Service Context – Final Unit Indication Properties

The following Final Unit Indication (FUI) values can be defined for a service context type. They define information for the Diameter Final-Unit-Indication grouped AVP. You can configure FUI to be set dynamically during runtime based on valid pricing or you can specify values that get set to the same static value during runtime, without regard to any pricing.

Note: MATRIXX Engine supports both a FUI Generator ID that is chosen dynamically during rating to set Diameter FUI information and Final Unit Info properties that set constant values for the FUI information.
FUI Properties lists the FUI properties you can define for a service type.
Table 1. FUI Properties
Property Description Data Type
Final Unit Generator ID The ID of the FUI generator to use for dynamically selecting a FUI profile for the service context during rating.

A service context can be configured to use a Final Unit Generator ID or the following static Final Unit Information.

UINT 32
Final Unit Information
Last Unit Action Indicates the action to be taken when the subscriber's balance cannot cover the service cost. This value is used by the Final-Unit-Action AVP.
  • 0 – TERMINATE
  • 1 – REDIRECT
  • 2 – RESTRICT_ACCESS
When set to 1, you must set the Redirect Address Type and Redirect Address data values. When set to 2, you should also specify an optional sub-element, Final unit restriction filter or Final unit filter id. The default is 0 (TERMINATE). 		UINT 32
Redirect Address Type How the service access is redirected. This value is used for the Redirect-Address-Type AVP. If specified, the Redirect Address data attribute must also be specified. UINT 32
Redirect Address The IPv6 address, URL, or SIP URI to which the service access is redirected. This value depends on the Redirect Address Type and is used for Redirect-Server-Address AVP (UTF8String). String
Denial Validity Time A nonzero value represents a fixed time duration from the denial, regardless of upcoming time boundaries. During this time, service can be restored by modifying the subscription and triggering a request to restore service. After this time, the network is expected to send a request to restore service. Default is 0 (zero). Configurable for Redirect and Restrict Access actions.
When Denial Validity Time is 0:
  • Service is terminated.
  • Validity-Time is not included.
 UINT 32
Restriction Filter Rule A string value that is an IPFilterRule. This value is used for the Restriction-Filter-Rule AVP. For information about IPFilterRule, see RFC 6733 and RFC 4006. String
Filter ID A string value that is an IPFilterRule. This value is used for the for the Filter-Id AVP. String
