Duration: 5 days

Course overview
The technology convergence under the name ‘NGN, Next Generation Network’ is currently deployed in
both fixed and mobile networks. In UMTS mobile core networks, the concept is referred to as
‘Layered Core Network’ or ‘Split Architecture’. The implementation is based on a so called ‘Softswitch’
principle, which means that control and traffic functions within a UMTS Core Network are
implemented in physically separate systems, so called servers and media gateways. The logical
interfaces between these systems support new standardized signaling protocols, like BICC and MGCP.

The course provides knowledge of the UMTS Core Network and the protocols necessary for
implementing it. The focus of this course lies on the signaling protocols that render separations of
control and traffic functions. It gives a detailed picture of the most important UMTS Core Network
signaling protocols as specified by 3GPP Release 4 and Release 5.
Let your staff learn from the experts that have already seen and solved the problems your staff is facing today.
