Description

The present invention relates to an IP telephone communication technology, and more particularly to a communication dial-up connection apparatus for IP telephone users of a mixed character type account that performs dial-up connection with a conventional telephone.

The IP telephone technology is a communication technology for making a telephone call through computer operation and the Internet (Internet), and it is possible to prepare a broadband network environment for both individual users and corporate users, and only to install a gateway on a user terminal. It was possible to communicate by calling from a broadband network.

In the IP telephone technology, an analog voice signal is compressed into a digital code, and then immediately transmitted by voice on a network base in a point-to-point manner. By using the Internet, not only can the voice transmission service be provided immediately, but also anywhere in the world, even if the user does not use a public telephone network (PSTN, that is, a conventional conventional telephone line), a call can be made over a long distance telephone. Became possible. With the spread of the broadband Internet, it is expected that voice communication will be made using the Internet in the future.

A general IP phone user account is composed of a mixture of alphabets, symbols, and numbers for user identification. When a user dials up and calls the other party, the other party must be selected by a computer at a fixed location to achieve the communication purpose. Therefore, each time a dial-up connection is made and called, a procedure of selecting a dial-up program at the computer terminal is required. In this way, the method of making a dial-up selection on a computer with a fixed location has to interrupt the operation if there are other people using the computer, which not only hinders the operation, Since the operation is inconvenient and has various limitations, a person who is unfamiliar with computer operation has been forced to make considerable efforts, and therefore has to be improved.

A first object of the invention of the present application made to achieve the above object is to provide a communication dial-up connection device that is a conventional telephone and is dial-up connected to an IP telephone of a character type mixed user account. By converting the number code assigned in advance and using the numeric keypad of a conventional telephone to connect to the call destination of the character type mixed user account by dial-up method, the trouble of calling the other party with a computer at a fixed place The gist of the present invention is that it is a dial-up connection device that can be omitted.

Another object of the invention of the present application is that when a user calls a destination, the calling code is converted into a character type mixed code in advance and is displayed on the display in a parallel manner so that the calling destination can be identified. The gist of the present invention is that it is a dial-up connection device characterized by facilitating the above.

Yet another object of the present invention is to provide a function to automatically record and save a user account, and to convert, connect and call by providing a function for creating and searching a telephone directory by itself. The gist of this is a dial-up connection device. When the user first dials up the destination account based on the rules of the character and number conversion table, this account is converted to a mixed character account code, which becomes a telegraph code pressed on the phone keyboard, and the memory This is recorded in the apparatus, and when the user calls again, the user can be directly called with the search key of the apparatus. On the contrary, when this device is in the reception mode, the microprocessor displays the numeric code and the character type mixed code after conversion through the sound effect processing circuit on the display in parallel, and is recorded and stored in the memory device. Calling is convenient for the user using this apparatus.

An object of the present invention is to provide a communication dial-up connection device for dial-up connection to an IP telephone of a mixed character user account using a conventional telephone, which is converted into a numeric code assigned in advance, and a numeric keypad of the conventional telephone. By connecting to the call destination of the mixed character type user account using the dial-up method, it is possible to save the trouble of calling the other party with a computer at a predetermined location.

According to the present invention, a telephone number (0 --- 9 ##, etc.) for dial-up connection is identified, converted into a numeric code assigned in advance by the microprocessor again, and then the received telephone code is actually called. The account is converted into an account, and further transmitted to a computer through a transmission line connected through a sound effect processing circuit, and a communication request for calling a remote IP telephone user is completed.

Under the control of the microprocessor MCU, the display displays data such as character codes and numeric combination codes, user account codes, and user account numeric codes, and information can be controlled by visual operation.

<Explanation of device operation>
<Calling and telephone dialing mode>
When a user dials a user of an IP telephone terminal for the first time, when the user first converts the character code into a corresponding digital code, the user can directly connect with the keyboard of a conventional telephone. (The comparison table is as shown in FIG. 3)

If the user account of the destination computer that wants to make a call is tone 5978, the corresponding digital codes are 20151405 and 5978, the user holds the handset, presses * 20151405 * 5978, dials up, the decode circuit receives, After decoding, it is transmitted to the microprocessor.

After receiving this telegraph code, the microprocessor identifies the number between the two * telegraph codes and converts it to a character code. * 20151405 * is converted to tone, 5978 is added, and it is received with a telegraph code of * 20151405 * 5978 and displayed on the LCD screen. Next, the converted tone 5978 account is transmitted to the computer through the sound effect processing circuit, and the relay RY is driven to operate the relay to connect to the coupling circuit to form a call, thereby completing the calling program.

<Device mode selection>
If the user connects to a user account on the computer, the user can check the user account using the UP or DN edit key if it has been saved in the memory of the device.

The LCD display displays user accounts in the memory one by one with an edit key. When a user to be called is selected and the DA key is pressed, the microprocessor immediately transmits to the computer through the sound effect processing circuit of the user account, and the call is completed. At the same time, a ringing tone that can be heard from the SP is sent, so the user only has to lift the handset and wait for the other party's response.

When the call ends and the user hangs up, the call detection circuit current is interrupted and drops to HK potential, the microprocessor releases the relay, disconnects the coupling circuit and completes the disconnection program.

<Reception response>
When a call is received from a remote computer user, the USB receives the transmission information of the computer, notifies the microprocessor from the sound effect processor, and the microprocessor sends the received user account to the LCD for display. Is displayed in place of a telephone code that can be called by telephone.

The microprocessor drives the RN and FZ to the bell generator, sends the bell oscillation signal to the Tip and Ring terminals, generates a bell sound on the telephone, and when the user lifts the handset, the utterance detector operates and the microprocessor The stop of the bell is notified, and the microprocessor drives the relay RY to operate the relay and connects to the coupling circuit to form a call. When the call ends and the user hangs up, the call detection circuit current is interrupted and drops to HK potential, the microprocessor releases the relay, disconnects the coupling circuit, and completes the disconnection program.

<Save and edit user account>
The user can save the calling user account in the memory device, and after selecting the required user account with the edit key, the user can press the STO key to save this account in the phone book. You can also delete your account.

The user can also save the user account in the memory device in advance using the telephone. For example, if the ken-3349 account is stored in the memory device in advance (the user is not called), and the contrasted data is 11051427 and 3349, When the user lifts the handset and presses # 20151405 # 3349, the user dials up, and after decoding by the decoding circuit, it is sent to the microprocessor.

After receiving this telegraph code, the microprocessor identifies the number between the two # telegraph codes and converts it to a character code. # 11051427 # is converted to ken-, and 3349 is added, and it is received with a telegraph code of # 11051427 # 3349, displayed on the LCD screen, and a sound that can be heard by the SP is sent when saving is completed.

When the microprocessor knows that the first character of the received telegraph code starts with #, it does not execute the calling program of the computer terminal, and conversely, after sending the save completion voice, saves the other user account After the user hangs up, the system returns to the standby state.
