Abstract
A wireless network control system facilitates a handover of User Equipment (UE) from a source network slice to a target network slice. The source slice delivers an internet-access service to the UE using a Quality-of-Service level and access restrictions. The UE detects a handover trigger and exchanges handover signaling with the source network slice. A hardware-trust controller verifies a hardware identification code embedded in the UE responsive to the handover signaling. A distributed ledger generates a slice template to implement the QoS and access restrictions for the UE in the target network slice in response to the handover signaling and the hardware-trust verification. The signaling circuitry transfers the slice template to the target slice. The target slice delivers internet-access service to the UE using the QoS and the restrictions in response to the slice template.
