Here, the storage medium may be a memory card having a storage space capable of storing data such as a file stored by a user, or a universal subscriber identity module (USIM) which is a universal subscriber identity module storing user authentication information. Or a SIM card (Subscriber Identity Module).

Meanwhile, in step S100, the controller 180 may perform data communication after electrically connecting an external storage medium through the interface 170, or the short range communication module of the wireless communication unit 110 (see FIG. 1). After connecting wirelessly through 114, data communication may be performed. Here, when the wireless communication using the short-range communication module 114, it may be connected by NFC (Near Field Communication) method or Bluetooth (Bluetooth) method.

As described above, when data communication with an external storage medium is performed through the wireless communication unit 110 or the interface unit 170, the controller 180 recognizes the storage medium through the data communication, and recognizes the storage medium. To detect the identification information (S200).

Here, 'recognizing the storage medium' means that the storage medium is connected to the terminal main body 100 through the wireless communication unit 110 or the interface unit 170, and is in a state in which data can be exchanged with each other. it means.

In addition, the 'identification information' may include the storage medium such as the type, capacity, manufacturer, use, standard, communication method, type of stored data, usable state, communication state, and reception sensitivity of the storage medium. It can be various kinds of information that can determine whether it is suitable for communication.

For example, as shown in FIG. 4, when the storage medium 200 included in the external device 300 connected to the outside is connected to the main body 100, the controller 180 controls the storage mediums 210, 220, and the like. The storage medium 210, 220, 230 is recognized through data communication with the 230. Here, the external device 300 may include a plurality of storage media 210, 220, 230.

In addition, as described above, when the storage medium is recognized, the controller 180 may display icons 410, 420, and 430 corresponding to the storage medium recognized through the display window 400 in one area of the display unit. In addition, although not shown in FIG. 4, the display window 400 may display identification information of recognized storage media, and when a user's selection is input to any one of icons displayed on the display window 400. The identification information of the storage medium based on the icon corresponding to the selection may be displayed.

In addition, the controller 180 determines a function that the main body 100 can perform through the recognized storage medium using the identification information (S300, see FIG. 3).

Herein, the term 'performable function' means that when the recognized storage media 210, 220, 230 communicate with the main body 100, the main body 100 uses the storage media 210, 220, 230. This refers to the function that can be performed.

For example, as shown in FIG. 4, when the first storage medium 210 is a 'memory card', the controller 180 communicates with the first storage medium 210 to control the body 100 of the main body 100. Data may be stored in the first storage medium 210.

As another example, when the second storage medium 220 is a 'simsim card', the controller 180 can obtain subscriber identification information of the main body 100 through communication with the second storage medium 220, When the main body 100 communicates with another mobile terminal, subscriber identification information included in the second storage medium 220 may be used.

As described above, if a function is determined based on the identification information of the recognized storage media 210, 220, 230, the controller 180 performs the determination through continuous communication with at least one of the storage media. The function is controlled to be performed (S400).

Here, the storage medium for continuous communication with the main body 100 may be selected by the user, as shown in FIG. 4, and may be determined by the controller 180.

If determined by the controller 180, the controller 180 may determine a function currently being performed by the main body 100, and select a storage medium most suitable for the determined function based on the identification information of the storage medium.

In addition, as shown in FIG. 4, when any one of the recognized first to third storage media 210, 220, 230, for example, the second storage medium 220 is selected by the user, the controller ( 180 may control the second storage medium and the main body 100 to perform continuous data communication.

In this case, the controller 180 allows the main body to perform a function through the second storage medium 220 based on the function determined through the identification information of the second storage medium 220. 2 If the storage medium 220 is a SIM card, the main body 100 communicates with an external mobile terminal by using subscriber identification information of the second storage medium 220.

In this case, whether the first and third storage media 210 and 230 recognized together with the second storage medium 220 are continuously recognized and whether or not data communication is maintained may be maintained according to the controller 180 or the selection of use. , Can be terminated.

In addition, the controller 180 may indicate that the second storage medium is connected to one area of the display unit 151 to provide information of the storage medium connected to the user.

Meanwhile, a plurality of storage media connected to the main body 100 and performing a function may be provided.

As described above, the mobile terminal and its control method according to an embodiment of the present invention can achieve the same effect as using a storage medium provided therein through communication with a storage medium not provided in the terminal body. have.
