Agenda of the presentation

3 France Telecom Group confidential

New market opportunity: Connection to the internet everywhere on the road depending on radio coverage

and technology used, providing infotainment services for increasing passengers comfort. Mobility and comfort services for drivers and passengers (ex POI for EV charging, multimodal Platform information, media downloading, ecologic drive, fleet management, M2M services…) more generally : Value Added Services

Intelligent Transport Systems: context

Orange Labs Networks – V2V/V2I and LTE cooperation

Primary public objective: reduction of car accidents, providing road

operators the possibility to warn drivers for route hazard or using communication systems for impact avoidance Road safety services (ex stopped vehicle, wrong way driving, hard braking, speed limits)

Ecological purpose: transportation and traffic regulation optimized,

allowing reduction of petrol consumption and emissions of green house effect gases Traffic management services (ex road information, in vehicle signage, traffic information and route/navigation guidance)

ITS : Intelligent Transport System is a new domain of Telecommunication field designed for vehicles and oriented in 3 different services corresponding to political objectives:

Global ITS architecture

Global ITS architecture for the delivery of cooperative services

Communication modes: V2I /I2V communications

between vehicles and infrastructure (HSPA, WiFi802.11n, ITS G5(802.11p), LTE)

• V2V communications (one and multi hop) between vehicles and RSU in 802.11p VANET ad hoc networks (geonetworking)

• Hybrid mode combining V2V+V2I communications : IPv6 over GN over ITS G5 and IPv4/v6 over 3G/LTE

POI provided by multimodal platform : features

aggregation/compilation/smart filtering/ of information data to deliver relevant/easy to use/handle information to vehicle driver and passengers

introduction of context aware information services to address population of users (social networks cooperation)

management of information data to deliver geo localized services to vehicles:

– dissemination of POI to infrastructure and vehicles according to time and position of ITS stations (relevant and real time information)

– introduction of increased reality processing to improve accuracy and performance of service information (ie parking information with drive queues and paths)

Benefits brought by POI in smart cities

Orange Labs Networks - New PFME POI for connected cars in smart cities

POI Benefits in 3 main domains: economic

optimization of travel time and budget thanks to real time transportation services

electronic business in car (consultation/reservation) ecologic

reduction of energy consumption (early knowledge of location/events)

promotion of sustainable transport and reduction of carbon footprint

social best organization of user trip/ reduction of wasting time reduction of stress during travel access to social services

ConclusionChallenges Large experience of Orange Labs to address the challenge of communications in the

connected car domain: Cooperation of heterogeneous cellular and vehicular networks combined with IP

mobility management OLN mobile router integrates complete ITS stack (standalone OBU designed to cope

with automotive systems requirements) Benefits Combination of Networks complementarity/mobility management is necessary to:

Enable efficient ITS communications which deliver service continuity to vehicular customers

Provide full fledge of connected services from safety and warning towards connected navigation & infotainment

Telecom Operators contributions Telecommunication operators acting to promote new vision in the ITS eco system:

To manage cooperation of operator networks with ITS ad hoc networks in an efficient way

To operate V2V and V2I communications and create new opportunities of cooperative services

To promote ITS service development & deployment for third party (fully involved in the definition of release2 of ITS standard)
