  2. ETSI TC-ITS WG1, Application and Services • Proposed NWIP -- Co-operative Awareness Application Specification • Use Cases • Slow vehicle overtaking • Motorcycle approaching • Stationary vehicle (breakdown / accident) • Bad weather condition / traffic jam • Road work • Emergency vehicle approaching • Application • Information broadcasted by an ITS-S and received by all local ITS S about a road hazard which does not present a collision risk (toofar from the receiving vehicles). Just an info to the driver

  3. WG1 (continued) • Other NWIPs • Electric vehicle charging spot notification application specification • Positioning and time management • Intersection Collision Risk Warning Application Specification • Longitudinal Collision Risk Warning Application Specification • TS 102 890 part 2: Services Announcement • Development of ASN.1 description of the SAM • Adjustment to ISO 24102 (Services List) + CPID

  5. WG1 (Continued) • CEN Liaison Report Topics • FVCMS: Forward Vehicle Collision Mitigation Systems (WD for ADAS extended to V2V) Driver Assistance and Emergency Braking • FVCWS: Forward Vehicle Collision Warning Systems (FDIS for ADAS extended to V2V) Driver Assistance • CIWS : Co-operative Intersection signal information and violation Warning Systems (ISO / NP 26684)

  6. ETSI TC-ITS WG2, Architecture • WG2 has 31 work items at different stages of development • Dieter Smely presents the last report of STF 395, focusing on alternative methods to achieve coexistence between CEN DSRC and ITS-G5 • For ETSI, two actions resulted: • The need for a common cross-layer meeting to discuss ITS-AID • The responsibility to decide on a "Registration Authority" is proposed to be in the EU/US task force. Resolution needed in TC-ITS • EU Mandate Roadmap schedule was determined to be “too ambitious,” meeting schedule and expert resources inadequate

  7. ETSI TC-ITS WG3, Transport and Network • Proposed liaison with IETF MEXT • T. Ernst, proposed as liaison officer, editor in ISO TC204 and ETSI TC-ITS WG3 of IPv6 drafts • Harmonization agreement in progress with technical discussion to agree on compatibility and interoperability between ETSI and ISO and ISO/CEN under the Vienna Agreement • To what extent does IPv6 used in IEEE Std 1609.3, ETSI and TC204 “upper layer” protocols need to be compatible? • How will Mobile Extension to IPv6 (MEXT) affect the work in IEEE 1609 WG?

  8. WG3 (continued) • TC 204 Liaison Report • T. Ernst: TC 204 WG16 has adopted two new WIs: IPv6 optimization (routing, handoff) and IPv6 security • Both complement ISO 21210 • There is also a new WI related to Geo-Networking, which is focused on aspects the Geo-Networking in the CALM architecture (such as SAPs)

  19. Observations (1) • Geo-networking using Basic Transport Protocol (BTP) over IPv6 is different approach to WSM and UDP/TCP over IPv6 in 1609.3 a barrier to simple harmonization • Security approach and technical considerations are well coordinated with same expert involved in ETSI, ISO, SAE, and IEEE • Local Dynamic Map (LDM) approach in Geo-Networking is a barrier to simple harmonization • Time synchronization was not discussed with LDM; is a work item in WG1 • Detailed technical expert input to the architecture and lower layer working groups • CAM and DENM message set development following CVIS and C2C-CC requirements differs in approach to that of SAE J2735 – WG1 Chair noted a need to coordinate with SAE, but lacks an expert contact to start discussions

  20. Observations (2) • ITS Station Architecture, adaptation of the ISO TC204 CALM Architecture is on its way to approval as European Norm (EN 302 665 and differs significantly in upper layer structure compared to 1609.0, with multi-PHY standards • Security architecture in development and not addressed in 1609.2 or 1609.0 project scopes • 5.9GHz WAVE Mode profile with EU regulatory requirements has not been converted to EN302 663 format for submission as an EN; harmonization with 802.11 maintenance draft will be needed in 2011-2012 • ISO and ETSI have appointed liaison to IETF to work on Mobile EXT to IPv6 • Concept of “HAI” portable device protocol and layer services in communication stack needs expert coordination • Advantageous to find more experts to participate in ETSI
