Question: What is the expected system response when a User Equipment (UE) successfully selects an alternative profile on a per-call basis using a specified MMI command?
Option 1: The UE displays a confirmation message indicating the new profile is active.
Option 2: Continued processing of the call implicitly indicates successful selection, with no explicit user notification.
Option 3: The network sends a dedicated signal to the UE to confirm the alternative profile activation.
Option 4: The UE automatically restarts to apply the changes from the newly selected profile.
Explanation: According to telecom principles for User Equipment (UE) interactions, especially in selecting alternative profiles during call setup, implicit confirmations are often used to streamline processes. The successful continuation of the call setup process serves as an implicit indication that the alternative profile selection was executed correctly, aligning with efficient and seamless user experience design in telecommunications, avoiding unnecessary interruptions or additional signaling, focusing on service continuity.
