Question: In the LTE Positioning Protocol (LPP), what is the primary purpose of supporting multiple positioning methods and hybrid positioning, where two or more position methods are used concurrently?
Option 1: To reduce signaling overhead between the target device and the positioning server.
Option 2: To enable backward compatibility with legacy access technologies like UTRAN and GERAN.
Option 3: To enhance security for location-related services by diversifying positioning data sources.
Option 4: To improve the accuracy of location estimates and support various Quality of Service (QoS) requirements.
Explanation: The correct answer highlights the key benefit of LPP's support for multiple and hybrid positioning methods. By concurrently utilizing two or more position methods, LPP can provide more accurate location estimates and cater to diverse QoS requirements, crucial for various location-based services in LTE networks.
