Definitions

  • VRUs Voice response units
  • VRUs are used to provide the subscriber with account information such as the time available to talk and billing information. This information may be obtained in a variety of ways . Some prior art systems charge a constant price per unit of time and thereby simply requiring the account balance to be divided by the price to obtain the available talk time (i.e., number of time units which can be purchased) . These systems, while offering a straightforward approach for talk time calculations, are unable to support multiple rate time periods.

Since only one FIRST-SEGMENT exists for a given call with the remaining call time (ADDITIONAL-SEGMENTS) spread over one or more time periods, in considering subsequent time periods, the system uses only the ADDITIONAL-SEGMENTS calculations and associated rates (i.e., loop back to 111).

Abstract

L'invention concerne un procédé de calcul d'un temps maximum de conversation, caractérisé en ce qu'on détermine le tarif pour la période de temps à partir du moment où commence la conversation (08), on calcule le nombre maximum d'unités de temps restant dans la période de temps (20), on calcule le nombre maximum d'unités avant d'atteindre le temps de conversation maximum dans le système (136), on calcule les unités maximums avant que la provision disponible soit épuisée (138), on détermine les minimums des calculs précités au temps de conversation disponible et on soustrait la quantité d'une copie du solde de la carte à pré-paiement (118). Si les unités de temps maximums disponibles dans ladite période de temps sont égales au minimum des trois étapes de calcul, on répète les étapes précitées et on ajoute la quantité de temps de conversation (132).
