13. 04 December 2006 12 CS Video Conferencing Additional 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. 04 December 2006 13 3GPP2 Packet Switched Video Telephony Services (PSVT/MCS) C.P0055-0

15. 04 December 2006 14 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 Uses IETF AVPF packet loss feedback for providing dynamic error resiliency for video. Feedback enables encoder to adaptively insert redundancy (intra- refresh) in the video stream as needed to stop propagation of packet loss errors Defines FlowProfileID parameter for SDP to enable more efficient negotiation of RAN QoS resources. Allows the two terminals to better coordinate E2E QoS. Defines optimized procedures for establishing RAN QoS when multiple codecs are supported in the terminals. Support defined for 3GPP2 IMS and 3GPP2 non-IMS networks

16. 04 December 2006 15 PSVT Network Reference Model Network Reference Model for Non-roaming Mobile-to-Mobile PSVT Call

17. 04 December 2006 16 PSVT IMS Network Reference Model Network Reference Model for Non-roaming Mobile-to-Mobile PSVT Call over IMS

18. 04 December 2006 17 PSVT RAN and PDSN Protocol Stacks Protocol Stack when HDLC framing is applied Protocol Stack when segment-based framing is applied

19. 04 December 2006 18 PS Video Telephony Codec Support Other speech codecs, although not specified by C.P0055-0, are allowed and supported through SIP SDP negotiation between endpoints

20. 04 December 2006 19 PSVT Protocol Stacks over IP

21. 04 December 2006 20 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

24. 04 December 2006 23 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. 04 December 2006 24 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
