Abstract: PURPOSE: A method for restoring a session at a diameter server is provided to restore the existing activated session used by a subscriber in the case of losing session information of the subscriber due to a failure of a system and manage a dynamic address of the subscriber even after restoring the session of the subscriber. CONSTITUTION: A diameter server transmits activated session information to adjacent diameter nodes at a point when a session of a subscriber is activated(501). The diameter server inquires session information to the adjacent diameter node and receives responses from the adjacent diameter node(503-505). The diameter server stores the received session information by nodes(507). The diameter server classifies the stored session information by nodes according to session identifiers(509-513). The diameter server extracts and stores the session information to be restored, by using subscriber information(515-527).
