UMTS Signaling Protocols
4 days  (Instructor Led Online)  |  Mobile Networks (Insoft Specials)

Course Details

The UMTS Signaling Protocols course aims to provide trainees with specific knowledge on UMTS mobile network signaling protocols. Thanks to a signal flow depth analysis it is possible to fully understand the meaning of each signal message sent from and to access equipment and core network exchanges, concerning both UMTS voice or video calls, and 3G or 3.5G High-Speed Data.

In this course, we will provide you with a detailed protocol tracing analysis, with particular focus on the messages, exchanged between network elements during UMTS Voice calls and Data transmissions. Thanks to this kind of study, it will be easier to understand each 3G network signal flow.
