具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白，下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
如图1所示，为设置BDT传输策略流程，包括如下步骤：
步骤101，业务能力服务器(SCS，Services Capability Server)/应用服务器(AS，Application Server)向业务能力开放功能(SCEF，Service Capability Exposure Function)发送BDT请求；
步骤102，SCEF对请求进行授权认证；
步骤103，SCEF与策略与计费规则功能(PCRF，Policy and Charging Rules Function)协商未来的BDT过程，触发PCRF执行PCC过程，提供可能的BDT传输策略给SCEF；
步骤104，SCEF向SCS/AS返回BDT响应，响应包括可能的BDT传输策略；
步骤105，如果有不止一个可能的BDT传输策略，SCS/AS选择其中一个并通知SCEF；
步骤106，SCEF确认SCS/AS所选BDT传输策略；
步骤107，SCEF继续与PCRF协商BDT传输策略，并在用户属性存储器(SPR，Subscription Profile Repository)中存储SCS/AS选择的BDT传输策略；
步骤108，SCS/AS在后来的某一时间点，通知PCRF，PCRF、策略和计费执行功能(PCEF，Policy and Charging Enforcement Function)、SPR执行PCC过程，对节点实施BDT传输策略。
其中，步骤108是业务/应用实体在设定的时间窗内通知3GPP网络加载使用配置的策略，基于资源架构方式的外部系统的业务/应用实体如何请求3GPP网络加载并执行配置的BDT传输策略，对其传输过程进行监控，并不属于3GPP的范围，现有技术中没有得到解决。
本发明实施例是在基于oneM2M标准组织的基于资源的oneM2M系统架构中实现，物联网功能实体(包括AE/CSE)通过IN-CSE(oneM2M的物联网平台)发起基于BDT传输策略的底层网络传输。
实施例一
如图2所示，本发明实施例一的执行传输策略的方法包括如下步骤：
步骤201，物联网功能实体根据在底层网络中已配置的BDT传输策略，通过IN-CSE通知所述底层网络使用所述BDT传输策略监控的目标节点，以使所述底层网络使用所述BDT传输策略监控目标节点的数据传输；
其中，所述物联网功能实体为物联网AE或物联网CSE。
物联网功能实体为配置在底层网络中BDT传输策略的发起者，物联网功能实体通过在IN-CSE中创建BDT资源发起并完成BDT传输策略的配置，物联网功能实体通过IN-CSE提供的标准接口查询BDT资源确定其已配置BDT传输策略并获知其所配置的BDT传输策略等内容。
本发明实施例提供一种统一的操作方式，更有利于将3GPP网络加载并执行配置的BDT传输策略的能力开放给各种的外部系统功能实体，在外部功能实体不支持3GPP标准接口的情况下，通过IN-CSE对3GPP网络进行操作。在本发明实施例中，通过IN-CSE通知所述3GPP底层网络使用所述BDT传输策略传输数据，可以使得3GPP底层网络可以知晓基于资源架构 方式的外部系统的业务/应用实体希望3GPP底层网络使用所述BDT传输策略监控目标节点的传输数据，从而填补了现有技术的空白。
所述底层网络可以包括PCEF、SPR和PCRF。所述目标节点可以是应用专用节点(AND，Application Dedicated Node)或应用业务节点(ASN，Application Service Node)或中间节点(MN，Middle Node)。
在一些实施例中，所述物联网功能实体通过发送携带使用BDT传输策略的参数的消息给IN-CSE，以使所述IN-CSE获知物联网功能实体请求底层网络使用所述BDT传输策略，进而通知所述底层网络使用所述BDT传输策略监控的目标节点。
在一些实施例中，所述物联网功能实体向所述IN-CSE发送创建或更新BDT资源的BDTList(BDT列表)属性的请求消息，进而通知所述底层网络使用所述BDT传输策略监控的目标节点，即指示所述物联网功能实体与目标节点进行数据交互时，所述底层网络执行BDT传输策略。
其中，所述创建或更新BDT资源的BDTList属性指示使用所述BDT传输策略监控的目标节点标识。
其中，物联网功能实体向所述IN-CSE发送创建或更新BDT资源的BDTList属性的请求消息，请求消息包含在创建BDT资源的消息中，或者请求消息是在已存在的BDT资源中创建BDTList属性，或者请求消息是更新已存在的BDT资源中BDTList属性。
上述两种方案基于资源方式对资源的创建或更新，以及在对资源的操作消息中携带参数，简化了外部系统的业务/应用实体对使用3GPP底层网络能力的操作，提高了操作的效率。
实施例二
如图3所示，本发明实施例二的执行传输策略的方法包括如下步骤：
步骤301，IN-CSE接收物联网功能实体发送的消息，所述消息用于通知底层网络使用所述BDT传输策略监控目标节点的数据传输，所述物联网功能实体为物联网AE或物联网CSE；
步骤302，所述IN-CSE获知使用所述BDT传输策略监控的目标节点，向底层网络传输BDT参数以触发PCC过程，以使所述底层网络在所述物联网功能实体与目标节点进行数据交互时执行BDT传输策略。其中，IN-CSE根据底层网络提供的标准接口向底层网络传输BDT参数。
本发明实施例提供一种统一的操作方式，更有利于将3GPP网络加载并执行配置的BDT传输策略的能力开放给各种的外部系统功能实体，在外部功能实体不支持3GPP标准接口的情况下，通过IN-CSE对3GPP网络进行操作。在本发明实施例中，通过IN-CSE通知所述3GPP底层网络使用所述BDT传输策略传输数据，可以使得3GPP底层网络可以知晓基于资源架构方式的外部系统的业务/应用实体希望3GPP底层网络使用所述BDT传输策略监控目标节点的传输数据，从而填补了现有技术的空白。
在一些实施例中，所述物联网功能实体发送的消息中携带有使用BDT传输策略的参数，所述IN-CSE根据所述使用BDT传输策略的参数获知使用所述BDT传输策略监控的目标节点。
其中，BDT传输策略使用的目标节点为发送消息中接收方。
在一些实施例中，所述物联网功能实体发送的消息为创建或更新相关的BDT资源的BDTList属性的请求消息，所述IN-CSE根据所述请求消息，获知使用所述BDT传输策略监控的目标节点，并相应地创建或更新所述BDT资源的BDTList属性。
其中，BDTList属性表示目标节点的标识。
所述IN-CSE向底层网络传输的BDT参数可包括以下参数中的一种或多种组合：所述物联网功能实体传输数据的目标节点的标识或地址、标识BDT传输策略的参考标识、所述物联网功能实体标识。
其中，标识BDT传输策略的参考标识存储在BDT资源中，IN-CSE根据创建或更新的BDTList属性所在的BDT资源，获取标识BDT传输策略的参考标识。
其中，目标节点标识或地址是请求消息中BDT资源的BDTList属性的值，或者，IN-CSE通过BDT资源的BDTList属性的值映射到目标节点的 IP地址或其他标识。
上述两种方案基于资源方式对资源的创建或更新，以及在对资源的操作消息中携带参数，IN-CSE可以根据接收到的消息进行相应操作，提高了操作的效率。
如图4所示，为本发明应用实例的基于oneM2M系统与3GPP网络进行交互，通过对oneM2M系统中创建或更新BDT资源BDTList属性，实现AE/CSE与ADN/ASN/MN之间的BDT传输的示意图。
AE/CSE在IN-CSE上创建了BDT资源，即已完成了在3GPP中的BDT传输策略的配置，AE/CSE请求3GPP对ADN/ASN/MN节点采用BDT传输策略。在创建BDT资源的同时可创建BDTList属性，那么AE/CSE直接进行步骤402。
步骤401，AE/CSE按照oneM2M标准的消息格式向IN-CSE发送创建或更新BDT资源的BDTList属性的请求消息，表示了AE/CSE希望3GPP网络使用BDT传输策略进行传输数据的目标节点标识；
步骤402，IN-CSE接收到创建或更新BDT资源的BDTList属性的请求消息，鉴权AE/CSE有权限创建或更新BDT资源的BDTList属性，根据请求消息所带的信息，获知是请求在BDT资源下创建新的BDTList属性或更新现有BDTList属性的值，BDTList属性值为AE/CSE希望3GPP网络使用BDT传输策略的目标节点(ADN/ASN/MN)的标识，标识可以是节点URL、外部网络标识、组资源的标识等；即AE/CSE希望在与目标节点进行数据交互时，3GPP网络对目标节点执行BDT传输策略。
步骤403，IN-CSE向SCEF发送消息，该消息用于请求3GPP的PCC过程，请求3GPP对于AE/CSE与ADN/ASN/MN之间的数据交互执行BDT传输策略，消息包含发起者AE/CSE的标识、AE/CSE已配置BDT传输策略的referenceID、目标节点(ADN/ASN/MN)IP地址等；
其中，SCEF可以由运营商部署在底层网络中，也可以由第三方部署在底层网络之外。
步骤404，SECF通过3GPP定义的Rx的接口将业务信息传送给3GPP的相关网元，触发PCC过程，创建相关的会话，绑定相关联的会话及IP-CAN承载，相关3GPP网元将加载referenceID对应的BDT传输策略，用于后续在AE/CSE与ADN/ASN/MN数据交互中执行BDT传输策略。
步骤405，底层网络完成PCC过程，将BDT传输策略提供给配置为BDT传输策略控制的3GPP网元后，SCEF返回成功消息给IN-CSE，表示3GPP网络对AE/CSE与ADN/ASN/MN的数据交互采用BDT传输策略。
步骤406，IN-CSE完成请求创建或更新BDT资源的BDTList属性，返回资源创建或更新成功消息。
步骤407，AE/CSE按照oneM2M定义的接口及消息流程，向ADN/ASN/MN发送业务数据，3GPP网关会根据之前已经加载的BDT传输策略进行相关的数据传输监控。
如图5所示，为本发明应用实例的基于oneM2M系统与3GPP网络进行交互，通过oneM2M系统对其消息进行解析，自动触发请求3GPP网络加载BDT传输策略，使3GPP网络对AE/CSE与ADN/ASN/MN之间数据传输采用BDT传输策略的示意图。
AE/CSE在IN-CSE已创建BDT资源，即已完成了在3GPP中的BDT传输策略的配置，当满足BDT传输策略中的时间窗时，AE/CSE请求3GPP网络对AE/CSE与ADN/ASN/MN节点的数据传输采用BDT传输策略。
步骤501，AE/CSE向IN-CSE发送操作远程ADN/ASN/MN的请求消息，消息中除了oneM2M已定义的消息参数，新增BDT参数扩展现有消息参数，表示希望3GPP网络对AE/CSE与ADN/ASN/MN的数据交互采用BDT传输策略。
步骤502，IN-CSE接收步骤501发送的消息，获知部分消息中参数的内容，消息的发起者(from)为AE/CSE，消息的目的地(to)为ADN/ASN/MN，消息采用BDT传输策略进行传输，IN-CSE根据消息的发起者获知并确认该发起者已经配置相关的BDT传输策略；如果没有配置BDT传输策略， IN-CSE将拒绝发送给消息，返回错误给AE/CSE。
步骤503，IN-CSE向SCEF发送消息，该消息用于请求3GPP的PCC过程，请求3GPP对于AE/CSE与ADN/ASN/MN之间的数据交互执行BDT传输策略，消息包含发起者AE/CSE的标识、AE/CSE已配置BDT传输策略的referenceID、目标节点(ADN/ASN/MN)的IP地址等；
步骤504，SECF通过3GPP定义的Rx的接口将业务信息传送给3GPP的相关网元，触发PCC过程，创建相关的会话，绑定相关联的会话及IP-CAN承载，相关3GPP网元将加载referenceID对应的BDT传输策略，用于后续在AE/CSE与ADN/ASN/MN数据交互中执行BDT传输策略。
步骤505，底层网络完成PCC过程，将BDT传输策略提供给配置为BDT传输策略控制的3GPP网元后，SCEF返回成功消息给IN-CSE，表示3GPP网络对AE/CSE与ADN/ASN/MN的数据交互采用BDT传输策略。
步骤506，IN-CSE按照oneM2M定义的接口及消息流程，向ADN/ASN/MN发送AE/CSE发送的数据，3GPP网关会根据之前已经加载的BDT传输策略进行相关的数据传输监控。

上述两种方案基于资源方式对资源的创建或更新，以及在对资源的操作消息中携带参数，简化了外部系统的业务/应用实体对使用3GPP底层网络能力的操作，提高了操作的效率。
需要说明的是：通知模块60、第一通知模块61及第二通知模块可由所述执行传输策略的装置中的处理器结合通信接口实现。当然，处理器需要运行存储在存储器的计算机程序，以执行上述物联网功能实体侧的方法。
