Center (ShSC) is a Short Message Service Center (210), 210 is a mobile switching center (MSC) / Visitor Location Register (VLR), and 212 is a base station.

In addition, reference numeral 230 is a charge settlement unit for managing charges according to each MP3 file, 240 is a subscriber location register (HLR: Home Location Register) for storing and managing subscriber parameters and location information.

In addition, reference numeral 110 is an MP3 downloading system for delivering a specific MP3 file to the wireless registration system 120 through an X.25 interface or a public data communication network, and 260 applies for searching and downloading MP3 using ARS. Is an ARS server. 220 is a private automatic switchboard (PABX) / voice information system (VMS).

The operation of downloading a specific MP3 file to the mobile communication terminal equipped with the MP3 player through the MP3 downloading system configured as described above is as follows.

First, as shown in FIG. 2, the user of the personal computer 100 attempts to connect to the MDS server 110 to download a predetermined MP3 file to the MDS server 110 through the Internet. The 100 and the MDS server 110 maintain a connection with each other by HTTP, and the user connects to the MDS server 110.

In the connected state, the user of the personal computer 100 registers his or her personal information to the database manager 112 of the MDS server 110 and then requests a download of a specific MP3 file. In this case, the registered personal information includes an ID, a password, a name, an address, an authentication number of a mobile communication terminal, and the like.

Subsequently, the MDS server 110 transmits the MP3 file requested from the personal computer 100 to the wireless registration system 120 through the MDP.

That is, when the user connects to the MDS server 110 through the Internet, the user is connected via HTTP provided to the MDS server 110, and the MDS server 110 and the wireless registration system 120 respectively provide MDPs. It is possible to perform the transfer of MP3 files.

Meanwhile, in addition to the method of transmitting the MP3 file through the Internet as described above, as shown in FIG. 3, the MP3 file may be received using the telephone ARS.

In more detail, first, a user who wants to download an MP3 file accesses the MDS server 110 through the ARS server 260 and the ARS server 260 through a public switched telephone network.

Thereafter, the user searches for an MP3 file in the MDS server 110 using the ARS function and requests a download of a predetermined MP3 file. Accordingly, the MDS server 110 delivers the requested MP3 file to the wireless registration system 120 through an X.25 interface or a public data communication network.

The MP3 user downloads the selected MP3 file to his mobile communication terminal through a base station (BTS) 212 using a wireless auto registration function provided by the wireless registration system 120 and stores / uses it.

On the other hand, when accessing the MDS server 110 to download the MP3 file using the telephone ARS function, the billing unit 230 for each user registered in the visitor location register 210 and subscriber location register 240 According to the settlement function of the billing / management fee according to each MP3 file, and by providing various statistical functions can provide monthly fee statistics, individual MP3 download statistics information.

In addition, when a failure occurs when downloading the MP3 file, a function of delivering the generated failure information to the operator's mobile communication terminal in the form of a short message is also provided.

On the other hand, the packet structure of the above-described MP3 downloading protocol (MDP) has an MDP primitive 1 byte, MDS ID 2 bytes, as shown in FIG. The MDS ID is a code that the MDS provider makes a request for access to the mobile communication provider and is granted, and an authentication code is a code that is given to the mobile communication provider as performing a function corresponding to a password corresponding to the MDS ID.

The size of the header is 8 bytes, and the data area on which the contents of the MP3 file are loaded has 248 bytes.

In addition, since the use of each area in the header is different according to the primitive in the header of the MDP, as shown in the header structure diagram of the MDP primitive of FIG. 5, in the case of the 'CONNECT_RES' primitive, the connection is allowed to the authentication code area. If the packet number is 1 in the 'DATA_SND' primitive, the file name and size are passed to the data area. Each header has a code indicating a connection request (Connect_REQ), a response (Connect_RES), a data transmission (DATA_SAD) and a data transmission completion (DATA_END), a connection release request (RELEASE_REQ), a response (RELEASE_RES), and an error (DATA_ERR). Have

6A and 6B are flowcharts illustrating an interface between the MP3 downloading system and the wireless registration system by the MDP of FIG. 5. In the normal case of FIG. 6A, the MDS server 110 and the wireless registration system 120 are mutually connected. When a connection response is made according to a connection request, data, that is, an MP3 file, is transmitted from the MDS server 110. When the transmission is completed, the wireless registration system 120 makes a connection release request to the MDS server 110, and the connection procedure is terminated according to the release response.

However, in case of abnormality as shown in FIG. 6B, if an error occurs in data transmission after the interconnection as in the normal case, the wireless registration system 120 requests to retransmit from the corresponding packet number in which the error occurs (DATA_ERR), The MDS server 110 receiving the request retransmits the packet number.
