Description

意图状态管理方法及网元、系统
本申请要求于2020年02月29日提交中国国家知识产权局、申请号为202010132739.3、发明名称为“意图状态管理方法及网元、系统”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
本申请涉及网络管理领域，尤其涉及一种意图状态管理方法及网元、系统。
背景技术
随着网络功能虚拟化(network functions virtualization，NFV)和网络切片等第五代(5 th generation，5G)移动通信领域关键技术的兴起，网络变得更加灵活和强大，但依旧非常复杂。目前提出了体验式网络智能(experiential networked intelligence，ENI)，其定义了一个基于观察方向决定行为控制模型的认知网络管理体系架构。它使用人工智能(artificial intelligence，AI)技术和情境感知策略，根据用户需求、环境条件和业务目标的变化调整提供的服务。这能够帮助运营商自动化其网络配置和监控过程，从而减少运营支出并改善其网络的使用和维护。
意图创建设备向ENI发送意图(intent)，ENI的功能模块编排意图为可执行的指令，发送给意图作用设备执行。其中，如图1所示的意图的各状态间相互转化的示意图，目前意图分为激活态(active)和非激活态(inactive)两种状态。当意图处于active状态时，表明意图对应的操作正在被ENI执行。当意图处于inactive状态时，表明ENI保留了该意图的上下文信息，但是意图对应的操作及命令并没有被ENI以及意图作用设备所执行。由于ENI保留了该意图的上下文信息，意图创建设备可以发出激活指令，激活处于inactive状态的意图。
然而，意图创建设备仅仅是基于意图管理需要发出上述激活指令，而ENI并不知道激活该意图后，该意图是否能够被ENI执行。从而ENI会一直执行该意图，导致浪费网络资源。

如图4所示，为具体示例的ENI融入无线网络管理的示意图，在网络设备管理领域，可以将ENI的功能模块嵌入网元管理系统(element management system，EMS)(即第一网元)。网络管理系统(network management system，NMS)(即第二网元)向EMS发送意图，EMS对意图进行转译及执行，将最终生成的命令发送给网络设备(network equipment，NE)(即第三网元)。NE执行完命令，最终达成意图。
然而，当NE的网络状态不允许时，会导致意图长时间未被满足时，但意图一直处于active状态，EMS会一直执行此意图对应的操作，NE也会一直执行此意图对应的命令，导致浪费网络资源。且第二网元并不知晓网络的状态，不能对意图的状态做出合理的调整。
基于此，本申请实施例提供一种意图状态管理方案，通过监测意图对应的网络参数值，在意图的达成条件未被满足时，暂停执行意图，可以节省第一网元的网络资源，且在意图的达成条件再次被满足或者意图被修改时，使得意图进入激活态，可以及时地调整意图的状态，提高意图执行的效率。
需要说明的是，本申请所有实施例中涉及的第一网元可以为图4中的网元管理系统，第二网元可以为图4中的网络管理系统，第三网元可以为图4中的网络设备。
如图5所示，为本申请实施例提供的意图状态管理方法的流程示意图，该方法可以包括以下步骤：
S101、第一网元获取意图对应的第一网络参数值。
随着机器学习和大数据分析等技术的发展，基于意图的网络管理在无线网络中也得到应用，旨在减少人机交互并提高网络性能。与现有的基于人的网络管理相比，基于意图的网络管理使用简单的指令，告诉网络“做什么”而不是“怎么做”，以减少大规模的手动决策时的不准确性。告诉网络“做什么”，即要实现的意图，例如“提升x区用户视频业务体验”。为了方便意图的管理，可以对意图进行标识，每个意图对应有一个唯一的意图标识。意图的达成条件是指意图具体要达成的效果，也可以称为意图目标。
第一网元在执行意图前，从第二网元或者本地获得意图对应的网络参数以及意图的达成条件(或者称意图目标)。意图对应的网络参数包括意图对应的对象标识，以及具体的网络参数。可以包括一个或多个具体的网络参数。该网络参数可以是任何与网络相关的参数，例如吞吐率、丢包率等。需要说明的是，该具体的网络参数是该意图对应的网络参数，是意图执行时需要获取的网络参数。例如，意图的达成条件是某个地理区域内N个基站的吞吐率提高20％，则意图对应的对象标识是某个地理区域内的N个基站，意图对应的网络参 数是该地理区域内的N个基站的吞吐率情况。
第一网元在执行意图时，需要获取意图对应的第一网络参数值。该第一网络参数值是当前该意图对应的网络参数值。
S102、第一网元根据意图对应的第一网络参数值，确定意图的达成条件未被满足。
意图的达成条件与意图对应的网络参数密切相关，如果只有部分对象的网络参数达到所要求的网络参数阈值(例如上述示例中的提高20％)，或者该意图相关的所有对象的网络参数均未达到所要求的网络参数阈值，则可以认为意图的达成条件未被满足
在上述示例中，该地理区域内N个基站的吞吐率提高了15％，或者只要M个基站的吞吐率提高了20％，M<N，均认为意图的达成条件未被满足。
实际的网络参数值是指第三网元执行意图对应的命令时的实际的网络参数值。第一网元可以从第三网元获取意图对应的第一网络参数值。
S103、第一网元暂停执行意图。
第一网元在确定意图的达成条件未被满足时，如果第一网元一直执行该意图，则会浪费网络资源，因此，第一网元暂停执行该意图。
第一网元暂停执行该意图，还可以设置该意图为休眠状态。在该休眠状态，保留意图的上下文信息，且当意图对应的网络参数值可满足意图的达成条件，或者意图被修改时，可以激活该意图。
S104、第一网元向第二网元发送第一通知消息，该第一通知消息用于通知意图进入休眠状态。
相应地，第二网元接收该第一通知消息。第一网元暂停执行该意图，需要及时通知第二网元，以使第二网元及时获得意图的状态。
S105、意图的达成条件被满足或者意图被修改时，第一网元将休眠状态设置为激活态。
由于意图的达成条件未被满足，意图被暂停执行，并进入休眠态。然而，第三网元执行意图对应的命令时的实际的网络参数值一直处于变化中，第一网元监测意图对应的网络参数值，当未来时间段内意图对应的网络参数值使得意图的达成条件能够被满足时，第一网元可以自动激活该意图，即将休眠状态设置为激活态，以使得意图可以被及时执行。
如前所述，第一网元已经通知第二网元意图进入休眠态，该意图被暂停执行，第二网元可请求修改该意图，例如，修改该意图，以提高该意图占用的网络资源率，则第一网元可修改该意图，意图被修改后，即进入激活态，以使得意图可以被重新执行。
可以看出，意图处于inactive态时，第二网元也可以激活该意图，然而第二网元仅仅是发出激活指令，激活该意图，而不对该意图进行任何修改或改动。如果根据意图对应的第一网络参数值，确定意图的达成条件未被满足，意图进入休眠态，第二网元激活该意图，则第一网元一直执行该意图，但该意图不能成功被执行，则浪费网络资源。
根据本申请实施例提供的意图状态管理方法，通过监测意图对应的网络参数值，在意图的达成条件未被满足时，暂停执行意图，可以节省第一网元的网络资源，且在意图的达成条件再次被满足或者意图被修改时，使得意图进入激活态，可以及时地调整意图的状态，提高意图执行的效率。
如图6所示，为本申请实施例提供的意图状态管理方法的又一流程示意图，该方法可 以包括以下步骤：
S201a、第二网元向第一网元发送意图创建请求，该意图创建请求包括第二网元创建的意图的进入休眠状态等待时间窗的信息，进入休眠状态等待时间窗的信息包括窗口长度。
第二网元作为意图的创建者，可以向第一网元发送意图创建请求，请求创建意图。该意图创建请求可以包括意图标识，意图的达成条件等。
在本实施例中，该意图创建请求还包括该意图进入休眠状态等待时间窗的信息，该进入休眠状态等待时间窗的信息用于指示需要等待多长时间意图可以进入休眠状态。具体地，该进入休眠状态等待时间窗的信息包括进入休眠状态等待时间窗的窗口长度。
该意图创建请求针对该意图配置了进入休眠状态等待时间窗的窗口长度，每个意图对应的窗口长度可不同，从而实现了该窗口长度的灵活配置。
S201b、第一网元向第二网元发送意图创建响应。
该步骤是可选的，图中以虚线表示。该意图创建响应用于指示第二网元接收到该意图创建请求，或者指示意图创建成功或失败。
S202、第二网元向第一网元发送意图执行请求，意图执行请求包括意图对应的网络参数，以及意图的达成条件。
意图创建完成后，第二网元可以立即请求执行该意图，或者根据需要触发请求执行该意图。第二网元可以向第一网元发送意图执行请求，请求第一网元执行该意图。
第一网元执行该意图，是指翻译该意图并对意图进行编排等操作，编排为第三网元可执行的命令，并传输给第三网元执行。
执行意图对应的操作时，需要监测意图对应的网络参数值，判断意图的达成条件能否被满足。因此，该意图执行请求包括意图对应的网络参数，以及意图的达成条件。
S203、第一网元从第三网元获取意图对应的网络参数的初始值。
实际的网络参数值是指第三网元执行意图对应的命令时的实际的网络参数值。第一网元可以从第三网元获取意图对应的网络参数的初始值。
S204、若意图对应的网络参数的初始值小于或等于第一阈值，第一网元启动计时器，计时器的计时时长为进入休眠状态等待时间窗的窗口长度。
根据获取的意图对应的网络参数的初始值，判断如果意图对应的网络参数的初始值小于或等于第一阈值，可以初步判断意图的达成条件未被满足。然而由于网络参数值是一直变化的，根据一次获得的意图对应的网络参数值，即确定该意图的达成条件不能被满足，从而暂停执行该意图，可能会造成失误的判断，从而影响意图执行的效率。因此，第一网元可以启动计时器，判断在一个计时时长内，该意图的达成条件能否被满足。
该计时器的计时时长即为进入休眠状态等待时间窗的窗口长度，该窗口长度是在意图创建时配置的。
S205、若在计时时长到达时，意图对应的第一网络参数值仍小于或等于第一阈值，第一网元确定意图的达成条件仍未被满足。
在该计时时长内，第一网元周期性地或不定时地从第三网元获取新的意图对应的第一网络参数值，并且判断意图对应的第一网络参数值是否仍小于或等于第一阈值，若在计时时长到达时，意图对应的第一网络参数值仍小于或等于第一阈值，第一网元确定意图的达 成条件仍未被满足。若在计时时长内，意图对应的第一网络参数值大于第一阈值，该可确定该意图的达成条件可被满足。
S206、第一网元设置意图的状态为休眠状态。
第一网元在确定意图的达成条件不能被满足时，设置意图的状态为休眠状态。
S207、第一网元向第二网元发送第一通知消息，第一通知消息用于通知意图进入休眠状态。
第一网元暂停执行该意图，需要及时通知第二网元，以使第二网元及时获得意图的状态。
S208、第一网元向第三网元发送指示消息，指示消息用于指示第三网元暂停执行意图对应的命令。
第一网元在暂停执行该意图后，可以向第三网元发送指示消息，指示第三网元暂停执行意图对应的命令，以节省第三网元的功耗和网络资源。
在另外的实现中，第一网元在暂停执行该意图后，也可以不向第三网元发送指示消息。第一网元暂停执行意图，则第一网元不会向第三网元发送该意图对应的命令，则第三网元在执行完第一网元在暂停执行意图之前发送的命令后，可以自行暂停执行该意图对应的命令，以节省第三网元的功耗和网络资源。
S209、第一网元从第三网元获取意图对应的第二网络参数值。
第一网元暂停执行意图后，可以试图唤醒该意图。第一网元从第三网元获取新的意图对应的网络参数值，即第二网络参数值。该第二网络参数值是意图被暂停执行后当前的该意图对应的网络参数值。
S210、第一网元根据第二网络参数值，预测意图的达成条件在第一时间段内能够被满足。
意图对应的网络参数一直在变化，第一网元根据新获得的该第二网络参数值，预测意图的达成条件在第一时间段内是否能够被满足。预测的操作与前面描述的根据意图对应的第一网络参数值确定意图的达成条件能否被满足可以不同，预测是基于该第二网络参数值，以及第一网元执行意图的动作、意图的达成条件等综合判断在一定时间段内该意图的达成条件能否被满足。
可以理解的是，上述第二网络参数值可以是一个或多个时间点获取的网络参数值，或者是一个时间点的网络参数值以及根据该时间点的网络参数值预测的多个时间点的网络参数值。即当根据某一个时间点获取的第二网络参数值，预测意图的达成条件在第一时间段内不能被满足时，即该意图不能被唤醒，则第一网元继续获取第二网络参数值。直到根据获取的一个或多个第二网络参数值，预测意图的达成条件在第一时间段内能够被满足，才唤醒该意图。
例如，根据一个或多个第二网络参数值，以及执行意图的动作，判断意图的达成条件在第一时间段内被满足的概率超过预设概率阈值，则可确定意图的达成条件在第一时间段内能够被满足。
S211、第一网元将休眠状态设置为激活态。
在预测意图的达成条件在第一时间段内能够被满足时，第一网元唤醒该意图，将休眠 状态设置为激活态。
S212、第一网元向第二网元发送第二通知消息，第二通知消息用于通知意图进入激活态。
相应地，第二网元接收该第二通知消息。
在意图进入激活态后，及时地通知第二网元，以使第二网元及时地获知意图的状态。
根据本申请实施例提供的意图状态管理方法，通过监测意图对应的网络参数值，在意图的达成条件未被满足时，暂停执行意图，可以节省第一网元的网络资源，且在意图的达成条件再次被满足时，使得意图进入激活态，可以及时地调整意图的状态，提高意图执行的效率。
基于图3所示的意图状态管理系统的架构，本申请实施例提供又一种意图状态管理方法。该方法涉及第一网元的反向规格化和输入产生(denormalization and output generation)模块(denormalization模块和output generation模块合并的模块)、cognition management模块、situational awareness模块、context awareness模块、policy management模块、数据输入和标准化(data ingestion and normalization)模块(data ingestion模块和normalization模块合并的模块)等。如图7所示，为本申请实施例提供的又一种意图状态管理方法的流程示意图，该方法可以包括以下步骤：
S301、context awareness模块向normalization模块发送意图的达成条件是否达成请求。该请求包括意图标识，意图的达成条件和应答周期。
意图的达成条件是否达成(或者意图的达成条件是否满足)与意图对应的网络参数值相关。context awareness模块可以周期性地向normalization模块发送意图的达成条件是否达成请求。该请求包括意图标识和意图的达成条件，还可以包括应答周期。该应答周期是指normalization模块向context awareness模块应答的时间范围。如果normalization模块未在该应答周期内应答，context awareness模块可以认为意图的达成条件未达成，或者发送请求失败。
normalization模块收到该请求后，向data ingestion模块转发该请求。
S302、data ingestion模块接收到该请求后，从第三网元获取意图对应的第一网络参数值，并向normalization模块发送意图的达成条件是否达成响应。normalization模块向context awareness模块转发该意图的达成条件是否达成响应。该响应包括意图标识和意图对应的第一网络参数值。
第三网元即执行第一网元编排的命令的设备。意图对应的网络参数值包括吞吐率、丢包率等。例如，若context awareness模块发送的请求中，意图的达成条件是吞吐率提高20％。第三网元接收到data ingestion模块的网络参数值获取请求后，向data ingestion模块发送当前的吞吐率值。data ingestion模块向normalization模块发送响应消息。normalization模块转发该响应消息给context awareness模块。该响应消息包括意图标识和获取的当前的吞吐率值。context awareness模块根据当前的吞吐率值和意图的达成条件，确定意图的达成条件是否达成。
S303、当意图的达成条件不被满足时，context awareness模块触发计时机制，超过计时时长意图的达成条件仍未被满足，则判定意图的达成条件短时间内暂时不可被满足。
当context awareness模块确定意图的达成条件不被满足时，开启计时器。该计时器的计时时长为进入休眠状态等待时间窗的窗口长度。在该计时时长内，context awareness模块可以一次或多次获取意图对应的第一网络参数值，若在该计时时长内，context awareness模块根据一次或多次获取意图对应的第一网络参数值，确定意图的达成条件仍未被满足，则确定意图短时间内暂时不可被满足，停止计时；若在该计时时长内，context awareness模块根据获取的意图对应的第一网络参数值确定意图的达成条件可满足，则确定意图的达成条件被达成，并停止计时器。
context awareness模块确定意图的达成条件短时间内暂时不可被满足时，将意图的状态由激活态修改为休眠态。
S304、context awareness模块向policy management模块发送意图暂停执行请求。
当context awareness模块确定意图的达成条件短时间内暂时不可被满足，如果意图状态管理系统继续执行意图的操作，则浪费资源。因此，context awareness模块向policy management模块发送意图暂停执行请求。
S305、policy management模块接收到意图暂停执行请求后，暂停执行该意图，并向context awareness模块发送意图暂停执行响应。
policy management模块是意图决策模块，获得意图对应的第一网络参数值以匹配意图执行条件(意图对应的网络参数值)，得到需要执行的命令。当前policy management模块接收到意图暂停执行请求后，暂停执行该意图。该意图暂停执行响应用于通知context awareness模块已经暂停执行该意图。
context awareness模块负责管理意图的状态。context awareness模块在接收到该响应消息后，可以将意图的状态由激活态修改为休眠态。
S306-1、policy management模块向denormalization模块发送意图通知，denormalization模块向output generation模块转发该意图通知，该通知用于通知当前意图状态为休眠状态。
policy management模块在向context awareness模块发送意图暂停执行响应后，确定意图当前的状态为休眠态，并且可以通知第二网元当前意图状态为休眠状态。policy management模块通过输出模块——denormalization模块和output generation模块向第二网元发送该通知。
S306-2、output generation模块向第二网元发送该通知。
第二网元在接收到该通知后，可以知道意图当前状态为休眠状态，也即意图状态管理系统当前不会对意图进行进一步的操作。
可以理解的是，policy management模块在向context awareness模块发送意图暂停执行响应后，policy management模块暂停执行该意图，则暂停向第三网元发送执行命令。第三网元也暂停执行命令，节省了网络资源和第三网元的功耗。
S307、policy management模块向situational awareness模块发送意图唤醒请求，该意图唤醒请求包括意图标识，意图对应的网络参数以及意图的达成条件。
在意图进入休眠状态后，policy management模块可以立即或者周期性地向situational awareness模块发送意图唤醒请求。该意图唤醒请求用于请求唤醒意图。该意图唤醒请求包括意图标识，意图对应的网络参数以及意图的达成条件。该意图唤醒请求携带的上述信息 用于situational awareness模块预判意图是否可能被唤醒。
S308、situational awareness模块向cognition management模块发送预测请求。
situational awareness模块可以根据意图对应的第二网络参数值预测意图是否能被唤醒。首先，situational awareness模块需要获取实时的以及预测的意图对应的第二网络参数值，因此，situational awareness模块向cognition management模块发送预测请求。该预测请求用于请求获取当前的以及预测的意图对应的第二网络参数值。
S309、cognition management模块向context awareness模块发送网络参数值获取请求。
cognition management模块接收situaional awareness模块发送的网络参数值获取请求后，向context awareness模块发送网络参数值获取请求。该网络参数值获取请求用于请求获取当前的意图对应的第二网络参数值。
S310、context awareness模块获取意图对应的第二网络参数值后，向cognition management模块发送网络参数值获取响应。
context awareness模块可以通过data ingestion模块和normalization模块从第三网元获取意图对应的第二网络参数值。context awareness模块获取意图对应的第二网络参数值后，向cognition management模块发送网络参数值获取响应。该网络参数值请求响应包括当前的意图对应的第二网络参数值。
S311、cognition management模块接收到context awareness模块发送的意图对应的第二网络参数值后，根据意图对应的第二网络参数值进行预测，向situational awareness模块发送预测响应。
cognition management模块接收到context awareness模块发送的意图对应的第二网络参数值后，根据意图对应的第二网络参数值对意图对应的网络参数值进行预测，即预测一段时间内的意图对应的网络参数值。然后，cognition management模块向situational awareness模块发送意图对应的网络参数值预测响应，该意图对应的网络参数值预测响应包括当前的以及预测的意图对应的网络参数值。
S312、situational awareness模块预测意图对应的网络参数值是否能达成意图的达成条件。
situational awareness模块根据接收到的意图对应的网络参数值信息(当前的以及预测的意图对应的网络参数值)以及意图的达成条件(或者称意图达成参数值)判断意图的达成条件是否达成。例如，意图的达成条件是吞吐率提高20％，假设获取当前的吞吐率为A，且预测的吞吐率为25％*A，则可以确定意图的达成条件可以达成。则situational awareness模块向policy management模块发送意图唤醒请求响应，该意图唤醒请求响应用于指示意图的达成条件可达成。
可以理解的是，policy management模块向situational awareness模块发送意图唤醒请求后，situational awareness模块第一次判断意图的达成条件未达成，则可以再执行上述步骤S308～S312。即上述步骤S308～S312是一个循环执行的动作，循环动作在situational awareness模块判断意图的达成条件可达成时停止。
S313、situational awareness模块向policy management模块发送意图唤醒响应。该意图唤醒响应包括意图标识和意图对应的第二网络参数值。
situational awareness模块向policy management模块发送意图唤醒响应，该意图唤醒响应用于指示意图的达成条件可达成。该意图唤醒响应包括意图标识和当前的意图对应的网络参数值。
S314、policy management模块向context awareness模块发送意图激活请求。该意图激活请求包括意图标识。
policy management模块在收到上述意图唤醒响应后，确定意图的达成条件可达成，则向context awareness模块发送意图激活请求。该意图激活请求用于请求激活该意图。
S315、context awareness模块接收到意图激活请求后，将意图由休眠态修改为激活态。
context awareness模块对意图的状态进行管理，且在接收到上述意图激活请求后，将意图由休眠态修改为激活态。
S316、context awareness模块向policy management模块发送意图激活请求响应。
该意图激活请求响应用于指示意图已由休眠态进入激活态。
S317a、policy management模块向denormalization模块发送决定，denormalization模块向output generation模块发送该决定对应的命令。
意图进入激活态后，policy management模块可以继续对意图进行操作。policy management模块向denormalization模块发送决定，该决定为对意图继续进行操作的结果。

如图9所示，为本申请实施例提供的意图状态管理方法的又一流程示意图。该实施例与图6～图8所示实施例不同的是，可以根据第二网元的意图修改请求，修改并激活意图，使意图从休眠状态进入激活态。具体地，该方法可以包括以下步骤：
S501a、第二网元向第一网元发送休眠时间配置请求，休眠时间配置请求包括所述第二网元创建的所有意图的所述进入休眠状态等待时间窗的信息，所述进入休眠状态等待时间窗的信息包括窗口长度。
在本实施例中，第二网元可以针对其创建的所有意图统一配置进入休眠状态等待时间窗。通过统一配置进入休眠状态等待时间窗，可以提高配置的效率。
S501b、第一网元向第二网元发送休眠时间配置响应。
该步骤是可选的操作，图中以虚线表示。该休眠时间配置响应用于指示第一网元接收 到了该休眠时间配置请求，或者用于指示休眠时间配置成功或失败。
S502、第二网元向第一网元发送意图执行请求，意图执行请求包括意图对应的网络参数，以及意图的达成条件。
该步骤的具体实现可参考图6所示实施例的步骤S202。
S503、第一网元从第三网元获取意图对应的第一网络参数的初始值。
该步骤的具体实现可参考图6所示实施例的步骤S203。

该步骤的具体实现可参考图6所示实施例的步骤S204。
S505、若在计时时长到达时，意图对应的第一网络参数值仍小于或等于第一阈值，第一网元确定意图的达成条件仍未被满足。
该步骤的具体实现可参考图6所示实施例的步骤S205。
S506、第一网元设置意图的状态为休眠状态。
该步骤的具体实现可参考图6所示实施例的步骤S206。
S507、第一网元向第二网元发送第一通知消息，第一通知消息用于通知意图进入休眠状态。

S508、第一网元向第三网元发送指示消息，指示消息用于指示第三网元暂停执行意图对应的命令。
该步骤的具体实现可参考图6所示实施例的步骤S208。
S509、第一网元从第二网元接收意图修改请求，意图修改请求用于请求修改意图的一个或多个参数：意图的达成条件，意图命令影响区域，意图优先级，意图的执行顺序。
第二网元在获知意图进入休眠状态后，可以请求修改该意图。
具体地，可以请求修改意图的达成条件。例如，在进入休眠状态前，第二网元发送的意图执行请求中携带的意图的达成条件为：某个地理区域内N台基站设备的吞吐率提高20％，然而由于根据意图对应的第一网络参数值确定该意图的达成条件不能被满足，则第二网元可以修改意图的达成条件，例如将意图的达成条件修改为：某个地理区域内N台基站设备的吞吐率提高15％。由于意图的达成条件被修改，根据该意图对应的网络参数值，确定修改后的意图的达成条件能够被满足，即能够使得该意图可能能被第一网元成功执行。
还可以请求修改意图命令影响区域。例如，根据意图对应的第一网络参数值，确定只有M台基站设备的吞吐率能够被满足，M<N，则修改意图命令影响区域，例如，修改意图的达成条件为：某个地理区域内M台基站设备的吞吐率提高20％。由于意图的达成条件被修改，根据该意图对应的网络参数值，确定修改后的意图的达成条件能够被满足，即能够使得该意图可能能被第一网元成功执行。
还可以请求修改意图优先级。具体地，提高该意图优先级，从而第一网元/第三网元可以提高该意图占用的网络资源。由于意图的达成条件被修改，根据该意图对应的网络参数值，确定修改后的意图的达成条件能够被满足，即能够使得该意图可能能被第一网元成功执行。
还可以请求修改意图的执行顺序。该意图的执行顺序被修改，例如将意图的执行顺序提前，即该意图的重要性高于其他意图，则第一网元/第三网元可以提高该意图占用的网络资源，以使得该意图被成功执行。由于意图的达成条件被修改，根据该意图对应的网络参数值，确定修改后的意图的达成条件能够被满足，即能够使得该意图可能能被第一网元成功执行。
S510、第一网元根据意图修改请求修改意图的一个或多个参数。
第一网元在接收到上述意图修改请求后，根据该意图修改请求携带的该意图的一个或多个参数，修改该意图的一个或多个参数。
S511、第一网元将休眠状态设置为激活态。
上述意图的一个或多个参数被修改后，即可以激活意图，并将休眠状态设置为激活态。
S512、第一网元向第二网元发送意图修改响应。
该步骤是可选的，图中以虚线表示。该意图修改响应用于指示意图的一个或多个参数被修改。
根据本申请实施例提供的意图状态管理方法，在意图的达成条件被满足或者意图被修改时，第一网元将休眠状态设置为激活态。通过监测意图对应的网络参数值，在意图的达成条件未被满足时，暂停执行意图，可以节省第一网元的网络资源，且在意图被修改时，使得意图进入激活态，可以及时地调整意图的状态，提高意图执行的效率。
