INDUSTRIAL APPLICABILITY As described above, according to the present invention, when a user makes a telephone call while a specific application is running (for example, playing a movie or playing a game), the user can know the telephone receiving state while maintaining the execution state of the specific application , And can further communicate with the other party while maintaining the execution state of the specific application.

In particular, when the execution state of a specific application is displayed, a menu related to call processing operating in the background is displayed in one area of the display area, so that the execution of the corresponding specific application is maintained, .

That is, since the specific application can be immediately selected on the displayed screen without pressing the home button or pressing the sub menu button several times to control the call processing application running in the background, user convenience is increased.

1 is a functional block diagram of a communication terminal according to an embodiment of the present invention,
FIGS. 2, 3, 5, and 7 are flowcharts of a control of the communication terminal according to an embodiment of the present invention,
4 and 6 are examples of screens displayed on a display unit of a communication terminal according to an embodiment of the present invention,
8 is an example of a screen displayed on a communication terminal and a counterpart communication terminal according to an embodiment of the present invention, respectively.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the description of this embodiment, it is assumed that the communication terminal 100 is provided with an OEM call application, and that a separate call application or a call application is downloaded and stored in addition to the OEM call application.

Here, the OEM call application refers to a call-related application fundamentally provided at the time of launching the communication terminal 100, and a separate call application or call application (hereinafter referred to as a 'call application' to distinguish it from the OEM call application) It is assumed that the application is an application that is distinguished from the OEM call application and downloaded and downloaded from an application store or an application providing server according to a user's selection.

At least some of the functional blocks of the communication terminal 100 or the control procedures of the communication terminal 100, which will be described later, can be processed by these calling applications.

An example of a functional block of the communication terminal 100 according to an embodiment of the present invention is shown in FIG. The communication terminal 100 includes a display unit 110, a user input unit 120, an event sensing unit 130, a notification unit 140, and a call processing unit 150, as shown in FIG. And a menu display unit 160. FIG.

The display unit 110 may include a liquid crystal display (LCD) having low power consumption, for example, a moving picture according to the operation of the communication terminal 100 or a predetermined notification message or a menu. .

The user input unit 120 may be configured to include, for example, a keypad including at least one push button, or may be configured to include a touch pad that detects a touch input of a user have.

In particular, when the user input unit 120 includes a touch pad, the user input unit 120 and the display unit 110 may constitute one touch screen.

The event detection unit 130 detects a call reception event.

For example, when a call is received from a counterpart terminal, the event detection unit 130 detects an event based on the reception of the incoming call, that is, a call reception event. The call reception event may be a received call signal itself, or may be generated by a system program of the communication terminal 100 or by a call-related application (e.g., an OEM call module) provided in the communication terminal 100. [

When the event detection unit 130 detects a call reception event, the notification unit 140 maintains the operation of the first application displayed on the highest layer before the occurrence of the call reception event, And a display area of the first application or a separate area distinguished from the display area of the first application.

In this embodiment, the operation of the first application is maintained because the screen processing according to the first application is continued. That is, when the first application is a moving image playback application, it means that the moving image is continuously played and displayed on the screen.

For example, the notification unit 140 may control a call reception notification message to be displayed in a part of the display area of the first application.

Here, the fact that the first application is displayed on the highest layer before the call reception event occurs means that the first application is set as the highest layer application before the call reception event occurs.

The fact that the first application is set as the uppermost layer application may mean that the first application is set to occupy the entire screen of the display unit 110 or the display screen according to the operation of each application is superimposed and displayed It may mean that the first application is located at the uppermost layer and is set so that the user can preferentially view the display screen according to the operation of the first application without being disturbed at all by the display screen of the other application.

Further, the fact that the first application is set as the top layer application may mean that the user's touch drag input is regarded as the user input of the first application.

The layer corresponds to a logical distinction for determining the priority of superposition of the display screen.

The call reception notification message may correspond to information indicating that the call reception has occurred from the counterpart terminal, and may further include a predetermined menu for the user to select.

For example, the call reception notification message may include a menu of 'call viewing', a menu of 'call', a menu of 'refusal message', and a menu of 'hang up'. Functions performed in accordance with the selection of each menu will be described later. It goes without saying that such a menu may be displayed at a time different from the call reception notification message.

The call processing unit 150 controls the call processing in the background while allowing the operation of the first application to be maintained when the call receiving unit 150 detects a call receiving selection (for example, selection through a user input unit operation).

For example, if the call processing unit 150 has a separate call processing function, the call processing unit 150 may perform the call processing function in the background or control the OEM call application to operate in the background.

The call processing unit 150 performs the call processing in the background so as not to affect the operation of the first application.

Here, the execution of the call processing in the background means that the operation of the first application is maintained and the execution screen according to the first application is continuously displayed on the display unit 110, . However, a predetermined menu related to the call processing may be displayed in one area of the screen.

Accordingly, when the first application is a moving image playback application, the user can continuously make a phone conversation with the other party while watching the moving image.

At this time, the call processing unit 150 may silence the sound according to the execution of the first application or control the size of the sound to be automatically adjusted to a predetermined size. For example, the call processing unit 150 can request the system program of the communication terminal 100 so that the size of the sound according to the execution of the first application is lowered to a predetermined size in a state where the communication process with the other party is executed in the background have.

Since the system program adjusts the volume of the media sound (that is, distinguished from the call sound) according to the operation of a specific application, it is a known technique, and therefore, a detailed description thereof will be omitted.

For this, the call processing unit 150 may control the volume control button of the first application and the volume control button related to the call processing to be simultaneously displayed on the display unit 110. In this case, when the user selects the volume control button related to the call processing, the call processing unit 150 can adjust the voice of the calling party. When the user selects the volume control button of the first application, the call processing unit 150 ) Can adjust the size of the sound generated according to the execution of the first application.

The call processing unit 150 controls the call processing in the background while allowing the operation of the first application to be maintained when the user selects the " view " menu.

On the other hand, when the user selects the 'call' menu, the call processing unit 150 sets the OEM call application as the highest layer application, controls the screen switching, and controls the call processing by the corresponding OEM call application.

Here, the OEM call application may correspond to one module included in the call processing unit 150 or may correspond to a separate call module provided at the time of release to the communication terminal 100 as described above .

Setting the OEM call application as the top layer application to control the screen switching means that the reproduction of the first application is interrupted and the part where the display screen according to the execution of the OEM call application and the display screen according to the execution of the first application overlap, It may mean that the display screen according to the execution of the application is displayed in priority. For example, the display screen according to the execution of the OEM call application may completely cover the display screen according to the execution of the existing first application.

In addition, when the user selects the 'reject message' menu, the call processing unit 150 can transmit the reject message to the other party using a text message or the like. If the user selects the ' May forcibly terminate a call from the other party.

The 'call' menu, the 'talk while talking' menu, and the like can be displayed on the display unit 110 by the predetermined menu display unit 160. These menus correspond to selection items for performing the call processing according to the present embodiment. The menu display unit 160 further displays a list of menu items after the above-described ' The execution state is maintained and an image according to the first application is displayed on the display unit 110 and at the same time a menu related to call processing is displayed in a region of the display unit 110 while the call processing is being performed in the background It is possible.

At this time, the menu display unit 160 may control the menu related to the call processing to be displayed only when the user has a selection - for example, when the user touches or taps a predetermined menu displayed on the display unit 110 .

In displaying the menu related to the call processing, the menu display unit 160 may reduce the display area of the existing first application and display the menu related to the call processing in the remaining area, or may display the menu related to the call processing in the first application Or may be displayed on a part of the display area. At this time, the menu display unit 160 may perform a transparency process of a predetermined value in the menu related to the first application call process, so that an image of the display area of the first application overlapped can be displayed.

That is, if the transparency processing is not performed on the menu related to the call processing, the content such as the image of the first application overlapped with the menu related to the call processing is hidden from view, but the transparency processing of the predetermined value is performed The display image of the first application is visible even in the overlapped portion.

Here, the call processing related menu means an object for selecting a specific function, and may mean a specific area that the user can select, or may include at least one menu item for detailed selection . At this time, the call processing related menu may include a menu item for exchanging or sharing predetermined information with the communication partner.

When any one of the touch of the user's specific position and the touch drag input is detected on the menu, the function execution unit can terminate the call process being performed in the background.

As a specific example, the call processing related menu may include a 'call volume automatic adjustment menu item' and an 'information sharing menu item'.

Meanwhile, the function performing unit performs the selected function when there is a user's selection (touch input) with respect to the call processing related menu.

For example, when the selection of the 'call volume automatic adjustment menu item' is detected, the function performing unit automatically changes the call volume size according to the size of the ambient noise inputted through the current microphone (not shown).

At this time, the function performing unit can determine the size of the surrounding noise by using the size of the sound input in the predetermined noise frequency band.

For example, when talking with the other party, the user inputs a voice through the microphone. The function performing unit can distinguish the user's voice and surrounding noise using the frequency band. In this case, by checking the size (db) of sound input in a band other than the user's voice frequency band (i.e., voice frequency band), it is possible to determine the magnitude of ambient noise in real time during a call with the other party.

To this end, the user voice frequency band may be registered in advance. For example, when the user inputs a voice through a selection of a specific menu in a place where there is no noise, the communication terminal 100 can determine the frequency band of the inputted voice and register it in the voice frequency band of the user.

In the above-described embodiment, the function performing unit distinguishes between the user's voice frequency band and the surrounding noise frequency band to determine the size of the ambient noise. However, if the user delays the voice input start time, It is also possible to judge the noise level.

For example, the function performing unit may determine the surrounding noise level by using all the sound signals input through the microphone for a predetermined time (for example, one second) from the time when the user selects the 'automatic volume adjustment menu item' The user may continue to communicate with the other party after the predetermined time has elapsed.

When the selection of the 'information sharing menu item' of the user is detected, the function performing unit extracts and displays the transfer data stored in the storage unit (not shown), and transmits the displayed transfer data to the communication partner according to the user's selection .

Here, the 'information sharing menu item' may include at least one of a 'schedule sharing item', a 'to-do sharing item', and a 'message sharing item'.

Here, the 'schedule sharing item' is for sharing the schedule stored in the calendar in the communication terminal 100 with the communication partner, and the 'task sharing item' is included in the to-do list in the communication terminal 100 The 'message sharing item' is for sharing the message stored in the message box in the communication terminal 100 with the communication partner.

The calendar, the to-do list, and the message box provided in the communication terminal 100 are only known ones, so a detailed description will be omitted.

Hereinafter, a control flow of a communication terminal according to an embodiment of the present invention will be described with reference to FIG.

First, the first application is set as a top layer application and executed (step S1).

Setting the uppermost layer application here may mean simply controlling the application that is executed in the foreground to be displayed at the topmost layer of the display unit 110 at the end.

The first application set in the top layer application may be an application that plays a predetermined multimedia file or a game application, but in this embodiment, the first application is a TV (Television) viewing application.

In this state, the user can watch the TV program in real time using his / her communication terminal 100. [

When the call reception event is detected (step S3), the communication terminal 100 displays a call reception notification message in one of the areas where the TV broadcast screen is displayed while the execution of the TV watching application is maintained (step S5).

After the call reception notification message is displayed, if the user selects to receive the call (step S7), the communication terminal 100 executes the call processing function in the background (step S9) Do not affect operation.

At this time, the communication terminal 100 displays a call processing related menu in one of the first application display areas (step S11). At this time, the communication terminal 100 may perform a predetermined transparency process on the menu related to the call processing to display an image of the first application in the lower layer.

The description of the transparency processing on the image of the overlapping portion is merely well known, and therefore, a detailed description thereof will be omitted.

As described above, in the state where the TV broadcast program is displayed according to the operation of the first application, that is, the TV watching application, menus related to the call processing executed in the background are displayed in a partial area of the display unit 110, The user can make a call with the other party while continuing to watch the call, and furthermore, the call-related specific functions can be performed by selecting or operating the menus displayed on the screen.

Hereinafter, a specific example of the process according to the selection of the user in the state that the menu related to the call processing is displayed as described above will be described.

Referring to FIG. 3, when touch-dragging is detected in the menu display area of the user (step S23) while the menu related to call processing is displayed (step S21) If there is (step S25), the communication terminal 100 performs call termination processing (step S27).

4 (a) shows a situation when the user finishes the call processing by touching and dragging in the menu display area 111, and FIG. 4 (b) shows a state in which the user selects the call termination menu item 113, And the process is terminated.

It goes without saying that the communication terminal 100 can control the menu display area or the menu item to disappear after performing the call termination process.

5, when the menu related to the call processing is displayed (step S31) and the user selects the menu item for automatically adjusting the call volume (step S33), the communication terminal 100 determines the surrounding noise level (Step S35).

The process of determining the surrounding noise level may use the size of a sound input in a specific frequency band that avoids a voice frequency band of a predetermined user.

Then, the communication terminal 100 automatically adjusts the call volume according to the determined ambient noise level (step S37). Here, the automatic adjustment of the call volume may mean that the intensity of the signal received from the other party is adjusted to be output to the speaker or the like, or the size of the signal input through the microphone and transmitted to the other party may be adjusted.

6 shows a state including a 'volume automatic adjustment' menu item 115, a 'schedule sharing' menu item 116, a 'task sharing' menu item 117, and a 'message sharing' menu item 118 , The communication terminal 100 performs the process of FIG. 5 when the user selects the menu item 'automatic volume adjustment' by touching or the like.

In FIG. 6, the state information 114 related to the call is displayed in one area of the display screen on which the first application is executed, as well as the menu items 115 to 118, as described above. The status information 114 related to the call may include a telephone number of the calling party, a call duration, a name of the calling party (obtainable from information matched with the telephone number in the address book) Processing may be performed so that the overlapped area of the display area 112 of the first application is displayed.

FIG. 7 shows a process of processing when a user selects a 'schedule sharing' menu item among the menu items shown in FIG.

That is, when the user selects the 'schedule sharing' menu item (step S41), the communication terminal 100 extracts the schedule data stored in the calendar as the transfer data and displays it in one area of the screen (for example, One of the display areas) (step S43).

Here, the calendar is an area of a kind of application or storage unit for registering and managing the schedule of the user of the communication terminal 100, and is mostly provided in recent mobile phones and smart phones, and thus a detailed description thereof will be omitted.

An example in which the schedule data stored in the calendar is displayed in one area of the display unit 110 is shown in Fig. 8 (a).

When at least one of the schedule data 119 is being displayed as shown in the figure, if the user selects at least one of them, the communication terminal 100 transmits the selected schedule data to the called party (step S45).

At this time, the communication terminal 100 may transmit the displayed schedule data to the counterpart terminal in the form of a short message. For example, the communication terminal 100 can confirm the phone number of the called party and transmit a text message containing the contents of the predetermined data to the confirmed calling party terminal.

Accordingly, the communication partner terminal can display a text message including the received schedule data as shown in FIG. 8 (b), and register the text message on the calendar according to the selection of the corresponding terminal user.

Accordingly, it is possible to share the schedule with each other while the user is in the process of talking with the other party.

The case where the user selects the 'task sharing' menu item or the 'message sharing' menu item may be similar to the schedule sharing process described above. That is, only the type of data to be extracted is different, and the process of transmitting the extracted shared data to the counterpart terminal is the same as that of the user, so duplicate explanation is omitted.

In the above-described embodiments, the use of the menu displayed when the first application maintains the operation and the call processing proceeds in the background has been mainly described. However, when the menu for selecting whether the call processing proceeds in the background is transmitted to the communication terminal 100 ). ≪ / RTI >

For example, when a call is received from the other party, a 'call' menu and a 'call view' menu may be displayed automatically or in accordance with a user's selection in one area of the display area while the operation of the first application is maintained.

In this state, the user can select a desired menu. For example, when the user selects the 'call' menu, the communication terminal 100 can execute the OEM phone application corresponding to the installed basic phone application.

At this time, the interface screen according to the execution of the OEM phone application is displayed on the communication terminal 100, and the communication with the other party can be performed by the function of the OEM phone application.

In this case, the communication terminal 100 can suspend or terminate the execution of the TV viewing application.

On the other hand, when the user selects the 'view while talking' menu, the communication terminal 100 executes the call processing function in the background so that communication with the other party is performed, but the operation of the TV viewing application is not affected.

That is, the user can continue to watch the TV program he / she was watching while talking with the other party.

At this time, the communication terminal 100 may silently process the sound generated by the TV viewing application even if there is no manual operation by the user, or adjust the sound size to be less than a predetermined size.

Needless to say, the process of performing each of the above-described embodiments can be performed by a program stored in a predetermined recording medium (for example, a computer readable medium).

The present invention is not limited to the above-described specific embodiments, and various modifications and changes may be made without departing from the gist of the present invention. It is to be understood that such variations and modifications are intended to be included in the scope of the appended claims.
