One or more preferred call numbers are defined and managed for mobile subscribers. A destination number dialed with the call is compared to the preferred call numbers for the mobile subscriber. When the destination call number is identical to a preferred call number, the call charges are determined by a charging device in the mobile network in a different manner than the usual charge. The storing of the preferred call numbers can occur at the mobile station side in a mobile station or at the network side. Based on the subscriber-specific stipulation of preferred call numbers, mobile subscribers have the ability to select and define specific call destinations which are charged differently than other calls, for instance according to a more favorable fee schedule. This increases the flexibility of the mobile subscribers and network operators with respect to the scheduling of calling rates.
