ISO/IEC 14543-5-9:2017

Overview

ISO/IEC 14543-5-9:2017 defines the Remote Access Service Platform (IRSP) for Intelligent Grouping and Resource Sharing (IGRS) in Home Electronic Systems (HES) Class 2 and Class 3. The standard specifies the basic functionalities, module structures and server interfaces of an IRSP, and it standardizes service interaction flows plus request/response message formats used for remote access to home devices and services.

Key topics and technical requirements

• IRSP architecture and modules: Describes the overall platform layout and the roles of core servers (Account Server, Message Server, Application Server and External Application Server).
• Server types and responsibilities: Defines the functions of each server type and how they collaborate within the IRSP.
• Message exchange models: Specifies message flows between servers including intra-platform and inter-platform exchanges (e.g., message server ↔ application server, application server ↔ application server).
• Service interaction flows: Standardized sequences for common operations such as account registration, modification, deletion, device verification code reset, and message push/pull.
• Request/response formats and status codes: Defines the structure and expected response status code sets for registration, modification, deletion and messaging operations (tables of response codes and contents are provided).
• Interfaces and protocols: Clarifies interfaces among IRSP components; references to the broader IGRS remote access core protocol (see ISO/IEC 14543-5-8) and core networking foundations (TCP/IP, HTTP as in related parts) are part of the series.
• Security considerations: Addresses security requirements relevant to IRSP operation, authentication and safe message exchanges.
• Conformance and testability: Includes conformance clauses to guide implementers and test labs.

Applications and who uses the standard

ISO/IEC 14543-5-9 is intended for professionals and organizations building or integrating remote access services for smart homes:

• Device and platform manufacturers implementing IGRS-compliant HES Class 2/3 devices.
• Cloud and service providers deploying IRSPs or offering remote access/back-end services for home devices.
• System integrators and solution architects designing interoperable remote access solutions.
• Security architects and QA/test labs validating message formats, status codes and conformance with IGRS RA requirements.
• Standards engineers and protocol developers mapping application servers and message servers to standard interfaces.
