Abstract: Embodiments of the present invention provide a method, device, and system for scheduling a data flow, which are used to improve the processing efficiency. A network side device marks a priority of a subsequent uplink and/or downlink data flow of a UE corresponding to a downlink data packet in the downlink data packet, and enables a downstream node to schedule an access network resource or air interface resource according to the priority. Therefore, a bearer does not need to be modified during the process of distinguishing different service flows and performing differentiation scheduling on different service flows, thereby reducing the workload and improving the processing efficiency.

Abstract: Embodiments of the present invention provide a method for triggering data offload. The method includes: receiving, by a first network element from a home subscriber server HSS, information of a packet data network PDN connection, where the information includes offload indication information, and the PDN connection is established by a UE through a second access network; and obtaining, by the first network element, the offload indication information, and triggering, according to the offload indication information, processing of offloading a data flow in the PDN connection to a first access network. In the foregoing provided solution, the UE does not need to indicate, to the first network element, information that offloading is required for the PDN connection, and therefore the UE does not need to support an IKEv2 protocol. This lowers a requirement of the foregoing offload technology on the UE.
