Abstract

This paper reports part of the ongoing work being carried out in the scope of the SliceNet project, a vertical business-driven H2020 project in which 5G technologies and services are being developed with the specific goal of serving a heterogeneous set of vertical applications. Efacec and Altice Labs are contributing with a vertical business use case focused on communication-based protection and automation solutions for medium voltage (MV) energy distribution networks. The use case includes the implementation and testing of several distributed algorithms, including high-speed selective blocking using IEC 61850 Routable-Generic Object Oriented Substation Events (R-GOOSE), high-speed post-fault service restoration using R-GOOSE, and differential protection using Phasor Measurement Unit (PMU) data transmitted over R-GOOSE. The paper reports on the first stage of lab-based trials that are currently being carried out in the use case testbed, consisting mainly of R-GOOSE communication resilience and high-speed selective blocking over 5G. A small set of the lab tests aim at providing early results for a future viability assessment of the implementation of a differential protection solution over 5G. The results from phase-one trials will be disclosed and analysed, and the plan for the ensuing use case trial stages will be subsequently presented.

Article
Media use cases for emergency services require mission-critical levels of reliability for the delivery of media-rich services, such as video streaming. With the upcoming deployment of the fifth generation (5G) networks, a wide variety of applications and services with heterogeneous performance requirements are expected to be supported, and any migration of mission-critical services to 5G networks presents significant challenges in the quality of service (QoS), for emergency service operators. This paper presents a novel SliceNet framework, based on advanced and customizable network slicing to address some of the highlighted challenges in migrating eHealth telemedicine services to 5G networks. An overview of the framework outlines the technical approaches in beyond the state-of-the-art network slicing. Subsequently, this paper emphasizes the design and prototyping of a media-centric eHealth use case, focusing on a set of innovative enablers toward achieving end-to-end QoS-aware network slicing capabilities, required by this demanding use case. Experimental results empirically validate the prototyped enablers and demonstrate the applicability of the proposed framework in such media-rich use cases.
