Abstract: A communication method is disclosed. The method includes: A session management function network element sends a first path establish request to a transport network control network element, where the first path establish request includes an identifier of an access network device, an identifier of a mobile gateway selected for a session, and a first transport network (TN) Quality of Service (QoS) parameter of a first QoS flow in the session, and the first TN QoS parameter of the first QoS flow is determined based on a TN QoS parameter mapped to a first service type of the first QoS flow, the access network device, and the mobile gateway. The session management function network element receives a first path establish response from the transport network control network element, where the first path establish response includes information about a first TN transmission path of the first QoS flow.
