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: 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.
