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
