具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。
请参阅图1，图1为一种网络切片管理系统结构示意图，如图1所示，该网络切片管理系统包括：通信业务管理功能(Communication Service Management Function，简称CSMF)实体，网络切片管理功能(Network Slice Management Function，简称NSMF)以及网络切片子网管理功能(Network Slice Subnet Management Function，简称NSSMF)。在实际应用中，上述NSSMF可以设置为多个。
CSMF可以负责将运营商和/或第三方客户的通信服务需求转化为对网络(切片)的需求，并通过和NSMF之间的接口向NSMF发送对网络切片的需求(如创建、终结、修改网络切片实例请求等)，从NSMF获取网络切片的管理数据(如性能、故障数据等)，生成运行于网络切片实例之上的通信业务的管理数据，接收运营商和/或第三方客户对网络切片管理数据和/或通信业务的管理数据的订阅需求等。
NSMF可以负责接收CSMF发送的网络切片需求，对网络切片实例的生命周期、性能、故障等进行管理(以下将生命周期、性能、故障管理简称管理)，编排网络切片实例的组成，分解网络切片实例的需求为各网络切片子网实例和/或网络功能的需求，向各NSSMF发送网络切片子网实例管理请求。
NSSMF可以负责接收NSMF发送的网络切片子网需求，对网络切片子网实例进行管理，编排子排网络切片实例的组成，分解网络切片子网实例的需求为各网络功能和/或嵌套网络切片子网实例的需求，可能向其他NSSMF发送嵌套网络切片子网实例管理请求。
网络切片实例(Network slice instance，简称NSI)：是一个真实运行的逻辑网络，能满足一定网络特性或服务需求。一个网络切片实例可能提供一种或多种服务。网络切片实例可以由网管系统创建，一个网管系统可能创建多个网络切片实例并同时对它们进行管理，包括在网络切片实例运行过程中的性能监视和故障管理等。当多个网络切片实例共存时，网络切片实例之间可能共享部分网络资源和网络功能。网络切片实例可能从网络切片模板创建，也可能不从网络切片模板创建。一个完整的网络切片实例是能够提供完整的端到端的网络服务的，而组成网络切片实例的可以是网络切片子网实例(Network Slice Subnet Instance,NSSI)和/或网络功能。网络功能可以包括物理网络功能和/或虚拟网络功能。以下统称物理网络功能和/或虚拟网络功能为网络功能。
网络切片子网实例(Network Slice SubnetInstance，简称NSSI)：网络切片子网实例可以不需要提供端到端的完整的网络服务，网络切片子网实例可以是网络切片实例中同一个设备商的网络功能组成集合，也可能是按域划分的网络功能的集合，例如核心网网络切片子网实例、接入网网络切片子网实例，或由部署位置等其他方式组成集合。网络切片子网实例可能被多个网络切片实例共享。提出网络切片子网实例，可以方便网管系统管理。一个网络切片实例可能由若干网络切片子网实例组成，每个网络切片子网实例由若干网络功能和/或若干网络切片子网实例组成；一个网络切片实例可能由若干网络切片子网实例和没有被划分为网络切片子网实例的网络功能组成；一个网络切片实例也可能仅由若干网络功能组成。
网络功能(Network function，简称NF)：是网络中的一种处理功能，定义了功能性的行为和接口，网络功能可以通过专用硬件实现，也可以通过在专用硬件上运行软件实现，也可以在通用的硬件平台上以虚拟功能的形式实现。因此，从实现的角度，可以将网络功能分为物理网络功能和虚拟网络功能。而从使用的角度，网络功能可以分为专属网络功能和共享网络功能，具体地，对于多个(子)网络切片实例而言，可以独立地使用不同的网络功能，这种网络功能称为专属网络功能，也可以共享同一个网络功能，这种网络功能称为共享网络功能。
下面通过一些实际的网络切片管理流程来说明网络切片管理的流程。
参阅图2a，图2a为一种网络切片实例创建流程图，如图2a所示，该创建流程中的指令可以为：创建NSI指令、调整NSI指令、创建NSSI指令、调整NSSI指令、配置NSSI指令。该网络切片实例创建包括如下步骤：
步骤S201a、CSMF接收通信服务请求，该请求中包含业务需求，例如该通信服务所需覆盖的地理范围、对网络的隔离需求、安全需求、应用需求、网络的关键性能指标(KPI) 等。
步骤S202a、CSMF将收到的通信服务需求转化为网络切片相关的需求。该需求中包括了为所述通信服务提供服务的网络切片实例是否可和其他通信服务共享。
步骤S203a、CSMF将所述网络切片相关需求发送至NSMF，请求NSMF分配(创建)一个网络切片实例(NSI)。
步骤S204a、NSMF分析该请求是否能够被满足，当请求对应的需求(例如设备、网络等等资源)不能被满足时，NSMF拒绝该请求，并向CSMF发送拒绝反馈。当该请求对应的需求可以被满足时，执行下述步骤：
步骤S205a、NSMF判断是否可重用现有NSI来满足该需求，如果可以重用现有NSI来满足该需求，则NSMF编排对现有NSI的调整需求，并执行网络切片实例调整相关流程；如果不可重用现有NSI，则NSMF创建新NSI以满足该需求。
步骤S206a、NSMF编排NSI并将NSI的需求分解为各网络切片子网实例(NSSI)的需求。该需求中包括了所需NSSI是否可以和其他NSI共享。如NSMF确定所需NSSI不可以和其他NSI共享，执行步骤S207a、步骤208a以及步骤S211a，如NSMF确定所需NSSI可以和其他NSI共享，执行步骤S209a、步骤S210a以及步骤S211a。
步骤S207a、创建新的NSSI，NSMF将新的NSSI的需求发送给相应NSSMF。
步骤S208a、NSSMF创建新的NSSI并配置NSSI以满足相关需求。
步骤S209a、NSMF将NSSI的需求发送给相应NSSMF。
步骤S210a、NSSMF调整和/或重配置现有NSSI以满足相关需求。
步骤S211a、NSMF将若干新创建和/或重用的NSSI组合成一个NSI。
参阅图2b，图2b为一种网络切片实例调整的流程图，如图2b所示，该网络切片实例调整中可以包含的指令可以为：创建NSI指令、调整NSI指令、创建NSSI指令、调整NSSI指令、配置NSSI指令。网络切片实例调整包括如下步骤：
步骤S201b、NSMF收到NSI调整请求或NSMF依据策略决定调整NSI。调整NSI可能包括改变NSI的容量、改变NSI内的拓扑、增加/删除NSI内的网络功能等。
步骤S202b、NSMF依据NSI调整请求确定所需调整的NSSI，并将调整请求发送至相应的NSSMF。
步骤S203b、NSSMF判断该调整请求是否可以实现。
步骤S204b、如果该调整请求不能实现，NSSMF拒绝该请求并反馈给NSMF。
步骤S205b、如果该调整请求可以实现，NSSMF判断哪些NSSI的组成构件需要调整。NSSI的组成构件可以是网络功能(NF)或嵌套的NSSI。
步骤S206b、如果该组成构件是和其他NSSI共享的，NSSMF需判断该调整是否会对其他NSSI产生不利影响，如果没有不利影响，NSSMF执行对目标组成构件的调整和/或配置。如果存在负面影响，NSSMF可能决定不执行该调整，或NSSMF创建一个新的NSSI的组成构件以满足NSSI的调整需求，此时，旧的共享NSSI组成构件会被重新配置并和所述NSSI解耦，新的NSSI构件和所述NSSI关联。如果该组成构件是所述NSSI独占的，NSSMF依据调整请求调整目标NSSI构件并配置。
参阅图2c，图2c为一种网络切片实例终结的流程图，如图2c所示，该网络切片实例 终结可以包含的指令可以为：调整NSI指令、调整NSSI指令、配置NSSI指令、终结NSI指令、终结NSSI指令。网络切片实例终结包括如下步骤：
步骤S201c、NSMF收到NSI终结请求或NSMF依据策略决定终结NSI。该NSI不再被需要。
步骤S202c、NSMF注销该NSI，需要被终结的NSI处于注销状态。
步骤S203c、NSMF确定构成所述NSI的NSSI中哪些NSSI被终结，哪些NSSI需保留。
步骤S204c、如果NSSI需要被终结，NSMF向相应NSSMF发送NSSI终结请求。
步骤S205c、NSSMF执行终结NSSI命令。
步骤S206c、如果NSSI不需被终结，NSMF向相应NSSMF发送NSSI调整和/或重配置请求。
步骤S207c、NSSMF执行调整或重配置命令。
步骤S208c、NSMF删除被终结的NSI相关信息。
上述网络切片的管理指令除了上述描述的指令以外，还可以包括但不限于：网络切片性能数据索取、网络切片告警数据索取，网络切片子网性能测量指令、网络切片子网性能阈值监视指令、网络切片子网故障索取指令等。
参阅图3，图3为本申请提供的一种网络切片管理系统结构示意图，如图3所示，该系统包括：CSMF实体、NSMF实体和NSSMF实体。接口1：CSMF和NSMF之间的接口，用于CSMF向NSMF发送网络切片管理指令和指令执行条件参数，用于NSMF向CSMF反馈管理指令执行结果，用于NSMF向CSMF上报管理数据。接口2：NSMF和NSSMF之间的接口，用于NSMF向NSSMF发送网络切片子网和/或网络功能管理指令和指令执行条件参数，用于NSSMF向NSMF反馈管理指令执行结果，用于NSSMF向NSMF上报管理数据。在实际应用中，上述NSSMF可以为多个实体，多个NSSMF实体可以通过接口2与NSMF实体连接，当然在组网时，多个NSSMF实体还可以通过其他与NSMF实体连接的设备与NSMF实体连接。
参阅图4，图4为本申请实施例提供的一种网络切片时间管理方法的流程示意图，如图4所示的实施例在如图3所示的系统结构中实现。如图4所示，包括如下步骤：
步骤1、NSMF收到NSI管理指令消息，或NSMF依据内部策略决定对NSI的管理指令消息，NSMF判断该管理指令可以执行。
步骤2、NSMF启动计时器。该计时器可以是NSMF内部的计时模块，也可能是外部的和NSMF有接口的计时模块。
步骤3、NSMF依据NSI管理指令消息、网络资源使用情况、现有NSSI/NF、NST、NSST等的信息，编排对组成该NSI的各NSSI和/或NF的需求。并生成相应的NSSI和/或NF的管理指令。
上述步骤2和步骤3在时序上可以同时发生，也可以先后发生，这里仅仅是为了方便说明采用步骤2以及步骤3的编号，上述编号并不表示时序上的顺序。
步骤4、NSMF停止计时器，记录NSI设计阶段所耗费的时间。
步骤5、NSMF启动计时器。
步骤6、NSMF向NSSMF发送NSSI/NF管理指令。
步骤7、NSSMF接收到管理指令后，启动计时器，依据NSSI和/或NF的管理指令，编排生成对NF的具体需求、部署实现，并分别记录这两个阶段所花费的时间。
步骤8、NSSMF向NSMF反馈管理指令执行完毕。可选地，NSSMF向NSMF汇报编排和部署实现分别所花费的时间。
步骤9、NSMF停止计时器，记录NSSI/NF部署阶段所耗费的时间。
下述步骤10-步骤14为可选步骤，即业务配置和测试阶段可能计入管理指令执行时间，也可能不计入执行时间。
步骤10、NSMF启动计时器。
步骤11、NSMF向NSSMF发送NSSI/NF业务配置消息。
步骤12、NSSMF依据接收到的业务配置消息，进行业务配置，并向NSMF反馈业务配置完毕。
步骤13、NSMF向NSSMF发送测试任务，确认完整的NSI能够正常工作。
步骤14、NSMF停止计时器，记录业务配置、测试阶段所耗费的时间。
步骤15、NSMF记录完整的NSI管理指令执行时间，即上述设计、编排阶段，NSSI/NF部署阶段，(可选的)业务配置、测试阶段所耗费的时间之和。
如图4所示的实施例提供的技术方案中，运营商和设备商能够知道针对每个管理指令在各阶段的执行时间，以便于运营商和设备商进行针对性的优化，同时使运营商能够估计新业务的TTM(英文：Time To Market，上市时间)等信息，所以其能够对上述时间进行管理。
可选的，NSMF、NSSMF计算出各阶段的执行时间后，可能将这些时间记录在NSMF、NSSMF内部的存储器内，也可能将这些信息通过接口记录到外部存储器中。NST、NSST的作用：网络切片模板是为了某一类型业务设计的切片模板，其中包括了组成该网络切片所需的网络切片子网、网络功能、拓扑、可使用的网络资源的上下限等信息。例如，当NSMF决定创建NSI时，检查是否可遵循某NST创建NSI以满足需求，如果存在该NST，则NSMF依据模板内的信息，确定NSI的具体参数。通常地，依据同一NST编排出的切片管理指令执行时间具有很强的相关性。如果NSMF依据NST执行网络切片管理命令，NSMF在记录管理指令执行时间时，会和相应NST关联。
参阅图5，图5提供一种网络切片管理指令执行时间查询、上报的方法，如图5所示，该方法在如图3所示的网络结构中实现，在一种可能的情况下，发送实体可以是CSMF，此时接收实体是NSMF，在另一种可能的情况下，发送实体可以是NSMF，此时接收实体可以是NSSMF。该方法如图5所示，包括如下步骤：
步骤S501、发送实体向接收实体发送订阅(subscribe)或查询网络切片管理指令执行时间的请求消息。如果该管理指令是创建NSI或NSSI，该消息中会携带以下信息中的至少一种：所需创建的NSI/NSSI的类型，对网络的需求，SLA(英文：Service Level Agreement，服务水平协议)指标等信息；如果该管理指令是调整NSI或NSSI，该消息中会携带以下信息中的至少一种：NSI或NSSI的身份标识信息，调整的类型，如扩展、收缩、更新等，调整涉及的SLA变化情况等。该请求消息中还可能携带估计指示标识，该估计指示标识用于 指示接收实体上报的是记录的历史管理指令执行时间还是依据现有资源使用情况和历史数据预测出的管理指令执行时间。
步骤S502、当接收实体仅对发送实体提供历史信息时，执行步骤S503，当接收实体需预估即时的管理指令执行时间时，检查当前计算、存储、网络等资源的使用情况及现有网络功能/网络切片子网实例的运行情况。
步骤S503、当接收实体仅对发送方提供历史信息时，接收方从数据库中读取和发送方需求相匹配的网络切片管理指令的执行时间。当接收实体需预估即时的管理指令执行时间时，接收实体依据发送方的需求、历史数据、当前的资源使用情况通过内部算法估计管理指令的执行时间。
步骤S504、如果接收实体在步骤S501中接收到的是查询请求，则接收实体向发送实体上报所请求的管理指令执行时间。可选地，接收实体可上报的可以是最大执行时间、最小执行时间、平均执行时间或以上内容的任意组合。如果接收实体在步骤S501中接收到的是订阅请求，则接收实体在上报条件满足时，上报所需的管理指令执行时间，可选地，接收实体可上报的可以是最大执行时间、最小执行时间、平均执行时间或以上内容的任意组合。

步骤S601、在一种可能的情况下，发送实体发送网络切片管理指令消息给接收实体，该消息中携带所述管理指令执行所需时间的Quota(配额)，即规定了接收实体需要在规定的时间配额内完成所述管理指令。该配额可以指定所述管理指令需在配额规定的时间段内执行完毕。可选地，该配额可以为空，也可以是无限长，即此时发送方不规定接收实体的执行时间长短。
步骤S602、在另一种可能的情况下，接收实体根据预先设定的自动管理策略，决定执行网络切片管理指令，接收实体依据预设策略，检查该管理指令的执行时间Quota。该配额可以指定所述管理指令需在配额规定的时间段内执行完毕。可选地，该配额可以为空，也可以是无限长，即此时发送方不规定接收实体的执行时间长短。
步骤S603、当接收实体收到和/或确定多项网络切片管理指令消息(所述网络切片管理指令可能是针对某一NSI/NSSI的管理指令，也可能是针对若干NSI/NSSI的管理指令)，且接收实体无法同时执行所有管理指令时，接收实体检查对应的执行时间Quota，按配额时间长短，对管理指令的执行顺序进行排序。
步骤S604、当网络切片的管理指令由发送实体发送，即执行步骤S601，且该指令不能被立即执行时，接收实体向发送实体反馈推迟执行管理指令。
步骤S605、接收实体依顺序执行网络切片管理指令。
