System and method for global slice and/or dnn registry

A system comprising:

• a memory that stores computer-executable instructions;
• and
• a processor that executes the computer-executable instructions and causes the system to:
• access a global slice and Data Network Name (DNN) registry for user devices, wherein each slice/DNN is managed by the global slice and DNN registry and each slice/DNN is used to identify and route traffic to a specific network service;
• register, in the global slice and DNN registry, slice/DNN ranges that can be accessed by other participating telecommunication networks of the multiple participating telecommunication networks;
• create unified slice/DNN IDs with associated slice/DNN ranges for each corresponding user device, wherein the unified slice/DNN IDs are accessible by the multiple participating telecommunication networks;
• use the unified slice/DNN IDs to enable routing to equivalent slice/DNN functionality for the network service in each of the multiple participating telecommunication networks;
• and
• create a slice/DNN overlay network that provides user devices with an equivalent network service in the multiple participating telecommunication networks.

A system comprising:

• a memory that stores computer-executable instructions;
• and
• a processor that executes the computer-executable instructions and causes the processor to:
• register, in a global slice registry, slice ranges that can be accessed by participating telecommunication networks on a global slice registry for user devices, wherein slice ranges include a plurality of slices, and wherein each slice is managed by the global slice registry and each slice is used to identify and route traffic to a specific network service;
• receive a connection request from a roaming customer to connect to a participating telecommunication network;
• receive a destination request from the roaming customer to be routed to a specific designation using a network slice ID;
• access the global slice registry and use the network slice ID to enable routing to equivalent slice functionality on the participating telecommunication network;
• receive orchestration data that enables the participating telecommunication network to instantiate a roaming customer's equivalent slice functionality on the participating telecommunication network;
• and
• instantiate the roaming customer's equivalent slice functionality on the participating telecommunication network.
