In the method and system for monitoring the fees arising for calls in a mobile radiotelephone system, billing data is offered and a charge limit (CL) is defined for every individual call, a limited calling time (TA) for the respective call being calculated on the basis thereof. In parallel to the limitation of the call to a specific time duration, a monitoring function is started at every call with which the call is automatically cleared down upon expiration of the limited calling time (TA). By the limitation of the calling time per call and by the monitoring function, the charges incurred during the respective call cannot exceed an upper limit and a misuse of the mobile radiotelephone system, particularly given forwarded or transferred calls, is avoided in a simple manner.
