Question: In an NG-RAN, what is the primary purpose of the LTE Positioning Protocol (LPP) when operating between a target device and a positioning server?
Option 1: To manage user-plane protocols for voice calls in LTE networks.
Option 2: To enable seamless handover between LTE and NR (5G) networks.
Option 3: To secure data transmission over the NG-C interface using NAS/RRC.
Option 4: To facilitate positioning for both NR and LTE using various position methods, isolating method details from underlying transport specifics.
Explanation: The correct answer is Option 4 because LPP supports multiple positioning methods (e.g., cell ID, OTDOA, E-CID) for both LTE and NR networks while decoupling the positioning logic from the specifics of the transport layer, allowing for flexible and method-agnostic positioning capabilities in NG-RAN.
