Question: How does a User Equipment (UE) in an Evolved Packet System (EPS) typically signal its supported positioning methods to the core network during initial setup?
Option 1: Using Classmark3 in CS mode, as specified for GSM.
Option 2: Through LPP (Location Positioning Protocol) by the initial location service invocation.
Option 3: Exclusively within UTRAN, without direct signaling to the core network.
Option 4: Via MS Network Capability in PS mode only for privacy invocation.
Explanation: In an EPS (Evolved Packet System), the UE signals its supported positioning methods to the core network using LPP (Location Positioning Protocol) during the initial location service invocation, as opposed to other modes or systems where different signaling methods are used. This method is specific to EPS for positioning capabilities exchange, highlighting the system's unique operational protocols for location services.
