Abstract: A data packet processing method and apparatus is disclosed. According to the method, 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 PCEF receives a data packet that is sent by 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. According to the method provided in embodiments of the present disclosure, transmitting a considerable amount of data flow characteristic information on an interface of an SCEF is avoided, and load on the SCEF is relieved.

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: This application provides a network handover method and an apparatus. Before a terminal device is handed over from a first network to a second network, the terminal device sets up a first tunnel to a first interworking device, where a communication identifier, of the terminal device, in the first tunnel is a first identifier the first identifier is an identifier used in the first network by the terminal device, and the first interworking device is an interface device in the first network and oriented toward a network other than the first network. After the terminal device is handed over from the first network to the second network, the terminal device sends an update request to the first interworking device, where the update request to update the communication identifier to a second identifier, and the second identifier is an identifier used in the second network by the terminal device.
