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.

Abstract translation: 一种通过消息传送服务器（22）从发送终端（21）发送多媒体消息的方法（以及对应的设备），例如MMS中的MMS代理中继或SIP IM中的SIP代理服务器到接收 终端（25）具有有限的多媒体能力，发送终端（21）适于包括用户代理（21a），用于向消息中插入足够详细信息的消息的媒体特性，以使消息服务器（22）能够确定 是否应该基于接收终端（25）的实际或假定的多媒体能力对消息进行代码转换，并且消息传送服务器（22）被配置为读取媒体特性并且基于插入的媒体特性来确定消息是否应该被转码 以及接收终端（25）的实际或假定的多媒体能力。 媒体特性有利地插入消息的标题中。
