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.

FOREWORD
1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have
established a joint technical committee, ISO/IEC JTC 1.
2) The formal decisions or agreements of IEC and ISO 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 and ISO member bodies.
3) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted
by IEC National Committees and ISO member bodies in that sense. While all reasonable efforts are made to
ensure that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO 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 and ISO member bodies undertake to
apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and
regional publications. Any divergence between any ISO, IEC or ISO/IEC publication and the corresponding
national or regional publication should be clearly indicated in the latter.
5) ISO and IEC do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. ISO or IEC are not responsible
for any services carried out by independent certification bodies.
