Message Driven User Operation

Message is sent by coding with embedded command, so a smart MDT will list received messages according to these embedded commands and shows them in different way, such as different color or font. Moreover, when a user manipulates a certain message, the corresponding operation is vary and depends on the embedded command. It may pop up a window for further operations, or just simply to change message color to indicate this message has been  read. It is very similar like the co-channel signaling in communication system.
