Course Objectives

This extensive five-day training provides a unique overview of the signalling protocols that dominate the architecture of contemporary mobile networks. Presented in an easy-to-follow and logical order, during this course we discuss concepts ranging from basic Signalling System No. 7 protocols with a focus on specific user parts and signalling transport in ATM and IP infrastructure (including SIGTRAN), to the 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 is a great way to obtain an in-depth understanding of signalling concepts.



The participants must be familiar with the basics of mobile networks and their services. Knowledge of transfer technology such as TDM, ATM and IP is recommended.
