Question: In IMS sessions established by UEs via the I2 reference point, what is the primary role of the MSC Server enhanced for ICS regarding Communication Diversion (CDIV) services?
Option 1: To perform interworking between the I2 reference point and CS signalling to enable CDIV execution in the IMS.
Option 2: To directly handle all CDIV requests without needing CS signalling interworking.
Option 3: To act solely as a proxy, forwarding CDIV requests to an external server for processing.
Option 4: To manage CDIV services exclusively for UEs connected via other reference points.
Explanation: The MSC Server enhanced for ICS plays a crucial role in facilitating Communication Diversion services by translating or interworking between the IP-based I2 interface and traditional Circuit Switched signalling, ensuring seamless integration of IMS services with legacy CS functionalities for effective CDIV service execution.
