Question: During an Access Transfer procedure in IMS Service Continuity, what happens to the Source Access Leg if the UE retains some media flow(s) in the transferred-out access but fails to update this information?
Option 1: The Source Access Leg is updated automatically by the ATCF to reflect the retained media flows.
Option 2: The SCC AS releases the Source Access Leg and updates the Remote Leg accordingly.
Option 3: The Access Transfer procedure is aborted, and the UE must reinitiate the process.
Option 4: The ATGW anchors the media to prevent any disruption until the update is made.
Explanation: According to IMS Service Continuity procedures, if the UE chooses to retain some media flows in the transferred-out access but fails to update this information, the SCC AS will release the Source Access Leg to maintain service continuity and consistency, ensuring efficient resource management and correct Remote Leg updates.
