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 prEN 17240. This deliverable therefore adapts and revises Conformance Test Procedures (CTPs) from EN 16454 and prEN 17240 for hybrid circuit switched/packet switched network environments. This document complements EN 16454 and prEN 17240 and provides a suite of conformance tests for IVS equipment, MNOs and PSAPs, required to ensure and demonstrate compliance with EN 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.
