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

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

17Dynamic 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
