Abstract:
1. A Multimedia Messaging Service (MMS) system, the MMS system storing a multimedia message transmitted from a specific transmitting mobile station and transmitting the multimedia message to a specific receiving mobile station in response to a download request from the receiving mobile station, comprising: an MMS relay server; a first Database (DB) storing the multimedia message whose transmission is requested; a second DB storing specification information of stations; a transcoder ascertaining a specification of the receiving mobile station with reference to the second DB in response to a request from the MMS relay server, and reconstructing the multimedia message whose transmission is requested to be appropriate for the ascertained specification of the receiving mobile station; and a content storage server storing media data of identical contents each having various formats, resolutions, or chords; wherein, when the transcoding of the image and/or audio data is not possible, the transcoder receives an alternative image and/or audio data having contents identical to that of the image and/or audio data included in the multimedia message whose transmission is requested, but having a format, a resolution or a chord appropriate for the specification of the receiving mobile station, converts the received multimedia message into a plurality of sub-messages, and transmits the converted multimedia message to the MMS relay server; wherein the MMS relay server transmits subsequent sub-messages to the receiving mobile station upon receiving subsequent requests from the receiving mobile station.
