    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: A data transmission method, a device, and a data transmission system implement local interaction between two terminals when the two terminals are served by different UPF entities. The method performed by a first user plane function entity includes receiving a data packet from a first terminal through an uplink path corresponding to the first terminal, where the data packet carries addressing information of a second terminal; determining path information of a second user plane function entity based on information about the uplink path corresponding to the first terminal and the addressing information of the second terminal; sending the data packet to the second user plane function entity based on the path information of the second user plane function entity; and sending the data packet to the second terminal through a downlink path corresponding to the second terminal.
