Embodiment Construction

[0028] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] In the embodiment of the present invention, the user terminal is pre-configured such as figure 2 Shown is used for the storage space of firmware upgrade processing, and this storage space is divided into boot area (boot area also is boot loader) and file system management area, and this file system management area is divided into the first OS (Operating System, operating system) area, FS (File System, file system) area and the second OS area, wherein:

[0030] Boot loader, used to store version boot information corresponding to each firmware in the user terminal.

[0031] The version guide information can be a field (for example, when the value of the field is 1, it indicates that the user terminal adopts an upgraded version of the firmware; when the value of the field is 0, it indicates that the user terminal adopts an unupgraded version of t...

Abstract

The invention discloses a method and a device for realizing wireless firmware update, aiming at solving the problem that a user terminal can not be used because of the failed updating of the firmware to be updated in the prior art. The method comprises the following steps: receiving the update notice sent by a device management server; obtaining a differential packetization corresponding to the firmware to be updated from the device management server according to the hardware update notice; and adopting a set update mode, generating an update edition of the hardware to be updated in a storage space allocated for hardware update treatment according to the differential packetization, and storing the update edition in the storage space. By adopting the technical scheme, the invention improves the update effectiveness of the hardware and the backoff efficiency of an update zone.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for realizing wireless updating of firmware. Background technique [0002] At present, with the increasing popularity of mobile communication terminals, the types of mobile communication terminals are becoming more and more abundant, and the types of software / firmware in mobile communication terminals are also becoming more and more abundant. For operators and terminal equipment manufacturers, how to be more Effective management of mobile terminals to reduce the impact of software / firmware defects on mobile communication terminals on users and ensure stable use of user terminals has become one of the technical problems that need to be solved urgently. [0003] At present, the management of mobile terminals is mainly realized through FOTA (Firmware Over The Air, firmware wireless update) technology. Since FOTA technology can not only download and upgrade app...
