Introduction(1/2)

• Smart devices, such as smart phone & tablet PC, are being widely introduced to users– equipped with mobile operating system such as IOS, Android, Windows 8

– act as a service platform of various applications

• Smart devices are recently emerging as a main control device of home services– to monitor & control home devices at home and out of home

– replace the traditional fixed on the wall

• How to provide an interoperability between the remote home control protocols and the HES protocols?– Various kinds of remote home control protocols according to the vendors

– Multiple HES protocol standards such as UPnP, Knx, Echonet, etc.

Scope

• Addresses the application interoperability model based on ISO/IEC 18012-2 between the smart device and the HES for home control services.– ISO/IEC 18012-2 addresses basic taxonomy and application model

aspects related to the operational mode of interoperable HESs.

• Defines the application objects needed to support the service, and describes the generic interface between those objects. – The use cases of the generally available home control service with

smart devices are listed.– To support those use cases, events and their flows for command, status

report or data, which are exchanged between the application objects of the application interoperability model, are defined.

• Use cases– Logging in and obtaining initial data– Obtaining a list of home devices– Controlling a home device – Notification of home device event– Changing the login password

• For each use case, the followings are specified;– Events exchanged between the application objects through the event bus within the

Interoperability Domain– Parameters included in each event– The event flow
