Question: Over the Sd reference point for unsolicited application reporting, which procedure applies for requesting TDF (Traffic Detection Function) Session Termination, considering a dual-stack scenario?
Option 1: The procedure described with an exemption for releasing the IPv4 address, notified via Session Termination.
Option 2: Sequential procedures for TDF Session setup and then termination.
Option 3: A bespoke procedure specifically designed for dual-stack scenarios, not described in standard referenced procedures.
Option 4: No specific procedure is defined for TDF Session Termination over Sd in a dual-stack context.
Explanation: This requires understanding of telecom network management, particularly Policy and Charging Control (PCC) as per 3GPP standards. The correct answer highlights the specific procedure for TDF Session Termination with a notable exemption for handling IPv4 addresses in dual-stack scenarios, demonstrating nuanced understanding of network protocol adaptations for different IP address configurations.
