    • 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

Q.115.x (Call set-up)


Dynamic coordination of spne current status future plans

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

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
