  • EP 1 038 387 B1 describes a method for billing a call from a subscriber identified with an identification card known a telecommunications network.
  • the duration of the call is measured by a time measuring device integrated in the identification card.
  • a time controller checks the time determined in the identification card and transmits a time receipt to the identification card if the time is incorrect.

The amount determined can then either be debited directly to a prepaid account on the identification card and / or packed in an invoice document and transmitted to a debit server in the telecommunications network.
  • the subscribers of the mobile radio network receive a charge calculation at predetermined time intervals, for example at monthly intervals.
  • the charge calculated for this is displayed by the handset after a telephone call.

This uncertainty arises, among other things, from the fact that no general assignment between see numbers and the associated network operators is possible, since the original network-specific phone numbers can be retained when changing to another network operator.
  • the invention is based on the object of enabling the subscribers of a mobile radio network to be able to exercise the best possible cost control at all times. This object is achieved by a method with the combination of features of claim 1.
  • the method according to the invention relates to the operation of a mobile part in a mobile radio network, the mobile part having a security module with the aid of which access to the mobile radio network can be obtained.

  • the invention has the advantage that a high degree of cost transparency is achieved when using chargeable services with a mobile part in a mobile radio network.
  • the display of the charge rate is controlled by the security module. This makes it possible to retrofit the display function on a conventional handset using the security module.
  • the rate of charge can be disregarded, so that the user of the handset can decide under which conditions he would like to be informed about the rate of charge.
