Course Overview
The course provides the core theoretical knowledge that describes all the issues of GSM/UMTS telephony with focusing on roaming service.
The course starts on a comprehensive detailed SS7 signaling chapter, focusing in the SCCP/TCAP protocols, which are essential for the GSM operation especially roaming service. Main GSM/UMTS procedures will be covered in the course from power-on of the mobile to call originating and terminating, in the visited network (roaming). A special attention will be provided to the roaming calls scenarios including SS7 messages and transactions between visited to home networks. The course will also deal with the international operators supporting roaming and international SMS exchange, GSMA standards, Roaming billing and operational processes between operators around Roaming service.
