Question: What is the primary principle guiding the separation of NG-RAN and transport functions in the 5G architecture?
Option 1: Integration of signalling and data transport networks
Option 2: Shared addressing schemes between NG-RAN, 5GC, and transport functions
Option 3: Logical separation of signalling and data transport networks with separate addressing schemes
Option 4: Merging of NG-RAN and transport functions into a single entity
Explanation: The correct answer is based on the principle that NG-RAN and 5GC functions are fully separated from transport functions, and their addressing schemes should not be tied to those of transport functions. This ensures a clear distinction between the logical separation of signalling and data transport networks, which is essential for the scalability and flexibility of the 5G architecture.
