Overview
ISO/IEC TR 30148:2019 - Internet of Things (IoT) - Technical requirements and application of sensor network for wireless gas meters - is a Technical Report that defines the network structure and application protocol for sensor networks used with wireless gas meters. The report describes layered architecture (application layer and application sub‑layer), message formats, communication models (request/response, publish/subscribe, report source/sink), and a security overview to support reliable, scalable IoT gas metering deployments.
Keywords: ISO/IEC TR 30148:2019, IoT, wireless gas meters, sensor network, application protocol, network structure, application sub-layer, security.
Key Topics and Technical Requirements
- Network structure: Defines functional entities (wireless gas meters, access points, acquisitors, gateways, handheld devices, servers) and a three‑level architecture connecting meter networks to internet/mobile networks and cloud/data centers.
- Application layer (AL) & Application sub‑layer (ASL): Specifies AL functions for data processing and management and ASL services that provide link, connect, release and data transmission primitives between entities.
- Communication models: Covers interaction models such as Request/Response (R/R), Publisher/Subscriber (P/S), and Report Source/Sink (R/S) for different use cases (on‑demand reads, event notifications, telemetry).
- Message formats and primitives: Describes APDU/PDUs, message control fields, operation/command codes, and parameters for LINK, CONNECT, RELEASE and DATA primitives to ensure interoperable messaging between devices and servers.
- Device management & user application processes: Defines User Application Objects (UAO), User Application Processes (UAP), and Device Management Application Processes (DMAP) for provisioning, firmware updates and status monitoring.
- Security considerations: Annex A provides a security framework with scenario analysis and security services recommendations to protect data integrity, confidentiality and availability in IoT gas metering systems.
Practical Applications and Users
Who uses this standard:
- Gas utilities and energy providers implementing automated meter reading and remote monitoring.
- Meter manufacturers designing wireless gas meters and firmware to interoperate with ASL/AL protocols.
- System integrators and IoT solution providers building end‑to‑end metering networks, gateways and cloud services.
- Regulatory bodies and procurement teams specifying interoperability, data models and security expectations.
Practical benefits:
- Enables real‑time data collection, dynamic pricing, event alarms and energy management.
- Reduces manual reading costs and improves billing accuracy.
- Supports scalable, interoperable deployments across access points, gateways and cloud backends.
