具体实施方式
为了使得本公开的目的、技术方案和优点更为明显，下面将参照附图详细描述根据本公开的示例实施例。显然，所描述的实施例仅仅是本公开的一部分实施例，而不是本公开的全部实施例，应理解，本公开不受这里描述的示例实施例的限制。
在本说明书和附图中，具有基本上相同或相似步骤和元素用相同或相似的附图标记来表示，且对这些步骤和元素的重复描述将被省略。同时，在本公开的描述中，术语“第一”、“第二”等仅用于区分描述，而不能理解为指示或暗示相对重要性或排序。
随着信息技术尤其是互联网技术的发展，用于实现信息化、远程管理控制和智能化的网络的物联网技术正逐渐成熟。物联网利用局部网络或互联网等通信技术把传感器、控制器、机器、人员和物等通过新的方式联接在一起，形成人与物、物与物相联。物联网是互联网的延伸，它包括互联网及互联网上所有的资源，兼容互联网所有的应用。随着物联网技术在各个领域的应用，出现了诸如智能家居、智能交通、智慧健康等各种新的应用领域。
图1A示出了根据本公开的实施例的物联网示意性的架构图。图1B示出根据本公开的实施例的各个设备之间的连接的示意图。图1C示出了根据本公开的实施例的ASN-AE的界面图。图1D示出了根据本公开的实施例的温 度传感器移动前后的示意图。
图1A公开了本公开实施例的物联网示意性的架构图。如图1A所示，各种终端的客户端设备接入网络，并且通过网络接入到通用服务层，而通用服务层支持各种应用，从而形成了终端+网络+应用的架构。例如，在智能家居领域，各种家用设备可以利用局域网(LAN)接入通用服务平台，这样的局域网接入可以采用诸如无线或者有线方式。可选地，所述局域网可以是个域网(PAN)，例如以无线个域网(WPAN)为例，可以采用Bluetooth、IrDA、Home RF、ZigBee、或UWB(Ultra-Wideband Radio)等各种技术来实现接入。
如前所述，当物联网实体(例如，物联网终端设备或者节点设备中的软件模块)将数据或信息传输到通用服务实体后，该数据或信息可以作为单独的资源进行存储。此外，物联网实体可以向通用服务实体发送请求，从而更新通用服务实体上存储的与该物联网实体对应的资源，以便反映该物联网实体所运行的设备的状态。这种更新可以是实时的或者是周期性的，也可以由某一条件进行触发。由此，与该通用服务实体通信的其他物联网实体可以通过访问更新的资源，而获悉该物联网实体所对应的设备的状态；或者，与该通用服务实体通信的其他物联网实体可以对更新的资源进行操作。应注意，这里所称的资源，包括各种实体(例如，可以体现为物联网设备中的软件模块，诸如AE、CSE等实体)的资源。实体可以表示一通信设备的软件模块，而通用服务实体可以表示服务平台的软件模块，而服务平台可以是本地的或者是远程的。可选地，对更新的资源进行操作包括，例如，获取更新的资源的信息、删除更新的资源的信息、将更新的资源的信息通知给第三方，或者基于更新的资源的信息对其他资源进行操作。
在本公开中，所描述的实体，例如应用实体AE，通用服务实体CSE，以及数据等都可以通过资源进行表示。具体地，资源可以包括属性和子资源，其中属性用来存储资源相关的信息(例如，资源的标识符、资源对应的AE的物理位置、资源的状态信息等)，子资源是资源的下一级资源，资源包括指向下一级资源的索引。
应用实体AE可以包括应用服务节点中的应用实体ASN-AE和应用专用节点中的应用实体ADN-AE。应用实体ADN-AE可以是温度传感器、湿度传感器、空气进化器、智能灯泡等。应用实体ASN-AE可以为电视、智能家电 设备(例如，智能冰箱、智能微波炉等)、充电汽车、台式电脑、笔记本电脑、智能手机、平板电脑、音乐播放器(例如mp3播放器等)以及其他包括处理器和存储器的终端(例如，移动终端，智能终端)。应用实体ASN-AE上可以安装物联网相关应用，以通过通用服务实体CSE来对应用实体ADN-AE的操作进行设置。应用实体ASN-AE可以向通用服务实体CSE发送创建相关应用实体ADN-AE的订阅的请求。
参考图1B，通用服务实体CSE、应用服务节点中的应用实体ASN-AE(例如，手机终端)、应用专用节点中的第一应用实体和应用专用节点中的第二应用实体可以通过网络连接。上述各设备之间可以直接或间接地互相通信，例如，通过网络互相发送和接收数据和/或信号。
网络可以是基于互联网和/或电信网的物联网(Internet of Things)，其可以是有线网也可以是无线网，例如，其可以是局域网(LAN)、城域网(MAN)、广域网(WAN)、蜂窝数据通信网络等能实现信息交换功能的电子网络。
在一些实施例中，应用实体ADN-AE可以是温度计、空调、风扇、灯等小型物联网设备。当这些ADN-AE注册在CSE之后，CSE可在其上创建对应的资源。CSE通过对应资源的操作来控制这些ADN-AE。
在一些实施例中，操作者在ASN-AE进行操作(例如编辑智能场景)，向CSE发送创建智能场景的请求(例如，创建进程管理资源的请求、创建动作资源的请求、创建状态资源的请求等等)，进而使得各个ADN-AE可以联动。
例如，在图1C中涉及的智能家居场景中，各种物联网设备之间可以进行联动。ASN-AE可以设置如图1C所示的智能场景来控制物联网设备，这些物联网设备包括：温度传感器、空调设备、和风扇设备。温度传感器、空调设备和风扇设备均放置在客厅中。例如，可以设置这样的智能家居场景：当温度传感器检测到环境温度大于31摄氏度时，开启空调，并将风扇调节至自然风一档并开启摆头。那么当温度传感器监测到客厅内环境温度大于31摄氏度时，客厅内的空调就会开启，风扇调节至自然风一档并开启摆头，从而使客厅内的环境温度降低，以满足用户降温的目的。
然而，在这样的场景中，如图1D所示，用户将温度传感器移动到阳台，通过ASN-AE(如终端设备(例如手机APP))将温度传感器的位置“客厅”取消勾选，去勾选“阳台”，从而完成所述温度传感器的资源属性中位置信 息的变更，然而此时ASN-AE却不会收到任何订阅通知来告知用户之前设置的智能场景可能相应的变化，导致此时的智能场景实际变成了“阳台温度大于31摄氏度时开启客厅内的空调”，这与用户设置的智能家居场景的初衷不相符，不符合用户的实际操作实践，给用户带来不好的体验。
针对上述问题，本公开实施例提供了一种新型订阅应用的方法。利用本公开提供的新型订阅应用的方法，可对物联网设备的资源的属性的变更进行订阅，并在其资源的属性变更的情况下向被通知的应用实体发送与该物联网设备相关联的动作资源的订阅通知，从而使用户可以及时获知相关的动作资源及其是否有效，并且还可以自主决定部分相关的动作资源是继续生效还是失效，进而更加符合用户的实际操作实践。
具体而言，所述新型订阅应用的方法分为由通用服务实体(Common Services Entity，CSE)执行的订阅通知的方法、由应用服务节点中的应用实体(CSE which resides in the Application Service Node，ASN-AE)执行的订阅通知的方法以及由用于物联网的终端执行的方法。下面对上述方法进行详细地说明。
图2示出了根据本公开实施例的一种由应用服务节点中的应用实体执行的订阅通知的方法的流程图。
参照图2，在S210，所述ASN-AE可以发送创建动作资源的请求，其中，所述动作资源可以与被监控的应用实体(例如，ADN-AE)相关联，被监控的应用实体的资源属性被监控以用于订阅通知。
作为示例，所述被监控的应用实体可以包括温度传感器、空调设备、空气净化设备、台灯设备以及门窗传感器。
作为示例，所述ASN-AE可以是手机中的应用程序。
作为示例，所述ASN-AE可以向CSE发送创建“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的空调”动作资源的请求，其中，所述温度传感器的资源属性被监控以用于订阅通知。
在S220，所述ASN-AE可以接收与被监控的应用实体相关联的动作资源对应的订阅通知。
根据本公开实施例，不仅可以由上述ASN-AE来接收订阅通知，还可以有公共服务实体CSE来接收订阅通知，在此仅作为示例，由上述ASN-AE来接收订阅通知来进行相关方案的描述。
作为示例，被监控的应用实体可以是温度传感器。所述ASN-AE可以接收到与温度传感器相关联的动作资源对应的订阅通知。具体地，假设关于温度传感器设置了以下动作资源：
动作资源1：“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的空调设备”；
动作资源2：“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的窗户设备”；
动作资源3：“当温度传感器监测到客厅内环境温度小于15摄氏度时，关闭客厅内的窗户”；
则所述ASN-AE可以接收到与上述动作资源1至3中至少一个对应的订阅资源。
根据本公开实施例，所述订阅通知可以包括以下各项中的至少一项：关于被监控的应用实体的当前动作资源失效的通知、关于与被监控的应用实体相关联的动作资源列表的通知、以及关于所述被监控的应用实体的动作资源重新生效的通知。
作为示例，当温度传感器从客厅移到卧室时，则所述ASN-AE可以收到关于温度传感器的当前动作资源1失效的通知。
作为示例，当温度传感器从客厅移到卧室时，则所述ASN-AE可以收到与温度传感器相关联的动作资源2至3列表的通知。可选地，在所述通知中，可以在与动作资源对应的位置处设置让用户选择以确定相应的动作资源是继续生效还是失效的按钮。
作为示例，当温度传感器从客厅移到卧室后又重新将温度传感器从客卧室到客厅时，则所述ASN-AE可以收到关于温度传感器的动作资源3重新生效的通知。
根据本公开实施例，所述在发送创建动作资源的请求之后还可以包括：发送创建订阅资源的请求，所述订阅资源的事件通知标准条件中包括要被监控的应用实体的标识符。
作为示例，所述ASN-AE可以向CSE发送创建订阅资源的请求，在所述请求中指明需要被监控的应用实体如温度传感器。
作为示例，所述订阅资源的事件通知标准条件(eventNotificationCriteria conditions)中可以包括被监控的应用实体(如温度传感器)的标识符(如 AE-ID-Stem)。
根据本公开实施例，所述订阅通知可以由被监控的应用实体的重新注册导致的该应用实体的属性变更而触发的，关于应用实体的注册过程后续将结合图4进行介绍，这里不再赘述。
作为示例，被监控的应用实体可以是空调设备和空气净化设备。
作为示例，所述订阅通知可以是由空调设备的重新上电后导致与空调设备对应的属性变更而触发的。
作为示例，所述订阅通知可以是由空气净化设备被卖方卖给买方，由买方上电之后触发的，并且订阅通知发给的是卖方的终端设备(例如手机APP)。
根据本公开实施例，在接收与被监控的应用实体相关联的动作资源对应的订阅通知之前还可以包括：发送更改被监控的应用实体的资源属性的请求；接收被监控的应用实体的资源属性变更的响应。
作为示例，被监控的应用实体可以是温度传感器，在此情况下，所述ASN-AE可以向CSE发送更改温度传感器的资源属性中位置信息的请求，例如将温度传感器之前的位置“客厅”取消勾选，去勾选“阳台”，从而完成所述温度传感器的资源属性中位置信息的变更。
作为示例，在CSE端处理完毕上述更改请求后，就会向所述ASN-AE(如手机APP)发送变更成功响应，则此时，所述ASN-AE就会接收到所述ADN-AE(如温度传感器)的资源属性变更的响应。
根据本公开实施例，所述订阅通知可以是由被监控的应用实体的资源属性变更触发的。
作为示例，在被监控的应用实体为温度传感器的情况下，所述订阅通知可以由温度传感器的资源属性中的位置信息的变更来触发，例如，温度传感器从客厅移到了卧室并在终端设备(如手机APP)完成位置的更改之后触发了所述订阅通知。
根据本公开实施例，所述动作资源是在所述被监控的应用实体完成初始注册之后创建的，关于应用实体的注册过程后续将结合图4进行介绍，这里不再赘述。
作为示例，所述动作资源也可以由被监控的应用实体完成重新注册之后创建。也就是说，所述动作资源是在被监控的应用实体至少完成一次注册之后创建。
作为示例，在温度传感器和空调设备完成向CSE的注册之后，所述ASN-AE可以向CSE发送创建“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的空调”的动作资源的请求。
以上结合图2详细描述了由应用服务节点中的应用实体ASN-AE(如手机APP)执行的订阅通知的方法。由以上内容可知，在ADN-AE完成注册之后，ASN-AE可以向CSE发送创建动作资源的请求，并在所述请求中包括与被监控的应用实体相关联的信息，从而在被监控的应用实体的属性变更之后，能够及时触发订阅通知，从而使ASN-AE(如手机APP)及时接收到与被监控的应用实体的动作资源对应的订阅通知，进而使用户能够及时知道之前设置的与被监控的应用实体相关的智能场景，以便决定相关智能场景继续有效还是失效，这不仅符合用户的实际操作实践，也能够提高用户的物联网体验。
在以上结合图2详细描述了由ASN-AE执行的订阅通知的方法之后，接下来结合图3详细描述一种由通用服务实体执行的订阅通知的方法。
图3示出了根据本公开实施例的一种由通用服务实体执行的订阅通知的方法的流程图。
参照图3，在S310，可以至少部分地基于与被监控的应用实体相关联的动作资源，来创建与所述被监控的应用实体相关联的订阅资源。
根据本公开实施例，在所述通用服务实体CSE上可以创建有与多个应用实体相关联的多个动作资源，所述被监控的应用实体为所述多个应用实体之一。
作为示例，在CSE上可以创建有与温度传感器、湿度传感器、空调设备及加湿设备相关的以下动作资源：
动作资源1：“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的空调设备”；
动作资源2：“当温度传感器监测到客厅内环境温度小于16摄氏度时，关闭客厅内的空调设备”；
动作资源3：“当湿度传感器检测到客厅内湿度小于25％时，开启客厅内的加湿设备”；
在被监控的应用实体是温度传感器的情况下，上述动作资源1至3中的动作资源1和2与温度传感器相关，因此，可以基于动作资源1和/或2来创建与温度传感器相关联的订阅资源。
根据本公开实施例，所述与被监控的应用实体相关联的动作资源的创建可以包括：响应于接收到创建动作资源的请求，创建所述动作资源，所述动作资源与被监控的应用实体相关联。
作为示例，如上述动作资源1的创建可以是响应于从ASN-AE接收到创建以下动作资源的请求：“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的空调设备”，由CSE来创建所述动作资源，并且上述动作资源是与被监控的应用实体(如温度传感器)相关联的。
根据本公开实施例，所述订阅资源可以包括事件通知标准属性，所述订阅资源的事件通知标准可以包括注册监控属性，其中，所述创建与所述被监控的应用实体相关联的订阅资源还可以包括：将所述被监控的应用实体的标识符添加到所述注册监控属性对应的订阅监控列表中。
根据本公开实施例，如下表1和2所示，其中，表1示出了订阅(<subscription>)资源的相关的属性，包括事件通知标准(eventNotificationCriteria)属性，表1中所示的内容仅是示例性的，其还可以包括其他的内容，这里不在赘述。
表2示出了订阅资源包括的事件通知标准属性中包括的相关属性(如注册监控(regMonitor)属性)，表2中所示的内容仅是示例性的，其还可以包括其他的内容，这里不在赘述。
如表2所示，可以将被监控的应用实体的标识符(如温度传感器的AE-ID-stem)添加到所述regMonitor属性的对应的订阅监控列表中。

在表1和表2中，值“0..1”表示子资源/属性可能存在；值“0..n”表示子资源/属性可能存在，如果存在，则支持多个实例；用(L)后固定的属性 多重性表示它是一个值列表；RW表示读写。
根据本公开实施例，如表2所示，所有需要被监控的应用实体的标识符都会被添加到上述订阅监控列表中(即AE-ID-Stem列表)。具体而言，CSE会将需要被监控的应用实体的标识符添加在<CSEBase>或<remoteCSE>下，以对被监控的应用实体的重新注册状态进行监控，而上述重新注册状态可以是被监控的应用实体的重新注册触发的，也可以是被监控的应用实体的资源属性变更触发的。
作为示例，上述CSE创建与温度传感器和/或空调设备的资源相关联的订阅资源之后，就会把温度传感器和/或空调设备的标识符放在<CSEBase>或<remoteCSE>下，即添加到订阅监控列表中，从而实现对其重新注册状态进行监控。
根据本公开实施例，所述创建与所述被监控的应用实体相关联的订阅资源可以包括：响应于接收到创建对被监控的应用实体的订阅资源的请求，创建对所述被监控的应用实体的资源相关联的订阅资源，并将所述被监控的应用实体的标识符添加到所述订阅监控列表中。
作为示例，ASN-AE可以向CSE发送创建对温度传感器的订阅资源的请求，而CSE接收到上述请求后，可以创建对温度传感器的资源相关联的订阅资源，并将温度传感器的标识符(如AE-ID-stem)添加到订阅监控列表中(即，将该标识符添加在<CSEBase>或<remoteCSE>下)，以实现对温度传感器的资源的监控。
返回参照图3，在创建订阅资源之后，在步骤S320，在所述被监控的应用实体的资源属性变更的情况下，可以向被通知的应用实体发送与所述被监控的应用实体相关联的动作资源对应的订阅通知。
作为示例，被监控的应用实体可以是温度传感器，当温度传感器的资源属性变更的情况下，CSE可以向如ASN-AE或中间节点(如网关)中的应用实体发送与温度传感器相关联的动作资源对应的订阅通知。
根据本公开实施例，所述被监控的应用实体的资源属性变更的确定可以包括：接收被监控的应用实体的重新注册请求；将重新注册的被监控的应用实体的资源属性与所述被监控的应用实体重新注册之前的资源属性进行比较，确定所述被监控的应用实体的资源属性是否变更，其中，关于应用实体的注册过程后续将结合图4进行介绍，这里不再赘述。
作为示例，被监控的应用该实体可以是带有全球定位***(Global Positioning System，GPS)功能的空气净化器。在这种情况下，空气净化器在移动前位于客厅，并向CSE发送初始注册请求，CSE接收所述初始注册请求后对其进行注册，此时注册的空气净化器的资源的属性包括位置信息(客厅)、标识符等；在将所述空气净化器移动到卧室后，空气净化器上电后向CSE发送重新注册请求，CSE接收到所述重新注册请求后对其进行重新注册，此时空气净化器的资源的属性包括位置信息(卧室)、标识符等，然后CSE将重新注册前后的空气净化器的资源进行比较，此时，空气净化器的资源属性发生了变更，即可以确定空气净化器的资源属性变更。
作为示例，被监控的应用该实体可以是智能灯泡。在这种情况下，智能灯泡向CSE发送初始注册请求，CSE接收所述初始注册请求后对其进行注册，此时，智能灯泡的资源的属性包括位置信息(如客厅)、标识符等；然后在客厅断电又重新上电之后，智能灯泡向CSE发送重新注册的请求，CSE接收到所述重新注册请求后对其进行重新注册，此时，灯泡的资源的属性包括位置信息(如客厅)、标识符等；然后CSE将重新注册前后的智能灯泡的资源进行比较，此时，智能灯泡的资源属性发未发送变更，即可以确定智能灯泡的资源属性未变更。
可选地，根据本公开实施例，所述被监控的应用实体的资源属性变更的确定可以包括：响应于接收到更改所述被监控的应用实体的资源属性的请求，来确定对所述被监控的应用实体的资源属性进行变更。
作为示例，被监控的应用实体可以是温度传感器，在这种情况下，ASE-AE可以向CSE发送更改温度传感器的资源属性的请求，如将温度传感器的资源属性中的位置信息从“客厅”更改为“卧室”，然后，CSE接收到更改温度传感器的资源属性的请求之后，就可以确定对温度传感器的资源属性进行了变更。
根据本公开实施例，所述与被监控的应用实体相关联的动作资源可以是在所述被监控的应用实体完成初始注册之后创建的。
作为示例，温度传感器或空调设备在向CSE完成初始注册之后，可以创建与温度传感器或空调设备相关联的动作资源，当然，也可以在温度传感器或空调设备在向CSE完成重新注册之后，创建与温度传感器或空调设备相关联的动作资源。也就是说，物联网设备(如温度传感器或空调设备)至少向 CSE完成一次注册之后，才可以创建与物联网设备(如温度传感器或空调设备)相关联的动作资源。
根据本公开实施例，所述订阅通知可以包括以下各项中的至少一项：关于被监控的应用实体的当前动作资源失效的通知、关于与被监控的应用实体相关联的动作资源列表的通知、以及关于被监控的应用实体的动作资源重新生效的通知。
作为示例，被监控的应用实体可以是温度传感器，假设关于温度传感器设置了以下动作资源：
动作资源1：“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的空调”；
动作资源2：“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的窗户”；
动作资源3：“当温度传感器监测到客厅内环境温度小于15摄氏度时，关闭客厅内的窗户”。
作为示例，当温度传感器从客厅移到卧室时，则被通知的应用实体(如ASN-AE或中间节点(如网关)中的应用实体)可以收到关于温度传感器的当前动作资源1失效的通知。
作为示例，当温度传感器从客厅移到卧室时，则被通知的应用实体(如ASN-AE或中间节点(如网关)中的应用实体)可以收到与温度传感器相关联的动作资源2至3列表的通知。可选地，在所述通知中，可以在与动作资源对应的位置处设置让用户选择以确定相应的动作资源是继续生效还是失效的键。
作为示例，当温度传感器从客厅移到卧室后又重新将温度传感器从客卧室到客厅时，则被通知的应用实体(如ASN-AE或中间节点(如网关)中的应用实体)可以收到关于温度传感器的动作资源3重新生效的通知。
根据本公开实施例，在上述创建动作资源之后，可以将所述动作资源的激活状态属性的值设置为启用对所述动作资源的监控。
根据本公开实施例，如下表3所示，表3示出了动作(<action>)资源的属性的部分内容，其还可以包括其他的内容，这里不在赘述。
在表3中，动作资源的激活状态属性(表3中示出为ActiveStatus)的值可以在上述创建动作资源之后被CSE设置为启用对所述动作资源的监控的 值(即，被设置为TRUE)
Figure PCTCN2022073217-appb-000004
Figure PCTCN2022073217-appb-000005
表3动作资源的属性
在表3中，值“0..1”表示子资源/属性可能存在；值“1”表示应该存 在子资源/属性；用(L)后固定的属性多重性表示它是一个值列表；RW表示读写；MA表示强制公告(Mandatory Announced)，即原始资源中的属性被公告到已公告的资源，这样一个公告的属性的内容和原来属性的内容是一样的；OA可选公告(Optional Announced)，即原始资源中的属性可以根据在原始资源处公告的属性的内容向公告的资源进行公告，这样一个公告属性的内容和原来属性的内容是一样的。
作为示例，CSE在创建如“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的空调”动作资源后，可以将ActiveStatus的值设置为TRUE，这样在CSE中创建的上述动作资源就会被CSE监控，并且在主要事件被触发之后继续核验相关的依赖关系，以确定触发相关动作。例如，当温度监测到客厅内环境温度大于31摄氏度时，则CSE监控到上述动作资源中的触发条件已被满足，则执行上述动作资源中的相应动作，即开启客厅内的空调，从而使得上述动作资源得以正常实现。
根据本公开实施例，在所述向被通知的应用实体发送与所述被监控的应用实体相关联的动作资源对应的订阅通知之后还可以包括：响应于接收到所述被监控的应用实体的动作资源失效的指示，将所述动作资源的激活状态属性的值设置为禁用对所述动作资源的监控。
作为示例，CSE响应于接收到“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的空调”动作资源失效的指示，可以将ActiveStatus的值设置为FALSE，从而不对上述动作资源进行相关的监控。
作为示例，上述动作资源失效的指示可以是通过用户在相关的订阅通知的界面中选择相关的按键来获得，也可以基于物联网管理平台预定义的规则来获得。
作为示例，在相关的订阅通知的界面中动作“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的空调”后设置有表示可以选择以决定上述动作继续生效还是失效的按键。当用户选择了失效的按键后，CSE就会将ActiveStatus的值设置为FALSE，这样在主要事件被触发之后就不会继续核验相关的依赖关系，以确定触发相关动作。例如，温度监测到客厅内环境温度大于31摄氏度时，客厅内的空调就不会开启，使得上述动作资源得不能实现，即失效。
作为示例，卖方在自家客厅设置了关于空气净化器的动作，之后，卖方 把空气净化器卖给了买方，买方在自己的卧室里设置了关于空气净化器的动作，则此时物联网管理平台可以根据买卖双方的距离、接入点等信息来确定此时卖方设置的动作资源中关于这台空气净化器的动作资源失效，则卖方通过如ASN-AE或中间节点(如网关)中的应用实体不仅可以收到与这台空气净化器的动作资源失效的订阅通知，而且CSE会根据上述动作资源失效的指示，将ActiveStatus的值设置为FALSE，从而使得对对这台空气净化器不进行继续的监控。
以上结合图3和表1-3详细描述了由通用服务实体执行的订阅通知的方法。由以上内容可知，本公开提供的上述订阅通知的方法可以将订阅资源与动作触发进行紧密的结合，当被监控的应用实体的资源属性变更时，可以及时地向被通知的应用实体发送与所述被监控的应用实体相关联的动作资源对应的订阅通知，从而可以使被通知的应用实体能够及时获知于所述被监控的应用实体的相关动作资源生效还是失效，进而使相关的动作继续触发，这更好地符合了用户的实际操作实践，增强了用户的物联网体验。
由此，订阅资源与动作资源之间进行了紧密的结合。以下描述了用于经由动作资源<action>和<dependency>资源来管理物联网设备的动作触发的过程。
当用户希望响应于检测到特定的智能场景的事件而使得物联网设备执行特定动作时，就创建<action>资源。事件具有与之相关联的对象资源–该对象资源的改变导致托管CSE有条件地触发对象资源的目标动作。对象资源由<action>资源的subjectResourceID属性来标识，并且<action>资源的evalCriteria属性确定动作是否被有条件地触发。总的来说，该组合被称为事件表达式，并且事件在被触发时是主要事件。
为了处理更复杂事件，可以创建一个或多个<dependency>资源作为<action>资源的子资源。在<dependency>资源内，dependentResourceID属性标识事件依赖的资源。<dependency>资源的evalCriteria属性确定是否满足依赖条件。逻辑属性确定依赖条件对于动作触发是足够的(SUFFICIENT)还是必要的(NECCESARY)。最后，<action>资源的evalPriority属性确定在评估是否应该基于主要事件触发动作或操作时要应用的依赖条件的优先级。托管CSE将按照evalPriority优先级顺序来评估依赖条件。
以下描述了托管CSE执行管理事件监控的过程，以及事件发生时，指定 的动作和操作的条件触发，具体步骤如下。
步骤一：CSE将<action>资源创建为对象资源的子资源或资源树中的其它位置。对象资+源可以是任何资源，并且由subjectResourceID属性指示。CSE可以创建一个或多个<dependency>资源作为<action>资源的子资源。
对象资源的改变可能触发evalCriteria的评估。
步骤二：CSE确定对象资源的属性或子资源是否变更。如果变更，则CSE对对象进行更新。
步骤三：托管CSE得到更新的结果，以及评估如果更新的对象资源并且如果更新的对象资源与<action>资源的evalCriteria属性中定义的标准相匹配，则认为触发了主要事件。
步骤四：如果<action>资源的ActiveStatus属性为TRUE，则托管CSE进行执行到步骤五；如果<action>资源的ActiveStatus属性为FALSE(例如，由于对象资源的属性变更导致该动作资源失效)，则后续的触发过程不再执行。
步骤五：在步骤三中触发了主要事件之后，如果至少存在一个<action>资源的<dependency>子资源，则托管CSE按照evalPriority属性中提供的顺序或按照基于本地策略(如果属性缺失)的顺序来处理每个<dependency>子资源。
由以上内容可知，本公开提供的订阅通知的方法，在上述动作触发过程中增加了新的步骤四，即激活状态(ActiveStatus)的判断，从而将订阅过程和动作触发过程进行紧密的结合，以更好地符合用户的实际操作实践，增强了用户的物联网体验。
上述在对本公开提供的订阅通知的方法中，用到了应用实体的注册，接下来将结合图4对注册解决方案进行介绍。
图4示出了应用实体(AE)或应用程序(APP)或节点(Node)向通用服务实体(CSE)注册的流程图。
参照图4，应用实体(AE)或应用程序(APP)或节点(Node)向通用服务实体(CSE)进行注册包括以下步骤和情况。
步骤1(可选)：AE或APP或Node与注册服务商CSE安全关联建立。
步骤2：AE或APP或Node向注册服务商CSE发送创建AE资源的请求，并且该请求中包括其标识符(如App-ID，AE-ID-Stem)，即向注册服务商CSE 发送Request(CREATE<AE>)。
步骤3：注册服务商CSE通过在服务订阅配置文件(凭证ID，注册服务商CSE)中查找，或者，直接从使用过的证书(如果有)确定允许的AE-ID-Stem值和App-ID的组合。
如果在注册服务商CSE上不可用，可能需要可选地从服务订阅配置文件中检索信息。
步骤4：检查<AE>创建请求是否与步骤3中确定的允许组合一致。
以下步骤可以适用于AE(例如上述的温度计)初始注册和重新注册过程，具体如下：
首先，AE向CSE提供以’S’开头的AE标识符AE-ID-Stem(即AE指定的标识符)，然后，进行如下步骤：
步骤5：注册服务商CSE向IN-CSE发送更新或创建AE公告的请求，即发送Request(UPDATE or CREATE<AEannc>)，其中，创建AE表示要初始注册过程，更新AE表示要重新注册过程。
步骤6：IN-CSE验证“更新”或“创建”请求(包括凭证标识、注册CSE),更新或创建<AEannc>资源。
步骤7：IN-CSE向注册服务商CSE发送相应的响应，即发送Response(UPDATE or CREATE<AEannc>)。
步骤8：注册服务商CSE使用由AE提供的AE-ID-Stem来创建<AE>资源。
步骤9：注册服务商CSE向AE或APP或Node发送对创建的响应，即发送Response(CREATE<AE>)。
由此，AE(例如上述的温度传感器)可以利用上述注册过程完成初始注册。但是当AE的属性变更(例如，温度传感器从卧室移至阳台)，此时AE可能会通过重新注册的方式来向CSE告知其的属性变更，即可以通过上述注册过程来完成重新注册来向CSE告知其的属性变更。
并且，由上述重新注册过程可知，AE沿用了第一次注册的AE-ID-Stem。因此，在重新注册的过程中，即使AE的属性变化了，AE的AE-ID-Stem也没有变化。因此，即使是由于重新注册导致的AE的属性变化，CSE仍然可以利用判断重新注册的AE的AE-ID-Stem是否在订阅资源的订阅监控列表中的方式，来进一步确定是否向ASN-AE发送订阅通知，以告知ASN-AE与该重新注册的AE相关联的动作资源是否失效。
本公开实施例除了提供上述订阅通知的方法之外，还提供了一种由用于物联网的终端执行的方法，接下来将结合附图5A至图5C对此进行详细说明。
图5A示出了根据本公开实施例的由用于物联网的终端执行的方法的流程图。所述终端可以是手持设备(如手机)、平板电脑等。
参照图5A，在步骤S510，可以显示对物联网设备的动作进行设置的界面，所述界面可以包括对所述物联网设备的动作进行设置的设置按钮。
作为示例，物联网设备可以是温度传感器和空调设备。
作为示例，如图5B所示，当前显示的界面就是对温度传感器和/或空调设备的动作进行设置的界面，其中，在与温度传感器或空调设备对应的设置按钮是可以被用户点击的，从而对温度传感器或空调设备的动作进行设置。
在步骤S520，在用户点击上述设置按钮后，用于物联网的设备可以响应于所述设置按钮被触发，然后显示用于启用对所述物联网设备的属性变更进行监控的启用按钮。
作为示例，当用户点击了与温度传感器对应的设置按钮时，会弹出如图5C所示的属性变更监控界面，在该界面中，列出了可以启用属性变更监控的相关属性，例如：位置、过期时间、标签等，并且在与所示相关属性对应的位置处设置有启用按钮，用户可以选择该启用按钮。此外，当选择图5C中的最后一个启动按钮时，表示对所有的属性变更均进行监控。
在步骤S530，响应于所述启用按钮被触发，可以订阅与所述物联网设备的属性变更对应的订阅通知，其中，所述物联网设备的属性变更导致所述物联网设备的动作异常。
作为示例，当用户选择了与位置属性相对应的启用按钮后，就会对温度传感器的位置属性就行监控，也就是说，订阅了与温度传感器的位置属性变更对应的订阅通知。当温度传感器的位置属性发生变化时，就会使之前设置的温度传感器的动作异常，比如之前设置的动作不执行。
根据本公开实施例，在所述显示对物联网设备的动作资源进行设置的界面之前可以包括：显示用于创建与所述物联网设备相关联的动作的动作创建界面，所述动作创建界面包括以下各项中的至少一项：设置所述动作的内容的选择框、设置所述动作的生效条件的选择框、设置所述动作关联的物联网设备的属性的选择框。
作为示例，在显示对物联网设备的动作资源进行设置的界面之前，可以 显示用于动作创建的界面，在该界面中可以包括设置动作的内容选择框，在选择框中例如可以选择如果满足条件时开启相关设备、如果被移动时开启相关设备等；在该界面中还可以包括设置所述动作的生效条件的选择框，如每天16:00使动作生效；在该界面中还可以包括动作关联的物联网设备的属性的选择框，如选择动作关联的温度传感器的属性的选择框，在所述属性选择框中，选择温度传感器的相关属性，如位置等。
根据本公开实施例，在所述显示创建与所述物联网设备相关联的动作的界面之前可以包括：显示用于注册所述物联网设备的注册界面，所述注册界面可以包括发起对所述物联网设备进行注册的按钮。
作为示例，在注册界面中，可以发起对温度传感器进行注册，比如注册到家庭网关。
根据本公开实施例，所述订阅通知可以是由所述物联网设备的重新注册导致的所述物联网设备的属性变更而触发的。
作为示例，所述物联网设备可以是空气净化器，在所述空气净化器的重新注册导致的其属性变更的情况下，触发了所述订阅通知。
根据本公开实施例，所述订阅通知用于以下项中的至少一项：关于所述物联网设备的当前动作资源失效的通知、关于与所述物联网设备相关联的动作资源列表的通知、以及关于所述物联网设备的动作资源重新生效的通知。
作为示例，所述物联网设备可以是温度传感器，关于温度传感器设置了以下动作：
动作资源1：“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的空调设备”；
动作资源2：“当温度传感器监测到客厅内环境温度大于31摄氏度时，开启客厅内的窗户设备”；
动作资源3：“当温度传感器监测到客厅内环境温度小于15摄氏度时，关闭客厅内的窗户”。
作为示例，当温度传感器从客厅移到卧室时，则所述订阅通知可以用于关于温度传感器的当前动作资源1失效的通知。
作为示例，当温度传感器从客厅移到卧室时，则所述订阅通知可以用于与温度传感器相关联的动作资源2至3列表的通知。
作为示例，当温度传感器从客厅移到卧室后又重新将温度传感器从客卧 室到客厅时，则所述订阅通知可以用于关于温度传感器的动作资源3重新生效的通知。
以上结合图5A至图5C详细描述了由用于物联网的终端执行的方法。根据本公开提供的方法，用户可以在所述用于物联网的终端上对物联网设备的相关属性的变更进行监控，订阅对应的订阅通知，从而对所述物联网设备的属性变更进行及时监控，使相关的动作异常，符合了用户的实际操作实践，增强了用户的物联网体验。
接下来将结合图6以一个示例对上述介绍的内容进行示例性介绍。
图6示出了根据本公开实施例的通用服务实体和应用实体之间的交互图。
如图6所示，整个交互过程的参与方包括第一AE(例如，ASN-AE、手机里的应用程序)、CSE(如家庭网关)以及第二AE(例如，ADN-AE、温度计)。
在步骤S610，第一AE向CSE发送注册请求，CSE在接收所述注册请求并创建与所述第一AE对应的资源之后，在步骤S620，向所述第一AE发送注册创建响应，表示注册成功(具体注册流程可参见上述图4)。

在步骤S670，CSE创建对被监控的应用实体(如温度传感器)相关联的订阅资源，并把温度传感器的标识符添加到订阅监控列表中。
在步骤S680，第一AE向CSE发送更改第二AE(如温度传感器)的资源的属性的请求，如将温度传感器的位置从“客厅”更改为“卧室”；CSE接收到上述更改请求并处理后，在步骤S690，向第一AE发送属性变更响应，表示更改成功。
在步骤S6110，CSE在订阅监控列表中检查是否存在与温度传感器的标识符相同的标识符，若存在，则在步骤S6120，CSE向第一AE发送该订阅的通知，具体通知的内容可以参见上述结合图1A至图5C进行的相关介绍，此次 不再赘述。
在步骤S6130，第二AE(如温度传感器)向CSE发送了重新注册请求，在该请求中，所述第二AE的位置发生了变化，CSE在接收所述重新注册请求并创建与重新所述第二AE对应的资源之后，在步骤S6140，向所述第二AE发送重新注册创建响应，表示重新注册成功(具体注册流程可参见上述图4)。
在步骤S6150，CSE在订阅监控列表中检查是否存在与温度传感器的标识符相同的标识符，若存在，则在步骤S6160，CSE向第一AE发送该订阅的通知，具体通知的内容可以参见上述结合图1A至图5C进行的相关介绍，此次不再赘述。
