Question: Which capability is utilized to support 'off-network' Enhanced Status for Mission Critical Data (MCData) services, as per 3GPP standards?
Option 1: Proximity Services (ProSe) capabilities
Option 2: Device-to-Device (D2D) Communication capabilities
Option 3: LTE Broadcast (eMBMS) capabilities
Option 4: IMS (IP Multimedia Subsystem) Emergency Services capabilities
Explanation: Enhanced Status for off-network Mission Critical Data services relies on Proximity Services (ProSe) capabilities, which enable direct communication between devices without relying on the traditional network infrastructure. This is crucial for mission-critical communications that must function even when the regular network is unavailable or congested, ensuring seamless operation and coordination among first responders or critical service teams in the field.
