ISO/IEC 14543-5-1:2010 PDF

Overview

ISO/IEC 14543-5-1:2010 defines the application-layer services and core protocol for Intelligent Grouping and Resource Sharing (IGRS) within the Home Electronic System (HES) architecture. The standard targets Class 2 and Class 3 IGRS devices and is designed to enable resource sharing and service collaboration among computers, consumer electronics and communication devices across LANs and PANs - particularly in wireless dynamic networks. It prescribes message formats, device/service descriptions, grouping and discovery mechanisms, session and security handling to support interoperable smart home ecosystems.

Key Topics

• IGRS Core Protocol & Architecture: Application-layer framework and interaction model for IGRS devices, including conformance rules and how the IGRS profile maps to device behavior.
• Device and Service Description: Templates and identifiers for device, service, client and user descriptions to enable consistent discovery and capability exchange.
• Device Grouping & Pipe Management: Mechanisms for forming device groups (peer-to-peer and centralized), creating/unsecure and secure device pipes, trust relationships and group lifecycle (join, dismiss, secession).
• Service Discovery & Advertisement: Multicast and proxy-based discovery methods (specified ISDP in Annex A), service online/offline advertisement, registration and search procedures.
• Session & Resource Sharing: Session setup/teardown conditions, service invocation request/response flows and event notification/subscription models for online/offline events.
• Message Framework & Security: Request/response message structures, secure-device-pipe support with message authentication and encryption options; normative details for secure message handling and status codes.
• Normative Annexes: ISDP (IGRS service discovery protocols) and description document formats (Annex B) for interoperable implementation.

Applications and Who Uses It

Practical use cases:

• Smart home interoperability: Enabling TVs, gateways, sensors, controllers and appliances to discover and share services in a home network.
• IoT device collaboration: Resource sharing among consumer electronics and computing devices in dynamic wireless environments.
• Home automation platforms: Implementing reliable discovery, session management and secure control for automation scenarios.

Typical users:

• Device manufacturers and firmware engineers implementing IGRS-capable products
• Home automation integrators and solution architects
• IoT platform developers and middleware vendors
• Test labs and certification bodies validating conformance to HES/IGRS profiles
