Description

Apparatus and method for using a telephone as a keyboard of a computer terminal {omitted}

The present invention relates to an apparatus and method for using a telephone as a keyboard of a computer terminal, and more particularly, to input data and control data to a computer terminal located in front of a keypad of a telephone to use internet information. It is about data transmission and input.

In general, the operation of a computer terminal device had to have a dedicated keyboard, and unlike a general computer, a mobile phone could use only dedicated content.

However, the provision of such a dedicated keyboard will cause maintenance problems and installation space limitations due to inflow of foreign matters and troubles in use, and the information provided to the mobile phone has a limitation that can be displayed on a limited screen. Problems in diversification will arise.

The present invention makes it possible to easily use a variety of information through the screen of the computer terminal device when using the information, such as the Internet using a telephone to solve the above problems, and breakage of the keyboard that can occur in a public information system, etc. And maintenance troubleshooting.

A first object of the present invention is to enable a telephone to be used as a keyboard of a computer terminal device.

A second object of the present invention is to implement an interface device for a computer terminal using all kinds of portable telephones owned by each.

A third object of the present invention is to provide an interface to an unspecified number of users of a computer device installed in a public place.

To this end, the present invention provides a method for transmitting data to a computer terminal, the method comprising: registering computer terminal devices in a route assignment and a protocol converter, assigning a unique number to a registered computer terminal device to enable manual connection to the phone, or Automatic connection by automatic melody generation so that the terminal in front can be used without a separate input number, and after the step, in the data transmission, the key tone generated from the keypad of the telephone is transmitted to the routing and the protocol converter, and the key tone is transmitted. Convert it to code and configure it into a packet. The keytone sound, which is composed of packets, is transmitted to a computer terminal and converted into a keyboard scan code.

Hereinafter, described in detail by the accompanying drawings as follows.

1 is a diagram showing the overall structure of a telephone as a keyboard of a computer terminal. The key tone sound generated by the telephone 1 is received through the public telephone network 20 to the route assignment and protocol converter 10, and to the route assignment and protocol converter. The received key tone is recognized (3), referred to the terminal address database (8), and then converted into a data code to form a packet. The converted key tone sound data is sent to the code combination and conversion unit 4 of the computer terminal 2 to the Internet network 21. The sent data will work with reference to the key array database 6 and the result will be displayed on the screen 7 for input and control.

Fig. 2 is a flow diagram of registering a computer terminal device with a routing and protocol converter to be preceded in order to be used as a keyboard of the computer terminal device 10 with a telephone. When a computer terminal device having a unique ID is assigned to the route assignment and protocol converter 10 and requests registration (82), in the route assignment and protocol converter, the computer terminal device is turned on at the same time as the registration reception 52 and is ready. Will be set.

FIG. 3 is a flowchart of a manual connection which is a first method for using a computer terminal device registered through FIG.

In order to use a computer terminal device as a telephone, a connection is made (55, 56, 57) to a routing and a protocol converter, and then input 43 is performed using the telephone according to the unique number request 62 of the terminal.

Connection 89 is made with the terminal according to whether the input number matches. The connection message is confirmed through the screen 90 of the telephone 42 and the computer terminal device.

4 is a block diagram of a computer terminal device for automatic connection of FIG.

The key tone input device 110 of the computer terminal is composed of a melody receiving device 112 and a recognition unit 111 for recognizing the received melody, the code combination and conversion unit 4, the phone array data in the computer terminal device The base part 6, the information processing part 5, and the user screen 7 are comprised.

FIG. 5 is a flow chart of an automatic connection which is a second method for using a registered computer terminal through FIG.

In order to use a computer terminal as a telephone, a connection (55, 56, 57) to a routing and protocol changer is then transmitted (58) to the telephone with a melody combination including a check digit in the routing and protocol converter. The transmitted melody is generated by the telephone and is received by the melody receiving panel of the computer terminal to recognize the melody 86. After analyzing the recognized melody and checking the check digit, if it is legal, the identification code 87 is transmitted to the routing and protocol converter. The unique ID of the terminal is identified according to the procedure of identification code information confirmation 59 and connection establishment 89 is made.

6 is a data flow diagram from the telephone to the computer terminal.

After inputting the telephone 44, the routing and the protocol converter receive the keytone sound (66) and transmit the data to the computer terminal through the operation of the received keytone sound (67) and the button code conversion (68). (69). Receiving the transmitted data, the corresponding computer terminal device checks (93) the current mode and refers to the key array database 94 suitable for the mode. The referenced data is converted into a keyboard scancode (95), passed to the operating system of the scancode (96), and the result is output to the screen (97).

7 is a flowchart illustrating a termination of connection between a telephone and a computer terminal in the data flowchart of FIG. 6.

When the call disconnection and connection termination 46 of the phone occurs, the routing and protocol converter detects a loss of carrier 70 to automatically terminate the connection with the phone 71.

After the automatic termination of the phone and the computer terminal to the termination request 72, the connection is terminated (100).

After termination, all parts return to connection wait state 75,101.

As described above, the present invention allows a user to operate the device in a narrow space freely in a narrow space by using the telephone as a keyboard of a computer terminal device, and according to the maintenance and management according to the use of a computer device installed in a public place. Effects can be obtained, and when using information such as the Internet by using a mobile phone, it is possible to obtain an effect that can be easily and easily viewed by using an information search with a general computer device through a screen of a computer terminal device. When the present invention is applied to a computer terminal device, convenience and unity of an input device can be provided.
