Abstract

In order to analyze the mobile communication in the next few years in the evolution from 4G to 5G on transmission especially IPRAN network, this paper is based on the changes of characteristic of the wireless network and capacity, connection and time delay sensitivity features such as a sharp rise. It analyzes the development demand for transmission network, based on the 5G demand, puts forward target transmission network architecture, carries a plan of prequel and postpass, and calculates the bandwidth within the metropolitan area transmission network, discusses the metro IPRAN for 5G network evolution direction of the core layer, convergence layer and accesess layer and technical characteristics.
