ISO 24102-2:2018

Overview

ISO 24102-2:2018 defines the remote management component of Intelligent Transport Systems (ITS) station management. It specifies the Remote ITS Station Management Protocol (RSMP) - the protocol data units (PDUs) and procedures used to remotely manage ITS station communication units (ITS‑SCUs) in line with the ITS station reference architecture (ISO 21217). The standard distinguishes managed entities (management clients) from managing entities (management servers) and delivers normative artifacts such as ASN.1 modules and conformance/test guidance.

Keywords: ITS station management, RSMP, ITS‑SCU, remote management, ITS station, ASN.1, FSAP

Key technical topics and requirements

• Scope and architecture
  • Conformance with the ITS station reference architecture (ISO 21217).
  • Remote management is applied to an ITS station communication unit (ITS‑SCU) within an ITS station unit (ITS‑SU).
• Remote ITS Station Management Protocol (RSMP)
  • Specification of PDUs and procedures for remote configuration, update, installation/uninstallation, notification and retrieval of management information.
  • Distinction between management clients (RMC) and management servers (RMS).
• Protocol components and services
  • Service primitive functions and SAPs (e.g., MF‑SAP, SF‑SAP) for transmission, reception and security-related handling of RSMP messages.
  • Session management procedures: session initiation (server‑ or client‑initiated), session identifiers, security context and session closure (active closure, timeout).
• Management activities covered
  • Firmware updates, installation/maintenance of ITS‑S application processes and communication protocols, configuration management, logging and alarm retrieval.
• Data and encoding
  • ASN.1 modules provided (normative annex) and PER encoding reference (ISO/IEC 8825‑2).
• Conformance and testing
  • Clauses for conformance declaration and test methods, plus an Implementation Conformance Statement (ICS) proforma.
• Related mechanisms
  • Fast Service Advertisement Protocol (FSAP) usage details and communication service parameter recommendations (informative annex).

Practical applications and users

ISO 24102-2 is intended for organizations that develop, deploy or operate ITS communications and management systems:

• ITS integrators and system architects designing station management solutions.
• Vehicle and roadside equipment manufacturers implementing ITS‑SCU remote management.
• Infrastructure operators (traffic authorities, tolling operators) needing remote configuration and firmware updates.
• Software developers of management servers/clients and RSMP implementations.
• Test laboratories and certification bodies performing conformance testing.

Practical uses include remote firmware provisioning, remote configuration of access-layer and application parameters, log retrieval and alarm handling across vehicle-to-infrastructure (V2I) and infrastructure networks.

Related standards

• ISO 21217 (ITS station architecture)
• ISO 24102-1 (Local management)
• ISO 24102-3 (Service access points)
• ISO TS 16460, ISO 17419, ISO/IEC 8825-2

ISO 24102-2 provides the protocol-level foundation for secure, standardized remote management of ITS station communication units, enabling interoperable maintenance and lifecycle management across ITS deployments.
