Question: What happens when a dispatcher, entitled to terminate a Voice Group Call Service (VGCS) call, simply disconnects from the call without using explicit signalling?
Option 1: The entire VGCS call is automatically terminated for all participants.
Option 2: The dispatcher's disconnection triggers a notification to all remaining participants.
Option 3: The call continues uninterrupted among the remaining participants; only the dispatcher is disconnected.
Option 4: The system automatically promotes another participant to assume the dispatcher role.
Explanation: According to VGCS principles, a dispatcher can leave (disconnect from) a call at any time without affecting the ongoing call among other participants. Explicit signalling is required only when the intention is to terminate the entire call for all participants. Thus, in this scenario, the call continues uninterrupted among the remaining participants, with only the dispatcher being disconnected.
