
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
18

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
