C-RAN技术在网络优化中的应用

Application of C-RAN Technology in Network Optimization

随着LTE用户数和流量的不断增长,网络容量需求不断增加。然而,不断增加基站会导致网络的CAPEX/OPEX逐年增高,无线接入网络的机房、无线设备、传输设备、后备电源以及空调等设备冗余浪费和能源消耗问题变得日益严重。因此,必须考虑新的无线接入网络构架以适应新的环境,并满足营收和未来移动互联网业务同步发展的要求。C-RAN通过减少基站机房数量和能耗,采用协作化、虚拟化技术,实现资源协作,提高频谱效率,达到了低成本、高带宽和灵活度的运营方式。

With the increasing number of LTE users and traffic,the demand for network capacity is increasing,and the increasing of the base station will result in the increase of the network CAPEX/OPEX year by year.The redundancy and energy consumption of wireless access network,wireless equipment,transmission equipment,backup power,air conditioning and other equipment have become more and more serious.We must consider the new wireless access network architecture to adapt to the new environment and meet the requirements of the synchronous development of revenueand future mobile Internet services. By reducing the number of the base stations and reducing the energy consumption,the cooperative and virtualized technology is adopted to achieve the cooperation of resources and the efficiency of the spectrum to achieve low cost and high bandwidth. C-RAN And the operating mode of the spirit activity.
