    IP Cons : Delay Sensitive Applications
       Conversational multimedia and video streaming
          needs fixed delay which IP V4 can not assure

       IP V4 addressing scheme is too limited for mass
         market mobile use

       IP V6 can address delay-sensitive and addressing
        requirements but…
          When? Who will pay? ROI?
          Long deployment paths: Interoperability, OSS
          IPv6 addressing scheme worldwide definition/actual deployment
          Complete IPv6 networks. Hybrid of IPv4 & IPv6 = QoS of IPv4

                          What is 3G-324M ?

                    Defined by 3GPP (Release 4, 1999)

                    3G-324M protocol “rides” on an opened fixed delay
                     circuit switch channel between call parties

                    Enables real-time multimedia (voice, video, data)
                     conferencing, steaming and application sharing

                    Can operate above any 32Kbps or faster bi-directions
                     bit steams

                    Currently defined by 3GPP for Wideband Code Division Multiplexing
                     (WCDMA) 3G Air interface

                    Lately 3GPP2 approved CDMA2000 integration spec with 3G-324M
                     Technical Spec C.S0042 (August 6, 2002)

                                3G-324M Concepts


                Technology concepts

                           Based on ITU H.324M with enhanced reliability for
                            error-prone networks

                           Reuse existing Air interface signaling to establish a call with
                            circuit switch channel

                        Multiplexing   of call control and multimedia channels to one bit stream
                              –H.245 Call Control Channel
                              –Voice Codec (AMR)

                                         Conclusion
               3G-324M is a proven solution for differentiated 3G
                conversational and streaming multimedia services
                for UMTS/WCDMA 3G wireless networks.
                It works NOW

               Provides added-value services
                E.g. DoCoMo’s Mstage V-Live
                “live streaming to numerous handsets”

               Main technical and economy drivers
                        Overcome  open issues in IP for conversational multimedia
                        and streaming services

                        Reuse  matured E.164 addressing methods,
                        assures fixed delay and well managed services by using
                        existing Circuit Switch (CS) infrastructures

                        Circuit   switch is heavily deployed and has longevity

                        Additional IP based services can be integrated as well
                        (e.g. Mail, Web, Gaming, SIP, H.323)
