具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的范例；相反，提供这些实施方式使得本公开将更加全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施方式中。在下面的描述中，提供许多具体细节从而给出对本公开的实施方式的充分理解。然而，本领域技术人员将意识到，可以实践本公开的技术方案而省略所述特定细节中的一个或更多，或者可以采用其它的方法、组元、装置、步骤等。在其它情况下，不详细示出或描述公知技术方案以避免喧宾夺主而使得本公开的各方面变得模糊。
此外，附图仅为本公开的示意性图解，并非一定是按比例绘制。图中相同的附图标记表示相同或类似的部分，因而将省略对它们的重复描述。附图中所示的一些方框图是功能实体，不一定必须与物理或逻辑上独立的实体相对应。可以采用软件形式来实现这些功能实体，或在一个或多个硬件模块或集成电路中实现这些功能实体，或在不同网络和/或处理器装置和/或微控制器装置中实现这些功能实体。
物联网系统是信息的产生方和信息的消费方之间的桥梁，其具体的通信过程可以包括：首先，产生方可以不断的将信息发送给物联网系统；其次，物联网系统可以对接收到的产生方产生的信息进行存储；最后，消费方可以不断从物联网系统获取信息进行消费。
进一步的，对物联网协议规定的实体进行进一步的解释以及说明。该协议规定了 两类实体：应用实体(AE，Application Entity)和通用服务实体(CSE，Common Service Entity)；其中，一个实体可以向另外一个实体进行注册；例如，AE可以向CSE注册，CSE也可以向CSE注册，注册成功后在CSE上创建资源(AE或CSE)。AE可以通过CRUDN(创建、更新、获取、删除和通知)等操作对CSE上的资源进行操作，如通过UPDATE操作请求更新AE资源下的容器内容。
在上述物联网架构下，设备和平台相关的功能通过资源进行标识。其中，<AE>资源可以用来标识物理设备内的应用逻辑，<node>可以用来标识物理设备的相关信息，<container>可以用来充当容器并存放具体的内容信息，<group>资源可以将资源组合起来进行管理。
该物联网定义的订阅通知机制可以如下步骤：首先，AE向CSE发送订阅请求，请求中可以包括订阅的事件类型；其次，当CSE产生订阅的事件类型时，则产生事件，CSE可以通过通知请求发送给AE；然后，AE接收到该通知请求时，可以将接收到通知请求的响应信息反馈至CSE。
本示例实施方式首先提供了一种基于优先级的资源处理方法。参考图1所示，该基于优先级的资源处理方法可以包括以下步骤：
步骤S110.计算第一资源的第一优先级以及第二资源的第二优先级。
步骤S120.判断所述第一资源的第一优先级是否大于第二资源的第二优先级。
步骤S130.在判断所述第一优先级大于所述第二优先级时，执行所述第一资源对应的第一操作请求。
上述基于优先级的资源处理方法中，一方面，通过设置优先级，当接收到多个操作请求时，先处理优先级较高的操作请求，避免了由于操作请求数量过多造成的在响应操作请求的同时引起混淆的问题，同时减少了系统的负担；另一方面，通过先执行优先级较高的操作请求，提高了优先级较高的操作请求的执行速度，提升了系统的服务质量同时提升了用户体验。
下面，将对本示例实施方式中上述基于优先级的资源处理方法中的各步骤进行详细的解释以及说明。
在步骤S110中，计算第一资源的第一优先级以及第二资源的第二优先级。
首先，对资源进行解释以及说明。在现有的物联网规范中，任何设备、网关或业务平台以及注册在它们上面的应用，都可以被抽象为资源并且具有唯一的资源标识，即URI(UniformResource Identifier)，根据资源标识可以唯一定位资源。对被访问资源请求的处理可以包括获取Retrieve、创建Create、更新Update、删除Delete以及Notify等。需要说明的是，被访问资源所属的设备上可能同时存在多个资源，所述被访问资源所属的设备可以根据被访问资源的标识确定请求者资源希望访问的资源。
其次，基于上述资源对步骤S110进行解释以及说明。其中，计算第一资源的第一优先级以及第二资源的第二优先级可以包括：根据所述第一资源的第一优先级影响 参数计算所述第一资源的第一优先级；以及根据所述第二资源的第二优先级影响参数计算所述第二资源的第二优先级。此处需要补充说明的是，此处第一资源以及第二资源仅用来表示两种不同的资源，并不对各资源的顺序等进行限定；进一步的，本示例中虽然是以第一资源以及第二资源为例进行说明，但是对于包括更多个资源的示例也可以适用，这同样属于本公开的保护范围。进一步的，参考图2所示，根据所述第一资源的第一优先级影响参数计算所述第一资源的第一优先级可以包括步骤S210以及步骤S220。其中：
在步骤S210中，为所述第一资源的第一优先级影响参数配置权重系数。详细而言：
首先，对上述第一优先级的第一优先级影响参数进行解释以及说明。上述第一优先级的第一优先级影响参数可以包括第一基础优先级、第一资源被订阅总数、第一资源被获取总数以及第一资源被更新总数等等。其中：
第一基础优先级(baseQosLevel)：第一基础优先级可以根据资源的层级进行确定。其中，根资源的基础优先级最高，根资源的直接子资源优先级次之，依次类推。当一个资源可以是多个资源的子资源时，其优先级根据其父资源的优先级进行确定；例如：CSEBase的优先级为最高10，CSEBase的直接子资源<AE>,<node>,<request>的优先级为9，<subscription>可以是CSEBase的子资源，也可以是<AE>等资源的子资源，所以<subscription>资源的优先级根据其父资源进行确定；
第一资源被订阅数(totalNrOfSubscriptions)：第一资源被订阅数可以为订阅方的个数；也可以为订阅资源<subscription>的个数；由于不同的事件可以通过事件通知规则eventNotificationCriteria进行确定，此时第一资源被订阅数为事件通知规则的个数。第一资源被订阅数也可是上述三种情况的任意组合。
第一资源被获取数(totalNrOfRetrieve)：第一资源被获取数可以记录当前总共收到的获取请求数并将其保存到totalNrOfRetrieve中；
第一资源被更新总数(totalNrOfUpdate)：第一资源被更新总数可以记录当前总共收到的获取请求数并保存到totalNrOfUpdate中。此处需要进一步补充说明的是，上述第一基础优先级可以由其中的一个决定因素进行决定，也可以两两组合或者任意三个进行组合或者四个因素集体决定，本示例对此不做特殊限制。
其次，基于上述第一优先级的第一优先级影响参数对上述步骤S210进行解释以及说明。为第一资源的第一优先级影响参数配置权重系数；其中，该权重系数的个数可以为一个、两个、三个或者四个等等；由于权重系数的个数与决定因素的个数是一一对应的，因此，当第一优先级由一个第一优先级影响参数进行确定时，可以配置一个权重系数；当第一优先级由两个第一优先级影响参数进行确定时，可以配置两个权重系数，依次类推，在此不再赘述。
在步骤S220中，对所述第一优先级影响参数以及所述优先级影响参数对应的权 重系数进行运算得到所述第一优先级。详细而言：
当上述权重系数配置完成以后，可以对第一优先级影响参数以及第一资源的优先级影响参数对应的权重系数进行运算得到第一优先级；其中，该运算可以包括相乘和/或相加等等，也可以包括其他运算，例如可以是取整或者取余等等，本示例对此不做特殊限制。举例而言：当第一优先级由四个第一优先级影响参数决定时，则求积运算的过程可以为：第一求积运算结果＝d1*baseQosLevel；第二求积运算结果＝d2*totalNrOfSubscriptions；第三求积运算结果＝d3*totalNrOfRetrieve；第四求积运算结果＝d4*totalNrOfUpdate。其中，d1、d2、d3以及d4分别为第一权重系数、第二权重系数、第三权重系数以及第四权重系数。因此，第一优先级可以为：dynamicQosLevel＝d1*baseQosLevel+d2*totalNrOfSubscriptions+d3*totalNrOfRetrieve+d4*totalNrOfUpdate。此处需要补充说明的是，在上述表达式中，d1、d2、d3以及d4至少有一个是不为零的；并且，d1、d2、d3以及d4的大小可以根据不同业务系统的需要进行调节；例如，一个系统以消息通知为主要业务，则d1以及d2的比重可以增加，d3以及d4的比重可以减小；又例如，一个业务系统主要是被动接收查询请求，则d2的比重可以增加，其他三个参数的比重相对减小。进一步的，由于第二优先级的计算方法与第一优先级的计算方法相同，因此本公开对此不再赘述。
进一步的，为了便于上述第一优先级以及第二优先级的计算，还需要获取各优先级的优先级影响参数。具体的可以包括：获取所述第一资源的第一优先级影响参数以及所述第二资源的第二优先级影响参数。其中，由于各优先级影响参数可以包括基础优先级(baseQosLevel)、资源被订阅数(totalNrOfSubscriptions)、资源被获取数(totalNrOfRetrieve)以及资源被更新总数(totalNrOfUpdate)等等；因此，各资源优先级影响参数可以从各操作请求的发送方处进行获取。
在步骤S120中，判断所述第一资源的第一优先级是否大于第二资源的第二优先级。详细而言：
当上述第一资源的第一优先级以及第二资源的第二优先级计算完成后，判断第一资源的第一优先级是否大于第二资源的第二优先级。例如，第一资源的第一优先级为58，第二资源的第二优先级为42，则可以判断第一资源的第一优先级大于第二资源的第二优先级。
在步骤S130中，在判断所述第一优先级大于所述第二优先级时，执行所述第一资源对应的第一操作请求。举例而言：
当根据上述优先级计算方法得到的第一优先级的计算结果大于第二优先级的计算结果时，可以直接先执行第一资源对应的第一操作请求。其中，该第一操作请求可以包括获取Retrieve、创建Create、更新Update、删除Delete以及Notify等等，也可以包括其他操作，例如可以是增加以及合并等等，本示例对此不做特殊限制。通过先处理优先级较高的资源订阅请求，避免了由于资源订阅请求数量过多造成的在响应资 源订阅请求的同时引起混淆的问题，同时减少了系统的负担。
进一步的，当上述第一资源订阅请求执行完成以后，可以间隔一预设时间(可以为3min或者5min，也可以是其他时间，本示例对此不做特殊限制)执行上述第二资源对应的操作请求，也可以在CSE空闲时，执行上述第二资源对应的操作请求，本示例对此不做特殊限制。通过该方式，可以避免系统长久的处于不工作状态带而引起的系统处于休眠不能及时接收其他设备发送的资源订阅请求的问题，提升了整个系统的工作效率。此处需要进一步补充说明的是，本示例中虽然是以第一资源以及第二资源为例进行说明，但是对于包括更多个资源的示例也可以适用，这同样属于本公开的保护范围。
进一步的，为了对接收到的第一操作请求以及第二操作请求的合法性进行验证，还需要对第一操作请求的第一发送者以及第二操作求的第二发送者进行注册，参考图3所示，具体的可以包括步骤S310以及步骤S320。其中：
在步骤S310中，接收第一操作请求的第一发送者发送的第一注册请求以及第二操作请求的第二发送者发送的第二注册请求。详细而言：
CSE接收第一操作请求的第一发送者发送的第一注册请求以及第二操作请求的第二发送者发送的第二注册请求；其中，第一发送者可以包括多个第一设备，例如可以为AE1、AE2、……、AEN等等；第二发送者可以包括多个第二设备，例如可以为AE1、AE2、……、AEM等等；此处需要补充说明的是，M和N的数值可以相同，也可以不同，本示例对此不做特殊限制。
在步骤S320中，响应所述第一注册请求以及第二注册请求，根据所述第一发送者的第一身份标识以及第二发送者的第二身份标识对所述第一发送者以及第二发送者进行注册。详细而言：
当CSE接收到上述第一注册请求以及第二注册请求后，响应该第一注册请求以及第二注册请求，并根据第一发送者的第一身份标识以及第二发送者的第二身份标识对第一发送者以及第二发送者进行注册。通过对各发送者进行注册，便于当接收到发送者发送的订阅请求时，可以根据标识判断请求的合法性，提升整个系统的安全。
进一步的，被请求资源可以为组资源。当多个被请求资源所在的实体注册完成后，为多个被请求资源创建组资源。参考图4所示，该组资源中可以包括如下参数：设备类别(memberType)、当前设备数量(currentNrOfMembers)、设备最大数量(MaxNrOfMembers)、设备身份标识(memberIDs)、组资源被订阅次数(currentNrOfSubscriptions)、组资源被获取次数(totalNrOfRetrieve)、组资源被更新次数(totalNrOfUpdate)、组资源基础优先级(baseQosLevel)、组资源动态优先级(dynamicQosLevel)、组资源当前动态优先级起始时间(dynamicQosStartTime)以及扇出点(fanOutPoint)。
本公开还提供了另一种基于优先级的资源处理方法。参考图5所示，该基于优先 级的资源处理方法可以包括步骤S510-步骤S530。其中：
在步骤S510中，接收第一成员设备发送的第三更新请求以及第二成员设备发送的第四更新请求。详细而言：
首先，上述第一成员设备例如可以是烟雾传感器(AEx)，第二成员设备例如可以是温度传感器(AEy)；进一步的，当AEx以及AEy中有新的信息更新时，可以向CSE发送第三更新请求以及第四更新请求；当CSE监听到AEx以及AEy发送的第三更新请求以及第四更新请求后，接收该第三更新请求以及第四更新请求。
在步骤S520中，判断所述第一成员设备的第三优先级是否大于第二成员设备的第四优先级。详细而言：
当CSE接收到上述第三更新请求以及第四更新请求后，判断第三更新请求的第三优先级是否大于第四更新请求的第四优先级。其中，第三更新请求的第三优先级以及第四更新请求的第四优先级可以根据各成员设备的自身因素进行决定。
进一步的，为了便于第三优先级以及第四优先级的判断，还需要对第三优先级以及第四优先级进行计算，具体的可以包括：计算所述第一容器的第三优先级以及所述第二容器的第四优先级。详细而言：
首先，配置权重系数；其中，该权重系数的个数可以为一个、两个、三个或者四个等等；由于权重系数的个数与决定因素的个数是一一对应的，因此，当第三优先级由一个决定因素进行确定时，可以配置一个权重系数；当第三优先级由两个决定因素进行确定时，可以配置两个权重系数，依次类推，在此不再赘述；
进一步的，当上述权重系数配置完成以后，可以利用决定因素与决定因素对应的权重系数相乘得到一个或多个乘积。举例而言：第三优先级由四个决定因素决定时，则求积运算的过程可以为：第一求积运算结果＝d1*baseQosLevel；第二求积运算结果＝d2*totalNrOfSubscriptions；第三求积运算结果＝d3*totalNrOfRetrieve；第四求积运算结果＝d4*totalNrOfUpdate。其中，d1、d2、d3以及d4分别为权重系数；d1、d2、d3以及d4的大小可以根据不同业务系统的需要进行调节；例如，一个系统以消息通知为主要业务，则d1以及d2的比重可以增加，d3以及d4的比重可以减小；又例如，一个业务系统主要是被动接收查询请求，则d2的比重可以增加，其他三个参数的比重相对减小；
更进一步的，当决定第三优先级的决定因素为一个时，可以直接将求积运算的结果作为该第三优先级；例如：可以将d1*baseQosLevel或者d2*totalNrOfSubscriptions或者d3*totalNrOfRetrieve或者d4*totalNrOfUpdate直接作为第三优先级；当决定第三优先级的决定因素为多个时，可以将多个求积运算结果进行相加得到第三优先级，例如：dynamicQosLevel＝d1*baseQosLevel+d2*totalNrOfSubscriptions+d3*totalNrOfRetrieve+d4*totalNrOfUpdate；也可以两两相加或者任意三个组合相加，本示例对此不做特殊限制。进一步的，由于第四优先级的计算方法与第三优先级的计 算方法相同，因此本公开对此不再赘述。
在步骤S530中，在判断所述第三优先级大于所述第四优先级时，优先执行所述第三更新请求。当第一发送者订阅了所述组资源的变化信息时，将响应所述第三更新请求的通知消息发送至所述第一发送者。详细而言：
当根据上述优先级计算方法得到的第三优先级的计算结果大于第四优先级的计算结果时，可以直接将响应第三更新请求的确认消息发送至第一操作请求的第一发送者。通过先处理优先级较高的更新请求，避免了由于操作请求数量过多造成的在响应操作请求的同时引起混淆的问题，同时减少了系统的负担。
进一步的，执行第三更新请求后，可以间隔第二预设时间(可以为3min或者5min，也可以是其他时间，本示例对此不做特殊限制)执行第四更新请求。进一步，当第一发送者订阅了所述组资源的变化时，将响应第三更新请求的通知消息发送给第一发送方，可以间隔第二预设时间(可以为3min或者5min，也可以是其他时间，本示例对此不做特殊限制)，将响应第四更新请求的通知消息发送至第二发送者，也可以在CSE空闲时，将响应第四更新请求的通知消息发送至第二发送者，本示例对此不做特殊限制。通过该方式，可以避免系统长久的处于不工作状态带而引起的系统处于休眠不能及时接收其他设备发送的操作请求的问题，提升了整个系统的工作效率。
进一步的，被请求资源可以是非组资源，如容器资源等。参考图6所示，该容器资源中可以包括如下参数：实例最大数量(maxNrOfInstances)、最大字节数(maxByteSize)、当前最大实例数(currentNrOfInstances)、当前字节数(currentByteSize)、组资源被订阅次数(currentNrOfSubscriptions)、组资源被获取次数(totalNrOfRetrieve)、组资源被更新次数(totalNrOfUpdate)、组资源基础优先级(baseQosLevel)、组资源动态优先级(dynamicQosLevel)、实例内容(contentInstance)以及已订阅内容(subscription)等等。
本公开还提供了一种基于优先级的资源处理系统。参考图7所示，该基于优先级的资源处理系统可以包括优先级计算模块710、优先级判断模块720以及操作请求执行模块730。其中：
接收模块710可以用于计算第一资源的第一优先级以及第二资源的第二优先级。
优先级判断模块720可以用于判断所述第一资源的第一优先级是否大于第二资源的第二优先级。
资源订阅请求执行模块730可以用于在判断所述第一优先级大于所述第二优先级时，执行所述第一资源对应的第一操作请求。
上述基于优先级的资源处理系统中各模块的具体细节已经在对应的基于优先级的资源处理方法中进行了详细的描述，因此此处不再赘述。
此外，尽管在附图中以特定顺序描述了本公开中方法的各个步骤，但是，这并非要求或者暗示必须按照该特定顺序来执行这些步骤，或是必须执行全部所示的步骤才 能实现期望的结果。附加的或备选的，可以省略某些步骤，将多个步骤合并为一个步骤执行，以及/或者将一个步骤分解为多个步骤执行等。
