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: Example end marker sending methods are described. In one example method, a user plane gateway (UP GW) determines when to send an end marker based on trigger information, so as to sort one or more downlink data packets received on a target user plane path based on the end marker. The UP GW receives trigger information and an identifier (ID) of a source user plane path of user equipment (UE) that are sent by a control plane (CP) node, where the UP GW is located on the source user plane path. The UP GW sends an end marker to an access network (AN) node on the source user plane path based on the trigger information and the ID of the source user plane path.

Abstract: Embodiments of the present application provide a communication method and a device, which are used for inter-system handover of UE, so that a connection can be established between a source application management unit and a target application management unit, thereby effectively improving communication efficiency. The method in the embodiments of the present application includes: obtaining, by a network device, a source system identifier of a source application system and/or a target system identifier of a target application system; and sending, by the network device, the source system identifier to a target application management unit, or sending the target system identifier to a source application management unit, so that a connection is established between the source application management unit and the target application management unit, and the source application management unit and the target application management unit communicate with each other.
