Method for accessing fixed network and access gateway network element

Abstract

This application discloses a method for accessing a fixed network and an access gateway network element. The method carried out by an access gateway network element of a fixed network includes: performing a PPPoE negotiation with a terminal, to establish a PPPoE session with the terminal; negotiating a PPPoE authentication mode with the terminal; sending a PPPoE authentication parameter to an authentication service network element of a mobile network, where the PPPoE authentication parameter is used by the authentication service network element to perform PPPoE authentication on the terminal; and receiving a PPPoE authentication result from the authentication service network element, and sending a PPPoE authentication result message to the terminal, where the PPPoE authentication result message includes the PPPoE authentication result. Embodiments of this application are applied to authentication during an access from the mobile network to the fixed network.
