The present invention relates to the field of network communications, and in particular, to a method, an apparatus and a system for updating an Authentication, Authorization and Accounting AAA session. The method includes: receiving an AAA session request sent by a second network access server, where the AAA session request includes a second session identifier and an ERP message; and updating a session according to the second session identifier and a stored first session identifier after successful user authentication that is performed according to the ERP message, where the first session identifier and the second session identifier correspond to the same user. By adopting technical solutions provided in embodiments of the present invention, as the session is updated according to the second session identifier and the stored first session identifier, synchronization of session information is ensured, thereby resolving an abnormal session problem that occurs when a home AAA server initiates a session or the network access server uses a session after re-authentication.
