具体实施方式
随着云计算技术的不断发展，云平台在多个领域得到广泛应用。电信行业在此基础上提出了网络功能虚拟化(Network Functions Virtualization，简称NFV)技术。
为了提高通信网络的灵活性，降低网络成本、提升网络稳定性，利用基于NFV技术的虚拟网络功能(Virtualized Network Function，简称VNF)代替电信运营商网络中的物理网元，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NFVI)隔离。
VNF被称作虚拟网元，其在功能上与物理网元相同，只是在实现上，虚拟网元为虚拟设备，物理网元为物理设备。但是，在应用过程中，物理网元容易受到资源的限制，而虚拟网元可以根据需求配置最大的资源配置，然后根据负荷的大小，自动进行弹性伸缩，避免资源浪费或不足。
以下结合附图以及实施例，对本发明进行进一步详细说明。应当理解， 此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。
实施例一
本实施例提供了一种虚拟网元的升级方法。如图1所示，为根据本发明第一实施例的虚拟网元的升级方法的流程图。
步骤S110，创建最新版本的虚拟机。
虚拟机是指：通过软件模拟的具有完整硬件系统功能的、运行在一个完全隔离环境中的完整的计算机系统。
虚拟网元包括OMM虚拟机、OMP虚拟机以及其他的业务处理虚拟机。对虚拟网元进行升级，也即是对该虚拟网元中的虚拟机分别进行升级。
OMM(Operation Maintenance Module，操作维护模块)虚拟机在后台运行，用于监控数字程控交换机的工作情况。
OMP(Operation Management Processor，操作维护处理模块)虚拟机在前台运行，用于管理业务处理虚拟机以及处理前后台通讯。
在虚拟网元升级之前，需要预设一个升级时段，该升级时段为预先申请的、专门用于升级虚拟网元的时段，以便在该升级时段之内执行影响虚拟网元业务正常运行的升级操作。该升级时段例如是：每天凌晨0:00～4:00。升级时段的起始时刻被称作升级时刻，本实施例可以在预设的升级时刻到来之前，预先创建最新版本的OMP虚拟机和OMM虚拟机，以便使用最新版本的OMP虚拟机和OMM虚拟机，替换虚拟网元中低版本的OMP虚拟机和OMM虚拟机。
步骤S120，使用最新版本的虚拟机，无缝替换虚拟网元中相应的虚拟机，以实现对该虚拟网元的升级。
因为升级时段有限，为了避免升级时段较短，造成在升级时段内无法升级虚拟网元中的全部虚拟机，进而引起的升级不成功的问题，本实施例根据不同类型的虚拟机对虚拟网元业务运营产生的影响、以及虚拟机升级 的特点，在升级时段之内或之外，分别升级每种类型的虚拟机。
由于升级OMM虚拟机对虚拟网元的业务运营无影响，所以，可以在预设的升级时刻到来之前，使用最新版本的OMM虚拟机，替换虚拟网元中的OMM虚拟机。进一步地，可以是在线升级OMM虚拟机，也可以是使用预先创建的最新版本的OMM虚拟机，替换虚拟网元中低版本的OMM虚拟机。
由于升级OMP虚拟机的时间较长、且可能会对虚拟网元的业务运营产生影响，所以，在预设的升级时刻到来之时，使用所述最新版本的OMP虚拟机，无缝替换虚拟网元中的OMP虚拟机，以实现对OMP虚拟机的替换。
由于除OMM虚拟机、OMP虚拟机之外的其他业务处理虚拟机是在OMP虚拟机的控制下完成升级，且升级过程不影响虚拟网元业务的正常运营，因此，在OMP虚拟机升级完成之后，可以在升级时段之内或之后，由OMP虚拟机控制这些业务处理虚拟机升级。
在升级间段来临之前，先升级OMM虚拟机；在升级间段内，处理OMP虚拟机的升级，使用最新版本的OMP虚拟机替换虚拟网元中低版本的OMP虚拟机，以及通过OMP虚拟机升级其他的业务处理虚拟机。这样可以保证在正式升级的时间段内OMP虚拟机以及业务处理模块可以升级完成，进一步保证虚拟网元可以升级完成，并且可以提高虚拟网元的升级效率。
实施例二
本实施例的虚拟网元可以不采用冗余设计，也即是说，该虚拟网元中的虚拟机只有主虚拟机、无备虚拟机。
如果虚拟机无冗余，则可以预先创建最新版本的虚拟机；在升级低版本的主虚拟机时，将该新版本的虚拟机作为备虚拟机接入；在新版本的备虚拟机和低版本的主虚拟机之间进行数据同步；将新版本的备虚拟机切换为主虚拟机，将低版本的主虚拟机切换为备虚拟机并删除。这样，在升级 虚拟网元的过程中，虚拟网元不会停止运行，不会中断业务运营。
本实施例的虚拟网元也可以采用冗余设计，来提高虚拟网元的安全性，也即是说，虚拟网元中的虚拟机的类型包括主虚拟机和备虚拟机。进一步地，OMM虚拟机、OMP虚拟机和其余虚拟机都包含主虚拟机和备虚拟机。一般而言，在虚拟网元中设置一对主、备OMM虚拟机，一对主、备OMP虚拟机，以及主、备比例为1：n的业务处理虚拟机，其中，n≥1。
如果在虚拟网元中包括主OMP虚拟机和备OMP虚拟机，则在创建最新版本的虚拟机时，仅创建最新版本的第一OMP虚拟机、或者创建最新版本的第一OMP虚拟机和第二OMP虚拟机。使用第一OMP虚拟机替换虚拟网元中的主OMP虚拟机，并在线升级所述虚拟网元中的备OMP虚拟机；或者，使用第一OMP虚拟机替换虚拟网元中的主OMP虚拟机，使用第二OMP虚拟机替换虚拟网元中的备OMP虚拟机。这样，可以实现OMP虚拟机在时间上的无缝替换，保证在升级OMP虚拟机的过程中，虚拟网元也可以正常运行，业务运营不受影响。
OMM虚拟机的替换方式可以参考OMP虚拟机的替换方式。本实施例优选地，先完成OMM虚拟机的替换，再创建新版本的OMP虚拟机。OMM虚拟机也可以采用在线升级的方式完成升级，如果采用在线升级的方式，则先在线升级备OMM虚拟机，再升级主OMM虚拟机。
实施例三
本实施例进一步地描述使用所述第一OMP虚拟机替换虚拟网元中的主OMP虚拟机，并在线升级所述虚拟网元中的备OMP虚拟机。如图2所示，为根据本发明第二实施例的虚拟网元的升级方法的流程图。在本实施例中，虚拟网元中正在运行的OMP虚拟机包括：第三OMP虚拟机和第四OMP虚拟机。其中，第三OMP虚拟机作为主OMP虚拟机，第四OMP虚拟机作为备OMP虚拟机。
步骤S210，创建最新版本的第一OMP虚拟机。
步骤1，获得虚拟网元的新配置数据文件。
该新配置数据文件是由新版本的OMM虚拟机生成的。
升级后台的OMM虚拟机可能会使虚拟网元的前台的配置数据发生改变，所以，在创建第一OMP虚拟机之前，先升级OMM虚拟机；在OMM虚拟机升级完成之后，由新版本的OMM虚拟机为前台重新生成虚拟网元的配置数据文件。该配置数据文件包含为新增加的功能而增加的配置数据。OMP虚拟机升级后的新功能需要使用到该新增加的配置数据。
步骤2，为第一OMP虚拟机申请虚机资源。
虚机资源包括：第一OMP虚拟机所需的硬件资源和/或软件资源。例如：申请的虚拟资源包括：中央处理器(Central Processing Unit，简称CPU)、内存、硬盘、网卡等。
步骤3，获取新版本的OMP镜像文件。
该新版本的OMP镜像文件包括：新版本的OMP操作系统的镜像文件和OMP新版本文件。OMP新版本文件是包含新功能的可执行文件。
同样的，OMM虚拟机也会存在新版本的OMM操作系统的镜像文件。步骤4，在申请的虚机资源的基础上，根据虚拟网元的新配置数据文件和OMP镜像文件，创建第一OMP虚拟机。
在虚拟机(OMM虚拟机和OMP虚拟机)创建完成后，生成一个虚拟机对应的唯一性编码。
步骤S220，停止运行第四OMP虚拟机，并将第一OMP虚拟机作为备OMP虚拟机接入虚拟网元。
步骤1，获取第一OMP虚拟机、第三OMP虚拟机和第四OMP虚拟机的虚机参数的唯一性编码。
步骤2，在升级时刻到来时，下电第四OMP虚拟机。
在对虚拟机进行操作和控制时，根据虚拟机的唯一性编码来识别该虚拟机。进一步地，根据第四OMP虚拟机的唯一性编码，来识别该第四OMP虚拟机，实现对该OMP虚拟机的操作和控制。
步骤3，上电第一OMP虚拟机，并将第一OMP虚拟机设置为备OMP虚拟机。
步骤S230，在第一OMP虚拟机和第三OMP虚拟机之间进行数据同步。
数据同步的作用在于，将第三OMP虚拟机作为主OMP虚拟机运行期间的数据，例如动态数据，同步到第一OMP虚拟机中，使第一OMP虚拟机包括主OMP虚拟机中的数据。
步骤S240，将第一OMP虚拟机切换为主OMP虚拟机，将第三OMP虚拟机切换为备OMP虚拟机。
该步骤用于实现使用第一OMP虚拟机替换虚拟网元中的主OMP虚拟机。
在第一OMP虚拟机中包括主OMP虚拟机中的数据时，第一OMP虚拟机就具备了作为主OMP虚拟机的条件，因此，可以将第一OMP虚拟机切换为主OMP虚拟机，将第三OMP虚拟机切换为备OMP虚拟机。
步骤S250，第三OMP虚拟机在线升级完成之后，删除第四OMP虚拟机。
因为，作为主OMP虚拟机的第一OMP虚拟机已经是最新版本，所以，只需升级作为备OMP虚拟机的第三OMP虚拟机即可。
在第三OMP虚拟机升级之前，可以对第一OMP虚拟机进行业务验证；若验证通过，则升级第三OMP虚拟机，删除第四OMP虚拟机；若验证未通过，则执行回退处理。
业务验证是指：基于第一OMP虚拟机，验证虚拟网元的功能是否正常；若正常，则表示验证通过；若不正常，出现错误，则表示验证不通过。
回退处理是指：将第一OMP虚拟机下电，重新将第三OMP虚拟机设置为主OMP虚拟机、将第四OMP虚拟机设置为备OMP虚拟机。也即是说，回退处理是将虚拟网元回退至原来的版本，暂停升级。
在第三OMP虚拟机升级完成之后，虚拟网元中的主OMP虚拟机和备OMP虚拟机都为新版本，停止运行的第四OMP虚拟机则可以被删除，以便释放第四OMP虚拟机占用的虚机资源。
如果在线升级第三OMP虚拟机之时，第一OMP虚拟机出现故障，则可以重新上电第四OMP虚拟机，将第四OMP虚拟机作为主OMP虚拟机。
本实施例在升级时段内无缝替换主OMP虚拟机，仅申请一个OMP虚拟机的虚机资源即可，可以缓解资源紧张的问题，并且升级较为简便，并且可以降低在升级时段内升级所有虚拟机造成的升级失败的风险。
实施例四
本实施例进一步地描述使用所述第一OMP虚拟机替换虚拟网元中的主OMP虚拟机，使用所述第二OMP虚拟机替换虚拟网元中的备OMP虚拟机。如图3所示，为根据本发明第三实施例的虚拟网元的升级方法的流程图。在本实施例中，虚拟网元中正在运行的OMP虚拟机包括：第三OMP虚拟机和第四OMP虚拟机。其中，第三OMP虚拟机作为主OMP虚拟机，第四OMP虚拟机作为备OMP虚拟机。
步骤S310，分别创建最新版本的第一OMP虚拟机和第二虚拟机。
创建第一OMP虚拟机和第二OMP虚拟机的过程都可以参考步骤S210中的描述。创建第二OMP虚拟机仅需将步骤S210中的第一OMP虚拟机替换为第二OMP虚拟机即可。
步骤S320，停止运行第四OMP虚拟机，并将第一OMP虚拟机作为备OMP虚拟机接入虚拟网元。
将作为备OMP虚拟机的第四OMP虚拟机下电，同时将第一OMP虚 拟机作为备OMP虚拟机接入虚拟网元。
步骤S330，在第一OMP虚拟机和第三OMP虚拟机之间进行数据同步。
在数据同步的过程中，第三OMP虚拟机将其作为主OMP虚拟机期间的数据同步给第一OMP虚拟机。
步骤S340，将第一OMP虚拟机切换为主OMP虚拟机，将第三OMP虚拟机切换为备OMP虚拟机。
该步骤用于实现使用第一OMP虚拟机替换虚拟网元中的主OMP虚拟机。
步骤S350，停止运行第三OMP虚拟机，并将第二OMP虚拟机作为备OMP虚拟机接入虚拟网元。
将作为备OMP虚拟机的第三OMP虚拟机下电，同时将第二OMP虚拟机作为备OMP虚拟机接入虚拟网元。
步骤S360，在第二OMP虚拟机和第一OMP虚拟机之间进行数据同步。
当第二OMP虚拟机作为备OMP虚拟机接入虚拟网元之后，第二OMP虚拟机需要获得主OMP虚拟机中的数据，这时，可以通过在第二OMP虚拟机和第一OMP虚拟机之间进行数据同步，使第二OMP虚拟机获得主OMP虚拟机中的数据。进一步地，第一OMP虚拟机中的数据是第一OMP虚拟机和第三OMP虚拟机进行数据同步时，从第三OMP虚拟机中获得的。
步骤S370，删除已经停止运行的第三OMP虚拟机和第四OMP虚拟机。
在删除第三OMP虚拟机和第四OMP虚拟机之前，可以对第一OMP虚拟机和第二OMP虚拟机进行业务验证；若验证通过，则删除第三OMP虚拟机和第四OMP虚拟机；若验证未通过，则执行回退处理，重新将第三OMP虚拟机作为主OMP虚拟机，将第四OMP虚拟机作为备OMP虚拟机。
本实施例预先创建主OMP虚拟机和备OMP虚拟机，并在时间上实现无缝替换虚拟网元中低版本的主、备OMP虚拟机，这样可以避免在网元升 级过程对通信业务的不良影响，即在网元升级过程中，网元的业务不受影响，而且，本实施例避免了在线升级时间较长的问题，缩短了网元升级的时间，提高了网元升级的效率，降低了网元升级引起的风险。
实施例五
本实施例提供一种虚拟网元VNF升级系统。该系统包括：VNF管理器(VNF Manager(s)，简称VNFM)、虚拟基础架构管理器(Virtualised Infrastructure Manager(s)，简称VIM)、NFV编排器(Network Function Virtualization Orchestrator，简称NFVO)、版本中心、虚拟网元。
VNF管理器管理VNF的生命周期，也即是管理虚拟网络功能。
VIM管理器管理VNF底层的虚拟基础架构，提供虚拟资源。
NFVO编排器负责管理网络规划，实现对虚拟资源布局，使一个或多个VNF完成一个具体的业务。
版本中心负责存储每个版本的操作系统的文件。
版本中心可以设置在存储设备中；NFVO、VNFM、VNF和VIM可以运行在虚拟环境中；VNF可以运行在VIM中；NFVO可以提供用户界面，操作员通过用户界面管理网络规划和资源布局。
本实施例基于上述系统，更进一步地描述使用第一OMP虚拟机替换虚拟网元中的主OMP虚拟机，并在线升级虚拟网元中的备OMP虚拟机。如图4所示，为根据本发明第四实施例的虚拟网元的升级方法的时序图。为了使本实施例便于理解，在本实施例的时序图中添加了操作员项。
步骤1，操作员通过FTP将新版本镜像文件和新版本文件上传到版本中心。
该新版本镜像文件包括：新版本的OMM镜像文件和新版本的OMP镜像文件。新版本的OMM镜像文件包括：OMM操作系统镜像文化和OMM 新版本文件。新版本的OMP镜像文件包括：OMP操作系统镜像文件和OMP新版本文件。
本实施例的新版本的OMM镜像文件和新版本的OMP镜像文件都配置成不可拆分文件，也即是说，新版本的OMM镜像文件中的OMM操作系统镜像文化和OMM新版本文件不可拆分，新版本的OMP镜像文件中的OMP操作系统镜像文件和OMP新版本文件也不可拆分。因此，为了方便OMM虚拟机(以下简称OMM)和OMP虚拟机(以下简称OMP)升级，本实施例单独上传OMM新版本文件和OMP新版本文件。步骤2，操作员向NFVO下达版本在板开始的指令。
版本在板是指将新版本镜像文件上传到VIM的过程。
步骤3，NFVO将新版本镜像文件和新版本文件从版本中心下载到本地。
步骤4，NFVO验证新版本镜像文件和新版本文件。
如果验证通过，则将新版本镜像文件上传到VIM，并提示操作员上载完成；如果验证未通过，则提示操作员重新上载。例如：NFVO验证新版本镜像文件的完整性、安全性等。
步骤5，将验证通过的新版本镜像文件上传到VIM。
步骤6，操作员启动升级准备工作。
步骤7，NFVO向VNFM发送OMM升级消息。在该OMM升级消息中包含新版本文件在版本中心中的存储地址。
步骤8，VNFM从版本中心下载新版本文件。也即是说，VNFM从版本中心下载OMM新版本文件和OMP新版本文件。
步骤9，VNFM通过VNFM和VNF之间的接口，向VNF中的OMM发送升级命令。
OMM新版本文件被存储在VNFM中，则在升级命令携带OMM新版 本文件在VNFM中的存储路径。
步骤10，OMM从VNFM下载OMM新版本文件，开始在线升级；并在OMM虚拟机升级完成之后，通知VNFM。
如果VNF包括OMM主机和OMM备机，则先升级OMM备机，将该升级后的OMM备机切换为主机，将原OMM主机切换为备机，再对切换后的OMM备机进行升级。
步骤11，VNFM向OMM发送配置数据文件生成命令。
步骤12，OMM生成配置数据文件，并将配置数据文件发送给VNFM。
步骤13，VNFM收到配置数据文件后，向VIM申请虚机资源。VNFM在向VIM申请虚机资源，即是控制VIM生成OMP虚拟机的过程。
步骤14，VNFM控制VIM使用新版本的OMP镜像文件和配置数据文件，创建OMP虚拟机，并将携带有OMP唯一性编码的创建完成消息返回给VNFM。
至此，升级前准备工作完成。
步骤15，在升级时刻到来时，操作员向NFVO发出OMP升级请求。
步骤16，NFVO向VNFM发起OMP升级请求。
步骤17，VNFM控制新建的OMP作为备机上电，控制原OMP备机下电。
VNFM可以向原OMP主机发送备机下电命令，原OMP主机同意原OMP备机指示原OMP备机下电。
步骤18，VNFM向原OMP主机和新建OMP备机发送切换命令，控制原OMP主机和新建OMP备机进行同步数据，并分别进行主备切换。即将原OMP主机切换成备机，将新建OMP备机切换成主机。
步骤19，从VNFM下载OMP新版本文件，在线升级被切换为备机的原OMP主机。
OMP新版本文件在VNFM中的存储路径可以在与VNFM的交互过程中获得。从VNFM下载OMP新版本文件，根据该OMP新版本文件，对被切换为备机的原OMP主机进行在线升级。
步骤20，被切换为备机的原OMP主机在线升级完成以及同步数据之后，被切换为主机的新建OMP通知VNFM，OMP升级完成。
OMP升级完成即是OMP主机和OMP备机都升级完成。
步骤21，VNFM通知NFVO，OMP升级完成。
OMP升级完成的结果可以在NFVO用户界面中被操作员看到。
在升级完成之后，可以将下电的备OMP主机删除，释放其占用的资源。
与图4的处理过程不同的是，基于上述系统，使用所述第一OMP虚拟机替换虚拟网元中的主OMP虚拟机，使用所述第二OMP虚拟机替换虚拟网元中的备OMP虚拟机，VNFM需要使用新版本的OMP镜像文件和配置数据文件，创建两个OMP虚拟机，即第一OMP虚拟机和第二OMP虚拟机，VNFM需要控制作为备机的第四OMP虚拟机下电，将第一OMP虚拟机作为备机接入；在第一OMP虚拟机和作为主机的第三OMP虚拟机之间进行数据同步；将第一OMP虚拟机切换为主机，将第三OMP虚拟机切换为备机；将切换为备机的第三OMP虚拟机下电，并将第二OMP虚拟机作为备机接入；在第二OMP虚拟机和第一OMP虚拟机之间进行数据同步；删除第三OMP虚拟机和第四OMP虚拟机。
