Software update system, firmware over-the-air update system, and method for updating client device

摘要

The software update system includes a client device (104) having non-OS system software (110) to be updated and a client update server that is remotely located from the client device (104) and can communicate with the client device (104) (102) and a device capability manager (126) for accessing capability data relating to the client device (104). The update server (102) searches for a first update required to update at least a part of the software (110). The update server (102) includes an update optimizer (124) that cooperates with the device capability manager (126) to determine an organization scheme for applying the first update that optimizes the update of the client device. The organization scheme is compatible with the technical capabilities of the client device (104), and the update optimizer (124) recovers the first update from the instance of the first update organized according to the selected organization scheme. Identify the recovery function to be used. The device capability manager (126) uses the capability data to determine the necessary functionality required to perform the identified recovery function. The update server (102) comprises an update package generator (116) in response to an update optimizer (124) that generates an update package comprising a second update that enables the client device (104) to support a recovery function. .
