Abstract: Embodiments of this application disclose a request processing method and a corresponding entity, to control a data notification and signaling that is used for triggering paging, thereby avoiding overload of a network element in a core network. The request processing method includes: determining, by an AMF, a first control plane function entity for a terminal device; determining, by the AMF, that the terminal device enters an idle state; obtaining, by the AMF, a first reachability service invocation request from the first control plane function entity; and rejecting, by the AMF, the first reachability service invocation request when the AMF determines, based on the first reachability service invocation request, that a reachability service invocation limitation condition is satisfied.

Abstract: A data migration method and an apparatus are applied to a scenario in which a user plane gateway communicating with a terminal is changed from a source user plane gateway to a target user plane gateway. The target user plane gateway receives an address of the terminal from a control plane gateway, obtains an Ethernet data packet based on the address of the terminal, and sends the Ethernet data packet to an Ethernet interface, so that a switch obtains the Ethernet data packet through the Ethernet interface, and updates a MAC address table based on the Ethernet data packet.
