Scope, complexity ,and scale of even a single 5G network are massively larger than in today's networks.The main challenge is automation on all levels of the 5G ecosystem.without it, the network simply will not work; neither for the anticipated scale nor for the desired functional complexity.
Fundamentally, automation is realized by a largely self-governed network bound to varying business goals: ifs configuration, its services, how they are provided, and how it is managed. A governance model, ideally realized by policies, defines how these goals are implemented and monitored. Those policies can be low-level configuration parameters, mid -level strategies or high-level intents and goals. Using a mix of these -policies implies translation between: top-down for realization and bottom-up for action / benefit and validation purposes.
Networks and models must address multiple, diverse constituencies. Human intervention should be kept to a minimum（ oversight ）. Management means monitoring and repair; not control . Classic self capabilities are the benefits
