4th edition of Mobility Support in Slice-based Network Control for Heterogeneous Environments

9th November 2021, Heraklion, Greece

Held in conjunction with the VII IEEE Conference on Network Function Virtualization and Software Defined Networks


Network slicing has been a key capability brought forward by the novel 5G mobile architecture. Supported by the integration of novel mechanisms and tools, such as Software Defined Networking, Network Function Virtualization and RAN enhancements, this capability has triggered a broad spectrum of technological and technical work. This work was able to produce not only important findings for better service provisioning in mobile environments, but also manifested an unprecedented degree of interest from vertical players who see this as a definitive game-changer for evolving their operations to new levels. However, the full-fledged integration of such industries placed new stringent requirements over the network service provisioning, which generated new challenges (not only over the wellknown concept of the mobile network itself, but also on its reliance on the new tools, such as virtualization and softwarization). This has become evident in first assessments and validations from deployments in real and experimental scenarios, fuelled by international research initiatives involving telcos, system providers, vendors and many other participants of the value chain. With Release 17 underway and the planning for Release 18 starting, concepts such as 5G-Advanced, Beyond-5G and 6G have started to target key novel concepts for further evolution. Where does mobile-enabled slicing stand? Is it supported in the projected roadmap? Are the different vertical sectors, along with their disparate evolution cycles, enabled to take advantage of this capability? Or is mobile-enabled slicing a topic that paved the way in 5G for further research into the upcoming new generations? Over its previous iterations, MOBISLICE has dedicated itself to bringing together the different visions of academia, industry and standardization on solutions that integrate different building blocks from different players into innovative and ground-breaking new scenarios, aiming towards an holistic approach for the enablement, assessment and deployment of Network Slicing perspectives in X-mobility environments (where X can mean devices, resources, services or even slices themselves). In this edition, MOBISLICE IV will look into the future, starting from the lessons learnt by the different players implementing these solutions in the latest commercial equipment, and address the research space on mobile network slicing for the future. What have been the key contributions with the current generation and what is able to be deployed? What are the shortcomings evidenced and which enhancements should the underlying fabric of the network/computing continuum have to optimally support mobile network slicing?.

Topics of Interest

The MOBISLICE workshop focuses, but is not limited to, the following topics targeting slicing:

Vertical use cases and architectures validation:
  • Slices in constrained environments (IoT, Edge, etc.);
  • Factories of the future use cases including manufacturing automation and process automation;
  • Automotive service and ITS scenarios;
  • Telco Operator and enterprise-based environments;
  • Smart-X slice mobility;
  • Reliability and security;
  • Experimental and real trials and their impact in vertical performance.
Network, computation and other enablers:
  • Main operations and API;
  • Inter- and intra-slice mobility;
  • Lifecycle management and impact;
  • Heterogeneous access convergence or abstraction;
  • High availability and reliability techniques;
  • Experimental and real trials.
Standardization efforts and activities:
  • Status and progresses in 3GPP/ETSI/IETF/5GAA and other SDOs and vertical associations such as 5G-ACIA/5GAA;
  • Proposals and standardization direction for advanced slicing;
  • SDN/NFV initiatives;
  • Slice-enhanced Networking and telecommunication protocols.
Beyond-5G and 6G slicing:
  • Disruptive architectures;

Dr. Riccardo Trivisonno, Head of Network Architecture, Huawei Technologies

Short bio: Riccardo Trivisonno (IEEE M’08, SM’19) is currently serving as Head of Network Architecture for the Advanced Wireless Technologies Lab at Huawei Technologies, Munich Research Center. His research and standardization group develops and delivers technologies to standardization bodies in the areas of Network Architecture, Core Network and Network Management. The group focuses on B5G and 6G systems, and on 3GPP/ETSI standards. He joined Huawei Technologies in 2011. He holds a PhD and an MSc in Telecommunications Engineering from University of Bologna (achieved in 2005 and 2000, respectively).

The Evolution of Network Slicing - from 5G to 5G Advanced, and towards 6G

Network Slicing has been one of the key enablers for the application of communication systems to Vertical use cases, and its potentials are far from being fully exploited. The keynote revisits the Network Slicing journey, starting from its conceptual definition, touching upon its introduction in the first 5G 3GPP Release 15 specifications, and then describing the enhancements of the following Releases 16 and 17. The keynote continues with an outlook of further evolution of Network Slicing in 5G-Advanced systems, and concludes with insights on how the concept may influence the definition of systems beyond 5G.
