Network Slicing Management Technique for Local 5G Micro-Operator Deployments

Local 5G networks are expected to emerge to serve different vertical sectors specific requirements. These networks can be deployed by traditional mobile network operators or entrant local operators. With a large number of verticals with different service requirements, while considering the network deployment cost in a single local area, it will not be economically feasible to deploy separate networks for each vertical. Thus, locally deployed 5G networks (aka micro operator networks) that can serve multiple verticals with multiple tenants in a location have gained increasing attention. Network slicing will enable a 5G micro-operator network to efficiently serve the multiple verticals and their tenants with different network requirements. This paper addresses how network slicing management functions can be used to implement, orchestrate and manage network slicing in different deployments of a local 5G micro-operator including the serving of closed, open and mixed customer groups. The paper proposes a descriptive technique by which different network slicing management functionalities defined by 3GPP can be used in coordination to create, orchestrate and manage network slicing for different deployment scenarios of a micro-operator. This is based on the network slice instance configuration type that can exist for each scenario. A network slice formation sequence is developed for the closed micro operator network to illustrate the tasks of the management functions. The results indicate that network slicing management plays a key role in designing local 5G networks that can serve different customer groups in the verticals.

Network Slice Instantiation for 5G Micro-Operator Deployment Scenario

The concept of network slicing is considered as a key part in the development of 5G. Network slicing is the means to logically isolate network capabilities in order to make each slice responsible for specific network requirement. In the same light, the micro-operator concept has emerged for local deployment of 5G for vertical specific service delivery. Even though microoperator networks are expected to be deployed using 5G, most research on network slicing has been directed towards the description on the traditional (MNO) networks with little emphasis on slicing in local 5G networks deployed by different stakeholders. In order to achieve slicing in a micro-operator network, it is of vital importance to understand the different deployment scenarios that can exist and how slicing can be realized for each of these deployments. In this paper, the microoperator networks described include closed, open and mixed network, and for each of these network, different deployment scenarios are established. The paper further proposes approaches for the configuration of Network Slice Instances (NSIs) using the Network Slice Subnet Instances (NSSIs) and other Network Functions (NFs) in a micro-operator network while considering the different deployments. The results highlight the possible deployment scenarios that can be established in a micro-operator network and how network slicing can be efficiently realized for the various local deployments.

Micro-Operator driven Local 5G Network Architecture for Industrial Internet

In addition to the high degree of flexibility and customization required by different vertical sectors, 5G calls for a network architecture that ensures ultra-responsive and ultra-reliable communication links. The novel concept called micro-operator (uO) enables a versatile set of stakeholders to operate local 5G networks within their premises with a guaranteed quality and reliability to complement mobile network operators' (MNOs) offerings. In this paper, we propose a descriptive architecture for emerging 5G uOs which provides user specific and location specific services in a spatially confined environment. The architecture is discussed in terms of network functions and the operational units which entail the core and radio access networks in a smart factory environment which supports industry 4.0 standards. Moreover, in order to realize the conceptual design, we provide simulation results for the latency measurements of the proposed uO architecture with respect to an augmented reality use case in industrial internet. Thereby we discuss the benefits of having uO driven local 5G networks for specialized user requirements, rather than continuing with the conventional approach where only MNOs can deploy cellular networks.
