Various arrangements for managing cellular network slicing are detailed. A cellular network management system may obtain performance data from cellular network components of a cellular network over time. The cellular network management system may analyze the performance data from the plurality of cellular network components to create a cellular network model indicative of performance of discrete portions of the cellular network over time. A service request may be received from an external entity that defines quality of service (QoS) parameters. A cellular network access conditions package may be created that defines conditions under which the external entity is eligible to utilize the cellular network. Cellular network components may then be configured to permit access to the cellular network by user equipment (UE) of the external entity and data services may be provided to the UE.
