Question: In a roaming scenario with PCC deployment only in the Home Public Land Mobile Network (HPLMN) and not in the Visited Public Land Mobile Network (VPLMN), using a Gateway (BBERF), what action does the Online Charging System (OCS) take regarding re/authorization triggers that require event reporting?
Option 1: The OCS sets additional re/authorization triggers to compensate for the lack of event reporting from the VPLMN.
Option 2: The OCS ignores the roaming agreements and sets re/authorization triggers as if PCC were fully deployed.
Option 3: The OCS does not set re/authorization triggers that would require event reporting which cannot be generated due to limited PCC deployment.
Option 4: The OCS relies on the H-PCRF to generate the necessary event reports from other network elements.
Explanation: In a scenario where PCC is not fully deployed across both HPLMN and VPLMN, and relying on a Gateway (BBERF), the Online Charging System (OCS) must adapt to the limitations in event reporting. Since some events cannot be reported from the VPLMN due to the absence of PCC deployment, the OCS avoids setting triggers that would necessitate such unobtainable reports. This ensures the charging and policy control processes operate within the bounds of available network capabilities, preventing potential disruptions or inaccuracies in billing and resource allocation.
