The present invention relates to a USB-type portable Internet phone with a T-money function, which is a prepaid electronic money, and more specifically, a prepaid type for USB memory and payment in a portable Internet phone. The present invention relates to a USB-type portable Internet phone which is equipped with a prepaid electronic money function that provides simultaneous use of T-money, which is electronic money.

As is well known, since the Internet phone uses the Internet network instead of the PSTN, the international phone has the advantage that 50% to 80% of the current rate is inexpensive, and many domestic and foreign companies are entering the market. This is expected to grow rapidly due to the rapid growth of the Internet and technological developments to support or replace telephone services such as PSTN.

In particular, with the approval of the government's Internet telephony business in July 2005, the spread of USB-type Internet phones using the Internet is expected to expand rapidly. The USB-type Internet phone is expected to be provided with a prepaid recharging method that uses a prepaid billing and a predetermined amount of prepaid charges from the basic charging method of the conventional postpaid billing method.

Such a telephone function system via the Internet is developed in accordance with a user's needs and a carrier's needs in the form of a soft-phone or a hardware-phone using USB.

1 shows a configuration diagram of the above-described USB type Internet phone.

As shown, the Internet phone 1 has a USB terminal 10 connected to a USB host, a USB hub 12 connected to the USB terminal 10, a memory controller 14 for storing data, and a flash memory ( 16) and a melody generating unit 20 for generating a melody to output a sound range of a predetermined frequency band to a buzzer 22 together with an audio IC chip 18 for providing an Internet telephone function.

The function of the Internet phone 1 is to connect the Internet phone 1 to a USB port of a PC that can access the Internet, and then install a program that can use the Internet phone. To provide.

At this time, the overall control of the Internet phone 1 is executed by the audio IC chip 18, the memory control unit 14 to download the data from the PC to store in the flash memory 16 and read it again (Read) To provide.

On the other hand, in recent years, a fare payment means using RFID (Radio Frequency Identification) has been applied to a credit card and a mobile terminal, and is operating as various kinds of offline public fare payment means.

T-money, which is currently used as such a fare payment method, is a representative prepaid electronic money used as a means of bus, transportation, and small-scale payments throughout Seoul and the metropolitan area.

The USB memory unit; A flash memory connected to a USB hub and a USB port and storing data by a memory controller, wherein the Internet phone module unit is provided; An audio IC chip connected to the USB hub to control overall telephone functions through the Internet, and a microphone for receiving a user voice and a speaker for outputting the other party's voice and a buzzer by the audio IC chip. A melody generating unit for generating a melody to output the sound range of the frequency band is provided, The billing module unit; A smart card reader unit sequentially connected to the USB hub, a smart card IC chip connected to the smart card reader unit and controlling the billing, charging function, and information inquiry function as a whole, according to the control of the smart card IC chip. An antenna for transmitting and receiving data in contact with the RF terminal; It is characterized by.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 3 is a block diagram of a portable Internet phone of the USB type with a built-in T-money function according to an embodiment of the present invention.

As shown in the drawing, a USB terminal 102 connected to a USB host, a USB hub 104 connected to the USB terminal 102 and a USB cable, and a USB hub 104 connected to the USB hub 104 to store predetermined data, and an Internet phone A USB memory unit, an Internet phone module unit, and an electronic money (T-money) module unit are provided to provide a function and a function such as billing in contact with the RF terminal.

The USB memory unit includes a flash memory 108 in which data is stored by the memory controller 106 connected to the USB hub 104.

The Internet phone module unit, the audio IC chip 126 for controlling the overall telephone function over the Internet is connected to the USB hub 104, the microphone 142 receives the user voice to the audio IC chip 126 and Speaker 140 for outputting the other party's voice is connected. In addition, the audio IC chip 126 is configured to be connected to a buzzer 132 having a built-in oscillation circuit and outputting a sound range of a predetermined frequency band of the melody by controlling the melody generating unit 130.

The electronic money (T-money) module unit is connected to the smart card reader unit 110, the smart card reader unit 110 and sequentially connected to the USB hub 104, smart card for controlling the T-money function as a whole The IC chip 112 and the smart card IC chip 112 is controlled by an antenna 114 in contact with an external RF terminal for transmitting and receiving data.

Next, the operation of the present invention will be described with reference to FIG.

First, the portable Internet phone 100 of the USB type with a prepaid electronic money function of the present invention is a USB memory unit, Internet phone module unit, electronic money (T-money) module unit connected to the USB hub 104 Each function is performed, and the function according to this will be described separately.

First, the functions of the USB memory section will be described.

When the USB terminal 102 provided in the portable Internet phone 100 of the present invention is connected to a USB port of a personal PC or a general portable terminal using a USB cable, a personal PC or a general portable device according to the connection of the USB terminal 102. The terminal recognizes this.

Then, when selecting data to be stored through a personal PC or a general portable terminal according to a series of known techniques, the selected data is transmitted to the USB hub 104 of the present invention through a USB cable, the memory control unit 106 ) Transfers data received from the USB hub 104 to the flash memory 108 via the data bus and stores the data.

In addition, in order to read data stored in the flash memory 108, the stored data is read by controlling the flash memory 108 while being connected to a personal PC or a general portable terminal.

Secondly, an internet phone call function will be described through the Internet phone module unit.

As described above, the portable Internet phone 100 of the present invention is connected to a USB port such as a personal PC.

The portable Internet phone 100 must have a predetermined program installed to provide an Internet phone function. Since the program is automatically downloaded from the corresponding Internet site every time it is connected to a personal PC, it is possible to download a program that can easily use the Internet telephony function even if data upgrade occurs.

In such a state, when the portable Internet phone 100 is connected, the personal PC switches to the standby mode in which the Internet phone function can be used. Thereafter, the user can make a phone call over the Internet with the other party after confirming the user authentication according to the operation of the Internet using program.
