If a value other than the default Stale Session Timeout value is desired, enter the desired length of time in hours in the Stale Session Timeout (Hrs) Value field.For sessions that are not associated with any configured Access Point Names, the default Stale Session Timeout value in the table is used. The default is 168 hours (7 days), and the range is 1-2400 hours (1 hour to 100 days).
The Last Updated field is a read-only field that displays the date and time that this APN was created, or the last time the PCRF Pool Name was changed, whichever is most recent. This field records the time and date of changes that might affect routing of binding-capable session initiation requests. You can compare this date and time to the binding creation times when troubleshooting using the Binding Key Query Tool.
