Abstract

A multi-resource subscription association method in an M2M system is provided. According to an embodiment of the present invention, the multi-resource subscription notification method allows a subscription association resource to receive notification messages from a plurality of subscription resources, and determine whether the notification messages satisfy a specific condition so as to transmit a notification message to a user application. Therefore, an M2M platform manages/notifies multiple subscriptions by associating the multiple data with multiple subscriptions, thereby enabling a load of a user application and an overhead in a network to be reduced.

Description

M2M 시스템에서 다중 리소스 구독 연관 방법How to Associate Multiple Resource Subscriptions in an M2M System
본 발명은 IoT(Internet of Things)/M2M(Machine to Machine) 기술에 관한 것으로, 더욱 상세하게는 M2M 플랫폼에서 구독/통지 방법에 관한 것이다.The present invention relates to Internet of Things (IoT) / Machine to Machine (M2M) technology, and more particularly, to a subscription / notification method in an M2M platform.
IoT/M2M 서비스는 다양한 데이터를 취득하여 취득된 데이터들이 사전에 정해진 조건을 동시에 만족하는 경우에 특정 동작을 수행하는 과정에 의해 구현되는 것이 일반적이다.The IoT / M2M service is generally implemented by a process of performing a specific operation when data acquired by acquiring various data satisfies a predetermined condition at the same time.
서비스 애플리케이션은 데이터들을 효율적으로 취득하기 위해서 구독(subscription)을 수행할 수 있다. 필요한 데이터가 다양한 리소스들로부터 제공되는 다양한 데이터들인 경우, 구독을 다중으로 수행해야 한다.The service application may perform a subscription to efficiently obtain data. If the required data is a variety of data provided from various resources, multiple subscriptions must be performed.
도 1에는 창문, 블라인드 및 온도계의 데이터들을 취득하기 위해, <window> 리소스, <blind> 리소스 및 <thermometer> 리소스를 구독하고 있는 상황을 나타내었다.FIG. 1 illustrates a situation in which a <window> resource, a <blind> resource, and a <thermometer> resource are subscribed to in order to obtain data of a window, a blind, and a thermometer.
창문이 "open" 되면 <sub1> 리소스에 의해 사용자 애플리션에게 통지가 이루어지고, 블라인드가 "open" 되면 <sub2> 리소스에 의해 사용자 애플리케이션에게 통지가 이루어지며, 온도가 "34℃"가 되면 <sub3> 리소스에 의해 사용자 애플리케이션에게 통지가 이루어진다.When the window is "open", the user application is notified by the <sub1> resource. When the window is "open", the user application is notified by the <sub2> resource. When the temperature reaches "34 ° C", the < sub3> The resource is notified to the user application.
이에 따라, 사용자 애플리케이션은 많은 통지들을 수신하게 되는데, 수신된 통지들을 다시 분석하여 데이터들이 특정 조건을 만족하는지 파악하여야 하는 부담이 있다.As a result, the user application receives a number of notifications, with the burden of analyzing the received notifications again to see if the data meets a particular condition.
이를 테면, 창문이 "open" 되었고, 블라인드가 "open" 되었으며, 온도가 "34℃"가 되었는지에 대해, 통지 메시지들을 모두 분석하여 파악해야 한다. 사용자 애플리케이션은 모두를 충족하는 경우에만 특정 동작을 수행하기 때문에, 만약 하나만이라도 충족하지 못하는 경우 통지와 분석은 불필요한 것이 되어 버린다.For example, all notification messages must be analyzed to determine whether the window is "open", the blind is "open", and the temperature is "34 ° C". Because user applications only perform certain actions when all are met, notification and analysis become unnecessary if only one is not met.
나아가, 이는 네트워크 관점에서도 불필요하게 많은 메시지를 전송하였다는 문제로 이어진다.Furthermore, this leads to the problem of sending a lot of messages unnecessarily from the network point of view.
이를 해결 하기 위한 방안으로, oneM2M 표준에서 규정하는 그룹 기능을 이용하는 방안을 상정할 수 있다. 이를 통해, 통지 메시지를 하나로 통합할 수는 있지만, 통합 메시지는 개별적인 통지 메시지들을 단순 취합한 것에 불과하므로, 본질적인 해결책이 될 수는 없다.As a solution to this problem, it is possible to use a group function defined in the oneM2M standard. This allows us to consolidate notification messages into one, but it is not an inherent solution because the integration message is simply a collection of individual notification messages.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은, M2M 플랫폼에서 다중 데이터에 대한 다중 구독을 연관지어 관리/통지하는 방법을 제공함에 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide a method for managing / notifying multiple subscriptions for multiple data in the M2M platform.
상기 목적을 달성하기 위한 본 발명의 일 실시예에 따른, 다중 리소스 구독 통지 방법은, 구독 연관 리소스가, 다수의 구독 리소스들로부터 통지 메시지들을 수신하는 단계; 구독 연관 리소스가, 통지 메시지들이 특정 조건을 만족하는지 판단하는 단계; 특정 조건을 만족하면, 구독 연관 리소스가 사용자 애플리케이션에 통지 메시지를 전송하는 단계;를 포함한다.According to an embodiment of the present invention for achieving the above object, a multi-resource subscription notification method includes: receiving, by a subscription related resource, notification messages from a plurality of subscription resources; Determining, by the subscription related resource, whether the notification messages satisfy a specific condition; And if the specific condition is satisfied, the subscription related resource sending a notification message to the user application.
그리고, 다수의 구독 리소스들은, 구독 연관 리소스의 제1 속성에 설정되어 있을 수 있다.The plurality of subscription resources may be set in a first property of a subscription related resource.
또한, 본 발명의 일 실시예에 따른, 다중 리소스 구독 통지 방법은, 다수의 구독 리소스들 중 일부가 삭제되면, 구독 연관 리소스의 제1 속성에서 삭제된 구독 리소스를 삭제하는 단계;를 더 포함할 수 있다.In addition, the multi-resource subscription notification method according to an embodiment of the present invention, if some of the plurality of subscription resources is deleted, deleting the deleted subscription resources in the first attribute of the subscription associated resources; Can be.
그리고, 분석 단계는, 통지 메시지들이 특정 조건에 따라 수신되는지 판단할 수 있다.The analyzing step may determine whether notification messages are received according to a specific condition.
또한, 특정 조건은, 구독 연관 리소스의 제2 속성으로 설정되어 있을 수 있다.In addition, the specific condition may be set as the second attribute of the subscription related resource.
그리고, 전송 단계는, 구독 연관 리소스의 제3 속성에 따라 각기 다른 타입의 통지 메시지를 생성하여 전송할 수 있다.In addition, the transmitting may generate and transmit different types of notification messages according to the third attribute of the subscription related resource.
또한, 다수의 구독 리소스들 중 일부는, 구독 연관 리소스의 호스팅 엔티티와 다른 엔티티에 포함되어 있을 수 있다.In addition, some of the plurality of subscription resources may be included in an entity different from the hosting entity of the subscription associated resource.
한편, 본 발명의 다른 실시예에 따른 M2M 시스템은, 사용자 애플리케이션이 실행되는 사용자 단말과 통신하는 통신부; 및 구독 연관 리소스가 다수의 구독 리소스들로부터 통지 메시지들을 수신하면, 구독 연관 리소스가 통지 메시지들이 특정 조건을 만족하는지 판단하고, 특정 조건을 만족하면 구독 연관 리소스가 사용자 애플리케이션에 통지 메시지를 전송하도록 처리하는 프로세서;를 포함한다.On the other hand, M2M system according to another embodiment of the present invention, a communication unit for communicating with the user terminal running the user application; And if the subscription associated resource receives notification messages from multiple subscription resources, the subscription associated resource determines whether the notification messages meet a specific condition, and if the subscription related resource satisfies the specific condition, the subscription associated resource sends a notification message to the user application. A processor;
이상 설명한 바와 같이, 본 발명의 실시예들에 따르면, M2M 플랫폼에서 다중 데이터에 대한 다중 구독을 연관지어 관리/통지함으로써, 사용자 애플리케이션의 부담과 네트워크 상에서의 오버헤드를 감소시킬 수 있게 된다.As described above, according to embodiments of the present invention, by managing and notifying multiple subscriptions to multiple data in the M2M platform, it is possible to reduce the burden on the user application and overhead on the network.

이하에서는 도면을 참조하여 본 발명을 보다 상세하게 설명한다.Hereinafter, with reference to the drawings will be described the present invention in more detail.
본 발명의 실시예에서는 M2M 플랫폼에서 다중 데이터에 대한 다중 구독을 연관지어 관리/통지하는 방안을 제시한다.An embodiment of the present invention proposes a method of managing / notifying multiple subscriptions to multiple data in an M2M platform.
구체적으로, 도 1에 도시된 바와 같이 리소스 마다 개별적인 조건을 만족하는 경우에 개별적인 통지들이 이루어지는 방식이 아닌, 도 2에 도시된 바와 같이 리소스 모두가 조건을 만족하는 경우에 하나의 통지가 이루어지는 방식을 제시한다.Specifically, a method is provided in which one notification is made when all resources satisfy a condition as shown in FIG. 2, not a method in which individual notifications are made when each resource satisfies an individual condition as shown in FIG. 1. present.
부연하면, 전자(도 1)는 개별적인 이벤트에 대해 통지 메시지들이 개별적으로 수신되는 방식이고, 후자(도 2)는 다중 이벤트에 대해 하나의 통지 메시지가 수신되는 방식인 것이다.In other words, the former (FIG. 1) is a manner in which notification messages are individually received for individual events, and the latter (FIG. 2) is a manner in which one notification message is received for multiple events.
사용자 단말에서 실행되는 사용자 애플리케이션은 개별 데이터들이 개별적으로 해당 조건을 충족하였는지에 대해 관심이 있는 것이 아니라, 데이터들 모두가 해당 조건들을 각각 모두 충족하였는지에 관심이 있다는 점을 반영한 것이다.The user application executed in the user terminal is not concerned about whether the individual data satisfies the condition individually, but reflects the fact that all of the data is interested in whether all of the conditions are satisfied.
M2M 플랫폼에서 다중 데이터에 대한 다중 구독을 연관지어 관리/통지할 수 있도록 하기 위해, 본 발명의 실시예에서는 <subscriptionAssociation> 리소스를 제시한다.In order to be able to associate / manage multiple subscriptions to multiple data in the M2M platform, an embodiment of the present invention provides a <subscriptionAssociation> resource.
<subscriptionAssociation> 리소스는, 도 3에 도시된 바와 같이, 다른 리소스들과 함께 M2M 플랫폼에 생성된다. 도 3에서 <subscriptionAssociation> 리소스는, "<subAsso>"로 표기하였다.<subscriptionAssociation> resources are created in the M2M platform along with other resources, as shown in FIG. In FIG. 3, a <subscriptionAssociation> resource is referred to as "<subAsso>".
<subscriptionAssociation> 리소스는, 도 3에 나타낸 바와 같이, 개별 <subscription> 리소스들인 <sub1> 리소스, <sub2> 리소스 및 <sub3> 리소스를 링크하기 위한 <subscription> 리소스들의 ID들을 수록하고 있는 subIDs 속성을 포함한다.The <subscriptionAssociation> resource, as shown in FIG. 3, has a subIDs attribute containing IDs of <sub1> resources, <sub2> resources, and <subscription> resources for linking <sub3> resources, which are individual <subscription> resources. Include.
<subscriptionAssociation> 리소스의 timeWindow 속성은 subIDs 속성으로 지시하는 개별 <subscription> 리소스들 모두로부터 통지 메시지가 수신되었는지 여부를 인식/판단하기 위한 대기 시간이다. The timeWindow attribute of the <subscriptionAssociation> resource is a waiting time for recognizing / determining whether a notification message has been received from all of the individual <subscription> resources indicated by the subIDs attribute.
도 4에는 timeWindow 속성을 개념적으로 나타내었다. 도 4에 나타낸 바와 같이, 3개의 개별 구독에 대해 10초의 timeWindow가 설정된 경우, <subscriptionAssociation> 리소스는 3개의 개별 구독에 의한 통지 메시지들이 최대 10초 내에서는 유효한 값으로 판단한다. 즉, 10초 내에 모든 <subscription> 리소스들로부터 통지들을 모두 수신하는 경우, 조건을 만족하는 것으로 취급한다.4 conceptually illustrates the timeWindow property. As shown in FIG. 4, when a time window of 10 seconds is set for three individual subscriptions, the <subscriptionAssociation> resource determines that notification messages by the three individual subscriptions are valid values within a maximum of 10 seconds. That is, if all notifications are received from all <subscription> resources within 10 seconds, the condition is treated as satisfying.
도 4에 제시한 timeWindow 속성은 예시적인 것에 불과하다. timeWindow 속성은 필요와 목적에 따라 다양하게 구현할 수 있다. 이를 테면, <subscription> 리소스들로부터의 통지들 간 간격을 설정하는 방식이 적용될 수도 있고, 통지들의 순서가 더 한정될 수도 있다.The timeWindow attribute shown in FIG. 4 is merely exemplary. The timeWindow property can be implemented in various ways depending on your needs and purposes. For example, a manner of setting an interval between notifications from <subscription> resources may be applied, and the order of the notifications may be further limited.
경우에 따라서는 개별 구독을 위한 timeWindow를 각각 설정할 수 있다. 또한, 경우에 따라서는 개별 통지 메시지 상에 유효 시간 정보가 기록되어 있을 수 있다. 이러한 경우 해당 유효 시간 정보를 참조하여 다중 데이터(이벤트) 동시 만족 여부를 판별할 수 있다. In some cases, you can set a timeWindow for each individual subscription. In some cases, the valid time information may be recorded on the individual notification message. In this case, it is possible to determine whether multiple data (events) are satisfied simultaneously by referring to the valid time information.
다시 도 3을 참조하여 설명한다. notiType 속성은 <subscriptionAssociation> 리소스에 의해 전송되는 연관 통지 메시지에 포함할 메시지 내용을 지시한다.This will be described with reference to FIG. 3 again. The notiType attribute indicates the message content to be included in the association notification message sent by the <subscriptionAssociation> resource.
notiType 속성에 의해, 연관 통지 메시지에는, 1) 모든 개별 구독들이 조건을 충족하였다는 통지, 즉, 다중 이벤트가 발생하였음을 알리기 위한 통지만이 수록될 수 있고, 2) 이 통지 외에 부가적으로 개별 통지 메시지들 더 포함될 수도 있다.By the notiType attribute, the association notification message may contain only 1) a notification that all individual subscriptions have met the condition, i.e. a notification to indicate that multiple events have occurred, and 2) in addition to this notification, Notification messages may further be included.
<subscriptionAssociation> 리소스와 <subscription> 리소스들 간의 상호 링크를 맺기 위해, <subscriptionAssociation> 리소스 생성시에 <sub1> 리소스, <sub2> 리소스 및 <sub3> 리소스는 <subscriptionAssociation> 리소스를 링크하기 위한 associatedSub 속성을 추가로 설정한다. 이에 따라, <subscription> 리소스의 통지가 <subscriptionAssociation> 리소스의 호스팅 CSE(Hosting Common Service Entity)에 전송될 수 있다.To establish a reciprocal link between the <subscriptionAssociation> resource and the <subscription> resources, when creating a <subscriptionAssociation> resource, the <sub1> resource, <sub2> resource, and <sub3> resource have an associatedSub attribute for linking the <subscriptionAssociation> resource. Set additionally. Accordingly, the notification of the <subscription> resource may be sent to the hosting Common Service Entity (CSE) of the <subscriptionAssociation> resource.
만약 <subscription> 리소스가 다중 이벤트 정보를 구독하고 있는 경우에는, 특정 이벤트만을 <subscriptionAssociation> 리소스를 가진 CSE에 전송할 수 있도록하는 추가 속성/정보를 가질 수 있다.If the <subscription> resource subscribes to multiple event information, it may have additional attributes / information that allows only a specific event to be sent to the CSE with the <subscriptionAssociation> resource.
나아가, 도 5에 도시된 바와 같이, <subscription> 리소스들이 동일 CSE에 모두 포함되지 않고 다수의 CSE들에 분산된 경우에도, <subscriptionAssociation> 리소스 생성이 가능하다.Furthermore, as shown in FIG. 5, even when <subscription> resources are not all included in the same CSE but distributed to multiple CSEs, <subscriptionAssociation> resource generation is possible.
즉, <subscriptionAssociation> 리소스의 subIDs 속성에 설정되는 개별 <subscription> 리소스들은 반드시 동일 CSE에 포함된 <subscription> 리소스들로 한정되지 않는다.That is, individual <subscription> resources set in the subIDs attribute of a <subscriptionAssociation> resource are not necessarily limited to <subscription> resources included in the same CSE.
한편, <subscriptionAssociation> 리소스의 subIDs 속성은 관심 있는 모든 이벤트를 동시에 만족하는지를 판단하는 대상 정보이므로 이 링크를 동적으로 관리할 필요가 있다.On the other hand, since the subIDs attribute of the <subscriptionAssociation> resource is target information for determining whether all events of interest are satisfied at the same time, it is necessary to dynamically manage this link.
예를 들어, 도 6에 제시된 바와 같이, 연관된 개별 구독들 중 하나가 삭제된 경우, 삭제된 개별 <subscription> 리소스를 <subscriptionAssociation> 리소스의 subIDs 속성에서 배제시키는 것이 가능하다.For example, as shown in FIG. 6, if one of the associated individual subscriptions is deleted, it is possible to exclude the deleted individual <subscription> resource from the subIDs attribute of the <subscriptionAssociation> resource.
이 경우, 이후에는 나머지 두 개의 구독들을 대상으로 연관 구독/통지 기능이 제공될 수 있다. 이를 위해, 개별 구독이 삭제되는 경우, 삭제된 개별 <subscription> 리소스의 호스팅 CSE2는 삭제된 개별 <subscription> 리소스의 associatedSub 속성을 참고하여 <subscriptionAssociation> 리소스의 호스팅 CSE1에 삭제를 요청하며, 이에 <subscriptionAssociation> 리소스의 subIDs 속성이 갱신된다.In this case, the related subscription / notification function may be provided to the remaining two subscriptions. To this end, when an individual subscription is deleted, the hosting CSE2 of the deleted individual <subscription> resource requests the deletion from the hosting CSE1 of the <subscriptionAssociation> resource by referring to the associatedSub attribute of the deleted individual <subscription> resource, and thus the <subscriptionAssociation > The subIDs attribute of the resource is updated.
삭제 요청은 CSE2가 <subscriptionAssociation> 리소스의 <deletion> 가상 리소스를 대상으로 DELETE를 요청하는 방식으로 수행되며, DELETE 요청의 Content에는 삭제된 <subscription> 리소스의 ID가 포함된다.The delete request is performed by CSE2 requesting a DELETE for the <deletion> virtual resource of the <subscriptionAssociation> resource. The content of the DELETE request includes the ID of the deleted <subscription> resource.
삭제된 개별 <subscription> 리소스의 호스팅 CSE와 <subscriptionAssociation> 리소스의 호스팅 CSE가 동일한 경우에는, 호스팅 CSE에 의한 자동 갱신이 가능하다.If the hosting CSE of the deleted individual <subscription> resource is the same as the hosting CSE of the <subscriptionAssociation> resource, automatic renewal by the hosting CSE is possible.
한편, 위와 같이 연관된 개별 구독들 중 하나가 삭제된 경우, 연관 구독이 무의미지는 경우가 있을 수 있으며, 이 경우에는 연관 통지를 수신하지 않도록 처리할 필요가 있다.On the other hand, when one of the associated individual subscriptions are deleted as described above, there may be a case in which the associated subscription is meaningless, in which case it is necessary to process not to receive the association notification.
이에, 연관된 개별 구독들 중 하나가 삭제되어, <subscriptionAssociation> 리소스의 subIDs 속성이 갱신되는 경우, 연관 통지의 수신 여부를 지시하는 속성인 subMembersDeletionAllowed 속성을 <subscriptionAssociation> 리소스에 미리 설정할 수 있다.Therefore, when one of the associated individual subscriptions is deleted and the subIDs attribute of the <subscriptionAssociation> resource is updated, the subMembersDeletionAllowed attribute, which is an attribute indicating whether to receive the association notification, may be previously set in the <subscriptionAssociation> resource.
subMembersDeletionAllowed이 True 이면, 개별 구독들 중 하나가 삭제되어 <subscriptionAssociation> 리소스의 subIDs 속성이 갱신된 경우에도 연관 통지가 이루어진다. 반면, subMembersDeletionAllowed이 False 이면, 동일한 경우에 연관 통지는 이루어지지 않는다.If subMembersDeletionAllowed is True, the association notification is made even if one of the individual subscriptions is deleted and the subIDs attribute of the <subscriptionAssociation> resource is updated. On the other hand, if subMembersDeletionAllowed is False, no association notification is made in the same case.
나아가, 위와 같이 연관된 개별 구독들 중 하나가 삭제되어 <subscriptionAssociation> 리소스의 subIDs 속성이 갱신되는 경우, <subscriptionAssociation> 리소스의 생성자에 이를 통지할 필요가 있다. 이를 위해, <subscriptionAssociation> 리소스에 생성자 정보가 수록된 creator 속성을 포함시키는 것이 가능하다.Furthermore, when one of the associated individual subscriptions is deleted and the subIDs attribute of the <subscriptionAssociation> resource is updated, it is necessary to notify the creator of the <subscriptionAssociation> resource. To this end, it is possible to include a creator attribute containing creator information in a <subscriptionAssociation> resource.
