| 摘要 |
The present invention discloses a charging method, a TDF entity, a PCEF entity, a charging system, a PCRF entity, and a system. The method includes: acquiring, by a TDF entity, a correlation identifier of a data flow of an application borne by the TDF entity; and sending, by the TDF entity, first charging information to a charging system, where the first charging information carries the correlation identifier of the data flow of the application borne by the TDF entity, so that the charging system performs, according to the correlation identifier of the data flow of the application borne by the TDF entity and a correlation identifier of a data flow borne by a PCEF entity, correlation processing for the first charging information and second charging information that is sent by the PCEF entity to the charging system, where the second charging information carries the correlation identifier of the data flow borne by the PCEF entity. In embodiments of the present invention, a correlation identifier is carried in charging information, so that correlation processing may be performed for charging information of a data flow and charging information of an application. Thereby, accurate charging can be performed for the data flow and the application. |
