Description
Technical Field
The present invention relates to the field of terminal applications, and in particular, to a method and an apparatus for implementing system upgrade.
Background
With the rapid development of terminal intelligence, many users perform system upgrade, i.e., online firmware upgrade (FOTA), on a terminal in order to improve user experience.
The existing FOTA upgrading method mainly comprises the following procedures: the terminal initiates a mobile terminal management (DM) session according to the FOTA upgrading operation actively or passively triggered by the user; the terminal reports parameters under the device information (Devinfo) node to the server; the server judges whether an available differential upgrade package exists at present according to the equipment model and the version number in the equipment information; if the differential upgrade package is contained, the server issues the DD file containing the information of the size, the download address and the like of the differential upgrade package to the terminal; the terminal downloads a differential upgrade package according to the DD file; after the differential upgrade package is downloaded, carrying out whole package verification on the differential upgrade package, and verifying a source file and a target file corresponding to each differential file to complete data correctness verification; when the verification passes, upgrading is completed; otherwise, the upgrade fails.
The correctness verification of the data is mainly related to the current system version and the source version of the terminal, if a user performs Root before FOTA upgrade and a system file is damaged, lost or tampered due to improper operation, the current system version and the source version of the terminal are different, and the correctness verification of the data cannot pass due to the difference between the current system version and the source version of the terminal, so that the FOTA upgrade fails; in addition, some terminals purchased by users through a network channel may have the problems of Root file damage, loss and tampering, and the current system version and the source version of the terminal have differences, so that FOTA upgrade cannot be successfully performed. For the above situation, if the user wants to complete FOTA upgrade, the SD card upgrade package of the complete version must be downloaded and upgraded; if the complete version of the SD card upgrade package does not exist, the device cannot complete the system upgrade.
At present, whether the current system version and the source version of the terminal are different or not can be known only when the accuracy of data is checked, and can be determined only at the final stage of upgrading. The upgrading failure causes the loss of the electric quantity and the flow of the terminal, wastes a large amount of time and energy, and influences the user experience. In addition, if the user cannot obtain the SD card upgrade package of the complete version, the terminal cannot perform system upgrade, and the user experience cannot be improved.
