Question: In a Mission Critical Data (MCData) environment, when initiating a one-to-one standalone short data service (SDS) using the signaling control plane, how is the target MCData user typically addressed?
Option 1: Using a unique IP Address that is exclusive to each MCData user.
Option 2: Through a functional alias that can be shared with other MCData users for discovery.
Option 3: By employing a dynamic DNS service that updates records in real-time.
Option 4: Utilizing the IMSI (International Mobile Subscriber Identity) of the target user.
Explanation: In the context of MCData, especially for one-to-one standalone short data services via the signaling control plane, addressing simplicity and efficiency are crucial. A functional alias, which can be shared among users to facilitate easy identification and connection, is the most suitable method for initiating such a service. This approach aligns with the need for streamlined communication in mission-critical scenarios where every moment counts.
