Abstract: A method, an apparatus and a system for marking a service data packet are provided. A traffic detection function TDF is requested to detect a data flow description or data flow starting or ending information corresponding to a service application type. The detected data flow description or a data flow starting or ending information report, transmitted by the TDF, is received. A data packet marking rule is generated according to the data flow description or the data flow starting or ending information report. A session modification message carrying the data packet marking rule is transmitted to a bearer binding function entity BBF for the BBF to 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.

Abstract: A method, an apparatus and a system for key derivation are disclosed. The method includes the following steps: a target base station) receives multiple keys derived by a source base station, where the keys correspond to cells under control of the target base station; the target base station selects a key corresponding to the target cell after knowing a target cell that a user equipment (UE) wants to access. An apparatus for key derivation and a communications system are also provided.
