  2. 3GPP2 Service Architecture • Key Objectives • Legacy MS Domain • Multimedia Domain • Work Status • Convergence To Date

  3. Service Architecture Key Objectives • Home Service Control • Access Service Applications through the network • Access Service Applications from the mobile • Access Network Capabilities from Service Applications • Separate service control from bearer management

  4. Legacy MS Domain • Support for legacy (non-SIP) mobiles • Some network entities common with Multimedia Domain • Some protocols/APIs common with Multimedia Domain

  5. TIA/EIA-41 PSTN IP Network Legacy MS Domain Position Determining Entity Position Server Databases AAA Service Application Legend - signaling - bearer - signaling and bearer - part of Service Arch - not part of Service Arch Network Capability Gateway Access Gateway FA/Attendant BSC/RNC + PCF BTS Media Resource Function Processor Mobile IP Home Agent Media Gateway Border Router cdma2000Access Network Legacy MS Domain Support Mobile Station HLR emulation MSC emulation SCP emulation

  6. Multimedia Domain • Provide new multimedia services • Provide new telephony services • Integration of voice and data services • Multimedia services • Provide new packet data services

  7. 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 Service Arch - not part of Service 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

  8. Multimedia Domain • API under consideration for NCGW-SA • Parlay/OSA, with the following technology realization • JAIN SPA • SOAP/WSDL • CORBA IDL • Same/extension of OSA for Legacy MS Domain • Protocol under consideration for NCGW-PS • WAP • Protocol under consideration for NCGW-SCM • SIP

  9. Work Status • Basic architecture defined • Focus group formed to • Draft system requirements • Identify service drivers • Meet/Work jointly with other organizations

  10. Work Status • API/Protocol discussions in progress • Services under development • Presence • Instant Messaging • Multimedia Messaging • Multimedia Streaming • Location Based Services

  11. Work Status • Legacy MS Domain • Service Architecture work item initiated • Concept approved • Service Stage 1’s under development • Multimedia Domain • Service Stage 1’s under development

  12. Convergence To Date • 3GPP2 Service Architecture supports • 3GPP Parlay/OSA • Third party application provisioning and control • Rapid service creation • 3GPP SIP Application Server • lightweight application, built using the implicit session control mechanisms of the SIP protocol itself

  13. Convergence To Date • 3GPP2 Services common with 3GPP • Presence • Multimedia Messaging • Service concept is common, work needed to ensure common specification

  14. Convergence To Date • 3GPP2 API/Protocols common with 3GPP • Parlay/OSA with the following technology realizations • JAIN SPA • SOAP/WSDL • CORBA IDL • SIP • WAP?
