Prints out and prompts for another character number.

2 is a diagram showing in detail the configuration of the character number translation service system 500 according to the present invention.

Character number conversion service system 500 is a user management means 510 for receiving and managing information of a user using the character number conversion service, wireless character number management to receive and manage the character number from the caller's mobile communication terminal 100 Wired character number management means 530 for receiving and managing the ASCII code converted from the DTMF signal transmitted by the sender's wired terminal 200 from the mobile communication network 300, and analyzing the ASCII code as a character number. Wired character number analysis means for converting 540, character number converting means 550 for converting a character number into a matching terminal number, a character for transmitting the converted terminal number to the mobile communication network 300 or PSTN 400 It consists of the number transmission means 560, the control part 570, and the database 580. FIG.

First, the user management means 510 receives the terminal numbers 100 and 200 from a user such as an individual or a company and a character number corresponding to the name, nickname, or company name, and stores them in the database 580 for initial setting. At this time, the user management means 510 provides a format for inputting the terminal number and the character number to the user, and searches for the character number input by the user to input another character number if there is the same character number.

The wireless character number management means 520 receives and manages the character number of the text message field input by the caller using the mobile communication terminal 100.

The wired character number management unit 530 is a means for receiving and managing call connection information from the wired terminal 200 when the caller attempts to make a call by inputting a character number display symbol using the wired terminal 200. When the DTMF signal is received from the communication network 300, two exemplary embodiments will be divided into a wired terminal for transmitting a DTMF reply and a wired terminal for not transmitting a DTMF reply.

First, in case of a terminal having a function of analyzing a dual tone multifrequency (DTMF) signal transmitted from the mobile communication network 300 and transmitting a response thereto as a DTMF signal, when a user inputs a character number display symbol and a character number The mobile communication network 300 receives the character number display symbol from the wired terminal 200 capable of DTMF reply and transmits a signal for requesting a DTMF signal matching the character number to the calling wired terminal. Subsequently, the mobile communication network 300 switch receives the extended DTMF signal of the hexadecimal number transmitted from the PSTN 400 switch by converting the character number into an ASCII code and converting it into an extended DTMF signal. The ASCII code is converted to the corresponding ASCII code and transmitted to the character number conversion service system 500. The wired character number management unit 530 receives and manages the ASCII code converted from the DTMF signal from the mobile communication network 300 switch.

Second, in the case of a terminal that analyzes DTMF (Dual Tone Multifrequency) transmitted from the mobile communication network 300 and does not transmit a response thereto, the wired character number management unit 530 may not transmit a DTMF reply. Receiving a character number display symbol from the transmission of the announcement including any one of a variety of Hangul input method (for example, Cheonjiin, Quickta, Naragle, Hangul unification 2000, etc.) to enter the character number. The wired character number management unit 530 transmits a signal to the character number conversion unit 550 so as to retrieve a terminal number corresponding to the character number when receiving the character number input by the caller.

Under the control of the control unit 570, the wired character number analyzing unit 540 receives and analyzes an ASCII code transmitted by the wired character number managing unit 530, converts the ASCII code into a character number, and converts the result into a character number converting unit ( 550).

The character number converting means 550 matches the character number received by the wireless character number management means 520 and the character number received by the wired character number analyzing means 540 after being converted or converted under the control of the controller 570. To the terminal number. The character number converting means 550 compares the character number corresponding to the terminal number stored in the database 580 with the character number transmitted from the calling terminal and converts the character number input by the caller into the terminal number with reference to the database 580. After the conversion, the data is stored in the database 580.

The character number transmitting means 560 transmits the information converted by the character number converting means 550 into the terminal number to a switch in the mobile communication network or the PSTN under the control of the control unit 570, thereby providing a call path to the caller terminal and the called party terminal. To be connected.

3 is a flowchart illustrating an exemplary operation of the character number conversion service system 500 according to the present invention, and illustrates a case in which the caller uses the mobile communication terminal 100.

The sender inputs a text number (for example, ABC) in a text message field using the mobile communication terminal 100 and inputs a text number display symbol 011 * in the called party number field (S101). When the exchange receives 011 * from the mobile communication terminal 100, it transmits the ABC and the called party terminal 100, which are the character numbers entered in the text message field, to the character number conversion service system 500 (S103).

When receiving the ABC and the called party number, the wireless character number management means 520 transmits a character number reception signal to the character number conversion means 500 (S105). Subsequently, the character number converting means 550 searches whether the same character number as the received character number exists in the database 580 (S107).

If there is the same character number as a result of step S107, the character number converting means 550 selects the terminal number matching the same character number stored in the database 580, and transmits the calling terminal number along with the terminal number to the character number transmitting means. In step 109, the process transmits to step 560.

When receiving the converted terminal number and the calling terminal number from the character number converting means 550, the character number transmitting means 560 transmits the called terminal number to the exchange using the calling terminal number (S111). Subsequently, the exchange attempts to make a call connection between the caller's mobile communication terminal 100 and the called party's terminal by using the called terminal number transmitted by the text number transmitting means 560 (S113). The exchange receives a response signal from the called party terminal (S115), and a call path is connected to the calling party's mobile communication terminal and the called party's terminal (S117).

If there is no identical character number as a result of step S107, the character number converting means 550 transmits a message to the exchange that there is no same character number as the character number of the called party that the caller wants to talk to (S119). When the exchanger receives a message from the character number converting means 550 that the caller does not have the same character number as the character number of the called party, the exchange transmits the information indicating that the call connection is impossible (S121).

4 is a flowchart illustrating another embodiment of the operation of the character number conversion service system 500 according to the present invention, and illustrates a case in which the caller uses the wired terminal 200.

In response to the DTMF signal transmitted from the mobile communication network 300, a letter number indicating symbol (for example, 011 *) and a letter number A are obtained using the wired terminal 200 having a function of automatically transmitting a DTMF signal. Input and transmit a call request signal (S201). The PSTN 400 switch routes the call request signal including the letter number symbol to the switch 300 of the mobile communication network 300 (S203). Subsequently, the mobile communication network 300 exchange transmits the DTMF signal for requesting the called party's character number to the wired terminal 200 (S205). The wired terminal 200 converts the recipient's character number except for the character number display symbol (011 *) inputted by the caller into an ASCII code, converts the ASCII code into an extended DTMF signal, and moves it through the PSTN 400 switch. The communication network 300 transmits to the exchange (S207). The mobile communication network 300 receives the extended DTMF signal corresponding to the character number and converts it to an ASCII code corresponding to the DTMF signal (S209).

When the wired character number management unit 530 receives the ASCII code and transmits the ASCII code to the wired character number analyzing unit 540, the wired character number analyzing unit 540 converts the ASCII code into the character number (S211). The character number converting means 550 searches whether the same character number as the character number of the called terminal converted by the wired character number analyzing means 540 is stored in the database 580 (S213).

If there is the same character number as the character number of the called terminal as a result of step S213, the character number converting means 550 selects and converts the terminal number matching the character number of the called terminal stored in the database 580 (S215). ). Subsequently, the text number transmitting means 560 outputs the converted called terminal number and calling terminal number so that a call path is formed between the called terminal and the calling terminal (S217).

Where the character number transmitting means 560 outputs the called terminal number and the calling terminal number in step S217, when the called terminal is a mobile communication terminal and a wired terminal, it is a switch in each mobile communication network or PSTN.

If there is no character number identical to the character number of the called terminal as a result of step S213, the character number converting means 550 transmits the information that there is no same character number to the PSTN exchanger (S219). Subsequently, the PSTN exchange transmits an announcement that the call connection is impossible to the wired terminal 200 (S221).

5 is a flowchart illustrating another embodiment of operation of the character number translation service system 500 according to the present invention.

Response to DTMF Signal Transmitted to Character Number Conversion Service System 500 Wired terminal 200 that does not automatically transmit DTMF signal transmits a call request signal by inputting a character number indication symbol (for example, 011 *). (S301). The PSTN 400 switch routes the call request signal including the letter number symbol to the switch 300 of the mobile communication network 300 (S303).

Subsequently, the mobile communication network 300 exchange transmits a DTMF signal for requesting the called party's character number to the caller's wired terminal 200 (S305). The mobile communication network 300 checks whether a predetermined time for receiving the response DTMF signal from the wired terminal 200 has been exceeded (S307). When the predetermined time is exceeded as a result of step S307, the announcement message request signal is transmitted to the wired character number management means 530 (S309).

The wired character number management means 530 transmits a guidement for inputting a character number (S309). Here, the guidement is a guidement including any one of a variety of Hangul input method (for example, Cheonjiin, Quickta, Naragle, Hangul Unification 2000, etc.) to enter a character number, the message entered by the user is literally The character number conversion service system 500 is transmitted. The wired character number management unit 530 receives a caller's input character number and transmits a signal to the character number conversion unit 550 that a new character number has been received (S313). The character number converting means 550 receives the new character number and searches whether the same character number as the character number of the called terminal is stored in the database 580 (S315).

If there is the same character number as the character number of the called terminal as a result of step S315, the character number converting means 550 selects and converts the terminal number matching the character number of the called terminal stored in the database 580 (S317). ). Subsequently, the text number transmitting means 560 outputs the converted called terminal number and calling terminal number so that a call path is formed between the called terminal and the calling terminal (S319).

Where the character number transmitting means 560 outputs the called terminal number and the calling terminal number in step S319 is a switch in each mobile communication network or PSTN when the called terminal is a mobile communication terminal and a wired terminal.

If there is no character number equal to the character number of the called terminal as a result of step S315, the character number converting means 550 transmits the information that there is no same character number to the PSTN 400 switch (S321). Subsequently, the PSTN 400 exchange transmits an announcement that the call connection is impossible to the wired terminal 200 (S323).
