Architecture Vision for the 5G Era: Cognitive and Cloud Network Evolution

Requirements and use cases for the 5G era are demanding in key dimensions such as throughput, latency, scalability and automation. From these, an end-to-end architectural vision has been developed in a holistic way and including novel architectural concepts including 5G access domain and 5G era horizontal layers in conjunction with cloud, software defined and cognitive networks transformation. End-to-end architecture for the 5G era is decomposed in a systematic manner, key attributes and characteristics of the associated architectural domains are described.
