H.324 / M InteroperabilityChair Bernhard Wimmer
  • Observations
  • The IMTC is the appropriate forum to champion
    this work
  • H.324 is pretty much settled
  • New H.324 Mobile Product Implementations are
    emerging due standardization by 3GPP
  • Recommendations
  • Develop H.324/M Interoperability Test Plan and
    Score Sheet
  • Coordinate H.324 Interoperability Test Events
    with 3GPP (and ITU-T SG16)
  • Educate Members on latest Standards Updates
  • Provide feedback and suggestions for improvements
    to 3GPP
  • Encourage use of reflectors for e-mail
    discussions on implementation issues
  • Contribute to H.324/H324Mobile interworking
    planning.

3GPP 3G-324M Overview
  • ITU-T developed H.324 Mobile extension (H.324M)
  • H.324 Annex C has been established in 98.2
  • 3GPP extended H.324 Annex C
  • 3G-324M has been established in 99.12
  • Specified the audio/video CODECs suitable for
    Wireless Network
  • Mandatory support of AMR speech CODEC
  • Mandatory support of H.263 baseline
  • Optionally but recommended support of MPEG-4
    Simple Profile _at_ Level 0
  • Specified the multiplexing for Wireless Network
  • Mandatory support of H.223 Level 2 (Annex B)
  • Added several clarifications
  • Based on the interoperability test carried out by
    the interested companies
  • Described in 3G-324M Implementors Guide

Building Blocks of 3G-324M/ H.324M
  • H.223 multiplexed bitstream is mapped onto
    digital channel
  • Bearer control messages are delivered as in-band
    data
  • Modem/Mode negotiation is not applied
