The present document provides the possible scenarios for:
  • the interconnection of an Next Generation Corporate Network (NGCN) with a Next Generation Network (NGN); and
  • the support of NGCN capabilities within an NGN, either towards a User Equipment (UE) or to an NGCN.
Unless otherwise specified by reference to other documents, all requirements relating to architecture and functional requirements are contained within the present document.
