TL;DR
This paper addresses the need to modernize mobile network management by leveraging heterogeneous radio access technologies (RATs) through Digital Twins (DTs) and integrating GenAI-enabled analytics. It proposes a modular DT framework with End-Devices, Signal Handler, Twin Instance Controller, and Network Twin Console, using an MQTT event bus to enable real-time data flow and interoperability across platforms. The authors validate the approach in the UbiKampus Campus Area Network, demonstrating real-time, multi-RAT insights and the potential for AI-driven, descriptive-to-prescriptive analytics to optimize network and environment management. They also discuss the opportunities and challenges of interoperability, standardized data models, and GenAI integration, outlining a roadmap toward scalable, multi-platform DT deployments in future networks.
Abstract
Digital Twins (DTs) are set to become a key enabling technology in future wireless networks, with their use in network management increasing significantly. We developed a DT framework that leverages the heterogeneity of network access technologies as a resource for enhanced network performance and management, enabling smart data handling in the physical network. Tested in a Campus Area Network environment, our framework integrates diverse data sources to provide real-time, holistic insights into network performance and environmental sensing. We also envision that traditional analytics will evolve to rely on emerging AI models, such as Generative AI (GenAI), while leveraging current analytics capabilities. This capacity can simplify analytics processes through advanced ML models, enabling descriptive, diagnostic, predictive, and prescriptive analytics in a unified fashion. Finally, we present specific research opportunities concerning interoperability aspects and envision aligning advancements in DT technology with evolved AI integration.
