Intelligent transport systems - ESafety - ECall end to end conformance testing for eCall HLAP in hybrid circuit switched/packet switched network environments

Scope

This document describes the key actors in the eCall chain of service provision in hybrid circuit switched/packet switched network
environments as:
1) In-Vehicle System (IVS)/vehicle,
2) Mobile Network Operator (MNO),
3) Public Safety Answering Point (PSAP),
and to provide conformance tests for actor groups 1) – 3).
NOTE 1 Conformance tests are not appropriate nor required for vehicle occupants, although they are the recipient of the service.
NOTE 2 Third party eCall systems (TPS-eCall) are not within the scope of this deliverable. This is because the core TPS-eCall
standard (EN 16102) does not specify the communications link between the vehicle and the TPS service provider.
NOTE 3 These conformance tests are partly based on the appropriate conformance tests from EN 16454 and CEN/prEN 17240.
This deliverable therefore adapts and revises Conformance Test Protocols (CTP) from EN 16454 and CEN/prEN 17240 for hybrid circuit switched/packet switched network environments.
This document complements EN 16454 and CEN/prEN 17240 and provides a suite of conformance tests for IVS equipment, MNOs and PSAPs, required to ensure and demonstrate compliance with CEN/prEN 17905.
The scope covers conformance testing of new engineering developments, products and systems, and does not imply testing associated with individual installations in vehicles or locations.
