  • Patent number: 10873886
    Abstract: The present disclosure relates to a mobile edge platform switching method. In one example method, an application identity of a source application instance is received by a second mobile edge platform from a first mobile edge platform. The first mobile edge platform provides a service for the source application instance. The source application instance provides a service for a user equipment. A target application instance of the user equipment is determined based on the application identity. The application identity of the source application instance is the same as an application identity of the target application instance. The second mobile edge platform provides a service for the target application instance. A switching notification message is sent by the second mobile edge platform to the target application instance. The switching notification message is used to instruct the target application instance to provide a service for the user equipment.

  • Publication number: 20200015138
    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.
