FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC 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 National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC 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 National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees 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 IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 63240-2 has been prepared by IEC systems committee AAL: Active
Assisted Living.
The text of this International Standard is based on the following documents:

INTRODUCTION
IEC SyC AAL is developing an architecture model and a reference architecture for AAL to guide
the development and deployment of AAL services and technologies. IEC 63240 consists of the
following parts, under the general title Active assisted living (AAL) reference architecture and
architecture model:
• Part 1: Reference architecture;
• Part 2: Architecture model.
This document provides information to ensure usability and accessibility from the earliest stages
of design and provides guidance to developers on how to incorporate these requirements.
Additional requirements such as security, privacy, and trustworthiness are introduced and
considered.
This document captures the results the work of SyC AAL on architecture and interoperability.
This document reflects contributions and discussions by SyC AAL experts, mirror committees
and liaison members. This document also contains material gathered from reports and group
output from the SyC AAL meetings in November 2015 (Tokyo), April 2016 (Wellington), October
2016 (Frankfurt), April 2017 (Beijing), September 2017 (Cleveland), December 2017
(Eindhoven), May 2018 (Tokyo), October 2018 (Seoul), June 2019 (Frankfurt) and October 2019
(Shanghai), as well as information obtained during various web meetings.
Experts from liaison organizations and the following national committees have contributed: CA,
CH, CN, DE, GB, IN, JP, KR, NL, NZ, SE, US.
The target audience for this document includes the following stakeholders who have an interest
in the AAL system:
• AAL users and service provider personnel who can learn about AAL user needs and how to
operate AAL systems;
• consumer electronics and information and communication technology device manufacturers
who want to understand AAL devices and interface and interoperability requirements;
• stakeholders who are interested in the usability, accessibility and performance of the AAL
system as well as AAL operators who need to understand the system requirements;
• regulators who are responsible for developing and supervising AAL and related regulations.

ACTIVE ASSISTED LIVING (AAL) REFERENCE ARCHITECTURE AND
ARCHITECTURE MODEL –
Part 2: Architecture model
1 Scope
This document specifies the AAL architecture model.
This document defines concepts and introduces terminology. IEC 63240-1 provides generic
rules for designers of AAL systems and services with the aim to facilitate systems design and
enable interoperability between components. This document provides a framework to analyse
use cases on a common view and terminology, which is a foundation for communication to
discuss the interoperability of the components of the AAL system. This document allows for the
mapping of defined AAL use cases and supports the identification of interoperability issues and
gap analysis of the standards.
This document also identifies safety, security, privacy, and other requirements for AAL systems
such as usability, accessibility, and trustworthiness (reliability, resilience).
