Overview
ISO 24101-2:2010 - part of the CALM (Communications Access for Land Mobiles) family - specifies a standardized conformance test for Application Management (AM) in Intelligent Transport Systems (ITS). Its purpose is to define the test system, test cases, test conditions, test procedures and expected test results to verify that an AM implementation (software installed on On‑Board Equipment (OBE) or Wireless Access Equipment (WAE)) conforms to the requirements of ISO 24101-1:2008. Note: accreditation and formal certification processes are outside the scope of this part.
Key Topics and Requirements
- Scope and methodology: Test approach follows ISO/IEC 9646 principles and targets AM functions: install, modify and uninstall applications on deployed ITS equipment.
- Test system architecture: Defines roles and entities such as the Equipment Under Test (EUT), test installer, test operator, verification means and communication station used to exercise and observe AM behavior.
- Test cases: Organized into basic tests and advanced tests (see Annex A and Annex B). Tests validate normal operation and error handling during application lifecycle operations.
- Test conditions: Prescribed preconditions and operational settings (test applications, security credentials, manager certificates, common files, scheduling) to ensure repeatable conformance testing.
- Test procedures and notation: Step‑by‑step procedures, commands and expected states to produce pass/fail verdicts; includes command lists (Annex C).
- Verification & instrumentation: Use of verification means (debugger, emulator, PC) to confirm execution results, read/write the Application Management Table (AMT), set clocks and simulate faults.
- Test documentation: Requires Implementation Conformance Statement (ICS), Implementation eXtra Information for Testing (IXIT) and a formal test report (proforma annexes D and E).
- Security and authentication: Tests include operator authentication and manager certificate use for access control (as part of test conditions).
Applications and Who Uses It
ISO 24101-2 is practical for:
- ITS software developers implementing application management on vehicles and roadside units.
- Vehicle OEMs and WAE manufacturers validating AM function on OBEs/WAEs.
- Test laboratories and system integrators conducting AM conformance tests and interoperability trials.
- Regulators and procurement teams specifying compliance test requirements for ITS deployments.
Benefits include improved interoperability, reliable over‑the‑air application updates, and standardized verification of security controls (operator auth, certificates).
