Problems solved by technology

At present, the device adopts the function of resuming uploading from breakpoints. After the device is disconnected from the network, it will continue to download the upgrade package when it is connected to the network, so as not to download repeatedly; There will be a high probability of signature errors, which will make it impossible to determine whether the update package is a security update package, and also cause the update to fail

Embodiment Construction

[0039] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0040] When the Android device is upgrading firmware over the air (FOTA, Firmware Over the Air), it needs to download an upgrade package from a remote location. During downloading, the device needs to have the function of resuming uploads from breakpoints, in case the device needs to download the upgrade package again after the device is disconnected from the network during the download process; for device security, the device needs to verify the signature information of the downloaded upgrade package to prevent the package from being illegal. Issued by the company. In practice, when the device is disconnected from the network, there will be a breakpoint resume function, and the upgrade package can continue to be downlo...

Abstract

The invention discloses a power-off continuous transmission upgrading method and a terminal system thereof, which are suitable for a terminal system, and the method comprises the following steps: S1, downloading an upgrading packet, and caching a data stream into a buffer pool of a memory; s2S2, when the length of the currently cached data stream does not meet the size of a buffer pool, forcibly writing the cached data stream into a user-defined continuous transmission file, and updating and marking a file downloading starting point and a file storage starting point in real time by the continuous transmission file through a file recording pointer according to the writing of the data stream; and S3, if the power failure restart occurs, continuing to download the upgrade package according to the file download starting point, and continuing to store the data stream according to the file storage starting point. Through the implementation of the method and the device, the breakpoint resume is prevented from continuously downloading the upgrade package data after power failure and restarting, the upgrade problem appearing in the power failure and downloading process is solved, the upgrade function of the Android intelligent equipment is perfected, and better experience is brought to a user.

Description

technical field [0001] The invention relates to the field of computer network communication, in particular to an upgrade method for continuous transmission after power failure and a terminal system thereof. Background technique [0002] Android smart devices are indispensable for remote maintenance and update. Remote update requires downloading the update package and then upgrading; for device safety, the signature of the update package will be verified before the update. At present, the device adopts the function of resuming uploading from breakpoints. After the device is disconnected from the network, it will continue to download the upgrade package when it is connected to the network, so as not to download repeatedly; There will be a high probability of signature errors, which will make it impossible to determine whether the update package is a security update package, and also cause the update to fail. Contents of the invention [0003] The technical problem to be sol...
