Abstract: Embodiments of the present invention relate to the communications field, and provide an MEC platform handover method, apparatus, and system. The method includes: receiving a handover notification sent by a handover notification device, where the handover notification device is a source access network device of to-be-handed-over UE or a target MEC platform of the to-be-handed-over UE; determining a TEID of the to-be-handed-over UE according to the handover notification; obtaining context of the to-be-handed-over UE according to the TEID of the to-be-handed-over UE; and sending the context to the target MEC platform. The present invention resolves a problem that provision of application data by an MEC platform to UE is interrupted when the UE is being handed over between access network devices, thereby providing continuous services to the UE. The present invention is applicable to a handover between MEC platforms.

Abstract: Example communication methods and apparatus are described. One example method includes determining a first encapsulation identifier corresponding to an Ethernet session by a control plane network element and sending the first encapsulation identifier corresponding to the Ethernet session to a user plane network element, where the first encapsulation identifier is used to instruct the user plane network element to process a data packet corresponding to the Ethernet session based on the first encapsulation identifier. The terminal device determines the first encapsulation identifier corresponding to the Ethernet session and encapsulates an uplink data packet based on the first encapsulation identifier, where the uplink data packet is a data packet triggered by an application program bound to the Ethernet session. The encapsulated data packet is mapped to the Ethernet session corresponding to the first encapsulation identifier for transmission based on the first encapsulation identifier.

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.

Abstract: This application provides a communication method and an apparatus. The method includes: An access management network element receives a registration request from a terminal device, and the access management network element obtains configuration type indication information, determines, based on the configuration type indication information, to perform restricted registration, and starts a restricted registration timer. After the restricted registration timer expires, the access management network element initiates a deregistration procedure to deregister the UE from a network. By using the method, the terminal device can be prevented from maliciously camping or accessing another service for a long time. In addition, this solution is simple to implement, and easy to deploy and implement.

Abstract: Embodiments of this application provide a local area network communication method, a device, and a system. The method includes: A session management network element obtains, in a session management process, an address or a virtual local area network identifier VID information of user equipment UE corresponding to each 5G local area network 5GLAN service accessed by a session, and obtains service area information of each 5GLAN service from a local area network controller LAN Controller. The SMF subscribes to, from a mobility management network element, a mobility event that is based on each 5GLAN service, and obtains a mobility event report that is based on a service area of the SMF, and a corresponding 5GLAN identifier. The SMF updates a rule of a corresponding session in a user plane network element based on the mobility event report.
