IEC 63240-2:2020

Overview

IEC 63240-2:2020 - Active Assisted Living (AAL) reference architecture and architecture model (Part 2) specifies the AAL architecture model and terminology. It provides a common framework to analyse AAL use cases, map components (devices, gateways, backend systems), and discuss interoperability. The standard complements IEC 63240-1 (reference architecture) by focusing on the architecture model, concepts and vocabulary that support design, gap analysis and standards harmonization for AAL solutions.

Key topics

• AAL architecture model structure - described as a multi‑axis model (X: levels of assistance, Y: component composition, Z: model and process views) to give a consistent system view.
• Component definitions - clear terms for AAL device, AAL gateway, AAL platform/backend system, AAL application/service, AAL information system and other information systems.
• Layered views and figures - actor (physical) layer, communication layer, information/data model layer, function (service) layer, stakeholder layer and business layer are illustrated to support implementation planning.
• Interoperability and use‑case mapping - framework to map defined AAL use cases to the architecture model, enabling identification of interoperability issues and standards gaps.
• Non‑functional requirements - identifies essential requirements such as safety, security, privacy, usability, accessibility, and trustworthiness (reliability, resilience).
• Relationship to IoT - discusses how AAL relates to IoT technologies while maintaining AAL‑specific terminology and requirements.

Applications

IEC 63240-2 is practical for:

• System architects and designers creating interoperable AAL systems and services.
• Device and consumer electronics manufacturers building AAL devices, gateways or backend components who need standardized terminology and interface considerations.
• Integrators and software developers mapping AAL use cases to system components and identifying interoperability risks.
• Service providers, healthcare organizations and regulators assessing requirements for safety, privacy, accessibility and resilience in AAL deployments.
• Standards bodies and test labs performing gap analysis and aligning other standards with AAL needs.

Who should use this standard

• AAL users and service provider personnel
• Consumer electronics and ICT device manufacturers
• AAL system integrators and operators
• Regulators and policy makers
• Standards developers and testing organizations
