A method is provided for downloading an MP3 file to an MP3 player using a mobile phone.

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

1 is a block diagram of a system for downloading MP3 files to an MP3 player using a mobile phone according to a preferred embodiment of the present invention.

The system shown in FIG. 1 includes an MP3 player 10, an interface device 11, a mobile phone 12, a telephone repeater 14, and an MP3 file holding and supplier 16.

When the system requests the MP3 file holder and supplier 16 to transfer the file in MP3 format, the MP3 file holder and supplier 16 access the corresponding MP3 file stored in the telephone repeater. The mobile phone 12 transmits the received MP3 file to the MP3 player 10 after the received MP3 file is stored.

The MP3 file holder and supplier 16 stores various types of files in MP3 format, including MP3 music files, including commercial language materials, daily weather forecasts, yearly transport, children's stories, and stock quotes. Then, in response to the MP3 file transfer request from the mobile phone 12, first, menu data for selecting a desired file from among the stored MP3 files is transmitted to the mobile phone 12. Then, the MP3 file is transmitted to the mobile phone 12 on the basis of the menu data selected by the user transmitted from the mobile phone 12. MP3 file holder and supplier (16) is a company that holds the copyright for the sale and distribution of MP3 files, establishes a vast amount of database, accesses MP3 files requested by mobile phone (12), and repeaters Transmit via 14. When transferring any one MP3 file, in consideration of the memory capacity built into the mobile phone 12, it is preferable to transmit by dividing by a certain size. The amount of data to be divided is determined according to a communication protocol previously agreed between the mobile phone 12 and the MP3 file holding and supplier 16. Of course, it depends on the memory capacity built into the mobile phone (12).

The mobile phone 12 requests the MP3 file holding and the supplier 16 to transfer the MP3 file, and holds the MP3 file selected by the user based on the transferred menu data (displayed on the mobile phone). Transfer to supplier 16.

Examples of menu data displayed on the LCD window of the cellular phone 120 are shown in Figs. 2A and 2B.

If the user selects " 2.MP3 music genre division " in Fig. 2A, the screen of the mobile phone 12 changes as shown in Fig. 2B. Here, the user selects a desired song while continuously moving to a sub group. The selected menu data is sent through the telephone repeater 14 to the MP3 file holder and supplier 16.

Thereafter, the MP3 file is stored and stored in the memory embedded in the mobile phone 12, and the MP3 file transmitted from the supplier 16 is downloaded to the MP3 player 10 through the interface device 11. Even in the case of downloading, a communication protocol suitable for a specific interface device between the mobile phone 12 and the MP3 player 10 should be pre-determined, which may be determined in consultation with the MP3 player manufacturer. That is, even in this case, since the MP3 file received by the mobile phone 12 is received in a predetermined size, the mobile phone 12 and the MP3 player manufacturer should be negotiated to rearrange them in the same order as the original file. .

Then, the MP3 player 10 can download and play the MP3 file.

Meanwhile, the interface device 11 may use a universal serial bus port (USB port), a parallel port, a COM port, and the like.

When using the USB port, a specific connector is required to match the USB port to the currently available external connector along with modifications to the operating software to support the USB port on the mobile phone. Since the current trend introduces a lot of USB port as an interface with an external device, it is preferable to use it in the interface device of the present invention.

The parallel port is currently used for applications requiring relatively high speed, such as for printers, but can be used for downloading from the mobile phone 12 to the MP3 player 10.

Since the COM port is currently used for the interface between the PCS phone and the Internet, the mobile phone 12 can be used for the interface device only by changing the software to support the COM port. However, when using a COM port, the download speed is somewhat slower than other methods.

On the other hand, the user pays the MP3 file holding and supplier 16 in exchange for receiving the MP3 file using the mobile phone 12, it is convenient to include in the telephone bill.

3 is a flowchart for explaining a method for downloading an MP3 file to an MP3 player using a mobile phone in the system shown in FIG.

The mobile phone 12 attempts to connect to the provider 16 via the telephone repeater 14 and retains the MP3 file (step 302).

The MP3 file holder and supplier 16 transmits to the mobile phone 12 menu data that allows the user to select the MP3 file to the mobile phone 12 (step 304).

When the menu data is transmitted to the mobile phone 12, the mobile phone 12 user views the menu data and selects the desired song, and the selected MP3 file is retained and supplied to the MP3 file through the telephone repeater 14 and the supplier 16. Is sent to.

The MP3 file holder and supplier 16 transmits some MP3 file data to the mobile phone 12 based on the menu data transmitted from the mobile phone 12 (step 308), where the transferring of some data is MP3. Because of the large file size, sending it over the air may require retransmission due to an unexpected error in the transmitted data, so it will only send a predetermined amount with the MP3 file retention and vendor (16).

The mobile phone 12 receives some data, stores it in the built-in memory, and checks its validity (step 310).

It is determined whether the transmitted data is valid (step 312), and if the data is not valid, the MP3 file is retained and the supplier 16 requests retransmission (step 314).

If the data is valid, the data stored in the mobile phone 12 is downloaded to the MP3 player 10 through the interface device (step 316).

It is determined whether the transfer is completed (step 318). That is, some transfer, validity check, and download of one MP3 file are repeatedly performed on the entire MP3 file.

When downloading of one file is finished, the connection is terminated or a request for transmission of another MP3 file is performed (step 320).

With the above process, you can download MP3 files conveniently and quickly.

The present invention is not limited to the above-described embodiments, and of course, modifications can be made by those skilled in the art without departing from the spirit of the present invention. That is, in the embodiment of the present invention, the MP3 file to be transmitted is divided into a predetermined size and transmitted. However, as the future communication technology and memory capacity are minimized, the entire MP file may be transmitted at once. In addition, the transferred MP3 files can be downloaded directly to the MP3 player without storing them in the mobile phone.

Therefore, the scope of the claims in the present invention will not be defined within the scope of the detailed description, but will be limited to the claims below.

According to the present invention, by requesting the transfer of the MP3 file to the company having a variety of content files in the MP3 format, including the MP3 music file using a mobile phone, and by downloading the transferred MP3 file to the MP3 player, Has an effect.

First, since MP3 files are transmitted through a universal mobile phone, you can quickly download and listen to any file you want anywhere. Since it is downloaded using a telephone network without using a computer or the Internet, people outside the computer can listen to MP3 format files conveniently.

In fact, it was difficult to obtain MP3 files until now, but sales of MP3 players were sluggish. However, according to this system, it is easy to download MP3 files, which can additionally accelerate the sales of MP3 players.

In addition to the MP3 music files, you can download various types of files in MP3 format such as commercial language materials, daily weather forecasts, yearly transport, children's fairy tales, stock quotes, etc. .

On the other hand, the cost of the downloaded MP3 file can be included in the user's telephone bill, so that you can conveniently pay.
