Description

资源调整方法、通信节点、通信装置、通信系统和服务器
相关申请
本申请要求于2021年12月10日申请的、申请号为202111509139.5的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及无线通信技术领域，特别涉及一种资源调整方法、通信节点、通信装置、通信系统和服务器。
背景技术
随着软件定义网络(SoftwareDefinedNetwork，简称SDN)或网络功能虚拟化(Network Functions Virtualization，简称NFV)技术推进移动通信网络向云化网络演进，移动通信网络的运维和运营都需要进行重大的变革。尤其是5G技术的出现，以切片为基本单位进行运维和运营的模式对传统的运维和运营方式造成了重大的影响，对于错误、配置、计帐、性能和安全的管理职能(Fault，Configuration，Accounting，Performance and Security，简称FCAPS)的传统运维模式逐步转向以切片为单位的云化运维方式。在云化运维模式下，最大的变化就是资源能够满足业务需要,因此云化网络下的资源运维显得尤为重要，一方面资源需要支撑切片，以切片为单位去支撑业务，另一方面要能够动态调整切片资源，使得切片能够实时适度的去满足业务，在不造成资源浪费的情况下使得资源利用率最优，就要求云化网络运维的重点在于动态资源调整的智能决策。
当前3GPP协议已经制定了一套端到端切片的标准管理规范，网络切片Network Slice是指一组经过编排和配置的网络功能和资源的集合，这个集合构成可以提供特定网络能力和网络特性的完整逻辑网络。这里的网络特性包括超低延时、增强带宽等。网络切片通常跨多个技术域，包括接入网、传输网、与核心网。网络切片子网Network Slice Subnet是网络切片的子集，网络切片中的接入网、传输网或者核心网可以单独构成一个网络切片子网。按照3GPP协议的描述，网络切片管理功能(Network Slice Management Function，简称NSMF)负责端到端切片实例的管理与编排，而网络切片子网管理功能(Network Subnet Slice Management Function，简称NSSMF)负责网络切片子网实例的管理与编排，按照技术域NSSMF可以划分为无线NSSMF、核心网NSSMF和承载NSSMF。NSMF/NSSMF切片管理系统架构以及端到端切片部署流程如图1所示，用户发起切片创建请求，NSMF从切片实例创建请求中携带的服务等级协议(Service-Level Agreement，简称SLA)推导分解出对应的核心网(Core Network，简称CN)、承载网(Bearing Network，简称BN)、无线接入网(Radio Access Network，简称RAN)等各切片子网相关SLA，下发给各NSSMF，发起切片子网实例的创建；NSSMF收到切片子网实例的创建请求后，根据切片子网SLA，例如无线接入技术、带宽、端到端延迟、吞吐量等等，创建切片子网实例，生成网络服务资源模型和业务配置，下发给网络功能虚拟化编排器(Network Functions Virtualization Orchestrator，简称NFVO)或网元管理模块(Element Management，简称EM)，完成网络切片/网络功能虚拟化VNF的实例化，给网络功能虚拟化VNF下发业务配置，激活切片子网实例，最终部署成功一个端到端网络切片实例。
然而，按照3GPP协议的描述，网络切片是自组织的，是基于对管理数据进行分析的，应该实现SLA闭环管理的；但是，自组织功能如何引入，管理数据分析哪些数据，以及如何实现闭环，3GPP协议并没有在架构、流程和接口层面给出描述，因而不利于后续通信厂商实现，从而导致通信厂商无法自动优化调整切片资源，造成网络资源的利用率低。
