Common IMS (1)

• Material from several IMS/MMD-related documents
  has been included in the Rel. 8 Common IMS
  initiative in 3GPP. As a result, the following
  TIA standards will be capped, with any further
  enhancements to be undertaken in the
  corresponding 3GPP documents.
• 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

Interoperability and Inter-working

• Two projects are in progress in 3GPP2 to support
  IP level convergence
• HRPD/E-UTRAN Interoperability, and
• HRPD/WiMAX Interoperability
• Both projects will be ready for publication by
  EOY08

4
Strategic Direction

• TSB-183, Common IMS Impacts to 3GPP2
  Specifications, is being 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
  convergence

5
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

6
Next Steps/Actions

• Prepare additional documents in 3GPP2 for
  potential inclusion in Common IMS in Rel. 9
• TIA has recently been requested to publish
  TIA-1127, MMD Enhanced Policy, and 3GPP was
  notified that this is intended to be included in
  Rel. 9
• 3GPP2 has work items for IMS Centralized Services
  (ICS) and SIP-based Femto which are potential
  candidates for inclusion in Common IMS in Rel. 9
• As future IMS-based functionality is developed in
  TIA/3GPP2, applicability for Common IMS will be a
  key consideration
• Continue close collaborative work with 3GPP
