Scope

This document defines the key actors in the eCall chain of service provision using IMS over packet switched networks (such as LTE/4G) as:

1) In-vehicle system (3.20) (IVS)/vehicle,

2) Mobile network Operator (MNO),

3) Public safety answering point (3.27) (PSAP), and to provide conformance tests for actor groups 1) - 3).

NOTE 1 Conformance tests are not appropriate nor required for vehicle occupants (3.36), 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 (3.32) standard (EN 16102) does not specify the communications link between the vehicle and the TPS service provider (3.29).

NOTE 3 These conformance tests are based an the appropriate conformance tests from EN 16454 which was published before Internet Protocol multimedia Systems (IMS) packet switched networks were available. This deliverable therefore replicates the appropriate tests from EN 16454 (and acknowledge their source); adapt and revise Conformance Test Protocols (CTP) from EN 16454 to an IMS paradigm; or provide new additional tests that are required for the IMS paradigm. Some 14 112-eCall (Pan European eCall) tests provided in EN 16454 are specific to GSM/UMTS circuit switched communications and not appropriate for the IMS paradigm and are therefore excluded from this deliverable.

This document therefore provides a suite of ALL conformance tests for IVS equipment, MNO's, and PSAPS, required to ensure and demonstrate compliance to CEN/TS 17184.

NOTE 4 Because in the event of non-viability or non-existence of an IMS supporting network at any particular time/location, IMS-eCall systems revert to CS networked eCall systems eCall via GSM/UMTS, IVS and PSAPs need to support, and prove compliance to both IMS and CS switched networks. The Scope covers conformance testing (and approval) of new engineering developments, products and systems, and does not imply testing associated with individual installations in vehicles or locations

Purpose

CEN TS 17240:2018 needs to be updated, because the current revision of CEN TS 17184. EN 15722:2020 mandates 3 positions (current and two delta positions) in the MSD, but for this new requirement, no test case is defined in TS 17240:2018.

This gap and others gaps exposed by the update of 17184 should be closed in a revision of EN 17240.

The two documents need to be upgraded to EN status as they are likely to be referenced in new eu regulations

Other aspects of this upgrade into an EN are:

1. Definition of missing pass conditions

2. Correction of test objectives

3. Update of references (due to revision of CEN TS 17184)

4. MSD transfer during PSAP callback

5. References to ETSI TS 136 523-1, ETSI TS 134 229-1, ETSI TS 134 229-5 and ETSI TS 138 523-1 to be added/updated

6. Optional MSD transfer via in-band modem during VoIMS call

7. Verification of IPv4 and IPv6 support
