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: A network handover method is disclosed, where after UE in an LTE network requests circuit switched fallback CSFB, an MME instructs an eNB to move the UE from the LTE network to a 2G or 3G network, and requests an MSC to hand over the UE from the LTE network to a CS domain of the 2G or 3G network for the CSFB, so that the 2G or 3G network allocates a CS domain resource to the UE. After handing over to the CS domain, the UE may perform a CS domain call. By using embodiments of the present invention, an access delay is reduced when the UE accesses the CS domain of the 2G or 3G network, duration of an entire voice call is shortened, and user experience is improved.

Abstract: The present invention discloses a network handover method. After receiving a request message that requests circuit switched fallback (CSFB) and that is initiated by a UE located in an LTE network, an MME requests an MSC to hand over the UE from the LTE network to a CS domain of the 2G or 3G network; and after receiving a radio access bearer (RAB) sent by the MSC, the MME sends the RAB to the eNB, so that the RAB is sent by an eNB to the UE, where the RAB is a RAB whose domain identifier is a packet switched (PS) domain, or the RAB is a PS RAB. Therefore, the UE can be handed over to a PS domain of the 2G or 3G network in a manner of being handed over from the LTE network to the CS domain of the 2G or 3G network.
