MEDIA ADAPTATION DETERMINATION FOR WIRELESS TERMINALS
First Claim
1. A messaging server, comprising a processor configured to:
- obtain media characteristics of a multimedia message inserted into the multimedia message intended for a receiving terminal;
decide whether the multimedia message should be transcoded based only on comparing the media characteristics of the multimedia message with at least one of actual multimedia capabilities and assumed multimedia capabilities of the receiving terminal; and
remove the media characteristics that are inserted into the multimedia message before sending the multimedia message to the receiving terminal when transcoding is not needed.

Abstract
A method (and corresponding equipment) by which a multimedia message is sent from a sending terminal (21) via a messaging server (22)—such as a MMS Proxy-Relay in MMS or a SIP proxy server in SIP IM—to a receiving terminal (25) having limited multimedia capabilities, with the sending terminal (21) adapted to include a user agent (21a) for inserting, into the message, media characteristics of the message sufficient in detail to enable the messaging server (22) to determine whether the message should be transcoded based on actual or assumed multimedia capabilities of the receiving terminal (25), and with the messaging server (22) configured to read the media characteristics and decide whether the message should be transcoded based only on the inserted media characteristics and on actual or assumed multimedia capabilities of the receiving terminal (25). The media characteristics are advantageously inserted into the header of the message.
