UMTS for Experts

Course Description

The course “UMTS FOR EXPERTS” gives a detailed description of post-R99 system architectures, their configuration options and additional features. Opportunities will be given to investigate in-depth, features and issues of particular interest for the participants.
The focus is set on the Radio Access Network, but the CN is also covered. Multi-RAB options, flexible Iu configurations and pooled SGSN/MSCs are detailed, as well as the new features like IP enabled QoS across the core and radio infrastructures. Finally, the evolution of UMTS and its relation to 4G/LTE is featured. The course is designed with respect to the participants’ high qualification.
