Question: During IP-CAN session establishment, what action does the PCRF take regarding NBIFOM support if it determines that NBIFOM does not apply to the IP-CAN session?
Option 1: The PCRF sets the NBIFOM-Support AVP to the value NBIFOM_SUPPORTED (1) and selects an applicable NBIFOM mode.
Option 2: The PCRF sets the NBIFOM-Support AVP to the value NBIFOM_NOT_SUPPORTED (0).
Option 3: The PCRF omits including the NBIFOM-Support AVP in the CCA command.
Option 4: The PCRF requests additional UE data before making a decision on NBIFOM support.
Explanation: When the Policy and Charging Rules Function (PCRF) decides that Network-Based Individual Flow Optimization and Mobility (NBIFOM) does not apply to an IP Connectivity Access Network (IP-CAN) session, it explicitly communicates this decision by setting the NBIFOM-Support Attribute Value Pair (AVP) to NBIFOM_NOT_SUPPORTED (0) in the CCA command, informing the Policy and Charging Enforcement Function (PCEF) of the policy decision.
