Abstract

The centralization and global monopoly of mobile network operators pose significant barriers to the advancement of 6G networks, limiting the flexibility and interoperability required to meet next-generation advanced service demands. The concept of network slicing emerges as a promising approach to address these challenges, enabling the creation of configurable slices tailored to different requirements. This paper introduces SLOrion, a decentralized solution based on smart contracts and Distributed Ledger Technology. The proposed solution automates the translation of Service Level Agreements into technical parameters for network slicing as a service, reducing manual intervention, promoting interoperability, and ensuring the integrity of network configurations. SLOrion addresses existing gaps in the literature by directly linking smart contracts to the technical configurations of mobile networks, contributing to the democratization of 6G networks. The results show that SLOrion maintains over 90% accuracy and a response time up to a thousand times faster than the OpenAI model, ensuring scalability for 5G and 6G networks.
