Full title and description

BS EN 17240:2024 — Intelligent transport systems. ESafety. ECall end to end conformance testing for IMS packet switched based systems. This European standard specifies conformance test protocols and test case packages to validate end-to-end eCall functionality over IP Multimedia Subsystem (IMS) packet‑switched networks, addressing next‑generation (NG) eCall operation on LTE/4G and 5G networks.

Abstract

This standard defines the conformance testing framework, naming and structure of Conformance Test Packages (CTPs), state‑transition tests, timers and test procedures for In‑Vehicle Systems (IVS), Mobile Network Operators (MNOs) and Public Safety Answering Points (PSAPs) when eCall is carried over IMS (packet switched) networks. It replaces the earlier circuit‑switched conformance approach and aligns IMS eCall testing with relevant ETSI and CEN normative references.

Scope

EN 17240:2024 specifies end‑to‑end conformance testing for eCall services that use IMS packet‑switched communications. The scope covers test architecture, roles and responsibilities for the system under test (IVS, MNO, PSAP/TPSP), conformance test procedures (including accelerated test procedures), CTP structure and naming, IMS‑specific timers and signaling behavior, state transition tests and interoperability checks with referenced ETSI IMS specifications. It is intended to support migration from circuit‑switched eCall to IMS/packet‑switched NG eCall.

Key topics and requirements

• Conformance test framework and classification of testing (IVS, MNO, PSAP role‑based test sets).
• Definition and structure of Conformance Test Packages (CTPs) and CTP naming conventions.
• State transition conformance tests and test objectives for IMS‑based eCall transactions.
• IMS signaling and timer requirements relevant to eCall (SIP/IMS behavior aligned with ETSI specifications).
• Accelerated test procedures for laboratory and factory verification (including IVS and MNO accelerated tests).
• Test data sets and mandatory test cases to validate MSD delivery, emergency call setup and media handling over IMS.
• References and alignment with predecessor circuit‑switched conformance tests (EN 16454) and other eCall HLAP/H LAP/IMS system requirements (e.g., EN 16062, EN 17184).

Typical use and users

Used by automotive OEMs, telematics module and IVS suppliers, Tier‑1 integrators, mobile network operators, PSAP/TPSP test teams, independent test laboratories and certification bodies to demonstrate conformance of eCall implementations to IMS‑based eCall requirements. Test equipment and test solution vendors use this standard to develop test suites and verification tools for NG eCall deployments.

Related standards

Key related documents and predecessors include PD CEN/TS 17240:2018 (replaced), EN 16454 (circuit‑switched eCall conformance tests), EN 16062 (HLAP), EN 17184 (eCall HLAP‑IMS), EN 16072 (operating requirements), and various ETSI IMS technical specifications (e.g., ETSI TS 136 523, TS 138 523, TS 134 229) which are normative or informative references for signaling and IMS behavior. The EN 17240 suite sits within the broader CEN eCall/ESafety family of standards.

FAQ

Q: What is this standard?

A: EN 17240:2024 is a European conformance testing standard for eCall when carried over IMS packet‑switched mobile networks; as adopted nationally it is published as BS EN 17240:2024 for the UK.

Q: What does it cover?

A: It covers end‑to‑end conformance test definitions, test case packages, state transition tests, timer and signaling requirements, and accelerated laboratory procedures for IVS, MNO and PSAP elements involved in IMS‑based eCall.

Q: Who typically uses it?

A: Automotive manufacturers, telematics/IVS suppliers, network operators, PSAPs/TPSPs, test labs, certification bodies and test equipment vendors developing or verifying NG eCall implementations use the standard.

Q: Is it current or superseded?

A: It is current. EN 17240:2024 was published in December 2024 and national adoptions (BS EN and other national versions) have been issued/endorsed in 2025; it replaces the earlier technical specification PD CEN/TS 17240:2018 and adapts circuit‑switched conformance approaches (EN 16454) for IMS.

Q: Is it part of a series?

A: Yes — it forms part of the CEN/CENELEC eCall / ESafety family of documents and references related EN and ETSI specifications (for example EN 16062, EN 16072, EN 16454, EN 17184 and relevant ETSI TS documents for IMS signaling).

Q: What are the key keywords?

A: eCall, NG eCall, IMS, conformance testing, IVS, MSD, PSAP, MNO, CTP, ESafety.
