network. The System Information Block (SIB) is another type of control information sent by the base station, which contains more detailed system parameters, such as frequency planning, transmission time slots, scheduling information, supported services, etc. This information can be read to understand how to operate correctly in the network and select appropriate resources.
[0058] Exemplarily, the vehicle terminal first obtains the master information block and system information block of the target base station cell, which contains the configuration and communication parameters of the target network. Then, based on the obtained master information block and system information block, the vehicle terminal parses all the information required to connect to the target network. Finally, based on this information, the vehicle terminal initiates an attachment request to the target base station, completes the connection with the target network, and starts data transmission.
[0059] Through the implementation of the above embodiments, it is ensured that the vehicle system can maintain a stable network connection in the case of rapid switching, thereby improving the continuity and reliability of vehicle networking services.
