UNITY-6G partners Jorge Baranda, Albert Bel, Sergio Barrachina-Muñóz, Miquel Payaró, and Josep Mangues-Bafalluy have published a research paper at IEEE INFOCOM 2025, held from May 19–22 in London, UK. The paper, titled “End-to-End Slice Orchestration in a 5G Cloud-Native Mobile Network with O-RAN Split 7.2,” presents an innovative approach to flexible and disaggregated network deployments using open-source software and commercial equipment.
Abstract
The adoption of novel network paradigms in the architecture and management of mobile networks is accelerating its evolution. In this demonstration, we contribute to the cloudnative mobile network orchestration domain by presenting an end-to-end system allowing the disaggregated and distributed deployment of mobile network entities from core to RAN based on open-source software. The distinguishing features of this system are the possibility of enabling the configuration of slices that can be later activated on-demand and the use of O-RAN Split
7.2 for over-the-air transmission using commercial equipment.
Keywords—Cloud-native networks, network slicing, 5G, O-RAN, mobile orchestration, open-source
This work aligns closely with UNITY-6G’s ambition to enable intelligent, flexible, and interoperable next-generation mobile networks. By showcasing a practical, end-to-end orchestration approach, the authors contribute to the ongoing evolution toward cloud-native architectures and disaggregated RAN solutions.
