User gets information from Virtual Entity-level service
Virtual Entity-level service provides access to Virtual Entity information,
augmenting sensor information with entity information (entityId, entityType or
several attributes), thus changing the abstraction level. Figure 52 shows the
Subscribe/Notify-pattern, which can be used to get updates about an Attributes
value.
Figure 52 : User subscribes for updates of VE-attribute.Service gets sensor value from Device
The Sensor Device in Figure 53 pushes an updated sensor value using the
Functional Component Flow Control & Reliability to an IoT Service. Besides the
Push-pattern Request/Response and Subscribe/Notify-pattern are possible.
Figure 54 shows a similar situation but the information is pushed up to the VE
Service.
