Description

机器通信系统中订阅通知的方法和实体 技术领域
本发明实施例涉及通信领域，并且更具体地，涉及一种机器通信系统中订阅通知的方法和实体。
背景技术
机器通信(英文：Machine-to-Machine Communications，简称：M2M)是一种以机器智能交互为核心的、网络化的应用与服务。通过在机器内部嵌入无线或有线通信模块以及应用处理逻辑，机器通信可以实现无需人工干预的数据通信，以满足用户对监控、指挥调度、数据采集和测量等方面的信息化需求。
机器通信的统一机器到机器(英文：one Machine to Machine，简称：oneM2M)标准组织的总体目标是创造M2M通信的业务层的开放标准，以促进建立一个集成各种设备和服务的未来网络，使M2M业务可互操作，也使得M2M应用可以共享基础业务并独立于网络实现。
目前M2M通信可以基于有线方式和无线方式。无线方式包括蜂窝网和短距，其中3GPP蜂窝网是广泛使用的一种无线方式。在oneM2M中，一个实体可以为其它几个实体订阅通知，如向天气预报平台为其它几个实体订阅天气预报。然而，由于通知的接收端(其它几个实体)不是订阅发起方，它们不能对通知对应的资源进行修改。

具体实施方式
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的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创 造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
图1示出了根据本发明实施例的统一机器到机器系统的示意性框架图。如图1所示，该oneM2M系统分为应用层、公共服务层以及网络服务层。其中，应用层由应用实体(Application Entity，简称为“AE”)管理负责应用的有关操作与存储，应用层中包含的是实例化的端到端oneM2M解决方案。公共服务层由公共服务实体(Common Services Entity，简称为“CSE”)管理负责汇聚应用层信息形成资源池，同时协调底层网络传输，是oneM2M中的核心层起到平台的作用，公共服务层包括一系列实例化的公共服务功能。网络层由网络服务实体(Network Services Entity，简称为“NSE”)管理负责底层网络传输，并向公共服务层提供底层网络可以提供的能力。
该oneM2M体系下层与层间的参考点(即接口)有3种，其中，Mca：AE与CSE之间的接口，负责AE到CSE或CSE到AE间的通信；Mcc/Mcc’：两个CSE间的接口，负责CSE间的通信；Mcn：CSE与NSE之间的接口，负责CSE到NSE或NSE到CSE间的通信。还有一个Mch参考点(图中并未画出)，是oneM2M系统与计费系统间的接口。
oneM2M系统构架主要分为两个域：基础设施域(Infrastructure Domain，简称为“IN”)以及场域(Field Domain)，其中场域包括中间节点(Middle Node，简称为“MN”)、应用服务节点(Application Service Node，简称为“ASN”)以及应用专用节点(Application Dedicated Node，简称为“AND”)，基础设施域包括公共节点。其中除ADN节点只包含AE外其他节点都包含CSE。
应理解，在本发明实施例中，该oneM2M系统中所有的实体，比如AE和CSE的信息以及数据信息等都可以以资源来表示。资源结构则详细定义了资源的表示方式，同时定义了获取这些资源的方式。这些资源都是独立可寻址的。订阅端实体(originator)可以为接收端实体(notification receiver)向服务端实体(hosting CSE)订阅资源或子资源改变的通知。例如，订阅端实体向服务端实体发送订阅创建请求，该订阅创建请求中携带服务端实体下的资源或子资源的标识地址、接收端实体的标识(notificationURI)、通知的内容和类型(notificationContentType)以及触发通知的条件(eventNotificationCriteria)等。接收端实体根据订阅创建请求，在本地创建订阅子资源。本发明实施例提供了一种订阅资源的方法和实体，能够提高前 述订阅过程中订阅修改的灵活性。
还应理解，在本发明实施例中，创建资源可以认为是创建不包括属性的资源，也可以认为是创建包括属性的资源，更新资源可以认为是在该资源下创建一个属性，也可以认为是更新该资源下的一个属性的属性值，还可以是删除该资源下的一个属性，并且，在本发明实施例中，“创建”属性和“更新”属性经常可以互换使用，“存储”和“创建”乃至“更新”也经常可以互换使用，资源下的属性、资源的属性以及资源包括的属性表示的是同一个含义，资源或属性可以指代已经被创建(或存储)的信息，也可以指代已经被确定但是尚未被创建(或存储)的信息，本发明对此并不限定。
本发明中的标识为实体的标识或地址标识，在本发明不做限定。
图2是本发明一个实施例的机器通信系统中订阅通知的方法的示意性流程图。图2所示的方法可以由服务端实体(Hosting CSE)执行。该方法包括：
201，服务端实体接收接收端实体发送的通知取消指示。
例如，在订阅端实体(AE或CSE)为接收端实体订阅了通知的场景下，若是接收端实体(AE或CSE)不想再接收到通知时，可以主动向服务端实体发送通知取消指示。具体地，发起通知取消指示的时机可以是在接收通知的过程中，或者是在接收到通知之前，本发明实施例对此不做限定。另外可选的还可以携带接收端实体的标识或地址。
202，当接收端实体有权限时，服务端实体根据通知取消指示修改资源属性，并停止向接收端实体发送通知，资源属性通知统一资源标识符(notificationURI)。
例如，服务端可以先确定接收端实体是否有权限对资源属性进行修改。如果接收端实体有权限，服务端实体可以根据通知取消指示修改该接收端实体对应的资源属性。其中，资源属性包括接收端标识(notificationURI)。
203，服务端实体向订阅端实体发送订阅修改通知消息，订阅修改通知消息用于向订阅端实体通知服务端实体对资源属性的修改。
例如，在服务端实体完成对资源属性的修改时，可以通知订阅端实体自己对接收端实体的资源属性的具体修改内容。这样，订阅端实体可以根据修改内容调整缴费等。应理解，订阅修改消息应该包括接收端实体的标识(notification receiver ID)，另一种可选实现方式是订阅修改消息中包含修改后的资源属性包括接收端标识(notificationURI)，这样订阅端实体可以获知 是哪个接收端实体对订阅资源做了修改。
另外，订阅修改消息还可以携带接收端实体的标识及订阅参考标识(subscriptionreference)。订阅参考标识指示出订阅资源，这样订阅端实体在有订阅了多个资源场景下，就可以知道是对于哪个订阅资源的请求。
其中，订阅端实体与接收端实体为机器通信系统中两个不同的实体。订阅端实体为通知的订阅发起方，例如，订阅端实体为请求服务端实体创建订阅资源的一方。接收端实体为通知的接收方，且不是通知的订阅发起方，例如为满足订阅资源中事件通知规则(event notification criteria)属性时所产生的通知消息的接收方。
基于上述技术方案，在具有权限时，接收端实体可以向服务端实体发起对资源属性的修改。接着，服务端实体根据通知取消指示对资源属性进行修改，并向订阅端实体通知具体的修改内容。这样，本发明实施例提供了一种接收端实体修改订阅资源的方法，提高了订阅修改的灵活性，同时提升了用户体验。
可选地，作为一个实施例，根据通知取消指示修改资源属性时，服务端实体根据通知取消指示，删除通知统一资源标识符中的接收端实体的标识。
例如，服务端实体接收到接收端实体发送的订阅取消指示(stop receiving notification，或notification cancellation)时，将通知统一资源标识符中的接收端实体的标识(URI)删除。同时，停止向接收端实体发送通知消息。
可选地，作为另一实施例，接收接收端实体发送的通知取消指示时，接收接收端实体发送的更新消息，更新消息携带通知取消指示。或者，服务端实体接收接收端实体发送的通知响应消息，该通知响应为事件规则满足时服务端实体产生的通知请求时通知响应，通知响应消息携带通知取消指示。或者，服务端实体接收接收端实体产生的通知请求消息，通知请求消息携带通知取消指示。
例如，接收端实体可以向服务端实体发送更新消息(update request)，更新消息携带通知取消指示。或者，接收端实体在对服务端实体的通知请求(notify request)的通知响应消息(notify response)中携带通知取消指示。或者，接收端实体可以向服务端实体发送通知请求(notify request)。
图3是本发明另一实施例的机器通信系统中订阅通知的方法的示意性流程图。图3所示的方法可以由服务端实体(hosting CSE)执行。该方法包括：
301，服务端实体接收接收端实体发送的通知取消指示。
例如，在订阅端实体(AE或CSE)为接收端实体订阅了通知的场景下，若是接收端实体(AE或CSE)不想再接收到通知时，可以主动向服务端实体发送通知取消指示。具体地，发起通知取消指示的时机可以是在接收通知的过程中，或者是在接收到通知之前，本发明实施例对此不做限定。
302，当接收端实体没有权限时，服务端实体向订阅端实体发送通知取消指示。
例如，服务端实体可以先确定接收端实体是否有权限对资源属性进行修改。如果接收端实体没有权限，服务端实体可以先向订阅端实体发送该通知取消指示。具体地，可以通过notify request消息携带该通知取消指示。
303，服务端实体接收订阅端实体根据通知取消指示发送的更新请求消息。
另外，更新请求消息还可以携带接收端实体的标识及订阅参考标识(subscriptionreference)。订阅参考标识指示出订阅资源，这样订阅端实体在有订阅了多个资源场景下，就可以知道是对于哪个订阅资源的请求。
304，服务端实体根据更新请求消息修改资源属性，并停止向接收端实体发送通知，资源属性包括通知统一资源标识符(notificationURI)。
需要说明的是订阅端实体接收到服务端实体通知取消指示后，确定是否执行303和304。
