[0024] To make the technical solution of this application clearer and easier to understand, the following describes how this method is applied in the above-mentioned application scenario. Figure 1 Taking AP device 104 as an example, this application describes an interface switching method provided in its embodiments. Figure 2 As shown in the figure, this figure is a flowchart illustrating an interface switching method provided in an embodiment of this application.

[0025] S201. Obtain the target level signal and WAN interface configuration information of the AP wireless access point device.

[0026] One possible approach is to detect the grounding status of the conductive structure in the optical module interface of an AP device to obtain a target level signal; and to acquire WAN interface configuration information based on a preset instruction.

[0027] Optionally, based on a preset detection period, the level signal and WAN interface configuration information are acquired; wherein the detection period is shorter than the port loop detection period.

[0028] Among them, AP (Access Point) wireless access point devices, or APs for short, are network devices that convert wired network signals into wireless signals, allowing wireless terminals such as mobile phones and computers to access the network. They are components for building wireless local area networks. The AP device needs to support optical and electrical WAN port switching to adapt to different wide area network access scenarios.

[0029] The target level signal refers to the electrical signal state (high level / low level) used to determine whether the optical module is in place. It is an important basis for detecting the presence of the optical module. When the optical module is inserted, its shell grounds the conductive structure of the AP optical module interface, and the detection device recognizes a low level. When the optical module is not inserted, the conductive structure is not grounded, and the detection device recognizes a high level.

[0030] The WAN (Wide Area Network Port) is the physical / logical interface through which an AP device connects to a wide area network. It is divided into two types: electrical WAN (which transmits electrical signals via a network cable, and the interface is mostly of type RJ45) and optical WAN (which transmits optical signals via optical fiber, and requires the use of an optical module). The type of the interface needs to be identified through its configuration information.

[0031] The conductive structure in the optical module interface is a metal or conductive component inside the optical module interface of the AP device used to cooperate with the optical module to realize grounding detection. It is the hardware basis for level signal detection. When the optical module is inserted, its shell contacts the conductive structure and grounds it, triggering a low-level signal. When not inserted, the structure remains ungrounded and outputs a high-level signal.

[0032] Preset commands refer to commands predefined in the AP device system for reading WAN port configuration information, such as the ethtool command, which can extract key configuration information such as the Supported ports field (distinguishing between electrical / optical interfaces) and bus address of the WAN port.

[0033] The preset detection period refers to the time interval set by the system for periodically acquiring level signals and WAN port configuration information, such as 100 milliseconds by default. Its purpose is to ensure the real-time detection of interface status.

[0034] The port loop detection cycle refers to the time interval used by network devices such as switches to detect whether there is a network loop (such as signal loop caused by incorrect network cable connection) in the port. The default cycle is 1-10 seconds, which is a reference for setting the detection cycle of AP devices.

[0035] For example, the dedicated physical slot / interface structure designed on the AP device to accommodate optical modules has a cavity, conductive contacts, and positioning components that match the shape of the optical module. From a hardware perspective, the optical module can be directly plugged into this interface. After insertion, not only can optical signals be transmitted through the interface, but its metal casing will also contact the preset conductive structure inside the interface and ground it, thereby triggering the AP device system to detect the target level signal. That is, this interface is the carrier for the physical connection, signal transmission, and presence detection between the optical module and the AP device, and it is also the hardware foundation for optical WAN port access to the wide area network.

[0036] When the optical module is inserted, its metal casing contacts the conductive structure, grounding the structure. The AP device system's detection device recognizes a low-level signal (this is the target level signal for the optical module being in place). When the optical module is not inserted, the conductive structure remains ungrounded, and the detection device recognizes a high-level signal (this is the target level signal for the optical module not being in place). The target level signal is obtained through this hardware detection action. Subsequently, the AP device system executes a preset ethtool command (such as ethtool eth0) to read the WAN interface configuration information, including "Supported" used to distinguish the interface type. The "ports" field (e.g., "TP" for electrical WAN ports, "Fiber" for optical WAN ports) and the WAN port bus address (which can be used for comparison and verification with a pre-stored address database) are used to obtain WAN interface configuration information. Simultaneously, to ensure real-time interface status detection and avoid conflicts with switch loop detection, the AP device system will periodically repeat the operations of "detecting the grounding status of conductive structures and obtaining level signals" and "calling preset instructions to obtain WAN interface configuration information" according to a preset detection cycle (default 100 milliseconds, which is less than the typical 1-10 second port loop detection cycle of switches). This captures real-time states such as optical module insertion / removal and WAN port type changes. The detection cycle can be dynamically adjusted through a configuration file to adapt to different switch parameters, ensuring timely interface switching decisions and network stability.

[0037] S202. Determine the optical module status based on the target level signal, and determine the interface type based on the WAN interface configuration information.

[0038] One possible approach is to determine that the optical module insertion state is in place when the target level signal is low, and to determine that the optical module insertion state is not in place when the target level signal is high.

[0039] The insertion status of the optical module can also be verified based on the storage information of the optical module.

[0040] Furthermore, preset fields are extracted from the WAN interface configuration information; if the value of the preset field is the first preset value, the interface type is determined to be an electrical WAN interface; if the value of the preset field is the second preset value, the interface type is determined to be an optical WAN interface.

[0041] The bus address of the WAN interface can also be obtained and compared with a pre-stored interface address database to verify the interface type.

[0042] The optical module status refers to the connection status between the optical module and the AP device, including two categories: in-place status (the optical module has been inserted into the optical module interface of the AP device) and out-of-place status (the optical module has not been inserted or has not been correctly inserted into the interface).

[0043] WAN interface configuration information is a set of parameters stored in the AP device system that describes the attributes of the WAN port, including interface type, bus address, speed, and other information, and is used to identify the specific type of WAN port.

[0044] The stored information of the optical module is its own working status data stored locally inside the optical module, such as whether the module is operating normally and whether the connection is stable. It can be read through the IIC (Inter-Integrated Circuit Interface) interface for secondary verification of the accuracy of the optical module's in-situ status.

[0045] Predefined fields are specific fields that are predefined in the WAN interface configuration information and are used to distinguish the interface type, such as the Supported ports field read by the ethtool command.

[0046] The first preset value and the second preset value correspond to specific values ​​of the preset fields; for example, the first preset value is "TP (Twisted Paired)" to identify the electrical WAN interface; the second preset value is "Fiber" to identify the optical WAN interface.

[0047] The bus address of the WAN interface is a unique address identifier for the WAN port on the hardware bus of the AP device. It is the hardware attribute information that distinguishes different WAN ports (optical WAN port, electrical WAN port).

[0048] The pre-stored interface address library is a set of standard bus addresses corresponding to optical WAN ports and electrical WAN ports that are pre-stored in the AP device system. It is used to compare with the actual obtained WAN port bus address to verify the interface type judgment result.

[0049] The optical module status includes in-position and out-of-position states.

[0050] Interface types include electrical WAN interfaces and optical WAN interfaces.

[0051] For example, when a low-level target signal is detected, the optical module is determined to be in place, meaning it has been inserted into the AP device's optical module interface. When a high-level target signal is detected, the optical module is determined to be out of place, meaning it has not been inserted or has not been correctly inserted into the interface. To ensure accurate judgment, the system also reads the optical module's stored information through the IIC interface to perform a secondary verification of the initially determined optical module insertion status. Subsequently, the system processes the WAN interface configuration information to determine the interface type. For example, it first extracts a preset field (Supported ports field) from the WAN interface configuration information. If the field value is the first preset value "TP", the interface type is determined to be an electrical WAN interface. If the field value is the second preset value "Fiber", the interface type is determined to be an optical WAN interface. To further improve the reliability of identification, the system also obtains the current WAN interface's bus address and compares it with the pre-stored interface address database (including the standard bus address of the optical WAN port and the standard bus address of the electrical WAN port) to verify whether the interface type determined based on the preset field is accurate. Finally, the system completes the determination of the optical module status and the reliable identification of the WAN interface type.

[0052] S203. Based on the optical module insertion status and interface type, determine the interface switching action of the AP device.

[0053] One possible implementation is that, when the optical module is inserted in place and the interface type is an optical WAN interface, the AP device's interface switching action is no switching; when the optical module is inserted in place and the interface type is an electrical WAN interface, the AP device's interface switching action is switching; when the optical module is not inserted in place and the interface type is an optical WAN interface, the AP device's interface switching action is switching; and when the optical module is not inserted in place and the interface type is an electrical WAN interface, the AP device's interface switching action is no switching.

[0054] Write the identifier of the target device tree file into the startup parameters of the AP device; wherein, the target device tree file includes a first device tree file for configuring the optical WAN interface or a second device tree file for configuring the electrical WAN interface; control the AP device to restart, so as to load the corresponding device tree configuration based on the identifier in the startup parameters, thereby completing the WAN interface switching.

[0055] The target device tree file is a file based on the Linux kernel architecture used to define the hardware configuration of AP devices. Specifically, it includes a dedicated device tree file adapted to optical WAN interfaces or a dedicated device tree file adapted to electrical WAN interfaces. It is the core carrier for implementing interface hardware parameter configuration and driver loading.

[0056] The first device tree file is a subclass of the target device tree file, specifically used to configure the hardware parameters of the optical WAN interface, such as the optical port driver model, optical signal transmission rate, and optical interface bus address. After loading, the AP device can enable the optical WAN port function.

[0057] The second device tree file is a subclass of the target device tree file, specifically used to configure the hardware parameters of the electrical WAN interface, such as the electrical port RJ45 driver, electrical signal transmission rate, and electrical interface bus address. After loading, the AP device can enable the electrical WAN port function.

[0058] The startup parameters of an AP device are configuration parameters stored in the AP device's bootenv, i.e., startup environment variables, which guide the device startup process. The core parameter is config_name, whose value is the identifier of the target device tree file, which determines the hardware configuration file loaded when the device starts.

[0059] For example, firstly, based on the determined optical module insertion status and WAN interface type, a preset logic determines whether to perform an interface switching action. When the optical module is in place and the current interface type is an optical WAN interface, it is determined that the user's access intention is met, and the interface switching action is not performed. When the optical module is in place but the current interface is an electrical WAN interface, it is determined that the optical module access requirement needs to be adapted, and the switching action is performed. When the optical module is not in place but the current interface is an optical WAN interface, it is determined that the optical port has no actual access conditions, and the switching action is performed. When the optical module is not in place and the current interface is an electrical WAN interface, it is determined that the access requirement without the module is met, and the switching action is not performed. If it is determined that a switching action needs to be performed, the AP device system will further determine the target device tree file. If switching to the optical WAN port is required, the first device tree file is selected; if switching to the electrical WAN port is required, the second device tree file is selected. The identifier of the target device tree file is written into the bootenv startup parameter, i.e., the config_name parameter, of the AP device. Subsequently, the AP device system controls the AP device to execute an automatic restart command. After the device enters the boot process, it reads the target device tree file identifier stored in the bootenv boot parameters during the uboot stage, loads the corresponding device tree configuration from the file library of the pre-compiled Linux kernel image, and after the kernel completes initialization, it enables the corresponding WAN interface driver and hardware parameters according to the loaded device tree file, and finally completes the WAN interface switching.

[0060] It should be noted that the process involves acquiring the target level signal and WAN interface configuration information of the AP wireless access point device; determining the optical module status based on the target level signal and the interface type based on the WAN interface configuration information; and determining the AP device's interface switching action based on the optical module insertion status and interface type. This establishes a two-dimensional decision-making basis combining hardware signals and configuration information, providing a unified technical framework for subsequent accurate detection and automatic switching. It avoids misjudgments in switching due to a single detection dimension and fragmented decision-making logic, thus solving the pain point of lacking standards for detection and decision-making.

[0061] By determining the switching actions of the optical module's insertion status and interface type under different combinations, the resource waste of using inefficient electrical ports when the optical module is in place is avoided, and the service interruption caused by the optical port running idle after the optical module is removed is prevented. This ensures that the switching decision fully matches the user's access intention and solves the problem of switching triggering without a basis.

[0062] By determining whether the optical module is inserted in a low or high level based on the target signal level, the system avoids misidentification caused by signal interference through a strong correlation between the grounding status and the signal level at the hardware level. At the same time, combined with the verification of the optical module's stored information, a dual verification of hardware signals and module self-test is formed, which greatly reduces the false judgment rate of optical module detection, solves the problem of unreliable optical module status identification, and provides accurate hardware status basis for switching decisions.

[0063] By clearly extracting preset fields and matching field values, and by calling the system's underlying configuration information, a standardized interface type identification method is established to avoid misjudgments caused by manual identification or non-standard instructions. Combined with the verification logic of bus address comparison, the accuracy of interface type identification is further improved, solving the problem of the lack of a reliable method for WAN port type identification.

[0064] By clearly defining the specific implementation paths for obtaining level signals by detecting the grounding status of conductive structures and obtaining WAN interface configuration information based on preset instructions (the former can be achieved through the existing optical module interface conductive structure of the AP device without additional hardware; the latter reads the configuration through the general "ethtool" instruction without the need for customized tools), the solution utilizes the original hardware resources of the equipment to reduce costs and reduces technical differences between manufacturers through standardized testing methods. This solves the problems of inconsistent testing methods and difficulty in implementation, making it easier for the solution to be promoted on a large scale.

[0065] By explicitly designing the detection cycle to be shorter than the port loop detection cycle, the AP device ensures that the entire process of status detection, switching decision, and interface switching is completed before the switch determines a loop, avoiding port shutdown caused by switching delays. At the same time, it supports dynamic adjustment of the detection cycle, which can adapt to the loop detection parameters of different brands of switches, solving the problems of fixed detection cycles and poor compatibility, ensuring network stability in different deployment scenarios, and avoiding service interruptions.

[0066] By explicitly writing the target device tree identifier into the startup parameters, automatically restarting, and loading the corresponding configuration, a fully automated switching process is implemented. No manual intervention is required for DTS file selection and parameter configuration. The system can automatically match the first / second device tree file based on the switching decision, pass configuration instructions through startup parameters, and automatically load the corresponding interface configuration after restarting. The entire process requires no manual operation, and the time for restarting and loading the device tree is much shorter than the time spent on manual configuration, which greatly reduces business interruption time and solves the problems of cumbersome switching and long business interruptions.

[0067] The aforementioned interface switching method, by acquiring the target voltage level signal and WAN interface configuration information of the AP wireless access point device, provides a data foundation for subsequent determination of the current interface type. Furthermore, based on the target voltage level signal, it determines whether the optical module is in place or not, and based on the WAN interface configuration information, it determines whether the interface type is an electrical WAN interface or an optical WAN interface, accurately grasping the current interface status of the AP device. Consequently, based on the optical module insertion status and interface type, the interface switching action of the AP device can be determined. This solution, by introducing a target voltage level signal, provides a basis for accurately determining the optical module status; furthermore, by combining it with WAN interface configuration information, it achieves accurate determination of the current interface connection status, ultimately realizing automatic interface switching.
