Question: In a Voice Group Call Service (VGCS) scenario, when a user receives details of a voice group call in a congested cell where pre-emption did not occur, what determines if the mobile station automatically moves to the notified call?
Option 1: The new call's priority level being higher than the existing call and automatic acceptance applying for this priority level.
Option 2: The user's current location within the cell (e.g., proximity to the cell edge).
Option 3: The type of subscription the user has (e.g., premium or standard).
Option 4: The time of day when the voice group call is received.
Explanation: In VGCS, the automatic movement of a mobile station to a notified call in a congested cell, where pre-emption didn't occur, hinges on two key factors: (1) the new call must have a higher priority than the existing call, and (2) automatic acceptance must be configured for this specific priority level. This ensures that only high-priority calls can override existing connections in congested conditions when pre-emption is not possible, maintaining service quality for critical communications.
