Course Overview:
The course provides the core theoretical knowledge that describes, in depth, all Roaming related subjects as well as the 3G/4G cellular networks in general.
As a background for understanding the Roaming architecture, operation and services the course reviews IP basic procedures and routing capabilities as well as SS7 signaling focusing on the SCCP/TCAP protocols. In addition the course covers in depth UMTS architecture and procedures from power-on of the mobile to call originating and terminating, in the visited network (roaming). The Course describes the different types of international roaming and the mechanisms that enable roaming calls and data session scenarios including SS7/IP 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.
