Conformity Assessment Schema

9. EENA Conference 2018 | 112 Portugal eCall Implementation and Open Issues
The Suitability for Use eCall tests are translated through five rated Key Performance Indicators (KPIs) that are
defined in the session 7.2 of the document “I_HeERO Milestone 9 Conformance Assessment documentation -
part 2”.
The eCall tests were executed using certified IVS’s. Each IVS device was triggering the needed electronic
transactions for stimulating the generation and the logging of the relevant data for calculating the KPIs that assess and
rate the behavior of the PSAP under test. According to the reference document there are three possible ratings that
each KPI can get: “High Quality”, “Standard” and “Basic”.
• Success rate of completed eCall using 112
• Success rate of call-backs
• Success rate of correct MSDs
• Success rate of correct re-transmitted MSDs
• Duration of voice channel blocking
KPI’s

Issue #1- Ghost Calls

The most common audit finding was the mobile handsets sending all bits set to "1"
Trace Example – Incorrect eCall
All bits are
set to 1

Configuration of the PSAP Modem in PUSH-mode
- In this case we have near 5 seconds of silence
during the call while the PSAP tries to detect
the IVS initiation signal.

Recommendations
• Commit official entities with decision-making responsibilities;
• Use a reliable and knowledge network (I_HeERO role was a paramount importance);
• Slice the eCall implementation, to isolate the tasks complexity;
• Assign a work consortium team with the right skills to deal with each part of the eCall
chain;
• eCall is not an out of the box solution!!!
• Needs Tests, tests, tests …
• Share the issues, the solutions and the results, with all stakeholders.
