PROCÉDÉ ET SYSTÈME DE COMMANDE DE SEUIL D'ENREGISTREMENT DE FACTURATION HORS LIGNE BASÉS SUR LE PROTOCOLE CUPS

摘要

Embodiments of this application provide an offline charging call detail record threshold control method and system based on a CUPS protocol. According to the method, after a CP establishes a session, a message that is sent to a UP carries a maximum quantity of charging condition changes. The UP reports charging information to the CP based on an instant query request sent by the CP or a subscription condition, and calculates a quantity of charging condition changes. If the quantity of charging condition changes that is obtained through calculation is less than the maximum quantity of charging condition changes, the UP continues to accumulate used traffic on the basis of existing accumulated used traffic. If the quantity of charging condition changes that is obtained through calculation is equal to the maximum quantity of charging condition changes, the UP clears charging information and a quantity of traffic containers for an offline charging call detail record on a UP side. The technical solutions provided in the embodiments of this application can reduce additional signaling interaction between the CP and the UP caused by a threshold update, thereby preventing a charging result of the offline charging call detail record from exceeding a threshold due to delayed update message exchange between the CP and the UP.
