FOREWORD
1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees established
by the respective organization to deal with particular fields of technical activity. ISO and IEC technical
committees collaborate in fields of mutual interest. Other international organizations, governmental and non-
governmental, in liaison with ISO and IEC, also take part in the work.
2) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested IEC and ISO National bodies.
3) IEC and ISO documents have the form of recommendations for international use and are accepted by IEC and
ISO National bodies in that sense. While all reasonable efforts are made to ensure that the technical content of
IEC and ISO documents is accurate, IEC and ISO cannot be held responsible for the way in which they are
used or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC and ISO National bodies undertake to apply IEC and ISO
documents transparently to the maximum extent possible in their national and regional publications. Any
divergence between any IEC and ISO document and the corresponding national or regional publication shall be
clearly indicated in the latter.
5) IEC and ISO do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC and ISO marks of conformity. IEC and ISO are not
responsible for any services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this document.
7) No liability shall attach to IEC and ISO or their directors, employees, servants or agents including individual
experts and members of its technical committees and IEC and ISO National bodies for any personal injury,
property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including
legal fees) and expenses arising out of the publication, use of, or reliance upon, this ISO/IEC document or any
other IEC and ISO documents.
8) Attention is drawn to the Normative references cited in this document. Use of the referenced publications is
indispensable for the correct application of this document.

patent rights. IEC and ISO shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
A home cluster system is implemented by interconnecting several devices to deliver one or
more applications. A cluster can function independently of other clusters. Cluster devices
include sensors, actuators, a controller, and user interfaces. Multiple home cluster systems
can be installed and operated in a single home for the following reasons.
– There are various types of application domains in the home such as lighting, safety, air
conditioning, telecommunications, and audio/video, etc. One or more applications are
implemented by the constituents of a cluster. If a user purchases several applications,
multiple home cluster systems can be installed in a home.
– Home application vendors usually provide systems implemented in clusters of required
devices. Depending on the user's needs, several application systems, possibly from
different manufacturers, can be installed in a home as separate clusters.
A customer can access a device in a cluster via a user interface provided for that cluster. With
multiple clusters a user needs to learn how to operate a range of different interfaces. This
document provides the cluster-to-cluster interworking foundation necessary for a single
common user interface to manage applications in multiple clusters.
Application-to-application and the resulting device-to-device collaboration are essential for
providing integrated services in a multi-device HES environment. For example, if a fire
monitoring system detects a fire, the indoor lights should be turned on and the fire
announcements should be broadcast through available speakers in the house for prompt
evacuation of the residents, the ventilation blowers should be stopped to avoid spreading the
fire, and the public fire service should be contacted. This needs collaboration among fire
detectors, indoor lights, speakers, HVAC and telecommunication devices. If the devices are
located in different clusters, cluster-to-cluster interworking is needed for collaboration among
them.
In practice, a safety monitoring cluster might send out a fire-detected message and a lighting
cluster might be ready to activate a lighting scene that alerts the occupant by turning on or
flashing the appropriate lights. However, the two clusters might not have a way to
communicate with each other especially if supplied by different manufacturers possibly using
different protocols and messages. This document solves that problem by providing the
necessary interworking and interoperability functionality to ensure that the clusters can work
together.
When the cluster systems are in different HANs or use different protocols, the interworking is
accomplished using the HES gateway (ISO/IEC 15045 series) and rela
