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.

Abstract: A method for sending an end marker, a device, and a system, where the method includes receiving, by a source access node (AN) through a source path between the source AN and a core-network user-plane device, a first end marker sent by the core-network user-plane device. The method further includes generating, by the source AN, N second end marker(s) based on the first end marker, where N is a number of source data radio bearers (DRBs) corresponding to the source path, and sending, by the source AN, the N second end marker(s) to a target AN through a forwarding path corresponding to the source path.

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 routing rule obtaining method, device, and system are provided. The method is applied to an MEC system and performed by a data bus controller, including: obtaining service information of at least one service in the MEC system, where service information of each service includes a service type and a service identity; generating a routing rule according to the service information of the at least one service, where the routing rule is used to indicate at least one path through which a data packet can pass; and sending the routing rule to a data bus, so that the data bus forwards, according to the routing rule, a received data packet to a service corresponding to the data packet. The service information of each service is dynamically obtained, so as to update a path indicated in a routing rule.

Abstract: A routing rule management method and a communications apparatus, where after a first user plane function network element receives, through a protocol data unit (PDU) session, a first data packet, from a terminal, whose source address is a first address, the first user plane function network element generates a first routing rule corresponding to the PDU session when determining that the first address is an unknown media access control (MAC) address, and where the first routing rule is used to forward, to the PDU session, a data packet sent to the first address. After detecting the unknown MAC address, the first user plane function network element may generate a routing rule corresponding to the unknown MAC address without involvement of a session management function network element.
