Presentation Transcript

  1. Topics • Challenges and complexity • Customer perspective • Service provider perspective • 3G new breed of services • Solutions & protocols

  2. The Challenge • Hybrid solutions of WiFi/WiMAX and 3G/GSM enabled devices - next step in Mobile Broadband evolution • From a consumer perspective, these technologies should operate seamlessly • This hybrid of technology convergence • Introduces new challenges • Requires knowledge of a wide range of technologies Howcan the customer use it? What about the user experience?

  3. The Complexity • Convergence • Access (XDSL, Cable, Wi-Fi, WiMAX, 3G, …) • Networks (CS, PS, radio) • Device (per technology vs. cross technology) • Service (Service per network vs. unified services) • Technologies(DMH, UMA, FMC, IMS) • Mobility(network independent services) • Coverage(roaming, handover, handoffs) • Usability(How can customers use it?) • Services(Quad play – voice, video, data, mobile)

  4. IMS DMH WCDMA CDMA2K PSTN WiFi WiMAX PacketCable FTTx PSTN/DECT 2/2.XG FMC UMA The Broad Picture - WiMax Convergence The real developer challenge…

  5. Customer objective: Preserve existing services • No change in phone number • Incoming calls “follow me” • Outgoing calls have same caller identity • Synchronized address book • One dial plan • Voice quality • Security • Telephony • Emergency call • TTY • SMS, MMS • Data/ Internet • Location Service • Supplementary Services (e.g. Caller ID, one voicemail, 3-way conference)

  6. Customer objective • Identical user experience • Additional services: • Simplify call forward between wireline and wireless • Alarm system • Fax • Mobile stations to act as cordless phones when at home, calls idle phones when busy • Intercom feature • Multimedia services • One consolidated bill • Reduced cost, time, and hassle

  7. Customer objective (cont.) • Works on multiple networks (enterprise, home, home office, cellular) • Coverage and seamless transitions (roaming and handover) between networks

  8. Service provider objective Increase ARPU • Providing mobile access at home or in the office to increase usage by customers • Poor coverage at a subscriber’s home or office ranks as a primary reason for subscriber churn • Keep customers on their networks where ever possible to avoid roaming or other related charges while on other networks • Seamless integration of additional services (e.g. multimedia)

  9. Service provider objective: Services • Quad play services to its customers • Bundled services from its inventory of services • Enter the mobile loop market by providing converged fixed/mobile services • Customer experience the same or better than that offered by competing mobile service providers • All services to perform as well, independent of the access/ network including call-setup time, voice quality, data rates, etc. • Use existing core network to deliver all services, including authorization and billing, for licensed and unlicensed access

  10. 3G New Breed of Services • Enhanced Messaging • Video Mail (VM) • Advanced Multimedia Advertisement • Multimedia Messaging (MMS) • Conversational Multimedia • Push-To-Talk (PTT) over Cellular (PoC) • Push to Show/ Push to View • Videoconferencing for business or private use “on the go”

  11. 3G New Breed of Services (cont.) • Video Streaming • Live video broadcasting – TV on the go • Video On Demand (movies, news clips) - VOD • Video session archiving services • Playback & recording • Peer to Peer • Video Chat • Interactive gaming • Video sharing (“See what I See”/ “We share”) • Collaboration

  12. 3G New Breed of Services (cont.) • Complementary services • Presence aware services • Location aware services

  13. The Solution • Only IP can do it all and integrate services: • Voice • Video • Presence • IM • Mobile • 3G • Using: • IMS/MMD • SIP • IPPBX • Softswitches

  14. Service Enabler Protocols • Enhanced Messaging • SIP or 3G-324M – Video Mail (VM) • 3G-324M or SIP – Multimedia Advertisement • SIP – Multimedia Messaging (MMS) • Conversational Multimedia • SIP - Voice • SIP/PoC – Push-To-Talk (PTT) over Cellular (PoC) • 3G-324M or SIP – Video Telephony & Conferencing • Video Streaming • 3G-324M (DTMF based video portals) • RTSP (IP TV, surveillance) • Multimedia Gaming • SIP/JSR-180 (J2ME) • SIP/PoC

  15. Services & Protocols • Push-To-Talk (PTT) over Cellular (PoC) • POC Consortium/ Open Mobile Association (OMA) specification • Based on SIP RFC3261 & RTP/RTCP RFC3550/1 • Presence & IM/MMS • SIP RFC3261 + SIMPLE WG specifications • SIP MESSAGE & MSRP • Video telephony/ conferencing • 3G-324M • IETF XCON • Video on Demand (VoD) • Real Time Streaming Protocol (RTSP) RFC2326 • 3G-324M

  16. UE Solution Architecture Application GUI UDP/TCP/IP Telephony Presence Media Streaming Video Services POC RTP /RTCP SIP (SigComp) SIMPLE RTSP 3G-324M CS

  17. Other UE Requirements • 3GPP/2 SIP • IPv4/IPv6 support for signaling and media • PoC support • SigComp • Mobile IP enablement • Dynamic IP enablement • Advanced RTP/RTCP (RFC 3550/1) • RTSP • SRTP • J2ME JSR 180 enablement • Support for feature/ smart phone
