Abstract: This application provides a communication method and apparatus. The method includes: After receiving a first packet from a first device, a first user plane network element determines a user plane LAN identifier corresponding to the first packet, where the user plane LAN identifier is an identifier that is in a user plane and that is of a LAN group to which the terminal belongs, and one user plane LAN identifier corresponds to one LAN group. That is, a function of the user plane LAN identifier is to isolate user plane packets of different LAN groups. Then, the first user plane network element sends the first packet to a second device based on the user plane LAN identifier and a destination address included in the first packet, so that the first packet sent by one terminal in the LAN group is sent to another terminal in the LAN group.

Abstract: In a communication method, when a terminal device initiates establishment of a session of an Ethernet type, a virtual local area network management function entity in a communications system may determine a virtual local area network identifier of a user group to which the terminal device belongs. In this way, a user plane function entity in the session of the terminal device may allocate a plurality of virtual ports to a virtual local area network whose identifier is the virtual local area network identifier and may broadcast the Ethernet broadcast frame on the plurality of virtual ports.

Abstract: This application provides a user group establishment method and an apparatus. The method includes: After receiving a first message from a communications device, a user group management function network element generates an identifier of a user group based on the first message, and sends the generated identifier of the user group to a terminal by using a communications network element, so that the user group of the terminal is established in a 3GPP network, and the generated identifier of the user group is sent to the communications device.

Abstract: This application provides a data transmission method, a communications apparatus, and a session management function entity. The method includes obtaining, by a communications apparatus, a correspondence between a quality of service flow identifier of a service flow and an inter-packet time interval of the service flow. The method also includes establishing, by the communications apparatus based on the correspondence, a gate queue used to send a data packet. The method further includes establishing a mapping relationship between the gate queue and the quality of service flow identifier. The method also includes receiving, by the communications apparatus, a data packet from an upper-level sending device of a transmission link. The method further includes if the data packet includes the quality of service flow identifier, periodically scheduling, by the communications apparatus, the data packet based on the gate queue to which the quality of service flow identifier is mapped.

Abstract: A network management method and a controller are provided. Elastic scaling of an in-network packet data network IN-PDN is implemented when UE is migrated or detached. In addition, service continuity in a local network of the UE can still be ensured when the UE is migrated or detached, and an IN-PDN resource that is no longer used is reclaimed in time, thereby avoiding a waste of the IN-PDN resource.

Abstract: A mobility management method and apparatus are provided, to flexibly switch a forwarding path, and ensure service continuity in a movement process of a terminal device. The method includes: A control plane network element determines a changed media access control address MAC address of a first terminal device after the first terminal device moves. Then, the control plane network element determines at least one second terminal device that belongs to a same terminal device group as the first terminal device, where the first terminal device is a terminal device whose address changes after the movement, and the at least one second terminal device is a terminal device other than the first terminal device in the terminal device group. Finally, the control plane network element notifies the first terminal device and the at least one second terminal device to update to the changed MAC address of the first terminal device.
