Question: In E-UTRAN, what is the primary purpose of the Barometric Pressure Sensor Location Information Transfer Procedure between the UE and the E-SMLC (Evolved Serving Mobile Location Centre)?
Option 1: To facilitate handover decisions based on atmospheric pressure changes.
Option 2: To enable the transfer of barometric pressure sensor measurements for UE position calculation, either by E-SMLC request or UE initiative for self-location.
Option 3: To optimize network coverage by adjusting cell tower transmission power according to weather conditions.
Option 4: To provide subscribers with real-time weather forecasts based on collective barometric data from UEs.
Explanation: This option correctly captures the essence of the procedure, highlighting its role in positioning (location calculation) using barometric pressure sensor measurements. This is crucial for determining a UE's location, especially in scenarios where traditional methods may not be effective or accurate enough.
