Question: What is the primary purpose of Non-UE Associated LPPa Transport procedures in E-UTRAN?
Option 1: To support handover decisions for UEs moving between eNodeBs.
Option 2: To obtain assistance data from an eNodeB for OTDOA (Observed Time Difference of Arrival) positioning for any UE.
Option 3: To manage QoS (Quality of Service) parameters for UE-associated services.
Option 4: To facilitate direct communication between UEs in proximity.
Explanation: Non-UE Associated LPPa Transport procedures are utilized to gather assistance data from an eNodeB, crucial for supporting OTDOA positioning. This method does not target a specific UE but rather enables location services for any UE within the network, leveraging the eNodeB's observational capabilities, enhancing location accuracy and availability across the E-UTRAN network.
