Abstract: A packet forwarding method includes that a session management network element sends a path identifier to a first device, where the first device includes an access network element corresponding to a protocol data unit (PDU) session and a user plane network element corresponding to the PDU session, the PDU session corresponds to a first terminal, the path identifier indicates a first path from the access network element to the user plane network element, the first path includes a part or all of a second path, and the second path is a path corresponding to a PDU session pre-established by the session management network element for a second terminal. The session management network element further sends, to the first device, identification information of a destination address corresponding to the path identifier.
