Abstract
The main requirements of 5G are emerging through the efforts of diverse groups such as 4G America in United States, IMT-2020 (5G) promotion group in China and the 5G Private Public Partnership (5G PPP) in Europe. The 5G requirements will tremendously increase the network complexity which requires auto-integration and self-management capabilities that are well beyond today's self-organising network features. Additionally, ultra-reliable communications put very stringent latency and reliability requirements on the architecture.
