Question: In an LTE network, when an NB-IoT UE requests location assistance data for positioning, what consideration may an E-SMLC apply based on the UE's state and capabilities?
Option 1: Always prioritize low-power mode for all UEs to conserve energy.
Option 2: Apply standard QoS without adjustments for any UE type or state.
Option 3: Consider the UE's access type but not its current state (e.g., ECM-IDLE) for QoS adjustments.
Option 4: Allow additional response time in the QoS if aware the NB-IoT UE is in ECM-IDLE state, to facilitate measurement collection.
Explanation: This option is correct because an E-SMLC aware of an NB-IoT UE being in ECM-IDLE state may adjust the QoS by allowing additional response time, supporting the UE in successfully obtaining necessary measurements for location services without timing out.
