Abstract: Embodiments of this application provide a user plane rerouting method and apparatus. The method includes: a first network element receives user plane rerouting trigger information sent by a second network element, where the user plane rerouting trigger information is sent when the second network element detects a preset service packet that matches a packet detection rule PDR, and the PDR is used to indicate matching information and an execution rule that are corresponding to the preset service packet triggering user plane rerouting. The first network element further performs the user plane rerouting based on the user plane rerouting trigger information.

Abstract: The present disclosure relates to implementing policy control. In one example communication system, a core network exposes a service policy to an application server, and the application server authorizes user equipment with the service policy. Before accessing a service provided by the application server, the user equipment pushes, to the core network, the service policy that needs to be used to access the application server. A core network device performs policy control such as charging, QoS, routing, gating control, or redirection on a service flow or a data packet between the user equipment and the application server according to the service policy pushed by the user equipment.

Abstract: A method for replaying a log on a data node, a data node, and a database system are described. The method is used to improve a log replay speed, and includes: the data node obtaining a plurality of logs, wherein the plurality of logs includes at least one transaction commit log and at least one page operation log; and a first thread of a plurality of threads replaying the at least one page operation log, and a same second thread replaying all page operation logs including an operation on a same page. As such, log replay progress does not need to be synchronized between threads. A process in which the first thread replays the transaction commit log is independent of a process in which at least one second thread replays the at least one page operation log.

Abstract: An application server switching method, applied to a scenario in which a handover occurs between user plane network elements corresponding to a terminal device, includes obtaining, based on a user plane network element of the user plane network elements after the handover and a correspondence between the user plane network element and an address of a local application server of one or more application servers deployed on a network, the address of the local application server corresponding to the user plane network element after the handover. The correspondence between the user plane network element and the address of the local application server is used to indicate the address of the local application server. The method also includes sending the address of the local application server corresponding to the user plane network element after the handover.
