Question: Which entity facilitates signaling access between a Location Management Function (LMF) and an NG-RAN node for broadcasting assistance data information?
Option 1: Serving Gateway (S-GW)
Option 2: Packet Data Network Gateway (P-GW)
Option 3: Mobility Management Entity (MME)
Option 4: Access and Mobility Management Function (AMF)
Explanation: The correct answer is the Access and Mobility Management Function (AMF) because, according to the specified telecom concept, signaling access between the Location Management Function (LMF) and an NG-RAN node for broadcasting assistance data (including positioning System Information Blocks and metadata) is facilitated via any AMF that has signaling access to both the LMF and the NG-RAN node. This highlights the AMF's role in managing mobility and access, including facilitating communication between different network functions for efficient data exchange in 5G networks.
