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 @
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 Implementor’s Guide
November 2001
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
