Description

软件升级方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种软件升级方法及装置。
背景技术
在相关技术中，在无线通讯系统的管理领域，网络管理系统(Network Management System，简称为NMS)与网元管理系统(Element Management System，简称为EMS)之间的接口称为北向接口(itf-N)。EMS主要完成国际电信联盟(International Telecommunication Union，简称为ITU)电信管理网络(Telecommunications Management Network，简称为TMN)中的网元管理层(Element Management Layer，简称为EML)功能，即完成一个或多个移动通信设备的管理功能，通常不同设备供应商之间的EMS无法通用。NMS主要完成ITU TMN中的网络管理层(Network Management Layer，简称为NML)功能，负责一个被管网络内所有网元的管理。对于被管网络(称为子网)内存在多个设备供应商的情况，可以通过各自的EMS管理达到管理整个子网的目的。
相关技术为了提高通讯网络的灵活性，降低管理成本，由运营商发起提出了网络功能虚拟化(Network Functions Virtualization，简称为NFV)概念，在使用NFV技术的情况下，原来的物理网元设备由虚拟化网络功能(Virtualized Network Function，简称为VNF)代替，使得网络功能与具体硬件解耦，VNF与底层的网络功能虚拟化基础架构(Network Functions Virtualization Infrastructure，简称为NFVI)隔离。对于VNF的管理，通过EMS对VNF实例进行传统的维护管理功能，而VNF的生命周期管理功能则通过VNF管理器(Virtualized Network Function Manager，简称为VNFM)完成。底层的虚拟基础架构由虚拟基础架构管理器(Virtualized Infrastructure Manage，简称为VIM)进行管理。而具体的网络业务，则一般通过一个或多个VNF实例来完成。对网络业务的管理，则通过网络功能虚拟化编排器(Network Functions Virtualization Orchestrator，简称为NFVO)来进行。实现网络功能虚拟化后，从应用层面来看，要建立一个网络业务实例时，需要先生成网络业务需要的VNF的实例，再由一个或多个VNF实例组成一个网络业务实例，通过网络业务实例来提供网络业务。在实行虚拟化之后，VNF实例其实就是运行在虚拟基础架构之上的虚拟操作系统软件和相应的应用层软件，这些软件在其生命周期中需要不断地进行升级。
针对相关技术中，VNF软件升级方案不完善的问题，目前还没有有效地解决方案。
