Challenges with eCall
•
•
•
•
New standards
No existing reference system
No performance requirements
No approval / certification requirements
First ITS application
telecommunication meets
automotive
Definitions
•
Conformance Tests
Testing to determine whether a product or system meets specified standard
•
Performance Tests
Testing to determine whether a product or system fulfills specified performance
criteria
•
Interoperability Tests
Testing to determine whether a product or system can exchange information based
on a standard with another product or system
•
Type approval (automotive)
Third party approval ensure that the products are in full compliance with the relevant
standards and regulations. Each Member State is required to appoint an Approval
Authority to issue the approvals, and a Technical Service to carry out the testing
•
Voluntary certification (telecom)
Certification by GCF a not-for-profit private company to enable and promote
certification with accredited laboratories for testing

•
Pre-deployment projects
January 2011 to December 2014
15 Pilot Sites
€ 8 million EC funding available
Total budget € 16 million
82 Partners
5 additional sites upgrading at their own
expense.

Conformance Requirements
• Requirements for conformance were early available
• Standards describing end to end conformance tests
for
– eCall establishment (ETSI) in the mobile network
– Data exchange (CEN) on application level
IVS

PSAP

Conformance
•
•
•
•
•
Development of IVS and PSAP based on CEN protocols
How to validate correctness
Typically a complementing “test counter part” developed in parallel
However same understanding of protocols and same engineers
No reference system available except
Test centre by OECON, certified by NavCert

eCall Simulator
•
•
•
•
•
•
Simulation of IVS and PSAP - End to end testing, no mobile network simulation
Conform to applicable standards
based on standardized TTCN-3 technology
Textual and graphical logging
High reusability and easy execution of predefined tests
Generation of test reports
