Abstract
A mobile-radio network (MRS) includes a mobile switching center (MSC) for receiving incoming calls from mobile-radio subscribers (A). In response to the incoming calls, certain ones of the incoming calls are selected if the respective mobile-radio subscriber (A) has a debit account assigned to it and the debit account has a credit balance. The credit balance is compared with a predetermined minimum balance (Dmin1) and a call is completed if the credit balance exceeds the predetermined minimum balance. The debit account for the respective mobile-radio subscriber is charged a unit fee. Incorporated in the mobile switching center (MSC) is a service switching point (SSP). Additionally, a service control point (SCP) is connected to the service switching point and includes an arithmetic unit (DC) for call charging. The mobile-radio network structure makes it possible to establish connections and charge incoming calls using simple exchange protocols (INAP) without having to change conventional network protocols (MAP).
