摘要： A method for managing software of a terminal in a device management system is provided. The device management server identifies if the memory area required for downloading and installing software is ensured in the terminal when the device management server has the software to be downloaded to the terminal. Then, the device management server acquires at least one among a usage rate during a predetermined period of time, a last use time, and a total number of times of usage for each software installed in the terminal when the required memory area is not ensured in the terminal. Next, the device management server selects software to be removed based on the usage rate, the last use time, etc., and notifies the terminal of the selected removal-targeted software. Then, the terminal removes the removal-targeted software when the terminal receives a removal acceptance input of the removal-targeted software from the user, and notifies the device management server of a result of the removal. Thereafter, the device management server transmits the software to be downloaded to the terminal.
