本申请的实施例提供一种订阅消息的处理方法、装置、计算机设备和存储介质，旨在解决由于RCD可能长时间或者周期性处于休眠状态、或无法实时处理大批量的业务请求，因此可能存在RCD接收通知消息不及时、或者遗漏通知消息的技术问题。下面将通过实施例并结合附图具体地对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。需要说明的是，本申请实施例提供的一种订阅消息的处理方法，以不同的执行主体对各实施例进行说明，其中图2和图3的执行主体为订阅设备，图4-图8的执行主体为NS设备，图9-图11的执行主体为RCD。其中，各实施例的执行主体均还可以是订阅消息的处理装置，其中该装置可以通过软件、硬件或者软硬件结合的方式实现资源更新的部分或者全部。
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面对执行主体为订阅设备的各实施例进行说明。
在一个实施例中，图2提供了一种订阅消息的处理方法，本实施例涉及的是订阅设备通过NS设备向对应的RCD发送通知消息的具体过程。如图2所示，该方法包括：
S101，订阅设备接收订阅消息；所述订阅消息中包括通知消息的发送地址和订阅资源标识。
其中，订阅消息用于RCD向其它的设备订阅需要的资源，其可以包括通知消息的发送地址和订阅资源标识，也可以包括，订阅消息发送端的设备标识、订阅消息接收端的标识、该订阅消息的操作类型等。其中通知消息的地址表示RCD订阅的资源发生变化时，订阅设备给该资源设备反馈的通知消息的地址，订阅资源标识为需要订阅的资源的身份标识，该标识用于与其他资源进行区分。在实际应用中，订阅设备接收包含了通知消息发送 地址和订阅资源标识的订阅消息，其中，订阅设备可以是接收RCD发送的订阅消息也可以是接收NS设备发送的订阅消息。其中，订阅设备接收订阅消息的方式可以是通过无线通信的方式接收，例如：WIFi、红外通信或者3G、4G、5G等，本实施例对此不做限定。
S102，所述订阅设备监控所述订阅资源标识对应的目标资源。
基于上述S101步骤中接收的订阅消息，订阅设备对该订阅消息中订阅资源标识对应的目标资源进行监控，其中，该订阅设备监控目标资源可以是监控该目标资源的状态，例如：工作状态、使用状态等，本实施例对此不做限定。需要说明的是，在本申请实施例中，每个资源都对应一个资源标识，即，订阅消息中携带的订阅资源标识对应的资源即为目标资源。其中，订阅设备中还可以建立订阅消息发送端、订阅的目标资源以及通知消息地址的维护关系表，用于订阅设备后续发送通知消息时可以进行正确发送。
S103，若所述订阅设备监控到目标资源发生变化，根据所述通知消息的发送地址向通知代理NS设备发送通知消息，以使所述NS设备向对应的RCD转发所述通知消息。
其中，通知消息用于指示RCD订阅的资源发生变化，NS设备为RCD处于休眠状态或者其他无法工作的状态时，选定的一个通知代理来帮助其接收通知消息的设备。其中，RCD为由于硬件资源的相对匮乏，导致其业务处理能力和续航能力都较差的设备，RCD在网络中可能会周期性进入睡眠状态(节省电力)、或无法实时处理大批量的业务请求。
本步骤中，在订阅设备监控的目标资源发生变化，例如目标资源的工作状态发生变化时，订阅设备发送该目标资源的工作状态发生变化的通知消息给NS设备，发送的地址为订阅消息中携带的通知消息的发送地址。在NS设备接收到该通知消息时，将该通知消息转发给对应的RCD。示例地，订阅设备发送的通知消息包括：from:3rd device；to：RCD；op：notify；payload:{target resouce}。其中，订阅设备发送通知消息给NS设备的方式以及NS设备将该通知消息转发给RCD的方式，均可以是通过无线通信的方式进行传输，例如：WIFi、红外通信或者3G、4G、5G等，本实施例对此不做限定。
本实施例提供的一种订阅消息的处理方法，订阅设备先接收包含通知消息的发送地址和订阅资源标识的订阅消息，然后监控该订阅消息中订阅资源标识对应的目标资源，并在目标资源发生变化时，向NS设备发送通知消息，以使NS设备向对应的RCD转发该通知消息，这样，在RCD长时间或者周期性处于休眠状态、或无法实时处理大批量的业务请求时，订阅设备可以将该RCD需要的消息发送给NS设备，NS设备可以在RCD工作状态时将通知消息转发给RCD，使得RCD可以及时的接收消息、不遗漏任何一条消息，大大提高了RCD获取消息的成功率。
由于在一些场景中，为了保证订阅设备中的资源被安全可靠的设备订阅，可以对各个订阅消息发送端的权限进行鉴别。因此，本申请实施例提供了一种订阅消息的处理方法，本实施例涉及的是订阅设备根据订阅消息中携带的订阅消息的发送端设备标识，对订阅消息的发送端订阅目标资源的权限进行鉴定的具体过程，如图3所示，该方法还包括：
S201，所述订阅设备根据所述订阅消息中携带的设备标识，鉴权所述订阅消息的发送端是否具有订阅所述目标资源的权限。
在本实施例中，订阅设备根据订阅消息中携带的设备标识，对该订阅消息的发送端是否具有订阅该目标资源的权限进行鉴定，其中，订阅设备对该订阅消息的发送端的权限进行鉴定的方式可以是查看是否存储了该订阅消息发送端的设备标识与目标资源之间的映射关系，如果存在，则表示该发送端具有订阅目标资源的权限，否则，则表示没有。需要说明的是，在应用本申请实施例提供的订阅消息处理方法之前，需要预先将订阅消息发送端的设备标识与目标资源之间的映射关系存储在订阅设备的数据库中，用于表示订阅消息发送端具有订阅该目标资源的权限。
S202，若所述发送端具有订阅所述目标资源的权限，则所述订阅设备存储所述订阅消息，并向所述发送端发送订阅完成通知消息。
基于上述S201步骤对订阅消息发送端权限的鉴定，若订阅设备确定该发送端具有订阅目标资源的权限，则存储该发送端发送的订阅消息，并向该发送端发送订阅完成通知消息，以通知发送端该资源订阅成功。其中，订阅设备向发送端发送通知消息的方式可以是通过WIFi、红外通信或者3G、4G、5G等无线方式，本实施例对此不做限定。
可选地，该发送端可以为RCD或所述RCD对应的NS设备。具体的，当RCD需要向订阅设备订阅资源时，可以直接向订阅设备发送订阅消息，也可以是RCD向NS设备发送订阅消息，再由NS设备将该订阅消息发送给订阅设备。
在实际应用中，当发送端为RCD时，订阅设备根据订阅消息中携带的RCD的标识，先对RCD是否具有订阅目标资源的权限进行鉴定，在确定该RCD具有权限时，存储该RCD发送的订阅消息，并向RCD发送订阅完成通知消息。同理，当发送端为NS设备时，订阅设备根据订阅消息中携带的NS设备的标识，先对NS设备是否具有订阅目标资源的权限进行鉴定，在确定该NS设备具有权限时，存储该NS设备发送的订阅消息，并向NS设备发送订阅完成通知消息，这里可以理解的是，NS设备为RCD的代理，在订阅成功后，后续NS设备接收的订阅设备发送的通知消息，NS设备会将其转发给对应的RCD。
本实施例提供的一种订阅消息的处理方法，订阅设备根据订阅消息中携带的设备的标识，先对订阅消息发送端是否具有订阅目标资源的权限进行鉴定，在确定该发送端具有权限时，存储该发送端发送的订阅消息，并向该发送端发送订阅完成通知消息。这样，只在发送端具有订阅该目标资源权限时才进行后续步骤，避免了没有访问权限的发送端订阅目标资源，提高了资源信息的安全可靠性，而且避免了订阅设备资源和时间的浪费。
考虑到订阅设备根据订阅消息中的通知消息发送地址向NS设备发送通知消息之后，需要知道该NS设备是否已经成功接收，则在一个实施例中，所述方法还包括：所述订阅设备接收所述NS设备发送的通知应答消息。具体地，订阅设备在将通知消息按照通知消息发送地址发送给NS设备之后，接收NS设备发送的通知应答消息，这样，若订阅设备接收到NS设备发送的通知应答消，则表示订阅设备发送的通知消息发送成功，大大提高了订阅设备的发送消息的成功率。
下面对执行主体为NS设备的各实施例进行说明。需要说明的是，以下各实施例中涉及部分内容在上述执行主体为订阅设备的各实施例中已经进行了描述，重复的内容将不再赘述。
在一个实施例中，图4提供了一种订阅消息的处理方法，本实施例涉及的是NS设备接收订阅设备发送的通知消息，并将该通知消息转发给RCD的具体过程。如图4所示，该方法包括：
S301，NS设备接收订阅设备发送的通知消息；所述通知消息用于指示RCD订阅的目标资源发送变化。
具体地，NS设备接收订阅设备发送的通知消息，这里通知消息用于指示RCD订阅的目标资源发生变化，例如，订阅设备监控到RCD订阅的目标资源的工作状态发生了变化，会发送通知消息给NS设备。通知消息的具体格式和发送方式可参见图2中的描述，此处不再赘述。
S302，所述NS设备将所述通知消息发送给对应的RCD。
基于上述S301步骤中，NS设备接收订阅设备发送的通知消息，NS设备将该通知消息发送给对应的RCD，其中，NS设备将该通知消息发送给对应的RCD可以是NS设备主动将该通知消息发送给RCD，也可以是接收到RCD发送的获取消息后，将对应的通知消息发送给RCD。
本实施例提供的一种订阅消息的处理方法，NS设备先接收订阅设备发送的RCD订阅的目标资源发送变化的通知消息，然后将该通知消息转发给RCD，使得在RCD长时间或者周期性处于休眠状态、或无法实时处理大批量的业务请求时，订阅设备可以将该RCD 需要的消息通过NS设备进行转发，使得RCD可以及时的接收消息、不遗漏任何一条消息，大大提高了RCD获取消息的成功率。
可选地，在NS设备接收订阅设备发送的通知消息之后，所述方法还包括：所述NS设备向所述订阅设备发送通知应答消息。本实施例中，NS设备向订阅设备发送通知应答消息，以便订阅设备确定通知消息已经发送成功，后续可以正常的发送通知消息给NS设备，进而保证了RCD获取消息的成功率，提高了通信质量。
在上述实施例的基础上，本实施例提供了一种订阅消息的处理方法，本实施例涉及的是NS设备根据RCD发送的查询消息将所述通知消息发送给对应的RCD的具体过程。如图5所示，上述步骤S302包括：
S401，所述NS设备接收所述RCD发送的查询消息；所述查询消息中包括所述RCD设备标识。
其中，NS设备接收RCD发送的查询消息，其中，查询消息表示RCD在NS设备查询是否有自己需要的通知消息，该查询消息中包括所述RCD设备标识，该设备标识表示该RCD的身份标识，该标识可以是数字、字母或者数字与字母的组合。本实施例对RCD标识不做限定。可选地，RCD可以周期性的向NS设备发送查询消息，也可以是RCD在脱离休眠模式后向NS设备发送查询消息，或者，RCD在获知到NS设备有自身所需的通知消息时，向NS设备发送查询消息。
S402，所述NS设备根据RCD设备标识与资源标识之间的对应关系，确定所述RCD设备标识对应的目标资源标识。
基于上述S401步骤中，NS设备接收RCD发送的查询消息，NS设备根据RCD设备标识与资源标识之间的对应关系，确定RCD设备标识对应的目标资源标识。需要说明的是，每个RCD设备标识与其所需要的目标资源之间建立了一一对应的关系，并存储在NS设备中，NS设备在存储的所有对应关系中查找该RCD设备标识对应的资源，确定该资源为RCD设备标识需要的目标资源。
S403，所述NS设备将携带所述目标资源标识的通知消息发送给所述RCD。
本步骤中，NS设备基于上述S402中确定的RCD设备标识需要的目标资源，确定携带该目标资源的通知消息，然后将该通知消息发送给RCD。
本实施例提供的一种订阅消息的处理方法，NS设备接收RCD发送的查询消息，根据该查询消息中的RCD标识确定目标资源的标识，并将携带该目标资源标识的通知消息发送给该RCD，这样，在收到RCD发送的查询消息之后，根据RCD设备标识与资源标识之间对应关系定位到目标资源，进而根据目标资源定位到准确的通知消息，大大保证了NS设备发送给RCD的通知消息的准确性。
上述S401步骤中“所述NS设备接收所述RCD发送的查询消息”包括了两种可实现方式，其中一种可实现方式包括：所述NS设备接收所述RCD按照预设周期发送的所述查询消息。RCD可以周期性的向NS设备发送查询消息，该预设周期可以是用户自定义设定的，本实施例对此不做限定，例如：每个10分钟，RCD发送的查询消息给NS设备，或者在特定状态下，RCD发送的查询消息给NS设备，这样，RCD在可以正常工作的状态下，主动发送查询消息给NS设备，确定可以及时的接收消息、不遗漏任何一条消息，大大提高了RCD获取消息的成功率。
在另外一种可实现方式中，若NS设备接收所述RCD发送的查询消息之前，所述NS设备广播通知消息列表；所述通知消息列表包括用于供所述RCD识别所述通知消息的识别参数；则“所述NS设备接收所述RCD发送的查询消息”包括：所述NS设备接收所述RCD查询所述通知消息列表后发送的查询消息。可选地，所述识别参数包括：目标资源标识、RCD设备标识或订阅关系识别码。
其中，供所述RCD识别通知消息的识别参数表示RCD在接收到NS设备发送的通知 消息列表时，对其中通知消息是不是自身所需资源的通知消息进行辨认的参数。该识别参数可以包括：目标资源标识、RCD设备标识或订阅关系识别码，其中，该目标资源标识和RCD设备标识在上述实施例中已经进行了解释，本实施例在此不再赘述；该订阅关系识别码表示的是RCD设备与其订阅的目标资源之间的对应关系的标识码，该标识码可以是数字、字母或者数字与字母的组合，本实施例对此不做限定。NS设备广播通知消息列表，表示NS设备将所有通知消息广播出来，以便所有的RCD可以看到列表中的消息，在该RCD看到NS设备广播通知消息列表中包含了自身所需的通知消息，则向NS设备发送包含该订阅资源标识和/或RCD标识的查询消息，这样，NS设备在收到该查询消息后，根据通知消息的标识和/或RCD标识将正确的通知消息发送给正确的RCD，大大保证了RCD获取消息的正确性。
需要说明的是，在RCD从NS设备上获取通知消息后，NS设备会同时删除该通知消息，但其会保留创建的通知消息中资源的通知地址。
在一些场景中，NS设备需要将RCD的请求消息转发给订阅设备，则在一个实施例中，本申请实施例提供了一种订阅消息的处理方法，涉及的是NS设备将接收的RCD发送的订阅消息发送给订阅设备的具体过程，如图6所示，所述方法还包括：
S501，所述NS设备接收所述RCD发送的订阅消息；所述订阅消息中包括通知消息的发送地址和订阅资源标识。
本实施例中，NS设备接收RCD发送的订阅消息，其中，该订阅消息表示RCD需要预定目标资源的状态变化的通知。其中该订阅消息包括通知消息的发送地址和订阅资源标识。其中，订阅资源标识即同上述实施例中描述的资源标识，用于区别各资源，其中该标识可以是数字、字母或者数字与字母的组合。
S502，所述NS设备将所述订阅消息发送给订阅设备。
基于上述S501步骤中，NS设备接收RCD发送的订阅消息，NS设备将订阅消息发送给订阅设备，以便订阅设备根据订阅消息中的通知消息的发送地址和订阅资源标识，将正确的订阅资源发生变化时的通知消息发送到RCD对应的NS设备中。
本实施例提供的一种订阅消息的处理方法，NS设备接收RCD发送的订阅消息，并按照订阅资源中包含的通知消息的发送地址和订阅资源标识，将订阅消息发送给订阅设备，这样，订阅设备可以根据通知消息的发送地址和订阅资源标识，在正确的订阅资源发生变化时，将通知消息发送到正确地址中，以便RCD可以及时的接收消息、不遗漏任何一条消息，大大提高了RCD获取消息的成功率。
在NS设备将订阅消息发送给订阅设备之后，RCD需要知道该订阅消息是否已经成功被订阅设备接收，则在一个实施例中，本申请实施例提供了一种订阅消息的处理方法，本实施例涉及的是NS设备接收订阅设备发送的订阅完成通知消息后，将订阅完成通知消息转发给RCD的具体过程，如图7所示，所述方法还包括：
S601，所述NS设备接收所述订阅设备发送的订阅完成通知消息；所述订阅完成通知消息用于指示所述NS设备具有订阅所述目标资源的权限。
本实施例中，NS设备接收订阅设备发送的订阅完成通知消息，其中该订阅完成通知消息表示NS设备具有订阅目标资源的权限，即，表示若该NS设备接收到订阅设备发送的订阅完成通知消息，则该NS设备具有订阅目标资源的权限，订阅成功。
S602，所述NS设备将所述订阅完成通知消息转发给对应的RCD。
基于上述S601步骤中，NS设备接收订阅设备发送的订阅完成通知消息，将该订阅完成通知消息转发给对应的RCD，以使RCD可以确定订阅成功。

基于上述S702步骤中，NS设备创建代理资源完成后，NS设备向RCD发送应答消息，该应答消息表示NS设备已经创建资源成功，其中，该应答消息中包括通知消息的发送地址，以便RCD可以根据该地址正确接收后续的通知消息。
本实施例提供的一种订阅消息的处理方法，NS设备根据RCD发送的资源创建请求，创建代理资源，并建立RCD、通知消息发送地址以及资源标识之间的关系表，然后反馈应答消息给RCD，这样，RCD可以在收到该应答消息后，根据应答消息中携带的通知消息地址和RCD、通知消息发送地址以及资源标识之间的关系表正确的接收到后续的通知消息，大大保证了RCD获取消息的正确率。
下面对执行主体为RCD的各实施例进行说明。同样，以下各实施例中涉及部分内容在上述执行主体为订阅设备和上述执行主体为NS设备的各实施例中已经进行了描述，重复的内容将不再赘述。
在一个实施例中，图9提供了一种订阅消息的处理方法，本实施例涉及的是RCD发送订阅消息，并接收该订阅消息中包括的通知消息的发送地址对应的NS设备发送的通知消息的具体过程。如图9所示，该方法包括：
S801，RCD发送订阅消息；所述订阅消息中包括通知消息的发送地址和订阅资源标识。
在本实施例中，RCD发送订阅消息，可以是发给NS设备，也可以发送给订阅设备，该订阅消息用于预定接收目标资源发生变化时的通知消息，其中发送的订阅消息包括通知消息的发送地址和订阅资源标识。
S802，所述RCD接收所述通知消息的发送地址对应的NS设备发送的通知消息；所述通知消息用于指示所述订阅资源标识对应的目标资源发送变化。
基于上述S801步骤中RCD发送的订阅消息，RCD接收NS设备发送的通知消息，其中，该通知消息表示RCD订阅的资源发生了变化后，订阅设备发送的通知消息。需要说 明的是无论RCD发送订阅消息给NS设备，还是订阅设备，订阅设备在发送通知消息的时候都是先发给NS设备，然后NS设备再发送给RCD。
本实施例提供的一种订阅消息的处理方法，RCD先发送订阅消息给NS设备(NS设备转发给订阅设备)或者订阅设备后，订阅设备会在RCD订阅的资源发生了变化后，发送通知消息给NS设备，然后RCD接收NS设备发送的通知消息，这样，经过NS设备在中间的转发，可以保证RCD可以及时的接收消息、不遗漏任何一条消息，大大提高了RCD获取消息的成功率。
在上述实施例的基础上，所述RCD发送订阅消息，包括：所述RCD向所述NS设备发送所述订阅消息，以使所述NS设备将所述订阅消息转发给订阅设备；或者，所述RCD向所述订阅设备发送所述订阅消息。其中，RCD发送订阅消息可以是RCD向NS设备发送订阅消息，NS设备会将该订阅消息转发给订阅设备，或者，RCD发送订阅消息给订阅设备，这样，订阅设备在接收到该订阅消息后，会将后续的通知消息发送给NS设备，以便NS设备转发给RCD，保证RCD可以及时的接收消息、不遗漏任何一条消息，大大提高了RCD获取消息的成功率。
在一个实施例中，在RCD接收通知消息的发送地址对应NS设备发送的通知消息之前，若所述RCD向所述NS设备发送查询消息；所述查询消息中包括RCD标识。则所述RCD接收所述通知消息的发送地址对应NS设备发送的通知消息，包括：所述RCD接收所述NS设备根据所述查询消息发送的所述通知消息。其中，RCD向NS设备发送查询消息，表示该RCD需要在NS设备中查询是否有需要的通知消息，其中，该查询消息包括RCD标识，然后NS设备在接收到RCD发送的查询消息后，发送通知消息给该RCD，这样，提高了RCD获取通知消息的时机的灵活性，大大保证了RCD获取消息的成功率。
上述实施例中的所述RCD向所述NS设备发送查询消息，包括：所述RCD按照预设周期向所述NS设备发送所述查询消息；或者，所述RCD查询所述NS设备广播的通知消息列表，若所述通知消息列表中指示了所述RCD需要的通知消息，则向所述NS设备发送所述查询消息；所述通知消息列表包括用于供所述RCD识别所述通知消息的识别参数。可选地，所述识别参数包括：目标资源标识、RCD设备标识或订阅关系识别码。其中，RCD发送的查询消息可以是RCD按照预设周期进行发送的，该预设周期可以是用户自定义设定的，本实施例对此不做限定，例如：每个10分钟，RCD发送的查询消息给NS设备，或者在特定状态下，RCD发送的查询消息给NS设备，这样，RCD在可以正常工作的状态下，主动发送查询消息给NS设备，确定可以及时的接收消息、不遗漏任何一条消息，大大提高了RCD获取消息的成功率。另外，RCD发送的查询消息还可以是RCD查询所述NS设备广播的通知消息列表，若所述通知消息列表中指示了所述RCD需要的通知消息，则向所述NS设备发送所述查询消息，其中，所述通知消息列表包括了用于供所述RCD识别所述通知消息的识别参数，该识别参数可以包括：目标资源标识、RCD设备标识或订阅关系识别码等。其中，NS设备广播通知消息列表，表示NS设备将所有通知消息广播出来，以便所有的RCD可以看到列表中的消息，在该RCD看到NS设备广播通知消息列表中包含了自己所需的通知消息，则向NS设备发送包含该通知消息的标识和RCD标识的查询消息，这样，NS设备在收到该查询消息后，根据通知消息中携带的资源标识和RCD标识将正确的通知消息发送给正确的RCD，大大保证了RCD获取消息的正确性。
在RCD接收NS设备发送的通知消息之前，RCD会先接收订阅完成通知消息，已确保该RCD具有订阅目标资源的权限。在一个实施例中，所述方法还包括：所述RCD接收订阅完成通知消息；所述订阅完成通知消息用于指示RCD或所述RCD对应的NS设备具有订阅所述目标资源的权限。其中，RCD接收订阅完成通知消息，若RCD发送的订阅消息给NS设备，RCD接收的是NS设备发送的订阅完成通知消息，若RCD发送的订阅消息给订阅设备，则RCD接收的是订阅设备发送的订阅完成通知消息，这样，RCD根据接收 的订阅完成通知消息，确定了该RCD或者其对应的NS设备具有订阅目标资源的权限，进而保证了RCD获取消息的成功率。
由于RCD可能处于不能正常接收消息的状态，所以需要选定一个NS设备来帮助其接收通知消息，即需要寻找有RCD需要的资源的设备来充当代理设备，在一个实施例中，本申请实施例提供了一种订阅消息的处理方法，本实施例涉及的是RCD向NS设备发送资源创建请求，并接收NS设备发送的第一应答消息的具体过程，如图10所示，所述方法还包括：
S901，所述RCD向NS设备发送资源创建请求；所述资源创建请求用于请求在RCD确定的NS设备上创建代理资源。
其中，创建代理资源表示RCD需要的资源的类型。RCD发送的资源创建请求用于请求在RCD确定的NS设备上创建代理资源，即，RCD发送的NS设备为RCD选定的代理设备，并请求该代理设备(NS设备)创建代理资源。
S902，所述RCD接收所述NS设备发送的第一应答消息；所述第一应答消息包括通知消息的发送地址。
基于上述SS901步骤中RCD向NS设备发送资源创建请求，NS设备根据该请求创建的资源类型后，会发送第一应答消息给RCD。其中，该第一应答消息表示NS设备已经创建资源成功。其中该第一应答消息包括了通知消息的发送地址，以便RCD可以根据该地址正确接收后续的通知消息。
本实施例提供的一种订阅消息的处理方法，RCD向NS设备发送资源创建请求，并接收NS设备创建资源请求成功后的第一应答消息，这样，RCD在收到该第一应答消息后，根据第一应答消息中携带的通知消息地址正确的接收到后续的通知消息，大大保证了RCD获取消息的正确率。
对于RCD选择代理设备的过程，本申请实施例提供了一种订阅消息的处理方法，其涉及的是RCD确定目标NS设备的具体过程，如图11所示，所述方法还包括：
S1001，所述RCD发送广播消息；所述广播消息包括代理资源类型标识。
本实施例中，代理资源类型标识表示的是RCD需要的资源的类型的身份标识，其可以是数字、字母或者数字与字母的组合。如图11.1所示，RCD发送广播消息，该广播消息表示RCD需要寻找一个具有RCD需要的资源的NS设备，该广播消息包括代理资源类型标识。其中，该广播消息可供多个NS设备接收。
S1002，所述RCD接收多个NS设备根据所述广播消息发送的第二应答消息。
本步骤中，如上图11.1所示，接收到RCD的发送广播消息的多个NS设备，会发送第二应答消息给RCD，即，RCD接收多个NS设备根据广播消息发送的第二应答消息。其中，第二应答消息表示该多个NS设备均符合成为该RCD的代理设备的条件。其中，各NS设备发送第二应答消息给RCD使用单播方式。
S1003，所述RCD根据所述第二应答消息，从所述多个NS设备中确定目标NS设备。
基于上述S1002步骤中，RCD接收到的多个NS设备发送的第二应答消息，继续参见图11.1，RCD从多个NS设备中确定目标NS设备。可选地，RCD从多个NS设备中确定目标NS设备的一种可实现方式包括：所述RCD根据各所述第二应答消息中携带的NS设备的优先级，将优先级最高的NS设备确定为所述目标NS设备。其中，NS设备的优先级表示各NS设备的作为目标NS设备的优选度，优先级越高的NS设备越适合作为目标NS设备。在各NS设备发送的第二应答消息中，会携带各自的优先级，则RCD根据各第二应答消息中携带的NS设备的优先级，将优先级最高的NS设备确定为所述目标NS设备。
示例地，如图11.2所示，本申请实施例提供的一种订阅消息的处理方法，其整体过程可以是：RCD发送资源创建请求给NS设备，NS设备收到该资源创建请求后，发送第二应答消息给RCD，然后RCD发送订阅请求给NS设备(NS设备再将该订阅请求发送给订 阅设备)或者订阅设备，订阅设备接收到该订阅请求后对RCD或者NS设备进行是否具有订阅资源的权限鉴定，订阅设备确认RCD或者NS设备具有订阅该资源的权限后，监控该资源的状态，在该资源状态发生变化时，发送通知消息给NS设备，NS设备接收到该通知消息后存储该消息，并将该通知消息发送给RCD，其中NS设备将该通知消息发送给RCD的方式有两种：方式一：RCD给NS设备周期性发送通知消息查询，NS设备接收到该RCD发送的查询消息，找到该消息发送给RCD；方式二：NS设备周期性广播其上所存储的所有通知消息的列表，RCD接收到该广播消息后在通知消息列表上查看是否有需要的通知消息，若有，RCD发送获取该通知消息的请求给NS设备，NS设备收到该请求后，将对应的通知消息发送给RCD。
本实施例提供的一种订阅消息的处理方法，RCD接收各NS设备根据广播消息发送的第二应答消息，并根据第二应答消息中携带的各NS设备的优先级，将优先级最高的NS设备确定为所述目标NS设备，这样，最后选择的目标NS设备由于优先级最高，为RCD代理设备的最优选择，大大增加了RCD获取消息的成功率和准确率。
