Patent

CA 2292476

A method (100) is disclosed such that when a call is being set up (104) from or to a mobile (or fixed) pre-paid subscriber, a portion of the value in the subscriber's pre-paid account is withdrawn (114, 120) to cover the cost of the call. Preferably, the amount withdrawn (114, 120) is large enough to cover the cost for a call of typical duration (e.g., 4 minutes). At call set up (104), for example, in an Intelligent Network (10), this amount is withdrawn (114, 120) from the account and allocated to the call being set up. If this amount is not completely used up, the remainder is returned (146) to the pre-paid account. If, however, the allocated amount is depleted (124) before the call is completed, a second allocation or withdrawal from the account is requested for that call. If the value left in the account is large enough to cover the second withdrawal request, a second amount is withdrawn (114, 120) and allocated to cover the ongoing call. If needed, additional withdrawals (114, 120) can be made to cover the ongoing call until it is completed. Once the call is completed (142), any remainder of the allocated amount is returned (146) to the pre-paid account. Consequently, a pre-paid subscriber can have a plurality of parallel ongoing calls, and because the amount in the pre-paid account is being monitored (116, 122) and accounted for before or while the calls occur, there is no risk that these calls will not be covered by the amount in the pre-paid account.

L'invention concerne un procédé (100) selon lequel, lorsqu'une communication est établie (104) par un abonné mobile (ou fixe) à prépaiement ou vers celui-ci, une partie de la valeur du compte prépayé de l'abonné est déduite (114, 120) pour couvrir le coût de la communication. Le montant déduit (114, 120) est, de préférence, suffisant pour couvrir le coût d'une communication de durée normale (p.ex. 4 minutes). Lors de l'établissement d'une communication (104), par exemple, dans un réseau intelligent (10), ce montant est déduit (114, 120) du compte et imputé à la communication en cours d'établissement. Si ce montant n'est pas entièrement utilisé, le solde est renvoyé (146) sur le compte prépayé. En revanche, si le montant alloué est épuisé (124) avant la fin de la communication, un(e) second(e) imputation ou déduction du compte est demandé(e) pour cette communication. Si la valeur laissée sur le compte est suffisante pour couvrir la seconde demande de retrait, un second montant est retiré (114, 120) et imputé à la communication en cours. Si besoin, des retraits (114, 120) supplémentaires peuvent être effectués pour couvrir la communication en cours jusqu'à son terme. Une fois la communication terminée (142), tout solde du montant affecté est renvoyé (146) au compte prépayé. En conséquence, un abonné à prépaiement peut avoir plusieurs communications en cours parallèlement. De plus, le montant du compte prépayé étant surveillé (116, 122) et pris en compte avant et pendant la communication, ces communications ne risquent pas de ne pas être couvertes par le montant du compte prépayé.
