Method and system for transmitting multimedia message transmitted from transmitting mobile station of higher version to receiving mobile station of lower version
First Claim
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.

Abstract
The present invention relates to a method and system for transmitting a multimedia message, which reconstructs a multimedia message to be appropriate for the receiving mobile station and transmits the reconstructed message, when the multimedia message is requested to be transmitted from a transmitting station of a higher version to the receiving station of a lower version and the multimedia message may not be transcoded into a form which can be processed by the receiving mobile station. The present invention enables to transmit various types of multimedia message without being limited by the specification of the receiving mobile station.

4. An MMS method of 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:
-
a first step of ascertaining a specification of the receiving mobile station in response to a transcoding request; a second step of ascertaining whether image and/or audio data having contents identical with those of the image and/or audio data in the multimedia message and having a format, a resolution, or a chord appropriate for the specification of the receiving mobile station exists in a DB, when the transcoding of the requested multimedia message is impossible; a third step of reconstructing the multimedia message whose transmission is requested into image and/or audio data appropriate for the specification of the receiving mobile station if, as a result of the second step, the image and/or audio data exists; and
a fourth step of transmitting the multimedia message, reconstructed at the third step, to the receiving mobile station. - View Dependent Claims (5, 6, 7)
