面向5G ToB业务的高可用性网络

High Availability Network for 5G ToB Services

5G面向商业(to Business,ToB)的业务是面向不同行业的5G网络部署及应用。由于业务应用的对象不同,ToB网络在网络组网结构及业务可靠性要求等方面与传统的面向消费者(to Costumer,ToC)的网络相比具有显著的差异。ToB业务不仅关注网络的低时延、大上行等特性,而且对网络的可用性也有更高的要求。通过分析业务高可用性的相关指标及模型,给出了不同业务等级协定(Service Level Agreement,SLA)要求下的网络可用性提升技术与规划方案,并通过具体案例进行说明。所提方案能够满足5G ToB业务的高可用性需求,从而支撑企业高效生产。

5G ToB services are deployed and applied on 5G networks in different industries.Due to different objects,5G ToB services are significantly different from traditional ToC networks in terms of networking structure and service reliability requirements.ToB services not only focus on network features such as low latency and large uplink,but also have higher requirements on network availability.Through analyzing indicators and models related to high availability of services,this paper provides network availability improvement technologies and planning solutions for different SLA(Service Level Agreement)requirements,and illustrates through specific cases.The proposed solution can meet the high availability of 5G ToB services,thereby supporting efficient production of enterprises.
