1. A computer implemented method for hierarchical network slicing, comprising:
obtaining a set of single network slice selection assistance information (S-NSSAI);
for each S-NSSAI of the sets:
determining a Tenant Slice-Group based, at least in part, on a slice differentiator (SD) part of the S-NSSAI; and
implementing Unified Access Control (UAC) based, at least in part, on the SD part of the S-NSSAI; and
processing the set of S-NSSAI in accordance with a hierarchy of network slicing including a plurality of Tenant Slice-Groups each including one or more network slices, wherein at least one function of each network slice under a Tenant Slice-Group in the hierarchy is inherited from a root corresponding to the Tenant Slice-Group.
