Question: In E-UTRAN, how can dedicated priorities for inter-frequency/inter-RAT cell reselection be set for individual UEs at specific states?
Option 1: Through broadcasting a common priority valid for all UEs in a given cell.
Option 2: Via dedicated signalling from the eNB to the UE during RRC_IDLE state only.
Option 3: Based on UE's current cell ID and signal strength, determined by the UE itself.
Option 4: Through dedicated signalling from E-UTRAN to individual UEs at RRC_CONNECTED to RRC_IDLE transition, potentially based on subscription related information.
Explanation: This is correct because E-UTRAN can overwrite common priorities with dedicated signalling for individual UEs specifically during the transition from RRC_CONNECTED to RRC_IDLE. Moreover, these dedicated settings can be influenced by subscription-related information, aligning with operator policies, allowing for personalized and dynamic management of UE mobility based on both network and subscriber factors.
