Question: What type of information does the Core Network provide to aid RAN optimization in a 5G system?
Option 1: UE location and velocity
Option 2: Core Network assisted RAN parameters tuning and Core Network assisted RAN paging information
Option 3: UE battery level and signal strength
Option 4: Network congestion and available resources
Explanation: The Core Network provides assistance information to the RAN, which includes two types of information sets: Core Network assisted RAN parameters tuning and Core Network assisted RAN paging information. This information helps the RAN optimize UE state transition steering, RRC state transition decision, and formulate an optimized paging strategy when RAN paging is triggered.
