Embodiments of the present invention provide a method, an apparatus and a system for marking a service data packet, which relate to the field of communications, and improve the user experience. The method includes: requesting a traffic detection function TDF to detect a data flow description corresponding to a service application type or data flow starting or ending information corresponding to the service application type; receiving, transmitted by the TDF, the detected data flow description or a data flow starting or ending information report, and generating a data packet marking rule according to the data flow description or the data flow starting or ending information report; and transmitting, to a bearer binding function entity BBF, a session modification message carrying the data packet marking rule, so that the BBF can map a data flow identified by the session modification message to a bearer according to the session modification message, and mark a GTP-U header according to the data packet marking rule. Embodiments of the present invention are used for marking the GTP-U header for the data flow of an application service. |
