SBR elements

This table describes the fields on the CPA > Configuration > SBR page.

Field (* indicates required field) Description Data Input Notes

* SBDB audit Start Time

Time of day in UTC to start the audit process.

The audit process removes stale bindings from the Charging SBR. Since the audit window is configurable, the audit process calculates the rate at which to delete records based on the number of expected stale bindings and the configured duration of the daily audit. The longer the audit window is, the slower the deletion rate.

If your system has a daily period of lower customer activity, you may wish to schedule the audit for that time. Otherwise, you can reduce the performance load of the process by allowing it more time during the day to complete its audit.

Format: pull-down list

Range: 12:00 AM - 11:00 PM, UTC

Default: 2:00 AM

* SBDB audit Stop Time

Time of day in UTC to stop the audit process. Must be at least 1 hour past the start time.

Format: pull-down list

Range: 12:00 AM - 11:00 PM, UTC

Default: 3:00 AM

* Stale SBDB session binding age

Age after which a session will be considered stale and eligible for removal during audit.

Note that increasing the age will increase memory usage.

Age is specified in days.

Format: numeric

Range: 1-30

Default: 2

* Maximum active session bindings

Session binding count used to calculate the session binding count alarms.

Once this setting is reached, the Charging SBR will issue an alarm; however, it will continue to store bindings.

Format: numeric

Range: 1 - 100,000,000

Default: 35,000,000

* SBDB Mostly Stale Percentage

Percent of stale session age when a session binding is considered mostly stale.

This setting is not used by the audit process. However, it is used to generate measurements.

Format: numeric

Range: 1-99

Default: 90
