Hereinafter, with reference to the drawings will be described in detail an embodiment according to the present invention.

1 is a block diagram showing the overall configuration of a communication service system according to an embodiment of the present invention. The service system includes input terminals 11 of a user who performs data registration while communicating with a server through a switching center 15 providing a general communication service, a server 13 providing a service related to character information, and a communication network 12. And communication terminals 17 of a user who can receive communication services such as voice / data communication through the communication network 16 and the exchange station 15, and the server 13 and the exchange station 15 are connected to the communication network ( Communicate via 14). On the other hand, the server 13 and the switching center 15 is configured to be physically geographically separated and connected through the communication network 14, or the switching center 15 is provided with functions such as data storage and processing of the server 13; If implemented in a computer or data storage device, the entire function can be performed in one system without a separate communication network. In this case, it is convenient to describe each individual function by separating the unique functions of the server and the switching center.

The service server 13 registers the character information corresponding to the communication terminal of the inputter (user of the communication terminal) through the communication network 12 from the input terminals 11 and stores it in the character database 132. The input terminals 11 include a personal computer 111, its own mobile communication terminal 112, a wired telephone, or the like, and can directly transmit audio / video data to the server 13 through a predetermined communication network, or Any communication device capable of performing a function of selecting a menu (for example, ARS method) according to a menu provided by the user is sufficient. Here, the character data may include not only a still image such as a picture or a moving image and image data played for a predetermined time, but also audio data such as character data and / or music, such as image data and text, and also constitute only text or audio data. Can be.

The server 13 includes a character register 133 that receives character data and the like into the input terminals 11 and registers them. When the user wants to register a character, when the user connects to the server 13 through the input terminals 11 and directly inputs the character information prepared in advance to the server 13, the character registration unit 133 is a character database Save at 132. The data stored in the character database 132 is shown in FIG. 2B, which is a subscriber ID 24 and a telephone number (or ID for specifying a communication terminal) 25 of the subscriber ID 24 as information for identifying a registrant. Number character information 26 corresponding thereto is stored.

The character registration unit 133 may further receive and store character information for displaying a situation such as a missed or difficult call from a subscriber. That is, the character database 132 of the server 13 may store at least two or more state character information that can distinguish and express at least two or more situations from the user of the communication terminal together with the character information corresponding to the user's communication terminal number. For example, the situation information 27 may include a situation such as a meeting, driving, and a business trip, and the situation character information 28 may be easily recognized by the other party. When the situation character information is stored, when the user is in any one of the registered situations, information about the situation can be set in advance.When the user's communication terminal is called, the status character information corresponding to the already set situation information is sent to the caller. Transmits the status character information to the sender communication terminal by transmitting to the terminal. The transmission of status character information to the calling party communication terminal is usually made through the switching center.

Meanwhile, the server 13 may further include a sample database 131 in which various kinds of characters are stored in advance, and the server 13 classifies the characters in the sample database 131 according to an appropriate classification method and allows the user. By letting the user select this, the user can easily register the character.

When the character information is requested from the switching center 15, the server 13 extracts the character information corresponding to the character information and transmits the character information to the switching center 15. The number receiving unit 134 transmits the caller's telephone number (which is used as a general term for information for specifying the caller's communication terminal) transmitted from the switching center 15, and includes not only the telephone number but also the caller's ID. Receive. The character checking unit 135 searches the character database 132 and checks whether there is a stored character corresponding to the received telephone number. The character transmission unit 136 transmits the character corresponding to the telephone number to the switching center 15 if present or information indicating that there is no.

Also, the character registration unit 133 receives another communication terminal number of another person from the input terminal 11 of the user who registered specific character information, and the character transmission unit 136 receives the user's communication terminal number and the character set by the user. Information and other communication terminal numbers can be transmitted to the switching center 15. Then, the switching center 15 calls a communication terminal corresponding to the other communication terminal number, and transmits the user's character information and the user's communication terminal number, so that the character information of the user to the communication terminal of another person corresponding to the user's terminal number. Can be stored. When the character is stored in this state, when the user communication terminal is called to another communication terminal, the user's character is automatically displayed on the screen of the other communication terminal.

Switching station 15 includes an exchange switching a call of a wired telephone through a telephone switching network, a base station switching a call of a mobile communication terminal through a mobile communication network, a system of switching communication between computers through a data communication network such as the Internet, and the like. In addition, while providing communication with the service server 13, a character providing service may be provided or a service may be directly provided by providing all of the functions of the service server.

The subscriber database 151 of the switching center 15 stores general information on the subscriber using the communication service. Referring to FIG. 2A, the subscriber database 151 basically includes an ID 21 and a telephone number 22 for identifying the subscriber. In addition, payment related information, such as a bank account or credit card number, may be stored. Here, the subscriber of the communication service includes not only a mobile communication terminal but also a communication terminal capable of communicating voice / video / data by wire or wirelessly with a communication terminal having a specific communication number or address as shown in the drawing.

The receiver transmits the character information registered corresponding to the caller's terminal number to the receiver communication terminal. It provides a communication service to display the character information of the caller to the communication terminal.

First, the user of the communication terminal accesses the server 13 and registers as a member to register character information corresponding to the telephone number of the user's communication terminal (30). The server 13 stores member information and character information (31). In this state, when the caller's call signal is received 32 from the switching center 15, the switching center 15 detects the calling party's telephone number 33 and checks whether the calling telephone number is registered in the server 13. Check (34).

If the character information corresponding to the caller's telephone number is registered in the server 13, the caller's registered character is transmitted from the server 13 to the switching center 15 (351), and the switching center 15 calls the receiver's communication terminal. The sender's character information is transmitted (352). The sender's character information is displayed on the receiver's communication terminal screen (353), and the receiver may check the content of the character information and then determine whether to receive it (37). If the receiver selects a call connection, communication is established (38) between the sender and the receiver via the switching center 15. If the character information corresponding to the caller's telephone number is not registered in the server 13, the switching center 15 may transmit the caller's telephone number to the receiver's communication terminal (361).

4A and 4B are flowcharts illustrating a method of previously storing caller's character information in a receiver's communication terminal and displaying the same on a screen according to an embodiment of the present invention. If the user calls another person's communication terminal, the other person's communication terminal provides a communication service that extracts and displays the stored character information corresponding to the caller's terminal number.

First, a member 40 is subscribed to the server, and then a subscriber (ie, a communication terminal user) receives his or her communication terminal number (or ID), character information corresponding thereto, and another person's communication terminal number (41). The server 13 transmits 42 the user's communication terminal number, character information, and another communication terminal number to the switching center 15. Switching station 15 calls (or connects) 43 a communication terminal corresponding to another communication terminal number to transmit a user's communication terminal number and corresponding character information to another communication terminal (44). It is stored in memory (45).

In this state, when the call is received by the other communication terminal (46), the number of the caller communication terminal is checked (47) to determine whether character information corresponding to the number of the caller communication terminal is stored in the memory of the own communication terminal. Search (48). If so, character information corresponding to the number of the caller communication terminal can be displayed on the screen to easily identify who the caller is. You can then decide whether to receive it.

On the other hand, in the embodiment of Figure 4 has been described with respect to the example of storing the character information of his own to the other communication terminal, as another example to transmit the character information to the other communication terminal to set as the character information for the other communication terminal can do. In other words, it is a gift of character information to others. In this case, the third party communication terminal stores the transmitted character information and when the other communication terminal is called, the previously stored character information is displayed on the receiver communication terminal.

FIG. 5 is a flowchart illustrating a method of displaying information according to a receiver's situation to a caller according to an embodiment of the present invention. When the user's communication terminal is called in advance by setting the user's situation according to the status character information, FIG. It provides a communication service that can inform the user of the situation by transmitting the status character information corresponding to the caller communication terminal.

The user connects to the server 13 and registers situation character information corresponding to the situation information as described in FIG. 2B (51). If the user is in one of several situations already registered, the user sets context information according to his current situation (52). Such situation information can be set by directly connecting to the server 13 using its own communication terminal or another communication device, or can be set through the switching station 15 using its own communication terminal.

If the user has a call in the state where the situation information is set (53), the situation character information corresponding to the situation information set by the receiver is transmitted to the caller communication terminal (54). Specifically, when the receiver's communication terminal is called from the caller's communication terminal, the server receives the receiver's terminal number from the switching center, and if the status character information corresponding to the terminal number of the receiver is transmitted to the switching center, the switching station is switched to the calling terminal's communication terminal. Send character information. The caller communication terminal receives the status character information and displays it. At this time, the number character information corresponding to the receiver terminal number together with the status character information corresponding to the situation information can be transmitted to the caller communication terminal, and the caller communication terminal responds to the number character information and situation information corresponding to the receiver communication terminal number. It is also possible to display the status character information together.

In addition, the user of the communication terminal may set in advance whether or not to receive a call while setting the situation information, and may determine in advance whether or not to make a call according to the reception information if there is a call from another communication terminal. For example, in a situation in which reception is impossible, the sender may be notified in advance of an unreceivable message.

FIG. 6 is a block diagram showing the configuration of a communication terminal operating properly for a communication service as described above according to an embodiment of the present invention.

The communication terminal detects whether or not the character memory 61 stores character information corresponding to at least one telephone number, and if the call reception signal includes a telephone number and character information of the caller communication terminal when a call is received from another communication terminal. If the character information is included in the signal analysis unit 62 and the received signal, the received character information is displayed on the display unit 64 such as a screen. If the received signal does not include the character information, the character memory 61 is searched for. And a display control section 63 which checks whether there is stored character information corresponding to the caller's telephone number, and if so, displays the stored character information on the display section 64. The display unit 64 includes a screen such as a liquid crystal for displaying an image or a character, a speaker for outputting sound, and a vibration means for physically moving the communication terminal.

The display control unit 63 may selectively display any one of the received character information and the pre-stored character information as information for calling party identification, or may display both at the same time. Is likely to be the latest information, so it is desirable to display it. In addition, the caller's telephone number may be displayed together with the character information.

In addition, the communication terminal further includes an input unit 65 for confirming a caller according to the character information displayed on the display unit 64, and an input unit 65 for inputting reception, and a reception unit 66 for transmitting the received reception information to the switching center. It can be provided.

FIG. 7 is a flowchart illustrating an example of a method of displaying caller information when a call is received by the communication terminal illustrated in FIG. 6, wherein the received character information, prestored character information, and caller's telephone number are displayed as caller display information. This is an example of controlling the display order.

When a call is received by the communication terminal (71), it is checked whether the call reception signal includes character information together with the caller's telephone number (72). If the received signal includes the character information, the received character information is displayed on the screen of the communication terminal (741). If the received signal does not include the character information, the memory of the communication terminal is searched for and stored in response to the caller's telephone number. If there is information (742), and if there is (75), the previously stored character information is displayed on the screen of the communication terminal (751).

If the received signal includes the caller's character information, the character information stored in correspondence with the caller's phone number and the received character information in the memory of the communication terminal are different or not stored in the memory. Character information can be stored in memory.

In each embodiment of the present invention, a service indicating the caller's call status may be further added. The server may store, for example, about 10 general user's general situation information together with graphic information and / or voice information, or register and use information required by the user. The sender can set the current situation information according to the situation of them. When the user makes a call in this state, a message (character information) related to the caller's situation is displayed on the receiver's communication terminal. Here, the context information refers to a situation display character that can be frequently used by subscribers among various status displays such as watching a movie, class, meeting, etc., stored on a database, and, if necessary, a calling situation display function is selected. This message is then communicated to other communication terminal users.

The server checks the time of using the character information for each member function, and may charge a fee for using the character information and / or a service for using the server, and the cost may be charged together with the usage fee of the communication terminal. In addition, even when the character information is transmitted to another terminal, a certain fee can be added, and if necessary, the usage time can be limited every month.

The character information set by the user is an image that can represent the personality, image, or taste of the person or the company, and includes a photograph of his face, a family picture, a logo, etc., and allows the receiver to easily know who the caller is. It would also be better if it could provide pleasure. In addition, only one character need not be set for each individual (or company or a specific group), and a plurality of characters may be registered and a range of callers to be sent for each character may be determined. For example, the first character may be set as if the caller is a communication terminal of a family, and the second character may be set as if the caller is a communication terminal of a co-worker. It is necessary to set information (eg, name, etc.) that can be done. If a general caller who is not specially set up, one (or plural) characters may be selected and transmitted.

The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.

As described above, according to the present invention, through a server having a picture (image) or other appropriate information such as a character personally prepared by a communication subscriber connected to a computer of a base station or an exchange station to display a caller on a communication terminal, By sending from the base station or the switching center to the receiver's communication terminal, the caller can be easily identified by looking at the character content displayed on the LCD screen of the receiver communication terminal. By using the company's character or logo that expresses the image of the company instead of the phone number, the character of the caller can easily know who the recipient is, and it can be enjoyable at the same time using the communication device. When a user is in a situation where he or she cannot receive a communication device, the absence status can be displayed.

In addition, before the communication service user calls the user of the other communication terminal, the character related to the user is transmitted to the communication terminal of the other party and stored in advance. When the user calls the other communication terminal, the previously stored caller character of the receiver communication terminal is stored. It is displayed on the screen so you can easily check the caller. In this case, the character information is stored in the memory of the counterpart communication terminal in advance, so that a process such as data inquiry / detection to the server at the time of the counterpart call is unnecessary, thereby reducing the time required for the call connection.

On the other hand, the communication service user may store the character representing the missed state (or difficult to answer the call) in advance in the service server or the communication device, and when the call is made to the user, the information about the state of the user may be more appropriately transmitted to the counterpart.

In a modern society where personality is emphasized, it is possible to express yourself by using a character that suits your personality or taste in a communication terminal such as a mobile phone. It can be easily recognized and the caller can be an opportunity to emphasize their image to the other party.
