[0082] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0083] The communication method of a 4G module provided by the embodiments of the present application can be applied in an application environment as shown in Figure 1 . Specifically, the communication method of a 4G module is applied in a communication system of a 4G module, and the communication system of a 4G module includes a host device and a slave device as shown in Figure 1 . The host device and the slave device communicate through a USB (Universal Serial Bus, commonly referred to as USB). The slave device includes but is not limited to a 4G module and a human-computer interaction device. Exemplarily, the human-computer interaction device includes but is not limited to a mouse and a keyboard. Exemplarily, the host device is provided with a plurality of USB interfaces, and the host device is connected with the slave device through the plurality of USB interfaces.

[0084] In an embodiment, as shown in Figure 2As shown, a communication method of a 4G module is provided, and the method is applied to Figure 1 a host device in the 4G module

[0085] S201: Obtain a device connection request, and the device connection request includes a data descriptor.

[0086] S202: Determine a device type of a current device based on the data descriptor.

[0087] S203: If the device type is a human-computer interaction device, initialize a communication mode of the current device, and use a first processing logic to perform data communication of the 4G module.

[0088] S204: If the device type is the 4G module, use a second processing logic to perform data communication of the 4G module.

[0089] The device connection request is a request of a slave device to connect to the host device. The data descriptor is data used to describe the device type of the slave device. The device type includes but is not limited to the 4G module and the human-computer interaction device.

[0090] As an example, in step S201, the host device obtains the device connection request, and performs preliminary analysis on the slave device according to the data descriptor in the device connection request, to determine whether the slave device needs to be connected, so as to facilitate the analysis and connection in the subsequent steps. Optionally, the request length of the device connection request can be set by the user, and the data descriptor in the device connection request can be used to determine the device type in the subsequent steps, which is not limited herein.

[0091] As an example, in step S202, after the host device obtains the device connection request, the device type of the current device can be determined according to the data descriptor in the device connection request. That is, whether the current device is the human-computer interaction device or the 4G module is determined, so as to control the human-computer interaction device and the 4G module, and facilitate the data transmission of the human-computer interaction device and the 4G module.

[0092] The human-computer interaction device includes but is not limited to a mouse and a keyboard. The communication mode is the communication mode of the slave device. The communication mode includes but is not limited to a CDC (Communication Device Class, abbreviated as CDC) mode, a HID mode, and a storage mode. The first processing logic is a processing logic for data communication of the 4G module when the device type is the human-computer interaction device.

[0093] As an example, in step S303, if the device type is a human-computer interaction device, the communication mode of the current device is initialized, and the first processing logic is used to perform data communication with the 4G module. In this embodiment, in some application scenarios, there is a data transmission requirement between the human-computer interaction module and the 4G module. When the host device determines that the current device is a human-computer interaction device, it initializes the communication mode of the current device. Preferably, the initialized communication mode is a CDC-type mode, and the first processing logic is used to perform data communication with the 4G module to meet the data transmission requirement between the human-computer interaction module and the 4G module. It can be understood that by using the CDC-type mode to perform data communication with the 4G module, the data transmission rate between the human-computer interaction module and the 4G module is improved based on an object-oriented structure, while also facilitating maintenance.

[0094] The first processing logic refers to the processing logic for data communication with the 4G module when the device type is a 4G module.

[0095] As an example, in step S304, if the device type is a 4G module, the second processing logic is used to perform data communication with the 4G module. In this embodiment, when the device type is a 4G module, the host device can directly use the second processing logic to perform data communication with the 4G module, thereby facilitating the host device's management of the 4G module and the human-machine interaction device.

[0096] In this embodiment, the host device acquires a device connection request, which includes a data descriptor. Based on the data descriptor, the host device determines the device type. If the device type is a human-computer interaction device, the host device initializes its communication mode and uses a first processing logic to perform data communication with the 4G module. If the device type is a 4G module, the host device uses a second processing logic to perform data communication with the 4G module. This enables control over both the 4G module and the human-computer interaction device. Simultaneously, by initializing the current device's communication mode, the host device optimizes the communication mode for data communication with the 4G module, thereby improving the data transmission rate of the 4G module.

[0097] In one embodiment, such as Figure 3 As shown, in step S203, which initializes the communication mode of the current device and uses the first processing logic to perform data communication with the 4G module, the following steps are included:

[0098] S301: Obtain target configuration parameters.

[0099] S302: Based on the target configuration parameters, set the current device mode to CDC communication mode.

[0100] S303: Based on CDC communication mode, detect the interface status of human-computer interaction devices.

[0101] S304: If the interface configuration of the human-computer interaction device is successful, a device descriptor corresponding to the human-computer interaction device is acquired.

[0102] S305: Data communication is performed on the 4G module based on the device descriptor corresponding to the human-computer interaction device.

[0103] The target configuration parameter is a parameter set by the user, and is used to configure the parameter of the CDC communication mode. The target configuration parameter includes a communication mode type and a device descriptor address. The communication mode type is the CDC communication mode. The device descriptor address is an address used to save the device descriptor.

[0104] As an example, in step S301, the host device acquires the target configuration parameter to initialize the current device based on the target configuration parameter.

[0105] As an example, in step S302, the host device sets the current device mode to the CDC communication mode according to the communication mode type in the target configuration parameter. Since the CDC mode is used to perform data communication on the 4G module, the data transmission rate of the data transmission between the human-computer interaction module and the 4G module is improved based on the object-oriented structure, and maintenance is facilitated.

[0106] As an example, in step S303, the interface state of the human-computer interaction device is detected based on the CDC communication mode. In this embodiment, the interface state of the human-computer interaction device is detected based on the CDC communication mode to determine whether the human-computer interaction device is normally connected.

[0107] As an example, in step S304, if the interface configuration of the human-computer interaction device is successful, a device descriptor corresponding to the human-computer interaction device is acquired. In this embodiment, if the interface configuration of the human-computer interaction device is successful, a device descriptor corresponding to the human-computer interaction device is acquired, and the device descriptor corresponding to the human-computer interaction device is saved based on the device descriptor address in the target configuration parameter.

[0108] Further, if the interface configuration of the human-computer interaction device is not successful, the device connection request is reacquired.

[0109] As an example, in step S305, data communication is performed on the 4G module based on the device descriptor corresponding to the human-computer interaction device. In this embodiment, the host device establishes communication between the human-computer interaction device and the 4G module based on the device descriptor corresponding to the human-computer interaction device, so as to realize data communication on the 4G module.

[0110] In the embodiment, the host device acquires the target configuration parameter, sets the current device mode to the CDC communication mode based on the target configuration parameter, detects the interface state of the human-computer interaction device based on the CDC communication mode, acquires the device descriptor corresponding to the human-computer interaction device when the interface configuration of the human-computer interaction device is successful, and finally establishes the communication between the human-computer interaction device and the 4G module based on the device descriptor corresponding to the human-computer interaction device, so as to realize the data communication of the 4G module.

[0111] In an embodiment, as shown in FIG. 4, in step S204, if the device type is the 4G module, the second processing logic is used to perform the data communication of the 4G module, including: Figure 4

[0112] S401: judging whether the 4G module is ready.

[0113] S402: if the 4G module is not ready, initializing the communication mode of the 4G module and using the first processing logic to perform the data communication of the 4G module.

[0114] S403: if the 4G module is ready, acquiring the device descriptor corresponding to the 4G module and performing the data communication of the 4G module based on the device descriptor corresponding to the 4G module.

[0115] As an example, in step S401, the host device judges whether the 4G module is ready, so as to perform the data communication of the 4G module according to whether the 4G module is ready in the subsequent steps.

[0116] As an example, in step S402, if the 4G module is not ready, the communication mode of the 4G module is initialized and the first processing logic is used to perform the data communication of the 4G module. For example, if the 4G module is not ready, the communication mode of the 4G module is set to the CDC communication mode and the target configuration parameter is acquired, so as to improve the data transmission rate of the data transmission between the human-computer interaction module and the 4G module based on the object-oriented structure, and facilitate maintenance. The communication mode of the 4G module is set to the CDC communication mode based on the target configuration parameter. The interface state of the 4G module is detected based on the CDC communication mode. If the interface configuration of the 4G module is successful, the device descriptor corresponding to the 4G module is acquired, and the device descriptor corresponding to the 4G module is used to facilitate the host device to establish the communication with the 4G module based on the device descriptor corresponding to the 4G module, so as to perform the data communication of the 4G module.

[0117] ​As an example, in step S403, if the 4G module is ready, the device descriptor corresponding to the 4G module is acquired, and data communication with the 4G module is performed based on the device descriptor corresponding to the 4G module. In this embodiment, if the 4G module is ready, the host device can directly acquire the device descriptor corresponding to the 4G module, and perform data communication with the 4G module based on the device descriptor corresponding to the 4G module.

[0118] In this embodiment, the host device judges whether the 4G module is ready. If the 4G module is not ready, the communication mode of the 4G module is initialized, and the first processing logic is used to perform data communication with the 4G module. If the 4G module is ready, the device descriptor corresponding to the 4G module is acquired, and data communication with the 4G module is performed based on the device descriptor corresponding to the 4G module. In this way, different processing manners are selected according to whether the 4G module is ready, communication with the 4G module is established, and data communication with the 4G module is implemented.

[0119] In an embodiment, as shown in FIG. 5, step S403, i.e., acquiring the device descriptor corresponding to the 4G module and performing data communication with the 4G module based on the device descriptor corresponding to the 4G module, includes the following steps. Figure 5

[0120] S501: The target interface and the target port corresponding to the 4G module are detected.

[0121] S502: If the target interface is normal and the target port is normal, the device descriptor corresponding to the 4G module is acquired based on the target port.

[0122] S503: Data communication with the 4G module is performed based on the device descriptor corresponding to the 4G module.

[0123] As an example, in step S501, the target interface and the target port corresponding to the 4G module are detected to detect whether the target interface and the target port corresponding to the 4G module are normal.

[0124] As an example, in step S502, if the target interface is normal and the target port is normal, the device descriptor corresponding to the 4G module is acquired based on the target port. If there is an abnormality in the target interface and / or the target port, the target interface and the target port corresponding to the 4G module are detected again. In this embodiment, if the target interface is normal and the target port is normal, the device descriptor corresponding to the 4G module is acquired based on the target port, so that the 4G module can be normally connected in the subsequent steps, and the reliability of data communication of the 4G module is improved.

[0125] ​As an example, in step S503, data communication is performed with the 4G module based on the device descriptor corresponding to the 4G module. In this embodiment, the host device establishes communication with the 4G module based on the device descriptor corresponding to the 4G module, thereby enabling data communication with the 4G module.

[0126] In this embodiment, the host device detects the target interface and target port corresponding to the 4G module. When both the target interface and target port are normal, the host device obtains the device descriptor corresponding to the 4G module based on the target port. This ensures that the 4G module can connect normally in subsequent steps, improves the reliability of data communication by the 4G module, and enables the host device to establish communication with the 4G module based on the device descriptor corresponding to the 4G module, thereby enabling data communication with the 4G module.

[0127] In one embodiment, such as Figure 6 As shown, step S401, which determines whether the 4G module is ready, includes:

[0128] S601: Determine if the 4G module matches the target port.

[0129] S602: If the 4G module matches the target port, determine whether the 4G module's network connectivity function is normal.

[0130] S603: If the 4G module's network connectivity is normal, then receive file upload commands.

[0131] S604: Determine whether the target file in the file upload command is complete.

[0132] S605: If the target file is complete, then the 4G module is ready.

[0133] As an example, in step S601, the host device determines whether the 4G module matches the target port in order to determine whether the 4G module is ready in subsequent steps.

[0134] As an example, in step S602, if the 4G module matches the target port, it is determined whether the 4G module's network connectivity function is normal to ensure that the 4G module's network connectivity function can be used normally. Optionally, if the 4G module does not match the target port, the 4G module and the target port are reconfigured.

[0135] As an example, in step S603, if the 4G module's network connectivity is normal, a file upload command is received. This file upload command refers to the command to upload the target file. When the 4G module's network connectivity is normal, the host device receives the file upload command output by the 4G module to determine whether the target file is complete in subsequent steps. The target file includes a device descriptor.

[0136] As an example, in step S604, the host device judges whether the target file in the file uploading instruction is complete, so as to ensure that the device descriptor in the target file is complete, thereby ensuring the reliability in the process of establishing communication with the 4G module.

[0137] As an example, in step S605, if the target file is complete, it is judged that the 4G module is ready, so that step S403 can be performed, i.e. obtaining the device descriptor corresponding to the 4G module, and performing data communication with the 4G module based on the device descriptor corresponding to the 4G module.

[0138] In this embodiment, the host device judges whether the 4G module matches the target port, and when the 4G module matches the target port, judges whether the networking function of the 4G module is normal, and when the networking function of the 4G module is normal, receives the file uploading instruction. It is judged whether the target file in the file uploading instruction is complete, and when the target file is complete, it is judged that the 4G module is ready, so as to ensure that the device descriptor in the target file is complete, thereby ensuring the reliability in the process of establishing communication with the 4G module.

[0139] In an embodiment, as shown in FIG. 7, Figure 7

[0140] S701: configuring the target port of the 4G module.

[0141] S702: detecting the data transmission state of the target port.

[0142] S703: if the target port is in the data transmission state, judging that the 4G module matches the target port.

[0143] S704: if the target port is not in the data transmission state, judging that the 4G module does not match the target port.

[0144] As an example, in step S701, the host device first configures the target port of the 4G module to judge whether the 4G module matches the target port in the subsequent steps.

[0145] As an example, in step S702, after the host device configures the target port of the 4G module, the data transmission state of the target port is detected to judge whether the 4G module matches the target port. The data transmission state refers to the state of whether the target port is transmitting data. Illustratively, the transmitted data can be a self-checking instruction, such as a self-checking instruction for detecting signal strength or starting the networking function.

[0146] ​As an example, in step S703, if the target port is in a data transmission state, it is determined that the 4G module matches the target port, which means that the target port is transmitting data, and it is determined that the 4G module matches the target port.

[0147] As an example, in step S703, if the target port is not in a data transmission state, it is determined that the target port is not transmitting data, and it is determined that the 4G module does not match the target port.

[0148] In this embodiment, the master device configures the target port of the 4G module and detects the data transmission state of the target port.
