Closed User Group Normalizer

The closed user group normalizer, depending on configuration, either compares whether the subscription initiating an event is in the same group as the subscription receiving the event, or whether the subscription initiating an event is on the same same sub-domain as the subscription receiving the event.

For group comparisons, if the subscriptions are at the same hierarchical level (group tier) in the same group, rating uses the associated normalization value. The closed user group normalizer can work on any group tier, not just the immediate parent group. The normalizer specifies the group tier. Each group has a tier parameter that specifies a level in a group hierarchy, for example:
  • Department
  • Division
  • MVNO
The normalizer compares whether the caller and callee are in the same group at the specified tier.

For network comparisons, if the subscriptions (for example, the caller and the callee) are in the same sub-domain, rating uses the associated normalization value.

This normalizer has two possible parameter values that you cannot change: a value representing No and a value representing Yes. To ensure that rating behaves as expected, you must set the No value first, and it must be the first item in the list of values.

If both subscriptions are in the same group and at the same hierarchical level specified by the Tier value in the normalizer, or if both subscriptions are on the same sub-domain, specified by setting the Tier value to global in the normalizer, rating uses the index associated with the Yes parameter value. Otherwise, rating uses the index associated with the No parameter value.
Note: When normalizing on the called station, in most situations, the called station is a MSISDN. When the value is a MSISDN, the referenced device container should be MtxMobileDeviceAccessObject and the field should be AccessNumber.

You define tier names for groups by adding the tier names to the Field Definitions list in the My MATRIXX Application Configuration interface. If the names are not defined, they will not be available in the normalizer definition's Tier list. For information about adding field definitions, see the discussion about field definitions in My MATRIXX Help.
