Question: What is the primary purpose of the SEAL-PC5 reference point in the context of Service Enabler Architecture Layer for Verticals (SEAL)?
Option 1: To facilitate direct interactions between User Equipment (UE) of different Vertical Applications (VAL) for service enablement.
Option 2: To establish a communication link between the SEAL server and a single UE for vertical service provisioning.
Option 3: To define the interface between the SEAL layer and the underlying network infrastructure for QoS management.
Option 4: To specify the protocol for billing and charging information exchange between VALs and the SEAL platform.
Explanation: The SEAL-PC5 reference point is used for direct interactions between SEAL clients of two different Vertical Applications (VAL) User Equipment (UE), enabling services across UEs of different VALs through peer-to-peer communication.
