ABSTRACT:
In one aspect, a method for realizing a presence service with a buddy list that can be displayed on a display device of a terminal is provided. In an activated state, the buddy list itself is displayed, and in a deactivated state, the buddy list itself is not visible. The buddy list is updated by a control device during a change in state of at lest one subscriber to be monitored and/or of at least one device assigned to the subscriber. According to the invention, the updating of the buddy list ensues in the deactivated state by means of the control device while using a method other than one used in the activated state.
