背景技术
第五代(5th-generation,5G)移动通信系统(简称5G系统)采用最为先进的移动通信技术,它能够为移动用户提供超级容量的带宽速率和更安全的通信,满足各行各业广泛变化的业务需求。5G系统采用网络切片技术将一个物理网络切割成多个虚拟的端到端的网络,每个虚拟网络可称为一个网络切片(network slice,NS),每个网络切片是逻辑独立的,每个网络切片由一个独立的网络功能或功能组合实例构成,如:每个网络切片可以包括至少一个网络组件,每个网络组件可以通过其上暴露的接口对外提供网络服务,以满足不同租户的业务需求和服务。
目前,管理人员可以根据自身需求对网络组件对外提供的网络服务进行管理,如:管理人员可以向运营商发送管理请求,运营商根据该管理请求查看网络组件支持的管理服务,将网络组件支持的管理服务反馈给管理人员以实现网络服务的管理。但是,这种传统的管理网络服务的方法需要人工协商管理,耗时,效率低下。
