System and method for controlling a mobile terminal

A method of controlling a mobile terminal in a mobile terminal control system, the mobile terminal control system including the mobile terminal and an external terminal, the mobile terminal including a memory, a Near-Field Communication (NFC) controller for NFC interface, and a base-band chip for controlling individual components of the mobile terminal, the external terminal communicating with the NFC controller of the mobile terminal, the method comprising:

• at the base-band chip, registering an Application Identifier (AID) of at least one application that operates in the mobile terminal, in the NFC controller;
• at the NFC controller, receiving an instruction for selecting a registered AID from the external terminal and notifying the base-band chip that the AID has been selected;
• and
• at the base-band chip, executing an application corresponding to the AID selected by the external terminal to thereby restrict a predetermined function of the mobile terminal or release function restriction according to conditions setting information received from the external terminal,
• wherein the conditions setting information includes access control information for storing new information in the memory, information for controlling a call function, and setting information regarding ring back tone that is heard by a sender when the call function is restricted, and
• in response to the mobile terminal receiving a call from a sender, the application selected by the external terminal prevents a bell sound from being played at the mobile terminal, provides the sender with a ring back tone, according to a specific region of the mobile terminal, indicating that the bell sound is being restricted at the mobile terminal located at the specific region, and provides the sender with an option to force the bell sound to be played at the mobile terminal.
