Next Generation Mobile Core Resource Orchestration: Comprehensive Survey, Challenges and Perspectives

摘要: Re-architecting mobile network functions and central office is one of the hottest topics software defined networking (SDN) function virtualization (NFV). It known as Next generation (NGMN). The main benefit re-architecting to bring cloud advantages operator networks. On other hand, while openness most wanted characteristics NGMN, many open source implementations have been introduced accelerate realizing NGMN such resource allocation management orchestration which considered hardest problems in SDN, NFV, virtualization. To that end, this article has comprehensively reviewed core architecture, evolutions order investigate relay operators on components, especially developing countries, build their future infrastructure for 4G/5G (fourth/fifth generations) access Furthermore, shows a large number infrastructure’ components needs integrate them together, challenging task. Moreover, addresses integration framework challenges based continuous development (DevOps) model. outcomes work encourage involve contribute efforts well test scenarios.
