2. Sub Working Group 2 Content
Identification of Requirements related to Facilities and Networking layer
CAM, DENM, GN
Requirements defined based on:
C2C Basic System Standards Profile
ETSI Base Specifications
Goal is to ensure protocol conformance
Resulting Protocol Conformance Tests
Provided in Human readable format
Implemented in TTCN-3
WG Arch

3. Status Update Sub Working Group 2
Current Status
Requirements sheets complete (version v25)
First release of Test cases complete V1.0.0

7. Challenges Mapping of ETSI requirements to C2C BSSP requirements
investigation on what is redundant and where are new test cases to be developed
Verify the new developed and implemented test cases
Verification events
Test cases related to traces, path history, path points and message generation rules missing GNSS replay functionality in first set of test cases
External GNSS simulator to replay geolocation and timing data
WG-CA – SG 2 Status

8. (Helmond ETSI Plugtest, March 2015)
Verification event
Goal is to verify the correct implementation of the test cases
Companies invited to verify the test cases with their equipment implementation
Depending on results and analysis test cases:
to be reworked
accepted
Status today
New version including
GNSS replayer
Initial

1st verification event
(Helmond ETSI Plugtest, March 2015)
2nd verification event
(CETECOM, Q4/2015)
3rd verification event
(final release)
WG-CA – SG 2 Status

9. Results of 1st verification event (1/2)
Precondition:
29 test case written by external companies (FSCOM & TestingTech)
Test cases verified in verification event
Verification done by 6 manufacturers
Outcome:
Overall pass rate was around 55% (16 of 29 tests)
Investigation on failed test cases showed some test script implementation erros
Some test cases need to be reworked
Next steps:
Test cases reworked and optimized
Test cases to be revalidated in 2nd verification event
