随着5G愿景和概念的清晰,网络切片已逐渐成为解决多种使用场景的潜在方案;但在多个网络实例共存的情况下,网络的管理和用户对网络的附着将面临诸多问题.基于5G的发展趋势与其关键技术,提出一种以网络切片管理器为核心的管理方案.借助网络功能虚拟化技术实现网络切片创建与修改的完全自动化;在多个网络实例共存的情况下,网络切片选择模块辅助用户实现网络附着.该体系将网络分为了基础资源、网络实例和业务三层;并形成开放的平台,使得每一层都将可以单独作为服务进行出售、租赁和管理.这将改变现有电信领域的商业模式,并为其运维带来更多的灵活性.%As the vision and concept of the 5G is becoming more and more transparent,network slicing has gradually become a potential solution to various scenarios.But in the case of coexistence of multiple network instances,network management and users' attachment to the network encounter many problems.Based on the development trend of 5 G and its key technology,a management scheme with network slice manager as the core is proposed.Network functionality virtualisation is used to realize the complete automation of the creation and modification of network slices.As for the coexistence of multiple network instances,the network slice selection module can assists the users to attach to network instances.This scheme divides the network into three layers,which are respectively infrastructure layer,network instance layer and services instance layer.Meanwhile it makes the telecommunications network an open platform,which allows each layer in it to be sold,tenanted and managed as a service.This changes the existing business model of the telecommunications field and brings more flexibility for its operation and maintenance.
