Question: In a Collaborative Session with UE-1 as Controller UE and UE-2 as Controllee UE, what happens to the Access Leg between UE-2 and the SCC AS if no more media flow remains after transferring Media-A to UE-1?
Option 1: The Access Leg is modified to support future media flows from UE-1.
Option 2: The Access Leg between UE-2 and the SCC AS is released, removing UE-2 from the Collaborative Session.
Option 3: The Access Leg's bandwidth is reduced to a minimal state for potential future use.
Option 4: The Access Leg is put into a dormant state, awaiting reactivation by UE-1.
Explanation: Once Media-A is successfully transferred from Controllee UE (UE-2) to Controller UE (UE-1) and no other media flows remain on the access leg between the SCC AS and UE-2, the Access Leg between UE-2 and the SCC AS is released, removing UE-2 from the Collaborative Session.
