Introduction(1/2) 3 The community service is a shared service at the complex level –Collective residence such as apartment, mixed use building, etc. For the community service, the community system should be installed inside the complex –requires an interface with the HES Community System HES CCTV monitoring Elevator stop request Lobby door control Vehicle location guide Complex Network Parking notificationCommunity announcement GatewayMonitor Remote utility metering Community Service

Introduction(2/2) 4 Dev UPnP Knx Echonet HES Gateway Community System Ethernet How to provide an interoperability between community interface protocols and home network protocols? –Various kinds of community interface protocols according to the vendors –Multiple HES protocol standards such as UPnP, Knx, Echonet, etc. Community Interface Protocols A, B, C… HES Protocols A’, B’, C’…

Scope Addresses the application interoperability model based on ISO/IEC the community system and the HES for the community service. –ISO/IEC 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 interrelationship among those objects. –The use cases of the generally available community service are listed. –To support those services, events and their flows for command, status report or data, which are exchanged among the application objects of the application interoperability model, are defined. 8
