5G网络共建共享模式

随着5G 的大规模部署，5G网络设备单价高、建设投资大，设备功耗大、运营成本高的问题日益突出，在高质量建设的同时，提升 5G 网络的运行效率和效益，共建共享成为运营商探索网络建设和运营的新模式。从网络架构、频率使用等方面，对5G网络共建共享进行了深入分析，提出了独立载波、共享载波、异网漫游3种网络共建共享技术方案，针对各方案进行了优缺点对比和适用场景分析，并指出当前面临的挑战，总结如何选择合理的部署方式推进共建共享。

5G network co-construction and sharing mode

With the large-scale commercial deployment of 5G,the problems of high unit price of 5G network equipment,large construction investment,high power consumption of equipment and high operation cost are increasingly prominent.In addition to high-quality construction,improving the operation efficiency and efficiency of 5G network,and building and sharing become a new mode of network construction and operation explored by operators.5G network co-construction and sharing from the aspects of network architecture and frequency use were analyzed,and three kinds of network co-construction and sharing technology schemes were put forward:independent carrier,shared carrier and different network roaming.The advantages and disadvantages of each scheme were compared,and the applicable scenarios were analyzed,the current challenges were pointed out.It was summarized how to choose a reasonable deployment mode to promote co construction and sharing.
