In General• The Term is used randomly in horizontal and vertical system

definitions. No definition is found.

HC in ITS and Automation (CCAM) • European wide the term was introduced in the C-ITS

deployment platform phase 1 report (2016). • ITS Origen: Amsterdam Group Roadmap and Dutch

Rijkswaterstaat Standardisation report (2014).

Hybrid Communication

Complementarity, Interoperability and Coexistence!

C-ITS platform phase 1 report does not provide a clear definition. It only described that it should support

− communication neutrality with initial deployment based on complementary and concurrent operation of at least regular cellular and IEEE802.11p/ITS-G5 communication technologies.

Based on the limited clarification stakeholders developed their own view not necessarily being Interoperability and Backward compatible.

Hybrid Communication

To realize interoperable for CCAM services a common view on Hybrid Communication needs to be established!

The CODECS & EU Commission Initiative4 steps agreed:

• CODECS Workshop: sharing the views May 19th 2017.

• Report including findings, proposed definitions, concept and recommendations.

• C-ITS Platform meeting: Alignment of the results July 10th 2017

• Publication of the agreements and recommendations: CODECS Workshop ITS Hybrid Communication report T4.2.1*

To further improve safety and support traffic automation (CCAM)By increased data exchange with extended internal sensors and exchange between ITS stations.

Key issues:• Information integrity e.g. trust,

quality, validity, security and privacy

• Communication integrity e.g. avai-lability, access possibility, efficiency,so increase Quality of Service (QoS)

• System integrity e.g. Functional Safety, Increase of data exchange

Main objective, to maximized the functional awareness

Maximizing awareness by sharing data with others

• Basic common understanding, to follow the EU Commission neutral multi-communications approach of deploying initially available complementary and interoperable standard cellular 3-4G and ITS-G5 technologies.

• Other technologies are invited to follow and provide complementary services e.g. Higher CoS, to facilitate extended CCAM services.

• Any CCAM solution needs to comply to the Functional Safety requirements (ISO/TS 26262)

• “Hybrid Communication is not a specific architecture nor a system but it’s the recognized identifier representing the collection of functional and technical improvements to realize to satisfy the main objective of Day-2 and beyond CCAM related data exchange.”

• It became a common recognized term and now an European objective.

• Focus: ”To Work together in realizing the identified resolve the HS challenges such that Day-2 deployments can be realized”.

What needs to be addressed for HC in standardisation?

15Pauls Consultancy BV

15

At Architecture and System Management• To evaluate the Functional Safety system requirements and

propose related ITS related standardisation actions

• To evaluate the consequences of the “Extended Vehicle Model” (ACEA) and MEC services to come to the extended ITS architecture and standardisation.

• Evaluate the QoS requirements• To evaluate Multi-Channel

operation, considering several technologies, specify MCO functionalities and standardize the components.

CCAM aspects to address

16Pauls Consultancy BV

16

At Applications and Facilities• Improve message sets to include additional parameters by which

Information integrity e.g. trust, quality, validity, security and privacy can be improved.

• To realize Geolocation accuracy improvement services (started_

• To realize new message sets for VRU, C-ACC & Platooning• To realize advanced awareness services such as Collective

Perception supporting enhanced Active Safety and Integral Safety

• To support the privacy requirements (GDPR)

CCAM aspects to address

17Pauls Consultancy BV

17

At Applications and Facilities• To realize an MCO adaptation Service making use of available

congestion information and known communication needs, as part of the MCO development. Possibly extend and align with the 3GPP open interface.

CCAM aspects to address

18Pauls Consultancy BV

18

At Networking• Enhance Networking to support multiple technologies such

that interoperability and backward compatibility is ensured.• Enhance Networking to facilitate Multi-Channel Operation.

CCAM aspects to address

19Pauls Consultancy BV

19

At Access and Physical• To translate Multi-Channel requirements into Access and

Physical layer requirements and standardisation.• To investigate the coexistence and interoperability

possibilities of different technologies in the same spectrum.

• To evaluate Decentralized Congestion Control methods for MCO and provide solutions for standardisation

CCAM aspects to address

20Pauls Consultancy BV

20

At Security• Develop security extensions to facilitate information

exchange for an enhanced architecture supporting data safety data aggregation and MEC

• Identify Security consequences related to Functional Safety and to Privacy (GDPR)

CCAM aspects to address

21Pauls Consultancy BV

21

Where do we stand in Standardisation

There has been identified many standardisation improvements to enable CCAM.

• A number of new work-items have been created and are worked on. New ones are expected in the near future.
