  1. ITU-T SG16’s involvement in Car Communications Yushi Naito ITU-T SG16 Chairman Mitsubishi Electric Corporation

  2. Vehicle Gateway Platform and Dynamic coordination mechanism for seamless interaction between networks and devices

  3. Overview Who we are; The new structure of ITU-T SG16 Two projects under going; • Vehicle gateway Platform • Dynamic coordination mechanism of SPNE to achieve optimal end-to-end voice quality Solicitation for collaboration

  4. ITU-T SG16 (Study Period 2009-2012) Multimedia coding, systems and applications(23 Qs in total) Chairman:Yushi Naito (Mitsubishi Electric Corp., Japan) SG16 Network signal processing and voiceband terminals (4 Qs) Chairman: Mr. Harald Kullmann (DeutscheTelekom, Germany) WP 1/16 Q18/16 Applications and systems  (12 Qs) Co-Chairman: Mr. Seong-Ho Jeong (Hankuk Univ., Korea) Co-Chairman: Mr. Noah Luo (Huawei, China) Vice Chairman: Mr. Yoshinori Goto (NTT, Japan) WP 2/16 Q27/16 WP 3/16 Media coding  (5 Qs) Chairman: Ms. Claude Lamblin (France Telecom, France) Q 20 Multimedia coordination Q 26 Accessibility to Multimedia Systems andServices

  5. Responsibilities and mandates of SG16 SG16 is; • responsible for studies relating to ubiquitous applications, multimedia capabilities for services and applications for existing and future networks, including NGN and beyond. • the lead Study Group on Multimedia coding, systems and applications • the lead study group on ubiquitous applications ("e-everything", such as e-health) • the lead study group on telecommunication/ICTaccessibility for persons with disabilities

  6. Questions related to Car Communications Questions already undertaking • Q27(WP2/16)Vehicle Gateway Platform for telecommunication/ITS services / applications • Q18(WP1/16)Interaction aspects of signal processing network equipment • Questions working on potential areas • Q22(WP2/16) Multimedia applications and services • Q25(WP2/16) applications and sysytems • Q26(SG16) Accessibility to multimedia systems and services

  7. SG16’s involvements to Car Communications • Q 27 (WP2/16 Vehicle Gateway Platform for telecommunication/ITS services/applications) on; • Studies on the requirements in terms of services and functions to support V2V and V2I • Studies on the functions of vehicle gateway and its reference model(s) • Studies on the open interface between in-vehicle network and ICT devices • Studies on the relevant necessary protocols to support vehicle oriented services/applications • Q 18 (WP1/16 Interaction aspects of signal processing network equipment ) on; • Developing mechanism for dynamic coordination of SPNE to achieve optimal end-to-end voice quality

  8. Vehicle Gateway Platform(Q27/16)

  9. Vehicle to Home InsideVehicle Use Cases Vehicle to Infrastructure Vehicle to Vehicle General use cases of Car Communications

  10. I3 : Wireless/wired communication interface between Vehicle Gateway and ICT devices I5 : The interface between Vehicle-to-Vehicle communication I1 : The interface between the IVN and Vehicle Gateway Main areas recognized to be standardized Overall reference configuration model for VGP

  11. Q27/16 Work Plan [Note 1] This document may consist of a set of different documents according to the layering models and required protocols. This needs further study.

  12. VGP – current status & future plans • Q 27/16 is a newly established Question in WP2/16 • The main tasks are; • Studies on the requirements in terms of services and functions to support V2V and V2I • Studies on the functions of vehicle gateway and its reference model(s) • Studies on the open interface between in-vehicle network and ICT devices • Studies on the relevant necessary protocols to support vehicle oriented services/applications • Currently discussing the work plan and objectives • Collaborations with SDOs and Forums are envisaged

  13. Dynamic coordination mechanism of SPNE to achieve optimal end-to-end voice quality(Q18/16)

  15. Capability List Exchange Forward Capability List Received Forward Capability List Update • Each cell corresponds to specific Speech Processing Function • Speech Processing Function includes, but not limited to; • Network Echo Cancellation, • Acoustic Echo Cancellation, • Automatic Level Control, • Noise Reduction • Capability List received is added information if necessary, and sent to next SPNE for update • Each SPNE enables or disables its function based on pre-determined coordination rules SPNE Speech Processing Functions/Divices Signal Flow Reverse Capability List Update Reverse Capability List Received

  17. Dynamic Coordination of SPNE – current status & future plans • Q18/16 has almost got consensus on coordination mechanism and proceeded to discuss detailed designs, • Study on the protocols to exchange Capability Lists are necessary, • SG16 is asking SG11 and other SDOs for the guidance on the available protocols, especially for wireless links, • SG11 and other SDOs are invited to liaise with SG16 on these aspects, • Discussion on separating framework part and implementation-dependent parts is now under discussion. The target date for AAP consent on core part is expected to be October 2009.

  18. Conclusion • ITU-T SG16 is working on Vehicle Gateway Platform and System coordination for improving speech quality in Car Communications, • Evolving Car Communication technology can make driving environment safer, ecological, comfortable and human friendly, • To attain these ultimate targets, SDOs and Forums have to collaborate together to fill up the standardization gaps • ITU-T SG16, responsible for multimedia coding, systems and applications, is widely open for collaboration to attain these ultimate targets through Car Communication standardization
