The evolution of 5G mobile radio and its complex interaction with fixed access network infrastructures poses new challenges and opportunities. In this article, a software-defined converged fixed-mobile 5G architecture is introduced using carrier-grade Ethernet as a transport platform. An active remote node (ARN) is used to connect end-users. Powered at a radio base station, the ARN aggregates the traffic of fixed and mobile radio users. Transport capacity is reduced due to statistical multiplexing, and scalability is achieved by a modular design. The ARN enables software-defined networking (SDN) via the open-networks-as-a-service (Open NaaS) control and management plane. Adopting the Open Access model, this architecture offers both, multi-technology and multi-operator features. Next generation fronthaul, resource sharing, synchronization, low latency can all be established as services to build an advanced 5G infrastructure.
