  2. 3GPP2 Multimedia Session • Key Objectives • Multimedia Domain • Work Status • Convergence To Date

  3. Multimedia Session Key Objectives • Convergence with 3GPP • Common network entities • Common protocols • Common call/session APIs • Support for cross-technology roaming • Support for access independence

  4. Multimedia Domain • Support SIP sessions for • Home subscribers • Roaming subscribers • Support SIP capabilities for • Mobile origination • Mobile termination • Session redirection • Multi-party sessions • Media add/drop

  5. IP Network PSTN Multimedia Domain Position Determining Entity Databases Network Capability Gateway Service Application Position Server Subscription QoS Manager Legend - signaling - bearer - signaling and bearer - part of MM session arch - not part of MM session arch Session Control Manager Media Gateway Control Function AAA Core QoS Manager Access Gateway FA/Attendant Media Gateway BSC/RNC + PCF BTS Media Resource Function Controller cdma2000Access Network Border Router Media Resource Function Processor Mobile Station Mobile IP Home Agent

  6. Multimedia Domain • SIP protocol selected for • SCM-SCM • SCM-NCGW • SCM- MRFC • SCM-MGCF • Megaco protocol selected for • MGCF-MGW • MRFC-MRFP

  7. Work Status • Basic architecture defined • Focus group formed to develop Stage 2 & Stage 3 • Call flow adaptations initiated • SIP registration • Session origination • Session termination • Potentially meet/work jointly with other organizations

  8. Convergence To Date • 3GPP2 multimedia session common with 3GPP • Network entities • SCM=CSCF • MGCF, MGW • MRFC, MRFP • Network protocols • SIP • Megaco
