Abstract

Le mode de réalisation de la présente invention fournit un procédé et un système pour traiter un service d'appel. Le procédé comprend les étapes consistant à : enregistrer le numéro du service d'appel qui est exécuté par le même abonné, quand le service d'appel a lieu une fois, augmenter le nombre enregistré du service d'appel actuel; quand le service d'appel est libéré une fois, réduire la valeur numérique du service d'appel en cours. En même temps, le procédé établit au préalable un seuil supérieur du nombre de service d'appel autorisé simultanément par un abonné. Quand l'abonné exécute un service d'appel, le procédé juge si le nombre actuellement enregistré du service d'appel est inférieur à la valeur de seuil supérieure établie au préalable pour autoriser le service d'appel, s'il ne l'est pas, alors le service d'appel n'est pas réalisé; s'il l'est, alors il autorise l'abonné à exécuter des services d'appel. Par conséquent, le procédé peut limiter les services d'appel réalisés simultanément par un abonné pendant une courte période et limiter de manière efficace la fraude réalisée par une personne malhonnête utilisant le service d'appel.
