Question: What is the purpose of the function that enables requesting a change of handover and/or reselection parameters at the target cell?
Option 1: To optimize network performance during peak hours.
Option 2: To adapt mobility configuration in response to changes in user behavior.
Option 3: To ensure seamless handovers between cells with different frequencies.
Option 4: To balance load between cells and prevent congestion.
Explanation: The function is used to adapt handover and/or reselection parameters at the target cell to balance load between cells and prevent congestion. This is evident from the text, which states that the source cell estimates if it is needed to change mobility configuration in the source and/or target cell for load balancing related requests.
