Sub Working Group 2 Protocols & Messages Car2Car Forum Mainz, 04.11.2015 Sub Working Group 2 Protocols & Messages Presented by Jörn Edlich, CETECOM Sebastian Müller, ETSI

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 17.05.2019 WG Arch

Status Update Sub Working Group 2 Current Status Requirements sheets complete (version v25) First release of Test cases complete V1.0.0 Issues on BSSP 2014-1-31v1.0.4 reported to Bugzilla 1st verification event executed in March 2015 at Plugtest Helmond GNSS scenarios and replay functionality implemented in all test cases 2nd verficiation event planned for November 2015 5/17/2019 WG-CA – SG 2 Status

Test Cases and Requirements 69 testable requirements identified overall 13 CAM, 26 DENM, 30 Network and Transport Layer 94 Test cases overall 28 Prio 1 (12 CAM + 14 DENM + 2 GN) (new developed test cases) 53 Prio 2 (13 CAM + 23 DENM + 17 GN) (ETSI mapped test cases) 13 Prio 3 (13 GN) (ETSI req. , no correlating C2C req. available yet but essential protocol features) mandatory for certification 5/17/2019 WG-CA – SG 2 Status

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 17.05.2019 WG-CA – SG 2 Status

(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 implementation stable version (no GNSS replayer) bugzilla Resulution implemented Final version bug fixes bug fixes bug fixes Bug report Bug report Bug report 1st verification event (Helmond ETSI Plugtest, March 2015) 2nd verification event (CETECOM, Q4/2015) 3rd verification event (final release) 17.05.2019 WG-CA – SG 2 Status

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 5/17/2019 WG-CA – SG 2 Status

Results of 1st verification event (2/2) 5/17/2019 WG-CA – SG 2 Status

Open points / next steps Providing Input for Working Group Compliance Assessment Whitepaper Implementation of bugzilla resolutions (requirements update) Planning (final) verification event for new developed test cases verification of Test System and Test Cases with GNSS replayer features (test cases available since end of October) Finalizing the Scope of Compliance Assessment 5/17/2019 WG-CA – SG 2 Status

5th C-ITS Plugtest 2016 Date: 7 – 18 November 2016 Location and Host: TBD Organized with ERTICO, Supported by EC Test Infrastructure extension with Traffic Management components Based on Central System, Traffic Controller and RSUs Support from Siemens. Any other suppliers are welcome Scope End-to-end Interop Tests SPAT, MAP, IVI, CAM, GN Selected use cases from TR 102 638 Release 1 revision and EC projects PKI Trust Center (Certificate Management) DCC tests (under study) Mitigation CEN DSRC and ITS G5 Conformance Car Drive Tests 17.05.2019 WG-CA – SG 2 Status
