FIG. 1 is a diagram illustrating a remote connection between terminals according to an embodiment of the present invention. Referring to FIG.

Basically, the terminal 110 is a device that can operate independently. For example, the terminal 110 is a device having its own communication function such as a mobile communication terminal and capable of executing / controlling an application independently.

The terminal 110 may be operated through a wired connection with the external device 120, as shown in FIG. At this time, the terminal 110 can operate using some resources of the external device 120, and can execute or control the application of the terminal 110 under the control of the external device 120. [

The terminal 110 provides the screen of the terminal 110 to the external apparatus 120 at a predetermined period according to wire / wireless connection (or combination) with the external apparatus 120, ) Can be controlled to be outputted. The terminal 110 may also control an application executed on the terminal 110 or the terminal 110 according to an input event of the external device 120. [ A method for controlling the terminal 110 in accordance with an input event of the external device 120 connected or wired by the terminal 110 or controlling an application executed on the terminal 110 has already been known to those skilled in the art And is not related to the explanation of the main points of the present invention, so a detailed description thereof will be omitted.

The external device 120 is an apparatus that can operate independently of the terminal 110 and periodically receives a screen of the terminal 110 through wire / wireless connection (or coupling) with the terminal 110, And is capable of outputting at least a part of the area. The external device 120 transmits an input event according to the inputted command to the terminal 110 when the user inputs a command for controlling the terminal 110 or an application running on the terminal 110 Control can be made possible.

For example, the external device 120 may be an electronic device such as a computer or a notebook.

Hereinafter, a method of controlling a notification message to be output through the external device 120 in a different form according to an operation state or a notification setting state when the terminal 110 is connected to the external device 120 in a wired or wireless connection will be described in detail .

Hereinafter, the screen area sharing the screen of the terminal 110 with the external device 120 will be collectively referred to as a shared screen 130 for the sake of understanding and explanation.

2 is a block diagram schematically illustrating an internal configuration of a terminal according to an embodiment of the present invention.

Referring to FIG. 2, the mobile communication terminal includes an input unit 210, a communication unit 215, a status setting unit 220, a remote management unit 225, a display unit 230, a memory 235, and a control unit 240.

The input unit 210 is a means for receiving a control command for controlling the terminal 110 or a command for controlling the execution of an application on the terminal 110 from the user. For example, the input unit 210 may include at least one key button, or may be implemented as a touch pad.

The communication unit 215 is a means for transmitting and receiving data to and from other devices via a communication network.

The state setting unit 220 is a means for setting and managing the operation state or notification state of the terminal 110. [

For example, the state setting unit 220 can receive and set the screen control state from the external device 120 through the remote management unit 225 under the control of the control unit 240. [

Here, the screen control state indicates a state in which the screen of the terminal 110 is output to the external device 120, and may be one of an active state and a minimized state.

The activation state indicates a state in which the screen of the terminal 110 is displayed in one area of the screen of the external device 120, as illustrated in FIG. Hereinafter, a screen displayed on the second terminal 110 by sharing the screen of the terminal 110 will be referred to as a shared screen. That is, the shared screen is the same screen as the terminal 110, as shown in FIG.

The minimized state is set so that the user can recognize that the application for controlling the screen of the terminal 110 to be output through the external device 120 is not displayed on the screen area of the external device 120, Indicates a state of being displayed in a minimum state on the screen of the external device 120 so that the application can be identified. In the minimized state, the screen of the terminal 110 is not displayed on the screen of the external device 120, so that the user can not check the screen of the terminal 110 through the external device 120. For example, the minimized state may be the same as the state in which the application information executed only on the window task bar is briefly displayed.

The notification setting state is a setting related to the display of the notification message, and may be any one of notification setting on (On) and notification setting off (OFF).

The notification setting On state indicates a state in which a notification message on the terminal 110 is displayed on the screen of the external device 120 that is wired or wirelessly connected (or combined).

The terminal 110 activates the display setting when a notification message is received to the terminal 110 or when a notification message is activated through a specific application.

At this time, if the control status of the screen control application is active on the external device 120, the terminal 110 confirms the control status and transmits the screen of the terminal 110 in which the notification message is displayed to the external device 120 To be displayed.

Of course, even if the screen control state is activated according to the implementation method, even if the notification message is displayed on the screen of the terminal 110, it may be controlled not to be displayed on the external device 120.

The notification setting OFF state indicates a state in which notification messages are displayed through the external device 120 when a notification message is received in the terminal 110 or when a notification message is activated through a specific application.

For example, when the notification setting is OFF (OFF), the terminal 110 may control the notification message to be prevented from being displayed on the external device 120.

However, according to another embodiment, the terminal 110 may display the notification message in a pop-up state so that the user can know whether the notification message is received (or activated) when the notification setting is off.

For example, when the display setting of the terminal 110 is in a liquid crystal off state and the notification message is received (or activated) while the control information state of the external device 120 is minimized, When the notification setting is On, a control command for changing the control information state of the external device 120 to the active state can be transmitted to the external device 120. [ Thus, the external device 120 can display the shared screen on the external device 120 in accordance with the control command of the terminal 110 (control command for changing the control information state to the active state). Then, the external device 120 can receive the notification message from the terminal 110 and display it on the active shared screen.

On the other hand, for example, the terminal 110 assumes that the display setting of the terminal 110 is in a liquid crystal off state and the control information state of the external device 120 is active. The terminal 110 changes the display setting of the terminal 110 to the liquid crystal on state in accordance with reception (or activation) of the notification message. Then, the terminal 110 transmits the screen of the terminal 110 on which the notification message is displayed to the external device 120 so that the notification message can be displayed through the external device 120. Thus, the external device 120 can display the screen on which the notification message of the terminal 110 is displayed through the shared screen.

The remote management unit 225 controls the remote control unit 225 to transmit and display the screen of the terminal 110 to the external device 120 at predetermined intervals in accordance with wire / wireless connection (or coupling) between the terminal 110 and the external apparatus 120 It is means. The remote management unit 225 may receive an input event of the input interface (e.g., a keyboard, a mouse) of the external device 120 and may control the terminal 110 according to the input event.

The remote management unit 225 may further include means for determining whether to share a notification message with the remotely connected external device 120 according to at least one of the screen control state and the notification setting state set through the state setting unit 220 to be.

For example, when the screen control state is activated and the notification message is received or activated, the remote management unit 225 displays a screen (or a notification message) on which a notification message is displayed so that it can be shared with the external device 120, (120).

At this time, the remote management unit 225 can further use the notification setting status. For example, when the notification setting state is the notification setting on state, the controller 100 controls the external device 120 to transmit a screen (or a notification message) on which a notification message is displayed so that the notification message can be shared with the external device 120, If the notification setting is off (Off), it can be controlled not to be shared through the external device 120. At this time, the remote management unit 225 may control the display of the notification message through the external device 120 in a pop-up form so that the user can know whether to receive or activate the notification message.

Of course, when the notification setting is off according to the implementation method, the remote management unit 225 may block the notification message from being shared through the external device 120. [

According to another embodiment, when the corresponding notification message is a notification message received or activated through a designated function (for example, receiving a telephone call or receiving a specific service message) or a specified application (receiving a messenger message, etc.) It may be controlled so as to be shared with the external device 120 according to the notification setting state.

According to another embodiment, when the corresponding notification message is a notification message received or activated through a specified function or a specified application, the remote management unit 225 may transmit the notification message to the external device 120 regardless of the notification setting state and / And may be blocked from being shared with.

When the screen setting state of the terminal 110 is off, the remote management unit 225 changes the screen setting of the terminal 110 to on by the control unit 240, It can determine whether to share the notification message with the external device 120 according to the screen control state and the notification setting state set by the state setting unit 220. [

According to one embodiment, when the screen setting of the terminal 110 is on, the remote management unit 225 displays a notification message (not shown) in accordance with the notification setting state regardless of whether the screen is controlled on the screen of the external device 120 May be shared with the external device 120 through the shared screen.

According to another embodiment, even if the screen setting of the terminal 110 is on, the remote management unit 225 may determine whether to share the notification message with the external device 120 according to the screen control state and the notification setting state have.

According to another embodiment, when the screen setting of the terminal 110 is on, the remote management unit 225 displays only the notification message of the specified function and the designated application, regardless of the screen control state and the notification setting state, To be controlled or blocked so as to be shared with the device 120.

The display unit 230 is a means for displaying data / stored data input through the terminal 110 in the form of time information.

For example, the display unit 230 may be a liquid crystal display (LCD).

Although the input unit 210 and the display unit 230 are included in the terminal 110 as an independent component in order to facilitate understanding and explanation of the present invention, And the display unit 230 may be provided in the terminal 110 as a single component such as a touch screen.

The memory 235 is a means for storing various applications necessary for operating the terminal 110, various data inputted / received through the terminal 110, and the like.

The control unit 240 may control the internal components (e.g., the communication unit 215, the input unit 210, the status setting unit 220, the remote management unit 225, and the external storage unit) of the terminal 110 according to an embodiment of the present invention. The display unit 230, the memory 235, and the like).

The control unit 240 may control the screen to be turned on when a notification message is received or activated while the screen setting state of the terminal 110 is off.

According to the implementation method, when the screen setting state of the terminal 110 is off and the notification message is a notification message for a specific function or a specific application, the control unit 240 displays the screen according to the notification setting state (On) or to maintain the off state (Off).

For example, the control unit 240 may set the screen setting state to be in the off state when receiving a notification message for a function or application set to be blocked by the user from receiving a notification message or activating the notification.

For example, the control unit 240 may control the screen setting to be turned on when a notification message for a function or application set to receive a notification message or an activation notification is received or activated by a user.

3 is a flowchart illustrating a method of controlling screen output of an external device remotely connected to a terminal according to an exemplary embodiment of the present invention. Hereinafter, a method for controlling whether or not the terminal 110 will share a screen with an external device 120 as an external device according to a screen control state and / or a notification setting state will be described.

In step 310, the terminal 110 receives and sets the screen control state every time the screen control state of the shared screen of the external device 120 is changed. As described above, the screen control state can be any of an active state and a minimized state.

In step 315, the terminal 110 is set to a notification setting state for the notification message. Here, the notification setting state may be any one of a notification setting on state and a notification setting off state.

In FIG. 3, step 315 is described as being performed sequentially after step 310, but step 315 may be performed independently of step 310, or may be performed prior to step 315.

In step 320, the terminal 110 detects whether a notification message is received or activated.

If the notification message is not received or activated, the terminal 110 waits at step 320.

However, if the notification message is received or activated, the terminal 110 determines in step 325 whether to share the notification message with the external device 120 according to at least one of the screen control state and the notification setting state.

This is the same as that described above with reference to FIG. 2, and thus a duplicate description will be omitted.
