Question: In a non-seamless WLAN offload (NSWO) scenario, what is the primary purpose of the session binding step performed by the Policy and Charging Rules Function (PCRF) for AF and TDF sessions to an IP-CAN session?
Option 1: To enable seamless handover between cellular and WLAN networks.
Option 2: To prioritize traffic based on subscriber identity.
Option 3: For policy control in the Broadband Forum (BBF) domain.
Option 4: To dynamically adjust QoS parameters for video streaming.
Explanation: In non-seamless WLAN offloading, session binding is crucial for integrating policy decisions across different network domains. By binding AF and TDF sessions to an IP-CAN session, the PCRF ensures policy control in the Broadband Forum (BBF) domain, managing resources and enforcing policies in a WLAN offload scenario, highlighting coordinated policy management's importance across heterogeneous networks for efficient traffic handling.
