A computer system (2) for transmitting context-specific data via a mobile radio network to a mobile communication terminal (3, 3') and configured to receive and store condition data assigned to data elements of a data delivery unit (1). The computer system (2) checks whether the mobile communication terminal (3) satisfies one or more conditions defined by the condition data. If one of the conditions is satisfied, the computer system (2) triggers the transmission of context-specific data elements via the mobile radio network to the mobile communication terminal (3, 3'). The context-specific data elements are those data elements that are assigned to condition data that define the condition satisfied by the mobile communication terminal (3). Context monitoring by the computer system (2) and context-specific data transmission triggered by the computer system (2) make it possible to supply automatically context specific data elements, for example operational parameters, to mobile communication terminals (3, 3'), without having to burden, for that purpose, the data delivery units (1) and the mobile communication terminals (3, 3') with functions for context monitoring.
