IMS was originally developed by an industry forum in 1999 after the publication of the early third generation mobile UMTS standards. TISPAN has been developed by ETSI as a standards environment delivering the same functionality for converged Next Generation fixed networks.  IMS systems can deliver multi-media services over third generation mobile networks and integrate this with new fixed next generation infrastructures. Extensions of this will further expand capabilities by adding broadcast and multicast delivery of video and television. It will also be possible to support peer-to-peer services.

A good understanding of how IMS can be implemented to match the appropriate international standards is critical for carriers and operators to be successful in delivering state-of-the-art services. This course will provide this understanding of IMS for technical professionals, managers and service planners.


When you have completed this course you will be able to:

  • Describe the standards for IMS and TISPAN
  • Discuss the architectures for implementation of IMS within carrier networks
  • Examine Fixed and mobile networks identifying what IMS can deliver
  • Consider the impact of SIP peer-to-peer services and VOIP
  • Determine the importance of adopting IPv6 and ENUM
  • Survey the benefits of IMS
