3.1.6.2 Session Cleanup Timer Event

When the Session Cleanup Timer (section 3.1.2.2) expires, the protocol SHOULD apply the following logic to close an idle session:

  • If the SessionActive ADM element is FALSE, the protocol SHOULD close the session as specified in Closing a Session (section 3.1.5.9).

  • If the SessionActive ADM element is TRUE, the protocol SHOULD restart the Session Cleanup Timer and set the SessionActive ADM element to FALSE.
