The invention aims at providing a method, a subscriber terminal, a computer program product and a communication system, wherein a sender has the possibility of influencing the signaling signal in a terminal of a recipient and configuring individually and with greater freedom a signaling signal by choosing one or more data formats that can be sent in an MM standard, particularly when transmitting an MM. According to the invention, this is achieved in that an element causing immediate display of said element is identified as a signaling signal (S) when the data and/or a predetermined partial amount of data have arrived.
