Abstract: A data routing method and apparatus resolve a problem that data packet forwarding efficiency is greatly reduced because a service function instance sequence needs to be retrieved for each data packet according to a 5-tuple of a data flow to which the data packet belongs. The data routing method includes: receiving, by a traffic classifier, a data packet, where the data packet belongs to a first data flow; allocating, by the traffic classifier, a first data route identifier to the first data flow, where the first data route identifier is used to identify a service function chain of the first data flow and is used to identify the first data flow; adding, by the traffic classifier, the first data route identifier to the data packet; and sending, by the traffic classifier, the data packet to a service function forwarding device.

Abstract: A data packet processing method and apparatus, where a storage apparatus disposed on a network side stores a correspondence between an identifier and data flow characteristic information. When configuring a policy for a data packet including a first identifier, a network-side device requests the storage apparatus for data flow characteristic information corresponding to the first identifier. A policy and charging enforcement function (PCEF) receives a data packet that is sent by a user equipment (UE), matches the data packet against the data flow characteristic information, and when the data packet matches the data flow characteristic information, executes a policy on the data packet according to policy information corresponding to the first identifier.

Abstract: The embodiments of the application disclose a mobile handover method. The method includes: a first network device receives first information, and learns that a first terminal device is handed over to a target access network device. The first network device sends second information to a second network device, and the second network device determines, based on the second information, whether to reselect a target user plane function device for the first terminal device; and/or the first network device sends third information to a third network device, and the third network device determines, based on the third information, whether to reselect a target application server for the first terminal device. If the target user plane function device and/or the target application server need/needs to be reselected, a user plane function device and/or an application server need/needs to be handed over in a timely manner.
