SON Base Station Energy Saving via RRC and PRBU Monitoring

The patent applies dynamic power adjustment by transitioning base stations between active and sleep states based on real-time traffic conditions. The controller monitors RRC connection counts and PRBU metrics, dynamically switching base stations to energy-saving mode when traffic is low while maintaining service capacity when needed, thus resolving the contradiction between service capacity and power consumption.

The patent changes operational parameters of base stations by adjusting power consumption levels based on traffic load. When RRC connection count and PRBU fall below thresholds, base stations are parameter-changed to sleep state with reduced power consumption. When thresholds are exceeded, parameters are adjusted to active state, balancing service capacity requirements with energy efficiency.

The patent implements feedback mechanisms where the controller continuously monitors RRC connection counts, PRBU, and traffic patterns to determine optimal power adjustment timing. This feedback loop ensures base stations are activated before service quality deteriorates and deactivated when traffic is sufficiently low, maintaining service quality while reducing power consumption.

The patent applies preliminary action by predicting future traffic patterns and proactively adjusting base station power states before service quality degradation occurs. The controller uses historical data and thresholds to anticipate traffic spikes and pre-activates base stations, preventing service quality deterioration while maximizing energy savings during low-traffic periods.
