Question: In UE-assisted mode for E-UTRAN positioning, what is the primary purpose of the UE reporting barometric pressure sensor measurements to the E-SMLC?
Option 1: To enhance horizontal location accuracy by providing additional cell ID information.
Option 2: To enable the E-SMLC to calculate the vertical component of the UE's location.
Option 3: To support handover decisions based on atmospheric pressure changes.
Option 4: To provide input for weather forecasting services integrated with the telecom network.
Explanation: The correct answer highlights the key role of barometric pressure sensor measurements in determining the vertical (altitude) aspect of a UE's location, crucial for precise positioning, especially in areas with significant elevation differences. The E-SMLC utilizes these measurements to calculate this vertical component accurately.
