Abstract

A firmware over the air (FOTA) upgrade method for exclusive flash compound device, comprises: downloading an upgrade packet for a compound device from a server and parsing it, determining the structure of the current downloaded upgrade packet; performing an upgrade operation for the compound device by using a corresponding upgrade mode according to the different structure of upgrade packets. An FOTA upgrade apparatus for exclusive flash compound devices is also disclosed. The method and apparatus can implement upgrade for the compound device including two sub-devices, and the processes of downloading upgrade packets and reporting upgrade results in the FOTA upgrade method and in the prior art are identical.

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...
