Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

When the battery 191 is detachably attached to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

The mobile terminal 100 may be provided with an accessory that protects the appearance or supports or expands the function of the mobile terminal 100. [ One example of such an accessory is a cover or pouch that covers or accommodates at least one side of the mobile terminal 100. [ The cover or pouch may be configured to interlock with the display unit 151 to expand the function of the mobile terminal 100. Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

The control unit 180 of the mobile terminal 100 according to an embodiment of the present invention may control the display unit 151 according to the detection result of the proximity sensor 141 when a call is connected according to a call reception or a call, (Off). For example, when a call is connected, the controller 180 controls the user's ear or the body part of the user such as the cheek of the user to contact the display unit 151 or a predetermined distance from the front of the display unit 151 The display unit 151 can be turned off.

This is because, when a user makes a call without making a call using a speaker phone or an earphone, the user can not confirm the screen of the display unit 151 and accordingly displays the image information on the display unit 151 It is not necessary. Accordingly, in order to save the limited power, the controller 180 may turn off the display unit 151 when the user is in a busy state. When the user separates the display unit 151 of the mobile terminal 100 from the body part of the contacted user, the controller 180 controls the display unit 151 And display keys on the display unit 151 that allow the user to select various functions related to the call, such as a recording function, a dial function, or a call termination function.

FIGS. 2A to 2D illustrate examples of screens displayed when the user selects termination of a call in the mobile terminal 100 related to the present invention in such a case.

Referring first to FIG. 2A, FIG. 2A illustrates a state in which a user places a mobile terminal 100 in his / her ear while talking. In this case, the user's body example is detected within a certain distance from the front surface of the display unit 151 or contacted to the front surface of the display unit 151. In this case, the proximity sensor 141 may detect the proximity sensor, and the control unit 180 may turn off the power of the display unit 151 based on the detection result of the proximity sensor 141.

In this state, when the user moves the mobile terminal 100 away from the mobile terminal 100 in order to terminate the currently connected call, the controller 180 turns on the display unit 151 and displays the call end key 200, May be displayed on the display unit 151. [0052] As shown in FIG. 2B, when the user selects the call termination key 200, the controller 180 can determine whether the called party is currently in a conversation state. Here, the status of the conversation partner may be referred to as a state in which the conversation partner continues conversation, that is, a state in which the conversation partner is inputting a sound signal including a speech signal to the transmitter of the communication partner terminal .

For example, when the call termination key 200 is selected, the control unit 180 determines whether or not there is an acoustic signal output through the receiver of the mobile terminal 100 It is possible to determine whether the call termination key 200 is selected. The control unit 180 preferably controls the operation of the display unit 151 until the front end of the display unit 151 is separated from the user's body by a predetermined distance or more and the call end key 200 is selected, It is possible to determine whether the call termination key 200 is selected in a state in which the calling party is in a conversation state depending on whether there is a signal.

In this case, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention can notify the user that there is an acoustic signal input from the calling party using various methods, that is, Can be displayed. For example, the control unit 180 may display image information such as a preset message on the display unit 151, or may display the image information using predetermined alarms, vibrations, or a bell sound or LED light emission.

The messages 210 and 250 shown in Figures 2c and 2d show these examples.

2C, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention, when the user selects the call end key, if there is an acoustic signal output through the receiver, (210). The user can again select whether to terminate the current connection from the user through the message 210. For example, if the user selects the termination of the call (in the case of selecting 'YES (212)' in FIG. 2C), the control unit 180 may terminate the currently connected call. However, if the user does not select termination of the call (in the case of selecting 'No (214)' in FIG. 2C), the control unit 180 can maintain the currently connected call without ending.

Meanwhile, the mobile terminal 100 according to the embodiment of the present invention can display to the user whether or not there is an acoustic signal received from the calling party even when the call is terminated. Figure 2d shows this example.

Referring to FIG. 2D, when the call is terminated, the controller 180 may display a message 250 informing the user that the call is terminated during the conversation. The alarm message 250 may be displayed in the form of a pop-up window or the like.

On the other hand, if there is an audio signal output through the receiver at the time of ending the call, the control unit 180 may determine that the call is terminated while the call counterpart is in conversation. More preferably, the control unit 180 determines whether the sound signal output through the receiver from the time when the front end of the display unit 151 is separated from the user's body by a predetermined distance or more until the call end key 200 is selected , It may be determined that the call is terminated while the call partner is in conversation.

Meanwhile, as shown in FIG. 2D, the controller 180 may perform various functions related to the message 250 displayed after the call is terminated. For example, when the first graphic object 252 included in the message 250 is selected, the control unit 180 may transmit a call to the calling party who has input the sound signal before the call ends. Alternatively, when the second graphic object 254 included in the message 250 is selected, the control unit 180 may perform a function of transmitting a message to the calling party that has input the sound signal before the end of the call. Alternatively, the control unit 180 may stop displaying the message 250 (when the third graphic object 256 is selected) according to the user's selection.

On the other hand, in the above description, a message indicating that the terminated call has been terminated during the conversation is displayed immediately after the termination of the call, but the present invention is not limited thereto. That is, the mobile terminal 100 according to the embodiment of the present invention can be used not only at the end of a call but at a time point selected by the user, among a plurality of calls made during a predetermined period, Messages may be displayed on the display unit 151 as a matter of course.

In this case, each time the call is terminated, the control unit 180 checks whether or not the call is terminated during the conversation and generates and stores a message related to the call. The control unit 180 may display the stored messages on the display unit 151 according to a user's selection. The messages displayed on the display unit 151 include a function of receiving a call or transmitting a message to the other party of the call, such as the messages 210 and 510 shown in FIG. 2C or 2D Of course.

Meanwhile, when the end of the call is selected, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention determines whether the signal received from the terminal of the other party is a voice signal inputted by the calling party or a simple noise It can be judged whether or not. The control unit 180 may determine that the call termination is selected in a state in which the calling party is in conversation only when the calling party inputs a voice signal.

For example, the control unit 180 may check the volume of the sound signal output from the receiver. The control unit 180 can determine that the communication partner is in a conversation state only when the sound signal output from the receiver is output at a volume higher than a predetermined level. That is, when a noise such as an automobile horn received through the terminal of the communication partner or a speech of other persons around the communication partner is received from the vicinity of the communication partner, the controller 180 outputs the received noise to the receiver If the level of the volume is below a predetermined level, it can be determined that the call termination is selected or the call terminated when the calling party is not in conversation.

Alternatively, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention may recognize a sound signal output from the receiver by using a voice recognition function. For example, when the end of the call is selected by the user, the control unit 180 can determine whether the sound signal output through the receiver is recognizable by voice. The control unit 180 may determine that the call termination is selected or terminated in a state where the calling party is in conversation only when the sound signal output from the receiver can be recognized as a voice.

In this case, the speech recognition function may be implemented as a STT (Speech To Text) function. That is, when the call termination is selected by the user, the control unit 180 can determine whether the sound signal output through the receiver can be recognized as text using the STT function. If it is recognizable as text, the control unit 180 may determine that the call termination is selected or terminated in a state where the calling party is in conversation. In this case, the control unit 180 displays the text recognized as a result of the STT function as a message 210 indicating that the calling party is in conversation or a message 210 indicating that the calling party has ended the conversation during the conversation (250).

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal 100 configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

3 is a flowchart illustrating an operation procedure when a call termination key is selected in a mobile terminal related to the present invention.

Referring to FIG. 3, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention performs a call connection according to the incoming call or the originated call (S300). While the call of step S300 is being connected, the controller 180 may determine whether the call termination is selected (S302). If the call is not terminated in step S302, the controller 180 maintains the current state, that is, the state in which the call is connected, and then proceeds to step S302 to determine whether the termination of the call is selected.

In operation S302, the call termination key 200 is selected when the user's body is separated from the display unit 151 by a predetermined distance. That is, even if a user's body such as a cheek or an ear is separated from the display unit 151 by a predetermined distance, if the preset key, that is, the call end key is not selected by the user, It may not be determined in step S302 that the call has ended.

On the other hand, even if the user's body is not separated from the display unit 151 by a predetermined distance in step S302, if the predetermined key (for example, 'power key') is directly inputted from the user for termination of the call , The controller 180 can determine that the call is terminated. In this case, the control unit 180 may determine that the user has selected to immediately terminate the currently connected call. If the call is terminated immediately by the user, the control unit 180 determines that the sound input from the calling party Even if there is a signal, it may not be displayed to the user.

However, after the user's body is separated from the display unit 151 by a predetermined distance or more, the display unit 151 is turned on according to the distance, and as shown in FIG. 2, If the call termination key 200 among the call related keys is selected by the user, the controller 180 may determine that the call is terminated in step S302.

If it is determined in step S302 that the call is terminated, the controller 180 may determine whether the called party is in a conversation state when the call termination is selected (S304). For example, in step S304, the control unit 180 may determine whether the calling party is in a conversation state based on whether a sound signal is output from the receiver when the user selects termination of the call. More preferably, the control unit 180 determines whether the sound signal output to the receiver is a sound signal for a predetermined time after the user's body is separated from the display unit 151 by a predetermined distance or more, Whether or not the other party is currently in a conversation state.

If it is determined in step S304 that there is an audio signal output through the receiver when the call termination is selected, the control unit 180 determines whether the call is being received while the other party of the currently connected call is receiving a sound signal It can be judged that it is finished. In step S306, the control unit 180 may display a state in which the other party is in conversation using a preset method, i.e., an alarm, vibration, LED light source, or predetermined image information.

On the other hand, if the user indicates to the user that the other party is in conversation, the control unit 180 can again confirm whether or not to end the call from the user (S308). If it is determined in step S308 that the user selects the termination of the currently connected call even in a state in which the calling party is currently in conversation in step S306, the controller 180 may terminate the currently connected call S310). However, if it is determined in step S308 that the user does not reselect the call termination or does not select terminate the call within a predetermined time period (in the case of selecting 'No' 214 in FIG. 2) The currently connected call state can be maintained (S312). In this case, the control unit 180 may proceed to step S312 again, and may determine again whether the end of the currently connected call is selected from the user in step S302.

Meanwhile, in the mobile terminal 100 according to the embodiment of the present invention, it is possible to more accurately determine whether or not the communication partner is in a conversation state by using various methods in step S304. For example, in step S304, the control unit 180 may determine whether the communication partner is in conversation, based on whether the sound signal output from the receiver is greater than a preset volume or is recognizable by voice.

4A and 4B illustrate a case where the mobile terminal 100 related to the present invention determines whether or not there is an acoustic signal to be output to the receiver based on the volume of the received signal or the recognized voice signal FIG.

4A shows an example of an operation procedure for determining whether the called party is in conversation according to the volume of the sound signal output from the receiver.

Referring to FIG. 4A, the controller 180 of the mobile terminal 100 according to the embodiment of the present invention can measure the volume level of the outputted sound signal when there is an acoustic signal output through the receiver S400). In step S400, it is determined whether the sound signal output from the receiver is input by the current communication party or due to noise only in the vicinity of the communication party, depending on whether the volume level measured in step S400 is equal to or greater than a preset level can do.

That is, if it is determined in step S400 that the sound signal output from the receiver is equal to or higher than a preset volume level, the controller 180 may determine that the sound signal is input from the calling party, It can be determined that the current conversation is in progress (S404). In this case, the controller 180 proceeds to step S306 of FIG. 3 to display the message to the user by using at least one of the message, vibration, LED optical signal, alarm, and sound signal .

However, if it is determined in step S400 that the sound signal output from the receiver is below a preset volume level, the controller 180 may determine that the sound signal is due to noise, (S406). In this case, the controller 180 proceeds to step S310 of FIG. 3 and terminates the currently connected call according to the user selection in step S302.

Meanwhile, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention may determine whether or not the other party is in conversation by various methods other than the method of checking the volume level. For example, the control unit 180 may use a voice recognition function or the like.

FIG. 4B illustrates an operation of the mobile terminal 100 according to an embodiment of the present invention.

Referring to FIG. 4B, if there is an acoustic signal output through the receiver, the controller 180 may determine whether the acoustic signal can be recognized as speech (S450). If it is determined in step S400 that the sound signal output from the receiver can be recognized as a sound, it can be determined that the sound signal is input from the communication partner. Then, the control unit 180 can determine that the calling party is currently in a conversation (S452). In this case, the controller 180 may proceed to step S306 of FIG. 3 to display to the user that the conversation partner is currently in conversation using a message, a vibration, a light source of the LED, an alarm, or the like.

If it is determined in operation S450 that the sound signal output through the receiver can be recognized as a sound, the controller 180 may recognize the sound signal as a sound signal and display a result of converting the sound signal into text. The speech signal converted into text by the STT (Speech To Text) function can be displayed on the display unit 151. More preferably, a message for notifying that the called party is currently in conversation in step S306 (E.g., message 210 in FIG. 2).

However, if it is determined in step S450 that the sound signal output from the receiver can not be recognized as a sound, the control unit 180 may determine that the sound signal is due to noise only, It can be determined that the user is not in conversation (S454). In this case, the controller 180 proceeds to step S310 of FIG. 3 and terminates the currently connected call according to the user selection in step S302.

4A and 4B, it is explained that the communication party is in conversation using the volume level of the sound signal output from the receiver or whether the sound signal is recognizable by voice. However, But the present invention is not limited thereto. In other words, it is needless to say that other methods other than the above methods may be used.

That is, when the volume of the sound signal output from the receiver is equal to or greater than a predetermined level, the controller 180 determines whether the sound signal can be recognized as a voice signal, and determines whether or not the calling party is in conversation You can judge. Alternatively, when the sound signal can be recognized as a sound signal, it may be determined whether or not the other party is in conversation depending on whether the volume of the sound signal is equal to or higher than a predetermined level.

5A to 5D show an example in which a call connection is maintained according to a user's selection when a call termination key is selected in the mobile terminal 100 according to the present invention.

5A, when the user selects the call termination key 200 for termination of the call, the mobile terminal 100 is in a state where the mobile terminal 100 is separated from the user's body by a predetermined distance, that is, It may be the case that the call termination key 200 displayed on the display unit 151 is selected in a state in which the mobile terminal 100 is spaced apart from the ear or cheek of the user by a predetermined distance for termination.

In this case, the controller 180 of the mobile terminal 100 according to the embodiment of the present invention can determine whether or not the current communication party is in a conversation state. And may display a message 210 or 510 as shown in Figures 5b and 5c, depending on the result. For example, if the calling party is in a conversation, the controller 180 may display a message 210 on the display unit 151 as shown in FIG. In this case, as shown in FIG. 5B, the message 210 may include a message indicating that the calling party is currently in a conversation state and a message indicating that the user has terminated the currently connected call (when selecting 'Yes' in FIG. 5B) And graphical objects 212 and 214 that may be selected to maintain the connection state of the call (if 'No' is selected in FIG. 5B).

On the other hand, in the case of the message 210 shown in FIG. 5B, when the call end key 200 is selected from the user, it may be displayed depending on whether there is an acoustic signal output through the receiver. More preferably, when the call termination key 200 is input from a time when a user's body is separated from a front face of the display unit 151 by a predetermined time or longer, the control unit 180 transmits the message 210 to the display unit 151. [ Can be displayed on the display unit 151 as shown in FIG. 5B) or the end of the currently connected call (in the case of selecting 'YES' 212 in FIG. 5B), as shown in FIG. 5B. FIG. 5D shows an example of a case where the user has selected to keep the currently connected call (if 'NO (214)' is selected in FIG. 5B).

4A and / or 4B, the control unit 180 controls the volume level of the sound signal output through the receiver and / or the volume level of the sound signal output through the receiver, It may be determined whether or not the call is terminated while the other party of the call is in a conversation based on a result of the determination based on whether or not the sound signal is recognizable as a voice signal. If the sound signal output from the receiver can be recognized as a sound, the controller 180 converts the sound signal recognized as the sound into a text form, and outputs the converted result to the control unit 180, It may be displayed in a message for informing the user. FIG. 5C shows an example of a message 510 including the result of converting the recognized speech into text.

Referring to FIG. 5C, the message 510 includes a result 500 converted into the sound signal text input from the other party. In this case, the user can know the content of the voice signal input by the calling party through the message 510, and can select whether to terminate the currently connected call. Here, the content of the voice signal inputted by the calling party is preferably transmitted to the mobile terminal 100 until the user selects the call termination key 200 after the mobile terminal 100 is separated from the user's body, for example, May be a voice signal input from the calling party for a period of time.

On the other hand, as shown in FIG. 5C, when the voice content of the calling party is displayed in the form of text, the user can determine whether the calling party desires more conversation based on the text content. For example, if the voice signal input by the calling party is a simple greeting such as "goodbye " at the time when the user enters the call end key 200, It may be recognized that there is no need to connect the call anymore. However, as shown in FIG. 5C, if the voice signal input by the calling party at the time when the user inputs the call end key 200 is " Based on the contents, it is possible to recognize that the calling party has more content to call.

In this case, as shown in FIG. 5C, the user may not select the termination of the call (in the case of selecting 'No 504' in FIG. 5C). The control unit 180 may maintain the currently connected call. Figure 5d shows this example. That is, when the call connection state is maintained by the user through the message 210 or 510, as shown in FIG. 5D, the control unit 180 determines whether the user has selected the call termination key 200 . In this case, the control unit 180 may output the sound signal received from the calling party as a speaker phone state. If the user's body (e. G., Ear) is detected within a certain distance from the front of the display unit 151, that is, when the user brings the mobile terminal 100 to his / 2a), the control unit 180 may output the sound signal received from the calling party through the receiver. In this case, it goes without saying that the control unit 180 may turn off the display unit 151.

However, if the user selects 'Yes (502)' in FIG. 5C, the controller 180 may terminate the currently connected call according to the user's selection.

Meanwhile, according to the above description, the mobile terminal 100 according to the embodiment of the present invention may indicate that the call is displayed to the user when the call is terminated while the other party is in conversation, There is one.

6 is a flowchart illustrating an operation procedure of the mobile terminal according to the present invention.

Referring to FIG. 6, the control unit 180 of the mobile terminal 100 according to the embodiment of the present invention may terminate the currently connected call according to the user's selection (S600). Then, it is determined whether the terminated call is terminated while the other party is in conversation (S602).

For example, when the preset key (call end key 200) is input to terminate the currently connected call in step S602, the control unit 180 determines that the sound signal outputted from the receiver of the mobile terminal 100 It is possible to determine whether the call is terminated while the caller is in a conversation state. In this case, the control unit 180 may use the volume level of the sound signal output from the receiver or whether the sound signal can be recognized as a voice, as described above with reference to FIGS. 4A and 4B, for more precise determination. Or the volume level of the sound signal and whether or not the sound signal can be recognized by voice, in a predetermined order.

On the other hand, the control unit 180 may determine whether the communication partner is in a conversation state according to whether there is an acoustic signal output to the receiver during a predetermined time period. For example, the control unit 180 can determine whether there is an acoustic signal output from the receiver before or after a predetermined time based on a point in time when the call end key 200 is selected by the user, State or not. The control unit 180 determines whether the user's body (ear or cheek) is separated from the display unit 151 of the mobile terminal 100 by a predetermined distance or more, for example, During the time from when the call end key 200 is selected by the user, it may be determined whether or not the calling party is in a conversation state depending on whether there is an acoustic signal output through the receiver.

If it is determined in step S602 that the call is terminated while the other party is in conversation, the controller 180 may indicate to the user that the call is ended during the conversation (S604). For example, in step S604, the control unit 180 displays a message on the display unit 151 indicating that the call is terminated during the conversation, Optical signals, acoustic signals, or the like. Here, the message, vibration, alarm, optical signal, or sound signal may be output together.

In response to the display of step S604, the control unit 180 may transmit a call origination message or a message from the other party of the call according to the user's selection (S606). For example, the message displayed in step S604 may include at least one graphic object related to a function of allowing a user to place a call or send a message to a party of the call. In this case, the control unit 180 may send a call to the specific party, that is, the party of the call terminated during the conversation, or a message created by the user, based on the user's selection of the graphic object.

7A to 7D show an example of connecting a call or transmitting a message when a call is ended during a conversation in a mobile terminal 100 related to the present invention.

First, as shown in FIG. 7A, when the user selects the termination of the currently connected call, the control unit 180 may terminate the currently connected call. In this case, the control unit 180 may determine whether the other party of the terminated call has terminated the call during the conversation, as described in step S604 of FIG. As shown in FIG. 7B, according to the determination result, the user of the call can display a message 250 indicating that the call is ended during the conversation.

In this case, the message 250 may include graphic objects related to various functions. For example, as shown in FIG. 7B, the message 250 may include a first graphic object 252 related to a function of calling a caller of a corresponding call, and a function of transmitting a message to a party of the call And associated second graphic object 254. Or a third graphic object 256 that may stop displaying the message 250. [ In addition, if the sound signal output through the receiver at the end of the call can be recognized as voice, the result of converting the text into text may be further included in the message 250, as shown in FIG. 5C Of course.

In this state, when the user selects the first graphic object 252, the control unit 180 may issue a call to the other party of the call as shown in FIG. 7C. And, if the other party answers the originated call, the call can be connected accordingly.

On the other hand, when the user selects the second graphic object 254, the control unit 180 displays a screen 710 for creating a message to be transmitted to a counterpart of the corresponding call and an input method editor (IME) May be displayed on the display unit 151. [0064] In this case, the user can create a message as shown in FIG. 7D, and the recipient of the created message can be the other party of the call, that is, the other party of the call terminated during the conversation.

Meanwhile, according to the above description, the mobile terminal 100 according to the embodiment of the present invention is not limited to indicating that the other party whose conversation is ended immediately after the conversation ends is in conversation. That is, the mobile terminal 100 according to the embodiment of the present invention can confirm the calls that are terminated while the other party is in a conversation during a certain period of time according to the user's selection, It is of course possible to display information related to calls.

FIGS. 8A and 8B show an example in which messages related to calls terminated during a conversation are displayed during a predetermined period in the mobile terminal related to the present invention.

For example, as shown in FIG. 8A, the control unit 180 of the mobile terminal 100 according to an embodiment of the present invention displays information related to calls that are terminated while the calling party is in a conversation for a preset period of time A message 800 for receiving a selection from the user. In this state, if the user does not select the display of the information related to the calls terminated during the conversation (in the case of selecting 'No (804)' in FIG. 8A) The display of the display 800 can be terminated. In this case, the controller 180 may display the message 800 again after a predetermined time elapses.

On the other hand, when the user selects the display of the information related to the calls terminated during the conversation (in the case of selecting 'Yes (802)' in FIG. 8A), the control unit 180 transmits the information And may be displayed in the form of messages output on the display unit 151. That is, as shown in FIG. 8B, the control unit 180 can separately display messages 810, 812, and 814 corresponding to the respective currencies, which are determined to have been terminated during the conversation. As shown in FIG. 8B, the messages 810, 812, and 814 include a function of transmitting a call to the other party of the corresponding call, a function of transmitting a message, and a function of ending display of the corresponding message, respectively And may include at least one corresponding graphical object. Accordingly, the control unit 180 can select any one of the displayed messages 810, 812, and 814 from the user, send a call to the call destination corresponding to the selected message, or transmit a message created by the user .

On the other hand, in the above description, the case where the call termination is selected or after the termination of the call is detected, it is detected that the calling party is in conversation and the call is displayed. Therefore, when the call termination is performed while the calling party is in conversation, the mobile terminal 100 according to the embodiment of the present invention notifies the user of the pre- can do.

However, it is needless to say that the mobile terminal 100 according to the embodiment of the present invention may indicate that the call is terminated in a state where the calling party is in the conversation only in one of the cases according to the user's selection. That is, when the user sets a message indicating that the calling party is in conversation only before the call ends, the control unit 180 displays the message only before the call is terminated, The message may not be displayed. On the contrary, if the user sets a message indicating that the called party is in a conversation state only after the call is terminated, the controller 180 displays the message only after the call is terminated, It is possible to prevent the message from being displayed before the end of the message.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. The foregoing detailed description, therefore, should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
