Abstract
This application discloses a communication method, and relates to the communications field. In the method, a fixed mobile interworking function (FMIF) receives an access request message that carries first authentication information of a fixed network device and that is sent by a broadband network gateway (BNG), where the first authentication information is generated by the BNG based on a dial-up packet sent by the fixed network device, and the first authentication information includes an identifier of the fixed network device. The FMIF encapsulates the first authentication message in a message format supported by a control plane interface between the FMIF and a core network device, to obtain a second authentication message; and the FMIF sends the second authentication message to the core network device through the control plane interface. The core network device performs authentication on the fixed network device based on the second authentication message.
