Description

Phone number registration method and mobile communication terminal {METHOD FOR TELEPHONE NUMBER REGISTRATION AND MOBILE COMMUNICATION TERMINAL THEREFOR}

The present invention relates to a mobile communication terminal, and more particularly, to a telephone number registration method and a mobile communication terminal.

Recently, due to the development of technology, mobile communication terminals including a voice recognition function have been released. The speech recognition function is a technology that automatically extracts language information included in a human voice and provides necessary information to a desired person. In the case of a mobile communication terminal, a voice recognition function is used to analyze a feature of a voice input through a microphone and perform a specific operation on a voice command. For example, in a mobile communication terminal, a user may conveniently perform a function such as selecting a menu or searching a phone book through a simple command. In addition, when the call is received from the mobile terminal, the user can identify who is calling through the speaker recognition function, which is one of voice recognition functions. Therefore, when the speech recognition function is applied to the mobile communication terminal, the user has a convenience of using various functions more easily.

On the other hand, in recent years, due to the rapid development of the information society, a mobile communication terminal with a video call function has been introduced in addition to a mobile communication terminal that merely delivers a voice. Such a mobile communication terminal usually includes a camera equipped with a face recognition technology to acquire a face of a subject during a video call. Therefore, there is an advantage that the called party and the caller can talk to each other while looking at each other's faces.

As described above, the conventional mobile communication terminal provides a voice recognition function and a video call function for the user's convenience. However, these functions are still applied to only a few simple functions, so their use is limited.

In the conventional mobile communication terminal to which the voice recognition function is applied, its use range is limited to simple functions such as menu operation and phone number search. In addition, the conventional mobile communication terminal to which the speaker recognition function is applied can check who is calling, but this is less accurate than the case where the user checks the speaker.

Meanwhile, in the conventional mobile communication terminal, when a user wants to register a phone number, the user must input caller information in a corresponding menu. In the related art, when a call is received, caller information is provided based on a phone book, and thus, a user must input caller information such as a name, affiliation, and the like into the phone book in order to receive the caller information. Therefore, the conventional mobile communication terminal is troublesome by registering a phone number and there is a problem that it takes time unnecessarily. In addition, the conventional mobile communication terminal has a limitation that the caller information can not be provided to the user when the calling telephone number is a number not registered in the phone book.

Accordingly, the present invention provides a phone number registration method and a mobile communication terminal for allowing a called party to easily check the information of the caller even when a call is received from a caller who is not registered in the phone book.

In another aspect, the present invention provides a phone number registration method and a mobile communication terminal for acquiring information of various callers to be registered more conveniently in the phone book.

The present invention to achieve the above is a method for registering a telephone number in a mobile communication terminal, the step of determining whether there is a caller information corresponding to the calling telephone number when a call is received, and if there is no caller information voice call or video call Determining whether a call is initiated; analyzing a conversation pattern based on contents of a call between a called party and a caller when the voice call is started; extracting caller information from the analyzed conversation pattern; and after the call ends. And storing the extracted caller information in correspondence with the calling telephone number.

In addition, a mobile communication terminal for registering a telephone number, the display unit for displaying at least one of an outgoing telephone number and caller information when a call is received, a memory for storing the outgoing telephone number and the caller information, the called party after the call start And a voice processor for recognizing a caller's voice and outputting each of the recognized voices, and when the call is received, determines whether caller information corresponding to the calling telephone number is in the memory, and if there is no caller information, a voice call. Or when the voice call is started by determining whether a video call is started, analyzing a conversation pattern based on the contents of the call between the called party and the caller recognized by the voice processing unit, and extracting the caller information from the analyzed conversation pattern. To retrieve the extracted caller information after the call ends. And a control unit for storing in the memory in correspondence with a previously dialed telephone number.

The present invention provides a convenience to easily obtain the information of the caller to register more easily in the phone book. In addition, the present invention has an advantage of more accurately checking the information on the caller by providing the caller's information in various formats such as voice or image as well as text. In addition, the present invention has the advantage of displaying the information of the caller by identifying the caller's voice even if the call is received through a public phone or a general phone.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed description of preferred embodiments of the present invention will be given with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The present invention proposes a telephone number registration method and a mobile communication terminal. The mobile communication terminal according to the present invention determines whether there is caller information corresponding to the calling telephone number when the call is received. If there is no caller information corresponding to the calling telephone number, the mobile communication terminal determines whether a voice call or a video call is started, and extracts caller information according to the corresponding call mode. At this time, the extracted caller information is stored in correspondence with the calling telephone number after the call is terminated and is used for displaying the caller when a call is received. Therefore, when a call is received from the mobile terminal, the user may easily check the caller through the stored caller information.

Hereinafter, a block diagram of a mobile communication terminal for registering a telephone number according to an embodiment of the present invention will be described with reference to FIG. 1.

Referring to FIG. 1, the mobile communication terminal according to the present invention includes a control unit 100, a memory unit 110, a wireless unit 120, a voice processing unit 130, an image input unit 140, a display unit 150, and a key input unit. And 160. First, the controller 100 performs an overall control operation of the mobile communication terminal. In particular, in the present invention, when the call is received, the control unit 100 determines whether there is caller information corresponding to the calling telephone number. Here, the caller information refers to at least one of the sender's name and affiliation. If there is no caller information, the controller 100 determines whether a voice call or a video call is started.

When the voice call is started, the controller 100 analyzes the conversation pattern based on the contents of the call between the called party and the caller. In an embodiment of the present invention, the control unit 100 extracts one or more key words according to the contents of the call between the called party and the caller after the start of the call in order to analyze the conversation pattern. The controller 100 compares the extracted one or more key words with pre-stored idioms to determine whether there are key words that match the idioms. When there are key words that match the idioms, the controller 100 checks the context of the conversation and extracts key word information related to at least one of caller information, that is, the name and affiliation of the callers. The controller 100 stores the extracted key words as caller information after corresponding to the corresponding outgoing telephone number.

Meanwhile, when the video call is started, the controller 100 first acquires a still image from the caller's image transmitted from the calling terminal. The controller 100 recognizes an area where a face is displayed in the still image and obtains a caller's face image. Subsequently, the controller 100 stores the obtained caller's face image corresponding to the calling telephone number when the video call ends.

As described above, the control unit 100 stores caller information in a corresponding method according to whether it is a voice call or a video call. Therefore, the controller 100 may display the stored caller information in advance together with the corresponding calling telephone number when the call is received again from the calling party.

The memory unit 110 connected to the control unit 100 may include a read only memory (ROM), a random access memory (RAM), and a voice memory for storing a plurality of programs and information necessary for controlling the operation of the mobile communication terminal. And so on. As such, the memory unit 110 includes a program memory and a data memory. The program memory stores program data necessary for controlling the operation of the mobile communication terminal, and the data memory is generated during control or during a predetermined operation by a user. Data is stored. In particular, according to an embodiment of the present invention, the memory unit 110 includes a phone book in which outgoing phone numbers and caller information for each outgoing phone number are stored, and a temporary phone book in which each stored caller information is deleted after a preset time. do.

The radio unit 120 transmits and receives an RF signal to and from the base station through the antenna ANT under the control of the controller 100. The voice signal processor 130 connected to the controller 100 is connected to the microphone MIC and the speaker SPK, and outputs the voice signal received from the microphone MIC to the controller 100. The voice data input from the controller 100 is converted into an audible sound through the speaker SPK and output.

The image input unit 140 refers to a camera sensor mounted on the mobile communication terminal, and generates a captured image of the corresponding subject. At this time, the generated image is converted into digital output under the control of the controller 100, and is transmitted to the calling terminal through the wireless unit 120 in the video call mode according to an embodiment of the present invention.

The display unit 150 receives and displays display data on key input data input from the key input unit 160 under the control of the controller 100, or displays an operation state and a plurality of information of the mobile communication terminal as icons and text. . The display unit 150 allows the user to visually know the state in setting or driving a required function under the control of the controller 100. In particular, the display unit 150 according to an embodiment of the present invention displays at least one of an outgoing telephone number and caller information when a call is received under the control of the controller 100. That is, the display unit 150 displays an outgoing call number when a call is received, and displays the caller information together with the outgoing call number when there is caller information corresponding to the outgoing call number. In addition, the display unit 150 displays a video of the user photographed from the video input unit 140 and a video of the caller transmitted from the calling terminal under the control of the controller 100 during the video call.

Subsequently, the key input unit 160 includes various keys including a numeric key and a character key to provide the control unit 100 with key input data input by the user. That is, the key input unit 160 outputs its own key input data according to the input of each key provided thereto, and applies the output key input data to the controller 100. Then, the controller 100 determines whether the key input data is the key input data according to the key input, and performs an operation corresponding to the determination result.

Hereinafter, a registration process of an outgoing telephone number in a terminal configured as described above will be described in detail with reference to specific embodiments.

2A is a control flowchart for registering an outgoing telephone number in the case of a voice call according to an exemplary embodiment of the present invention. Referring to FIG. 2A, the controller 100 checks an outgoing telephone number in step 200. The controller 100 proceeds to step 202 to determine whether the outgoing telephone number is a registered telephone number. To this end, the control unit 100 determines whether there is caller information corresponding to the corresponding outgoing phone number in the phone book.

If it is determined in step 202 that the checked outgoing phone number is a registered phone number, the controller 100 performs a corresponding function. That is, in this case, the controller 100 outputs the caller information stored in the phone book to the display unit 150 and performs a call function according to the user's selection.

If the outgoing phone number is not a registered phone number, that is, the controller 100 determines that the outgoing phone number does not have the caller information, the controller 100 displays the outgoing call number in step 204.

In operation 206, the controller 100 determines whether a call is started. When the call starts, the control unit 100 proceeds to step 208 and determines whether a video call or a voice call is started.

If the voice call is started in step 208, the controller 100 proceeds to step 210 and analyzes the conversation pattern. At this time, the controller 100 extracts key words from the contents of the call between the called party and the caller after the start of the call in order to analyze the conversation pattern. In detail, the control unit 100 first recognizes the voice of the called party and the caller in order to extract key words. According to an exemplary embodiment of the present invention, voices of the called party and the calling party may be divided according to whether the microphone vibrates. The controller 100 searches for and finds words similar to the recognized speech from a pre-stored vocabulary DB. In addition, the controller 100 identifies an important vocabulary among the searched vocabularies and extracts the key words.

According to an embodiment of the present disclosure, the controller 100 may predict key words used at the beginning of a call. This is because conversations to and from the beginning of a call are usually limited in a mobile communication terminal. That is, since a conversation such as a greeting or self introduction such as 'hello' and 'hello' is mainly performed at the beginning of the call, the controller 100 predicts the conversation pattern at the beginning of the call and stores idioms in advance. The idioms stored at this time can be a vocabulary that is used at the beginning of a call, such as' hello ',' hello ',' who ',' I '.' The controller 100 compares key words and idioms to check the context of the conversation between the called party and the sender.

 For example, the called party said "Hello. Who are you? ', The control unit 100 may predict that the caller will introduce themselves in a subsequent conversation. Accordingly, the control unit 100 has a caller saying 'hello. If you introduce yourself as 'Samsung electronics Jung Ji-hyun', identify 'Hello ~' as an idiom, and identify 'Samsung Electronics' and 'Ji Ji-hyun' as key words, respectively. Analysis of such a conversation pattern may be performed within a predetermined call initial time according to an embodiment of the present invention, but this is not limited thereto and may be changed in various ways.

When the conversation pattern is analyzed as described above, the controller 100 determines whether there is caller information in step 212. That is, the controller 100 determines whether keywords related to the caller's information are extracted from corresponding keywords in accordance with the checked dialogue context.

If the core words related to the caller information are not extracted and the caller information is not extracted, the controller 100 proceeds to step 214 to record a part of the conversation. In this case, the recorded data may be the caller's voice, and in some cases, the caller's voice may be recorded together. In addition, according to an embodiment of the present invention, if there is no caller information, the controller 100 may output a screen asking whether the user directly registers the caller information. In this case, the user can directly register the caller's information, thereby reducing the trouble of registering the phone number.

If the caller information is extracted or the conversation is recorded as described above, the control unit 100 proceeds to step 216 to determine whether the call is terminated. When the call is terminated, the controller 100 proceeds to step 218 and stores caller information or recorded conversation content in correspondence with the calling telephone number. At this time, the outgoing telephone number is stored in the temporary phone book or the phone book according to the user's selection. In detail, the controller 100 outputs the caller information to the phone book registration window when a user request for storing the caller information is requested. The controller 100 stores corresponding caller information in the phone book according to a user's selection.

The controller 100 stores the caller information in the temporary phone book when there is no user request to store the caller information, that is, when the caller information is not stored in the phone book. Accordingly, in the present invention, the user has the convenience of receiving the caller information based on the caller information stored in the temporary phone book without registering the calling phone number directly in the phone book. In addition, in the present invention, since the caller information stored in the temporary phone book is automatically deleted after a predetermined time in a time set by the user or in the system, the user has the convenience of separately managing necessary numbers temporarily.

 Meanwhile, when the video call is started in step 208, the controller 100 proceeds to step 220 of FIG. 2B. Here, symbol A is used to show that step 208 of FIG. 2A and step 220 of FIG. 2B are connected.

Hereinafter, referring to FIG. 2B, which is a control flowchart for registering an outgoing telephone number in the case of a video call according to an embodiment of the present invention, which is continued from step 208 of FIG. 2A. Referring to FIG. 2B, in the case of a video call, the controller 100 obtains a caller's still image in step 220. In operation 222, the controller 100 recognizes an area where a face is displayed in the still image obtained.

If the recognition is successful in step 224, the controller 100 proceeds to step 226 to obtain an image of the caller's face. If the recognition fails due to low reception sensitivity or poor call environment, the controller 100 proceeds to step 228 to record a part of the conversation. This is to store the caller's voice as caller information in place of the caller's face when the controller 100 cannot obtain the caller's face image.

In operation 230, the controller 100 determines whether the video call is terminated. When the video call ends, the control unit 100 proceeds to step 232 and stores the acquired face image or recorded conversation content in correspondence with the outgoing call number. That is, in the video call, the caller's face image is stored as caller information. If the face image is not obtained, the caller's voice is stored. In contrast, according to an exemplary embodiment of the present invention, a face image and a voice may be simultaneously acquired in a video call, and as in the case of a voice call, caller information may be detected and stored from the contents of the call.

The stored caller's face image or voice may be used as a caller indication when a call is received according to an embodiment of the present invention. That is, the present invention has an advantage in that the caller display service of various formats can be performed by displaying a face image when a call is received or by outputting a user's voice as a ring tone.

Meanwhile, according to an exemplary embodiment of the present invention, even when a caller transmits a call through a public phone or a general phone instead of his own terminal, the mobile communication terminal can identify the caller by using voice pattern recognition. That is, in this case, when the caller's voice pattern is additionally registered as caller information and the next call is received from the caller, caller information corresponding to the caller's voice may be displayed.

In detail, the controller 100 recognizes the caller's voice and analyzes the voice pattern when the call is received by an unregistered phone number. In this case, the voice pattern may be analyzed through a voice level, a volume, a pronunciation, and a speech speed. The voice pattern thus analyzed is stored in the phone book or temporary phone book corresponding to the corresponding outgoing phone number. In addition, according to an embodiment of the present invention, the voice pattern may be stored together with information of the caller extracted according to a conversation pattern between callers or the caller's face image obtained during a video call.

Accordingly, even though the caller subsequently transmits the call through a public phone or his home phone instead of his own terminal, in the present invention, the mobile communication terminal analyzes the caller's voice pattern and identifies the caller to the user. There is an advantage in providing accurate information such as name or picture.

Hereinafter, an exemplary diagram of a screen for registering an outgoing telephone number according to an embodiment of the present invention will be described with reference to FIG. 3.

When the user selects a menu for checking a recently received telephone number in the mobile communication terminal, the user can see a screen as shown in FIG. 3 (a) illustrates a list of recently received telephone numbers. At this time, the caller information corresponding to each telephone number is displayed. That is, the caller information extracted from the contents of the call with the caller through the process of FIGS. 2A and 2B is displayed corresponding to the call number.

3 (a) shows that the extracted caller information 'Lee Young-hee' and 'Samsung Electronics Researcher' are displayed corresponding to the corresponding phone numbers, respectively. And '010-123-4567' (300) shows that the caller information is displayed instead of the caller information because the caller information is not extracted from the contents of the call. Here, the user may select one item and then press the menu button 302 to check the information of the corresponding caller.

For example, when a user selects an item 300 displaying a phone number and presses the menu button 302, the menu items 306, 308, and 310 are displayed while the corresponding phone number 304 is indicated as shown in FIG. do. The menu items displayed at this time may be 'registering' 306, 'voice listening' 308, 'viewing picture' 310, and the like. Therefore, the user can easily check the information on the caller by listening to the voice or viewing the picture through the menu items. In addition, when the user wants to register the corresponding phone number in the phone book, the user may select 'register' 306 to perform a registration process through the screen as shown in FIG.

Referring to FIG. 3 (c) in detail, in the embodiment of the present invention, when a user wants to register a phone number, information of a caller previously extracted is automatically displayed on each item of a phone number registration menu. In this case, when the name and affiliation of the caller corresponding to the registered phone number are not extracted, the user may directly input information to be stored in the corresponding item. On the contrary, if both names and affiliations are extracted, the user can easily and quickly register a phone number by simply pressing an OK button.

As described above, the present invention has the effect of easily registering the caller's information in the phone book by using the voice recognition method and the face recognition method. In addition, the present invention provides a voice and a face image as well as simple information such as a caller's name or affiliation, so that the caller information can be checked in various ways.
