可选地，该目标参数包括用户业务中断时长、连接失败用户数以及备用虚拟资源的消耗数量中的至少一个，其中，该用户业务中断时长是指第一时间点与第二时间点之间的时长，该第一时间点为该更新后的VNF软件的运行时间点，该第二时间点为该更新后的VNF软件首次与用户终端建立承载连接的时间点。该连接失败用户数是指在该用户业务中断时长内与该更新后的VNF软件建立承载连接失败的用户终端数量。

图2A是根据另一示例性实施例示出的一种软件管理方法流程图，本实施例以该软件管理方法应用于EM中进行举例说明，该软件管理方法可以包括如下几个步骤：
步骤201：接收NFV编排器发送的VNF软件更新请求，该VNF软件更新请求携带更新计划、VNF软件标识、更新版本信息和该NFV编排器订阅的目标参数，该目标参数用于指示该VNF软件更新过程中目标运行指标的执行结果。
目前，在使用VNF软件的过程中，为了保证VNF软件的运行灵活性，需要对该VNF软件进行管理，例如，需要对该VNF软件进行更新或升级等之类的管理。在对VNF软件进行管理时，由于采用虚拟化技术的VNF实例化和更新的灵活性，要求对该VNF软件进行更新或升级的过程中即时保证VNF承载的用户业务正常运行，也即是，需要尽量避免对用户业务造成中断等之类的影响，为此，在对该VNF软件在线更新的之前，需要设置该VNF软件的更新计划，例如，该更新计划可以包括：在什么时间点或在哪个时间段内对该VNF软件进行更新等。
在实际应用过程中，该更新计划通常可以由NFV编排器来设置，由此可见，对于NFV编排器来说，希望能够获知更新后的VNF软件的运行信息，例如，需要获知用户业务中断时长、连接失败用户数以及备用虚拟资源的消耗数量等等，从而可以使得该NFV编排器在下一次对该VNF软件发起VNF软件更新请求时，可以针对该运行信息灵活调整对该VNF软件的更新计划，以便在更新过程中尽量减小对VNF所承载的用户业务的影响。
为此，在本发明实施例中，请参考图2B，NFV编排器向VNF管理器发送VNF软件更新请求时，在该VNF软件更新请求中携带更新计划、VNF软件标识、更新版本信息和该NFV编排器订阅的目标参数，VNF管理器接收到该VNF软件更新请求后，向该NFV编排器返回第一更新响应消息，且将该VNF软件更新请求转发至EM中，其中，该第一更新响应消息用于通知该NFV编排器已接收到该VNF软件更新请求，并进行进一步的处理。
其中，该目标参数包括用户业务中断时长、连接失败用户数以及备用虚拟资源的消耗数量中的至少一个，其中，该用户业务中断时长是指第一时间点与第二时间点之间的时长，该第一时间点为该更新后的VNF软件的运行时间点，该第二时间点为该更新后的VNF软件首次与用户终端建立承载连接的时间点。该连接失败用户数是指在该用户业务中断时长内与该更新后的VNF软件建立承载连接失败的用户终端数量。
其中，上述第一时间点为该更新后的VNF软件的运行时间点，也即是，第一时间点是指更新后的VNF软件在虚拟机中加载后上电运行的时间点，其中，该虚拟机中可以安装该更新后的VNF软件。且在一种可能的实现方式中，该安装有更新后的VNF软件的虚拟机可以与更新前的该VNF软件所在虚拟机由同一硬件资源承载，或者，在另一可能的实现方式中，该安装有更新后的VNF软件的虚拟机也可以与更新前的该VNF软件所在虚拟机由不同硬件资源承载，也就是说，更新后的VNF软件所在的虚拟机与更新前的VNF软件所在的虚拟机安装在不同的硬件资源中，在这种情况下，该不同硬件资源之间可以通过建立连接关系进行通信。
其中，上述用户终端一般是指暂态用户终端，具体地，在实际应用过程中，与VNF软件连接的用户终端通常可以包括两种：稳态用户终端和暂态用户终端。其中，该稳态用户终端是指已经附着在该VNF软件的控制面上，且与该VNF软件的用户面已经在稳定的传输数据的终端，而该暂态用户终端是指附着 在该VNF软件的控制面上，但尚未开始在VNF用户面传输数据的终端。因此，在VNF软件更新或升级的过程中，为了不影响稳态用户终端的正常运行，该稳态用户终端可以继续通过该VNF软件传输数据，但由于该暂态用户终端还产生数据，因此，该暂态用户终端可以重定向到该更新后的VNF软件，以验证该更新后的VNF软件是否能够在虚拟机上正常运行。也即是，在上述所提到的更新后的VNF软件首次与用户终端建立承载连接中的用户终端一般为暂态用户终端。
其中，上述备用虚拟资源的消耗数量是指在更新VNF软件的过程中，备用虚拟资源额外增加或减少的数量。其中，由于在该VNF软件更新的过程中，为了支撑VNF软件的更新，一般需要启动该VNF软件所在虚拟机的主备机制，因此，为了便于NFV编排器在后续的更新计划中确定虚拟机的备用资源，在对该VNF软件更新的过程中，需要确定该备用虚拟资源的消耗数量。
步骤202：基于该更新计划、该VNF软件标识和该更新版本信息，对该VNF软件进行更新。
其中，基于该更新计划、该VNF软件标识和该更新版本信息，对该VNF软件进行更新的具体实现过程可以包括：EM基于该VNF软件标识和该更新版本信息，确定该VNF软件对应的更新版本文件，该更新计划用于指示计划更新该VNF软件的时间点或时间段，EM在该更新计划所指示的时间点或时间段内，通过该更新版本文件对该VNF软件进行更新。
请继续参考图2B，EM接收到该VNF管理器转发的VNF软件更新请求后，向该VNF管理器返回第二更新响应消息，并管理该VNF软件标识对应的VNF软件进行更新，其中，该第二更新响应消息用于通知该NVF管理已接收到该VNF软件更新请求，并将对该VNF软件标识对应的VNF软件进行更新处理。
其中，该VNF软件标识可以用于唯一标识一个VNF软件。另外，EM基于该更新版本信息，可以唯一确定用于更新该VNF软件的更新版本文件，其中，该更新版本信息可以包括更新版本文件的厂家名称、更新版本文件的版本号等。
EM确定该更新版本文件后，即可通过该更新版本文件对该VNF软件进行更新，其中，通过更新版本文件对该VNF软件进行更新的具体实现方式可参见现有技术，本发明实施例对此不做限定。
EM对该VNF软件进行更新后，即可对该更新后的VNF的业务执行效果 进行监控，也即是，EM获取该更新后的VNF软件的运行信息，其具体实现过程可参见如下步骤204至步骤205。
步骤203：在该VNF软件的更新过程中，基于该目标参数，获取该目标参数对应的目标监控值。
其中，根据该目标参数所包括的内容不同，获取该目标参数对应的目标监控值可以包括如下任一种可能的实现方式：
第一种方式：如果该目标参数包括该用户业务中断时长，则向指定测试设备发送目标参数订阅请求，以使该指定测试设备获取并返回该用户业务中断时长对应的目标监控值，其中，该指定测试设备对该用户业务中断时长具有感知的作用，该目标参数订阅请求至少携带该用户业务中断时长，接收该指定测试设备返回的该用户业务中断时长对应的目标监控值。
其中，该指定测试设备可以是指网络中的测试系统或测试探针。请参考图2C，上述指定测试设备获取该用户业务中断时长对应的目标监控值的具体实现过程可以包括：该指定测试设备接收该目标参数订阅请求后，启动定时器开始计时，其中，该定时器可以为该指定测试设备自身携带的定时器，也可以为与该指定测试设备连接的外接定时器，并且，该指定测试设备模拟用户终端向安装有该更新后的VNF软件的虚拟机发起非接入层(Non Access Stratum，NAS)信令请求消息，例如，附着(Attach)请求、跟踪区更新(TrackingAreaUpdate，TAU)请求等，该虚拟机接收该NAS信令请求消息后，通过该更新后的VNF软件判断是否能够响应该NAS信令请求消息，如果经过该更新后的VNF软件内部测试验证确定无法响应该NAS信令请求消息，则向该指定测试设备发送响应失败消息。
在上述情况下，如果该指定测试设备接收到该响应失败消息，则将模拟用户终端，重新向安装有该更新后的VNF软件的虚拟机发送该NAS信令请求消息，直到该虚拟机返回响应成功消息，也即，该虚拟机能够通过该更新后的VNF软件响应该NAS信令请求消息，例如，该虚拟机能够通过该更新后的VNF软件实现用户终端的附着操作。当该指定测试设备接收到该响应成功消息时，控制该定时器终止计时，并将定时所得到的时长确定为该用户业务中断时长对应的目标监控值，该指定测试设备向该EM发送目标参数响应消息，该目标参数响应消息中携带该目标监控值。
其中，上述虚拟机通过该更新后的VNF软件内部测试判断是否能够响应 NAS信令请求消息的具体实现过程可以参见现有技术，本发明实施例对此不做详细描述。
第二种方式：如果该目标参数包括该连接失败用户数，则向安装有该更新后的VNF软件的指定VNF发送目标参数订阅请求，以使该指定VNF获取并返回该连接失败用户数对应的目标监控值，其中，该指定VNF对该连接失败用户数具有感知作用，该目标参数订阅请求还携带该连接失败用户数，接收该指定VNF返回的该连接失败用户数对应的目标监控值。
其中，在一种可能的实现方式中，EM向安装有更新后的VNF软件的指定VNF发起创建性能管理任务命令，该创建性能管理任务命令中携带该目标参数订阅请求，该安装有更新后的VNF软件的指定VNF接收该创建性能管理任务命令后，根据该目标参数订阅请求，创建性能管理任务，从而获取并返回该连接失败用户数对应的目标监控值。其中，创建性能管理任务的具体实现过程可以参见现有技术，这里不再赘述。另外，上述指定VNF获取该连接失败用户数对应的目标监控值的具体实现过程也可以参见现有技术，本发明实施例对此不做详细描述。
需要说明的是，在该实现方式中的连接失败用户数是指重定向安装有该更新后的VNF软件的虚拟机中的实际用户终端数量，而不是上述第一种实现方式中为测试更新后的VNF软件所模拟的用户终端数量。也即，在上述通过模拟用户终端测试该更新后的VNF软件可以执行网络功能后，上述暂态用户终端即可将新业务数据流重定向到安装有该更新后的VNF软件的虚拟机中，以验证该更新后的VNF软件是否可以在虚拟机上运行业务。
其中，这里需要介绍的是，暂态用户终端将新业务数据流重定向到安装有该更新后的VNF软件的虚拟机中的具体实现可以采用循序渐进的方式，也即是，暂态用户终端每次按照指定业务比例，将暂态用户终端的部分新业务数据流定向到该安装有更新后的VNF软件的虚拟机中运行，如果该虚拟机通过该更新后的VNF软件内部验证测试后确定业务运行效果较好，则再次按照该指定业务比例将暂态用户终端的新业务重定向到该安装有该更新后的VNF软件的虚拟机中运行，以此类推，直到将该暂态用户终端的所有新业务数据流均重定向到该安装有该更新后的VNF软件的虚拟机中。
之后，VNF管理器可以继续按照同样的方式，将上述稳态用户终端的业务数据流重定向到该安装有该更新后的VNF软件的虚拟机中，并在将稳态用户 终端的所有业务数据流均重定向到该安装有更新后的VNF软件的虚拟机中后，该VNF管理器将更新前的VNF软件在虚拟机中删除，同时释放该更新前的VNF软件所在的虚拟机的虚拟资源。其中，该指定业务比例可以由用户根据实际需求自定义设置，也可以由VNF管理器默认设置，本发明实施例对此不做限定。
第三种方式：如果该目标参数包括备用虚拟资源的消耗数量，则向虚拟化基础设施管理器VIM发送目标参数订阅请求，以使该VIM获取并返回该备用虚拟资源的消耗数量对应的监控值，其中，该VIM对该备用虚拟资源的消耗数量具有感知作用，该目标参数订阅请求还携带该备用虚拟资源的消耗数量，接收该VIM返回的该备用虚拟资源的消耗数量对应的监控值。
具体地，在该种实现方式中，EM向该VNF管理器发送目标参数订阅请求，该VNF管理器将该目标参数订阅请求转发至底层的VIM中，VIM接收到该目标参数订阅请求后，基于该目标参数订阅请求中携带目标参数，获取备用虚拟资源的消耗数量对应的目标监控值，并将所获取的目标监控值传递给EM。其中，VIM获取备用虚拟资源的消耗数量对应的目标监控值的具体实现过程可以参见现有技术，本发明实施例对此不做详细介绍。
步骤204：将该目标监控值发送至该NFV编排器，以使该NFV编排器基于该目标监控值确定更新后的VNF软件的运行信息。
请继续参考图2B，该EM获取到该目标监控值后，将所获取的目标监控值发送至该VNF管理器，并由该VNF管理器将该目标监控值发送至该NFV编排器，如此，即可使得该NFV编排器基于该目标监控值，确定更新后的VNF软件的运行信息，也即，该NFV编排器可以根据该运行信息，分析并设置下一次对该VNF软件进行更新的更新计划。
另外，需要说明的是，上述提供的软件管理方法还可以应用到非虚拟化网络环境下，对传统电信网元软件的管理中，例如，还可以应用到配有实际物理机壳的移动性管理实体(Mobility Management Entity，MME)软件的更新过程中，其具体实现方式与本发明实施例提供的软件管理方式类似，这里不再赘述。
在本发明实施例中，在对VNF软件进行更新的过程中，NFV编排器通过在VNF软件更新请求中至少携带用于订阅反映该VNF软件更新过程中目标运行指标执行结果的目标参数，使得用于管理该VNF软件更新过程的EM接收该VNF软件更新请求后，在对该VNF软件进行更新的过程中，获取该目标参 数对应的目标监控值，之后，EM将所获取的目标监控值发送至该NFV编排器，从而使得该NFV编排器可以基于该目标监控值，确定更新后的VNF软件的运行信息，也即，确定更新后的VNF软件运行用户业务的执行效果。
