Overview
IEC 63240-1:2020 - Active assisted living (AAL) reference architecture - Part 1: Reference architecture - specifies a high-level reference architecture for Active Assisted Living systems. The standard defines core concepts and terminology (for example AAL device, AAL gateway, AAL platform/backend system, AAL application, and AAL information system) and provides generic design rules to facilitate system design and enable interoperability between AAL components. It also identifies cross-cutting requirements such as safety, security, privacy, usability, accessibility, and overall trustworthiness (reliability, resilience).
Key topics and requirements
- Concepts & terminology: Standardizes vocabulary used across AAL solutions to improve clarity among designers, manufacturers and service providers.
- Reference architecture description: Conceptual layers and interfaces that guide how devices, gateways, backend systems and applications interconnect.
- Interoperability rules: Generic guidance to support consistent interfaces and data exchange between heterogeneous AAL components and networks (LAN, WAN, Internet).
- Security and privacy requirements: Identification of privacy risks (e.g., monitoring location, health and wellbeing, IoT data exposure), security process considerations, and the potential use of AI in cyberthreat contexts.
- Usability & accessibility: Early-stage guidance for embedding user-centered design to meet the needs of diverse AAL users.
- Trustworthiness: Requirements and considerations for reliability and resilience of AAL systems in real-world deployments.
- Relationship to IoT: Explains how AAL systems relate to Internet of Things deployments and implications for design and risk management.
Practical applications
- Designing interoperable smart home and assisted-living ecosystems that integrate sensors, consumer electronics and healthcare endpoints.
- Specifying system architecture for remote monitoring, telecare and wellbeing services.
- Guiding secure data flows between home devices, AAL gateways and backend platforms or external health information systems.
- Informing procurement, system integration and testing criteria for vendors and integrators.
- Supporting regulatory compliance and risk assessment work for privacy and safety in AAL deployments.
Who should use this standard
- AAL system architects and solution designers
- Consumer electronics and ICT device manufacturers
- Service providers and platform operators
- Healthcare and social-care technology integrators
- Regulators, procurement officers and standards implementers
