1. An apparatus for controlling ringtone, camera, and communication functions of a mobile terminal using a Near Field Communication (NFC) chip module and an external Radio Frequency (RF) reader, the apparatus comprising:

  • an NFC chip module electrically connected to a base band chip provided in a mobile terminal, configured to perform selection such that a command data signal, received from an external RF reader via an RF antenna, is transmitted to the base band chip or a Universal Subscriber Identity Module (USIM) card of the mobile terminal, and configured to receive a result of terminal processing of the base band chip which operates in compliance with the command data signal received from the external RF reader, and configured to transmit a result of the terminal processing to the external RF reader via the RF antenna;

    the base band chip electrically connected to the NFC chip module, configured to receive the command data signal from the external RF reader, configured to change a main operation mode of the mobile terminal in accordance with a set mode of the external RF reader in compliance with the command data signal received from the external RF reader, and configured to transmit the result of the terminal processing of the mobile terminal, obtained through conversion, to the NFC chip module; and

    the USIM card electrically connected to the base band chip and the NFC chip module, configured to perform at least one of network authentication, electronic commerce, and a global roaming communication service, and configured, when a communication connection signal of the NFC chip module is received, to receive an RF-related command including an Single Wired Protocol (SWP) and process the RF-related command in compliance with the command data signal received from the external RF reader.
