At this time, the multimedia content request message includes unique identifier (ID) information of the multimedia content or additional information for recognizing the multimedia content.

The MMS server 120 checks the unique identifier (ID) of the multimedia content to be retransmitted according to the request of the transmitting terminal M2 (S411), and determines whether retransmission is possible (S412).

According to FIG. 2A or 2B, it is assumed that retransmission of the unique identifier (ID) 1 digit is indicated as 1 when retransmission is possible and '0' when retransmission is not possible, and the MMS server 120 retransmits. If the possible digit is '0', it is determined that retransmission is impossible and the retransmission impossible message is notified to the transmitting terminal M2 (413).

On the other hand, if the digit of whether retransmission is '1', the MMS server 120 determines whether the multimedia content is paid or free to determine whether to charge the sending terminal M2 requesting retransmission and the web server providing the content. It is determined by checking 1 digit recorded in the 'Division' field (414).

If the digit is displayed as '1' in the case of paying and the digit is displayed as '0' in the case of free, the MMS server 120 requests the retransmission of the multimedia content if the digit is charged as '1'. Notifies the transmitting terminal M2 that charging is added to the content, and receives a response thereto. At this time, if the response from the transmitting terminal (M2) is the multimedia content retransmission confirmation, MMS server 120 generates a charging log based on the charging policy (415). In addition, the MMS server 120 notifies the reception of the multimedia content to be received by the reception terminal M1 and requests the reception of the content (S416).
