Diameter Configuration for FABR

The following Diameter configuration must be done before FABR configuration can be performed.

All Diameter Configuration is done using the SOAM GUI in a DSR topology.

Use the Diameter User's Guide to complete the Diameter configuration, including the Diameter components needed for use with FABR.

1. Application IDs

   Diameter Application IDs must be configured prior to making them available for use in a FABR Address Resolution. Use the Diameter > Configuration > Application Ids [Insert] page to configure Diameter Application IDs.

   The Application IDs that need to be configured depend on the types of Diameter servers being supported, including HSS, PCRF, OFCS, OCS, and AAA.

2. Command Codes

   Diameter Command Codes must be configured prior to using them in a FABR Address Resolution. Use the Diameter > Configuration > Command Codes [Insert] page to configure Diameter Command Codes.

   Configure any Command Codes that need to be handled by FABR. The Command Codes are associated with the Diameter applications supported by the Diameter servers (for example, HSS, PCRF, OCFS, OCS, or AAA), which are the destination of Diameter Requests being routed by FABR. For example, the combination of Application ID = S6a and Command Code = ULR/ULA might be relevant for HSS.

3. Application Route Tables

   Either use the default Application Route Table (always available), or use the Diameter > Configuration > Command Codes > Application Route Tables [Insert] page to configure one or more Application Route Tables in addition to the default. Application Route Tables contain Application Routing Rules that direct messages to FABR and other DSR applications.

4. Application Routing Rules

   On the Diameter > Configuration > Command Codes > Application Route Tables page, select an Application Route Table Name and click View/Edit Rules.

   Use the Viewing Rules for Application Route Table page to insert or edit an Application Routing Rule with the Application Name set to FABR so messages are directed to FABR.

   If the FABR application and the DM-IWF application are chained so both of them can process the same Request message, insert or edit a second Application Routing Rule with the Application Name set to DM-IWF.

   Set the Priority in each of the two Application Routing Rules to indicate which application processes the message first (the higher priority processes first).

   • Set the Application Name to FABR.
   • In the Conditions field, set the Application-Id Operator toEquals and theValue to 4. For all other parameters, set theOperator to Always True.
