  1. TSG-N MMD Specification Status • Approach • Structure • Content • Key Cooperative Work Areas TSG-N

  2. Specification Approach • Three Logical Subsystems, allowing autonomous development of each: • Packet Data Subsystem (PDS) • IP Multimedia Subsystem (IMS) • Service Capability Subsystem (SCS) • Current work based on All-IP NAM version 2.0.2 • This version contains essential changes for Network Element Names, Reference Point Labels, and Service Architecture TSG-N

  3. Specification Approach • Packet Data Subsystem (PDS) • <graphic> • Identified so TSG-N can work on the other parts • The IMS and SCS subsystems interact with the PDS. TSG-N

  4. Specification Approach • IP Multimedia Session Subsystem (IMS) • <graphic> • Near-Term solution: Adoption of the 3GPP Release 5 IMS Specifications • Longer-Term: Access-Independent 3GPP Release 6 IMS Specifications • Realizing the Near-term solution: • Creation of Access Independent 3GPP2 IMS Specifications • Adaptation of 3GPP Release 5 Specifications for 3GPP2 PDS TSG-N

  5. Specification Approach (Cont) • Services Capability Subsystem • Work in progress. • WG OSA, Participation in the OSA/Parlay/ETSI/3GPP Joint API Forum TSG-N

  6. Practical Aspects • One Document for all TSG-N MMD Specifications • 3GPP2 WI # for: • 3GPP2: N.P0024 (to be published as N.S0024) • TIA/EIA: PN.4935 (to be published as • Structure: • High-Level, 3GPP2 specific Specification • Stage 2 Level Specification (IMS+SS) • Sub-sections, defined in individual documents • N.P0024.02: • … • … • Stage 3 Level Specification (IMS+SS) • Subsections • Schedule • 3GPP IMS Release Content • Potential Joint work: . TSG-N TSG-P TSG-S • IMS Security p • Session Policy Ctl ? ? - TSG-N

  7. Key Interactions between PDS and IMS • <16/cx> • <session/bearer association> • <IMS Authentication> TSG-N

  8. Key Interactions between PDS and SCS • <7,11/sh> TSG-N
