Outline

Telematics An OSGi-based approach for an open telematics market 3GT: enabling interoperability in telematics service delivery The 3GT implementation at the Munich test site Pushing the boundaries of OSGi Remote Management Field trials and interoperability testing Conclusions


What is Telematics?

Telcos: Teleservice as opposed to bearer service Commonly: Telematics = Automotive Telematics Historically:

Voice amplified by some lightweight signalling and information transfer protocol

Examples: GATS, ACP

Recently complemented by WAP and other online services Consumer not always the immediate end-point (cf. diagnostics) Evolving hybrid service delivery, i.e. involving both, on-board

and off-board components

Services delivered to the mobile user with specific focus on, or particular added value in

an automobile environment.


What is wrong withTelematics?

First generation telematics: Hardware-based dedicated single-service solutions Standalone, vertically integrated units Redundant designs, no synergies (Almost) no standardization

Second generation telematics: Partial standardization, especially on the signalling protocol Services tightly coupled with information transfer protocol Standards suffering from low acceptance and penetration Still high degree of proprietary system solutions Closed, embedded in-vehicle platforms

While there clearly is a market for telematics, its potential remains limited due to lack of openness.

Conclusions

Telematics still faces considerable horizontal market challenges and OSGi is a key enabling technology to address them

OSGi Remote Management is at the core of an end-to-end service delivery chain

3GT has defined critical interfaces to ensure interoperability: Deployment and provisioning of Service Applications Remote user session (login) and Service Gateway personalization Subscription and service object management

3GT specifications proven through extensive field trials The 3GT Munich test site has extended the concepts with security,

advanced personalization, vehicle management, and electronic payment features

3GT results and specification available to OSGito be considered for standardization.
