Abstract

Quality of Service (QoS) is mandatory in next-generation mobile networks (beyond 5G and 6G) to support enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communication (URLLC), and Massive MachineType Communication (mMTC) in an Open Radio Access Network (Open RAN). However, the complexity of managing these networks increases the likelihood of configuration errors, leading to QoS degradation. This paper proposes an intent-based system where operators control resource allocation through natural language expressions translated into network policies for dynamic bandwidth control. The system is validated in an emulated environment, OpenFlow meters, and traffic queues. The results demonstrate efficient resource allocation and compliance with Service Level Agreements (SLAs), ensuring QoS and traffic prioritization for flows.
