The ZTE Terminal Software Update Framework is built around a modular architecture that includes several key components: zte terminal software update framework
Traditional OTA updates often relied on a Device Management (DM) session to initiate the process. ZTE has innovated in this area by patenting a method and system for "initiating a terminal operation" that enables , effectively removing the dependence on a DM session. The patent describes "a server encapsulating firmware update information for initiating a terminal to carry out a Firmware over the Air (FOTA) operation" and "the server sending a Push message to the terminal and carrying the firmware update information in the Push message." This approach "can avoid the dependence of the FOTA operation on the Device Management (DM) session and reduce the redundant data amount caused by the DM session." file to the root directory of an SD
One of the most critical technologies for efficient updates is the approach. Instead of requiring users to download a full firmware image, ZTE's framework generates update packages containing only the difference between the current and new software version. A patent owned by ZTE discloses a method where "the upgrade package only including the difference between the bytes is used to achieve the software updating of the terminal, which is suitable for the software updating based on the wireless and can save much traffic for the user". This approach is crucial for modern networks, significantly reducing bandwidth consumption and improving update delivery speeds. The patent describes "a server encapsulating firmware update
