The antenna unit 110 transmits a transmission signal (for example, a user's voice signal, a telephone call request, a wireless Internet connection request, etc.) received from the wireless circuit unit 115 to a mobile communication service system (not shown) through a communication network. In addition, the wireless signal is received from the mobile communication service system (for example, a voice signal of another user, sound source data according to a download request of the user), and transmitted to the wireless circuit unit 115.

The wireless circuit unit 115 receives a voice signal, a message, and the like from the mobile communication service system through the antenna unit 110 and transmits it to the controller 150, and a user command through the input unit 135 under the control of the controller 150. (For example, an operation command corresponding to a key selection) and / or a voice signal of a user input through the handset 125, is transmitted to the antenna unit 110.

The audio processor 120 processes the voice input by the user of the mobile communication terminal 100 through the handset 125 as data and transmits the data to the controller 150, and transmits the voice signal received through the antenna unit 110. Processing to output the analog voice through the handset 125. In addition, when the external input / output device 160 is coupled to the mobile communication terminal 100 by wire or wirelessly, the audio processor 120 may output a sound to be output through the handset 125 under the control of the controller 150. , An audio signal, an MP3 data play signal, an effect sound according to game play, etc.) may be output through the external input / output device 160.

The handset 125 may include a handset such as a microphone and a handset such as a speaker. The microphone is a means for receiving a voice of the user of the portable terminal 100, and the speaker is a voice signal of another user received from the mobile communication service system through the antenna unit 110, and any key button provided in the input unit 135 is selected. Means for outputting a corresponding sound, MP3 data reproduction sound, and the like.

The display unit 130 displays an operation state, an application execution screen, time information, a received message, and the like of the portable terminal 100. The display unit 130 may be, for example, a liquid crystal display.

The input unit 135 may be configured of a touch screen or one or more key buttons. The input unit 135 may serve as a medium for transmitting a user's instruction to the controller 150.

The memory unit 140 may be configured of, for example, a flash memory, a RAM, a ROM, or the like. The flash memory stores a real-time operating system (OS) and call processing software. Variables and states of these programs can be read and operated from RAM. In addition, the flash memory is a non-volatile memory that has a high processing speed and data is preserved, and new software is stored in this part when upgrading the software of the mobile communication terminal 100. The ROM may be configured as an EEPROM, store nonvolatile data, and perform input / output under the control of the controller 150. The ROM may store NAM (Number Assignment Module) parameters, other storage data (for example, a phone number, a name, a text message, an application program, application data, etc.) that can be used semi-permanently without being erased.

The interface unit 145 is a mobile communication terminal 100 is coupled to the external input and output device 160 via a wired or wireless, arbitrary data (for example, a control command input from the external input and output device 160, an external input and output device) Sound data transmitted to the user 160). When the external input / output device 160 and the mobile communication terminal 100 are connected by wire, the interface unit 145 is configured to transmit and receive data through a wire, and the external input / output device 160 and the mobile communication terminal 100 When connected wirelessly (for example, IrDA, Bluetooth, etc.), the interface unit 145 is configured to transmit and receive data via wireless. For example, the external input / output device 160 may be an earphone equipped with a remote controller, a wireless headset, or the like.

The controller 150 may allow the mobile communication terminal 100 according to the present invention to set a plurality of applications simultaneously with different operating modes (ie, a foreground mode and a background mode operation mode to two or more). The antenna unit 110, the wireless circuit unit 115, the audio processing unit 120, the handset 125, the display unit 130, the input unit 135, the memory unit 140, The interface unit 145 is controlled.

The detailed configuration of the controller 150 is illustrated in FIG. 2.

Referring to FIG. 2, the controller 150 may include an operation state controller 210, an input controller 220, an application management controller 230, a mode controller 240, and a screen controller 250.

The operation state controller 210 may include other components included in the controller 150, an antenna unit 110, a wireless circuit unit 115, an audio processor 120, a handset 125, a display unit 130, and an input unit ( 135) an operation state of the memory unit 140 and the interface unit 145. The operation state control unit 210 causes the phone call function to be performed in a new operation mode or a plurality of operation modes (or applications) when a call is received while the applications are operated in one or more operation modes by the mode control unit 240. The low priority application may be terminated and the telephone call function may be performed.

The operation state controller 210 may recognize whether the external input / output device 160 is coupled to the external input / output device 160 by wire or wirelessly. The operation state control unit 210 may recognize whether it is coupled with the external input / output device 160 through, for example, a change characteristic of a voltage level, and various methods recognized by those skilled in the art may be further used. It is self-evident.

The input control unit 220 controls commands of the external input / output device 160 via the interface unit 145 (for example, initiation of a telephone call when a call is received, reproduction of audio data, reproduction stop, pause, etc.) and / or The control command (for example, call request, data input, etc.) input from the input unit 135 is received and transmitted to the operation state control unit 210 or the mode control unit 240.

The input controller 220 determines whether the input control command is input from the input unit 135 or the external input / output device 160, generates command data of a predetermined format, and transmits the command data to the mode controller 240. For example, the control command input from the input unit 135 is for controlling an application operated in the foreground mode, and a control command input from the external input / output device 160 (here, a telephone call start command, etc.) may be excluded. ) Is for control of an application operating in the background mode, and may be preset. However, even when a control command is input from an external input / output device (for example, a wireless headset or an earphone with a remote controller), if the application operated in the foreground mode is for playing an audio file, the control of the corresponding application may be set. It may be. For each application driven in the foreground mode and the background mode, an operation mode of each application may be changed by input of a mode switch key provided in the input unit 135 or the external input / output device 160.

Of course, the signal input from the input unit 135 and the external input / output device 160 may be a key input signal or a voltage change amount, and the information generated by the input control unit 220 may be an operation start command or a control command of an application. have. However, in the present specification, for convenience of understanding, the signals received from the input unit 135 and the external input / output device 160 are control commands and the information output from the input control unit 220 is described as command data.

For example, the input control unit 220 may recognize the control command from where the control command is input. For example, the input control unit 220 may recognize the control command through a change characteristic of a voltage level. Self-explanatory The command data includes destination information indicating whether the control command is for the foreground mode or the background mode, or the mode control unit 240 corresponding to the destination information is input by the input control unit 220 or the operation state control unit 210. Command data).

The application management controller 230 performs management of each application stored in the memory unit 140, initial driving of an application corresponding to the command data by the input controller 220, and the like. The application management controller 230 may limit the plurality of applications in which the audio processor 120 is used to not be driven. This is difficult to accurately output sound data when sound data processed by a plurality of applications is reproduced through one audio processor 120 and a sound output unit (that is, the handset 125 or the external input / output device 160). Because. Of course, the plurality of applications can be executed simultaneously, but the operation state controller 210 controls only the sound data processed by the application controlled by the foreground controller 260 to be output through the output unit or by the background controller 270. Obviously, the volume of sound data processed by the controlled application can be automatically reduced.

The mode controller 240 controls the execution of an application driven in the foreground mode (that is, the operation mode of the application in which the driving state is displayed in the main form through the display unit 130) and the background mode ( That is, the display unit 130 may include a background controller 270 that controls the execution of an application driven in the operation mode of the application in which the driving state is not displayed or is displayed only as an icon. When the operation mode of the application is changed by the input of the mode switch key, the application controlled by each mode controller 240 may be changed.

Each mode controller 240, that is, the foreground controller 260 and the background controller 270, receives command data received from the input controller 220 or the operation state controller 210, and executes an application running in the corresponding mode. To control. Applications controlled by the mode controller 240 may be different or the same application.

An operation process of the mode controller 240 may be easily understood through the description with reference to the accompanying drawings.

The screen controller 250 controls the display 130 to display an operation state of the application by each mode controller 240, an operation state corresponding to a control command, and the like.

3 is a flowchart illustrating a plurality of application driving methods according to an exemplary embodiment of the present invention, and FIG. 4 is an exemplary diagram of a user interface screen illustrating a plurality of application driving processes according to an exemplary embodiment of the present invention.

Each step illustrated in FIG. 3 may be performed separately by each of the above-described components, but for convenience of description, the steps described in the mobile communication terminal 100 will be collectively described. Although collectively described as being performed in the mobile communication terminal 100, those skilled in the art will be able to easily understand the performing subject of each step.

Referring to FIG. 3, in step 310, the mobile communication terminal 100 drives a first application corresponding to a control command input from the input unit 135 or the external input / output device 160. The driven first application may be operated in the foreground mode. In the present specification, the foreground mode refers to the application of the corresponding application through the display unit 130 when a specific application (for example, playing an MP3 file, writing a message, playing a game, or a wireless Internet connection) is executed as in a normal mobile communication terminal. The operation mode in which the operation type is displayed. As shown in FIG. 4, when the user selects the MP3 file playback function while the original base screen is displayed, the screen 420 for playing the MP3 file is displayed on the display 130. The present invention eliminates the need to mount a separate processor chip on the motherboard because MP3 file playback is possible by the execution of the application.

In operation 315, the mobile communication terminal 100 determines whether a mode switch command for operating an application currently operating in the foreground mode from the input unit 135 or the external input / output device 160 in the background mode is input. do. In the present specification, the background mode is an operation mode in which the operation state of the corresponding application is not displayed or displayed in a minimized form (for example, an icon) through the display unit 130, but the operation of the application is continued. For example, even if the MP3 playback function is performed by switching from the foreground mode to the background mode, playback of the song that the user selects and plays in the foreground mode will be continued, and the sound by the playback is performed by the handset 125 or the like. The output will continue through the external input / output device 160.

The user may input a mode switch command by using the mode switch key (see 415 of FIG. 4). Depending on the number of times the mode switch key is input, the application mode may be switched in order of background mode, foreground mode, and background mode.

When the mode change command is not input, the mobile communication terminal 100 maintains the corresponding application to be driven in the foreground mode.

However, when a mode switch command is input, the mobile communication terminal 100 in operation 320 changes the operation mode to run in the background mode and then executes in the changed background mode. When the operation mode of the application is changed by the user's mode switching command, the display unit 130 is changed to a standby screen 425 indicating that an application is running in the background mode. In addition, even when the standby screen 425 is changed to an operation screen of another application, the display unit 130 may also display an icon 422 to facilitate recognition of the user. The icon 422 may be displayed corresponding to the application operated in the background mode. Here, it is obvious that the standby screen 425 and the icon 422 may be variously changed according to a user interface screen design method.

In operation 335, the mobile communication terminal 100 determines whether a control command for driving the second application is input from the input unit 135 or the external input / output device 160.

If no control command is entered, the flow proceeds to step 325 again. However, if a control command has been entered, the process proceeds to step 340 where the second application corresponding to the control command is executed in the foreground mode. That is, it is obvious that the first application and the second application which are executed at the same time are independent applications, and a process of newly creating one application for the simultaneous execution thereof is unnecessary. Screen 430 of FIG. 4 illustrates a screen display when a game is performed as a second application, and screen 435 illustrates a screen display when a wireless internet access function is performed.

In operation 345, the mobile communication terminal 100 determines whether an arbitrary control command is input from the input unit 135 or the external input / output device 160. The control command may include a mode switch command using a mode switch key, an execution state control command of an arbitrary application, and the like.

If no control command has been entered, wait at step 345. However, if a control command is input, the flow proceeds to step 350 to perform an operation corresponding to the control command. For example, if the control command is a mode change command, it will switch the operation mode of each application. In addition, if the control command through the input unit 135 controls the foreground mode, and the external input / output device 160 is set to control the background mode, the control command is controlled by the foreground control unit according to where the control command is input. It will be determined whether to deliver to 260 or the background controller 270, and a corresponding operation will be performed according to the control command.

As described above, when a plurality of applications are simultaneously driven and each application uses a sound output unit for effect sound output (for example, a game) or audio data playback (for example, for playing an MP3 file), etc. You will not be able to hear the sound normally. In this case, inconvenience of the user can be minimized by setting a priority to use the audio processor 120 between each application in advance. For example, if audio data reproduction has a high priority, only the reproduction sound of the audio data will be output through the sound output unit, and the output of the effect sound according to the game performance will be suppressed.

Of course, when a plurality of applications that need to use the audio processor 120 at the same time are selected, the driving of a later application is restricted or only sound data output by an application operated in the foreground mode is output through the sound output unit. It can also be set in advance.

Obviously, the various setting methods described above may be preset as defaults or individually selected by a user.

5 is a flowchart illustrating a method of driving a plurality of applications according to another exemplary embodiment of the present invention.

The embodiment described with reference to FIG. 4 has been described based on the case where the first and second applications are different from each other. However, in the plurality of application driving methods according to the present invention, the same application may be simultaneously executed in different operation modes. For example, when the first and second applications are both applications for playing DMB broadcasting, the user specifies that the first application driven in the foreground mode plays the KBS channel, and the second application driven in the background mode. You can also specify to play this MBC channel. In this state, the user can alternately watch broadcast signals of a plurality of channels by operating only the mode switching key.

As illustrated in FIG. 5, the mobile communication terminal 100 determines whether the applications operating in the plurality of operation modes are the same application and all use the audio processor 120 in operation 510.

If not the same application or if only one application is set to use the audio processor 120 (for example, one application is playing and the other application is in a standby state such as mode setting), the processing is performed as in FIG. 4. do.

However, if all of the same application and the audio processor 120 is used, the process proceeds to step 520 so that only the output sound of the application operated in the foreground mode is output through the sound output unit. Of course, as described above, the sound selection and control method to be output can be variously implemented.

In addition, if both the first and second applications are running the SMS application, the received message is displayed in the foreground mode, the text contents of the displayed message are copied, and the mode switching key is input to standby in the background mode. The message creation screen being displayed can be displayed in the foreground mode, and the message creation screen can be easily pasted by pasting the displayed message creation screen.

6 is a flowchart illustrating a processing method when an audio reproduction application and a telephone call function are simultaneously executed according to another preferred embodiment of the present invention.

In general, the mobile communication terminal 100 further includes various applications for performing each additional function in addition to the telephone call function. However, even in the multi-functionalized mobile communication terminal 100, since the most fundamental function is a phone call function, the phone call function needs to be processed first.

However, if the application already running does not use the audio processor 120, control of the audio processor 120 or the mode controller 240 may be unnecessary even if the telephone call function is executed later. This is because it is sufficient to control the currently running application to run in the background mode and then make a phone call in the foreground mode. The user can select the mode switch key after the telephone call is terminated so that the previously running application can be started again in the foreground mode.

However, if the currently running application (eg, playing an audio file) is using the audio processor 120, control of the application will be required for a phone call. This will be described in detail.

Referring to FIG. 6, in operation 610, the mobile communication terminal 100 executes an application for playing an audio file in response to a control command from the input unit 135 or the external input / output device 160. The executed application will be operated in the foreground mode, and the operation mode to the background mode will be switched by the user's input of the mode switch key.

In step 615, the mobile communication terminal 100 determines whether a call is received for a phone call.

If the call is not received, the operation according to the execution and control command of the application (for example, selecting and adding audio data to play) for playing the audio file is performed.

However, if the call is received, the flow proceeds to step 620 to perform a call function according to a predetermined condition.

That is, if an application for playing an audio file is running in the foreground mode, the mode is switched so that the corresponding application is operated in the background mode for displaying the caller, and the predetermined sound output condition for the bell sound output according to the call reception. Control audio file playback. The sound output condition is a first condition for maintaining the audio file playing state, a second condition for reducing the volume for playing the audio file to a predetermined size or less, a third condition for setting the volume for playing the audio file to 0, the audio file It may be any one of a fourth condition for pausing playback until the end of the call. Sound output conditions may be set by default or set by a user.

After the ring tone is output, a telephone call will be initiated by a user's call initiation command (eg, opening a folder, etc.).

The application of the above-described sound output condition may be suspended until the call start command is input by the user if the notification mode at the time of incoming call is a vibration mode other than the bell sound output.

In step 625, the mobile communication terminal 100 determines whether the phone call initiated by the call initiation command is terminated or the call is rejected by the call rejection command (for example, closing the folder immediately after opening the folder).

If a phone call is in progress, the mobile communication terminal 100 maintains its current state until the phone call ends. If the sound output condition is, for example, the first condition or the second condition described above, the output sound output through the handset 125 may be transmitted together with the user's voice to the sender's terminal.

If the telephone call is terminated or rejected, the mobile communication terminal 100 returns to the audio file playing condition (for example, volume setting) in step 610 to continue or continue playing the audio file.

The drawings and detailed description of the invention are merely exemplary of the invention, which are used for the purpose of illustrating the invention only and are not intended to limit the scope of the invention as defined in the claims or in the claims.

Therefore, those skilled in the art will understand that various modifications and equivalent other embodiments are possible from this. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

As described above, the present invention has the effect that a plurality of applications can be driven at the same time in a separate working mode to maximize user convenience.

In addition, the present invention has the effect that does not cause interruption of the user's work by continuously running in another mode without terminating the driven application when a call incoming or a message is received during the application execution.

In addition, the present invention has the effect that it is not necessary to create a separate integrated application or modify the conventional applications by integrating the applications for the simultaneous operation by plural operation modes of the application.

In addition, the present invention has the effect that it is possible to simultaneously perform a plurality of applications that can control the individual operation of the application operating in each of the plurality of modes.
