Abstract

The service-based approach and network slicing capability in 5G brings new technical and business opportunities for the telecom ecosystem. Industry verticals that have previously relied on multiple dedicated physical networks for use case specific services, can now be provisioned with multiple virtual network slices running over the same physical network infrastructure. Hence, the telecom ecosystem is set to expand with new use cases and stakeholders, and the techno-economic aspects of network slice provisioning need to be studied. The thesis studies the 5G standardization, the technical, economic, and managerial aspects of network slicing, and the various emerging ecosystems and stakeholders. The thesis also studies different industry verticals as case studies, to gain a comprehensive understanding for developing future scenarios, strategies, business models, and cost models for network slice provisioning.Several techno-economic methods are utilized in the research. Value network analysis is used to study the different business actors and their technical and business relationships. Scenario planning is used to analyze alternative future scenarios for 5G deployments. Data is collected from university campus and smart factory case studies. New management strategies and business models are developed, and their feasibility is studied for different verticals. A novel cost model for the virtualization infrastructure for network slice provisioning is developed and evaluated for the smart factory case study. The thesis contributes to the development of 5G network slicing ecosystem with manifold results, with a few highlighted here. The future scenarios help understand the uncertainties and possible opportunities for different stakeholders. The developed business models can be employed for different service offerings and value creation. The interaction between different network domains is studied as part of the management strategies including the possible interworking between the local and wide area networks. Further, the developed cost model for virtualization infrastructure is applied to a real smart factory as the slice customer, accompanied with a sensitivity analysis for extreme scenarios.
