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

Vehicle Gateway Platform (Q27/16)

General use cases of Car Communications Vehicle to Vehicle Vehicle to Infrastructure Vehicle to Home Inside Vehicle Use Cases

Overall reference configuration model for VGP Main areas recognized to be standardized 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

Q27/16 Work Plan Recommendation Target Date H- or F-Series Supplement Framework of vehicle based telecommunications End/2009 F.VGP-REQ Service and Functional Requirements of Vehicle Gateway Platforms H.VGP-FAM Functional Architecture model of Vehicle Gateway Platforms H.VG-OIF Open interface between the Vehicle Gateway and ICT devices Mid/2010 H.VGP-PRT [Note 1] Service capabilities and protocols to support Vehicle oriented services End/2011 [Note 1] This document may consist of a set of different documents according to the layering models and required protocols. This needs further study.

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

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

Generic network configuration Mobile Phone IP packet network SPNE-T MGW-O MGW-T BSC-O MSC-O MSC-T Server Media Path Signalling Path Land User SC-T Circuit-Switched network Q.115.x G.mdcspne

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

Example of coordination Yes No Enabled Disabled Noise reduction (NR-T) for media from the land user Echo Cancellation (EC) for Sin from the land user Noise reduction (NR-O) for media from the mobile user Acoustic Echo Control (AEC) Tandeming (results) SPNE-T MGW-T MGW-O MS-O Voice enhancement　processing functions (Dynamic coordination) G.mdcspne Q G Q.115.x (Call set-up)

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.

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
