Question: In a multi-access IP-CAN session, how does the PCEF associate PCC rules with the allowed access within the IP-CAN session for NBIFOM (Non-Seamless WiFi Offload with Mobility)?
Option 1: By dynamically creating new PCC rules for each access type.
Option 2: The allowed access may be either explicitly included in the PCC Rule or the default NBIFOM access for the traffic on the IP-CAN session.
Option 3: Through direct negotiation with the UE to determine access preferences.
Option 4: By prioritizing accesses based on signal strength and associating rules accordingly.
Explanation: This is correct because, according to PCEF procedures for NBIFOM in multi-access IP-CAN sessions, the association of PCC rules with allowed access can be done in two ways: either the allowed access is explicitly listed within the PCC Rule itself or it defaults to the NBIFOM access designated for the traffic on that particular IP-CAN session. This approach ensures flexibility and efficiency in managing multiple accesses within a single session.
