The SS7 Signaling in Mobile Networks course explains and describes the world’s most widespread inter-exchange signaling system used in fixed and mobile telecommunication today: Signaling System No 7. It provides the basic ideas and structure of the SS7 protocol stack. Different aspects of various signaling protocols and signaling applications in the telecommunications world are covered. There are a few detailed examples from both mobile and fixed networks.
The course focus is on ITU SS7 and GSM/UMTS core network protocols that are based on SS7 system. The participants will also gain a general understanding of how to interpret log files and traces taken from live networks.
