  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.
