These example services can be offered with other technologies...
But IMS offers the ability to deliver these services using a single platform
Faster service development
Little or no network upgrades for new services
Link the voice, video, and data platforms

Summary
IMS is evolving into the SIP service delivery platform of choice for various industry sectors (wireless, DSL, cable)
PacketCable 2.0 enhances the IMS to meet the needs of cable operators
CableLabs is working with 3GPP to incorporate cable’s requirements directly into the IMS
Innovative applications that link the broadband platforms can drive customer growth and retention
