业务实例层负责具体井下业务创建及生命周期维护； 络切片实例（Network Slice Instance，NSI）层通过将设备抽象为独立的NS，生成可定制、逻辑独立、业务隔离的NSI，以供不同需求的业务订购者定制使用；资源层负责对NSI层提供计算、存储、转发、无线接入等功能。

通过动态修改NS模板内各 络主要性能指标参数，实现对NSI生命周期的管理，满足了业务对NS按需定制、灵活使用的需求；通过对NSI隔离属性进行动态配置和管理，以及对NSI隔离要求进行全局性操作，实现NS隔离，达到NS所承载业务之间互不干扰的目的。根据时延敏感类、带宽敏感类和连接数量敏感类井下业务对NS划分，给出了典型井下业务下NS工作状态，可满足矿山通信 络对差异化垂直业务的灵活配置需求。

【摘要】针对目前矿山通信 络多源异构的系统架构具有资源共享率低、维护升级困难、垂直业务部署配置不够灵活高效等问题，将 络切片（NS）技术应用于矿山通信 络中。构建了基于NS的矿山通信 络架构，NS在矿山通信 络中的部署分为业务实例层、 络切片实例（NSI）层、资源层，分别与矿山通信 络的应用层、传输层、感知层对应：业务实例层负责具体井下业务创建及生命周期维护；NSI层通过将设备抽象为独立的NS，生成可定制、逻辑独立、业务隔离的NSI，以供不同需求的业务订购者定制使用；资源层负责对NSI层提供计算、存储、转发、无线接入等功能。通过动态修改NS模板内各 络主要性能指标参数，实现对NSI生命周期的管理，满足了业务对NS按需定制、灵活使用的需求；通过对NSI隔离属性进行动态配置和管理，以及对NSI隔离要求进行全局性操作，实现NS隔离，达到NS所承载业务之间互不干扰的目的。根据时延敏感类、带宽敏感类和连接数量敏感类井下业务对NS划分，给出了典型井下业务下NS工作状态，可满足矿山通信 络对差异化垂直业务的灵活配置需求。

【Abstract】Aiming at problems of low resource sharing efficiency, difficult maintenance and upgrade, and inflexible and inefficient vertical service deployment and configuration caused by multi-source heterogeneous structure of mine communication network, network slice(NS) technology was applied to mine communication network. Mine communication network architecture based on NS was constructed. Deployment of NS in mine communication network is divided into service instance layer, network slice instance(NSI) layer and resource layer, which respectively correspond to application layer, transmission layer and perception layer in mine communication network. The service instance layer is responsible for underground service creation and life cycle maintenance. By abstracting device into independent NS, the NSI layer generates customizable, logically independent and service isolated NSI for customized use by service subscribers with different requirements. The resource layer is responsible for providing computing, storage, forwarding, wireless access and other functions to the NSI layer. By dynamically modifying key performance indicators parameters of each network in NS template, management of NSI life cycle is realized, which meets service requirements of customization and flexible use of NS. Through dynamic configuration and management of NSI isolation attributes and global operation of NSI isolation requirements, NS isolation is realized to achieve purpose of non-interference among services carried by NS. NS was divided according to latency sensitive, bandwidth sensitive and connection quantity sensitive underground services, and NS working state under typical underground services was given, which could meet flexible configuration requirements of mine communication network for differentiated vertical services.
