Devices can be upgraded and maintained by upgrading system software, managing patch, and activating GTL license files.
System software upgrade and patch installation
GTL file update
You can select a proper operation to upgrade and maintain the device according to the real-world situation. Application scenarios of these operations are as follows:
Upgrade
System software upgrade
System software upgrade can optimize device performance, add new features, and upgrade the current software version.
Patch installation
Patches are a type of software compatible with system software. They are used to fix urgent bugs in system software. You can upgrade the system by installing patches, without having to upgrade the system software.
GTL file update
A GTL file controls all resource and function items that can be used by a device. All service features that have been configured on devices can be enabled only when a GTL file is obtained from Huawei. GTL file update does not require software upgrade or affect existing services.
To add new features to a device or optimize device performance, or if the current resource files (including the system software and GTL file) do not meet requirements, you can choose to upgrade software, install patches, or update the GTL file as needed.
