Question: In a Mission Critical Data (MCData) scenario, what are the possible ways to cancel an in-progress emergency group state for a group, according to 3GPP specifications?
Option 1: Only through the group's Functional Alias (FA) de-registration process.
Option 2: Exclusively by the emergency alert cancellation procedure from a related Mission Critical Service specification.
Option 3: Through either the group FD in-progress emergency state cancellation procedure or the emergency alert cancellation procedure specified in another relevant 3GPP TS for mission critical services.
Option 4: Automatically upon group member's User Equipment (UE) handover to a different network.
Explanation: Cancelling an in-progress emergency group state can be achieved through two procedures: the group FD in-progress emergency state cancellation procedure, or the emergency alert cancellation procedure detailed in another 3GPP specification for mission critical services, highlighting flexibility and redundancy in managing emergency states within MCData scenarios.
