Abstract

Abstract:

At present, China is in the wave of new infrastructure construction.It had become an industry consensus to accelerate the construction of new information infrastructure resources such as 5G and computing resources, and then it was integrated with advanced technologies such as AI and big data to promote the high-quality development of China’s digital economy.As the main force of the digital economy, the banking industry urgently need to vigorously develop financial technology and explore intelligent transformation.Based on the industry pain points of the banking industry, combined with the urgent needs of customers in the banking industry, five business scenarios were sorted out including AI passenger flow insight and 5G+XR immersive marketing, and the key issues of planning and networking in the banking industry based on the above five business scenarios were summarized.It will help to construct of the industry’s 5G private network and successfully realize the digital and intelligent transformation of China’s banks.

Key words: new infrastructure construction, banking industry, 5G private network, intelligent transformation

覆盖场景	基站类型	设备选型	适用场景	技术应用
银行室外覆盖	宏基站	64T64R	银行视频类业务区域	大规模MIMO巨大的阵列增益提升单用户的信噪比，降低用户间干扰，提升网络性能指标
		32T32R	银行其他区域	大规模MIMO巨大的阵列增益提升单用户的信噪比，降低用户间干扰，提升网络性能指标
银行室内覆盖	室分	4T4R分布式皮基站	营业厅、大型会议室、展厅等	分布式皮基站可提供最好的用户上下行速率体验，适用于对上下行速率有较高要求的业务场景
		2T2R分布式皮基站	办公楼、食堂等	分布式皮基站可提供最好的用户上下行速率体验，适用于对上下行速率有较高要求的业务场景

RB资源预留	资源说明
专用资源	仅切片用户组内用户可用，不能被其他切片用户组抢占
优先资源	有资源剩余时，普通用户可用，可实现一定程度上的绝对优先
共享资源	Rel-16版本新增，所有用户基于QoS公平使用
注：3GPP Rel-16即国际标准组织3GPP于7月3日发布的5G第一个演进版本标准，主要研究内容为eMBB功能增强、毫米波增强、URLLC增强功能等，进一步增强5G网络性能和竞争力，为用户带来更优质的业务体验。

保障方案	保障效果	安全隔离性	建议应用场景
RB资源预留	保障确定性要求高，不受背景 GBR、资源预留业务影响；对时延可靠性有极致要求，例如5G+XR沉浸式营销业务，网络需求为20 ms的空口时延、99.99%的可靠性	高	5G+XR沉浸式营销
注：5G智慧银行行业在B2（公网专用）场景下，toB、toC客户共基站资源，且toB与toC运维团队、配置流程等相对独立。RB资源预留使用时需对基站PRB资源进行事前勘察（GBR、普通toC客户基线速率占用资源以外），若资源不足，则需通知客户无法订购产品。

专用节点类型	资源配置建议	适用场景说明
通用型	vCPU内存比1:4	适用于高网络包收发场景
计算型	vCPU内存比1:2	适用于数据分析等计算密集型场景
大数据型	vCPU内存比1:4（大硬盘）	适用于海量数据存储和计算场景
