## Abstract

There is provided a data communication method using a wireless terminal capable of accessing the Internet. The wireless terminal accesses the Internet, and then sends a data transmission request to a content provider. The wireless terminal provides the content provider with an IP address and associated information of a data terminal to which the data is to be transmitted. The content provider then transmits the data to the data terminal based on the IP address and the associated information. Preferably, the content provider sends a data transmission end message to the wireless terminal after completion of the data transmission.

## Claims

### Claim 1

A method for transmitting data from a content provider, when transmitting is requested by a wireless phone and the data is transmitted to a wireless computer, comprising the steps of:
accessing the content provider via the Internet by the wireless phone;
selecting, by the wireless phone, a file from file information accessed in the content provider;
sending a data transmission request for the selected file from the wireless phone to the content provider;
after sending the data transmission request for the selected file, receiving a destination inquiry message from the content provider at the wireless phone in response to the data transmission request, wherein the destination inquiry message requests an Internet Protocol (IP) address of the wireless computer and associated information, wherein the associated information comprises a password for accessing the wireless computer;
providing the IP address of the wireless computer with the associated information to the content provider from the wireless phone; and
after accessing the wireless computer using the associated information, transmitting data corresponding to the data transmission request for the selected file from the content provider to the wireless computer based on the IP address without transmitting the data to the wireless phone.

### Claim 2 (depends on 1)

The method of claim 1, wherein the content provider sends a data transmission end message to the wireless phone and the wireless computer after completion of the data transmission.

### Claim 3

A method of transmitting data from a content provider, when transmitting is requested by a wireless phone and the data is transmitted to a wireless computer, comprising the steps of:
accessing the content provider via the Internet by the wireless phone;
selecting, by the wireless phone, a file from file information accessed in the content provider;
sending a data transmission request for the selected file from the wireless phone to the content provider;
after sending the data transmission request for the selected file, receiving a destination inquiry message from the content provider at the wireless phone in response to the data transmission request, wherein the destination inquiry message requests an E-mail address of the wireless computer and associated information, wherein the associated information comprises a password for accessing the wireless computer;
providing the E-mail address of the wireless computer with the associated information to the content provider from the wireless phone; and
after accessing the wireless computer using the associated information, transmitting data corresponding to the data transmission request for the selected file from the content provider to the wireless computer based on the E-mail address without transmitting the data to the wireless phone.

### Claim 4 (depends on 3)

The method of claim 3, wherein the content provider sends a data transmission end message to the wireless phone and the wireless computer after completion of the data transmission.

### Claim 5

A data communication system using a wireless terminal, comprising:
a wireless phone for wirelessly accessing a content provider via the Internet, selecting a file from file information accessed in the content provider, sending a data transmission request for the selected file to the content provider, after sending the data transmission request for the selected file, receiving a destination inquiry message from the content provider, and transmitting an Internet Protocol (IP) address of a wireless computer with associated information to the content provider in response to the destination inquiry message, wherein the associated information comprises a password for accessing the wireless computer; and
the content provider for analyzing the data transmission request from the wireless phone, transmitting the destination inquiry message to the wireless phone in response to the data transmission request, wherein the destination inquiry message requests the IP address of the wireless computer and the associated information, and after accessing the wireless computer using the associated information, transmitting data corresponding to the data transmission request to the wireless computer based on the IP address of the wireless computer, without transmitting the data to the wireless phone.

### Claim 6 (depends on 1)

The method of claim 1, wherein the associated information further comprises a user identification (ID) for accessing the wireless computer.

### Claim 7 (depends on 3)

The method of claim 3, wherein the associated information further comprises a user identification (ID) for accessing the wireless computer.

### Claim 8 (depends on 1)

The method of claim 1, wherein the wireless computer is not a printer.

### Claim 9 (depends on 3)

The method of claim 3, wherein the wireless computer is not a printer.

### Claim 10 (depends on 5)

The data communication system of claim 5, wherein the wireless computer is not a printer.

### Claim 11 (depends on 5)

The data communication system of claim 5, wherein the associated information further comprises a user identification (ID) for accessing the wireless computer.
