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 uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. 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.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. 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 camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. 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.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

Also, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

In the stereoscopic display unit, a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system) can be applied.

2 is a flowchart illustrating a mobile communication system 200 according to an embodiment of the present invention.

The mobile communication system 200 includes first and second terminals 1100 and 1200 that mutually transmit and receive signals according to a call connection. The first and second terminals 1100 and 1200 include at least one of the components described in FIGS. 1A through 1C.

When a multi-party call is performed, more terminals than the first and second terminals may be included in the mobile communication system 200. Hereinafter, embodiments of the present invention will be described by way of example in which a one-to-one call is made for convenience of explanation, but the present invention is not limited thereto and can be applied to a multi-party call.

When a call connection is established between the first and second terminals 1100 and 1200, the first and second terminals 1100 and 1200 mutually exchange signals according to the call (S210 and S220).

The first and second terminals 1100 and 1200 can perform voice, image, and data communication using a network (not shown) included in the mobile communication system 200, and can transmit and receive signals corresponding thereto. That is, the first and second terminals 1100 and 1200 denote electronic devices capable of transmitting and receiving various data via the network. When there is a call connection request from the counterpart terminal via the network, the first and second terminals 1100 and 1200 can perform a call with the counterpart terminal or request a call connection to the counterpart terminal.

A network connecting the first and second terminals 1100 and 1200 is included in the mobile communication system 200 and the network is capable of transmitting and receiving at least one of voice and image data according to the crossing specification for communication.

More specifically, the call connection may be implemented by a circuit-switching or packet-switching network scheme. Further, the call connection may be performed through a voice over internet protocol (VoIP), which provides voice service through a public switched telephone network (PSTN) network using Internet Protocol (IP) technology, Lt; RTI ID = 0.0 > VoLTE < / RTI > (voice over LTE).

For example, the first and second terminals 1100 and 1200 may transmit and receive the video and audio data using a network such as Ethernet or IEEE 802.3, or may transmit the data using a wireless network such as IEEE 802.11 Can send and receive

The call according to the call connection includes a voice call and a video call.

In the case of a voice call, the first and second terminals 1100 and 1200 transmit a signal applied to the microphone to the counterpart terminal, and output the signal transmitted from the counterpart terminal through the sound output section.

In the case of a video call, video data captured by a camera together with voice data applied to a microphone are simultaneously transmitted to a counterpart terminal, and voice data and video data transmitted from the counterpart terminal are output through an acoustical output unit and a touch screen, respectively . Since such a video call is implemented by video streaming technology, users can talk to each other while watching each other's images.

The first and second terminals 1100 and 1200 transmit information related to an event to a counterpart terminal through a communication channel when a call connection is established.

More specifically, the terminal detects that an event has occurred in at least one application, and transmits a notification message to the counterpart terminal connected to the call through the network to inform that the event has occurred.

The application is a concept including a widget, a home launcher, and the like, and refers to all types of programs that can be run on the terminal. Accordingly, the application may be a program that performs functions of recording, recording, a web browser, moving picture playback, message transmission / reception, schedule management, and application update.

The occurrence of the event may be caused, for example, in the case where recording / recording is started during a call, recording is stopped or paused during the call, there is a missed call, there is an application to be updated, Charging, terminal power on, power off, LCD awake key, alarm, incoming call, missed notification, etc. .

The present invention relates to a method for guiding or warning a user to record a call during a call of a partner terminal in performing a voice and / or image function, and the event is related to recording during a call or recording during a call. Hereinafter, for convenience of explanation, it is assumed that the first terminal 1100 starts recording during a call while a call is being made between the first and second terminals. However, the present invention is not limited thereto, It is also applicable to the case where recording or recording is performed.

When the first terminal 1100 starts recording during a call based on a user request (S212), the first terminal 1100 transmits a notification message to the second terminal 1200 via the network, (S214).

The recording during the call means recording the voice data transmitted from the terminal and the voice data received from the partner terminal and generating or mixing the corresponding recording files to generate one recording file.

Recording during the call may be performed by a function embedded in the telephone application or by a separate application associated with the telephone application and other recording.

The at least one file generated by the call recording may be stored in the memory of the terminal or may be transmitted to the predetermined server so as to be stored in a predetermined server.

Spyware can also be used to record on the phone. The terminal may monitor whether a recording is occurring during a call and whether a recording file is generated by recording during a call, in order to detect that recording is being performed during the call by the spyware. By monitoring, it is possible to detect that the recording was made during the call even after the end of the call connection. If the terminal detects that recording has been made during the call even after the call is terminated, the terminal transmits a notification message do.

In other words, the first terminal 1100 can notify the second terminal 1200 of the in-communication state even when the first terminal 1100 detects not only the recording during the conversation but also the recording of the conversation after the call connection is completed A notification message can be transmitted.

The notification message includes information related to recording during a call. For example, the information related to the recording during the call includes a start time at which recording is started during a call, a total recording time of recording during a call, a stop time at which recording of the call is stopped, a name of a recorded recording file, Or the like.

If the call connection is made using a wireless Internet network, the notification message may be transmitted through a data channel included in the network. Alternatively, if the call connection is made using a circuit switching network, the notification message may be transmitted to the second terminal 1200 (e.g., a short message service (SMS), a multimedia message service Lt; / RTI > If the notification message is transmitted after the call connection is terminated, the notification message may be transmitted to the second terminal 1200 in various manners.

If the notification message is transmitted to the second terminal 1200, the second terminal 1200 outputs guidance information for recording the call during the call (S222).

The second terminal 1200 outputs the guide information in at least one of a visual, auditory, and tactile manner.

The guide information is information for informing that the recording of the call is being performed in the counterpart terminal, and when the call connection is terminated, the guide information is recorded in the counterpart terminal Which is the information that leads to the loss. That is, the other terminal warns the user that the call content is being recorded or recorded.

In outputting the guide information, the terminal may vibrate the main body, output a warning sound or a voice warning message through the sound output unit, or output a visual message through the touch screen. Also, the above methods may be mixed and output.

For example, the terminal may include an audio output unit configured to output audio information included in a signal received from a counterpart terminal, and the terminal may control the audio output unit such that the audio information and the guide information are simultaneously output.

In another example, the terminal may include a touch screen configured to output information related to the counterpart terminal and the guide information as a call connection is established with the counterpart terminal.

The control method related to the present invention described above can be embodied in various forms as shown in FIGS. 3A to 10. Hereinafter, in the illustrated embodiment, the same or similar reference numerals are given to the same or similar components as those of the preceding example, and the description is replaced with the first explanation.

FIGS. 3A and 3B are exemplary diagrams for explaining the operation of the first and second terminals included in the mobile communication system of FIG.

Referring to FIG. 3A, a mobile communication system 200 according to the present invention includes first and second terminals 1100 and 1200. Although a bar type mobile terminal is shown as an example of the first and second terminals 1100 and 1200, the first and second terminals 1100 and 1200 are not limited thereto and may be modified into various types of mobile terminals or fixed terminals. .

For example, the first and second terminals 1100 and 1200 may be a tablet PC, a laptop, a personal computer (PC), a smart phone, a personal digital assistant (Personal Digital Assistant), a mobile communication terminal, a wearable device (e.g., a smartwatch, a glass-type terminal, or a head mounted display (HMD) Lt; / RTI >

As a call connection is established between the first and second terminals 1100 and 1200, signals corresponding to the call are transmitted and received and signals transmitted and received to the output sections of the first and second terminals 1100 and 1200 are output.

For example, referring to FIG. 3A, a voice call can be made between the first and second terminals 1100 and 1200.

Accordingly, voice data ('account number notification') input to the microphone of the first terminal 1100 can be output from the sound output unit of the second terminal 1200.

Further, the first and second terminals 1100 and 1200 have touch screens 1151 and 1251, respectively, and can output visual information related to the call using the touch screen. The time information associated with the call may include graphical objects related to execution of the additional function, information on the other party's terminal, total call time, and execution screen of the telephone application.

A graphical object 300 associated with the execution of the on-call recording function may be included in the execution image of the telephone application. When a touch is applied to the graphic object 300, the terminal may transmit a request message to the counterpart terminal to immediately start recording during a call or to obtain counterpart agreement on recording during a call. In the case of transmitting a request message, recording is carried out only when there is a partner agreement, and execution of recording during a call is restricted until the partner agreement is made.

When recording is performed during the call, information related to recording during the call is transmitted from the first terminal 1100 to the second terminal 1200. In other words, as the first terminal 1100 performs recording during a call, the second terminal 1200 receives information related to recording during the call using the wireless communication unit.

The second terminal 1200 controls the output unit to output guidance information for informing that the recording of the call is being performed in the counterpart terminal in response to the information related to the recording during the call.

For example, as shown in FIG. 3A, when vibration is generated or voice information ('give account number') and voice guidance information ('the other party is recording') included in the signal received from the counterpart terminal Outputting information related to the other party's terminal and visual guidance information ('the other party has started recording') on the display screen 1251, or simultaneously outputting the above-described outputs.

In this manner, since guide information for guiding the recording during the call is output in various ways, the user can recognize the fact that recording is being performed in the other terminal during the call.

According to the present example, the problem that the fundamental rights guaranteed by the Constitution are infringed can be solved because unauthorized recording occurs during the conversation.

On the other hand, the method of outputting the guide information can be set or reset by the user. For example, the user can set the output method of the guide information to output only the vibration, or set the guide information not to be output.

The second terminal 1200 can output the screen information formed to receive the user input for approving or rejecting the recording to at least one area of the touch screen have.

For example, as shown in FIG. 3A, a pop-up window 310 including graphic objects corresponding to 'confirmation', 'rejection', and 'recording' may be output to at least one area of the touch screen. The second terminal 1200 terminates the output of the guidance information when a touch is applied to the 'confirmation', terminates the voice call when the touch is applied to the 'rejection', or terminates the voice communication performed by the first terminal 1100 And transmits the end message to the first terminal 1100 so that the recording of the first terminal 1100 is forcibly terminated. When a touch is applied to the 'recording', the second terminal 1200 also starts recording during a call, and a recording file is generated accordingly.

Referring to FIG. 3B, a video call can be established between the first terminal 1100 having the first touch screen 1151 and the second terminal 1200 having the second touch screen 1251.

The first video 1116 captured by the first terminal 1100 and the second video 112 captured by the second terminal 1120 and transmitted to the first terminal 1100 are transmitted to the first terminal 1100 At least one of the display units 320 may be output to the touch screen 1151. Similarly, the second terminal 1200 may include a first image 330 captured by the first terminal 1100 and transmitted to the second terminal 1200, and a second image 336 captured by the second terminal 1120 At least one may be output to the touch screen 1251.

The execution screen according to the video call may include graphic objects related to the execution of the additional function, one of the graphic objects being related to the execution of the recording function of recording video call contents.

The recording function is to record voice and image data transmitted from a terminal and voice and image data received from a partner terminal, and generate or mix the corresponding recording files to generate a single recording file.

The first terminal 1100 may transmit a request message to the second terminal 1200 to immediately execute the recording function or request the execution of the recording function when a touch is applied to the graphic object 302 related to the execution of the recording function .

When the recording function during the call is executed, information related to the recording during the communication is transmitted from the first terminal 1100 to the second terminal 1200. In other words, as the first terminal 1100 performs recording during a call, the second terminal 1200 receives information (or a notification message) related to the recording during the call using the wireless communication unit.

In response to the information received from the first terminal 1100, the second terminal 1200 controls the output unit to output guidance information for informing that the on-call recording is being performed in the counterpart terminal.

For example, as shown in FIG. 3B, it is possible to generate vibration, to simultaneously output voice information and voice guidance information included in a signal received from a correspondent terminal, or to display on a display-on touch screen 1251, To output the information related to the other party's terminal and the visual guide information 340, or simultaneously output the above-described outputs.

On the other hand, in the case of on-the-call recording, a video including a part of the user's body may be generated in the counterpart terminal without user's consent and distributed to an unspecified number of users. In order to prevent such a problem in advance, the terminal according to the present invention restricts the image data captured by the camera to be transmitted to the first terminal 1100 when recording is performed during the communication in the other terminal.

More specifically, when the first terminal 1100 is in the middle of recording the voice and image data according to the video call to the first terminal 1100, the second terminal 1200 transmits the voice data to the first terminal 1100, 1 terminal 1100 but restricts the transmission of image data. Alternatively, the wireless communication unit may be controlled so that a predetermined alternative image is output instead of the image data captured by the camera. Accordingly, in the first terminal 1100, the output of the second image 320 photographed by the second terminal 1120 and transmitted to the first terminal 1100 is terminated, and the predetermined alternative image 322 is output .

The limitation of the video data transmission can be released only when there is user agreement of the second terminal 1200 for recording during the call. More specifically, when a notification message for informing of the recording is received from the first terminal 1100, the second terminal 1200 transmits screen information formed to receive user input for approving or rejecting the recording to at least one region .

For example, as shown in FIG. 3B, a pop-up window 340 including graphic objects corresponding to 'confirmation', 'rejection', and 'recording' may be output to at least one area of the touch screen. The second terminal 1200 resumes the transmission of the video data when the touch is applied to the 'confirmation', and terminates the video call when the touch is applied to the 'rejection' And transmits a termination message to the first terminal 1100 so that the middle recording is forcibly terminated. When a touch is applied to the 'recording', the second terminal 1200 also starts recording during a call, and a recording file corresponding thereto is generated.

4A and 4B are illustrations for explaining a method of visually outputting guidance information when recording is being made during a call in a counterpart terminal.

The terminal can output the guidance information in a visual manner when the other terminal is recording during communication. More specifically, detailed information related to recording during a call can be output to the touch screen based on information received from the counterpart terminal.

For example, as shown in FIG. 4A, the second terminal 1200 may determine, based on the information received from the first terminal 1100, a start time at which recording is started during a call, a total recording time of a recording during a call, and And may output at least one of the stop times (400) during which the recording during the call is stopped. At this time, the total talk time ('00: 34') and the total recording time ('00: 13 ') can be outputted at the same time, and the user can compare the recording time with the talk time.

4B, when the call recording is terminated, the second terminal 1200 transmits the information ('00: 34') indicating the recorded section along with the total talk time (' 00: 13-00: 30 ') as guide information.

Accordingly, the user can check detailed information related to recording of calls made or made in the other party's terminal.

5 is a flowchart illustrating a mobile communication system according to an embodiment of the present invention.

The mobile communication system includes a first terminal 1100 and a call announcement server 1300. A subscriber management server 1310, a push server 1320, and a second terminal 1200.

When the first terminal 1100 starts recording while the voice / video call is connected, the first terminal 1100 requests the recording announcement server 1300 during the call to announce the recording during the call. The second terminal 1200, which proceeds to a voice / video call, receives a push message corresponding to the recording announcement information during the call from the push server 1320. Here, the push message includes the telephone number information of the first terminal 1100 that started recording. The second terminal 1200 generates guide information for guiding the recording during the call based on the push message. The second terminal 1200 reflects the guide information to the telephone application to output the guide information.

When the first and second terminals 1100 and 1200 are connected to the call announcement server 1300, the first terminal 1100 and the second terminal 1100 start recording, And transmits the number to the second terminal 1200 through a message, the Internet, or the like.

The call announcement server 1300 transmits a subscriber information request message to the subscriber management server 1310. [ The call announcement server 1300 receives a subscriber information response message corresponding to the subscriber information request message from the subscriber management server 1310. [ In other words, the call announcement server 1300 is connected to the subscriber management server 1310 in order to check whether the other party of the first terminal 1100 that has transmitted the recorded information during the call is a terminal equipped with the phone application, Lt; / RTI > In addition, the call announcement server 1300 may check whether the first terminal 1100 and the second terminal 1200, which have transmitted the recorded information during the call, The subscriber management server 1310 may transmit a subscriber information request message to the subscriber management server 1310 to confirm whether the terminal is a subscriber to the communication company. The call notification server 1300 receives a subscriber information response message from the subscriber management server 1310 and transmits a push request message to the push server 1320. [

The push server 1320 refers to a server that transmits a push message to at least one of the first and second terminals 1100 and 1200 and the call announcement server 1300. [ The push server 1320 receives the push request message from the call announcement server 1300. The push server 1320 may be implemented as an AOM (Always On Management) server as a smart push server. The push server 1320 confirms the terminal identification information included in the push request message and transmits the push message to the terminal (e.g., the second terminal) corresponding to the terminal identification information. At this time, the push message includes a notification message informing the call recording and the telephone number of the first terminal 1100.

When the first and second terminals 1100 and 1200 transition to a call recording state while a voice / video call is connected, the push server 1320 transmits a voice recording announcement to the second terminal 1200 ). Since the second terminal 1200 displays the push message received from the push server 1320 on the phone application, the recent call list, and the address book, the second terminal 1200 provides a call convenience function that allows the user to recognize the call recording do.

First, call connection (incoming / outgoing) is performed between the first and second terminals 1100 and 1200 by phone applications installed in the first and second terminals 1100 and 1200 (S500). As the call connection is established, voice / video data according to the call is transmitted and received between the first and second terminals 1100 and 1200.

The first terminal 1100 detects an event requesting recording during a call, encodes a request message requesting recording of the call during a call, and transmits the encoded message to a call notification server 1300 (S510 ). In the case of a multi-party call, the request message may be transmitted to all terminals connected to the call through the call announcement server 1300 during the call.

The call announcement server 1300 confirms whether the counterpart terminal (s) is a subscriber of a call announcement service during a call or a subscriber management server 1310 And transmits a subscriber information request message (S520).

The call announcement server 1300 receives the subscriber information response message from the subscriber management server 1310 in operation S530 and transmits the request message to the push server 1320 (S540). ≪ / RTI > In the case of a terminal that can not receive the request message, the call announcement server 1300 transmits a reject message rejecting call recording to the first terminal 1100, Restricting the execution of recording during a call in response to a message.

The push server 1320 transmits the request message to the counterpart terminal in response to the push request message (S550).

Although not shown in the drawing, the counterpart terminal, that is, the second terminal 1200 receiving the request message may receive an approval message to approve the request to start recording of the call on the first terminal 1100 based on user input or The push server 1320 transmits a response message to the push server 1320 in response to the request message (S560).

The phone application installed in the second terminal 1200 may display a push message received from the push server 1320 on the phone application, the recent call list, and the address book to provide a user-perceived call convenience function. Furthermore, the second terminal 1200 may output screen information formed on the touch screen to receive a user input for selecting either the approval message or the rejection message.

Thereafter, the response message is transmitted from the push server 1320 to the call announcement server 1300 (S570), and is transmitted from the call announcement server 1300 to the first terminal 1100 S580). The response message may be transmitted to the first terminal 1100 directly from the push server 1320.

If the response message is the acknowledgment message, the first terminal 1100 starts recording during the call (S590).

Alternatively, if the response message is a rejection message or if the acknowledgment message is not received within the reference time from the time when the request message is transmitted, the first terminal 1100 restricts the execution of recording during a call. That is, in spite of the user's request, recording is not made during the call.

When the call recording is started by the approval message or the execution is restricted by the rejection message, the first terminal 1100 outputs a response of the second terminal 1200 in a form recognizable by the user do.

Meanwhile, when the first terminal 1100 is in the call recording mode, the second terminal 1200 can automatically perform call recording even when a separate user request is not received. This is to solve the problem of unbalance of information that the recording file is generated only in the first terminal 1100 and is not available to the user of the second terminal.

For the same reason, when the first terminal 1100 records a call during a call, the call announcement server 1300 hooks up signals received and transmitted between the first and second terminals 1100 and 1200, And store the generated recording file in a predetermined server. Each user of the first and second terminals 1100 and 1200 can download or reproduce a recording file stored in the predetermined server through user authentication. As a result, it is possible to prevent a recording file from being transformed or maliciously used by a third party.

As the recording in the call starts, the operations described above in Fig. 2 are subsequently performed.

The second terminal 1200 transmits the response message to the first terminal 1100 when the request message for requesting recording during the call is transmitted from the first terminal 1100 to the second terminal 1200, The operation of transmitting data to the base station will now be described in more detail.

FIGS. 6A and 6B are illustrations for explaining a method for rejecting recording during a call.

First, the first terminal 1100 receives an execution command related to execution of recording during a call from a user. The first terminal 1100 may determine that a menu related to recording during a call is selected by a touch or the like and a voice command is received.

The first terminal 1100 controls the wireless communication unit to transmit the request message requesting recording of the call to the second terminal 1200 when an execution command related to execution of recording during the call is received. The request message may be transmitted to the second terminal 1200 by the method described above with reference to FIG.

When the request message is received, the second terminal 1200 transmits an approval message for approving the request for the call recording to be executed in the first terminal 1100 or a reject message Based on user input. Then, the generated first message is transmitted to the first terminal 1100 as a response message to the request message.

The second terminal 1200 may provide a user interface 620 configured to receive a user input to generate the message.

The user input may be input to the terminal in various manners, such as a user gesture, speech recognition, and the like.

For example, as shown in FIG. 6A, screen information formed to receive a user input for selecting either 'approval' or 'rejection' may be output to the touch screen. The terminal can selectively generate an approval message or a reject message based on the touch input applied to the screen information.

As another example, as shown in FIG. 6B, it can be audibly informed that a call-in-record request has been received, and user input to the call-in request can be input using voice recognition. That is, voice commands for approving or rejecting a recording request can be input using speech recognition for a natural language. For example, when a natural language of 'Do not Record' is inputted, a reject message is generated and an approval message can be generated when a natural word 'OK to record' is inputted.

The first terminal 1100 restricts recording during a call until the response message is received. In other words, the call recording is not executed until the other party agrees. Then, it can announce that the other party is waiting for the recording approval until the response message is received (610).

When an acknowledgment message is received within a predetermined time from the time of transmitting the request message, recording is started during the call. If the reject message is received or the acknowledgment message is not received within the predetermined time, the user is restricted from recording during the call because the user of the call does not have consent. At this time, the terminal can guide the reason why the recording is not performed during the call (rejection of the other party or non-response of the other party, 612) in a visual and auditory manner.

According to this example, since recording during a call is made only when there is agreement of the other party, recording is prevented in advance by an illegal procedure. In addition, since the user interface for accepting or rejecting the request for recording during the call is provided, the user can conveniently respond to the other party's request.

7A and 7B are flowcharts for explaining a control method for pausing recording during a call in a counterpart terminal, and FIGS. 8A and 8B are views illustrating an operation of the first and second terminals according to the control method of FIG. 7 admit.

In operation S710, the first terminal 1100 may record data during a call. Accordingly, the second terminal 1200 outputs guidance information for informing that the first terminal 1100 is performing recording during the call.

If a predetermined condition is satisfied during recording during the call, the second terminal 1200 transmits a suspend request message requesting to suspend recording of a call in progress from the first terminal 1100 to the first terminal 1100) (S720).

The predetermined condition is that a user input requesting a pause is applied to the second terminal 1200.

For example, as shown in FIG. 8A, if a call recording is made at the other party's terminal, the terminal may output an icon 830, which is configured to generate a pause request message, to one area of the touch screen. The user can touch the icon 830 to pause recording during a call.

As another example, a voice command ('off the record for 1 minute') related to a pause can be input, as shown in FIG. 8B. The terminal generates a pause request message having a predetermined condition based on the voice command and transmits the pause request message to the counterpart terminal so that a pause corresponding to a predetermined condition is performed. The other terminal responds to the pause request message and performs the pause according to the predetermined condition. According to the example shown in FIG. 8B, the first terminal 1100 can pause recording during a minute for one minute, and resume recording again after one minute has elapsed.

The first terminal 1100 pauses recording based on the suspend request message in step S712 and the second terminal 1200 notifies the user of the recording pause in step S724. If recording is paused, the first and second terminals 1100 and 1200 may output information 810-840 related to recording pause.

Meanwhile, the second terminal 1200 may transmit a pause release request to the first terminal 1100 (S724). The first terminal 1100 may resume recording in response to the release request (S718).

Thereby, even when the recording during communication is executed in the other party's terminal, the user can pause the recording performed in the other party's terminal.

FIGS. 9A, 9B, 9C, and 10 are exemplary diagrams for explaining a control method of guiding recording during a call after a call is terminated.

Referring to FIG. 9A, when the call is terminated, the first and second terminals 1100 and 1200 can output recent call records to the touch screen. The recent call records include at least one call record. The call record 900 includes information on origination / reception, origination / reception time, and information on the other party's terminal.

Furthermore, if a call recording is made, the call record may further include a graphical object 910 to inform that the call recording has been made. The graphic object 910 may be an image of a different type according to the type of terminal that recorded the call. Here, different images mean images having different shapes, lengths, colors, and the like, for example.

For example, a first image having a first type may be displayed when a conversation is recorded during a conversation, and a second image having a second type may be displayed when a conversation is recorded in the terminal. And if a recording is made during both calls in both parties, a third image having a third form can be displayed.

That is, for the convenience of the user's call, it is possible to expose a separately identifiable graphic object to the recent call list for the call history recorded during the call.

9B, when the user touches the graphic object 910, the terminal reproduces a file generated by recording during a call and outputs the playback screen 920. Alternatively, as shown in FIG. 9C, As shown, detailed information 940 relating to recording during a call can be output.

The detailed information related to the recording during the call includes at least one of the information about the call participants, the total talk time, the total recording time, the start and end time of the call, the start and end time of recording, .

If the file generated by the call recording is stored in a memory or a predetermined server capable of downloading, the terminal plays the file in response to a touch applied to the graphic object 910, and outputs the playback screen . The playback screen may include a name of the file, graphic objects capable of controlling playback, and a progress bar for guiding the playback state.

Alternatively, a file generated by recording during a call may be stored only in the other party's terminal. In this case, the terminal may output a graphic interface configured to request a file to the counterpart terminal or request a file deletion in response to a touch applied to the graphic object 910.

Referring to FIG. 10, the first and second terminals 1100 and 1200 may display detailed information 1000 of a contact item or a contact item of the contact items. If a call recording is recorded for any one of the contact items, a graphic object 910 may be further included to inform that the call recording has been performed.

Thus, the user can confirm the contact item and confirm the recorded information recorded during the call with the other party.

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).
