S101: Obtain an NVUP file, where the NVUP file is a file for updating configuration parameters;

This step aims to obtain the NVUP file, which is a file used to update the configuration parameters in the communication module, which contains configuration information corresponding to various configuration parameters. Among them, NVUP file is a file format, which is an archive type with some additional functions, and is used for device configuration. Files in this format are typically used for one of two purposes:

(1) Update the device configuration by downloading the NVUP file built by an external tool (such as the above-mentioned configuration terminal);

(2) Backup and restore device configuration from within the firmware.

On this basis, please refer to Fig. 2, Fig. 2 is a schematic diagram of the file structure of a kind of NVUP file provided by this application, specifically including NV management header and each configuration item (Item 0 to Item N-1), wherein, NV management The header includes NVUP file version number, total number of configuration items (N), operator ID and NV version.

Wherein, the NVUP file can be obtained by constructing the corresponding configuration terminal. Specifically, the configuration terminal can obtain various configuration information about the communication module, and then build an NVUP file based on the configuration information. Thus, the communication module can obtain the NVUP file containing configuration information about itself from the configuration terminal, so as to update its own configuration parameters by using the NVUP file. Of course, the configuration terminal is a terminal device for obtaining communication module configuration information and constructing an NVUP file, such as a server, a computer, etc., and its specific type does not affect the implementation of the technical solution, and the application does not limit this.

S102: Analyze the NVUP file to obtain configuration information;

This step aims to realize the parsing of NVUP files. As mentioned above, the NVUP file is constructed by the configuration terminal based on the configuration information of the communication module. Therefore, the NVUP file must contain various configuration information about the communication module. Therefore, after the communication module obtains the NVUP file from the configuration terminal , you can parse it to obtain various configuration information about itself. Wherein, the file parsing process can refer to any one of the prior art, and the present application will not repeat it here.

The NVUP file contains various configuration information about the communication module. The configuration information is the configuration information of various configuration items in the communication module. Further, please refer to Figure 3, which is a kind of NVUP provided by this application Schematic diagram of the configuration item structure of the file.

S103: Utilize the configuration information to update the configuration parameters in the communication module.

This step is to update the communication module. Specifically, after analyzing and obtaining the configuration information about itself from the NVUP file, you can use the configuration information to update your own configuration parameters, that is, to fill in various configuration information under the corresponding storage path, thus completing Communication module update.

In one embodiment of the present application, the above-mentioned acquisition of the NVUP file constructed by the configuration terminal may include: OTA technology (Over-the-Air Technology, over-the-air download technology) or USB interface (Universal Serial Bus, Universal Serial Bus interface) Download the NVUP file from the configuration terminal.

Specifically, in order to effectively improve the success rate of communication module updates, after obtaining the configuration information from the NVUP file and before using the configuration information to update the configuration parameters, the version information can be screened and determined from the configuration information (the version information is the configuration information), and then judge whether the current NVUP file is suitable for its own software environment according to the version information. If it is suitable, it can use the configuration information to update its own configuration parameters. If it is not suitable, it can be deleted. NVUP file, and exit the update process. When the NVUP file adapted to itself is obtained, the configuration parameters are updated to realize the update of the communication module.

Specifically, a storage area, ie, the above-mentioned preset storage area, can be created in advance in the communication module, so that after the NVUP file is downloaded from the configuration terminal, it can be stored in the preset storage area. Furthermore, when the communication module receives a power-on signal for self-starting, it can transfer the NVUP file from the preset storage area to its own memory, and then use the NVUP file in the memory to update its own configuration parameters.

Wherein, the specific type of the preset storage area does not affect the implementation of the technical solution, as long as the storage of the NVUP file can be realized, which is not limited in the present application, for example, Flash flash memory can be selected to be used.
