USB memory type terminal that functions as a device, and an internet telephone system using the same, and a method thereof, which is easy to install by using USB, and can store data and internet telephone software as a USB memory type. Automated execution of Internet telephony software and storage of user information and call information in its own memory. Video / voice USB Memory for enhanced user information protection and security. A communication system for transmitting voice and video in the form of IP packets.

The USB Memory Internet phone terminal system of the present invention for this purpose includes a PC for access processing on the Internet network; USB Memory for storing general data and embedded software for Internet telephony; USB Soundcard for voice processing; USB Hub to distribute USB Soundcard and Memory; Hub Contoller with CD-Rom Convertor function for autorun; It consists of Headset for voice reception and transmission.

And the call system of the present invention receives the login of the terminal, serves as an H.323 gateway to help communication between the terminal and the VoIP gateway, Call Server for managing the login information; A user DB having user information of a call server; VoIP GW responsible for making calls to the PSTN; GK to manage calls between Call Server and VoIP GW; It consists of a DB that stores GK information.

Therefore, according to the present invention, the USB Memory Internet Phone can be used as a data storage device as well as providing a high quality Internet-based voice call even if a computer does not have a sound card. It can be used automatically without the complicated procedure, and there is no log or usage information left on the PC, so user's information protection and security is easy.

In addition, the system does not use H.323, but by sending voice to the packet using TCP / IP, it is possible to solve the problem of sharing period with H.323 and use in private IP and firewall.

The present invention relates to an internet telephony communication technology and a terminal, and in particular, by carrying a USB memory terminal carrying a terminal connected to a PC to use the data storage function of the USB memory and by storing a program necessary for Internet video and voice communication in the USB memory There is no need to download and install additional software, and by using unique packets using TCP / IP for call between devices and call between device and call server without using web login method and H.323, regardless of firewall or private IP Anyone can easily access video and voice calls using the Internet by connecting a USB to a PC capable of surfing the web, and save user information and call information in a USB memory to protect and secure user information. It is about.

Internet phone is a field of increasing interest and subscribers in the world due to the low cost of voice call and increase of additional services along with the increase of internet infrastructure. It is divided into standalone internet phone and PC-based internet phone. Internet phones are divided into serial phones and USB phones.

The standalone internet phone has a phone type independent internet interface and OS, which allows voice and video calls and various additional services by directly accessing the Internet. The quality of the service is high, but the cost is high and the installation is cumbersome. have.

PC-based serial phones use PC's serial port, which has advantages of call and system stability by port stability, but many PCs do not have a serial port. There is a problem with inconvenience and popularity because it is not.

Since PC-based USB phones need to install a driver for the keypad part, the software must be installed on the PC. Therefore, users who are inexperienced on the Internet cannot use it, and the user's information remains on the PC. And vulnerable to security.

In addition, the service for the existing H.323 terminal in the service system is difficult to use in private IP and firewall due to the modulation and blocking of H.323 information of the IP router.

The present invention provides a data storage function to the user by configuring the Internet terminal in the form of a USB memory to solve the above problems, and at the same time the driver or software built-in itself and the CD-ROM using the CD-Rom Convertor function CD- It has the function to automatically recognize the program at the initial stage as Rom, so it can be used directly by USB connection from any PC without the need of downloading or installing software using CD-Rom. By saving the information in its own USB memory, there is no log or user information left on the connected PC, which solves the problem of user information protection and security.

And the communication between terminals does not use H.323 by TCP / IP, and the communication between terminal and PSTN (general phone, mobile phone) and other H.323 terminal is made by Call Server acting as H.323 gateway. It solves the problem of H.323 and sharing period.

Accordingly, the present invention is based on the connection to a PC using a USB USB connector and USB Memory for data storage, USB Soundcard for the transmission and reception of voice during calls, the internal configuration of the terminal using a USB Hub for USB distribution Characterized in that.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

Figure 1 is a block diagram showing a USB Memory Internet phone of the present invention.

1, a USB connector 12 for connecting with a PC 11 connected to the Internet; A USB Hub Controller 14 for connecting a USB Soundcard 15 and a USB Memory 18; A disk controller 17 for a mobile disk function; A USB memory 18 for storing data; It is characterized by consisting of a USB soundcard (15) and a head phene set (19) for transmitting and receiving voice.

Fig. 2 shows a call terminal device in an internet communication network according to an embodiment of the present invention. A USB memory internet phone 24 is connected to a PC 11 and a call server (Internet) of the PC 11 is used. 21) Log in, transmit voice through packet through TCP / IP communication with Call Server, and do not need to use DSP chip by using unique codec without using H.323 in this process. You can solve the problem of the router related to. The Call Server 21 authenticates the user login using the User DB 22 and performs the H.323 GW role for communication with the VoIP GW 26. By using the login method of Web login, it can be used on any PC capable of web surfing.

3 is a flowchart showing the automatic execution of the USB memory Internet phone of the present invention and the authentication process from the call server. After connecting the USB (A01), the PC recognizes the USB removable disk (A02) and the soundcard (A03). Convert the USB removable disk to CD-Rom for a while (A04) and automatically run the update program using the auto-run function of the CD-Rom (A05), and the update program checks the version information on the call server (A06). Automatically download the new version of the program (A13) and then update the program to run the Internet (A08) .In the first use, enter the login information (A14). Log in (A10) is characterized in that.

4 is a flowchart illustrating a process of making a call using the USB memory internet phone and the system of the present invention, and shows a flow of a call after Log in described in FIG. 3. If you enter the other party's phone number (including wired, wireless, and Internet phone numbers) while the log in is completed (B01) (B02), the Call Server will determine whether you are using the same USB Memory Internet phone user (B03), If it is an Internet phone user number, once more, check the user's Lon in (B04) and send the call (B05). If not, log in (B07 / D01). Call forwarding to the registered number (D03) .If you are not a user of the same USB Memory Internet phone (B06 / C01), check whether or not Prefix is registered with GK (C02) and send the call to GW. It is characterized by (C03).

As described above, according to the present invention, the USB Memory Internet Phone is simple to install and can be manufactured in the form of USB Memory, thereby enabling the popularization of the Internet Phone with the mobility that the existing Internet Phone could not have, and when the prepaid method is applied By eliminating access costs, the prepaid card market can be replaced by a cheaper form and provided to consumers.

In addition, by running the software in the USB memory without installing it on the PC, the user information and call information remain only in the USB memory, thereby maximizing the user's information protection and security effects.
