Abstract: Embodiments of this application provide a device and a system of a virtual network service across session management network elements. A group session management network element obtains tunnel information of a first user plane network element serving a first terminal device belonging to a first virtual network group, sends a first message to a second session management network element, where the first message includes an identifier of the first terminal device, an identifier of the first virtual network group, and the tunnel information of the first user plane network element for configuring a first forwarding rule on a second user plane network element, and the first forwarding rule is used by the second user plane network element to send a first data packet to the first user plane network element when one terminal device belonging to the first virtual network group sends the first data packet to the first terminal device.

Abstract: Embodiments of this application disclose a communication method including: An SMF network element receives a first application request for requesting to provide a service of a 5GVN for a first LAN in a data network, and the first application request carries address segment information of the first LAN, information that is about a target group and that corresponds to the first LAN, and interface information of a first tunnel interface of a first LSW in the first LAN. The SMF network element determines a first UPF network element that provides the service of the 5GVN and sends first routing information to the first UPF network element, where the first routing information indicates the first UPF network element to forward received first data to the first tunnel interface, and a destination address of the first data is any address included in the address segment information of the first LAN.
