SESSION UPDATING PROCEDURE FOR AUTHENTICATION, AUTHORIZATION AND ACCOUNTING

摘要

For authentication, authorization and accounting of a user, an AAA server in whose domain the user initialized a session for authentication and authorization of the user with the user's home domain is set as an anchor AAA server. During a handover of the user between different access nodes during the session, session update message to and from the anchor AAA server is used to update the session path. The downstream pointer from the home domain's AAA server to the anchor AAA server is kept unchanged.
