APPARATUS AND METHOD FOR FIRMWARE UPDATE IN A PORTABLE TERMINAL
First Claim
1. An apparatus for performing firmware update in a portable terminal, the apparatus comprising:
- a controller for processing to receive a device management command from an update server, the device management command including information indicating the execution or non-execution of a firmware update and checksum information for delta information, and for performing the firmware update; and
a command analyzer for analyzing the received device management command and for, if update execution is necessary, determining if the delta information is information valid for the portable terminal based on the checksum information, before receiving the delta information.

Abstract
An apparatus and method for downloading an update file using a Firmware Over The Air (FOTA) service of a portable terminal are provided. The apparatus includes a controller and a command analyzer. The controller processes to receive a device management command from an update server, the device management command including information indicating the execution or non-execution of update and checksum information for delta information, and performs the firmware update. The command analyzer analyzes the received device management command, and if update execution is necessary, the command analyzer determines if the delta information is information valid for the portable terminal based on the checksum information, before receiving the delta information.
