Method for retransmitting mms message and apparatus therefor

A method for re-transmitting an MMS message and an apparatus thereof are provided to meet individuals' satisfaction to a mobile communication service by preferentially processing a person-to-person MMS message over MMS messages transmitted in large quantities. A supplementary service device create an MMS message to be sent in large quantities(S901) and transmits the message to an MMSC(Multimedia Messaging Service Center) by way of the Internet(S903). The MMSC determines whether a current time is before an expiry time(S905). When the current time is before the expiry time, the MMSC transmits the corresponding MMS message to a recipient terminal(S907). If the expiry time has lapsed, the MMSC discards the corresponding MMS message(S909), and transmits a report message including information on the discarded MMS message to the supplementary service device(S911). The supplementary service device re-creates an MMS message with reference to a message ID and recipient information included in the report message(S913), resets an expiry time in the re-created MMS message, and transmits it to the MMSC(S915).
