1. A 5G OpenRAN controller, comprising:
a 5th generation core (5GC) and evolved packet core (EPC) virtualization stack interface for virtualizing core resources having distinct performance characteristics;
a radio virtualization stack interface for virtualizing radio resources having distinct performance characteristics; and
a slice selection function executing on the 5G OpenRAN controller,
wherein the 5G OpenRAN controller virtualizes existing cells using the radio virtualization stack interface into a pool of virtualized radio access network (RAN) resources that can be allocated dynamically; and
wherein the 5G OpenRAN controller virtualizes multiple cores using the 5GC and EPC virtualization stack interface into a pool of virtualized core resources for multi-technology RANs and presents them as standard interfaces to at least one of the 5GC and the evolved packet core, and
wherein the slice selection function connects a virtualized radio resource and a virtualized core resource to create a network slice,
thereby providing any-G network slicing.
