Question: In a PCC (Policy and Charging Control) scenario for Emergency Services, what is the expected behavior if a PCEF (Policy and Charging Enforcement Function) includes a 'RESOURCE_MODIFICATION_REQUEST' Event-Trigger AVP in its request?
Option 1: The PCRF (Policy and Charging Rules Function) will process the request with priority.
Option 2: The PCRF will reject the request with a DIAMETER_ERROR_TRAFFIC_MAPPING_INFO_REJECTED error.
Option 3: The PCEF will retry the request without the Event-Trigger AVP after a short timeout.
Option 4: The request will be queued for later processing when resources are available.
Explanation: According to specified behavior for PCC Rules related to Emergency Services, if a PCEF-initiated request includes the 'RESOURCE_MODIFICATION_REQUEST' Event-Trigger AVP, the PCRF is mandated to reject this request. The rejection reason is specifically tied to traffic mapping information, highlighting the importance of adhering to defined protocols for emergency services to ensure proper handling and resource allocation.
