Description

Text Transceivers and Portable Text Transceivers for Phones

The present invention relates to an apparatus for transmitting and receiving text using a telephone, and in particular, by inputting text using a dialing button of an existing telephone to transmit a tone signal and decoding the tone signal to display the received text, It is to make it possible.

Ordinary telephones are used as a means for transmitting voice, and various service functions other than voice calls are required. The present invention relates to a text transmitting / receiving apparatus for realizing a text communication using an existing telephone. The built-in device, and to facilitate the input of Hangul, and to make it easy to input Hangul on the phone without the Hangul notation.

In general, the phone character input technique is rarely counted as a finger in the world. The most representative telephone character input techniques are service [700] in the United States and service [144 (tentative)] in Korea Telecom. [700] service is a method of calling the company by pressing the company name by pressing the number 700, and the letters A, B, C, etc. written on the number button of the phone. This is a memorization technique where a service provider receives a company name from a user and combines it with a corresponding number and pre-registers it in a related system. For example, if you press the name of the company, such as Lovelove (love love) to the number [56835683] that corresponds to the alphabet of the license plate, the related system interprets it as the representative phone number of the company to make a call.

KT's [144] telephone number search service is a breakthrough technique that provides services by recognizing almost all Korean characters. However, the complexity of pressing the button twice on the consonants or vowels and the English and signs have the disadvantage that the input is not possible.

The telephone number character input method is evaluated as a core of telemarketing, and is widely used for reservation, order management, customer management, promotion, and sales of companies using the telephone.

1 is a layout of a conventional Korean alphabet input keyboard, which uses the principle of the adjacent button combination Korean code, and was developed by KT and registered in the national standard method.

The method of inputting Hangul characters by using the Hangul character input keyboard according to FIG. 1, for example, presses the [8] button closest to the initial [ㅎ] to press the phone number of 'Hong Gil-dong' Press button [7] to enter [ㅎ]. In the same way, press buttons [5] and [6] in order to enter Neutral [ㅗ], and then press buttons [5] and [4] in order. Press to enter the finality [ㅇ]. In order to input [d], the closest [2] button and its diagonal [4] button are pressed. That is, to input Hong Gil-dong, it is necessary to press [87 56 54 12 89 24 15 56 54].

When the service is provided by inputting Korean characters in this way, the existing 114 guide service can be easily guided according to this method or even if you do not know the phone number, you can make a call automatically if you enter the company name correctly. In addition, guidance services such as announcement of successful applicants, MIA book loan information, stock quotes, etc., can be easily provided by inputting text into a telephone. In addition, it is also possible to easily provide a home automation service for sending a message to the other party's wireless pager or operate the home appliances.

Using the text input method as described above, it is possible to provide a variety of services other than a simple voice call.

However, in order to enter text using the number buttons on the phone, it is possible to enter the text only when the button is written on the button of the phone. Therefore, even if a text input service is provided, the text must be written on the existing phone button or replaced with a newly printed dial. Therefore, the cost burden becomes very large, and the conventional method has a very complicated disadvantage of inputting Korean characters.

In addition, the Hangul character input service as described above can receive the service provided in the relevant communication network, but it was impossible to communicate between individuals.
