  As the 5G standards mature and awareness of the capabilities of the
technology increases, industry verticals are becoming more eager to test new
services and develop them to the level of maturity required for market
adoption. Network slicing, i.e. multiple virtual networks running on a common
infrastructure, is considered a key mechanism to serve the multitude of tenants
(e.g. vertical industries) targeted by forthcoming fifth generation (5G)
systems, in a flexible and cost-efficient manner. It is predicted that one of
the most popular models for customers will be the Network Slice as a Service
(NSaaS) model. This model allows a Network Service Customer to order and
configure a Network Slice and offered it as a service. This work presents
Openlice a Service based, opens-ource OSS for delivering NSaaS following
emerging standards from SDOs. We strongly believe that such open source
solutions make it easier for organizations to enable complex scenarios
especially in the are of Non-Public Networks.
