Tutorial: 5G Functional Splits, Orchestration and Network Management
|30/9/2019||14:00 – 16:00||Seminar room 7||Babak Jafarian||Parallel Wireless Inc|
While traditional mobile networks have been built relying on a “monolithic” hardware designed and manufactured by distinct vendor and distinct technology requirements, 5G and future mobile network solution are going to be multi-vendor, multi-technology and multi-layer. This seminar addresses the new concepts of network management and orchestration based on the introduction of SDN and NFV into operational networks. Also, considering heterogenous network deployment, provides an outlook for the new paradigm when deploying 5G networks.
Tutorial starts with reviews of the current trends in the overall design of 5G network architecture and will address how these architectures translate into new 5G RAN architecture requirements. The 5G protocol stack architecture will discussed in detail; differences with 4G, and what are the reasonable function splits in 5G RAN. Also, we will discuss the impact and challenges of network densifications in the future 5G deployments. Due to exponential increases in mobile data demands in recent years and deployment of 5G networks, soon network densification is considered as a key mechanism in the evolution of cellular network deployments. In the ultra-dense heterogeneous networks for 5G, the base stations are brought closer and closer to the users through dense deployments. However, the performance and capacity of the network does not increase monotonously with increasing number of base stations due to inter cell interference and backhaul/fronthaul limitation. We will address the challenges and solutions to tackle densification problems. The main topics are as follow:
