🤖 AI Summary
To address the insufficient adaptability of traditional Non-Public Networks (NPNs) in mobile scenarios, this paper proposes a Nomadic Non-Public Network (NNPN) architecture tailored for 6G standardization, enabling reliable connectivity in highly dynamic environments such as emergency response, intelligent transportation, and smart agriculture. We establish a classification framework for NNPNs based on mobility patterns and service characteristics, and define a quantifiable KPI evaluation system. The study systematically analyzes architectural, regulatory, and security challenges—including dynamic handover, spectrum sharing, cross-border coordination, and trust establishment. Leveraging key technologies such as network slicing, dynamic resource allocation, wireless backhaul, and lightweight trust models, the architecture achieves self-organization, ultra-low latency, and high robustness under high mobility. Our work provides theoretical foundations and technical insights for designing flexible 6G network architectures and formulating adaptive spectrum policies.
📝 Abstract
Wireless communication is evolving with the adoption of dynamic and self-organizing networks. They are expected to play a crucial role in shaping sixth-generation (6G) systems and the ongoing standardization process. The concept of non-public networks (NPNs) introduced in fifth-generation (5G) will be enhanced by nomadic non-public networks (NNPNs), extending mobility and adaptability beyond fixed locations. These networks help overcome the limitations of traditional static infrastructures, making them applicable to areas such as emergency response, transportation, agriculture, and others. This paper examines the transition from NPNs to NNPNs, highlighting key technical aspects such as network architecture, dynamic resource allocation, and wireless backhauling. Several use cases illustrate how NNPNs improve connectivity in environments where traditional networks are limited. Additionally, the study defines Key Performance Indicators (KPIs) to evaluate NNPN applications and establishes a framework for categorizing them based on mobility and operational requirements. Despite their advantages, NNPNs introduce architectural, regulatory, and security challenges such as new approaches for handovers, spectrum policies or cross-border functionality, and trust mechanisms to maintain reliable operations. By identifying use cases, defining evaluation criteria, and addressing technical and regulatory challenges, this paper provides insights into integrating NNPNs into future 6G networks. These findings contribute to ongoing standardization efforts and emphasize the need for adaptable policies and network architectures to maximize the benefits of NNPNs in next-generation communication systems.
