GTP signalling has been a part of mobile network signalling since the mid-1990s. Since these messages travel on the GPRS Exchange (GRX) or IP Exchange (IPX) between networks, they can be exploited at the interfaces exposed to those networks. And, just like SS7 and Diameter, GTP messages routinely carry a wealth of user data that can be exploited and manipulated. This module will identify the risks and countermeasures.

This module looks at the different types of Interconnect relationships that can be established.

In this module we learn about the commercial aspects of running Interconnects and the related operational processes needed to maintain Interconnect relationships.

This module introduces the students to telephone numbering as a key resource enabling inter-connectivity as well as the concept of Number Portability that enables free movement of subscribers between networks. We also talk about the cost and revenue risks associated with interconnect.

Module: In this module, we will start by giving a brief overview of the various SS7 layers and their security issues.

COURSE: This course introduces students to the field of interconnect.

COURSE: We examine the overall security challenges that arise when mobile networks interconnect.

COURSE: This course is for anyone who wants to understand the basics of SMS Interworking.

COURSE: SMS may be 25+ years old but MNOs continue to make increasing amounts of margin from it
