L'invention concerne un procédé et un dispositif de déduction de facture de flux de service d'utilisateur, et le procédé comprend les étapes suivantes : la détermination du flux statistique de service de liaison descendante signalé selon le flux de service de liaison descendante et le flux de perte de paquets ; la transmission du flux statistique de service de liaison descendante par un message d'indication de signalement d'événement à une fonction d'application de politique et de facturation pour calculer une déduction de facture de flux de service d'utilisateur. En visant le problème dans l'art selon lequel le flux de perte de paquets du flux de service de liaison descendante en fonction de la liaison d'interface d'IP mobile de mandataire (PMIP)/IP mobile (MIP) et le flux de perte de paquets actifs du flux de service de liaison descendante dans le dispositif de fonction de signalement d'événement et de lien de porteuse (BBERF) ne peuvent pas être déduits pendant la facturation du flux de service d'utilisateur, le procédé de déduction de facture de flux de service d'utilisateur pour ledit flux de perte de paquets de service de liaison descendante est obtenu, et la précision de la facturation de flux de service dans la fonction d'application de politique et de facturation (PCEF) (intégrée dans le portail de réseaux de données groupés PDN-GW) est améliorée.
