摘　　要：介绍了C-RAN架构的基本原理、特点及演进方向,然后分析了高负荷场景网络所面临的挑战。提出了一种基于C-RAN架构的高负荷场景网络规划解决方案。在C-RAN架构下,通过解耦网络覆盖层与容量层,就近部署容量层发射点来下沉承载业务,并利用Massive MIMO的多流与复用特性优势,提高了高负荷场景的网络容量与网络性能;同时,研究网络业务的潮汐效应,利用C-RAN架构开发载波自动快速调度算法,进一步提高载波资源利用效率与业务承载能力,最终实现用户感知质量的有效提升。By introducing the basic principles and characteristics of the C-RAN architecture as well as its evolution,and analyzing the challenges of networks in high-load scenarios,a network planning solution of high-load scenarios based on the C-RAN architecture is proposed.In this planning solution,the network is decoupled as overlay layer and capacity layer.The capacity layer cells can be deployed to business hotspots as near as possible,and utilize the Massive MIMO feature of multi-streams and multiplexing to improve the network capacity and performance in high-load scenarios.Furthermore,the tidal effect of traffic model is researched to develop an algorithm,by which carriers can be fast scheduled automatically in high-load scenarios area.This algorithm,based on the C-RAN architecture,can further improve utilization efficiency and bearing capacity of the network,finally effectively improve user perception quality.
