Method for limiting a data storage function in a mobile communication terminal
First Claim
1. A method for limiting a data storage function of a mobile communication terminal in a mobile communication system, comprising the steps of:
- generating, by a base station, a message including information for controlling the data storage function of the mobile communication terminal when the mobile communication terminal enters an area, covered by the base station, where the data storage function is limited;
transmitting, by the base station, the message to mobile communication terminals located in the area; and
setting a data storage limiting mode in the mobile communication terminal.

Abstract
A method for limiting a data storage function in a mobile communication terminal. When entering an area (such as a secure area) where the data storage function is limited, the mobile communication terminal receives, from a base station located in a secure area, a message indicating that the mobile communication terminal is currently located in the secure area. The mobile communication terminal then analyzes the received message, determines whether it is currently located in the secure area, and sets and stores file system control information such that data generated when a supplementary function is performed cannot be stored. Even when a user who fails to determine that he or she is in the secure area uses the supplementary function of the terminal, the data is not actually stored, such that security can be maintained in a specific area.
