Embodiment Construction

[0057] The basic idea of ​​the present invention is: a uniquely designed upgrade package and an upgrade process are proposed, and by analyzing the downloaded upgrade package of the combined device, an upgrade operation is performed on the combined device by using a corresponding upgrade method according to the different structures of the upgrade package.

[0058] Here, the combined device is composed of a master sub-device and a controlled sub-device; the upgrade method includes an upgrade method with verification and an upgrade method without verification, wherein the upgrade method with verification is further divided into: Parallel upgrade methods, serial upgrade methods, and step-by-step upgrade methods with rollback.

[0059] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0060] The exclusive Flash combination device FOTA device of the present invention includes: a download and anal...

Abstract

The invention discloses a method for the firmware over-the-air (FOTA) of exclusive flash memory (Flash) combined equipment, which comprises the following step: downloading and analyzing upgrade package of the combined equipment from a server and determining the structure of the currently downloaded upgrade package; and according corresponding upgrade modes corresponding to different structures ofthe upgrade package to execute the upgrade operation of the combined equipment. The invention also discloses a device for the FOTA of the exclusive Flash combined equipment. The method and the devicecan upgrade the combined equipment consisting of two sets of subequipment. The upgrade package downloading and the upgrade result report processes in the FOTA method of the invention are the same as that of the prior art, so the method has excellent compatibility with the prior server, and consequently network resources are saved.

Description

technical field [0001] The invention relates to a firmware over the air (FOTA, Firmware Over The Air) technology, in particular to a FOTA method and device for a terminal-exclusive flash memory (Flash) combined device. Background technique [0002] With the development of mobile communications, especially Time Division Synchronous Code Division Multiple Access (TD-SCDMA) networks, terminals are no longer simple communication tools. Existing terminals integrate multimedia, personal information management and entertainment functions, and have become As complex as a personal computer. Moreover, as the period for terminal manufacturers to launch new product functions is getting shorter and shorter, the period for operators to launch new services will also be shorter and shorter. Therefore, terminal manufacturers are required to provide users with simple and effective upgrade services. [0003] At present, FOTA has received more and more attention as a method for remotely managi...
