Dual OS system using a smart SIM module and controlling method thereof

摘要

A computer system, and more particularly, to a system and controlling method thereof are disclosed, by which a plurality of operating systems can be driven using a smart subscriber authentication module. The present invention includes at least one display unit, a first memory provided with a first operating system, a subscriber identification module (SIM) including a second memory provided with a second operating system different from the first operating system and a second controller configured to perform an operation for the second operating system, and a first controller determining whether the subscriber identification module is connected via a prescribed interface, the first controller, if determining that the subscriber identification module is connected, controlling a booting of the first operating system or a booting of the second operating system through the operation by the second controller to be selectively executed on the at least one display unit.

1. A computer system comprising:
at least one display unit; a first memory storing a first operating system; a subscriber identification module (SIM) comprising:
a second memory storing subscriber identification information and a second operating system different from the first operating system; anda second controller configured to perform an operation for the second operating system; a first controller controlling a booting of the first operating system or the second operating system through the operation by the second controller, a first modem connected via an interface to be driven by the first operating system; and a second modem connected via an interface to be driven by the second operating system; wherein the display unit displays information identifying which operating system is being booted, wherein the first operating system comprises an x86-series operating system driven in a general computer system, wherein the second operating system comprises a Linux-series mobile operating system, wherein the second modem comprises a mobile communication modem, wherein the second operating system is installed in the SIM, a selection window for selecting the first operating system or the second operating system is displayed on the display unit, and the second operating system is booted by an operation of the second controller of the SIM when a user selects the second operating system to be booted, wherein the first operating system is automatically booted when the first controller determines that the SIM is not recognized or the second operating system is not loaded in the SIM, wherein the first controller controls the second modem to perform a data communication, extracts a mobile content stored in the SIM and converts a file format of the mobile content into a format recognizable by the first operating system when a user executes an application for emulating a mobile communication terminal operating in the first operating system.
