Shared and Default iFCs

The Oracle Communications Unified Session Manager supports Shared iFCs (SiFC), as defined by TS 29.229 and Default iFCs, which are an Oracle extension upon SiFCs. SiFCs provide an operator with the ability to create iFC templates and apply them to a large number of UEs. The SiFC process optimizes the provisioning, storage and transfer of service profile information. The default IFC (DiFC) establishes a configuration wherein the iFC associations are available on the Oracle Communications Unified Session Manager itself. This establishes a backup scenario in case the HSS is not responsive.

To support the SiFC feature on the Oracle Communications Unified Session Manager, you create a profile that refers to a local, XML-formatted file. This file specifies the iFCs to be shared. You apply these profiles to registrars to specify where they are used.

When an SiFC configuration is in place, the Oracle Communications Unified Session Manager notifies the HSS that it supports SiFCs within the Supported-Features AVP in the SAR. The HSS replies to confirm that it supports SiFCs within the SAA. The SiFC feature must be enabled on the HSS.

Note that the form and function of the SiFC and DiFC files are compatible. You can use the same file for both SiFC and DiFC configuration, if desired.
