Enhancing energy efficiency in 5G networks through AI-driven dynamic discontinuous reception
With the accelerated rollout of 5G networks comes a dramatic explosion of data rates for numerous applications, accompanied by explosive energy consumption in User Equipment (UE). This paper proposes AI-DRX: an artificial intelligence (AI) powered Dynamic Discontinuous Reception (DRX) mechanism for energy saving in 5G networks. We present a data-driven approach that utilizes Convolutional Neural Networks (CNNs) specifically optimized for real-time operation on mobile devices to model the complex relationship between DRX parameters, network conditions, and user behavior patterns. The proposed AI-DRX mechanism optimizes DRX parameters according to real-time conditions, enabling significant energy savings with minimal QoS degradation. Using comprehensive evaluation with real wireless traffic traces from the MONROE dataset, the AI-DRX mechanism demonstrates energy savings of 69.2% and 55.8% compared to traditional LTE-DRX across different network scenarios, and 70% improvement over Poisson packet arrival models. The CNN model achieves 91.8% prediction accuracy with inference latency of only 2.3ms on modern mobile hardware, making real-time deployment feasible. These results emphasize the promising impact of AI-DRX on dramatically increasing energy efficiency in 5G-powered devices, marking it as an integral component for ensuring sustainable performance of next-generation mobile networks.

The AI-DRX mechanism is a novel AI-driven Dynamic Discontinuous Reception system designed to optimize energy consumption in 5G networks. It uses a CNN-based architecture to predict optimal DRX parameters in real-time, adapting to network conditions and user behavior. This ensures significant energy savings while maintaining Quality of Service (QoS).
Our comprehensive evaluation, utilizing real wireless traffic traces from the MONROE dataset, demonstrates AI-DRX's superior energy efficiency. It achieves up to 69.2% energy savings compared to traditional LTE-DRX, maintains a low delay violation rate of 0.34%, and exhibits a CNN prediction accuracy of 91.8% with only 2.3ms inference latency.
AI-DRX is designed for practical deployment, addressing hardware constraints, protocol stack integration, and security concerns. It employs model quantization, pruning, and knowledge distillation for mobile deployment. A federated learning approach ensures privacy and continuous adaptation, with a clear roadmap for pilot to commercial rollout.
