Terminal and method for performing device management scheduled based on threshold

Abstract

Commands for device management to be executed within a terminal and threshold-based conditions for executing such commands included within a scheduling context are provided to the terminal ahead of time. Therefore, the terminal can perform the commands for device management, before errors occurs within the terminal since a value of a particular management object reaches the threshold.
