3. Video Conferencing & Telephony Specification Development within 3GPP2

4. TSG-C WG1 Structure 3GPP2 video conferencing and telephony service specifications developed by TSG-C SWG1.2

5. 3GPP2 Video Conferencing and Telephony Specifications

6. 3GPP2 Development Timeline

7. 3GPP2 Circuit-Switched Video Conferencing ServiceC.S0042-0

8. CS Video Conferencing Overview • C.S0042-0 defines video conferencing SO 57 & 58 at 32 and 64 kbps, respectively, over the air interface (carried in RLP) • ITU-T H.324 (Terminal for Low Bitrate Multimedia Communication) with Annex C used for video conferencing • ITU-T H.245 (Control Protocol for Multimedia Communication) version 7 (or greater) used for capability negotiation between terminals • ITU-T H.223 (Multiplexing Protocol for Low Bitrate Multimedia Communication)with Annex A & B used formultiplexing video, audio,and application layercontrol data

9. CS Video Conferencing Service Configuration Attributes

10. CS Video Conferencing Protocol Stack Video Conferencing Call Setup and Bearer Protocol Stack

11. CS Video Conferencing Codec Support

12. CS Video Conferencing Call Setup

13. CS Video ConferencingAdditional Capabilities • Supports video conferencing with 3GPP-324M terminals • SO 58 (64 kbps service) invoked over cdma2000 channel • IWF acts as gateway for video conferencing negotiation and control messages and EVRC to 3GPP-AMR speech transcoding

14. 3GPP2 Packet Switched Video Telephony Services (PSVT/MCS) C.P0055-0

15. Packet Switched Video Teleconferencing (PSVT) Overview • C.P0055-0 defines support for one-to-one conversational video services on 3GPP2 networks between: • Two mobile terminals • A mobile terminal and a video terminal on the Internet • Defines minimum requirements to ensure interoperability within 3GPP2 networks as well as optional capabilities and feature support to enable interoperability across other networks and technologies • Support defined for 3GPP2 IMS and 3GPP2 non-IMS networks

16. PSVT Network Reference Model Network Reference Model for Non-roaming Mobile-to-Mobile PSVT Call

17. PSVT IMS Network Reference Model Network Reference Model for Non-roaming Mobile-to-Mobile PSVT Call over IMS

18. PSVT RAN and PDSN Protocol Stacks Protocol Stack when HDLC framing is applied Protocol Stack when segment-based framing is applied

19. PS Video Telephony Codec Support

20. PSVT Protocol Stacks over IP

21. PSVT Feature Initialization • Feature Initialization occurs prior to PSVT call origination or termination. • Initialization tasks: • Configure & activate QoS for transporting SIP traffic • Configure QoS for transporting voice & video traffic • Configure QoS for transporting RTCP packets for voice & video streams. • Negotiate ROHC parameters for compressing the voice and video traffic • SIP Proxy or IMS core network P-CSCF registration

22. PSVT Call Setup

23. PSVT Call Release

24. PSVT In-Call Media Management C.P0055-0 defines SIP-based mechanisms for: • Adding Bi-Directional Video to a VoIP Call • Removing Bi-Directional Video from a PSVT Call • User-Initiated Removal of Video from a PSVT Call • Network-Initiated Removal of Video from a PSVT Call

25. PSVT Supplementary Services & Functions C.P0055-0 defines support for the following optional services & functions: • PSVT Voice Retry • Retry PSVT Call Origination as VoIP • Retry PSVT Call Reception as VoIP • Retry PSVT Call Origination as 1x Circuit-Switched Voice • Retry PSVT Call Reception as 1x Circuit-Switched Voice • Video/Media on Hold

26. C.P0055-0 PSVT Development Status • C.P0055-0 V&V Comment Resolution occurring this meeting cycle • Anticipate TSG-C approval for publication at end of this meeting or in January 2007
