Question: In E-UTRAN's Standalone mode for User Equipment (UE) positioning, what additional information is the UE expected to report alongside its geographical coordinates (latitude, longitude, and possibly altitude)?
Option 1: Signal Strength of serving cell and neighboring cells
Option 2: Indication of WLAN method and possibly other positioning methods used
Option 3: Velocity vector and direction of movement
Option 4: Battery life and UE device type
Explanation: In the context of precise location services, understanding the positioning methods (e.g., WLAN, GPS, etc.) utilized by the UE is crucial for assessing the accuracy and reliability of the reported geographical coordinates. This information helps the network to better evaluate the location uncertainty estimate provided by the UE, ensuring more effective location-based services and emergency response systems.
