Distributed ledger control over wireless network slices
A wireless communication network executes a smart contract in distributed ledger circuitry and responsively instantiates a wireless network slice for a wireless communication device. The wireless communication network transfers user data for the wireless communication device over the wireless network slice and responsively transfers slice usage data for the wireless communication device to the distributed ledger circuitry. The wireless communication network executes the smart contract in the distributed ledger circuitry and responsively stores the slice usage data for the wireless communication device in the distributed ledger circuitry.
1. A method of operating a wireless communication network to serve a wireless communication device over a wireless network slice using one or more distributed ledger nodes, the method comprising:
the one or more distributed ledger nodes transferring a slice request for the wireless communication device to a network orchestrator;
the network orchestrator instantiating the wireless network slice for the wireless communication device responsive to the slice request;
the wireless network slice transferring user data for the wireless communication device and responsively transferring slice usage data for the wireless communication device to the one or more distributed ledger nodes;
the one or more distributed ledger nodes storing the slice usage data for the wireless communication device;
the one or more distributed ledger nodes transferring a termination request to the network orchestrator; and
the network orchestrator terminating the wireless network slice for the wireless communication device responsive to the termination request.
2. The method of claim 1 further comprising:
the one or more distributed ledger nodes transferring a new slice request for the wireless communication device to the network orchestrator;
the network orchestrator instantiating a new wireless network slice for the wireless communication device responsive to the new slice request;
the new wireless network slice transferring new user data for the wireless communication device and responsively transferring new slice usage data for the wireless communication device to the one or more distributed ledger nodes; and
the one or more distributed ledger nodes storing the new slice usage data for the wireless communication device.
3. The method of claim 2 further comprising the one or more distributed ledger nodes storing linking data that correlates the slice usage data, the new slice usage data, and the wireless communication device.
4. The method of claim 2 wherein the one or more distributed ledger nodes comprise smart contracts that have a same digital certificate.
5. The method of claim 1 further comprising the one or more distributed ledger nodes generating a slice usage amount for the wireless communication device based on the slice usage data.
6. The method of claim 1 wherein the wireless network slice comprises at least one of a User Plane Function (UPF), an Application Server (AS), and an Internet Protocol Multimedia Subsystem (IMS).
7. The method of claim 1 wherein the wireless network slice transferring the user data for the wireless communication device comprises the wireless network slice transferring the user data for the wireless communication device in response to receiving a slice request from the wireless communication device.
8. A wireless communication network to serve a wireless communication device over a wireless network slice using one or more distributed ledger nodes, the wireless communication network comprising:
the one or more distributed ledger nodes configured to transfer a slice request for the wireless communication device to a network orchestrator;
the network orchestrator configured to instantiate the wireless network slice for the wireless communication device responsive to the slice request;
the wireless network slice configured to transfer user data for the wireless communication device and responsively transfer slice usage data for the wireless communication device to the one or more distributed ledger nodes;
the one or more distributed ledger nodes further configured to store the slice usage data for the wireless communication device;
the one or more distributed ledger nodes further configured to transfer a termination request to the network orchestrator; and
the network orchestrator further configured to terminate the wireless network slice for the wireless communication device responsive to the termination request.
9. The wireless communication network of claim 8 wherein:

the network orchestrator is further configured to instantiate a new wireless network slice for the wireless communication device responsive to the new slice request;
the new wireless network slice is further configured to transfer new user data for the wireless communication device and responsively transfer new slice usage data for the wireless communication device to the one or more distributed ledger nodes; and
the one or more distributed ledger nodes are further configured to store the new slice usage data for the wireless communication device.
10. The wireless communication network of claim 9 wherein the one or more distributed ledger nodes are further configured to store linking data that correlates the slice usage data, the new slice usage data, and the wireless communication device.
11. The wireless communication network of claim 9 wherein the one or more distributed ledger nodes are configured to execute smart contracts that have a same digital certificate.
12. The wireless communication network of claim 8 wherein the one or more distributed ledger nodes are further configured to generate a slice usage amount for the wireless communication device based on the slice usage data.
