基于C-RAN的移动城域网5G承载方案探讨

Discussion on 5G Bearer Solution of C-RAN Based Mobile Metropolitan Area Network

C-RAN集中化组网方式是5G无线接入网络建设中的一种可行性方式,其在实现网络运营成本有效控制与降低方面具有较为显著的作用和效果,但同时也对传输承载网络提出了更高的要求。本文将结合移动城域传输网络建设现状,提出一种基于C-RAN的移动城域网5G承载方案,并针对该方案中的前传承载设计以及其传输承载组网方案进行研究,以供参考。

C-RAN centralized networking is a feasible method in the construction of 5G wireless access networks.It has a significant role and effect in achieving effective control and reduction of network operating costs,but it also affects transmission bearers.The network has put forward higher requirements.This paper will propose a 5G bearer solution based on C-RAN based on the current status of the construction of the mobile metropolitan area transmission network,and study the design of the fronthaul and backhaul bearers and its transmission bearer network scheme in this solution for reference.
