基于多载频配置方案的高铁负荷评估与优化研究

Capacity assessment and optimization research of high-speed railway based on multiple frequency configuration scheme

高铁是4G/5G建设的窗口场景,高端用户密集且近年来持续增长。随着5G建设,网络结构更为复杂。覆盖场景的多样性、各厂家设备能力的差异、已有公网组网结构及翻频退频等后期优化调整导致高铁专网存在丰富的载频配置方案。本文针对高铁专网的差异性及传统“一刀切”容量评估方法的不足,提出了一种基于多载频配置方案的高铁负荷评估方法,该方法可有效评估高铁专网不同场景下的负荷状态,为及时进行容量保障、提升客户感知、促进流量增长提供优化思路,应用效果良好。

High-speed railway is one of the window scenes of 4G/5G wireless network,with a high density of VIP users and continuous growth in recent years.With the construction of 5G,the wireless network structure is more and more complex.Due to the diversity of coverage scenarios,the difference of equipment capacity of each manufacturer,the existing public network networking structure and the operation of frequency reversal,there are abundant frequency configuration schemes in the high-speed railway private network.Aiming at the differences of high-speed railway private network and problems of the traditional"one size fits all"capacity assessment method,this paper proposes a capacity assessment scheme for high-speed railway private network based on multiple frequency configuration scheme,which could effectively evaluate the load variation of high-speed railway network in different scenarios.Through application,this method is proved to be an efficient way to guarantee capacity,improve customer perception and promote traffic growth.
