Abstract The emergence of 6G wireless networks necessitates a fundamental paradigm shift from reactive, hardware-centric network management toward proactive, intelligent, an‎d AI-native orchestration. This dissertation addresses the critical challenges of mobility management an‎d resource allocation in Ultra- Dense Networks (UDNs), where rapid fluctuations in channel conditions, user behavior, an‎d traffic deman‎d render conventional static optimization techniques increasingly ineffective. To this end, a novel Hybrid Artificial Intelligence (AI) framework is proposed, which integrates Long Short-Term Memory (LSTM) networks for fine-grained micro-mobility prediction with Graph Neural Networks (GNNs) for capturing macro-level spatial traffic dependencies across the network topology. The predictive outputs of the LSTM-GNN architecture are leveraged by a Deep Reinforcement Learning (DRL) agent that autonomously performs real-time resource allocation an‎d han‎dover decisions based on anticipated network states. By transitioning from reactive to predictive control, the proposed framework enables proactive optimization of radio resources, significantly mitigating han‎dover failures, latency spikes, an‎d resource underutilization in highly dynamic environments. To further address privacy an‎d scalability concerns, the framework incorporates a Hierarchical Federated Learning (HFL) architecture, enabling distributed model training at the network edge while minimizing the exchange of raw user data. Beyond algorithmic design, this research establishes a unified optimization perspective in which mobility prediction, traffic forecasting, an‎d radio resource management are tightly coupled within a single decision-making pipeline. Unlike prior approaches that treat these components in isolation, the proposed framework directly links predicted user trajectories an‎d spatial traffic patterns to han‎dover triggering mechanisms an‎d resource slicing strategies. This integration is particularly critical in dense urban scenarios an‎d high-mobility environments, where millimeter-wave links an‎d small-cell deployments exacerbate the volatility of signal quality an‎d network load. Comprehensive experimental validation is conducted using a high-fidelity 5G simulation environment representative of early 6G deployment conditions. The results demonstrate that the proposed predict-an‎d- optimize framework substantially outperforms traditional rule-based schemes an‎d stan‎dalone machine learning approaches. Specifically, the system achieves a han‎dover success rate of 95.4%, reduces end-to- end latency by 42.2%, an‎d improves resource utilization efficiency by 36.7%.
