  1. Global Standards Collaboration (GSC) 14 NGN TIA Update on cdma2000® NGN Activities

  2. Common IMS (1) • Under the Common IMS Initiative, 3GPP and 3GPP2 successfullyrolled all the 3GPP2 enhancements to IMS back into the 3GPP specifications. Going forward, all further IMS work will be done in 3GPP, with member companies representing the needs of the CDMA community. • With the success of Common IMS, there is now a single IMS system for the industry

  3. Common IMS (2) • The following specifications have been capped in TIA accordingly: • TIA-873-B, All-IP Core Network - Multimedia Domain • TIA-1032-A, Presence Service • TIA-1069, Conferencing using the IP Multimedia Core Network • TIA-1091-B, IMS Security Framework • TIA-1111, VoIP Emergency Services • TIA-1112, SIP-ISUP Interworking • TIA-1125, Enhanced MMD Security, Stage 1 • TIA-1126, VoIP Supplementary Services Feature Descriptions • TIA-1133, All-IP Network Emergency Call Support, Stage 1 • TIA-1136, VoIP Supplementary Services

  4. Two projects are in progress in 3GPP2 to support IP level convergence e(evolved)HRPD/E-UTRAN Interoperability, and HRPD/WiMAX Interoperability The first releases of both were published in 1Q09, addendums and revisions are in progress and scheduled for completion EOY09. Interoperability and Interworking

  5. Strategic Direction • TSB-183, Common IMS Impacts to 3GPP2 Specifications, has been developed to provide both • a mapping of the 3GPP2/TIA documents to the 3GPP Common IMS counterparts, and • information regarding differences in IMS network elements and interfaces between 3GPP2/TIA and 3GPP specifications for inter-working purposes • Close collaboration between 3GPP2 and both 3GPP and WiMAX Forum is in place to support Interoperability and Inter-working

  6. Challenges • Ensure ongoing compatibility between TIA standards and Common IMS specifications • Ensure TIA requirements are met in the Common IMS specifications • TSB-183 will be updated appropriately as new CDMA-based material is incorporated into Common IMS • Maintain ongoing interworking between different access technologies

  7. Next Steps/Actions • Prepare additional documents in 3GPP2 for potential inclusion in Common IMS post Rel. 8 • TIA has published TIA-1127, MMD Enhanced Policy, and this may be proposed for inclusion in 3GPP Rel. 10, based on operator interest • As future IMS-based functionality is proposed in TIA/3GPP2, applicability for Common IMS will be a key consideration • Continue close collaborative work with 3GPP and WiMAX Forum
