Claim:
A method for assigning a key and a display field of a first terminal allocated to the key, comprising: the first terminal of a first subscriber initiating a communication connection between the first terminal of the first subscriber and a second terminal of a second subscriber by communicating with a switching system to establish the communication connection; during the communication connection, the first terminal sending a first message having user input of the first subscriber to the switching system; the switching system recording an address identifying the second terminal with respect to the communication connection based upon the user input of the first subscriber; the switching system determining subscriber information associated with the recorded address; the switching system communicating at least one of the recorded address and the subscriber information to the first terminal; the first terminal assigning the recorded address to the key as a destination address for a future connection setup; the first terminal assigning the determined subscriber information to the display field such that at least a portion of the subscriber information is displayable via the display field when the key is actuated; and wherein the assigned recorded address and the assigned subscriber information are assigned by the first communication terminal during the communication connection such that at an end of the communication connection the assigned recorded address is still assigned to the key and assigned subscriber information is still assigned to the display field beyond an end of the communication connection such that a subsequent communication connection between the first terminal and the second terminal is initiatable by the first terminal upon actuation of the key.
