Abstract

L'invention concerne un procédé et un dispositif de facturation. Le procédé comporte les étapes suivantes: une entité de PCRF détermine une première application qui doit être facturée, et attribue un identifiant de facturation à la première application; et l'entité de PCRF envoie respectivement un identifiant de la première application et l'identifiant de facturation attribué à la première application à un UE, une entité de PCEF et une entité de TDF, de telle façon que l'UE et l'entité de TDF ajoutent l'identifiant de facturation à un paquet de données de la première application, puis envoient celui-ci à l'entité de PCEF, et l'entité de PCEF facture indépendamment des paquets de données qui portent l'identifiant de facturation respectivement en provenance de l'UE et de l'entité de TDF sur la base de l'identifiant de la première application et de l'identifiant de facturation attribué à la première application. La solution technique de la présente invention peut réaliser une facturation par application.
