NEXT GENERATION TERRESTRIAL BROADCASTING PLATFORM ALIGNED INTERNET AND TOWARDS EMERGING 5G NETWORK ARCHITECTURES

摘要

A Next Generation Broadcast Platform (NGBP) is disclosed that utilizes 5G software-defined networking (SDN) and network function virtualization (NFV) technologies. The NGBP is designed to enable a new paradigm for broadcasters, wherein the model of fixed wireless spectrum access granted only to the licensees of the spectrum is replaced by a flexible model in which licensed spectrum is pooled together and allocated dynamically to broadcast licensees as well as outside tenants. The NGBP, implemented using SDN/NFV technology, includes a broadcast market exchange (BMX) entity that allocates the spectrum between tenants based on service level agreements (SLAs) with those users. The NGBP includes an internet protocol (IP) core and a broadcast centralized radio access network (BC-RAN) which apply the major network functions to broadcaster content in accordance with the determinations of the BMX. The SDN/NFV implementation offers several distinct advantages over NGBP implemented with dedicated network hardware.
