A method and apparatus for upgrading software in a Customer Premise Equipment (CPE) that exchanges Inform messages with a server over an Internet Protocol (IP) network are provided. The software upgrade method includes, upon receiving a download request message from an Automatic Configuration Server (ACS) remotely controlling the CPE, rebooting in an upgrade mode after storing upgrade execution information included in the download request message, acquiring a software image for upgrade from an upgrade server based on the stored upgrade execution information after rebooting in the upgrade mode, updating an old software image with the acquired software image, and rebooting in a normal mode after completing the update of the old software image. |
