HSS Watchdog Keepalives

The home subscriber server configuration element contains a watchdog-ka-timer parameter that sets a time to send DWR messages to the HSS. This is similar to external policy server Diameter Heartbeat functionality. When 3/4 of this timer elapses, the Oracle Communications Session Border Controlleri begins disconnection processes. DWR message creation is suspended when any other activity with the HSS occurs within watchdog-ka-timer seconds. DWR creation resumes watchdog-ka-timer seconds if all other traffic stops.
