请参考图2，其示出了本申请一示例性实施例提供的订阅流程的示意图。如图2所示，该订阅流程可以包括如下步骤：Please refer to Figure 2, which shows a schematic diagram of a subscription process provided by an exemplary embodiment of the present application. As shown in Figure 2, the subscription process may include the following steps:
S21，订阅设备(即订阅发起者Initiator)发起订阅流程，发送订阅请求(subscribe request)消息。S21, the subscription device (i.e., the subscription initiator) initiates the subscription process and sends a subscribe request (subscribe request) message.
subscribe request消息的消息内容可以如下述表1所示。The message content of the subscribe request message can be shown in Table 1 below.
表1Table 1
Figure PCTCN2022106111-appb-000001
Figure PCTCN2022106111-appb-000001
在该subscribe request消息中，keepsubscriptions参数的含义是：publisher(发布者)接收到其取值为FALSE的subscribe request时，需要删除所有initiator与publisher(发布者，在本申请实施例中也称为被订阅设备)间的订阅关系。Maxintervalceiling规定了通知消息的最大间隔的最大值。Minintervalfloor规定了通知消息的最小间隔的最小值。In the subscribe request message, the meaning of the keepsubscriptions parameter is: when the publisher (publisher) receives a subscribe request whose value is FALSE, it needs to delete all initiators and publishers (publisher, also called the publisher in the embodiment of this application). Subscription relationship between subscribing devices). Maxintervalceiling specifies the maximum value of the maximum interval for notification messages. Minintervalfloor specifies the minimum value of the minimum interval for notification messages.
S22，publisher收到上述订阅请求后，检查Initiator是否有权限订阅该订阅目标(被订阅的资源)。通过报告数据请求消息发送订阅目标的当前状态(比如属性(例如温度值、灯的开关等)或者事件)。S22. After receiving the above subscription request, the publisher checks whether the Initiator has the permission to subscribe to the subscription target (subscribed resource). Send the current status of the subscription target (such as properties (such as temperature values, light switches, etc.) or events) through report data request messages.
S23，Initiator收到报告数据请求消息后回复status response(状态响应消息)，该消息指示其收到了订阅目标的当前状态。S23. After receiving the report data request message, the Initiator replies with a status response (status response message), which indicates that it has received the current status of the subscription target.
S24，Publisher收到S23中的status response之后，会生成并返回一个subscribe response(订阅响应)消息。S24, after Publisher receives the status response in S23, it will generate and return a subscribe response message.
该消息subscribe response可以包括如下述表2所示的内容。The message subscribe response may include content as shown in Table 2 below.
表2Table 2
Figure PCTCN2022106111-appb-000002
Figure PCTCN2022106111-appb-000002
在上述表2中，各个参数的含义如下：In the above Table 2, the meaning of each parameter is as follows:
Subscribe ID：订阅ID，用来标识两个设备间的一个订阅关系；Subscribe ID: Subscription ID, used to identify a subscription relationship between two devices;
MinInterval：通知消息(即数据报告data report消息)的最小间隔；MinInterval: the minimum interval for notification messages (i.e. data report messages);
MaxInterval：通知消息的最大间隔。MaxInterval: The maximum interval for notification messages.
S25-S26：当订阅目标发生变化时，Publisher会发送一个通知消息data report给Initiator，Initiator回复一个状态响应(status response)消息。S25-S26: When the subscription target changes, Publisher will send a notification message data report to the Initiator, and the Initiator will reply with a status response message.
在上述方案中，subscribe request消息中必须携带MaxIntervalCeiling和MinIntervalfloor这两个字段。但是在keepsubscriptions＝false时，这两个字段并没有实际的意义，并且，目标对于在keepsubscriptions＝false的情况下，订阅设备如何设置MaxIntervalCeiling和MinIntervalfloor，还没有明确的方案，导致目前的订阅请求消息中的MaxIntervalCeiling和MinIntervalfloor字段的设置不统一，导致不同厂家的设备之间的消息订阅可能存在不兼容的情况，导致消息订阅的应用场景受限。In the above solution, the subscribe request message must carry the two fields MaxIntervalCeiling and MinIntervalfloor. However, when keepsubscriptions=false, these two fields have no actual meaning. Moreover, the target has no clear solution for how to set MaxIntervalCeiling and MinIntervalfloor for the subscription device when keepsubscriptions=false, resulting in the current subscription request message. The settings of the MaxIntervalCeiling and MinIntervalfloor fields are not uniform, resulting in possible incompatible message subscriptions between devices from different manufacturers, resulting in limited application scenarios for message subscriptions.
请参考图3，其示出了本申请一个实施例提供的订阅消息处理方法的流程图，该方法可以由订阅设备执行，比如，该订阅设备可以是图1所示的网络架构中的物联网设备110或者配置设备120中的一个；该方法可以包括如下几个步骤：Please refer to Figure 3, which shows a flow chart of a subscription message processing method provided by an embodiment of the present application. This method can be executed by a subscription device. For example, the subscription device can be the Internet of Things in the network architecture shown in Figure 1 Device 110 or one of the configuration devices 120; the method may include the following steps:
步骤301，生成第一订阅请求消息；第一订阅请求消息用于删除订阅设备与被订阅设备之间的订阅关系；第一订阅请求消息中不包含指定参数，或者，第一订阅请求消息中包含的指定参数的参数值为特定值或随机值；指定参数包括第一参数和第二参数中的至少一种；第一参数用于指示订阅数据报告的最大间隔的最大值；第二参数用于指示订阅数据报告的最小间隔的最小值；订阅数据报告用于指示被订阅设备订阅的资源的状态。Step 301: Generate a first subscription request message; the first subscription request message is used to delete the subscription relationship between the subscribing device and the subscribed device; the first subscription request message does not contain specified parameters, or the first subscription request message contains The parameter value of the specified parameter is a specific value or a random value; the specified parameter includes at least one of a first parameter and a second parameter; the first parameter is used to indicate the maximum value of the maximum interval for subscribing to data reports; the second parameter is used to Minimum value indicating the minimum interval for subscription data reports; subscription data reports are used to indicate the status of resources subscribed to by the subscribing device.

S61-S63，Initiator发起一个订阅请求流程，需要生成一个订阅请求消息：在该请求消息中设置源、目标、S Flag、Dsiz Flag、将keepsubscriptions设定为TRUE，并设置MaxIntervalCeiling和MinIntervalfloor字段的参数值。S61-S63, the Initiator initiates a subscription request process and needs to generate a subscription request message: set the source, target, S Flag, Dsiz Flag, set keepsubscriptions to TRUE in the request message, and set the parameter values of the MaxIntervalCeiling and MinIntervalfloor fields. .
S64-S65，如果Initiator发起的订阅流程是一个取消所有订阅的流程，则：Initiator将keepsubscriptions设定为FALSE。另外，针对MaxIntervalCeiling和MinIntervalfloor的设定有一下几种可选的方案：S64-S65, if the subscription process initiated by the Initiator is a process of canceling all subscriptions, then: the Initiator sets keepsubscriptions to FALSE. In addition, there are several options for setting MaxIntervalCeiling and MinIntervalfloor:
1)不携带MaxIntervalCeiling和MinIntervalfloor，即两个参数对于subscribe request消息不是必要消息，仅keepsubscriptions＝TRUE时需要携带；1) MaxIntervalCeiling and MinIntervalfloor are not carried, that is, the two parameters are not necessary for the subscribe request message, and only need to be carried when keepsubscriptions=TRUE;
2)MaxIntervalCeiling和MinIntervalfloor设定为0、其他相等的数值、或者其他特殊的数值；2) MaxIntervalCeiling and MinIntervalfloor are set to 0, other equal values, or other special values;
3)MaxIntervalCeiling和MinIntervalfloor设定为NULL；3) MaxIntervalCeiling and MinIntervalfloor are set to NULL;
4)MaxIntervalCeiling和MinIntervalfloor可以设定为任何值，但是如果keepsubscriptions＝FALSE，则publisher不去处理这两个值。4) MaxIntervalCeiling and MinIntervalfloor can be set to any value, but if keepsubscriptions=FALSE, the publisher will not process these two values.
S66，Initiator向Publisher发送上述订阅请求消息。S66, Initiator sends the above subscription request message to Publisher.
S67-S68，Publisher收到上述订阅请求消息之后，会判定Initiator是否有权限执行上述操作。S67-S68, after receiving the above subscription request message, Publisher will determine whether the Initiator has the authority to perform the above operation.
如果订阅请求消息中的keepsubscriptions＝FALSE。则针对S64步骤MaxIntervalCeiling和MinIntervalfloor的设定，判定消息格式的合法性。如果合法性检测通过，则Publisher立即结束与Initiator间的所有订阅关系。If keepsubscriptions=FALSE in the subscription request message. Then determine the legality of the message format based on the settings of MaxIntervalCeiling and MinIntervalfloor in step S64. If the legality test passes, the Publisher immediately ends all subscription relationships with the Initiator.
如果订阅请求消息中的keepsubscriptions设定为TRUE，则Publisher建立新的订阅关系。If keepsubscriptions in the subscription request message is set to TRUE, Publisher establishes a new subscription relationship.
S69-S610，Publisher向Initiator发送数据报告消息，Initiator向Publisher返回状态响应消息。S69-S610, Publisher sends a data report message to the Initiator, and the Initiator returns a status response message to the Publisher.
其中，上述S69-S610为可选步骤；其中，即使在取消订阅场景下，Initiator也可能最后一次发送data report消息。其中，200OK通常指接收成功的应答消息。Among them, the above S69-S610 are optional steps; among them, even in the unsubscription scenario, the Initiator may send the data report message for the last time. Among them, 200OK usually refers to a successful response message.
S611，在取消订阅场景下，在删除Initiator对Publisher中的资源的订阅关系之后，Publisher针对subscribe request回复一个status response，指示其已经删除所有订阅关系。该步骤也为可选步骤。S611, in the cancellation scenario, after deleting the subscription relationship of the Initiator to the resources in the Publisher, the Publisher replies with a status response to the subscribe request, indicating that it has deleted all subscription relationships. This step is also optional.
S612，在订阅场景，在建立Initiator对Publisher中的资源的新的订阅关系之后，Publisher针对subscribe request回复一个status response，其可以表示订阅成功。S612, in the subscription scenario, after establishing a new subscription relationship between the Initiator and the resources in the Publisher, the Publisher replies with a status response to the subscribe request, which can indicate that the subscription is successful.
综上所述，在本申请实施例所示的方案中，订阅设备向被订阅设备取消订阅时，可以生成不包含指定参数的第一订阅消息，或者，生成包含的指定参数的参数值为特定值或随机值的第一订阅消息，提供了在取消订阅的场景下，对订阅请求消息中的用于指示订阅数据报告的最大间隔的最大值和/或最小值的参数的明确的设置方式，统一了取消消息订阅的行为，扩展了消息订阅的应用场景。To sum up, in the solution shown in the embodiment of this application, when the subscribing device unsubscribes from the subscribed device, it can generate a first subscription message that does not contain specified parameters, or generate a first subscription message that contains specified parameters with a specific parameter value. The first subscription message with a value or a random value provides a clear way to set the parameters in the subscription request message that indicate the maximum value and/or minimum value of the maximum interval for subscription data reporting in the unsubscription scenario. Unified the behavior of canceling message subscriptions and expanded the application scenarios of message subscriptions.
