1. A communication method, comprising:
receiving, by a broadband network gateway (BNG), a dial-up packet sent by a fixed network device;
generating, by the BNG, first authentication information of the fixed network device based on the dial-up packet, wherein the first authentication information comprises an identifier of the fixed network device; and
sending, by the BNG, an access request message to a fixed mobile interworking function (FMIF), wherein the access request message carries the first authentication information, wherein the access request message is used by the FMIF to request a core network device to perform authentication on the fixed network device including a fixed network residential gateway based on the first authentication information, and wherein a communications network to which the core network device belongs is a 5G communications network or a communications network later than a 5G communications network.
