This clicing capability allows utilities toe avoid over- provisioning thee network for worst- case direcles. They can accupase or lease precisely the service quality they need, reducing operationation they need, costs while meeting regulatory requiments. Standards bodies like 3GPP and the ETSI have definite network slicing management interfaces that integrate with utility operations support systems (OSS).
