A communication terminal for use in a communication system comprises a display unit having a display screen onto which call states of different terminals in the system are represented by means of icons of different sizes and shapes, depending on the current call state of the terminal itself and the call states of other terminals in the system, in a quasi three-dimensional communication scene so as to graphically represent and distinguish terminal users involved in a communication scenario, displaying of the icons being such that a terminal user of the terminal perceives a substantial change of the communication scene upon call state changes of the terminal and other terminals in the system.
