ISO 15638-10:2017

Overview - ISO 15638-10:2017 (TARV) eCall / Emergency Messaging System

ISO 15638-10:2017 is part of the ISO 15638 suite for intelligent transport systems (ITS) and defines the Emergency Messaging System / eCall application using the TARV (Framework for cooperative telematics applications for regulated commercial freight vehicles) architecture. The standard specifies the form, content and access methods for emergency messaging data (including the Minimum Set of Data - MSD) and provides common communications and data-exchange requirements that a regulator may require or adopt. It builds on the TARV framework and communications methodology specified in ISO 15638‑1 to 6.

Key topics and technical requirements

• Service definition and scope: High-level definition of the EMS/eCall service, expected service elements and responsibilities (jurisdiction, approval authority, service provider, user).
• Data specification: Structure and content requirements for the MSD, HGV eCall dataset and optional additional data (schemas), including naming, content and quality expectations.
• Sequence and concept of operations: Detailed operational flows for TARV eCall and TARV EMS (triggers, call establishment, data retrieval, emergency responder contact, operator notification).
• Quality of service (QoS): Performance, reliability and testing provisions specific to EMS/eCall services.
• Interoperability & communications: Common communications and data exchange aspects to enable consistent implementations across service providers and jurisdictions.
• Security & access control: Information security, data access control policy and rules for provisioning/retrieval of emergency data.
• Conformance and approval: Requirements for IVS (in-vehicle systems) approval, service provider auditing, software quality systems and test/marking obligations.
• Operational governance: Roles and responsibilities, jurisdictional choices and constraints (national decisions on which services are regulated).

Practical applications and users

ISO 15638-10:2017 is intended for organizations implementing emergency messaging/eCall solutions for regulated commercial freight vehicles (e.g., HGVs). Typical users include:

• Vehicle OEMs and telematics hardware suppliers (IVS integrators)
• Telematics service providers and emergency call centers (PSAPs)
• Regulatory bodies and approval authorities designing jurisdictional eCall requirements
• Fleet operators and logistic companies seeking compliant emergency messaging capabilities
• System integrators, testers and auditors validating QoS, security and conformance

Related standards

• ISO 15638 series (Parts 1–6 framework and communications)
• EN 15722 and EN/TS 16405 (referenced updates for MSD and optional data alignment)

ISO 15638-10:2017 enables standardized, interoperable eCall/emergency messaging for regulated freight vehicles - improving emergency response, data consistency and cross-jurisdictional deployment of cooperative telematics.
