Full title and description

St ISO IEC 15045-4-2-2024 — Information technology — Home Electronic System (HES) gateway — Part 4-2: Structure — Simple gateway. This part defines the structure and minimum requirements for the "simple" HES gateway physical class used to connect home-area networks and wide-area networks within the Home Electronic System framework.

Abstract

This document specifies the simple HES gateway, one of the set of physical classes introduced in ISO/IEC 15045-1. It describes the expected structure, primary modules (e.g., HAN and WAN interfaces), and the baseline behaviours required to ensure interoperability and safe operation of a simple gateway in home and building electronic systems.

Scope

Defines the structure and baseline requirements for the simple HES gateway physical class used in Home Electronic Systems. The standard applies to gateways intended to provide straightforward HAN-to-WAN interconnection with a minimal set of modules and services, and it references the broader HES gateway architecture and modularity defined in earlier parts of the 15045 series. It is intended to enable interoperability, predictable behaviour, and safe/basic protection of user privacy and data in simple gateway deployments.

Key topics and requirements

• Definition of the "simple gateway" physical class and its intended role in HES architectures.
• Structure and required modules (typical minimum: HAN interface module(s), WAN interface module, basic service/management functions).
• Interface baseline behaviours to ensure predictable message exchange between HAN and WAN domains.
• Interoperability and conformance expectations relative to other 15045 parts (module interfaces, binding maps, service modules).
• Foundational guidance on safety, privacy and security considerations appropriate to a simple gateway (references to related HES guidance where detailed controls are specified).

Typical use and users

Used by gateway device manufacturers, system integrators, firmware/software developers for residential and small-building gateways, conformity/test laboratories, procurement teams specifying HES gateway requirements, and standards developers or national bodies implementing HES-related regulations. It is intended for projects where a straightforward HAN–WAN gateway solution (limited modular complexity) is required.

Related standards

Key related documents in the HES and gateway family include: ISO/IEC 15045-1:2004 (Residential gateway model for HES); ISO/IEC 15045-2:2012 (Modularity and protocol); ISO/IEC 15045-4-1:2024 (Structural class and module requirements); guidance and privacy/safety documents in the 15045/15067 family and other HES interoperability guidelines. These parts together define the architecture, module requirements and behaviour across simple, complex integral and complex modular gateway classes.

FAQ

Q: What is this standard?

A: ISO/IEC 15045-4-2:2024 is the "Structure — Simple gateway" part of the HES gateway standard series; it defines the structural definition and minimum requirements for a simple Home Electronic System gateway.

Q: What does it cover?

A: It covers the structure, required modules (HAN/WAN interfaces and basic service/management functions), expected interface behaviours and baseline interoperability and safety/privacy considerations for a simple gateway class within the HES framework. It does not replace more detailed module or security guidance found in companion parts of the 15045 series.

Q: Who typically uses it?

A: Manufacturers of residential gateways, firmware and software developers, integrators, test and conformity labs, procurement/specification teams, and standards organizations involved with home/building electronic systems.

Q: Is it current or superseded?

A: The standard was published in December 2024 and is listed as published/active in ISO/IEC catalogues and webstores. No public superseding or withdrawal notice was identified at the time of this summary (checked March 2, 2026); IEC/ISO product entries indicate stability into 2029. Users should verify the status with national bodies or ISO/IEC catalogues if they need the absolute current legal/adoption status.

Q: Is it part of a series?

A: Yes — it is part of the ISO/IEC 15045 series for HES gateways (see especially Parts 1 and 2 for the overall model and modularity, and Part 4-1 and other 4‑x parts for structural classes and other gateway types).

Q: What are the key keywords?

A: HES gateway, simple gateway, residential gateway, HAN, WAN, interoperability, module requirements, ISO/IEC JTC 1/SC 25.
