Question: What is the primary purpose of the Transmission/Reception Control functional entity in Mission Critical Data (MCData) communications, as per 3GPP standards?
Option 1: To manage voice call prioritization between MCData clients and servers.
Option 2: To handle authentication protocols for secure data exchange.
Option 3: To provide arbitration between multiple data requests and ensure appropriate IP Data transmission based on applied policies.
Option 4: To optimize video streaming quality over wireless networks.
Explanation: In the context of MCData communications, the Transmission/Reception Control entity manages the flow of IP data. Its primary function is to arbitrate multiple simultaneous data requests, ensuring correct policy application for IP data transmission between clients and servers, maintaining mission-critical communication integrity and reliability.
