The present invention relates to a mobile terminal using Wi-Fi Direct and an application interworking method thereof.

The mobile terminal may be configured to perform various functions. Examples of such various functions include data and voice communication functions, taking pictures or videos through a camera, storing voices, playing music files through a speaker system, and displaying images or videos. Some mobile terminals include additional functionality to play games, while others are implemented as multimedia devices. Moreover, recent mobile terminals can receive broadcast or multicast signals to watch video or television programs.

Further, efforts for supporting and increasing the functions of the mobile terminal continue. The foregoing efforts include not only changes and improvements in the structural components forming the mobile terminal, but also improvements in software or hardware.

9 is a flowchart illustrating an application interworking method of a mobile terminal using Wi-Fi Direct according to an embodiment of the present invention.

As shown in FIG. 9, the user executes Wi-Fi Direct from the user menu of the mobile terminal (S10). The Wi-Fi Direct may be operated in two forms.

The first method is to select and execute a predetermined application after executing Wi-Fi Direct, and the second method is to execute the Wi-Fi Direct while executing a predetermined application. In particular, when the Wi-Fi Direct is executed using the second method, only a device supporting the application is searched (scanned) and displayed on the screen, thereby increasing usability. 9 corresponds to the first method.

Once Wi-Fi Direct is executed from the menu, the controller 180 displays the Wi-Fi Direct UI stored in the memory 160 on the screen (FIG. 4A). At this time, the Wi-Fi Direct UI is activated by entering the ON state from the beginning or by setting the switch button to "On" in the Wi-Fi Direct UI. If the Wi-Fi Direct UI is activated (when turned on), a search (scan) of all devices around the connectable peripheral area is automatically executed (S20) (FIG. 4B).

When the search is finished, the controller 180 displays the peripheral devices that can be connected according to the user setting (signal strength, priority, user setting, etc.) (S30). When the user selects a specific device from the device list, the controller 180 searches for an application (or service) that can be connected to the corresponding device, and then checks the number of the found applications (S40 and S50). If there is more than one application found as a result of the check, the controller 180 provides a selection menu (Fig. 7) for selecting a specific application on the screen (S60), and executes the application finally selected by the user on the selection screen (S70). ).

On the other hand, when there is only one searched application, the controller 180 automatically executes the corresponding application (S80).

As described above, the present invention displays the application (or service) commonly supported by the searched mobile terminal and the searched device when executing Wi-Fi Direct in detail information (before connecting to a specific device), and after connecting with a specific device. If there is only one supported service, the service application is automatically executed. If there are multiple supported services, a selection screen is provided to execute the application after the user selects it.
