Abstract

To achieve an improved overview on service charges for a subscriber to a digital cellular communication network it is proposed to provide a mobile station with a charging indicating unit ( ) adapted to receive charging information as unstructured supplementary service data messages (USSD) via the unstructured supplementary service data dialog. Therefore, it is possible to provide charging information without any impact on the hardware of the mobile station (MS). Further, as more detailed information on the kind of service and on the amount of data transferred is available a detailed estimate on the actual cost may be displayed to the user of the mobile station.
