Migrating Toward PacketCable-with-IMS
3
Phase 1 Bypassing PSTN

• Only Support of the legacy devices (non-SIP
  based)
• SIP based Services that may be proposed in this
  Phase
• Click to Dial

4
Phase 2 Implementing P-CSCF

• conference calling
• call forwarding
• integrated voicemail and messaging

5
Phase 3 PacketCable-with-IMS

• single fixed/mobile numbering
• Unified Messaging
• Video on Demand (VoD) streaming to cell phone
• Content Sharing between Cell Phones, Personal
  Video Recorders (PVR) and other devices
• Remote PVR programming by cell phones
• Buddy List spanning devices

PacketCable 2.0 ArchitectureMaking IMS
cable-friendly
Reuse of 3GPP IMS Core Components I-CSCF,
S-CSCF, SLF, HSS
Similar to 3GPP IMS R7 Border Control Concepts
Reuse of 3GPP IMS Service Concepts and Interfaces
Interworking to existing PC 1.5 components. PC
1.5 MGC acts as an MGCF.
Builds on existing PCMM QoS architecture by
addition of PC 2.0 App Mgr (SOAP/XML i/f)
Includes BGCF per 3GPP IMS
Use of IETF defined NAT Traversal Mechanisms
(STUN, TURN, ICE)
Note some components re-used from 3GPP IMS have
additional incremental requirements over 3GPP IMS
