UMTS Core Network Planning

Course Description

The course “UMTS Core Network Planning” addresses the planning and design principles of the UMTS core network systems and related transmission networks. The core network architecture concerned is based on the split architecture mainly, taking into account dimensioning criteria for control layer and connectivity layer systems. Both core network domains (i.e. Circuit and Packet Services domains) are addressed in this course.
Traffic and signalling parts of the core network are dealt with in terms of functionality, protocols and traffic volumes. The processing requirements on core network systems is also addressed, by describing different processor load types and proposing methods for calculating expected processing capacity.
Let your staff learn from the experts that have already seen and solved the problems your staff is facing today.
