In addition, the ID phone 10 can be configured to receive a wireless call when not connected to the Internet by adding a wireless call function.

On the other hand, the PC 20 has a terminal for connecting the ID phone 10 and the ID phone program for supporting the function of the ID phone 10 is built in. The connection terminal is preferably a USB (Universal Serial Bus) terminal, it is possible to simultaneously connect a plurality of ID phones 10 using a USB hub, wherein each ID phone 10 is connected to a USB controller (not shown) Available channel is allocated to perform communication. The ID phone 10 operates only when the ID phone program is installed in the PC 20. When the ID phone 10 is connected, the PC 20 drives the program to transmit the unique information and its IP address transmitted from the ID phone 10 to the CGW 50 according to the program.

The CGW 50 manages a database 70 that stores unique information of all ID phones 50, that is, a chip number of the ID phone 10, a phone number, and an IP address of the PC 20. Done. When the ID phone 10 is connected, the CGW 50 performs the authentication procedure for the corresponding ID phone 10 and calls the ID phone 10 when the call is requested from the ID phone 10 that is normally available. Each of the ID phone 10 is notified of each other's IP address to enable communication of each other, the ID phone 10 is transmitted to the Internet based on the IP address to which the other ID phone 10 is connected. do. That is, each ID phone 10 that obtains the IP address of the other party ID phone 10 by the CGW 50 may make a direct call through a router that sets a route based on the IP address in the Internet network.

As shown in FIG. 3, in order to register the ID phone 10 in the Internet telephone system of the present invention, first, the ID phone 10 is connected to the USB terminal of the PC 20 as in step S10. At this time, in step S12, it is determined whether the software for supporting the ID phone 10 is installed. If the software is installed, the process proceeds to step S16, and if the software is not installed, the step ( The process proceeds to S14) and waits for the software to be installed, and then proceeds to step S16 after the software is installed by the user. In step S16, the chip number of the connected ID phone 10, a unique ID (used in the same concept as a commonly used phone number of a PSTN network) and an IP address are transmitted to the CGW 50.

Subsequently, in step S18, the CGW 50 determines whether the ID of the ID phone 10 transmitted in the step S16 is an ID that is not registered. The process proceeds to step S20 to register the reported ID, and then proceeds to step S22. If the ID is registered, the process proceeds to step S22 to change the IP address of the corresponding ID. Here, changing the IP address of the corresponding ID in the step (S22), for example, the ID phone 10 is moved from the first registered position to connect the ID phone 10 to the PC 20 in another area. It is necessary when That is, the ID of the ID phone 10 is fixedly assigned, but the corresponding IP address must be newly changed and registered every time with the IP address of the PC 20 to which the ID phone 10 is currently connected.

Subsequently, in step S24, it is determined whether the CGW 50 is a user who wants to receive the additional information. If the user does not want the additional information, the process proceeds to step S30 and waits for a call. When the user wants to proceed to step S26 to determine whether there is information that was requested by the user. Subsequently, as a result of the determination in step S26, if there is no information to be transmitted, the process proceeds to step S30 to wait for a call, and if there is information to be transmitted, the process proceeds to step S28 and the information desired by the user is transmitted to the corresponding IP address. Will be sent.

On the other hand, Figure 4 is a flow chart for explaining the overall operation of the Internet phone communication method using a mobile phone of the present invention.

As shown in FIG. 4, in step S40, when the user connects the ID phone 10 to the PC 20, the process proceeds to step S42 and the ID phone 10 as described above with reference to FIG. 2. You will be enrolled in.

Subsequently, after the registration of the ID phone 10 is completed normally through the above-described process, the first user inputs the ID (ID phone number) of the second user using the ID phone 10 in step S44. Then, in step S46 the ID phone number of the second user input to the ID phone 10 is converted to the Internet protocol through the software of the PC 20 is transmitted to the CGW (50). At this time, in step S48, the CGW 50 determines whether the ID phone number of the second user is registered. If the ID phone number of the second user is not registered, the process proceeds to step S50, and 1 After delivering the message to the user, the process proceeds to step 66 where it waits for a call.

On the other hand, if it is determined in step S48 that the ID phone number of the second user is registered, the process proceeds to step S52 and attempts to make a call to the ID phone 10 of the second user. Subsequently, in step S54, it is determined whether the second user answers the call. If no answer is received, the process proceeds to step S56 to determine whether the second user has registered the transfer service. . Subsequently, as a result of the determination in step S56, if the second user is registered with the transfer service, the process shifts to step S58, and an existing registered number, for example, a number of another ID phone 10, a PSTN number, or a cellular phone. After setting the path using the number and the like to execute the access control, the process proceeds to step S64, and when the second user does not register the transfer service, the process proceeds to step S60 and a message to the first user, for example, You will be notified that the phone is not connected or leave a voice message. In this case, when the first user leaves a voice message, when the second user is connected, the voice message is automatically delivered to the second user. On the other hand, as a result of the determination in step S56, if the second user has applied for the wireless call service, the process proceeds to step S62 and makes a wireless call to the second user, and then proceeds to step S68.

On the other hand, as a result of the determination in step S54, when the second user receives the call, the process proceeds to step S64 to start a call with the first user. Then, in step S66, when the call is over, the flow advances to step S68 to wait for a call.

The present invention is not limited to the above-described embodiments and can be implemented in various modifications without departing from the spirit of the present invention. That is, in the present invention, since each ID phone has its own unique ID and always shares information with the CGW, it can be implemented to be an improved e-commerce service by using it to solve personal authentication problems in e-commerce. Do. In addition, in the above-described embodiment, the call between the two has been mainly described. However, all information available on the Internet, such as stock, E-mail, search, and road information, can be provided through a server connected to the CGW. The ID phone of the present invention can be used as a general information medium, rather than as a telephone.

As described above, according to the present invention, the ID phone is the size of a general mobile phone, and includes a VoIP function board such as a voice compression chip (DSP) and an external device using a USB terminal, so that any computer capable of carrying the Internet when using it is desired. Can also be connected with. In addition, it is easy to carry and people who do not know a computer can use it as if they plug a telephone into a telephone.

In addition, since the present invention basically uses the Internet as a communication system, if only the Internet is available regardless of the distance, voice calls can be made internationally without any additional investment. The advantage is that you can only use the ID phone number.
