Course Objectives

This extensive five-day training provides a unique overview of signalling protocols that dominate in the architecture of contemporary mobile networks. Presented in a easy to follow and logical order this course discusses concepts ranging from basic Signalling System No 7 protocols with the focus on specific user parts through signalling transport in ATM and IP infrastructure, including SIGTRAN, to specialised protocols used in setting up bearers for multi-rate applications. Supplemented with a series of challenging exercises based on real network scenarios this training offers a great occasion to obtain a in-depth understanding of signalling concepts.

Pre-requisites

The participants are required to be familiar with overview of mobile networks and their services. Any knowledge of transfer technologies such as TDM, ATM and IP will be very beneficial.
