Question: What is expected to happen to all traffic on a cell before it transitions from 'notEnergySaving' state to 'energySaving' state, to prevent coverage holes or undue load on surrounding cells?
Option 1: The traffic is automatically redirected to the cell's umbrella cells after the transition.
Option 2: The cell's capacity is reduced to handle only low-priority traffic.
Option 3: Nearby cells adjust their transmission power to compensate for the transitioning cell.
Option 4: All traffic on that cell is drained to other overlaid/umbrella candidate cells before the transition.
Explanation: To maintain network integrity and prevent coverage issues, it's crucial that all traffic is safely redirected to other capable cells (overlaid/umbrella candidate cells) before a cell enters an energy-saving state. This ensures seamless service continuity for users and prevents undue load on surrounding cells, aligning with the principles of efficient network management and energy conservation as outlined in telecom best practices for energy efficiency.
