Question: Which of the following best describes the primary consideration for Connection Mobility Control (CMC) in idle mode for a User Equipment (UE)?
Option 1: Handover decisions based on UE and eNB measurements.
Option 2: Management of transport and hardware resources within the E-UTRAN.
Option 3: Application of Operator-defined policies for traffic distribution.
Option 4: Setting of cell reselection parameters (thresholds and hysteresis values) for determining the best cell.
Explanation: In idle mode, the key aspect of Connection Mobility Control (CMC) is to ensure the UE selects the most appropriate cell based on predefined criteria. This is achieved by configuring the UE with specific parameters that dictate when to select a new cell, emphasizing the importance of thresholds and hysteresis values in this process. These settings directly influence the cell reselection algorithm, making Option 4 the correct answer.
