Abstract

PURPOSE: An information inputting method using a DTMF(Dual Tone Multi Frequency) of a terminal is provided to allow a user to send a voice mail as an E-mail by processing characters and numbers with a general phone. CONSTITUTION: DTMF information corresponding to character or numeral information is inputted(51). That is, characters and numerals are combined and inputted by using a key board of a phone terminal. Different DTMFs are inputted for each numeral and special signs, and each character is inputted according to the number of outputs of DTMF over the numeral. And then, the DTMF combination according to the number of key board inputs is analyzed(52). That is, the information on each numeral can be obtained by analyzing the DTMF information as it is, while the character information is obtained by checking how many DTMF information have been outputted for the numeral.

Description

Information input method using DMF of terminal {Method for inputting information using DTMF of terminal}

The present invention relates to a method for inputting information in a system using a public telephone network (PSTN), and more particularly, using a DTMF of a terminal for inputting information such as an e-mail address by using a DTMF (Dual Tone Multi Frequency) of a telephone terminal. It is about information input method.

More specifically, the present invention is to configure the high frequency and low frequency DTMF information for numbers or letters on the phone's keyboard in three combinations, in order for the user to input text information into the phone terminal. Information indicating whether the letter is lowercase or lowercase; the second is information indicating the number of numeric keys in an input number unit having character information to be input; and the third is information on which position in the character group on the numeric keys is located. It's about how to enter information in a combination that tells you.

In the method of inputting information to the telephone terminal as described above, there has been a conventional method of using data communication such as SMS (Short Message Service), but without using separate data communication, purely using DTMF tones, e-mail address, etc. There was no way to enter.

The present invention proposes a method for inputting information such as an English letter into a telephone terminal in a certain order by using DTMF for letters and numbers configured in the telephone terminal.

Therefore, DTMF information inputted by being combined in a predetermined order can be analyzed.

The information input method using the DTMF of the terminal of the present invention comprises a telephone terminal for inputting a combination of DTMF for inputting character information, a public telephone network (PSTN) to which the combined DTMF is transmitted, and the combined and transmitted character information. In the system consisting of a network operator service device for converting the characters into characters, comprising the steps of configuring a new character or numeric information used for e-mail on the keyboard and combining DTMF information; And analyzing the output information of the input DTMF.

Other objects and features of the present invention will become apparent from the detailed description of the embodiments with reference to the accompanying drawings.

Hereinafter, an information input method according to the present invention will be described with reference to the accompanying drawings.

1 is a schematic block diagram showing input of information through a public telephone network (PSTN) in the present invention.

As shown in the figure, a telephone terminal 11 for combining and inputting DTMF for text information input, a public telephone network (PSTN) 12 through which the combined DTMF is transmitted, and the combined text information is analyzed. Network operator service device 13 for converting into text.

The network service provider apparatus is composed of an interactive voice response (IVR) or a voice messaging system (VMS).

2 is a frequency array of a typical DTMF.

A pair of high and low frequencies is formed for each number and letter on the keypad of the telephone.

3 is a DTMF keyboard of a conventional general telephone terminal.

In order to input text using DTMF of pure telephone terminal without any device for data communication in public telephone network, it is possible to use DTMF numbers (0-9) and special keys (*, #) in the drawing. Although it is possible, information such as an e-mail address cannot be input as in the present invention.

FIG. 4 is a diagram illustrating a new keyboard including additional new special characters (@, Q, Z, _, etc.) on the phone keyboard of FIG. 3.

Therefore, when the user inputs a character to the DTMF combination through the telephone terminal (11 of FIG. 1), the network service provider (13 of FIG. 1) analyzes the input DTMF combination and recognizes the corresponding character.

Hereinafter, the operation of the present invention configured as described above will be described with reference to FIG.

The combination of non-numeric characters consists of three DTMFs.

The first digit is used as a character input and case sensitive. English uppercase letters begin with DTMF '*', and English lowercase letters begin with DTMF '#'.

The second digit represents the DTMF number with the desired alphabetic characters.

For example, the letter 'B' is in DTMF '2', so enter '2'.

The third digit indicates the number of desired alphabetic characters in the DTMF.

For example, type '2' because the letter 'B' is the second after DT in '2', after 'A'.

The input information is converted into the high frequency and low frequency forms of the DTMF of FIG. 2 and output to the network subscriber equipment.

As an example in which the inputted information is combined, the letter 'B' is represented as DTMF "* 11", and the letter 'b' is represented as DTMF "# 11".

In addition, the character '@' may be represented as DTMF "* 01" or "# 01".

If an email address like "Addr123@mail.co.kr" is "* 21 # 31 # 31 # 72 1 2 3 * 01 # 61 # 21 # 43 # 53 * 11 # 23 # 63 * 11 # 52 # 72" Can be represented as:

5 is a flowchart illustrating a process of inputting, analyzing, and outputting information.

Enter DTMF information corresponding to character or numeric information. (Step 51).

That is, a combination is input using a telephone terminal keyboard, each number and a special symbol are input different DTMF, and each character is input by the number of times of DTMF output for the number.

Then, the combination of DTMF by the keyboard input frequency is analyzed. (Step 52).

That is, the information on each number may be analyzed as it is input DTMF information, but the character information is analyzed by determining how many times the DTMF information for the number is output by the combined input information.

As described above, the present invention relates to a method of setting a special key on a telephone terminal and inputting text information into a network operator service apparatus through a predetermined combination method.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments.

Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

According to the information input method of the present invention, since a public telephone system can process not only numbers but also characters with a general telephone, an e-mail address can be input, so that voice mail can be sent by e-mail and applied to other necessary services such as text. can do.
