  1. Workshop on ICT Technologies & Standards for NGN, 3G & FMC Anticipating the benefits of IMS for the service offering Carlos Akio Matsumoto mês/2004

  2. About CPqD ...

  3. Technological and Business Areas Telecommunications Networks Business and Operations Support Systems Wireless Communication Optical Communications Services & Applications Business Intelligence Network Infrastructure

  4. Share Ownership

  5. What is IMS ? • IP Multimedia Subsystem • Unified Network Architecture for service offering • A functional model structured in levels • Service oriented NGN

  6. ... And Services Value Added Services Fixed Network Mobile Network Data Network Network Convergence IP Net Legacy Net

  7. NGN Model IN(Services) Service Standard Interface (SIP) Services Session Control Call Control Standard Interface (SIP/MGCP/H.248) X Trunk Subscriber Transport User Equipment TDM Architecture NGN Architecture

  8. Application Servers (AS) OSA/Parlay SIP OSA/Parlay SIP OSA/Parlay SIP IM-SSF SGW MGCF HSS CSCF MRFC SIP Endpoint Packet Mobile WLAN MRFP MGW IMS Architecture IMS Architecture Services Standard Interface (SIP) Session Control Standard Interface (SIP/MGCP/H.248) Transport & User Equipment NGN Architecture

  9. IMS Architecture (simplified) Application Servers (AS) SCP OSA/Parlay SIP OSA/Parlay SIP OSA/Parlay SIP IM-SSF Intelligent Network SGW MGCF HSS SS7 CSCF MRFC STFCeCircuitMobile SIP Endpoint Packet Mobile WLAN MRFP MGW IMS Architecture

  10. Current Status of Network • Old-fashionned access network(“no” packet mode transport) • Obsolete TDM Switching • NGN deployed partially • Value Added Service Platform running over circuit switch model and integrated at Telecom Operator’s Operational Process

  11. Where do Investments? • Maximize investiments on applications: • new services offering • differentiate offering over market competition • new revenue sources • Minimize investments on Infrastructure: • Maximize usage of TDM network • Focus investments on new technologies • minimize investments on legacy network

  12. Technical View • 3GPP and 3GPP2: focus on 3G network evolution • TDM network are connected to IMS environment throughout Trunking Media Gateways.

  13. Issue #1: • High CAPEX: IP backbone & gateways; • Multi-vendor environment: NOT Real; • Real Deployments: only when RoI is guaranteed ~ 30% ~ 70% NGN-By-The-Book and Main Issues - #1 Value Added Services VAS Softswitch Trusted Network IP Network TGW TGW TGW TDMNetwork

  14. TV2=NGN Traffic Volume N (C4/C5) • Issue #2: • TDM Calls NOT “visible” to NGN Value Added Services • TV1 >>> TV2 • Conclusion: Low Level of NGN adoption. TV1= TDM Traffic Volume (C4/C5) L ! $$, NGN-By-The-Book and Main Issues - #2 Value Added Services • Issue #1: • High CAPEX: IP backbone & gateways; • Multi-vendor environment: NOT Real; • Real Deployments: only when RoI is guaranteed VAS Softswitch Trusted Network IP Network TGW TGW TGW TDMNetwork

  15. How to offer Value Added Services to TDM traffic ? or... How to deploy converged services ? Convergence: Possible ? How to migrate ? Value Added Services VAS Softswitch Trusted Network IP Network TGW TGW TGW TDMNetwork

  16. SS7 / IN / CAMEL SCP Signaling and Service Converged Platform Gatewayless NGN • Signaling Server • (intrusive PTS with services) • Audit & Report of ss#7 Messages • Usage billing records from ss#7 messages> • Local Call • Long Distance Call SS7 SS7 Softswitch Migration Solution: Softswitch+Signaling Server Value Added Services VAS Softswitch Trusted Network IP Network TGW TGW TGW TDMNetwork

  17. =>Benefits of that Strategy Infrastructure Investment Reduction control infrastructure 77% NGN “by-the-book” Gatewayless NGN Gatewayless NGN Solution Value Added Services Signaling and Service Converged Platform SS7 / IN / CAMEL Local Call Long Distance Call

  18. Trunk Media Gateway at that new paradigm • Trunk Media Gateway will be connected only when media resource is required from IP Network

  19. Legacy Network connected to IMS (By-The-Book) PLMN OSA/Parlay SIP OSA/Parlay SIP OSA/Parlay SIP IM-SSF SS7 Media Gateway IMS core HSS CSCF SGW SS7 Media Gateway MGCF PSTN MRFC MRFP

  20. Session Control for Circuit Switched Network- signaling PLMN OSA/Parlay SIP OSA/Parlay SIP SS7 OSA/Parlay SIP IM-SSF Media Gateway IMS core HSS CSCF SGW SS7 Media Gateway MGCF PSTN MRFC MRFP

  21. Session Control for Circuit Switched Network - voice PLMN OSA/Parlay SIP OSA/Parlay SIP OSA/Parlay SIP IM-SSF Media Gateway IMS core HSS CSCF SGW Media Gateway MGCF PSTN MRFC MRFP

  22. How do Invesment ? • Investment on IMS Core • Common infrastructure that allow new services offering for any network access • Investment on Application Servers • New revenue based on new services. • Minimize investment on control and transport Infrastructure • Trunk Media Gateway is transition equipment • No further function for Trunk Gateway on 3G Networks Investment on Trunking Media Gateways is NOT investment on NGN!It is investment on LEGACY NETWORK!

  23. Session Control for Signaling and Service Platform PLMN OSA/Parlay SIP OSA/Parlay SIP OSA/Parlay SIP IM-SSF IMS core HSS CSCF Media Gateway MGCF PSTN MRFC MRFP

  24. Session Control for Signaling and Service Platform - signaling PLMN OSA/Parlay SIP OSA/Parlay SIP OSA/Parlay SIP IM-SSF IMS core HSS CSCF Media Gateway MGCF PSTN MRFC MRFP

  25. Session Control for Signaling and Service Platform - voice PLMN OSA/Parlay SIP OSA/Parlay SIP OSA/Parlay SIP IM-SSF IMS core HSS CSCF Media Gateway MGCF PSTN MRFC MRFP

  26. Example 1: Media resource from IP Network (Media Gateway) PLMN OSA/Parlay SIP OSA/Parlay SIP OSA/Parlay SIP IM-SSF IMS core HSS Media Gateway CSCF MGCF PSTN MRFC MRFP Media Gateway 80% Reduction on Media Gateway Investments

  30. CONCLUSION • IMS Migration Advantage: centralized VAS platform • VAS delivered for any access network • Investment focused on new Value Added Services • Standard Interfaces - Open protocols (Multi-vendor environment) • Gatewayless proposal: • Platform for call and service control: • Legacy network (TDM) • NGN network … or ANY combination of these networks • Unifying legacy and NGN Service Platform • Legacy network (TDM) connected with IMS in a optimized resource allocation • Evolve to IMS
