Question: In a multi-access IP-CAN session, what is the primary purpose of the Removal-Of-Access AVP as utilized by the Policy and Charging Rules Function (PCRF)?
Option 1: To indicate the removal of one access from the multi-access IP-CAN session.
Option 2: To add a new access to an existing single-access IP-CAN session.
Option 3: To modify the QoS parameters for all accesses in a multi-access IP-CAN session.
Option 4: To request a status update of all active IP-CAN sessions.
Explanation: The Removal-Of-Access AVP is specifically designed to facilitate the removal of one access from a multi-access IP-CAN (Internet Protocol Connectivity Access Network) session, as directed by the PCRF. This functionality is crucial for dynamically managing and adjusting network resources and user connectivity in real-time, based on policy and charging rules.
