Course title Next Generation Network - IMS/ TISPAN
 
Course description IMS is developed by 3GPP to support the early third generation mobile UMTS access network. ETSI has developed TISPAN as a standards environment delivering the same functions for converged Next Generation fixed networks. Multi-media services over third generation mobile networks is supported by IMS and TISPAN integrates this with new fixed next generation infrastructures. Broadcast and multicast delivery of video and television will further expand the capabilities.
 
Who would benefit Those working in the TISPAN area requiring an understanding of the architecture and functions of the protocols.
 
Prerequisites Basic experience of UMTS and IP networks is an advantage but not compulsory.
 
Length 3 days
