Training Course Outline
Course Duration:
2 days
Training Course Description:
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.
Course objectives:
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
